You have found the following ages (in years) of 4 tigers. The tigers are randomly selected from the 31 tigers at
your local zoo:
22, 13, 18, 16
Based on your sample, what is the average age of the tigers? What is the estimated variance of the ages?
You may round your answers to the nearest tenth.
Average age:
years old
Variance:

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

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

60: 45 =12: 9 =4: 3 so the answer is 4: 3
