Perpendicular slope: opposite and reciprocal
-4 opposite and reciprocal = 1/4
Y = 1/4x + b
Plug in point
-3 = 1/4(8) + b
-3 = 2 + b, b = -5
Solution: y = 1/4x - 5
Answer: false false true true
Step-by-step explanation:
there is none
The exponential distribution is:
where
The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.
where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:
Sub into conditional probability formula:
Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%
Answer:
y-7=7/5(x+5)
Step-by-step explanation:
Point Slope Form: y-y1=m(x-x1)
m=slope and (x1, y1) is a point on the line
m=7/5
y-7=7/5(x-(-5))
y-7=7/5(x+5)
