Answer:
Hip breadths less than or equal to 16.1 in. includes 90% of the males.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 14.5
Standard Deviation, σ = 1.2
We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.
Formula:
![z_{score} = \displaystyle\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z_%7Bscore%7D%20%3D%20%5Cdisplaystyle%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
We have to find the value of x such that the probability is 0.10.
P(X > x)
Calculation the value from standard normal z table, we have,
![P(z < 1.282) = 0.90](https://tex.z-dn.net/?f=P%28z%20%3C%201.282%29%20%3D%200.90)
Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.
That is hip breaths greater than 16.1 in. lies in the larger 10%.
Answer:
684
Step-by-step explanation:
The area of the first big rectangular prism at the bottom is 600 (15*6*4), and the area of the smaller one at the top is 84 (7*3*4). The total area is 684.
First take note of her total amount of money, the amount of magazine cost, and the total weeks they purchased it.
Total: $88
Cost: $3.75
Weeks: 5
Now setup and equation.
88-(3.75 x 5)
88-18.75=69.25
So she will have $69.25 after the 5 weeks of purchasing magazines
