Answer:
394/679
Step-by-step explanation:
Probability is the measure of likelihood or chance that an event will occur.
Probability = Possible outcome of event/Total outcome
Total number of people asked if they had run a red light = number of people that responded 'yes' + number of people that responded 'no'
Total outcome = 394+285
Total outcome = 679
Possible outcome = number of people that responded yes = 394
Probability that if a person is chosen at chosen at random, they have run a red light in the last year will be 394/679
Answer:
Step-by-step explanation:
you put the -9 above where it says the -9 and same to the -3
or to solve the equation:
Divide both sides of the equation by the same term
−9=−3−9−3=−3−3
Divide the numbers
−9−3=−3−3
3=−3−3
Cancel terms that are in both the numerator and denominator
Move the variable to the left =3x=3
Solution =3
The perimeter of a square follows the equation P = 4a, in which P is the perimeter and a the length of one side.
We know the perimeter is P = 76, and the length of one side is a = 3x+4.
P = 4a
76 = 4(3x+4)
76 = 12x + 16
We need to solve for x. Let's subtract 16 from both sides to have the variables on a side and the numbers on a side:
76 - 16 = 12x + 16 - 16
60 = 12x
Now, let's divide both sides by 12 to have the variable x on a side and its value on the other
60 = 12x
60/12 = (12x)/12
5 = x
Hope this helps! :D
Answer:
Evaluate the following exponential function when x = 1.Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12
F(1) =
f (x) = 9 (12)Squared X + 12
F(1) =
