A popular television show recently had a 22% market share, which means that 22% were tuned to this show. Assume that an advertiser wants to verify that 22% share value by conducting its own survey with 10 households having TV sets in use at the time of the broadcast. What is the mean number of TV sets tuned into the show

2.2

Step-by-step explanation:

Given that:

the proportion of people that tuned the show = 0.22

sample size n = 10

We can compute the mean number of TV sets tuned into the show by using the formula;

10 × 0.22

 2.2

Thus, the mean number of TV sets that tuned into the show = 2.2

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
