(c) a farm brings 15 tons of watermelon to market. find a 90% confidence interval for the population mean cash value of this crop. what is the margin of error? hint: 1 ton is 2000 pounds. (round your answers to two decimal places.)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

1/4 is the asnwer cuz 5/20 is the faction
