Answer:
2.875
Step-by-step explanation:
you have to change them into decimals. so 5 3/4 would be 5.75 and 2 7/8 would be 2.875. once you do that you can subtract
Answer:
the second one
Step-by-step explanation:
Answer:
the function is EVEN because f(x)= f(-x)
Step-by-step explanation:
Key to find if a function f(x) is even or odd is to replace the x with -x
if the results comes out to be f(x) then it is even function
if the results comes out to be -f(x) then it is odd function
where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.
In given case f(x)=7
if we replace x with -x in above equation then results is 7
f(-x)= 7
hence f(x)= f(-x) = 7

Considering the given data-set, we have that:
- The lowest batting average is of 0.254.
- On the histogram, 5 values would fall into the class 0.251 - 0.280.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed, or the number of elements x in a range of values, as is used for this problem.
For the given 20 batting averages given in the table, we have that:
- Looking at all of them, the lowest value of the table is of 0.254, hence the lowest batting average is of 0.254.
- The measures in the table between 0.251 and 0.28 are: 0.277, 0.265, 0.267, 0.259, 0.254. Hence, this means that on the histogram, 5 values would fall into the class 0.251 - 0.280.
