The average age of instructors at a local college is 55, with a standard deviation of 6 years; the average salary is $37,000 wit

Lerok [7]

To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100
Where: CV = Coefficient of Variance
X = Mean/average
SD = Standard Deviation

To determine which one is more variable, just get the coefficient of both and compare.
AGE SALARY

CV = (6/55) x 100 CV = (4,100/37,000) x 100
= 10.90 = 11.08

Based on the results, salary is more variable because 10.90<11.08.

A mathematics book has 360 pages, of which 50% are on algebra, 20% on geometry and the remainder on arithmetic how many pages ar

Arte-miy333 [17]

Answer:

30% of the pages are arithmetic, or 108 pages

Step-by-step explanation:

50% are on algebra = 180 pages

360 x .5 = 180

20% are on geometry = 72 pages

360 x .2 = 72

30% are on arithmetic = 108

180 + 72 + 108 = 360 pages

50% + 20% + 30% = 100%

The cell labelled a is a joint frequency of 48 and the cell labelled b is a marginal frequency of 93.

<h3>What is a frequency table?</h3>

The frequency of an occurrence or a value is the number of times it happens. A frequency table is a list of objects with the frequency of each item shown in the table.

The data is mentioned in the table given below:

We need to find the value of a and b.

Here, Cell Phone+No Cell Phone=Total

To find a:

Add the no lap entries, that is 159+a=207

⇒a=48

To find b:

Add the lap entries, that is 82+11=b.

⇒b=93.

Therefore, the cell labelled a is a joint frequency of 48 and the cell labelled b is a marginal frequency of 93.
