What is the surface area of this right rectangular prism?
tiny-mole [99]

Answer:

32 yd^2

Step-by-step explanation:

Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.

This prism has 6 surfaces:

  1. Front: 3 x 2.66 = 8
  2. Back: 3 x 2.66 = 8
  3. Top: 3 x 1.33 = 4
  4. Bottom: 3 x 1.33 = 4
  5. Side: 1.33 x 2.66 = 4
  6. Side: 1.33 x 2.66 = 4

Total SA: 8(2) + 4(4) = <u>32 yd^2</u>

The probability of making a type II error is given by one minus the power of the hypothesis test.

In general for the alternative hypothesis , H_a:\mu\ \textgreater \ \mu_0

The power of a hypothesis test is given by:

\beta(\mu')=\phi\left(X \ \textless \  \mu_0+z_{1-\alpha}\frac{\sigma}{\sqrt{n}}|\mu'\right) \\  \\ =\phi\left(z_{1-\alpha}+\frac{\mu_0-\mu'}{\sigma/\sqrt{n}}\right) =\phi\left(z_{1-0.01}+\frac{30000-31000}{1500/\sqrt{16}}\right) \\  \\ =\phi\left(z_{0.99}+\frac{-1000}{1500/4}\right)=\phi\left(2.33-\frac{1000}{375}\right)=\phi(2.33-2.667) \\  \\\phi(-0.33)=0.3682

The probability of <span>making a type ii error when μ = 31,000 is given by

1-\beta(\mu')=1-0.3682 \\  \\ =0.6318</span>

ANEK [815]

Answer:

A. 20t² + 9t - 20

Step-by-step explanation:

(5t × 4t) + (5t × 5) - (4 × 4t) - (4 × 5)

= 20t² + (25t - 16t) - 20

= <u>20t² + 9t - 20</u> (A)
