What is 6+2p=24? A. 9 B. 10 C. 25

1 answer:

8 0

The first thing that we want to do is bring like terms to either sides of the equation. That means that we want every number with a "p" on one side of the "=" sign and everything without a "p" on the other side of the "="
6 + 2p = 24
6 - 6 + 2p = 24 - 6 (bring like terms to left side)
2p = 18
(2p) / 2 = 18 / 2 (divide both sides by 2)
p = 9

So the answer is A.

Hope this helped!! :D

Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)

The working equations is

$\frac{(n-1) s^{2} }{ x^{2}_{right} } \ \textless \ S^{2} \ \textless \ \frac{(n-1) s^{2} }{ x^{2}_{left} }$

To find $x^{2}_{right}$ , : (1 - 0.90)/2 = 0.05

To find $x^{2}_{left}$ , : 1 - 0.05 = 0.95

Degrees of freedom = n-1 = 24 - 1 = 23

This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,

$x^{2}_{left} = 13.093$

$x^{2}_{right} = 35.17$

Substitute all values,

$\frac{(24-1) 5.6^{2} }{ 35.17} \ \textless \ S^{2} \ \textless \ \frac{(24-1) 5.6^{2} }{ 13.093} }$

Thus the answer is,

$20.51\ \textless \ S^{2} \ \textless \ 55.09$
