Imagine we measured the height of all the male students at a particular college. We found that the average height of men at this

school was 70 inches (5'10") with a standard deviation of 2 inches and the distribution is approximately normal in shape. If we were to randomly select one male student from this college, what is the probability that this student is 73 inches (6'1") or taller?

Answer:0.0668

Step-by-step explanation:

As per given we have,

\mu=70  \sigma= 2

Also, the distribution is approximately normal in shape.

since , z=\dfrac{x-\mu}{\sigma}

z-score corresponds to x= 73 will be :_

z=\dfrac{73-70}{2}=1.5

P-value = P(x\geq73)=P(z\geq1.5)

=1-P(z

Hence, the probability that this student is 73 inches (6'1") or taller = 0.0668

One half of a number is 14 more than 2 times the number.
frozen [14]

1/2 * n = 2n + 14

Multiply everything by 2 to get rid of the fraction

n = 4n + 28

n - 4n = 28

-3n = 28

n = -9.333333

n = -28/3

What is -3/2 to the 2nd power
natta225 [31]

Answer:

9/4   OR    2 1/4

Step-by-step explanation:

-3/2 to the second power is -3/2 * -3/2 so you multiply the numerators together and you multiply the denominators together then put it back as a fraction

-3 *-3 = 9

2 *2 =4

9/4     or in mixed form     2 1/4
