A motorcycle costs 12000. The value of the motorcycle deceases 6% each year. What is the rate each month
quester [9]
There are 12 months in a year and each year it decreases 6% so therefore each month it decreases .5%.

If you were asking the the amount it depreciates each month then you take .5% or .005 of 12000 which is 60 dollars a month.

foot locker uses sales per square foot as a measure of store productivity last year the mean annual sales per square foot was 39
lord [1]

Answer:

There is a 82% probability that th esample mean annual sales per square foot is at least $384.

Step-by-step explanation:

We have a population with mean 390 and standard deviation 45.83.

Samples of size n=49 are taken.

The parameters of the sampling distribution are:

\mu_s=\mu=390\\\\ \sigma_s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{45.83}{\sqrt{49}}=\dfrac{45.83}{7}=6.547

First, we have to calculate the z-score that satisfies:

P(z>z^*)=0.82

This z-score, looked up in a standard normal distribution table, is z=-0.915.

Then, we can calculate the sample mean as:

M=\mu_s+z\cdot\sigma_s=390+(-0.915)\cdot 6.547=390-6=384

There is a 82% probability that th esample mean annual sales per square foot is at least $384.
