Answer:

y = 5

Step-by-step explanation:

Hello there!

Y is our unknown quantity. We need to find for y.

To do this we will isolate the variable so it equals a number that makes the statement for x true.

To solve this, we will use the division property of equality since this is a multiplication equation. y has to be less than 40.

So we will divide 8/8 to isolate y on one side and then do 40/8 (herby the division property of equality)

Then our answer should be y = 5

To double- check this we could simply substitute 5 for y in the equation; 5 • 8 = 40

Therefore this statement holds to be true

Hope this helps you! :)

Answer:

Second class have higher marks and greater spread.

Step-by-step explanation:

First box plot represents class first. From the first box plot, we get

$\text{Minimum value }= 53,Q_1=62,Median=80,Q_3=86,\text{Maximum value }= 89$

$Range=Maximum-Minimum=89-53=36$

$IQR=Q_3-Q-1=86-62=24$

Second box plot represents class second. From the second box plot, we get

$\text{Minimum value }= 56,Q_1=62,Median=74,Q_3=89,\text{Maximum value }= 96$

$Range=Maximum-Minimum=96-56=40$

$IQR=Q_3-Q-1=89-62=27$

First class has greater minimum value, first quartile of both classes are same, second class has greater median, first class has greater third quartile and first class has greater maximum value. It means second class have higher marks but class first have less variation.

Second class has greater range and greater inter quartile range. It means data of second class has greater spread.

Therefore, second class have higher marks and greater spread.
