How do I find X in this problem

pogonyaev

You know that BC is congruent to x so you need to solve for x using the ratio:
$\frac{12}{24}=\frac{x}{BC}$

So then we need to find BC.

We know:
$A=\frac{base \times height}{2}$
$28=\frac{BC \times 7}{2}$
Therefore BC =8

Then:
$\frac{12}{24}=\frac{x}{8}$
$x=8 \times \frac{12}{24} = 4$

Answer:

$\sigma = 0.07770$

Step-by-step explanation:

Given

The above table

Required

The standard deviation

First, calculate the class mid-point. This is the average of the class interval.

The mid-point x is:

$x_1 = \frac{1}{2}(15.3 + 15.6) =\frac{1}{2} * 30.9 = 15.45$

$x_2 = \frac{1}{2}(15.6 + 15.9) =\frac{1}{2} * 31.5 = 15.75$

$x_3 = \frac{1}{2}(15.9 + 16.2) =\frac{1}{2} * 32.1 = 16.05$

$x_4 = \frac{1}{2}(16.2 + 16.5) =\frac{1}{2} * 32.7 = 16.35$

$x_5 = \frac{1}{2}(16.5 + 16.8) =\frac{1}{2} * 33.3 = 16.65$

So, we have:

$\begin{array}{cccccc}x & {15.45} & {15.75} & {16.05} & {16.35} & {16.65} \ \\ f & {14} & {25} & {84} & {18} & {9} \ \end{array}$

Calculate mean

$\bar x = \frac{\sum fx}{\sum f}$

$\bar x = \frac{15.45 * 14 + 15.75 * 25 + 16.05 * 84 + 16.35 * 18 + 16.65 * 9}{14 + 25 + 84 + 18 + 9}$

$\bar x = \frac{2402.4}{150}$

$\bar x = 16.016$

The standard deviation is:

$\sigma = \sqrt{\frac{\sum(x_i - \bar x)^2}{\sum f}}$

$\sigma = \sqrt{\frac{(15.45 - 16.016)^2+ (15.75 - 16.016)^2+ (16.05 - 16.016)^2+ (16.35 - 16.016)^2+ (16.65 - 16.016)^2}{14 + 25 + 84 + 18 + 9}}$

$\sigma = \sqrt{\frac{0.90578}{150}}$

$\sigma = \sqrt{0.00603853333}$

$\sigma = 0.07770$

netineya [11]

4³/₄ pints

<h3>Further explanation</h3>

<u>Given:</u>

A-Plus auto body is painting desigs on a customer's car.

They had 18 pints of blue paint on hand.
They used $\frac{1}{2}$ of it for the flames, and $\frac{1}{3}$ of it for the sparks.
They needed $7\frac{3}{4}$ pints of blue paint to paint the next design.

<u>Question:</u>

How many more pints of blue paint will they need?

<u>The Process:</u>

From the denominators 2 and 3 above, we get LCM = 6.

Let us draw a diagram that contains all the pints.

$18 \ pints \div 6 \ units = 3 \rightarrow \boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3} = 18 \ pints$

The flames: $\frac{1}{2}$ or half of 6 unit above, that is $\boxed{3}\boxed{3}\boxed{3} = 9 \ pints$

The sparks: $\frac{1}{3} = \frac{2}{6}$ or 2 of 6 unit above, that is $\boxed{3}\boxed{3} = 6 \ pints$

So, the remainder is 18 - 9 - 6 = 3 pints.

They needed $7\frac{3}{4}$ pints of blue paint to paint the next design.

Let us count how many more pints of blue paint will they need.

$\boxed{7\frac{3}{4} - 3 = ?}$

$\boxed{= \bigg( 7 + \frac{3}{4} \bigg) - 3}$

$\boxed{= 7 - 3 + \frac{3}{4}}$

$\boxed{\boxed{ \ 4\frac{3}{4}}}$

Thus, they $4\frac{3}{4}$ pints more of blue paint.
