Cise 2.1: J
A population consists of five persons those ages are 10, 20, 30, 40 and
50 years. A random sample of size 2 is to be selected from the
population with replacement.
(i)
List all the possible samples of two persons ages computing the
mean, y of each sample.
(ii)
Obtain the sampling distribution of y.
​

To complete your spring schedule, you must add calculus and physics. at 9: 30, there are three calculus sections and two physics sections; while at 11: 30, there are two calculus sections and three physics sections. how many ways can you complete your schedule if your only open periods are 9: 30 and 11: 30?

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
