Leah is 24 and her cousin is 12. Since 24 is double of 12, thats your answer and it makes the most sense.

The graph represents function 1, and the equation represents function 2: Function 1 A coordinate plane graph is shown. A horizon

Katena32 [7]

The horizontal line at y=4 doesn't have any slope, so the answer should be relatively easy to find. It's just the slope of Function 2.

y = 8x + 12 is the function for Function 2. 8x is the important part.

So the rate of change differing from both functions is 8.

Suppose that the regression for predicting weight (in pounds) from Height (in Select one answer inches) is given by Weight =-115

Nutka1998 [239]

Answer:

Option D) I and II only

Step-by-step explanation:

We are given the following in the question:

Regression equation:

$w = -115 + 3.6h$

where w is the weight in pounds and h is the height in inches.

Since the weight depends on height, height becomes the independent variable and weight becomes the dependent variable.

I. A person who is 61 inches tall will weigh 104.6 pounds

When h = 61,

$w = -115 + 3.6(61) = 104.6$

Thus, the given statement is true.

II. For every additional inch of height, the predicted weight will increase, on average, by 3.6 pounds.

If the height increases by 1 unit, then,

$w(h+1) - w(h) = -115 + 3.6(h+1) - (-115 + 3.6(h))\\w(h+1) - w(h) = 3.6(h+1-h)\\w(h+1) - w(h) = 3.6$

Thus, the given statement is correct.

III. The correlation between weight and height is negative.

No, the given statement is not correct as with increase in height the weight increases and with decrease in height the weight decreases.

Thus, the correct answer is

Option D) I and II only

How do you find the height of a parallelogram if you know the base and area?

ludmilkaskok [199]

You divide the area by the base because A = bh, so you would use the algebraic expression (A/B)=H

Step-by-step explanation:

3 liters = 3000 milliliters

3L/10 or 3000ml/10 = 0.3 L or 300 ml
