Answer:
9x 2 equals 18. 72 divided by 18 is 4. So the answer is 4.
Step-by-step explanation:
Answer:
Option B, x = 20
Step-by-step explanation:
<u>Step 1: Make an equation</u>
The values of 65 degrees and (3x + 5) are equal.
65 = 3x + 5
<u>Step 2: Subtract 5 from both sides</u>
65 - 5 = 3x + 5 - 5
60 = 3x
<u>Step 3: Divide both sides by 3</u>
60 / 3 = 3x / 3
<em>20 = x</em>

Answer: Option B, x = 20
Answer:
The area of the shaded region is 0.9082.
Step-by-step explanation:
Problems of normally distributed samples can be 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, which is the area of the shaded region, 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:

Area of the shaded region:
pvalue of Z



has a pvalue of 0.9082
So
The area of the shaded region is 0.9082.
Answer:
x = 3
Step-by-step explanation:
9x - 5 = 22
Add 5 to both sides
9x = 27
Divide both sides by 9
x = 3
