76/4=19 lb is weighht of 1 bushel of rye
19*8.5=161.5 lb
8.5 bushels of rye weigh 161.5 lb
Answer: 30
Step-by-step explanation: when you look at the x value of 9, the y value on the best fit line would be 30
Answer:
56.5 degrees
Step-by-step explanation:
Because complementary angles are when their sum is 90, you get the equation:
P + Q = 90
Since Q is 33.5,
P + 33.5 = 90
Subtracting 33.5 from both sides,
P = 56.5
Answer:
3.59% of the ball bearings will have diameters of 20.27 mm or more.
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 ball bearings will have diameters of 20.27 mm or more?
This is 1 subtracted by the pvalue of Z when X = 20.27. So



has a pvalue of 0.9641.
1-0.9641 = 0.0359
3.59% of the ball bearings will have diameters of 20.27 mm or more.
