3 + 3/4x > = 15
3/4x > = 15 - 3
3/4x > = 12
x > = 12 / (3/4)
x > = 12 * 4/3
x > = 48/3 = 16 sessions <==
================
-p - 4p >  -10
-5p > -10
p < -10/-5
p < 2 <===
===============
-3 - 6(4x + 6) > = 9
-3 - 24x - 36 > = 9
-24x - 39 > = 9
-24x > = 9 + 39
-24x > = 48
x < = -48/24
x < = -2 <===
=================
2x - 2 > = 10
2x > = 10 + 2
2x > = 12
x > = 12/2
x > = 6........so ur solution set is {6,7}

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

Approximately what percentage of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per​ microliter?

This is the pvalue of Z when X = 5.4 subtracted by the pvalue of Z when X = 4.2. So

X = 5.4

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

Z = \frac{5.4 - 4.577}{0.382}

Z = 2.15

Z = 2.15 has a pvalue of 0.9842

X = 4.2

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

Z = \frac{4.2 - 4.577}{0.382}

Z = -0.99

Z = -0.99 has a pvalue of 0.1611

0.9842 - 0.1611 = 0.8231

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