Answer:

Step-by-step explanation:

18 = 2 * 3 * 3 = 2 *3²

$18*3^{(n+2)} = 2*3^{2}*3^{n+2}\\\\$

$= 2*3^{2+n+2}\\\\= 2*3^{n+4}\\\\= 2(3)^{n+4}$

Hint:

$a^{m}*a^{n} = a^{m+n}$

Answer:

$E(\bar{x}) = 28520$

Standard error of mean = 689

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $28,520

Standard Deviation, σ = $5600

Mean of sampling distribution =

$E(\bar{x}) = \mu = 28520$

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.

Sample size, n = 66

Since the sample size is large, we can use normal distribution for approximation.

Standard error of mean =

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{5600}{\sqrt{66}} = 689.31 \approx 689$

Solve the equation. -4 (y - 2) = 12 y = ?

inna [77]

First you distribute what’s outside the parentheses (the -4)

-4•4= -4y
-4•-2= 8

New equation: -4y+8=12

Now you solve like a normal equation
12-8 is 4

New equation: -4y=4

Now divide
