The solution set is (9.5, 3.5). Explanation: 9.5(2)+3.5(2) is the same as 19+7 which equals 26. These same numbers are used for x-y=6, which is 9.5-3.5=6.
There are 8 cars which gives between 30 to 50 miles per gallon.
Step-by-step explanation:
- Stem-and-leaf plot are one of the most classical form of plotting.
- The left hand side of vertical line is stem and right is leaf.
- unit digit is leaf and tenths digit is stem.
- 0-9,10-19,20-29,30-39,40-49,50-59,60-69 is range.
- Plotting is done by the number which comes between the range.
- Example between 10-19 there are two points 19 and 19.
- They use discrete variable not continuous.
- The are easy to understand because discrete is counting numbers.
The value c is 19.2
The value d is 160-x
Explanation:
To find the value of c, we need to subtract the original value and the removed value.
Thus,
c = Original - Removed
Let us substitute the value of original and removed from the table.
Thus,

Thus, the value of c is 19.2
To find the value of d, we need to subtract the original value and the removed value.
Thus,
d = Original - Removed
Let us substitute the value of original and removed from the table.
Thus,

Thus, the value of d is 160-x
