Answer:
The range of ages is found:
D.46
Step-by-step explanation:
Age of college professors is given by a stem and leaf plot such that:
3| 0 2
4| 1 4 4 5
5| 3 5 8 9
6| 2 2 2 5 6 8
7| 5 5 6
Where the numbers on the left side shows the number at 10s place of a certain age, while number on the right side shows that number at Units place. e.g
3| 0 2
It shows ages of:
30 and 32
<h3>Find Range</h3>
Range = Largest number in stem and left plot - Smallest number in stem and leaf plot
Range = 76 - 30
Range = 46

Answer: 25%
Step-by-step explanation:
We know that 20 divided by 5 is 4, so 5 is one-fourth of 20 or 25%.

Answer:
Length = 17 cm
Width = 8 cm
Step-by-step explanation:
Let the length be x cm
Therefore, Width = (x - 9) cm
Perimeter of rectangle = 2(l +w)
50 = 2[x + (x - 9)]
50/2 = 2x - 9
25 = 2x - 9
25+ 9 = 2x
2x = 34
x = 34/2
x = 17 cm
x - 9 = 17 - 9 = 8 cm
Therefore,
Length = 17 cm
Width = 8 cm
Thus, the dimensions of the rectangle are 17 cm and 8 cm.
