A marketing research company desires to know the mean consumption of milk per week among people over age 3737. They believe that the milk consumption has a mean of 2.32.3 liters, and want to construct a 80%80% confidence interval with a maximum error of 0.060.06 liters. Assuming a standard deviation of 1.41.4 liters, what is the minimum number of people over age 3737 they must include in their sample? Round your answer up to the next integer.

we don't have enough info to solve this

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

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
