If the mean of p, q, r, s and t is 10, calculate the mean of p+1,q+2, r+3,s+4 and t+5

poizon [28]

Answer:

Step-by-step explanation:

The mean of a set of quantities is their sum divided by the number of them.

((p+1) +(q+2) +(r+3) +(s+4) +(t+5))/5

= (p +q +r +s +t)/5 +(1 +2 +3 +4 +5)/5

= mean(p, q, r, s, t) +15/5

= 10 +3 = 13

The mean of p+1,q+2, r+3,s+4 and t+5 is 13.

What percent of 110 is 71.5?

polet [3.4K]

Answer:

65%

Step-by-step explanation:

A percentage OF something is the operation of multiplication, so you would use division [inverse of multiplication] to figure this out:

$\frac{13}{20} = \frac{71\frac{1}{2}}{110}$

* $\frac{13}{20} = 0,65 =$ 65%

* $71\frac{1}{2} = 71,5$

** To convert a decimal to a percentage, you move the decimal mark TWICE TO THE RIGHT. So with that being said, you have your answer.
