Answer:
B. 6(50+2)
Step-by-step explanation:
50 + 2 = 52
Then we are to multiple 6 by 52, resulting in the same original equation as well as the same solution.

A, Adding a constant does nothing to the standard deviation
Step-by-step explanation:
I'm gonna assume s=standard deviation
The standard deviation is just the square root of the second moment minus the first moment squared
Because we were not told otherwise I think it's pretty safe to assume that all events are equally likely
Let's start by calculating the first moment (AKA The mean)
1/5(8+16+14+8+16)= 12.4
Let's then find the second moment
1/5(8²+16²+14²+8²+16²)= 167.2
√(167.2-12.4²)=3.6661
b.
While I could just tell you that adding something to the standard deviation (and the variane as well) doesn't do anything let's calculate it for fun
same process
.2(16+24+22+16+24)= 20.4
.2(16²+24²+22²+16²+24²)=429.6
√(429.6-20.4²)= 3.6661
Answer:
c
Step-by-step explanation:
Negative 7 over 10 minus negative 2 over 10 = negative 5 over 10; therefore, the distance from A to B is absolute value of negative 5 over 10 equals 5 over 10 units.
the correct option is C.
(-7/10) - (-2/10)
then add -7/10 + 2/10 which will equal -5/10
Answer:
-17/12
Step-by-step explanation:
15/4 = 3 3/4
3 3/4 -4 1/3 = 3 9/12 -4 4/12 = -17/12
