Noah earned w dollars over the summer. Mai earned x dollars, which is y dollars
more than Noah did.

Answers

Answer 1
Final answer:

The question revolves around basic algebra and setting up an equality equation based on the given information. In this case, from the facts given, we can state Mai's earnings (x) in terms of Noah's earnings plus an additional amount (y), resulting in the equation x = w + y.

Explanation:

The subject of this problem is algebra, specifically involving variables and the concept of equality. In this problem, Noah earned an amount we will denote as w dollars over the summer. Mai, on the other hand, earned x dollars, and it's said that this is an amount of y dollars more than Noah did.

We can express Mai's earnings in terms of Noah's earnings by adding the extra amount to what Noah earned, which gives us the following equality equation:

x = w + y

This equation means that Mai's earnings (x) are equal to the sum of Noah's earnings (w) and the additional amount (y).

A regression model is used to forecast sales based on advertising dollars spent. The regression line is y=500+35x and the coefficient of determination is .90. Which is the best statement about this forecasting model?a. For every $35 spent on advertising, sales increase by $1.
b. Even if no money is spent on advertising, the company realizes $35 of sales.
c. The correlation between sales and advertising is positive.
d. The coefficient of correlation between sales and advertising is 0.81.

Answers

Answer:

The correlation between sales and advertising is positive.

Step-by-step explanation:

For every $35 spent on advertising, sales increase by $1

Is FALSE, since y = 500 + 35 x $35, sales increase more than $1

Even if no money is spent on advertising, the company realizes $35 of sales

Is FALSE, if no money is spent, the sales amount to $ 500 (when X = 0)

The coefficient of correlation between sales and advertising is 0.81

Is FALSE, since R² = 0.9. The coefficient of correlation = R = 0.94, not 0.81

This function f(x) has a domain of x = {-a, -b, a, b}.

In order, the x values are -a, -b, b, a.

In order, the f(x) values are 3c + 1, 2d - 5, 4d + 3, 6 - 2c.

Which values of c and d make this an even function?

a. c = -7 and d = 1/3
b. c = 5 and d = 1/3
c. c = -5 and d = -4
d. c = 1 and d = -4
e. c = -7 and d = -4​

Answers

Answer:

d. c = 1 and d = -4

Step-by-step explanation:

If a function is even, then f(-x) = f(x).  Graphically, this means it's symmetrical about the y-axis.

f(-a) = f(a)

3c + 1 = 6 − 2c

5c = 5

c = 1

f(-b) = f(b)

2d − 5 = 4d + 3

-2d = 8

d = -4

Therefore, c = 1 and d = -4.

(A) 4
(B) 6
(C) 8
(D) 10
(E) 12

Answers

Answer:

The answer is (C) 8

Step-by-step explanation:

First, let's calculate the length of the side of the square.

[tex]A_{square}=a^2[/tex], where [tex]a[/tex] is the length of the side. Now, let's try to build the square. First we need to find a point which distance from (0, 0) is 10. For this, we can use the distance formula in the plane:

[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex] which for [tex]x_1=0[/tex] and [tex]y_1 = 0[/tex] transforms as  [tex]d=\sqrt{(x_2)^2 + (y_2)^2}[/tex]. The first point we are looking for is connected to the origin and therefore, its components will form a right triangle in which, the Pythagoras theorem holds, see the first attached figure. Then, [tex]x_2[/tex], [tex]y_2[/tex] and 10 are a Pythagorean triple. From this, [tex]x_2= 6[/tex] or  [tex]x_2=8[/tex] while [tex]y_2= 6[/tex] or [tex]y_2=8[/tex]. This leads us with the set of coordinates:

[tex](\pm 6, \pm 8)[/tex] and [tex](\pm 8, \pm 6)[/tex].  (A)

The next step is to find the coordinates of points that lie on lines which are perpendicular to the lines that joins the origin of the coordinate system with the set of points given in (A):

Let's do this for the point (6, 8).

The equation of the line that join the point (6, 8) with the origin (0, 0) has the equation [tex]y = mx +n[/tex], however, we only need to find its slope in order to find a perpendicular line to it. Thus,

[tex]m = \frac{y_2-y_1}{x_2-x_1} \\m =  \frac{8-0}{6-0} \\m = 8/6[/tex]

Then, a perpendicular line has an slope [tex]m_{\bot} = -\frac{1}{m} = -\frac{6}{8}[/tex] (perpendicularity condition of two lines). With the equation of the slope of the perpendicular line and the given point (6, 8), together with the equation of the distance we can form a system of equations to find the coordinates of two points that lie on this perpendicular line.

