Cary earns $975 each month on his part-time job. How much money does he earn in a year

Answer:

Option B

Step-by-step explanation:

Given:

total No. of students liking peas= 78

total no. of male students= 100

total number of students= 200

no. of male students liking peas= 42

Now we need to find are liking peas and being male independent or dependent events

P(likes peas)= 78/00

                    =0.39

                    =39%

P(likes peas/male) = 42/100

                                = 42%

as the two probabilities are not equal the two events are dependent.

Hence option B is correct: Dependent;

since these probabilities are not equal, the events are dependent!

Answer:

B

Step-by-step explanation:

In the Dependent case  the following relation must be satisfied:

p(a|b) = p(a∩b)/p(b)

Or, in terms of this problem:

p(like peas|male) = p(like peas∩male)/p(male)

The probabilities of this events are:

p(like peas|male) = 42/100 = 42%

p(like peas∩male) = 42/200 = 21%

p(male) = 100/200 = 50%

Therefore, the events are dependent

In the Independent case  the following relation must be satisfied:

p(a|b) = p(a)

or

p(like peas|male) = p(like peas)

p(like peas) = 78/200 = 39%

The equation is not satisfied.

Answer:

2.5 gallons

Step-by-step explanation:

We need to go 100 miles

Write the proportion

Picking a point on the graph (40 miles, 1 gallon)

100 miles         40 miles

-------------- = -------------

x gallons         1 gallon

Using cross products

100 * 1 = 40 *x

Divide each side by 40

100/40 = 40x/4

2.5 =x

We need 2.5 gallons to go 100 miles

Answer: Based on the graph, the car requires 2.5 gallons of fuel to travel 100 miles.

Look at the picture below for help. The blue dot represents were the two points meet. We are trying to figure out how many gallons are for the 100 miles, 100 miles would be on the side that says distance (miles). That is were you start. Find point 100 on the distance (miles) side and just draw a straight line, stopping when you hit the black line on the graph. Once done, draw another line going straight down from the black line, and you get your answer of 2.5

We have the following inequality:

7 − 9x − (x + 12) ≤ 25

Solving the inequation, we have:

7 − 9x − x - 12 ≤ 25

-10x ≤ 30

-x ≤ 3

x≥-3

Therefore the result is option A) x greater than or equal to −3

Answer:

B.

Step-by-step explanation:

7-9x - (x+12) ≤ 25

7 - 9x - x - 12 ≤ 25

-10x - 5 ≤ 25

-10x ≤ 25 +5

x ≥ 30/-10

x ≥ -3.

So, the incorrect answer is B.

Answer:

Isolate the variables in all cases. Note the equal sign, what you do to one side, you do to the other.

a) 3x = 18

Isolate the variable, x. Divide 3 from both sides:

(3x)/3 = (18)/3

x = 18/3

x = 6

b) 2x = 9

Isolate the variable, x. Divide 2 from both sides:

(2x)/2 = (9)/2

x = 9/2

x = 4.5

c) (x/5) = 7

Isolate the variable, x. Multiply 5 to both sides:

(x/5)(5) = (7)(5)

x = 7 * 5

x = 35

d) x/2 = 6.5

Isolate the variable, x. Multiply 2 to both sides:

(x/2)(2) = (6.5)(2)

x = 6.5 * 2

x = 13

Answer:

y^18

Step-by-step explanation:

(y^2)^5 x y^8

Assuming the x is multiplication

We know (a^b)^c = a^(b*c)

(y^2)^5 = y^(2*5) = y^10

We are multiplying this by y^8

We know a^b * a^c = a^(b+c)

y^10* y^8 = y^(10+8) = y^18

Assuming the x is a variable

We know (a^b)^c = a^(b*c)

(y^2)^5 = y^(2*5) = y^10

We are multiplying this by y^8

We know a^b * a^c = a^(b+c)

y^10* y^8 = y^(10+8) = y^18

This is multiplies by x

10 ≥ ⅛c + ¼d

Step-by-step explanation:

They budgeted up to 10 gallons of water, meaning that it CANNOT exceed 10. When turned around, you will see that everything is less than or equal to 10.

I am joyous to assist you anytime.

