To split the data into quarters, find the
median of the upper and lower half. What are
the medians for the lower (18-28) and upper
(30-37) halves?

Lower:22 and Upper: 32

Step-by-step explanation:

Median is the number in the middle of everything, so you look at the center and you get your answers

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
