Answer:
The number of hits is
Step-by-step explanation:
From the question we are told that
The ratio of the number of hits to the number of chances is equivalent to the batting average
The number of chances is j = 65 + 10 = 75
The number of hit so far is n = 25
Generally the batting average can be represented mathematically as
Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more
So
=>
Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is
=>
=>
Answer:
(E) The z-scores of the height measurements
Step-by-step explanation:
Mean is given by
Where,
n = Number of people
= The heights of people
When converting m to cm the mean would be
So, the mean would change
The median gives us the middle data value when the data values are in ascending order.
So, the median would change
Standard deviation
When converting to centimeters
Hence, the standard deviation would change
When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.
The z score is given by
where,
x = Data point
= Mean
= Standard deviation
When converting to centimeters
Hence, the z score would remain the same
