Answer:
Option D) $275
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $235
Standard Deviation, σ = $20
We are given that the distribution of amount of money spent by students 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 0.975
Calculation the value from standard normal z table, we have,
![P( z < 1.960) = 0.975](https://tex.z-dn.net/?f=P%28%20z%20%3C%201.960%29%20%3D%200.975)
Approximately 97.5% of the students spent below $275 on textbook.
How you would solve it is by 8 multiplied by 4.
The formula B*H
So the answer is 32cm squared.
Answer:
1) -10^3 (-10 to the power of 3)
2) r^5 (pie to the power of 5)
3) 1/2^2 + x^3 (1/2 to the power of 2 + x to the power of 3)
