Answer:
-3
Step-by-step explanation:
We know a=-5
Lets plug this into a+2:
-5+2
=
-3
-3 is the value of a+2, when you plug in -5 as a.
Hope this helps!
Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65
Answer:
C. Uniform distribution
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that X is between values c and d, in which d is greather than y is given by:
In this problem, we have that:
Suppose the probability of a car accident taking place anywhere on a 20-mile stretch of highway is the same, which means that
Somewhere between the 5-mile and 15-mile posts of the highway:
So the correct answer is:
C. Uniform distribution
