Answer:
3
Step-by-step explanation:
C(n) = 5n, 0 ≤ n ≤ 10 You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.
C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.
C(10) = 5(10) Input the value 10 as x.
C(10) = 50 Simplified
Next,
C(n) = 4n + 5, n > 10 You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.
C(n) = 4n + 5, n > 10 ← You can ignore the n>10 part.
C(12) = 4(12) + 5, n > 10 Input the value of 12 as x.
C(12) = 48 + 5 Simplify
C(12) = 53
Finally,
The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).
C(12) - C(10)
(53) - (50) Input the values of C(12) and C(10).
= 3 Simplify.
The answer is 3.
Answer:
15 seconds
Step-by-step explanation:
Because the split id 25% and 75%, we could create another average pretending that there are four kids, one who ran in 12 seconds, and three who ran in 16.
Equation for averages: (a₁ + a₂ + a₃ + ... )/ n
Plug in:<em> (12 + 16 + 16 + 16)/4</em>
Add: 60/4
Divide: 15 seconds
