Which value can be added to the set below without changing its mean?

{4, 10, 14, 18, 22, 22}

0

15

16

22

value that can be added to the set  without changing its mean is:

15

Step-by-step explanation:

we are given the data set:

{4, 10, 14, 18, 22, 22}

Mean of this set is= (4+10+14+18+22+22)/6

                             = 90/6

                             = 15

     new mean=90/7=12.86

           new mean = 105/7=15

           new mean=106/15=7.066

           new mean=112/15=7.466

  Hence, on adding 15 the mean of the data set do not change    

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
