Answer:
B. 0.0918
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:
What proportion of batteries would be expected to last less than 16 hours?
This is the pvalue of Z when X = 16. So:
has a pvalue of 0.0918.
So the correct answer is:
B. 0.0918
Answer:
D
Step-by-step explanation:
c) representing data with a histogram is an example of data organization
Answer:
J. y > 3x + 5
Step-by-step explanation:
To convert the standard form equation into slope-intercept, we must make y isolated.
Step 1: Subtract 6x from both sides.
Step 2: Divide both sides by -2 and flip the inequality sign.
Therefore, the answer is J.

The domain lists all possible x values. In this case, x cannot be negative, so the lowest possible value is 0. X must be greater than or equal to 2 so that the value in the square root is at least 0. The answer is b.
