30/8 would be 3 and 3/4, so the two whole numbers would be 3 and 4
Hope this helps!

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:
Length: 19 feet
Width: 10 feet
Area: 190 feet
Step-by-step explanation:
This is a question about ratio.
Length: let be the actual length.
Width: let be the actual width.
Area: A = xy
Answer:
x = 110° (vertically opposite angel)
