4x+9=-3x+2
=> 7x=-7 move all x to left side and numbers to right side by changing + to - or - to +
x=-1
About 7.5 miles if you divide 45/3 is 15 so divide 15/2 which is 7.5
We are given that the amount of time for a given color is:
<span>A. </span>Day
Green = 2 min
Red = 3 min
Yellow = 20 sec = 0.333 min
Total day cycle time= 5.33 min
<span>B. </span>Night
Green = 3 min
Red = 4 min
Yellow = 30 sec = 0.5 min
Total night cycle time= 7.5 min
We calculate for the probabilities of waiting at red for
day and night:
Pday= 3 min/5.33 min= 0.5625
Pnight= 4 min/7.5 min= 0.5333
<span>Pdifference= 0.02917 = 2.92%</span>
<span>Therefore it is more likely to wait at red during day
time by 2.92%.</span>
Answer:
See below.
Step-by-step explanation:
5/6 is a fraction. The 5 is in the numerator, and the 6 is in the denominator.
The denominator is the number of parts the unit was divided into. In this case, the denominator is 6. That means one unit, 1, was divided into 6 equal parts. Each part is one-sixth.
The numerator is the number of those parts that you use. 5 in the numerator means to use 5 of those parts, each of which is 1/6 of 1.
In other words, 5/6 means divide 1 into 6 equal parts, and take 5 of those parts.
5/6 is the same as 5 divided by 6, so as a decimal it is 0.8333...
As a percent it is 83.333...%
