PLEASE HELP EXPLAIN THIS

Step-by-step explanation:

Look at the number and the angles

Multiple the angles all together that's how u find x

The answer for number one is X=37. This is because 37 is half of 74.

Basically, these are all equal angles. The ones across from eachother are, and the angles that are right next to eachother are always going to equal 180, or half of 360. Number 4 is the same as the rest, but it seems more confusing because of the 5th line. If you add 55 and 85, then divide it by 8, you will get the answer.

Step-by-step explanation:

Interquartile range is the difference between the upper median (Q3) and the lower median (Q1).

First, let's write out each value given in the data. Each dot represents a data point.

We have:

2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7

=>Find the median:

Our median is the middle value. The middle value is the 6th value = 4

==>Upper median Q3) = the middle value of the set of data we have from the median to our far right.

2, 3, 3, 4, 4, |4,| 4, 5, [5], 6, 7

Our upper median = 5

==>Lower median(Q1) = the middle value of the data set we have from our median to our far left.

2, 3, [3], 4, 4, |4,| 4, 5, 5, 6, 7

Lower median = 3

==>Interquartile range = Q3 - Q1 = 5-3 = 2
