A(n) _______ angle of a triangle is equal to the sum of the two remote interior angles.
-Exterior
-Interior
-Complementary
-Vertical

Answers

Answer 1

Answer:

Option A (Exterior)

Step-by-step explanation:

To understand this question, it is important to understand the concept of the exterior angle. An exterior angle is an angle which is made by two intersecting lines outside of the shape. Basically, one of the two lines is extended outside the shape. The angle between the extended line and the other line which is not extended is the exterior angle. It is outside the shape. The interior angle is the angle which is made by the same two lines but inside the shape.

The sum of the interior angle and the exterior angle is 180 degrees. It is also interesting to note that the sum of the angles in the triangle is 180 degrees.

Suppose that the angles in the triangles are A, B, and C, and the associated exterior angle with the angle A is angle D. By the argument, A+B+C=180 degrees and A+D=180 degrees. Since 180 degrees = 180 degrees, therefore A+B+C = A+D. Angle A cancels on both sides and reduces to B+C=D. This proves that the exterior angle of a triangle is equal to the sum of the two remote interior angles!!!

A box at a miniature golf course contains contains 4 red golf balls, 8 green golf balls, and 7 yellow golf balls. What is the probability of taking out a golf ball and having it be a red or a yellow golf ball? Express your answer as a percentage and round it to two decimal places.

Answers

Answer:

 =57.89%

Step-by-step explanation:

The total number of golf ball is 4+8+7 = 19

P (red or yellow) = number of red or yellow

                              ------------------------------------

                                total number of golf balls

                           = 4+7

                              -----

                              19

                         =11/19

Changing this to a percent means changing it to a decimal and multiplying by 100%

                        = .578947368 * 100%

                         =57.8947368%

Rounding to two decimal places

                         =57.89%

Final answer:

The probability of drawing a red or yellow golf ball from the box can be calculated by dividing the total number of red and yellow balls (11) by the total number of balls in the box (19), resulting in a probability of 11/19 or approximately 57.89%.

Explanation:

To calculate the probability of drawing a red or yellow golf ball from the box, we first need to figure out the total number of balls in the box. This is found by adding up the number of each color of balls: 4 red balls + 8 green balls + 7 yellow balls = 19 total balls.

Next, we consider the total number of red and yellow balls, which is 4 red + 7 yellow = 11.

To find the probability, we divide the number of desired outcomes (red or yellow balls) by the total number of outcomes (total balls). So, the probability is 11/19.

To express this as a percentage rounded to two decimal places, we can multiply the result by 100, which gives us approximately 57.89%. So, there is a 57.89% chance of drawing a red or yellow ball from the box.

What is the coefficient of x^4y^4 in the expansion (x+y)^8?

A. 1
B. 40
C. 70
D. It does not exist

Answers

Answer:

  C.  70

Step-by-step explanation:

In the expansion of (a + b)^n, the k-th term is ...

  nCk·a^(n-k)b^k . . . . . k = 0 to n; nCk = n!/(k!(n-k)!)

Here, we have n=8, k=4, so the term of interest is ...

  8C4·x^4y^4 = (8·7·6·5)/(4·3·2·1)x^4y^4 = 70x^4y^4

The coefficient of the term is 70.

A sequence of numbers a1, a2, a3, . . . is defined as follows: a1 = 3, a2 = 5, and every term in the sequence after a2 is the product of all terms in the sequence preceding it, e.g., a3 = (a1)(a2) and a4 = (a1)(a2)(a3). If an = t and n > 2, what is the value of an+2 in terms of t ?
(A) 4t (B) t^2 (C) t^3 (D) t^4 (E) t^8

Answers

Answer:

  (D)  t^4

Step-by-step explanation:

You have defined ...

