Answer: 16

Step-by-step explanation:

Given : Mean : $\mu=100$

Standard deviation : $\sigma =15$

The value of z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= 115

$z=\dfrac{115-100}{15}=1$

The p-value : $P(z>1)=1-P(z$

Now, the number of people smarter than Many is given by :_

$100\times0.1586553=15.86553\approx16$

Hence, there are 16 members smarter than Mandy.

SOLVE FOR X<br><br> plz this is like the 5th time i ask, plz don’t respond with links

sattari [20]

Answer: I used the Pythagorean theorem and got 6.24, but if I was supposed to use another method, just let me know.

The formula is a^2+b^2=c^2

a=5

c=8

b=?

5^2+b^2=8^2

25+b^2=64

b^2=39

b=6.24,

(If it doesn't work, put x=6.24, x=-6.24. It can be both technically, but most teachers ask only for the first one. )
