Answer:

<h2>NO SOLUTION</h2>

Step-by-step explanation:

$-25x+175>225\ \wedge\ 5x-83>-73\\---------------\\-25x+175>225\qquad\text{subtract 175 from both sides}\\\\-25x>50\qquad\text{change the signs}\\\\25x10\qquad\text{divide both sides by 5}\\\\\boxed{x>2}\\\\\text{We have}\ x2,\\ \text{therefore this system of inequalities have no solution.}$

$\text{We have inequalities connected by the word "and"},\\\text{ therefore x must be the solution of both the first}\\\text{ and the second inequality.}$

Thirty-three college freshmen were randomly selected for an on-campus survey at their university. The participants' mean GPA was

Ivan

Answer: $\pm0.1706$

Step-by-step explanation:

Given : Sample size : n= 33

Critical value for significance level of $\alpha:0.05$ : $z_{\alpha/2}= 1.96$

Sample mean : $\overline{x}=2.5$

Standard deviation : $\sigma= 0.5$

We assume that this is a normal distribution.

Margin of error : $E=\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $E=\pm (1.96)\dfrac{0.5}{\sqrt{33}}=\pm0.170596102837\approx\pm0.1706$

Hence, the margin of error is $\pm0.1706$
