There is a traffic light at the intersection of Main Street and Durham Avenue. The traffic light on Main Street follows a cycle. It is green for 30 seconds, yellow for 5 seconds, and red for 25 seconds. As you travel along Main and approach the intersection, what is the probability that the first color you see is green?

Answers

Answer 1
Answer:

There is a 50% chance that the first color I see will be green color.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, The traffic light on Main Street follows a cycle. It is green for 30 seconds, yellow for 5 seconds, and red for 25 seconds.

∴ The sample space N(S) = 60.

So, The probability that the first color I see is green is P(G) = N(G)/N(S).

= 30/60.

= 1/2.

Answer 2
Answer: Probability is defined as the number of desired outcomes over all possible outcomes. Lets say each second is one possible outcome. This means there is 30 different desired outcomes out of 60 possible outcomes. The probability therefore is 30/60, simplified to 1/2.

If 45% of x is 200, what is x?

Answers

' 45% ' means ' 0.45 ' .
' of ' means ' times '.

                                               0.45 times 'x'  = 200

Divide each side by 0.45 :                       x  =  200/0.45 

                                                                   x  =  444 and 4/9 .    
45% of x=200
(45/100)x=200
x=(200*100) / 45=444.4444....≈444.44


Answer: x=444.44

To check
45% of  444.44=0.45 * 444.44≈200

140% of what number is 35

Answers

Hello :)

140% of 35 is 25                 
x = 25
We assume, that the number 35 is 100% cause it's the output value of the task, X is the value that we are looking for if 35 is 100% then, we can write it down like thiss ↓

 35= 100%

 we know, that x is 140% of the output value, so we can write it down as↓

x= 140% which leads use to 2 simple equations now

35= 100%
x= 140%

where left side of both of them have the same units so, we can do something likee that ↓

35/x= 100%/140% now we have to solve the equation

35/x= 100/140
(35/x)·x= (100/140)·x
multiply both sides of the equation by x
35= 0.714285714286·x
divide both sides of the equation by
(0.714285714286) to get x
35/0.714285714286= x
which would be

49= x
x= 49

now we are here - 140% of 35= 49, THERE's YOUR ANSWER IK ITS LENGTHY BUT THATS ALL THE STEPS TO HELP U . HAVE GREAT DAY
