Associativity means
(A+B)+C=A+(B+C)=A+B+C
Substitute A=9, B=8, C=32 to apply to this problem.
Answer:
c
Step-by-step explanation:
-2.25*3 = 6.75 decreased (since negative)
Answer:
0.2514 = 25.14% probability that the diameter of a selected bearing is greater than 85 millimeters.
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 question, we have that:

Find the probability that the diameter of a selected bearing is greater than 85 millimeters.
This is 1 subtracted by the pvalue of Z when X = 85. Then



has a pvalue of 0.7486.
1 - 0.7486 = 0.2514
0.2514 = 25.14% probability that the diameter of a selected bearing is greater than 85 millimeters.
C. million or 500,000,000
d.thousands or 30,000
and the first one is good and the second one for the million you wrote all the zeros right so it should look like 80,000,000
Step-by-step explanation:
8 the answer is 8 just think of quarters
