Answer:
47.06% of the population has an IQ between 85 and 105.
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:
What percent of the population has an IQ between 85 and 105?
This is the pvalue of Z when X = 105 subtracted by the pvalue of Z when X = 85. So
X = 105
has a pvalue of 0.6293.
X = 85
has a pvalue of 0.1587
So 0.6293 - 0.1587 = 0.4706 = 47.06% of the population has an IQ between 85 and 105.
Answer:
6.16 is the answer
Step-by-step explanation:
3 + (.4^2 + 3)
3 + 3.16
6.16
Answer: c ≠ {-7, -3, 2, 5}
<u>Step-by-step explanation:</u>
=
restrictions:
c + 7 ≠ 0 c - 2 ≠ 0 c - 5 ≠ 0 c + 3 ≠ 0
c ≠ -7 c ≠ 2 c ≠ 5 c ≠ -3
Answer:
slope intercept form: y=mx+b
y+3=2(x+5)
step 1: use distributive property
y+3=2(x)+2(5)
y+3=2x+10
step 2: subtract 3 on both sides to make y by itself
y+3=2x+10
-3 -3
final answer: y=2x+7
