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%
Answer:
- <u><em>Second option: the graph approaches 0 as x approaches infinity.</em></u>
Explanation:
The function f(x) is:
- When x approach infinity the term x² grows rapidly (more rapid than x), thus 1 - x², which is in the denominator will decrease, become a large negative more rapid than the x in the numerator. Thus you can expect that the function approaches zero.
To prove that in a more analytical way, divide both numerator and denominator by x and simplifiy:

hope this helps
have a good day :)
Step-by-step explanation:
I have 2 brothers and 2 sisters. My mother said if we were good, we would get our allowance. The 5 of us were playing catch in the house. When I tried to catch the ball, I accidentally knocked over my mom's decorative vase and it broke. Needless to say that we did not get our allowance. It cost $50 to replace the vase. My brothers and sisters agreed to share the cost. How much did each person earn?
It's kind of silly, but that's all I can think of.
