26=8+v I dont know how to do this and I need help
Goshia [24]
26 = 8 + v equals v = 18.

First, 
subtract 8 from both sides. Your problem should look like 26 - 8 = v.
Second, simplify 26 - 8 to get 18. Your problem should look like 18 = v.
Third, switch sides. Your problem should look like v = 18, which is the correct answer.

f(x)=2( \sqrt[3]{27})^{2x}

Here 2 on left most side is the coefficient, 2x is the exponent and the of the function is cube root of 27.

So,

Base= \sqrt[3]{27}  \\  \\ 
Base= \sqrt[3]{3^{3} } \\  \\ 
Base=3

Thus, the simplified base for the function is 3. So correct answer is option  B

Describe in detail how you would construct a 95% confidence interval for a set of 30 data points whose mean is 20 and population
postnew [5]

Answer:

We have been given confidence interval 95%, mean 20 , data set 30 and standard deviation 3.

We will use the formula: mean\pm \frac{\sigma}{\sqrt{n}}\cdot (z-score)

Here,mean=20,\sigma=3,n=30,z-score=1.96

Z-score value at 95% confidence interval is 1.96

On substituting the values in the formula to plug the values:

20\pm\frac{3}{\sqrt{30}}\cdot (1.96)

Now, we have a formula for marginal error:z\cdot \frac{\sigma}{\sqrt{n}}

Marginal error means your answer will be within that percentage only.

Say you have 3% marginal means your value will be within 3% real population 95% of the time.
