A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?

maks197457 [2]

Answer:

Step-by-step explanation:

Recall the formula for the population mean of a data set:

$\mu=\frac{\sum x}{N}$

We already know that μ is 6 and the sum is 48. Substitute:

$6=\frac{48}{N}$

Divide both sides by 48:

$\frac{1}{8}=\frac{1}{N}$

Reciprocal of both sides:

$N=8$

Thus, there are 8 scores in the population size.

And we're done!

What is the sum of this infinite geometric series

nordsb [41]

You probably know that for $|r|$ , we have

$\displaystyle\sum_{i=0}^\infty ar^i=\dfrac a{1-r}$

Your sum starts at $i=1$ , so it's equivalent to

$\displaystyle\sum_{i=1}^\infty 12\left(\dfrac12\right)^i=\sum_{i=0}^\infty 12\left(\dfrac12\right)^i-12\left(\dfrac12\right)^0=\dfrac{12}{1-\frac12}-12=12$

so the answer is A.

slamgirl [31]

Answer:

Option D

Step-by-step explanation:

Given f(x) = $\sqrt[3]{4x}$

g(x) = 2x + 3

Since, $(\frac{f}{g})(x)=\frac{f(x)}{g(x)}$

$=\frac{\sqrt[3]{4x}}{2x+3}$

This function is defined for the denominator is not equal to zero.

(2x + 3) ≠ 0

x ≠ $-\frac{3}{2}$

Therefore, Option D will be the correct option.