[tex]m_{\bot}=\frac{6}{8} = \frac{8-y}{6-x}\\ 6(6-x)+8(8-y)=0[/tex]  (1)

[tex]d^2 = \sqrt{(y_o-y)^2+(x_o-x)^2} \\(10)^2=\sqrt{(8-y)^2+(6-x)^2}\\100 = \sqrt{(8-y)^2+(6-x)^2}[/tex]   (2)

This system has solutions in the coordinates (-2, 14) and (14, 2). Until here, we have three vertices of the square. Let's now find the fourth one in the same way we found the third one using the point (14,2). A line perpendicular to the line that joins the point (6, 8) and (14, 2) has an slope [tex]m = 8/6[/tex] based on the perpendicularity condition. Thus, we can form the system:

[tex]\frac{8}{6} =\frac{2-y}{14-x} \\8(14-x) - 6(2-y) = 0[/tex]  (1)

[tex]100 = \sqrt{(14-x)^2+(2-y)^2}[/tex]  (2)

with solution the coordinates (8, -6) and (20, 10). If you draw a line joining the coordinates (0, 0), (6, 8), (14, 2) and (8, -6) you will get one of the squares that fulfill the conditions of the problem. By repeating this process with the coordinates in (A), the following squares are found:

(0, 0), (6, 8), (14, 2), (8, -6)(0, 0), (8, 6), (14, -2), (6, -8)(0, 0), (-6, 8), (-14, 2), (-8, -6)(0, 0), (-8, 6), (-14, -2), (-6, -8)

Now, notice that the equation of distance between the two points separated a distance of 10 has the trivial solution [tex](\pm10, 0)[/tex] and  [tex](0, \pm10)[/tex]. By combining this points we get the following squares:

(0, 0), (10, 0), (10, 10), (0, 10)(0, 0), (0, 10), (-10, 10), (-10, 0)(0, 0), (-10, 0), (-10, -10), (0, -10)(0, 0), (0, -10), (-10, -10), (10, 0)

See the attached second attached figure. Therefore, 8 squares can be drawn  

It was reported that in​ 2004, the mean net worth of families in a certain region was ​$470.2 thousand and the median net worth was ​$92.3 thousand. Which measure of center do you think is more​ appropriate? Explain your answer.

Answers

Answer:

Median.

Step-by-step explanation:

We have been given that in​ 2004, the mean net worth of families in a certain region was ​$470.2 thousand and the median net worth was ​$92.3 thousand.

We know that mean and median of a symmetric data set is equal.

We also know that when mean of a data set is greater than median, then the data set has a very large valued outlier.

Since mean net wroth of families is approximately 5 times more than median net wroth of families, this means that some of the families has very high net worth as outliers.

Since the net worth of families has very large outliers, therefore, I would prefer median as the appropriate measure of center as median is not affected by outliers.

Final answer:

For the first problem, the diver's depth after diving 47 feet and then rising 12 feet is -35 feet or 35 feet below the surface. In the second problem, the temperature rose from -6°F to 7°F by noon.

Explanation:

Let's answer your mathematics problems one by one.

Problem 1:

A diver dives 47 ft below the surface of the water and then rises 12 ft. We can use addition by understanding that direction matters. A depth of 47 ft below the surface is represented as -47, while rising 12 ft means +12. So, the final depth could be represented mathematically as -47 + 12, which equals to -35 ft. It means the diver is 35 feet below the surface of the water.

Problem 2:

The temperature at 6 AM is -6°F. The temperature rises 13 degrees Fahrenheit by noon. The situation can be mathematically represented as -6 + 13. So, the temperature at noon would be 7°F.

Which polynomial is represented by the algebra tiles? 2x2 – 4x – 6 2x2 + 4x + 6 –2x2 – 4x – 6 –2x2 + 4x + 6

Answers

Final answer:

The algebra tile configuration described represents the polynomial 2x^2 - 4x - 6.

Explanation:

The algebra tile configuration you have described is representing the polynomial 2x2 - 4x - 6. This is deciphered as follows:

The 2 largest tiles labeled 'plus x squared' represent 2x2. For each of these tiles, the value is 'x squared' so two of them equals '2x squared'Four tiles half the size of the largest tiles are labeled 'negative x', thus representing -4x. If one large x tile represents 'x', then a half-size x tile represents '0.5x'. Since there are four such negative tiles, we get '4 * (-0.5x)' equals '-4x'.Six smallest tiles representing 'minus' account for the constant term of -6 since each of them is a quarter of the size of the largest tiles.

Sam and Amanda are brother and sister. Sam has twice as many brothers as sisters, and Amanda has five times as many brothers as sisters. How many boys and girls are there in this family?

Answers

Answer:Boys=5,girls =2

Step-by-step explanation:

Let b be the no of boys and g be the no of girls

Therefore

Sam has twice as many brothers as sisters

2g=b-1

b-2g=1--------------1

Amanda has five times as many brothers as sisters

5(g-1)=b

5g-b=5----------------2

using (1) & (2) we get

g=2

b=5

There are 5 boys and 2 girls in Sam and Amanda's family. We determined this by setting up equations based on the clues provided and solving for the number of brothers and sisters.

