Answer:

Step-by-step explanation:

Range = difference between the highest and the lowest

Mode = Data that occurs the most time

Median = Arrange the data in ascending order. The middle data is the median. If number of data is even, median is the average of the two middle terms.

1) Range = 28 -21 = 7

Mode = 25

Number of data (Count the total dots) = 14

Median = average of 7th and 8th term

Median = (25+25)/2 = 50/2 = 25

2) Range = 0.18 - 0.11 = 0.07

Mode = 0.15 and 0.16

Number of data = 23

Median =12th term = 0.15

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

$3x + 4x + 2x = 180$

because the angles of a triangle add up to 180.

When we add them:

$9x = 180$

$x = \frac{180}{9}$

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

$x = 20$
