I really need help with c,d and e
Zolol [24]

Answer:

Step-by-step explanation:

By using regression line calculator,

Equation of the line of best fit,

c). y = 0.74x + 0.03

Here, x = Number of pints

y = Weight in pounds

d). We have to find the weight of 10 pints of the blueberries,

By substituting x = 10 in the equation,

y = 0.74(10) + 0.03

y = 7.4 + 0.03

y = 7.43 pounds

e). If per pound cost of the blueberries = $2.25

By substituting y = 2.25 in the equation,

2.25 = 0.74x + 0.03

x = \frac{2.22}{0.74}

x = $3.00 per pound

Therefore, cost of 10 pounds blueberries = 3 × 10

                                                                     = $30

The height of a wooden pole, h, is equal to 20 feet. A taut wire is stretched from a point on the ground to the top of the pole.
kykrilka [37]

ANSWER

D. 25 feet

EXPLANATION

The height of the wall,h, the taut wire and the distance from the base of the pole to the point on the ground, formed a right triangle.

According to the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.

Let the hypotenuse ( the length of the ) taught wire be,l.

Then

{l}^{2}  =  {h}^{2}  +  {b}^{2}

{l}^{2}  =  {20}^{2}  +  {15}^{2}

{l}^{2}  =  400 + 225

{l}^{2}  =  625

l=  \sqrt{625}  = 25ft
