Answer:
And the value for n rounded up would be n = 174
Step-by-step explanation:
We have the following info given:
previous estimation for the deviation
the margin of error desired
represent the confidence
The Margin of error is given by:
If we solve for the value of n we got:
For this problem we know that the confidence is 98% so then the significance level would be 
and the critical value would be:
And replacing we got:
And the value for n rounded up would be n = 174
1. 20 squared + 48 squared = 2704
square root of 2704 is 52. Answer: 52 inches.
2. -18 squared + 82 squared = 6400
square root of 6400 is 80 Answer: 80 inches
Answer: W(x + 4) = x + 8
<u>Step-by-step explanation:</u>
I am assuming the "t" is supposed to be an addition sign "+"
w(x + 4) means to replace all of the x's in the given function with x + 4
W(x) = x + 4
W(x + 4) = (x + 4) + 4
= x + 8
D. go study it I dont know it
I believe the correct answer from the choices listed above is the third option. All of the following proportions are equivalent except <span>a/d=c/b.
</span><span>a/b=c/d
b/a=d/c => a/b = c/d
a/d=c/b not equal to </span>a/b = c/d<span>
a/c=b/d => </span>a/b = c/d
