2/9 of the people on the restaurant are adults. If there are 95 more children than adults, how many children are there in the re

lana [24]

let's call the children "c" and the adults "a"

the total # of people in the restaurant = c+a
so 2/9 of (c+a) = a

therefore 2/9c + 2/9a = a
and a + 95 = c since there are 95 MORE children.

Let's substitute a+95 for c in the equation 2/9(c+a) = a
this gives us 2/9(a+95 + a) = a
then 2/9 a + 2/9(95) + 2/9(a) = a
so 4/9a +190/9 = a
and 190/9 = 5/9 a
so 190 must = 5a
finally a = 38 so c must = 38 + 95 = 133 there are 133 children

Suppose the z-score of your grade on this Statistics exam turns out to be z=0.87. Which of the following is the best interpretat

exis [7]

Answer:

c.My grade is 0.87 standard deviations above the mean.

Step-by-step explanation:

given that the z-score of your grade on this Statistics exam turns out to be z=0.87.

Z score is nothing but std normal variate

Any normal distribution can be converted into std normal by the transformation

Z = $\frac{x-\mu}{\sigma}$

Thus when z=0.87 we mean

x = Mean +0.87 sigma

Or my grade is 0.87 std deviations above the mean

Hence option C is right.

c.My grade is 0.87 standard deviations above the mean.