  a3 = a2·a1

  a4 = a3·(a2·a1) = a3²

  a5 = a4·(a3·a2·a1) = a4² = (a3²)² = a3⁴

Then if a3 = t, a5 = t⁴

Let's begin by understanding the given sequence and the pattern it follows.
We are given the initial terms:
a1 = 3
a2 = 5
For n > 2, the next term is defined as the product of all preceding terms. Therefore,
a3 = a1 * a2
a4 = a1 * a2 * a3
and so on.
Now, let's generalize this for any term an where n > 2. According to the problem, an = t.
The term immediately after an would be an+1, which equals the product of all preceding terms:
an+1 = a1 * a2 * a3 * ... * an-1 * an
Since an = t, and every term before it has been multiplied to give t (by definition of the sequence), we have:
an+1 = t * t
an+1 = t^2
Now, let's find an+2. This term is the product of all preceding terms, which now includes an+1:
an+2 = a1 * a2 * a3 * ... * an-1 * an * an+1
From above, we know an = t and an+1 = t^2. Hence:
an+2 = t * t^2
an+2 = t^3
Therefore, the value of an+2 in terms of t is t^3. The correct answer is (C) t^3.

VWX and NOP are similar. If mV = 44° and mP = 66°, what is

A.
22°
B.
33°
C.
35°
D.
70°

Answers

Answer:

D. 70 degrees.

Step-by-step explanation:

Because the 2 triangles are similar corresponding angles are congruent.

So m < P = m< X = 66 degrees.

And since there are 180 degrees in a triangle:

m < W = 180 - (m < V + m < X)

= 180 - (44 + 66)

= 70 degrees.

The measure of the angle ∠W is 70°.

What is triangle?

A triangle is a two - dimensional figure with three sides and three angles.

The sum of the angles of the triangle is equal to 180 degrees.

∠A + ∠B + ∠C = 180°

Given is that two sides of a triangle measure 7 feet and 19 feet.

Since the triangles VWX and triangle NOP are similar, we can say that the corresponding angles of both triangles is same.

∠W = ∠O

Also -

∠O + ∠N + ∠P = 180

∠O = 180 - 110

∠O = 70°

∠W = ∠O = 70°

Therefore, the measure of the angle ∠W is 70°.

Answers

Answer:

[tex]\theta \in \{0,\pi,\frac{7\pi}{6},\frac{11\pi}{6}\}[/tex]

Step-by-step explanation:

[tex]\sin(\theta)+1=\cos(2\theta)[/tex]

Applying double angle identity:

[tex]\cos(2\theta)=1-2\sin^2(\theta)[/tex]

Doing so would give:

[tex]\sin(\theta)+1=1-2\sin^2(\theta)[/tex]

We need to get everything to one side so we have 0 on one side.

Subtract 1 on both sides:

[tex]\sin(\theta)=-2\sin^2(\theta)[/tex]

Add [tex]2\sin^2(theta)[/tex] on both sides:

[tex]\sin(\theta)+2\sin^2(\theta)=0[/tex]

Let's factor the left-hand side.

The two terms on the left-hand side have a common factor of [tex]\sin(\theta)[/tex].

[tex]\sin(\theta)[1+2\sin(\theta)]=0[/tex].

This implies we have:

[tex]\sin(\theta)=0 \text{ or } 1+2\sin(\theta)=0[/tex].

We need to solve both equations.

You are asking they be solved in the interval [tex][0,2\pi)[/tex].

[tex]\sin(\theta)=0[/tex]

This means look at your unit circle and find when you have your y-coordinates is 0.

You this at 0 and [tex]\pi[/tex]. (I didn't include [tex]2\pi[/tex] because you don't have a equal sign at the endpoint of [tex]2\pi[/tex].

Now let's solve [tex]1+2\sin(\theta)=0[/tex]

Subtract 1 on both sides:

[tex]2\sin(\theta)=-1[/tex]

Divide both sides by 2:

[tex]\sin(\theta)=\frac{-1}{2}[/tex]

Now we are going to go and look for when the y-coordinates are -1/2.

