To find the percentile of a value X in a data set, we divide the number of values lesser than X in the data set by the total number of values in the data set, and then multiply by 100.

In this set

There are 17 values lesser than 1.4

There are 50 values in all.

$P = 100*\frac{17}{50} = 34$

The data speed 1.4Mbps is in the 34th percentile.

The base of a triangle exceeds the height by 4 inches. if the area is 178.5 square inches, find the length of the base and the h

Elanso [62]

A = 1/2 * b * h
A = 178.5
b = h + 4

178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0

h - 17 = 0
h = 17

h + 21 = 0
h = -21 .....not this one because it is negative

b = h + 4
b = 17 + 4
b = 21

so the height is 17 inches and the base is 21 inches <==
