Answer:

A. 7

Step-by-step explanation:

If you were to solve for c by using d as 7 you would get:

c+7=40

c would then equal 33, which is greater than 30

Answer:

The correct option is;

C. The pattern is random, indicating a good fit for a linear model

Step-by-step explanation:

A graph that has the residuals (the difference between the value observed and the value expected (regression analysis) on the vertical axis and the variable that is not affected by the other variables (independent variable) on the x or horizontal axis is known as a residual plot

A linear regression model is suited in a situation where the points are dispersed randomly on both sides of the horizontal axis

Therefore, given that the first point is below the horizontal axis and the next point is above the horizontal axis, while the third and the fourth points are below the horizontal axis, the fifth, sixth, and seventh points are above the horizontal axis and the eighth point is below the horizontal axis, the points are random around the horizontal axis, indicating the suitability of a linear regression model.

Answer:

C. The pattern is random, indicating a good fit for a linear model.

Step-by-step explanation:

Took the test. It's 100% correct.

Answer:

C

Step-by-step explanation:

Because when you multiply 4³ × 4^4 = 16384

And 4^9 = 262144

(divide) 16384/262144 = .0625

.0625 = [tex]\frac{1}{16}[/tex]

[tex]\frac{1}{4^2}[/tex] = [tex]\frac{1}{16}[/tex]

because 4 * 4 = 16

Answer:

y= -1/3 + 13/3

Step-by-step explanation:

y-2=-1/3(x-7)

Use the distributive property to simplify the right side of the equation

y-2=(-1/3 * x) + (-1/3 * -7)

y-2=-1/3x + 7/3

Add 2 to both sides get the y by itself. 2 can be expressed as 6/3

(y-2) + 2=(-1/3x + 7/3) + 6/3

y= -1/3x + 13/3

Answer:

the answer =-8

Step-by-step explanation:

you subsitute -2 for x so its 4(-2) which is -8

Answer:

Given value x=-2, just substitute it to [tex]4^{x}[/tex]

= [tex]4^{-2}[/tex]   (this uses the property [tex]a^{-m}=\frac{1}{a^{m} }[/tex])

= This results in:

[tex]\frac{1}{4^{2} } = \frac{1}{16 }[/tex]

Answer:

82 - 60, 22 × 5, 111

Step-by-step explanation:

Solve the expressions:

Order the expressions from least to greatest:

Write out the expressions from least to greatest:

82 - 60, 22 × 5, 111

Answer:

-13

Step-by-step explanation:

first you will subsitute 5 for n in the  equation to get 3(5)-7m

next you will subsitute 4 for m in the equation to get 3(5)-7(4)

then solve: 3x5= 15

7x4= 28

15-28= -13

Answer:

The domain is continuous and the weight y of x identical hardcover books

Step-by-step explanation:

Discrete means non continuous data. This is continuous and equal so the domain is continuous.

Also, precipitation each week can vary so that won't work. Eating carrots each day can also vary so that doesn't work. The cost of an item can vary almost every day! So that is not true.

Therefore it is the last one, because it is identical and all of the coordinates make (1,3).

Hope this helps! :)

Answer:

8

Step-by-step explanation:

Answer: C

Step-by-step explanation:

The pair of angles created on the inner side of the parallel lines intersected by a transversal but on opposing sides of the transversal is known as an alternative interior angle. The correct option is C.

When two parallel lines are intersected by a transversal, the pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. These angles are always equal in measure.

The best statements BEST that proves ∠XWY ≌ ∠ZYW is that If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

Hence, the correct option is C.

Answer:

56:8:48

Step-by-step explanation:

1] add th eratio numbers together

7+1+4=12

2} write the ratio as fractions

7/12  1/12  4/12

3] use the formula (ration number/total number * number of sheeps)

a] 7/12 * 96 = 56

b] 1/12 * 96 = 8

c] 4/12 * 96 = 48

3] write your answer as a ration

7 : 1 : 4 = 56 : 8 : 48

Answer:

The answer is 56 : 8 : 32

Step-by-step explanation:

7 + 1 + 4 = 12

7/12 x 96 = 56

1/2 x 96 = 8

4/12 x 96 = 32

Answer:

298

Step-by-step explanation:

29.8 is 10 times as much as 298

The required proportion value is 2.98 which is equal to one-tenth of 29.8.

Given that,
To determine 29.8 is 10 times as much as a number.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number be x,

According to the question.
29.8 = x10
x = 29.8 / 10x
x = 2.98

Thus, the required proportion value is 2.98 which is equal to one-tenth of 29.8.

Answer:

the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.

Step-by-step explanation:

Answer:

the ability of an object or material to resume its normal shape after being stretched or compressed

Given:

She purchased adult ticket for herself and children tickets for her 2 boys.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

To find:

The expression to represent the total cost of the tickets Jenny purchased.

Solution:

Let x represent the number of adult ticket purchase

and y represent the number of child tickets purchase.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

Total cost = 39.99x + 19.99y

Therefore, the expression for total cost is 39.99x + 19.99y.

She purchased one adult ticket and 2 child tickets.

Substitute x=1 and y=2 in the above expression.

Total cost = 39.99(1) + 19.99(2)

               = 39.99 + 39.98

               = 79.97

Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

Answer:

y = -2/1x-2

Step-by-step explanation:

If each unit happens to be 1 then this will be correct, but it is hard to determine the equation without units.

Answer:

By plotting points A', B' and C' we can get the dilated image A'B'C'.

Step-by-step explanation:

Let the point P is origin (0, 0), segment AB lies on the x-axis and segment PC on the y-axis,

Coordinates of A, B and C will be (1, 0), (2, 0) and (0, 2).

When triangle ABC is dilated by a scale factor 4 about the origin,

Rule for dilation;

(x, y) → (4x, 4y)

New coordinates of the points A, B and C will be,

A(1, 0) → A'(4, 0)

B(-2, 0) → B'(-8, 0)

C(0, 2) → C'(0, 8)

Answer:

Correct

Step-by-step explanation:

New coordinates of the points A, B and C will be,

A(1, 0) → A'(4, 0)

B(-2, 0) → B'(-8, 0)

C(0, 2) → C'(0, 8)
