A IQR means the interquartile range, it would divide the data into 4 different parts called quartiles. Quart means 4!

The quartiles are called quartile 1, quartile 2, quartile 3, and quartile 4 or easier Q1, Q2, Q3, and Q4

It is used to tell when other values are far from the central value called outliers, because they lie outside the range we want them to be. Like if the centers are 3 and there is a number 9, the outliers would be 9 because it is far from 3.

Help Me, Will give 100 points.
Damm [24]

Answer:

The total monthly cost would be $214

Step-by-step explanation:

This is rather simple. They gave us 1,250, which is half of 2,500. Simple multiplication:

1,250  =   2,500

107    =      x

2 ×  1,250 = 2,500

2 × 107 = 214

Therefore, the total monthly cost if the cell phone is used for 2,500 minutes is $214.

The surface area of a solid is 10 square feet. The dimensions of a similar solid are
maxonik [38]

Answer:

90 ft²

Step-by-step explanation:

Given the sides of similar figures in the ratio a : b, then

ratio of areas = a² : b²

Here ratio of sides = 1 : 3 , thus

ratio of areas = 1² : 3² = 1 : 9

That is the surface area of the new solid is 9 times the first

SA = 9 × 10 = 90 ft²

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam
frosja888 [35]

Answer:

Advance tickets cost $30; same-day tickets cost $35.

Step-by-step explanation:

Let a = the cost of an advance ticket

and s = the cost of a same-day ticket

We have two conditions:

                                                         (1)                  a + s = 65

                                                         (2)        15a + 20s = 1150

Subtract a from each side of  (1)     (3)                       s = 65 - a

Substitute (3) into (2)                         15a + 20(65 - a) = 1150  

Distribute the 20                             15a + 1300 - 20a  = 1150

Combine like terms                                     1300 - 5a = 1150

Subtract 1300 from each side                               -5a = -150

Divide each side by -5                    (4)                     a = 30

Substitute (4) into (1)                                          30 + s = 65

Subtract 30 from each side                                     s = 35

Advance tickets cost $30; same-day tickets cost $35.

Check:

(1) 30 + 35 = 65     (2) 15 × 30 + 20 × 35 = 1150

            65 = 65             450    +    700    = 1150

                                                         1150 = 1150
