Answer: c) y = ln(5x) - 2

<u>Step-by-step explanation:</u>

$y=\dfrac{1}{5}e^{x+2}\\\\\text{Swap the x's and y's. Then solve for y:}\\\\x=\dfrac{1}{5}e^{y+2}\\\\\\\text{Multiply both sides by 5:}\\5x=e^{y+2}\\\\\\\text{Apply ln to both sides:}\\ln(5x)=ln\ e^{y+2}\\\\\text{Simplify:}\\ln(5x)=y+2\\\\\\\text{Subtract 2 from both sides:}\\ln(5x)-2=y$

Answer:

The answer is (B)

Step-by-step explanation:

Try out each of the situations. It can't be A, since the 0.9 is less than 1, so it has to be decreasing. This leaves only B and C. Since decreasing by 90 percent is the same as multiplying by 10 percent, the only possible answer left is B.

Hope this helps!

The weights of cockroaches living in a typical college dormitory are approximately distributed with a mean of 80 grams and a sta

Romashka [77]

Answer:

The percentage of cockroaches weighing between 77 grams and 83 grams is about 55%.

Step-by-step explanation:

Problems of normally distributed samples are 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:

$\mu = 80, \sigma = 4$
