Show how to solve the equation in the picture

\left(3\cdot8\cdot x\right)^7\\\\\left(3\cdot2\cdot4\cdot x\right)^7\\\\\left((3\cdot2)\cdot4\cdot x\right)^7\\\\\left(6\cdot4\cdot x\right)^7\\\\6^7\cdot4^7\cdot x^7\\\\

In the second step, I rewrote 8 as 2*4. Then after that I regrouped terms so that the (3*2) can pair up together. This of course turns into 6. After that point, we have 6, 4 and x multiplied together as the base.

The last step uses the rule that (a*b*c)^d = a^d*b^d*c^d, in other words, we apply the exponent d to each term inside the parenthesis. Each term inside gets its own exponent.

An example: (2*4*6)^3 = 2^3*4^3*6^3

The housing market has recovered slowly from the economic crisis of 2008.​ Recently, in one large​ community, realtors randomly
Gwar [14]

Answer:

Step-by-step explanation:

Given that the housing market has recovered slowly from the economic crisis of 2008.​ Recently, in one large​ community, realtors randomly sampled 38 bids from potential buyers to estimate the average loss in home value.

s = sample std deviation = 3000

Sample mean = 9379

Sample size n = 38

df = 37

Std error of sample mean = \frac{s}{\sqrt{n} } \\=486.66

confidence interval 95% = Mean ± t critical * std error

=Mean ±1.687*486.66 = Mean ±821.003

=(8557.997, 10200.003)

a) If std deviation changes to 9000 instead of 3000, margin of error becomes 3 times

Hence 2463.008

b) The more the std deviation the more the width of confidence interval.

Answer:

I think 1/2

Step-by-step explanation:

Since there are 4 coins overall and 2 nickels, then the probabilty is 2/4

2/4 simplified is 1/2

(I've never been too good at probability so sorry if it is wrong)

Why do you need the answer so bad? Are you trying to get a pet?

Need help with this <br>​
defon

Let n be the larger integer and n-2 be the smaller integer.

n² - (n - 2)²

= n² - (n - 2)(n - 2)

= n² - (n² - 4n - 4)

= n² - n² + 4n + 4

= 4n + 4

= 4(n + 1)

No matter what value n is, it will always be a multiple of 4.
