Answer:
A. 16%
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:
Which of the following gives the probability that a randomly selected woman has a height of greater than 68 inches?
This is 1 subtracted by the pvalue of Z when X = 68. So
has a pvalue of 0.84.
1 - 0.84 = 0.16
So the correct answer is:
A. 16%
128 adult tickets were sold
(1/3) m - 7 = 5
(1/3) m - 7 + 7= 5 + 7 ⇒⇒⇒ edit 7 to both sides
(1/3) m = 12
3 * (1/3) m = 12 * 3 ⇒⇒⇒ multiply both sides by 3
∴ m = 36
Answer:
x^2 - 25 ✔
Step-by-step explanation:
(x+5)(x-5)
x(x-5) +5(x-5)
x^2 - 5x + 5x - 25
x^2 - 25

<h2><u>
If 7=8 there would be 1 pineapple in the ocean.</u></h2>
Step-by-step explanation:
<em>I think this would be the reasoning because if there is 1 pineapple in the ocean because Spongebob lives in a pineapple under the sea and he seems to be the only one in Bikini Bottom to live in a pineapple. Therefore, there is only one pineapple, and Spongebob is happy.</em>