Complete question:

A small kennel has budgeted to provide 10 gallons of water for its animals. Each cat receive one eight of a gallon per day and each dog receives one fourth of a gallon per day . Which inequality correctly represent the scenario.

a. 10 < -1/8c - 1/4d

b.  10 ≤  1/8c + 1/4d

c  10 ≥ -1/8c - 1/4d

d. 10 ≥ 1/8c + 1/4d

Answer:

d. 10 ≥ 1/8c + 1/4d

Step-by-step explanation:

The kennel was budgeted to provide 10 gallons of water for its animals. The cat receives  1/8 of a gallon per day and each dog receive 1/4 of a gallon per day.

Since 10 gallons was budgeted for the animals the sum of the a gallon per day for the cat and dog will most likely not exceed 10 gallons. The animals will most likely consume less than the budgeted value or equals to the budgeted value.    

note that the sum of 1/8 of a gallon  for the cat and 1/4 of a gallon for the dog should be either less than 10 or equals to 10. This means  10 ≥ 1/8c + 1/4d .

Answer:

1)all numbers less than -5 and greater than 5

Step-by-step explanation:

We are given

x<-5

and

x>5

So

Looking at both the inequalities one by one, The solution will consist of all the numbers that are less than -5 and greater than 5. The numbers between -5 and 5 will be excluded from the solution..

Hence,

1)all numbers less than -5 and greater than 5

is correct ..

The intersection of the sets {X|X<-5} and {x|x>5}, which represents numbers that fulfill both conditions, results in no real numbers, or the empty set.

The solution set of the given intersection of the two sets {X|X<-5} and {x|x>5} is defined as the set of numbers that fulfill both conditions: numbers less than -5 and numbers greater than 5.

However, there are no real numbers that can be both less than -5 and greater than 5 at the same time. Therefore, when these two sets intersect, the result is an empty set.

Answer:

d (-5,0)

Step-by-step explanation:

x-coordinate moves a point left or right from the origin.

y-coordinate moves a point down or up form the origin.

So we don't want any down or up, so we want y to be 0.

If a point is located on the x-axis, then the y-coordinate is 0.  

d is the only point that sits on the x-axis. I know this because it's y-coordinate is 0.

Answer:

m∠1 = 50°

m∠2 =  130°

Step-by-step explanation:

The measure of the angle formed by 2 chords  that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs.

m∠1 = (53+47)/2 = 50°

m∠1 + m∠2 = 180°   ⇒  m∠2 = 180 - m∠1 = 180 - 50 = 130°

The measure of angle 2 (θ2) is given as 312°. To determine the measure of angle 1 (θ1), additional information or context is needed as it is not provided directly in the question or accompanying information.

The question seems to be about finding the measures of angles angle 1 (θ1) and angle 2 (θ2) in a physics context, possibly related to momentum or forces. Given that Ø2 is provided as 312°, we can infer that this is the measurement of angle 2 (θ2). This angle is said to be in the fourth quadrant, which is consistent with the positive counterclockwise definition of angle measurement. For the measure of angle 1 (θ1), there's not enough direct information provided in the question or the reference information to determine its measure. More context or additional data would be necessary to solve for θ1. If the scenario is about a momentum conservation problem, the relationship between angles might be set by the conservation laws for linear momentum in the x and y directions. However, without additional information or clarification from the student's initial query, we would only be speculating on the measure of θ1.

3.14×5^2= 78.4

Answer:

29.97 square feet

Step-by-step explanation:

Given

The length of rectangle = 9 ft

The width of rectangle = 40 in

We have to bring the length and width in same unit. As the area is required in square feet so we will convert width in feet

The width will be divided by 12 to be onverted into feet

So,

Width = 40/12 = 3.33 feet

Now

Area = Length * width

= 9 * 3.33

= 29.97 square feet ..

Answer:

Area of rectangle = 30 square feet

Step-by-step explanation:

We are given that a rectangle is 9 feet long and 40 inches wide and we are to find its area in square feet.

For this, we will covert the width of the rectangle to feet and then find the area.

We know that:

[tex]\frac{1 foot}{x} =\frac{12 inches}{40}\\x=3.3 feet[/tex]

So width in feet is 3.3 feet.

