Answer:
The probability that x is less than 9.7 is 0.0069 = 0.69%
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:
The probability that x is less than 9.7 is _____.
This is the pvalue of Z when X = 9.7. So
has a pvalue of 0.0069
The probability that x is less than 9.7 is 0.0069 = 0.69%
<h3>Answer: Choice C is correct</h3>
Explanation:
We can think of the square in the middle of the four others as the floor
The surrounding four squares are the walls that fold upward.
The square at the very right side will then form the ceiling.
Side E and side L join at the top left edge.
