Answer:
The mean and standard deviation of Y is $6.56 and $2.77 respectively.
Step-by-step explanation:
Consider the provided information.
Let Y represent their profit on a randomly selected pizza with this promotion.
The company is going to run a promotion where customers get $2 off any size pizza.
Therefore, 
So the mean will be reduced by 2.
If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.
Therefore 
Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.
Part A
blueberries
2/8 × 6/1(drinks) = 12/8cups
banana slice
5/8 × 6/1(drinks) = 30/8cups
30/8 + 12/8 = 42/8 cups<---- that's the answer
Part B
yogurt
4/8 × 6/1 (drinks) = 24/8 cups of yogurt <---
and 6 drinks × 1 cups of ice = 6 cups of ice <---
Answer:
6
Step-by-step explanation:
The ordered pairs that satisfy the inequality are shown in the attachment. There are 6 of them.
You can solve for volume using radius or diameter.
Sphere Volume = <span> 4/3 • <span>π <span>• r³ <span> = <span>( <span>π <span>•d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
</span></span></span></span></span></span></span>
<span>Volume = 3.14159 * 3.0^3 / 6
</span>
<span>Volume = 3.14159 * 9 / 2
</span><span><span><span><span>Volume = </span>14.137 cubic centimeters
</span></span></span>
