Answer: YES
Step-by-step explanation:
<u>Concept</u>
In a right triangle, the square of both legs is equal to the length of hypotenuse squared. This is the Pythagorean theorem: a²+b²=c². For more graphical explanation, please refer to the attachment below.
<u>Given</u>
Leg a = 36 in
Leg b = 48 in
Hypotenuse c = 60 in
<u>Solve</u>
a² + b² = c²
(36)² + (48)² = 3600
(60)² = 3600
3600 = 3600
Therefore, the answer is <u>YES</u>

Answer:
First question the answer is the third one, 4*4*4*4*4
Second: Part A
I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
Answer:
Step-by-step explanation:
A) From the stem-leaf plot, we see that out of 21 tunas, 5 have dangerous levels of copper since the levels go beyond 5.7 parts per million. The required proportion is 5/21=0.2381
B) Given the sample mean is {x}=4.77, sample standard deviation s=1.16 and the sample size is n=21.
Since the population standard deviation is not known, we use t-distribution.
So the 98% CI for mean is
4.77 ± t{1-0.02 /2,20} x 1.16/sqrt(21) = (4.13, 5.41)}
We are sure with 98% confidence the true copper level (in parts per million) lies in the interval (4.13, 5.41)
If you're trying to factor it, the answer would be >> 2<span>(<span>x+y</span><span>)
