Answer:
ummmmm if im not wrong 34
Step-by-step explanation:
By substitution
f(6) = 1.8×2^(6)
= 1.8×64
= 115.2
Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
Step-by-step explanation:
Since we have given that
Sample size = 400
Mean = $357.75
Standard deviation = $37.89
At 95% confidence level, z = 1.96
We first find the margin of error.
Margin of error is given by
95% confidence interval would be
Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
Answer:
36
Step-by-step explanation:
Let's start by taking two of the smallest prime numbers: 2&3
Then we square both of them:
2²=4
3²=9
Then we multiply 4*9 to get 36.
Perimeter is distance all around the side of the figure, so you would do:
8 + 7 + 19 + 3 + y + x
Plug in y and x that you solved before: 8 + 7 + 19 + 3 + 11 + 4
Add them!: 52
The perimeter is 52 meters.
