In a sample of 135 ball bearings, the average diameter was found to be 2.99mm with a standard deviation of 0.49. Give a point estimate for the population variance of the diameter of the ball bearings. Round your answer to two decimal places, if necessary.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
