"Ten subtracted from the quotient of a number<br> and 5 is 18."

Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

(X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

(X divided by 5)-10=18

By solving the above equation, find ‘X’

(X divided by 5) = 18 + 10

X/5=28

X = 28 x 5 = 140

fgiga [73]

The stem and leaf diagram is shown below

There are a total of 48 data

Question a:
The frequency in the stem for 9 to 9.9 is 13 data

Question b:
The location of the first quartile is given by $\frac{n+1}{4}$ , where 'n' is the number of data

We have n = 48

Location of the first quartile is at $\frac{48+1}{4}= \frac{49}{4}= 12.25$ rounded down to 12

The value of the lower quartile is on the $12^{th}$ on the diagram which is 8.7
