Answer:

u = $\frac{r}{w+q}$

Step-by-step explanation:

Given

uw + uq = r ← factor out u from each term on the left side

u(w + q) = r ← divide both sides by (w + q)

u = $\frac{r}{w+q}$

Answer: u= $\frac{r}{w+q}$

Step-by-step explanation:

uw + uq = r To solve for u factor the left side to eliminate the other variables.

u ( w + q) = r Now divide both sides by w+q

u = $\frac{r}{w+q}$

Answer:

7.64% probability that they spend less than $160 on back-to-college electronics

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:

$\mu = 237, \sigma = 54$
