Answer:
5, -9
Step-by-step explanation:
(x - 5)(x + 9) = 0 These are factors, to get the roots, just set each one equal to zero
x - 5 = 0
x = 5
x + 9 = 0
x = -9
Answer:
We are 95% confident that the percentage of registered voters in the nation planning on voting for Robert Smith is between 49% and 55%.
Step-by-step explanation:
Given that :
Margin of Error = ±3%
Sample Proportion = 52%
Confidence level = 95%
The 95% confidence interval is :
Sample proportion ± margin of error
52% ± 3%
Lower boundary = 52% - 3% = 49%
Upper boundary = 52% + 3% = 55%
The interpretation is that at a given confidence level ; the popukation proportion based on the sample proportion and margin of error is in the confidence interval.
Answer:
Step-by-step explanation:
We essentially need to solve for l; in other words, we must isolate it to one side.
First, notice that the term 
doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by :
A - = 2lw
Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

.5 as a fraction is 1/2 and .005 as a fraction is 5/1000. You need to find a common denominator. To get the 2 in 1/2 to 1000 you multiply by 500. You do the same to the numerator. So 1 x 500 = 500. So it would read 500/1000. Add these 2 fractions together to get 505/1000. Simplify to 101/200.
