Elena wants to estimate what proportion of computers produced at a factory have a certain defect. A random sample of 200 computers shows that 12 computers have
the defect. She is willing to assume independence between computers in the sample.
Based on this sample, which of the following is a 95% confidence interval for the
proportion of computers that have the defect?
12(188)
O 12 + 2.5767
200
O 0.06 + 1.96V
-0.06(0.94)
200
0.06(0.94)
0.06 – 2.576 v

12 + 1.96
12(188)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the answer to this is a. a^2 + b^2 = c^2

actually what is a question i don't understand
