Answer:
The side lengths are 9, 9 and 7.
Step-by-step explanation:
The sum of the 2 equal sides plus the shorter side is 25 ft.
Representing these unknowns:
2 sides are of length s, and the third (shortest) side is then s - 2.
Thus, s + s + (s - 2) = 25, or 3s = 27. Thus, s = 9 and s-2 = 7
The side lengths are 9, 9 and 7.
The correct answer is B. I am glad I could help.
Answer:
2, 3/4 and 1
Step-by-step explanation:
Answer: 1/8
Step-by-step explanation:
Hypotenuse = √97
One leg = 4
By Pythagoras theorem, second leg² = (√97)² - 4²
= 97 - 16 = 81
So second leg = 9
Area of triangle = 4 x 9 / 2 = 18 sq inch
One sq foot = 144 sq inch
So required fraction = 18/144 = 1/8
<span>"What do you think is the most important problem facing this country today?"
16% of the respondents answered
"crime and violence."
The margin of sampling error was plus or minus 3%
Following the convention that the margin of error is based on a 95% confidence interval, find a 95% confidence interval for the percentage of the population that would respond "crime and violence" to the question asked by the pollsters.
hmmm, im thinking this looks familiar to me, but ill have to see whats wrong about it first
using .16 as p^ and therefore 1-p^ = q^ = .84</span>
