N(17+x)=34x-r solve for x

77julia77 [94]

Answer:

$x=\frac{-17n-r}{(n-34)}$

Step-by-step explanation:

Given:

$n(17+x)=34x-r$

Taking the terms of x to one side.

$17n+nx=34x-r\\$

$nx-34x=-17n-r\\\\x(n-34)=-17n-r\\\\x=\frac{-17n-r}{(n-34)}$

The value of x is:

$x=\frac{-17n-r}{(n-34)}$

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:

$\mu = 78.2$
