Ratio of Cake Donuts to Total Donuts = 15/36
Let, the number of people with Cake donuts = x
Then, 15/36 = x/12
x = 12/36 * 15
x = 1/3 * 15
x = 5
In short, Your Answer would be: 5
Hope this helps!
I would definitely use a calculator for this one. Multiply each set of numbers to get an answer for each, then subtract the two I believe. I got 6288547912.
Answer:
The standard deviation = 1.9
Step-by-step explanation:
standard deviation, ρ = sqrt ( 
)
Where u is the mean of the data, 
each given value, and N is the number of data given.
Mean, u = 
= 5.2
So that;
= 
= 0.64
= 
= 0.04
= 
= 10.24
= = 0.04
= 
= 7.84
Sum = 18.8
So that;
= 
= 1.9391
= 1.9
The standard deviation of the given data is 1.9
<span>With
the sum of 99, we will get 50 pairs whole numbers. Why?
Let’s start with
0+ 99
1 + 98
2 + 97
3 + 96
4 + 95
5 + 94
6 + 93
7 + 92
8 + 91
9 + 90
10 + 89
………
……..
43 + 49
44 + 50
Therefore, if you’re going to count all pairs of whole number, you will get 50
pairs of whole number with the sum of 99.</span>
