N = 36 = 24.6 s = 12 h0: ? 20 ha: ? &gt; 20 refer to exhibit 9-1. the test statistic is
solong [7]
To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ),  and population mean (μ), we can use

z-score = \frac{x - \mu }{\sigma / \sqrt{n}}

Given that n = 36, x = 24.6, μ = 20, and σ = 12,

z-score = \frac{24.6 - 20}{12 / \sqrt{36}}
z-score = \frac{4.6}{2} = 2.3

From this, we see that the test statistic is 2.3.

Answer: 2.3

Dvinal [7]

SOLUTION:

Step 1:

In this question, we are given the following:

What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?

A. (-3.5, 1)

B. (1.5,-4)

C. (-4,1.5)

D. (1.-3.5)

Step 2:

The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

\begin{gathered} (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ =\text{ (}\frac{-4+7}{2},\frac{-3+(-5)}{2}) \\ =\text{ (}\frac{3}{2},\frac{-8}{2}) \\  \end{gathered}

=\text{ (1. 5 , -4 ) --- OPTION B}

jek_recluse [69]

Answer:

3x² + 13x + 4

Step-by-step explanation:

3x³ - 2x² - 61x - 20

3x³ - 15x² + 13x² - 65x + 4x - 20

[3x²(x - 5) + 13x(x - 5) + 4(x - 5)]/(x-5)

3x² + 13x + 4
