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
When the numbers are either too big, or you just want a close product. Such as 1370 and 1547. Round to the nearest number then add to the other.
First, you have to find the moment of inertia along the x and y axes. Constant density is denoted as k.
Then, the radii of gyration for
x = √[I_x/m]
y = [I_y/m]
where m = k(15-4)² = 121k. Then,
x = y = [4880.33k/121k] = 40.33
I hope I was able to help you. Have a good day.

Answer:
D. $56
Step-by-step explanation:
Sandra's taxable income is $39,250.
That amount works for range 2 ($39,250 - $39,300), so her tax is $5,944.
Sandra paid $6,000 in FWT (federal withholding tax), which is greater than $5,944, so we need the refund here.
Subtract 5,944 from 6,000 to get the refund.
6,000 - 5,944
We can go on ahead and just make this 100 - 44 (5,900 - 5,900 = 0).
100 - 44
Her refund is $56.