Area of rectangle = [tex]9 \times 3.33[/tex] = 30 square feet

[tex]f^{-1}[/tex] (x ) = [tex]\frac{x+6}{5}[/tex]

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject, that is

y = 5x - 6 ( add 6 to both sides )

y + 6 = 5x ( divide both sides by 5 )

x = [tex]\frac{y+6}{5}[/tex]

Change y back into terms of x

[tex]f^{-1}[/tex] (x ) = [tex]\frac{x+6}{5}[/tex]

Answer:

y = - 10x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here slope m = - 10, hence

y = - 10x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = 10 + c ⇒ c = 4 - 10 = - 6

y = - 10x - 6 ← equation of line

r = 10.37% or 0.1037

t = 5:

We have the formula Amt= [tex]p(1+r)^{t}[/tex]

Amt =[tex]1200000(1+0.1037)^{5}[/tex]

The measure of angle A is 51 degrees

Answer:

The measure of an angle A=[tex]1^{\circ}[/tex].

Step-by-step explanation:

We are given that an angle [tex]95^{\circ}[/tex] and two sides are 7  in and 9 in in a given figure.

We have to find the value of measurement of angle A.

To find the measurement of angle A we apply sine law.

Sine law:[tex]\frac{a}{sin \alpha}=\frac{b}{sin\beta}=\frac{c}{sin \gamma}[/tex]

Where  side a is opposite to angle [tex]\alpha[/tex]

Side b is opposite to angle [tex]\beta[/tex]

Side c is opposite to angle[tex] \gamma[/tex]

We are given an angle 95 degrees and opposite side of given angle is 9 in and the angle A is opposite to side 7 in.

Substituting the values then we get

[tex]\frac{9}{sin 95^{\circ}}=\frac{7}{sin A}[/tex]

[tex]\frac{9}{0.683}=\frac{7}{sin A}[/tex]

[tex] sin A=\frac{7\times 0.683}{9}[/tex]

[tex] sin A=\frac{4.781}{9}=\frac{4781}{9000}[/tex]

[tex] sin A=0.531[/tex]

[tex] A= sin^{-1}(0.531)[/tex]

[tex] A=0.56^{\circ}[/tex]

[tex] A= 1^{\circ}[/tex]

Hence, the measure of an angle A=[tex]1^{\circ}[/tex].

Answer:

(5/2 ,  3/2)

or

(2.5  , 1.5)

(These are the same point; just one is in fraction form and the other in decimal)

Step-by-step explanation:

I could be wrong but I think you want to solve the system

x+y=4

x-y=1

The cool thing about this system it is already set up for elimination (some people call it linear combination).  This means when you add the equations together, a variable will get eliminated allowing you to solve for the other.

x+y=4

x-y=1

----------Add equations.

2x+0=5

2x    =5

 x     =5/2

 x     =2.5

So plug in your x into either one of the equations and solve for y.

x+y=4

2.5+y=4

y=4-2.5

y=1.5

So the solution is (2.5 , 1.5)  or (5/2, 3/2).

which is then equal to -5

Answer:

In the explanation:

Step-by-step explanation:

f(-10) means we need to find the piece so that x is also satisfied.

So we have x=-10 here.  Which of your pieces satisfy that?

Well [tex]-10 \le -5[/tex] so the first piece.  

[tex]f(-10)=2(-10)+1=-20+1=-19[/tex].

f(2) means we find the piece so that x is also satisfied.

So we have x=2 here. Which of your pieces satisfy that?

Well [tex]-5<2<5[/tex] so the second piece.

[tex]f(2)=(-2)^2=4[/tex].

f(-5) means we use the piece that satisfied x=-5.

-5 equals -5 and the equals -5 part is included in the first piece.

[tex]f(-5)=2(-5)+1=-10+1=-9[/tex]

f(-1) means use the piece so that x=-1 is satisfied.

-1 is between -5 and 5 so use [tex]x^2[/tex]

[tex]f(-1)=(-1)^2=1[/tex]

f(8) means use the piece so that x=8 is satisfied.

9 is greater than 5 so we use the third piece.

[tex]f(8)=3-8=-5[/tex]

It looks like you have all the answers and you are trying to figure out why.

Let's do another problem.

What piece would you use if I asked you to evaluate:

f(-2)?

x=-2 satisfies the [tex]-5<x<5[/tex] so we use the [tex]x^2[/tex]

[tex]f(-2)=(-2)^2=4[/tex]

f(-6)?

x=-6 satisfies the [tex]x \le -5[/tex] so we use the [tex]2x+1[/tex]

[tex]f(-6)=2(-6)+1=-12+1=-11[/tex]

f(7)?

x=7 satisfies [tex]x \ge 5[/tex] so we use [tex]3-x[/tex]

[tex]f(7)=3-7=-4[/tex]

I will post the answers here after you had time to think about it.
