An inspector selects three parts (without replacement) from each batch of parts produced by a production line; the batch fails inspection if at least one of these three parts is defective. (a) Compute the probability that a batch fails inspection when it contains 25 parts, of which four are defective. (b) Compute the probability that a batch fails inspection when it contains 50 parts, of which two are defective. (c) If one batch like the one described in Part (a) is inspected each day, what is the average number of days until the first failed inspection

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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
