Answer:
122.0627kg
Step-by-step explanation:
The standard deviation is the square root of the variance.
That means:
From the question, the standard deviation of the weights of the 10 random subjects is 11.0482kg
We substitute to get:
We square both sides to get:
Therefore the variance is 122.0627kg
the value of c(30) is 21.2, which represents the customers final cost of $21.20
d
Answer
y =
-10 + 2y = 7
Add 10 to both sides of the equation
2y = 7 + 10
Add 7 and 10
2y = 17
divide each term in 2y=17 by 2
Divide y by 7
