A soccer club had 22 members with a mean age of 19.
Then 22 new members joined. One is 17 years old, and the other is 30 years old. How did the mean age change after they joined?

Step-by-step explanation:

number of members=22

mean age=19 years

Total age of 22 members=22×19=418 years

age of new members=17 years and 30 years

Total age of 24 members=418+17+30=465 years

mean=465÷24=19.375 years

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
