Answer:
A 65.5%
Step-by-step explanation:
Percent decrease = (original - new)/ original * 100 percent
= (290-100)/290 * 100 %
= 190/290* 100%
=.655172414 * 100%
=65.5172414%
To the nearest tenth percent %
65.5%
Answer:
16
Step-by-step explanation:
(10-6)^2
4^2=16
<em>a</em> = 8 - a train arrives at the station once every 8 minutes, so for any given 8 minute interval, a randomly selected train has uniform probability of arriving at the station at some point in this time.
<em>f(x)</em> = 1/8 - the area under the graph of <em>f(x)</em> must be equal to 1. This area corresponds to a rectangle with length <em>a</em> = 8 and height <em>x</em> such that 8<em>x</em> = 1. Solving for <em>x</em> gives 1/8.
<em>P</em> = 5/8 - this is equal to the area under the graph over the interval [0, 5], which is the area of a rectangle with length 5 and height 1/8.
