Answer:
The appropriate answer is "144".
Step-by-step explanation:
Given:
Population standard deviation,
Margin of error,
%
Or,
Now,
Critical value,
= 
= 
= 
The minimum sample size will be:
⇒ 
By putting the values, we get
or,
You would turn 52 into a percent =.52 and then do 182÷52
with would equal 350
Answer:131.78
Step-by-step explanation:
Answer: n=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9n−10n=−3
9n+−10n=−3
(9n+−10n)=−3(Combine Like Terms)
−n=−3
−n=−3
Step 2: Divide both sides by -1.
-n/1 = -3/-1
n = 3
Answer: The x intercept for Line A is 2 and the x-intercept for line B is -6.
Step-by-step explanation:
Line A uses the equation y = -1/2x + 1 and to find the x intercept y has to be zero so set the equation equal 0 and solve for x.
0 = -1/2x + 1 Subtract one from both sides
- 1 -1
-1 = -1/2x divide both sides by -1/2
x = 2
So the x intercept for A is 2
For Line B it already indicates the x intercept because that is when y is 0. So when y is 0 then x is -6.
