Answer:

x = 7 units

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

5 cm 3 cm

------------------ = ------------------------

(40 + 5) cm (3 + 2x + 10) cm

This simplifies to:

5 3

-------- = -----------

45 2x + 13

Solve for x. Cross-multiplying, we get:

10x + 65 = 135, or x = 7

So x = 7 units.

Our model is

$\hat{y} = 2.17 x + -114.05$

When x=82 degrees F,

$\hat{y} = 2.17 (82) + -114.05 = 63.89$

We round up to

Answer: 64 bags

Not sure why it says y^=34 in the question; I'm ignoring that.

The residual is the difference between the actual y and the predicted y,

$e = y - \hat{y} = 66 - 64 = 2$

Answer:

h = 2.25 m

Step-by-step explanation:

Given:

Speed = v = 12 ft/sec

Acceleration due to gravity = g = 32 ft/sec²

Required:

Height = h = ?

Formula:

v = $\sqrt{2gh}$

Solution:

For h, the formula will be:

=> h = $\frac{v^2}{2g}$

=> h = $\frac{(12)^2}{2(32)}$

=> h = $\frac{144}{64}$

=> h = 2.25 m
