Answer:
The lower bound of a 99% C.I for the proportion of defectives = 0.422
Step-by-step explanation:
From the given information:
The point estimate = sample proportion 


= 0.55
At Confidence interval of 99%, the level of significance = 1 - 0.99
= 0.01

Then the margin of error 



E = 0.128156
E ≅ 0.128
At 99% C.I for the population proportion p is: 
= 0.55 - 0.128
= 0.422
Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422

just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
Answer:
the set of side lengths will be d
Answer: The area of the sector will be about 141.3 square inches.
First, we need to find the area of the entire circle. The formula is pi(r^2). Inputting 18 for the radius makes the area of the circle about 1017.36 square inches.
Now, we multiply by the area by the size of the sector. It is 50 degree out of the entire 360 degrees. That is about 13.9%.
Multiply 13.9% by 1017.36 to get an area of about 141.3 square inches for the sector.
Answer: 4/10 is part-to-part. 28/8 is whole to part. 10/6 is part to part. 6/28 is part to whole.
