Answer:
Step 1: Calculate the mean (the average weight).
Step 2: Subtract the mean and square the result.
Step 3: Work out the average of those differences.
Step-by-step explanation:
The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
Answer:
30, 5 , 21
Step-by-step explanation:
substitute the values of x into f(x) , then
f(- 5) = (- 5)² + 5 = 25 + 5 = 30
f(0) = 0² + 5 = 0 + 5 = 5
f(4) = 4² + 5 = 16 + 5 = 21
X must be 4.
