Answer:
-4 and 6
Step-by-step explanation:
Answer:
512 ounces
Step-by-step explanation:
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
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
and standard deviation
, the zscore of a measure X is given by:

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:

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



has a pvalue of 0.9842
X = 4.2



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
