Answer:

The correct option is C) 21.1 and 0.68

Step-by-step explanation:

Consider the provided information.

The mean composite score was 21.1 with a standard deviation of 4.8. The ACT composite score ranges from 1 to 36, with higher scores indicating greater achievement in high school.

Therefore μ = 21.1 and σ = 4.8

It is given that the sample of 50 students;

Thus, sample size ( n ) = 50

According to the central limit theorem,

$\mu_{\bar x}=\mu\ and \ \sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}$

Therefore

$\mu_{\bar x}=21.1$

$\sigma_{\bar x}=\frac{4.8}{\sqrt{50}}$

$\sigma_{\bar x}=0.68$

Hence, the correct option is C) 21.1 and 0.68

multiply both sides of the equation by 3.

2x+3y=9

move variable to the right side and change its sign

2x=9-3y

divide both sides of the equation by 2

x=9/2-3/2y
