The total cost of a cake that serves 20 people is $35.
<u>Step-by-step explanation</u>:
- Total cost = y
- Number of additional servings = x
- The number of additional servings = 20 - 12 = 8. (x=8)
<u>The equation can be formed as</u>:
- Total cost = basic cost + (No. of additional serving
cost per additional serving) - y = 25 + x1.25
- Substitute x=8 in the above equation
- y = 25 + 8(1.25)
- y =25+10
- y = 35
Therefore, the total cost of a cake that serves 20 people is $35.
Given
Mean = 6.625
Standard Deviation = 1.9
Values within 1 standard deviation of mean, mean:
[tex]\begin{gathered} 6.625-1.9<em>We look at the number of values at 5, 6, 7, and 8.</em>
<em />
<em>5 = 2 people</em>
<em>6 = 2 people</em>
<em>7 = 5 people</em>
<em>8 = 3 people</em>
<em />
Total = 2 + 2 + 5 + 3 = 12 people

Missing part of your problem there. If v=5, 3v=15. Assuming you're adding the 9, the answer is 24.
17 is a prime number whereas 26,44 and 65 are the composite numbers.
<u>Step-by-step explanation:</u>
The number 17 does not belong with 26, 44 and 65.
Here 26 is divisible by 2 and 13.
44 is divisible by 2, 4 and 11.
65 is divisible by 5 and 13
But 17 is divisible by 1 and itself, that is it's a prime number, whereas the other numbers 26, 44 and 65 is divided by 1, itself and also by other numbers.
So 17 is a prime number whereas the 65, 26 and 44 are composite numbers.
