Jason : 8,8,11,13,14,14,15,18,21,22,22,27,27,28,30

median = 18

IQR = 27 - 13 = 14

Ed : 7,12,12,15,19,21,21,21,21,22,23,23,26,27,27

median = 21

IQR = 23 - 15 = 8

Their medians cannot be compared based on their IQR's are 6 points apart

Find the distance between the two points (-4, -5) and (1, -2).

Sphinxa [80]

Answer:

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (1, - 2)

d = $\sqrt{(1+4)^2+(-2+5)^2}$

= $\sqrt{5^2+3^2}$

= $\sqrt{25+9}$

= $\sqrt{34}$ → B

On Monday, a localamburger shop said a combined total of 225 hamburgers and cheeseburgers. The number of cheeseburgers sold was

zheka24 [161]

Answer:

h = hamburgers sold

2h - 72 = 578

2h = 650

2 2

h = 325

There were 72 fewer cheeseburgers sold than hamburgers. That means cheeseburgers = 325 - 72

325 - 72 = 253

253 = cheeseburgers

325 = hamburgers

253 + 325 = 578

Hamburgers = 325

Hope this helps :)
