Answer:
yes
Step-by-step explanation:
because area of sphere equals =

so if we doubled the radius the surface area will be doubled
I think the answer is 78.53982

Answer:
The mean will stay the same.
The standard deviation will decrease.
Step-by-step explanation:
For the 5 cards, she has received, the mean will be:
μ=(∑x)/n
=125/5
=25
The mean is 25 and the standard deviation is 10.
σ=10
If a new card is received with $25, then the sum will be $150
So the new mean will be:
μ'=(∑x)/n
=150/6
=25
And the new standard deviation will be:
σ'= 9.12
We can clearly see that
μ= μ'
and
σ> σ'
So the mean will remain the same and standard deviation will decrease.

Answer:
[see below]
Step-by-step explanation:
A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.
The slope of 2x + 8y = 12 is
, and it's y-intercept is
.
Since parallel lines have the same slope but not the same y-intercept, I would use
.
Any equation that has -1/4 as the slope would work.
When graphed together, they show as a system with no solution.
Hope this helps.
