Answer:
<h3>
(base)² + (altitude)² = (hypotenuse) ²</h3>
Therefore,
2²+5² = c² will be matched.
Answer:
They are equal
Step-by-step explanation:
Using the rule of exponents
= 
Given
=
= 
The exponents of both expression are 8 and therefore equal
Answer:
9
Step-by-step explanation:
Subtract 1 2 12 12 from both sides of the equation + 1 2 = 2 1 + 1 2 − 1 2 = 2 1 − 1 2 2 Simplify Solution = 9
Answer: 90% confidence interval would be
Step-by-step explanation:
Since we have given that
n₁ = 50
Number of metal tagged penguins survived = 10
So, 
n₂ = 50
Number of electronic tagged penguins = 18
So, 
So, at 90% confidence interval, z = 1.28
So, interval would be
Hence, 90% confidence interval would be