This happens at [tex]\frac{7\pi}{6}[/tex] and [tex]\frac{11\pi}{6}[/tex].

The solution set given the restrictions is

Answer:

△ABC ~ △DEF

Step-by-step explanation:

the AA (angle angle) postulate is a postulate that says two triangles can be similar if they have two congruent angles. using this postulate with how each triangle has a 90° angle and ∠F is congruent to ∠C, we can determine that △ABC ~ △DEF.

The correct answer is C. OBC DE because of the definition of similarity in terms of similarity transformations.

A similarity transformation is a transformation that maps a figure onto a similar figure. A similar figure is a figure that has the same shape as the original figure, but may be a different size and orientation.

A rigid transformation is a transformation that maps a figure onto a congruent figure. A congruent figure is a figure that has the same size and shape as the original figure.

Since a series of rigid transformations maps F onto C where F is congruent to C, then the rigid transformations must have preserved the shape and size of F. This means that the rigid transformations must have been similarity transformations.

Therefore, the statement "OBC DE because of the definition of similarity in terms of similarity transformations" is true.

Benito spent $1822 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for gasoline. If he drove 7340 miles, what was the average cost of the gasoline per mile?



Operating Expenses


Insurance $809


Registration $170


Maintenance $57



A. 61.06 cents


B. 10.71 cents


C. 1.27 cents


D. not enough information

Answers

Answer:

  B.  10.71 cents

Step-by-step explanation:

Benito's other expenses total ...

  $809 +170 +57 = $1036

so his gas expense is ...

  $1822 -1036 = $786

Then the per-mile cost is ...

  $786/(7340 mi) ≈ $0.10708/mi

Benito's gas cost averaged 10.71¢ per mile.

Answer is B) 10.71 cents.

You just add Benito's operating expenses togther, like so:

809 + 170 + 57 = $1036 so far.

Next, subtract the total amount he spent this last year (1822), with how much he spent so far (1036).

1822 - 1036 = $786

Finally, divide the final total with the 7340 miles he plans to drive.

786 ÷ 7340 = 0.10708

Answer is B) 10.71 cents.

Answers

Steps:

---> Re arrange equation to get the format: y = mx + c

---> Work out the perpendicular gradient from the first equation

----> Substitute the x and y coordinates of point (-1, 0) and the perpendicular      gradient into y = mx + c   and work out c

---> Finally, substitute the perpendicular gradient and the value for c into y =mx + c  to get the gradient of the perpendicular line:

__________________________________________

Rearranging equation into the format: y = mx + c:

[tex]5y = x - 5[/tex]                  (Just divide both sides by y)

[tex]y = \frac{1}{5}x -1[/tex]

___________________________________________

Working out the perpendicular gradient:

To work out the perpendicular gradient, we just take the negative reciprocal of the gradient of [tex]y = \frac{1}{5}x -1[/tex]

Note: negative reciprocal means we just flip the fraction and put a minus sign.

The regular gradient is: [tex]\frac{1}{5}[/tex]

So the perpendicular gradient is the negative reciprocal of [tex]\frac{1}{5}[/tex]

which is -5       (note: [tex]\frac{-5}{1}[/tex] is just 5-)

___________________________________________

Now lets substitute in the values for the gradient (m), the y coord (0) and x coord (-1) of the point (-1, 0)   into y = mx + c, and solve for c:

y = mx + c     (substitute in all known values)

0 = -5(-1) + c   (the -1 times -5 will make + 5)

0 = 5 + c        (subtract 5 from both sides to cancel out the + 5)

-5 = c

so c = -5

____________________________________________

Finally, just substitute in the perpendicular gradient and the value for c into y = mx + c   to get the equation of the perpendicular line:

y = mx + c        (substitute in the perp. gradient and c)

y = -5x - 5

____________________________________________________

Answer:

The equation to the line perpendicular to 5y = x - 5 through point (-1, 0) is :

