Answer:

"The interquartile range for the two sets of data are the same"

Step-by-step explanation:

This is a box and whisker plot.

The rectangular box, left-most side is Quartile 1.

Right-most side is Quartile 3.

The middle line is Quartile 2, or mean.

Now, the inter quartile range is the difference in 3rd and 1st quartiles.

So,

IQR = Q3 - Q1

<u>For School #1:</u>

IQR = 86 - 76 = 10

<u>For School #2:</u>

IQR = 90 - 80 = 10

Hence, the IQR is same for both data set.

PLEASE HELP! Oscar and Kim have $22.00 each to spend at a book fair, where all students receive a 30% discount. They both want t
babymother [125]

Answer:

Both of them correct.

$21.945

They have enough money to purchase the book

Step-by-step explanation:

Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.

Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.

The final price is 77% of the original, it will be: $28.50* 77%= $21.945

Both of them can buy the book

Given the following system of equations: −x + y = 2 2x + 4y = 32 What action was completed to create this new equivalent system
tiny-mole [99]

Answer:

you just need to devide by 2 the second equation

Step-by-step explanation:

  • -x + y = 2 (you leave it as it is)

  • 2x + 4y =32 => 2x/2 +4y/2 = 32/2

=> x + 2y =16

we can devide or multiply in an equation by any number we want, as long as we do it to every term.