To solve the riddle of how many boys and girls are in Sam and Amanda's family, we must first establish two equations based on the information provided:

Sam has twice as many brothers as sisters. Let the number of brothers be 'b' and the number of sisters be 's'. Sam is a brother, so we do not count him. Thus, we have the equation b - 1 = 2s.Amanda has five times as many brothers as sisters. Since Amanda is a sister, we do not count her. So, we have the equation b = 5(s - 1).

Now we solve these two equations.

From the second equation, b = 5s - 5. Substituting this into the first equation:

(5s - 5) - 1 = 2s

Simplifying, we get:

5s - 6 = 2s

Now we solve for 's':

5s - 2s = 6

3s = 6

s = 2

There are 2 sisters. Substituting 's = 2' into b = 5(s - 1), we get:

b = 5(2 - 1)

b = 5

There are 5 brothers. But since we are including Sam in the total, there are 4 boys excluding Sam.

In conclusion, the family consists of 5 boys and 2 girls.

Sean plan to join a streaming music service. One plan is $20 down plus monthly payments of $10 a month. The second plan is $40 down and $8 a month. How many month with the total amount paid be the same for both companies? What would the amount be?

Answers

Answer:

10 months

Step-by-step explanation:

Let X represent the number of months

The cost equation for the first plan = $20 + 10x

The cost equation for the second plan =$ 40+8x

The number of months at which the cost for the two plans will be equal can be worked out by equating the costs for the two plans and then calculate the value of x.

Thus,

$20+10x = $40 +8x

        10x -8x =$40-$20  

            2x = $ 20

              x= 20/2

                 x= 10

Substituting X in each equation,

  $20 +$10(10) = $40 + $8(10)

   $ 20 +$100 =$40 +$80

       $120 =$120

Thus, the amount after ten months = $120

Two teams are distributing information booklets. Team A distributes 60% more boxes of booklets than Team B, but each box of Team A’s has 60% fewer booklets than each box of Team B’s. Which of the following could be the total number of booklets distributed by the two groups?

A. 2,000
B. 3,200
C. 4,100
D. 4,800
E. 4,900

Answers

Answer:

  C.  4,100

Step-by-step explanation:

"60% more" is represented by a multiplier of 1 + 0.60 = 1.60.

"60% fewer" is represented by a multiplier of 1 - 0.60 = 0.40.

__

Let b represent the number of booklets distributed by Team B. Then the number distributed by Team A is ...

  1.60 × (0.40b) . . . . 60% more boxes, each with 60% fewer booklets

  = 0.64b

Then the total distributed by both teams is ...

  b + 0.64b = 1.64b = (164/100)b = (41/25)b

The only answer choice that is a multiple of 41 is ...

  4,100 . . . choice C

__

For 4100 to be the number of booklets distributed by both teams, Team B will have distributed 2500 booklets, and Team A will have distributed 1600 booklets. Team A might have distributed 160 boxes of 100 booklets, while Team B might have distributed 100 boxes of 250 booklets.

Which property justifies this statement? If x=3, then x−3=0. Subtraction Property of Equality Division Property of Equality Reflexive Property of Equality Multiplication Property of Equality

Answers

Final answer:

The statement 'If x=3, then x−3=0' is justified by the Subtraction Property of Equality. This property allows you to subtract the same value from both sides of an equation while maintaining equality.

Explanation:

The statement 'If x=3, then x−3=0' is justified by the Subtraction Property of Equality. This property states that if you subtract the same number from both sides of an equation, the equation remains equal. So, in this case, you start with x=3 and then you subtract 3 from both sides to get x-3=0. It's also important to note that the other properties mentioned, Division, Reflexive, and Multiplication, aren't appropriate in this scenario because no division, reflexion or multiplication operation is being performed.

Dr. Cyril conducts a simple random sample of 500 men who became fathers for the first time in the past year. He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%. What is another term for the 4% value?

Answers

Answer:

The another term for the 4% value is : Margin of error

Step-by-step explanation:

Dr. Cyril conducts a simple random sample of 500 men.

He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.

Now, the another term for the 4% value is : Margin of error

Means the estimate of father being unsure about his ability would be between 19% and 27%.

When sample size is increased, the margin of error becomes smaller.

A women's hospital reported 212 deliveries during June. Two sets of twins were born. There were 215 obstetrical discharges; 214 births; four women had first-time C-sections; and three women had a repeat C-section. The C-section rate for September is 3.30 percent. True or false?

Answers

Impossible to know. Numbers provided on the statement are for June, though question is made for september. If, by any chance, question is not correctly stated, answer will be True

Step-by-step explanation:

According to the problem, there were 214 births. Seven of those 214 births were via C-section. Then: 100%*(7/214)=3.3%

It does not matter which births were natural, or C sectioned, as they are considered in the same group.