C. y = -5x - 5

_______________________________________________

A quicker way to get equation of the perpendicular line once you know the perp. gradient is to use the equation:

y - y1 = m (x - x1)

y1 is the y coordinate of (-1, 0)

x1 is the x coordinate of (-1, 0)

m is the perpendicular gradient.

y - y1 = m (x - x1)       (Substitute in values)

y - 0 = -5 ( x - - 1)       (simplify)

y = -5 (x + 1)              (expand the brackets)

y = -5x - 5

Since secant is the reciprocal of cosine, let's find the cosine of the reference angle and then flip it upside down.  The cosine of the angle is the side adjacent (got it) over the hypotenuse (don't have it).  We can find the hypotenuse using Pythagorean's Theorem:

[tex]c^2=-3^2+4^2[/tex] s0

Answers

Answer:

The preferred p-value among the options offered is 0.001. The reason is because p-value represents the minimum probability of committing the type I error, that is, the probability of rejecting the null hypothesis, with the information contained in the sample, given that this hypothesis is true. The p-value of 0.001 is the lowest value proposed for this probability. Therefore, it supports more evidence that the null hypothesis is false.

Step-by-step explanation:

The preferred P-value among the options provided is 0.001.

0.001 is the preferred p-value simply because it shows the minimum probability of committing an error, it also implies that the probability of rejecting the null hypothesis based on the information presented in the sample, considering that the hypothesis is true.  

Further Explanation

Therefore, the p-value 0.001 is the lowest value proposed for this probability and it also corresponds to the sample of evidence that supports the alternative hypothesis which shows the method is effective.

Hypothesis testing refers to an act in statistics in which an analyst test the assumption as regards to a population parameter.

The methodology to be used by analysts is based on the nature of the data that are used and the purpose of the analysis

An analysts test a sample to accept or reject a null hypothesis. The outcome of the tests will reveal the analysis if his primary hypothesis is true or not. If the analysis of the tests is not true, it then means the analysts will have to formulate a new hypothesis and do the analysis again.

It implies the analysts will continue to repeat the process until the analysis shows the data hypothesis is true.

The slope of the given line passing through (7, 11) and (10, 20) is 3. Since parallel lines have equal slopes, the line passing through (4, 1) will also have a slope of 3. Plugging in the slope and point into the slope-intercept form, we find the equation of the line to be y = 3x - 11.

To find the equation of the line that passes through the point (4, 1) and is parallel to another line, we first need to determine the slope of the given line that passes through (7, 11) and (10, 20).

The slope of a line is found by taking the difference in the y-coordinates divided by the difference in the x-coordinates between two points on the line, which is often expressed as Δy/Δx or (y2-y1)/(x2-x1).

The slope of the line passing through (7, 11) and (10, 20) is calculated as follows:
Δy = 20 - 11 = 9

Δx = 10 - 7 = 3

Slope (m) = Δy/Δx = 9/3 = 3

Since parallel lines have the same slope, the line passing through (4, 1) will also have a slope of 3.

The equation of a line in slope-intercept form (y = mx + b) can then be used, where 'm' is the slope and 'b' is the y-intercept.

As we have the slope and a point on the line, we can substitute them into the equation to solve for 'b'.

The equation will look like this:
y = mx + b

1 = 3(4) + b

1 = 12 + b

b = 1 - 12

b = -11

The equation of the line that goes through (4, 1) and is parallel to the line through (7, 11) and (10, 20) is therefore y = 3x - 11.

Graph the parametric equation x = 2t y = t + 5, -2 ≤ t ≤ 3

Answers

Just fun I'm going to add something above the below.

You can write an equation for this without the parameter.

You have y=t+5 and x=2t.  If you multiply both sides of y=t+5 by 2 you should get 2y=2t+10 and guess what you can replace 2t with x since you have x=2t.  So you can write 2y=x+10 as your equation to represent the parametric version they have here.

