Answer:
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
Step-by-step explanation:
When the distribution is normal, we use 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.
Manufacturing Ball bearings are manufactured with a mean diameter of 5 millimeters (mm).
This means that
With a standard deviation of 0.02 mm.
This means that
(a) What proportion of ball bearings has a diameter more than 5.03 mm
This is 1 subtracted by the pvalue of Z when X = 5.03. So
has a pvalue of 0.9332
1 - 0.9332 = 0.0668
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
Answer: 101.46 ounces in 3 liters
Step-by-step explanation:
To do this problem in the easiest way, you take your half liter and double your answer to make it one liter.
16.91 x 2= 33.82 ( 1 liter)
Now since you have one liter and you need 3 liters, all you do is triple your last answer to get 3 liters.
33.82 x 3= 101.46 ( 3 liters)
Answer:
13. 14. 15.
A.) 21 A.)-2 A.) 8
B.) 21 B.) 14 B.) 8
Step-by-step explanation:
13.
A.) 2(4)^2 - 11 = 21. B.) 2(-4)^2 - 11 = 21
* Note: if the power is a even number (2, 4, 6, and on), then the negative won't affect the answer and can be forgotten.
14.
A.)2squareroot16 - 10 = -2.
B.)2squareroot16 - 10 = 14
15.
|-3 - 8| + (-3) =8
|1/2 - 8| + 1/2 = 8
