More properties of exponets 2y² times 3xy³ over 3x²y^4

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

You plan to purchase a bike costing $795. write an equation that could be used to find the amount m, that you must save per mont

Galina-37 [17]

Let
m-------> the amount that you must save per month

we know that
total cost of a bike=$795
5*m=795----------> equation that could be used to find the amount m
divide by 5 both sides
m=795/5
m=$159

the answer is
the equation that could be used to find the amount m is
5m=795

Answer:

30°, 150°

Step-by-step explanation:

You know the answer to this because you have memorized the short table of trig function values.

sin(θ) = 1/2 for θ = 30° and θ = 150°

The table shows the outputs, y, for different inputs, x: Input (x) 6 12 15 25 Output (y) 14 15 15 16 Part A: Do the data in this

cluponka [151]

Answer:

Part A: No it is not a function

Part B: The equation

Part C: x = 3

Step-by-step explanation:

Part A - The table:

Input (x) Output (y)

6 14

12 15

15 15

25 16

This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.

Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.

y = 7(6) -15

y = 42 - 15

y = 27

The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.

Part C: To find when y = 6, set it equal to 6 and solve for x.

6 = 7x - 15

21 = 7x

3 = x
