The batting averages of the first three batters in the Eureka College women’s softball team lineup are .310, .301, and .277. If the first three batters are considered as the “lead-off group”, what is the batting average of the group?
A. .301
B. .296
C. There is insufficient information to answer the question
D. None of the above
My answer is D
No.
Add the three numbers together and divide by 3 to find the average of the group.
Consider the distribution of mathematics SAT scores of students in honors calculus at a liberal arts college. What would you expect the shape and variation of the distribution to be?
A. Symmetric with little variation
B. Symmetric with large variation
C. Skewed right with large variation
D. Skewed left with little variation
my answer is d
To find the batting average of the "lead-off group" consisting of the first three batters, you need to calculate the average of their individual batting averages.
The formula to find the average is:
Average = (Sum of all values) / (Number of values)
Let's calculate it step by step:
1. Add up the individual batting averages of the three batters:
.310 + .301 + .277 = .888
2. Divide the sum by the number of batters (which is 3):
.888 / 3 = .296
So, the batting average of the "lead-off group" is .296.
Therefore, the correct answer is B. .296
