Answer:

C

Step-by-step explanation:

f'(x)=g(x) * (x^2-4)\\0=g(x)*(x^2-4)\\x={-2,2}\\f(-4) = -\\f(-2) = 0 \\f(0) = +\\f(2) = 0 \\f(4)= -\\\\

It decreases from negative infinity to -2, then increases, so x=-2 is a rel. min.

It increases from x=-2 to x=2, then decreases to infinity, so x=2 is a rel. max.

Scores on a test have a mean of 78.2 and 8 percent of the scores are above 89. The scores have a distribution that is approximat
anyanavicka [17]

Answer:

The standard deviation is 7.7

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 78.2

8 percent of the scores are above 89

This means that X = 89 has a pvalue of 1 - 0.08 = 0.92. So when Z = 89, Z = 1.405.

Z = \frac{X - \mu}{\sigma}

1.405 = \frac{89 - 78.2}{\sigma}

1.405\sigma = 10.8

\sigma = \frac{10.8}{1.405}

\sigma = 7.7

The standard deviation is 7.7
