$\frac{7x}{15-1} =22$
-----------------
To solve this all it takes is two simple steps
Simplify $\frac{7x}{15-1} =22$
1/2x =22
------------------------
Multiply both sides by 2
2 · $\frac{1}{2}$ = 2 · 22
x = 44

Hey there Smarty!

$\boxed{\boxed{Rearrange \ the \ equation \ by \ subtracting}}$

$\left[\begin{array}{ccc}\boxed{\boxed{ 7*x/15-1-(22)=0 }}\end{array}\right]$

$\boxed{((7* \frac{x}{15)}-1)-22=0}}$

$\left[\begin{array}{ccc} \frac{(7x - 15) }{15} -22=0\end{array}\right]$

$Add \ 345 \ to \ both \ sides \ of \ the \ equation : \\ \\
 7x = 345 \\ \\ Divide \ both \ sides \ of \ the \ equation \ by \ 7:
 x = 345/7 = \boxed{\boxed{49.28}}

13. f(x) = x^4<br> - 9x2 -22x - 24

Anna007 [38]

Answer:

x = 4 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

x^4 - 9 x^2 - 22 x - 24 = 0

The left hand side factors into a product with three terms:

(x - 4) (x + 2) (x^2 + 2 x + 3) = 0

Split into three equations:

x - 4 = 0 or x + 2 = 0 or x^2 + 2 x + 3 = 0

Add 4 to both sides:

x = 4 or x + 2 = 0 or x^2 + 2 x + 3 = 0

Subtract 2 from both sides:

x = 4 or x = -2 or x^2 + 2 x + 3 = 0

Subtract 3 from both sides:

x = 4 or x = -2 or x^2 + 2 x = -3

Add 1 to both sides:

x = 4 or x = -2 or x^2 + 2 x + 1 = -2

Write the left hand side as a square:

x = 4 or x = -2 or (x + 1)^2 = -2

(x + 1)^2 = -2 has no solution since for all x on the real line, (x + 1)^2 >=0 and -2<0:

Answer: x = 4 or x = -2

When testing a claim that the majority of adult Americans are against the death penalty for a person convicted of murder, a rand

Black_prince [1.1K]

Using the z-distribution, it is found that the p-value is of 1.

At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:

$H_0: p \neq 0.5$

At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:

$H_1: p > 0.5$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

In this problem, the parameters are: $\overline{p} = 0.27, p = 0.5, n = 491$ .

Then, the value of the <em>test statistic</em> is:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

$z = \frac{0.27 - 0.5}{\sqrt{\frac{0.5(0.5)}{491}}}$

$z = -10.19$

Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.
