The given points are
R=(8,-2) , S=(11,-6), O=(-3,-9), and P=(0,-13)
To find the value of u and v, we have to perform subtraction of the points . That is
Since we get the same values of u and v , therefore the two vectors are equal .
Dover Motors is a car dealership that sells new and used cars. Suppose they sold 140 used cars during the first quarter of 2011.
The average selling price was $10,325 with a standard deviation of $2,880. A random sample of 60 used cars from this population was selected. What is the probability that the sample mean exceeds $10,000?
1 answer:
Answer:
The probability that the sample mean exceeds $10,000 is 0.8078.
Step-by-step explanation:
The objective of the problem is obtained below:
From the given information, let X denotes the number of used cars which follows normal distribution with mean 10,325 and the standard deviation of 2,880 and sample size is 60 used cars. That is, u=10,325,δ = 2,880 and n=60
are used to estimate the probability that the sample mean exceeds 10,000.
