So we are simply adding them

we will set the denominator equal by multiplying both the numerator and denominator
then just adding the numerator while keeping the denominator. look at my work. so your answer is 5/8

Find a common denominator for both. It is 8. So you leave 1/8 alone and you find out how much you have to multiply the other denominator to get It to 8. 2x4 is 8 so, you multiply 1x4 and that is 4. So the new equation is 4/8+1/8 and that is 5/8

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a me
zimovet [89]

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}

We have to find the value of x such that the probability is 0.975

P( X < x) = P( z < \displaystyle\frac{x - 235}{20})=0.975  

Calculation the value from standard normal z table, we have,  

P( z < 1.960) = 0.975

\displaystyle\frac{x - 235}{20} = 1.960\\x =274.2 \approx 275

Approximately 97.5% of the students spent below $275 on textbook.