This is a linear equation as our graph appears to be below.   Solve for y by dividing both sides by 2 gives you y=x/2  +5.  The slope is 1/2 and the y-intercept is 5.  If t is between -2 and 3 then x is between -4 and 6 since x is doubled t (inclusive here since we have those equal signs along with those inequalities).

So you could have just graph the line y=x/2+5 on the interval [tex]-4 \le x \le 6 [/tex]/

Anyways, I'm also going to look at this without the rewrite:

I'm going to make a table with 4 columns.  The first column is t.  The second is x(t), the third is y(t), and the fourth will be a list of points (x,y) our relation will go through).

t    |     x(t)        |     y(t)           |   (x,y)

------------------------------------------------------

-2       2(-2)=-4      -2+5=3          (-4,3)

-1        2(-1)=-2       -1+5=4           (-2,4)

0        2(0)=0         0+5=5           (0,5)

1         2(1)=2           1+5=6           (2,6)

2        2(2)=4          2+5=7          (4,7)

3        2(3)=6          3+5=8           (6,8)

Now I'm going to graph the points in the last column on a coordinate-plane.

The horizontal axis is your x-axis and the vertical axis is your y-axis. I did the x-axis going up or down by two's while the y-axis is going up and down only by one's.

In a survey, adults and children were asked whether they prefer hamburgers or pizza. The survey data are shown in the relative frequency table.

About 60% of adults prefer pizza.

Compare this with the percentage of children who prefer pizza.

Hamburgers Pizza Total
Adults 0.24 0.36 0.60
Children 0.11 0.29 0.40
Total 0.35 0.65 1.00

Select the true statement.

A. A smaller percentage of children (43%) prefer pizza.
B. A smaller percentage of children (30%) prefer pizza.
C. A greater percentage of children (about 70%) prefer pizza.
D. A greater percentage of children (64%) prefer pizza.

Answers

The 60% of adults who like pizza was found by dividing the adults who like pizza ( 0.36) by the total adults ( 0.60): 0.36 / 0.6 = 0.6 = 60%

To find the percent of children that like pizza divide 0.29 by 0.40:

0.29 / 0.40 = 0.725 = 72.5%, which is about 70%

The answer would be C. A greater percentage of children (about 70%) prefer pizza.

The percentage of children that prefer pizza are about 70%, which is Option(c) .

What is percentage?

A relative figure reflecting hundredth parts of any quantity is called a percentage.

How to calculate percentage?Determine the total amount of quantity.Find the amount of which you want to find percentage.Divide them both and multiply by 100

Children who like pizza = 0.29

Answers

Answer:

the three options i chose:

A. n and k are on plane A and s

C. p is the inteersection of n and g

D. those 3 lines are noncollinear

Answer:

The correct options are A, C and D.

Step-by-step explanation:

From the given figure it is clear that points N and K lie on the line f, and line f is the intersection line of plane A and S.

So, points N and K are on plane A and S. Option A is correct.

Points P and M lie on the line n, and line n is not the intersection line of plane B and S.

We clearly see that point M is not on the plane S.

So, option B is incorrect.

Point P is the intersection of line n and line g.

So, option C is correct.

Point M and P lie on line n and point P and Q lie on line g.

Three points are collinear if they are lie on a straight line.

Since points M, P and Q are not collinear, therefore they are noncollinear.

So, option D is correct.

Line d intersects plane A at point L.

So, option E is incorrect.

The ages of students in a school are normally distributed with a mean of 16 years and a standard deviation of 1 year. Using the empirical rule, approximately what percent of the students are between 14 and 18 years old?

Answers

Answer:

95% of students are between 14 and 18 years old

Step-by-step explanation:

First we calculate the Z-scores

We know the mean and the standard deviation.

