Perimeter = 2w + 2l

Since its a square, the length and width are equal therefore:

2(s + 3) + 2(s + 3) = Perimeter

You can simplify this into a variety of ways:

1. 4(s + 3)
2. 2s + 6 + 2s + 6
3. 4s + 12

Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a

serg [7]

Answer:

82.31% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter

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:

$\mu = 4.577, \sigma = 0.382$
