Step-by-step explanation:
so 5/9(86-32) then you take
86-32=(54)
now it look like C=5/9=(54)
C=30
so c=30 is the answer :)
Your answer is <span>132^2

20( -1.5r + 0.75)
Multiply everything by 20
= -30r + 15
Answer:
4
Step-by-step explanation:
Class width is said to be the difference between the upper class limit and the lower class limit consecutive classes of a grouped data. To calculate class width, this formula can be used:
CW = UCL - LCL
Where,
CW= Class width
UCL= Upper class limit
LCL= Lower class limit
From the table above:
For class 1, CW = 64 - 60 = 4
For class 2, CW = 69 - 65 = 4
For class 3, CW = 74 - 70 = 4
For class 4, CW = 79 - 75 = 4
For class 5, CW = 84 - 80 = 4
Therefore, the class width of the grouped data = 4
