19) student heights in inches:

54, 55.5, 56, 56, 56.5, 57, 58, 58, 58, 58.5,
58.5, 59, 59, 59.5, 60, 60, 60.5, 61, 63, 72

mrs. blackwell's class is getting a new student next week. the current students want to predict the height of the new student. they record the height of everyone in the class. which measure of center should they use to make the prediction and what should be their prediction?
a) the mean and they should predict 59 inches
b) the mean and they should predict 58.5 inches
c) the median and they should predict 59 inches
d) the median and they should predict 58.5 inches

D. The Median and they should predict 58.5 inches.

Step-by-step explanation: Before we start, we want to use median. This is because there is an outlier, 72, and that would mess up the mean by a small yet noticeable margin.

Since the median picks both numbers 58.5 and 58.5, that means that the answer will be D. The Median and they should predict 58.5 inches.

D The median and they should predict 58.5

Step-by-step explanation:

If you count from the outsides and go to the inside with a pencil or you're fingers then you get 58.5 :D

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

r and t.

both are 64 degrees.
