The p-value falls between 0.025 and 0.05 is my guess, since we have t = -1.45 in 25 observations. The test of H0 against Ha show that μ = 7.2 and μ < 7.2 means μ = μ (7.2 = 7.2).

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 8x + 5

g(x) = 7x - 2

<u>Step 2: Find f(g(4))</u>

  1. Substitute in <em>x</em> [Function g(x)]:                                                                         g(4) = 7(4) - 2
  2. Multiply:                                                                                                             g(4) = 28 - 2
  3. Subtract:                                                                                                            g(4) = 26
  4. Substitute in function value [Function f(x)]:                                                      f(g(4)) = 8(26) + 5
  5. Multiply:                                                                                                              f(g(4)) = 208 + 5
  6. Add:                                                                                                                   f(g(4)) = 213

Find the length of side BC.<br> Give your answer to 3 significant figures
Y_Kistochka [10]

Answer:

\huge\boxed{\sf BC = 19.4 \ cm}

Step-by-step explanation:

<h3><u>Given:</u></h3>

θ = 71°

Adjacent = AB = 6.3 cm

<h3><u>Required:</u></h3>

Hypotenuse = BC = ?

We will use the trigonometric ratio of cos.

\displaystyle cos \theta = \frac{Adjacent}{Hypotenuse} \\\\cos \ 71 = \frac{6.3}{BC} \\\\0.33 = \frac{6.3}{BC} \\\\BC =\frac{6.3}{0.33} \\\\\boxed{BC = 19.4 \ cm}\\\\\rule[225]{225}{2}
