1  \frac{3}{4}  x 6  (or \frac{6}{1}

Change 1 3/4 to an improper fraction = \frac{7}{4}

\frac{7}{4} x\frac{6}{1} = \frac{42}{4}  = 10 \frac{2}{4} cups 
Reduce the answer and get 10 \frac{1}{2} cups

Coach Evans recorded the height, in inches of each player on his team. The results are shown.
marysya [2.9K]

Answer:

3

Step-by-step explanation:

Given:

Team heights (inches):

61, 57, 63, 62, 60, 64, 60, 62, 63

To find: IQRs (interquartile ranges) of the heights for the team

Solution:

A quartile divides the number of terms in the data into four more or less equal parts that is quarters.

For a set of data, a number for which 25% of the data is less than that number is known as the first quartile (Q_1)

For a set of data, a number for which 75% of the data is less than that number is known as the third quartile (Q_3)

Terms in arranged in ascending order:

57,60,60,61,62,62,63,63,64

Number of terms = 9

As number of terms is odd, exclude the middle term that is 62.

Q_1 is median of terms 57,60,60,61

Number of terms (n) = 4

Median = \frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th}  }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{60+60}{2}=\frac{120}{2}=60

So, Q_1=60

So, 25% of the heights of a team is less than 60 inches

Q_3 is the median of terms 62,63,63,64

Median = \frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th}  }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{63+63}{2}=\frac{126}{2}=63

So, Q_3=63

So, 75% of the heights of a team is less than 63 inches

Interquartile range = Q_3-Q_1=63-60=3

The interquartile range is a measure of variability on dividing a data set into quartiles.

The interquartile range is the range of the middle 50% of the terms in the data.

So, 3 is the range of the middle 50% of the heights of the students.

Patrice user a $15 gift certificate when she purchased a pair of sandals. After 8% sales tax was applied to the price of the san
ASHA 777 [7]

Answer:

The sandals cost before tax $25.

Step-by-step explanation:

Let us assume that the sandals cost before tax $x.

So, after giving an 8% tax the price will be x(1 + \frac{8}{100}) = 1.08x.

If the $15 gift certificate on that after tax price and the final cost of the sandals becomes $12, then

1.08x - 15 = 12

⇒ 1.08x = 27

⇒ x = $25

Hence, the sandals cost before tax $25. (Answer)
