Answer:
the time taken is 22 mins
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
Answer:
6.3 x 10°
Step-by-step explanation:
6.3 can be written as 6.3 x 1
recall that anything to the power of zero = 1
hence 10° = 1 substitute this back into the expression above to get:
6.3
= 6.3 x 1
= 6.3 x 10°
Answer:
3 < x < 13
Step-by-step explanation:
<u>Triangle Inequality Theorem</u>
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Let x be the length of the unknown side.
Therefore, x will either be the longest side or one of the shorter sides.
Therefore:
x < 5 + 8
⇒ x < 13
And:
8 < 5 + x
⇒ 3 < x
So the range of possible values of the third side is <u>greater than 3</u> and <u>less than 13</u>: 3 < x < 13
