Assume that adults have IQ scores that are normally distributed with a mean of 101.2 and a standard deviation 20.7. Find the first quartile Qy, which is the IQ score separating the bottom 25% from the top 75%. (Hint: Draw a graph.)
The first quartile is
(Type an integer or decimal rounded to one decimal place as needed.)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d
