The weekly salaries of six employees at McDonalds are $140, $220, $90, $180, $140, $200. For these six salaries, determine: (a)

lys-0071 [83]

Answer:

a) Mean = 161.666667

b)Mode = 140

c) Median =160

d) Range =130

Step-by-step explanation:

Given that the weekly salaries of six employees =$140, $220, $90, $180, $140, $200

Mean =Total number of salaries/ Number of salaries

=$140 +$220 +$90 +$180 + $140 +$200 /6=970/6= 161.666667

Mode = The number with the highest frequency ie the number that occurs most in the listed salaries

$140, $220, $90, $180, $140, $200

Therefore 140 is the mode

Median = The number that occurs in the middle, Now that we have a list of even Numbers, our median would be the sum of the two middle numbers divided by 2 after arranging in ascending order fro least to greatest

$90, $140,$140, $180, $200,$220

Median =$140+ $180 / 2 = 160

Range = The difference between the highest and lowest number in the sample

$220-$90=130

Answer:

The dimensions are:

$3(2x+1)$ by $(7x+5)$

Step-by-step explanation:

The area of the rectangle is given as

$A=42x^2+51x+15$

The factored form of this quadratic trinomial gives the dimensions of the rectangle.

We factor 3 first to obtain;

$A=3(14x^2+17x+5)$

We split the middle term to get;

$A=3(14x^2+10x+7x+5)$

We factor within the parenthesis to get;

$A=3(2x(7x+5)+1(7x+5))$

We factor further to get;

$A=3(2x+1)(7x+5)$

The dimensions are:

$3(2x+1)$ by $(7x+5)$

Then the perimeter will be

$2(6x+3+7x+5)=26x+16\:\:\:\boxed{\sqrt{} }$
