these are typical bowling scores for 16-20 year olds: 74, 88, 89, 95, 99, 100, 101, 106. What is the mean for the data?
2 answers:
Answer:
The answer is 94.
Step-by-step explanation:
In order to determine the answer, we have to know about the mean of a group of values. When we need to calculate the mean, first we have to sum all the values. Then, we have to divide this result by the amount of datas.
In this case, we have 8 datas of differents bowling scores.
The sum of all values is:
Finally, the mean is:
The mean for the data is 94.

In this problem, the function is given as follows:
y = -x²/1000 + x/5
y = -0.001x² + 0.2x.
Hence the coefficients are a = -0.001, b = 0.2, c = 0 and the coordinates of the vertex are given as follows:
