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

Artemon [7]

Find cost of pens and mechanical pencils

pen cost=number of pens times cost pe pen
pencost=10 times 0.35=3.50

mech cost=number of mechs times cost pe mech
mechcost=5 times 0.89=4.45

4.45 is more than 3.50
yes, mech cost mre than pens

Given ΔABC, AB = BC = AC . Area of ΔABC = 25 sqrt3 /4 cm. Find the perimeter of ΔABC.

zubka84 [21]

This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.

1/4 + 2/8 adding fractions with unlike denominators show the work

BARSIC [14]

The common denominator of the two fractions is: 8
1/4 = (1*2)/(2*4) = 2/82/8 = (1*2)/(1*8) = 2/8
Fractions adjusted to a common denominator1/4 + 2/8 = 2/8 + 2/82/8 + 2/8 = (2+2)/8(2+2)/8 = 4/84/8 = 1/2
The answer is 1/2.

hope this helps.
