-1/2(2n + 4) + 6 = –9 + 4(2n + 1)

Mathematics
1 answer:
Blababa [14]3 years ago
8 0

Answer: 1/3=n

Step-by-step explanation:

-1/2(2n + 4) + 6 = –9 + 4(2n + 1)

Distribute:

-1n-2+6=-9+8n+4

Combine like terms:

-1n-2+6=-9+8n+4

-1n+4=-5+8n

Add 1n on both sides:

-1n+4=-5+8n

-1n+1n+4=-5+8n+1n

4=-5+9n

Add 5 on both sides:

4+5=-5+5+9n

9=9n

Divide 9 on both sides:

9/9=9n/9

1=n

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.

Answer:

  the function is either increasing or decreasing

Step-by-step explanation:

For m ≠ 0, the function must be either increasing or decreasing. If the function is increasing, it will have its maximum value at the right end of the interval. If it is decreasing, its maximum value will be at the left end of the interval.

How many significant figures will there be in the answer to the following problem?<br> 7500×45.0879
Alchen [17]
Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
