Answer:
the difference in elevation is 18.5 m
the elevation of submarine is -7.75m
so elevation of helicopter is = - 7.75 + 18.5
=10.75m
thus elevation of helicopter is 10.75 m

Answer:
For 2017 Season:
Mean = 75
Standard deviation = 2.07
For 2018 Season:
Mean = 75
Standard deviation = 5.26
Step-by-step explanation:
The following formulas will be used in these calculations:
Mean = (sum of the values) / n
Variance = ((Σ(x - mean)^2) / (n - 1)
Standard deviation = Variance^0.5
Where;
n = number of values = 8
x = each value
For 2017 Season
Mean = (73 + 77 + 78 + 76 + 74 + 72 + 74 + 76) / 8 = 600 / 8 = 75
Variance = ((73-75)^2 + (77-75)^2 + (78-75)^2 + (76-75)^2 + (74-75)^2 + (72-75)^2 + (74-75)^2 + (76-75)^2) / (8-1) = 30 / 7 = 4.29
Standard deviation = Variance^0.50 = 4.29^0.5 = 2.07
For 2018 Season
Mean = (70 + 69 + 74 + 76 + 84 + 79 + 70 + 78) / 8 = 75
Variance = ((70-75)^2 + (69-75)^2 + (74-75)^2 + (76-75)^2 + (84-75)^2 + (79-75)^2 + (70-75)^2 + (78-75)^2) / (8-1) = 194 / 7 = 27.71
Standard deviation = Variance^0.50 = 27.71^0.5 = 5.26

Answer:
√3/11, π/24, 3/25, 9/100
Step-by-step explanation:
The 2-decimal value of each of the numbers is ...
9/100 = 0.09
π/24 = 0.13
3/25 = 0.12
√3/11 = 0.16
Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...
√3/11, π/24, 3/25, 9/100 . . . . . matches choice B
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled. The value of x will be 85.
<h3>What is a relative frequency table?</h3>
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled.
When we examine the relative frequency, we examine the number of times a certain event happens in comparison to the overall number of events.
We have the following equation for the adult column;


Hence the value of x will be 85.
