Hello!
You draw a table or write this out
If you pick vanilla you can get 4 different fruits
That is 4 different yogurts
If you pick chocolate you can choose 4 different fruits
Same for strawberry
So there are 12 different combinations
The answer is 12
Hope this helps!
The given question is wrong.
Question:
Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).
Answer:
Option C:
3(xa) + 2(x + b)
Solution:
Given expression is 2(x + b) + 3(xa).
To find the equivalent expression using commutative property of addition.
Let us first define the commutative property of addition.
a + b = b + a
You can add in any order.
Now, write the given expression using commutative property.
2(x + b) + 3(xa) = 3(xa) + 2(x + b)
Option C is the correct answer.
Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.
⓵ To calculate the volume of a right circular cylinder, the formula is π times the radius of the circular base² time the height of the cylinder.
⓶ Now that we know that the equation to calculate the volume of a right circular cylinder is :
V = π x (r²) x h
You need to find the numbers to replace the volume (V) and the height (h) in the formula.
We already know that the volume is 320 square feet and that the height is 20 feet.
So we are left with a formula looking like this :
320 = π x (r²) x 20
⓷ Now we need to find the radius of the circular base! To do so, you need to solve this equation and isolate the “r”. Start by simplifying the right side :
320 = π x (r²) x 20
÷20 ÷20
↓
16 = π x r²
÷π ÷π
↓
5,09 ⋍ r²
√ √
↓
2,26 feet ⋍ r
⓸ Now that we knoe the value of the radius of the circular base, all there’s left to do is multiply this number by two in order to find the diameter of the water tank :
2,26 x 2 = d
↓
4,51 feet ⋍ d
So your final answer is : the diameter of the water tank is about 4,51 feet.
** Since I devided by “π”, all the answers I wrote from that point are rounded to the nearest hundredths just to make things easier to visualize, but I kept all of the decimals when doing the calculations. So it is possible that your answer might differ slightly from mine if you use the rounded numbers to calculate everything. Just keep that in mind!
I hope this helped, if there’s anything just let me know! ☻

Step-by-step explanation:
Answer:
d. 0.133
Step-by-step explanation:
-Standard error is calculated using the formula:
#We substitute the given values in the formula to solve for E:
Hence, the standard error is 0.133 and the correct option is d
