Answer:

x as a fraction: 11 $\frac{1}{2}$

Step-by-step explanation:

Variable x cannot be equal to −2 since division by zero is not defined. Multiply both sides of the equation by 9(x+2), the least common multiple of 9,x+2.

2 ( x+ 2) = 9 x 3

Use the distributive property to multiply 2 by x + 2.

2x + 4 = 9 x 3

Multiply 9 and 3 to get 27.

2x + 4 = 27

Subtract 4 from both sides.

2x = 27 - 4

Subtract 4 from 27 to get 23.

2x = 23

Divide both sides by 2.

x = $\frac{23}{2}$

Simplify

11 $\frac{1}{2}$

Answer:

$x=\frac{23}{2}$

Step-by-step explanation:

Hi there!
We are given the following proportion:

$\frac{2}{9} =\frac{3}{x+2}$ , and we want to solve it for x

To solve proportions, we can cross-multiply; in other words, we can multiply the terms in the numerator of one proportion with the terms in the denominator of the second proportion.

This is a property that where if you have the proportion $\frac{a}{b} =\frac{c}{d}$ , it can also be represented as ad=bc
So let's cross multiply; multiply 2 by x+2, and multiply 9 by 3. Then, set them equal to each other.

2(x+2)=9*3

Multiply

2x+4=27
Subtract 4 from both sides

2x=23

Divide both sides by 2

x= $\frac{23}{2}$
The answer can be left as that.
Hope this helps!

Find the distance between the two points in simplest radical form.<br> (-2,1) and (-8,9)

Archy [21]

Answer:

The answer is

<h2>10 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-2,1) and (-8,9)

The distance between them is

$d = \sqrt{ ({ - 2 + 8})^{2} + ({1 - 9})^{2} } \\ = \sqrt{ {6}^{2} + ({ - 8})^{2} } \\ = \sqrt{36 + 64} \: \: \: \: \: \: \: \\ = \sqrt{100} \\ = 10 \: \: \: \: \: \:$

We have the final answer as

<h3>10 units</h3>

The claim is that the white blood cell counts of adult females are normally? distributed, with a standard deviation equal to 1.6

antiseptic1488 [7]

From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean, $\bar{x}=7.43$ and the sample size, n = 38.

The question illustrates a hypothesis chi-square test of variance.

The test statistics for a Chi-squared test of variance is given by
$T=(n-1)\left( \frac{s}{\sigma} \right)^2 \\ \\ =(38-1)\left( \frac{3.07}{1.63} \right)^2 \\ \\ =37(1.883)^2=37(3.5473) \\ \\ =131.25$
