Which r–value represents the strongest negative correlation?A. –0.7
B. –0.22
C. 0.38
D. 0.9

Answers

Answer 1
Answer: The best answer to the statistics question above would be letter A. The r-value that represents the strongest negative correlation among the given choices would be -0.7. This is because the magnitude of the correlation ranges from .7 to .9 which indicates a strong correlation. The negative sign connotes the negative relationship.

Answer:

A because you can divide 24 by 4 to get 6 and you can subtract 18 by 24 to get 6 so therefore your answer would be A, hope this helps!

Answer:

(24, 6)

Step-by-step explanation:

To find an ordered pair (x, y) that works for both rules, we need to check if the same value of y is obtained when applying both Rule 1 and Rule 2 to a given value of x. Let's evaluate each option:

1. Rule 1: Divide x by 4 to get y.

  - For (24, 6): 24 divided by 4 equals 6.

  - For (30, 12): 30 divided by 4 equals 7.5 (not an integer).

  - For (32, 8): 32 divided by 4 equals 8.

2. Rule 2: Subtract 18 from a to get y.

  - For (24, 6): 24 - 18 equals 6.

  - For (30, 12): 30 - 18 equals 12.

  - For (32, 8): 32 - 18 equals 14.

Based on the evaluation of both rules, the ordered pair (24, 6) works for both Rule 1 and Rule 2. So, the correct answer is:

(24, 6)

What is the coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin?​

Answers

The coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin is, (- 5, 1)

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The coordinate of the point H( -1, -5)

Now, The rule for the 90° clockwise rotation about the origin is,

(x, y) = (y, - x)

Hence, The coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin is,

(- 1, - 5) = (- 5, 1)

Emily is 280 miles away from home. She is traveling back at a rate of 40 miles per hour. Determine which graphs and which equation represents Emily’s distance from home, D, after Emily travels h hours.

Answers

The required equation for the distance is y = 280 - 40h and graph is shown below.

What is speed?

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S = D/T,

where S=speed, D=distance, T= time.

Given that,

Distance of Emily from her home = 280 miles,

The speed of Emily of coming back = 40 miles per hour.

In h hours, the distance covered by Emily = 40h

Let the remaining distance is y,

So the equation can be written as,

y = 280 - 40h.

The graph of the equation represented below.

Answer:

-40*h+280

Step-by-step explanation:

Let s define the function f which represents Emily's distance from home

at h = 0 Emily is 280 miles away from home

so f(0)=280

as she is traveling back at a rate of 40 miles per hour

f(h)=-40*h+280

the graph is below
