Answer:
0.0668
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 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:
Find the probability that the diameter of a selected bearing is greater than 129 millimeters.
This is 1 subtracted by the pvalue of Z when X = 129. So
has a pvalue of 0.9332
1 - 0.9332 = 0.0668
0.0668 = 6.68% probability that the diameter of a selected bearing is greater than 129 millimeters.
Answer:
The next 3 numbers to the given pattern of integers is -2,-1,-1,0,-1,1,-2 are 3,-5,8
Step-by-step explanation:
Given pattern of integers is -2,-1,-1,0,-1,1,-2
To find their next 3 numbers of the given pattern :
Let
Therefore
Therefore
Similarly we have , ,
The general form to the given pattern is
for
Therefore to find the
Put n=8 in
Put n=9 in
Put n=10 in
Therefore the next 3 numbers are 3,-5,8
Answer:
The zeros of the function are the numbers when put in the function will make it equal to zero
let y = 0
2x² +5x +2 = 0
(x + 2)(2x + 1) = 0
x = 2 , x = -1/2
The answer is option c.
