(a) Proportion of Defectives=0.01

Expected Number Defective=

Probability of Rejecting the Shipment=

(b) Proportion of Defectives=0.05

Expected Number Defective=
Probability of Rejecting the Shipment=

(c) Proportion of Defectives=0.1

step-by-step explanation:

8+8+6+6

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

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
