Velocity equals distance over time, so take 260 divided by 4 and get an average speed of 65 mph.
(5,-2)
(-3,2)
5 and -3 are y you choose which one to be one and which one to be two. the y and the x have to be over each other. but you choose which one to be y1 and y2
y1-y2
_____
x1-x2
the answer would be -2
Answer:
14/15
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15
14/15 is your answer.

Answer:
The probability that an item selected for inspection is classified as defective is 0.01485.
Step-by-step explanation:
Denote the events as follows:
A₁ = an item produced by the company is defective.
A₂ = an item produced by the company is not defective.
X = an item is classified as defective by the inspector.
Given:
P (X|A₁) = 0.99
P (X|A₂) = 0.005
P (A₁) = 0.01
P (A₂) = 1 - P (A₁) = 1 - 0.01 = 0.99
The law of total probability states that:
Use this law to compute the probability that an item selected for inspection is classified as defective as follows:
Thus, the probability that an item selected for inspection is classified as defective is 0.01485.
