What is the mean cost of replacing brake pads for four different vehicles ai at the following prices $120,$235,$98,$142

1 answer:

4 0

The mean is the average of a set of numbers. So to do that:

add all the numbers 120+235+98+142=$595

Then divide that by the total number in the set, in this case it is 4.

$595/4= $148.75 assuming that the prices given are the final price of the job.

$A_P=5\cdot3=15$

The area of a triangle:

$A_T=\dfrac{1}{2}\cdot5\cdot5=12.5$

The area of the polygon:

[texA=A_P+A_T\\\\A=15+12.5=27.5\ u^2[/tex]
