An aircraft seam requires 25 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. a. If 15% of all seams need reworking, what is the probability that a rivet is defective

There is a 0.15 probability that the rivets chosen i s DEFECTIVE.

Step-by-step explanation:

The total number of rivets required = 25

Now, out of the total rivets, 15%  need reworking.

So, the percentage of defective rivets = 15%

Calculating 15% of 25, we get:

So, in total 3.75 rivets are DEFECTIVE.

The probability of choosing  a defective rivet  =

So, there is a 0.15 probability that the rivets chosen is DEFECTIVE.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
