Answer:

IQR = 5

The IQR covers 50%

Step-by-step explanation:

The interquartile range is the right line of the box minus the left side of the box

UQ - LQ = IQR

8 - 3 = 5

The interquartile range is 5

Now to find the percent in the interquartile range.

The Box divides the data in quartiles or 25%

The dot to the left line is 25%

The left line to the middle is 25%

The middle to the right line is 25%

The right line to the right dote is 25%

From the left line to the right line is 25% + 25% = 50 %

The IQR covers 50%

A jar of natural peanut butter normally cost four dollars today it's on sale for $3.60 what is the percentage of the discount

kakasveta [241]

$4 is the original price of the jar consisting of peanut butter so therefor it = 100%. It's for sale at $3.60, so we divide $4 by 100% so we get the percentage for each cent and then we times it by 3.60 to get the percentage for $3.60 which is 90%. Now we subtract 90% from 100% to get the discounted percentage for 40cents :)
