Suppose SAT math scores are normally distributed with a mean of 516 and a standard deviation of 115 while ACT math scores have a Normal distribution with a mean of 22
and a standard deviation of 5. Anna scored 650 on the SAT math and Bob scored 29
on the ACT math. Assuming that both tests measure the same kind of ability, who did
better in terms of the standardized z-score?
a. Anna
b. Bob
c. They did relatively the same
d. Impossible to tell because of the scaling.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
