Answer: D
Step-by-step explanation:
Standard Deviation σ2 =
Σ(xi - μ)2/N
=(1 - 5.3)2 + ... + (9 - 5.3)2/10
=68.1/10
= 6.81
σ = √6.81
= 2.60959767014
B) σ2 =
Σ(xi - μ)2/N
=(3 - 61.7)2 + ... + (99 - 61.7)2/10
=58414.1/10
= 5841.41
σ = √5841.41
= 76.429117488036
C) (1 - 11.4)2 + ... + (1 - 11.4)2/10
=8758.4/10
= 875.84
σ = √875.84
= 29.59459410095
D) (79 - 79)2 + ... + (79 - 79)2/10
=0/10
= 0
σ = √0
= 0

Answer:
$2.47
Step-by-step explanation:
Pretend if Mr. Yasin didn't pay for the 3rd box, find out how much he had left after paying for the first 2 boxes.
9.43 - 3.99 - 2.97 = 2.47
Maybe the second from the left, I'm not sure
The population decreases by 4118 so the previous population was 18,318
Answer:
Option (C)
Step-by-step explanation:
Cost of ordering the number of shirts is represented by the function,
f(x) = 12.75x + 3.5
where x = number of players in the bowling team
Since number of players a bowling team can have,
6 ≤ x ≤ 10
Therefore, domain of the function: 6 ≤ x ≤ 10
For x = 6,
f(6) = 12.75(6) + 3.5
= 80
For x = 7,
f(7) = 12.75(7) + 3.5
= 92.75
For x = 8,
f(8) = 12.75(8) + 3.5
= 105.5
For x = 9,
f(9) = 12.75(9) + 3.5
= 118.25
For x = 10,
f(10) = 12.75(10) + 3.5
= 127.5 + 3.5
= 131
Therefore, for the given domain range of the function will be,
Range : {80, 92.75, 105.5, 118.25, 131}
Option (C) will be the answer.
