Gina is a tour boat operator and she wants to know the mean age of all the people in her tour group.

she randomly selects 8 people in the group and asks them for their ages. their responses are 19, 27, 25, 21, 44, 22, 45, and 34.

what is the best estimate of the mean age of all the people in the tour group?

round to the nearest whole number.

enter your answer in the box.

years

30

Step-by-step explanation:

The population mean can be estimated with the sample average, so add up all the ages and divide by how many there are.

(19 + 27 + 25 + 21 + 44 + 22 + 45 + 34) / 8

29.625

Rounded to the nearest whole number, the average age is 30.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
