Answer:

A. Mean = $41900

B. Median = $37000

C. Mode = $37000

Step-by-step explanation:

A. Mean

Here

n=40

Mean = Sum of values/n

Mean = \frac{(3)(18000)+(3)(22000)+(3)(25000)+(5)(34000)+(17)(37000)+(2)(45000)+52000+(5)(80000)+140000}{40}\\=\frac{54000+66000+75000+170000+629000+90000+52000+400000+140000}{40} \\=\frac{1676000}{40}\\=41900

Mean = $41900

B. Median:

As the number of salaries is even,

the median will be mean of middle two terms

Median= \frac{1}{2}(\frac{n}{2}th\ term+ \frac{n+2}{2}th\ term)\\=  \frac{1}{2}(\frac{40}{2}th\ term+ \frac{40+2}{2}th\ term)\\=\frac{1}{2} (20th + 21st)}\\

The 20th and 21st term will be 37000

So their mean will be same

So,

Median = $37000

C. Mode

Mode is the value which occurs most of the time in data.

the occurrence of 37000 is highest in the given data.

So,

Mode = $37000 ..

If 38 12-m – 82m, what is the value of m?
BigorU [14]

Answer:

m=-\frac{26}{83}

Step-by-step explanation:

Since you are asking for the value of m, it is reasonable to assume that we are dealing with an equation here and you forgot to type the equal sign. Given that, I assume our equality is 38=12-m-82m. Let's solve it step-by-step:

Step 1. Subtract 12 from both sides of the equation

38-12=12-12-m-82m

26=-m-82m

Step 2. Combine like terms (m terms)

26=(-1-82)m

26=-83m

Step 3. Using the reflexive property of equality: if a = b, then b = a

26=-83m

-83m=26

Step 4. Divide both sides of the equation by -83

\frac{-83m}{-83} =\frac{26}{-83}

m=-\frac{26}{83}

We can conclude that the value of m is -\frac{26}{83}.

Next time be more careful writing your question :)
