Answer: 62.13%
Step-by-step explanation:
Given , Salary of Mr. Palahniuk = $1190
Percentage of Salary he spent on groceries = 24%=0.24
Amount he deposited in his saving funds = $165
Amount he spent on groceries = (Percentage of Salary he spent on groceries) x (Salary )
= (0.24) (1190)
= $ 285.6
Now , Money left = (Salary) - [(Amount he deposited in his saving funds)+(Amount he spent on groceries)]
= $1190-[$285.6+$165]
= $1190 - $450.6
=$739.4
Percentage of his salary is left = (Money left )÷ (Salary) x 100
= (739.4) ÷(1190) x 100
≈62.13%
Hence, the percentage of his salary is left = 62.13%
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
