Answer:

a) $42,580

b) $43,900

Step-by-step explanation:

Recall, "mode" refers to the value which occurs most frequently.

In this case, the question says that there are 2 modes,

this means $34,000 and $50,500 both share the spot for the most frequently appearing salary.

because there are only 5 employees (and hence 5 salaries), the only possible way that there are two modes is if there are two of each mode, leaving only the last salary unknown.

i.e  if we list the 5 salaries (in no particular order)

$34,000   $34,000  $50,500   $50,500   $ x

where x is the 5th unknown salary.

Given that the mean is $42,100

Then (34,000 + 34,000 + 50,500 + 50,500 + x) / 5 = 42,100

solving for x gives x = $41,500

Now we know all the values, we can rearrange them in increasing value:

$34,000   $34,000  $41,500   $50,500   $50,500  

from this, we can see that the median salary is $41,500

Given that the median salary gets a $2400 raise,

the new median salary = $41,500 + $2400 = $43,900 (Ans for part b)

new mean salary,

= ($34,000  + $34,000 + $43,900 +  $50,500  + $50,500  ) / 5

= $42,580 (answer for part a)

Can I get some help thank u sm
natali 33 [55]

Answer:

<h3>11</h3>

Step-by-step explanation:

The sum of interior angles is equal to exterior angle

Given the following

Interior angles = 5x + 10 and 58

Exterior angle 11x+2

According to the postulate:

5x + 10 + 58 = 11x + 2

5x + 68 = 11x + 2

Collect like terms

5x -11x = 2 - 68

-6x = -66

x = -66/-6

<em>x = 11</em>

<em>The value of x is 11</em>

<em></em>
