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:
168
Step-by-step explanation:
You multiply all the number together.
Answer:
1,344 square inches
Step-by-step explanation:
First, determine the faces that you have to find the areas of! In this situation, you need to find the areas of two trapezoids and four rectangles.
Finding the area of a trapezoid is pretty straightforward! Simply find the average of the two bases and multiply that by the height. ((5+15)/2)*12 should equal the area of one trapezoid. Because they're both the same trapezoid, you can multiply this area by two in order to get the area of both. This will get you 240.
Now, find the area of each of the rectangles by multiplying their individual bases and heights together. You'll find them to be 312, 360, 120, and 312.
Lastly, add all the areas together to get the total surface area.
Answer:
57.04
Step-by-step explanation:
2 x 1.2 = 2.4
2.4 x 2.4 = 5.76
5.76 + 9 = 14.76
14.76 x 2 = 29.52
5.76 + 8 = 13.76
13.76 x 2 = 27.52
29.52 + 27.52 = 57.04
Yes. It is a wise financial decision because lots of places can be up to 1,000 a month. You would be taking 1,000 out of your check. Giving you only $1,000 for grocerys, car payment, insurence, etc. Only paying $500 can lead to you having more money for other thing. Maybe you wanna go out with your friends, ok? You are spending $1,000 on your apartment and don't have the money, as to where if you are only spending $500, you would have the money to go out and have fun. So, it is a very wise financial decision.
Hope this helped!