The mean is:

[tex]\mu=16[/tex]

The standard deviation is:

[tex]\sigma=1[/tex]

The z-score formula is:

[tex]Z = \frac{x-\mu}{\sigma}[/tex]

For x=14 the Z-score is:

[tex]Z_{14}=\frac{14-16}{1}=-2[/tex]

For x=18 the Z-score is:

[tex]Z_{18}=\frac{18-16}{1}=2[/tex]

Then we look for the percentage of the data that is between [tex]-2 <Z <2[/tex] deviations from the mean.

According to the empirical rule 95% of the data is less than 2 standard deviations of the mean.  This means that 95% of students are between 14 and 18 years old

Jake wanted to measure the height of the Great Sphinx of Giza. He placed a mirror on the ground and then walked backwards until he was able to see the top of the statue in the mirror. If his eyes were 5.5 feet above the ground, how tall is the statue, to the nearest foot?

Answers

Answer:

65

Step-by-step explanation:

Final answer:

Jake measured the height of the Great Sphinx of Giza by using a mirror and the Law of Reflection. Doubling the height of the mirror gives us an approximation of the statue's height.

Explanation:

In order to measure the height of the Great Sphinx of Giza, Jake used the concept of the Law of Reflection.

He placed a mirror on the ground and walked backwards until he could see the top of the statue in the mirror.

If his eyes were 5.5 feet above the ground, the mirror's height would be equal to half the height of the statue.

Since Jake's eyes are at a height of 5.5 feet, the distance from the ground to the top of the mirror should also be 5.5 feet.

Therefore, the height of the Great Sphinx of Giza can be calculated by doubling the height of the mirror, which gives us 11 feet.

So, the approximate height of the statue is 11 feet.

Huixian needs to pack 171 pens, 63 pencil, and 27 erasers into identical bags so that each item is equally distributed among the gift bags. Find the largest number of gift bags that can be packed, and the number of each item in a gift bag

Answers

Answer:

87 gift bags

Step-by-step explanation:

Answer:

6 pens

2 pencils

1 eraser in each gift bag

Most number of Gift Bags = 27.

Step-by-step explanation:

There will be some bags left over. The limiting factor is the erasers. At most, you can have 27 erasers and therefore 27 gift bags.

171 pens: 171/27 = 6 (you have to round down). The number of pens left over is 9.

(27*6 = 162)    

171 - 162 = 9

63 Pencils: 63/27 = 2 pencils per gift bag. There will be

63 - 2*27

63 - 54

9 pencils will be left over.

NASA received three messages in a strange language from a distant planet. Scientists studied these messages and found that "Floos Beiling Hoomp" means "We come in peace" and "Moog Naline Floos" means "Peace, Love, and Freedom " and "Beiling Boog Vladi" means "In the last hour". What does "Hoomp" mean?

Answers

Answer:

Hoomp means "we come".

Step-by-step explanation:

"Floos Beiling Hoomp" means "We come in peace"

"Moog Naline Floos" means "Peace, Love, and Freedom "

"Beiling Boog Vladi" means "In the last hour"

Comparing 1st two statements, we get Floos means peace.

Comparing 1st and 3rd statements, we get Beiling means in

So, Hoomp is "we come".

Final answer:

"Hoomp" means "we come".

Explanation:

The question at hand involves deciphering the meaning of a word from messages in a strange language received from a distant planet.

By analyzing the given messages and their translations, we can determine the meaning of individual words through comparison and elimination.

Here's a step-by-step explanation:

"Floos Beiling Hoomp" means "We come in peace"."Moog Naline Floos" means "Peace, Love, and Freedom "."Beiling Boog Vladi" means "In the last hour".

Comparing the first and second statements, we understand that "Floos" means peace. From the first and third statements, we deduce "Beiling" means in.

Therefore, given its unique presence in the first statement, "Hoomp" logically translates to "we come".

This question illustrates the process of deciphering language through pattern recognition and comparative analysis, which is a fundamental aspect of linguistics and communication studies.
