For #17 the distance between -6 and 0 is 6 because you are basically counting backwards. It is the same for #18. So the distance would be 18 for #18.

There are four movies showing at the theater, 2/5 of the people bought tickets for the comedy, 1/4 bought tickets for the horror

RUDIKE [14]

Given:

Number of people bought tickets for comedy = $\frac{2}{5}$

Number of people bought tickets for horror = $\frac{1}{4}$

Number of people bought tickets for kids movie = $\frac{3}{10}$

To find the number of people who bought tickets for the action movie.

Let us take,

Total number of tickets = 1

Now,

Total number of tickets for comedy, horror and kids movie are = $(\frac{2}{5} +\frac{1}{4} +\frac{3}{10} )$

So,

$(\frac{2}{5} +\frac{1}{4} +\frac{3}{10} )$

LCM of 5,4,10 = 20

= $\frac{8+5+6}{20}$

= $\frac{19}{20}$

Rest are action movie's tickets.

Therefore,

Number of action movie tickets = $1-\frac{19}{20}$

= $\frac{20-19}{20}$

= $\frac{1}{20}$

Hence,

The number of people who bought the tickets for action movie is $\frac{1}{20}$ .

Whats the value of the equation

Sholpan [36]

13x-2(x+4) = 8x+1 =

13x-2x-8 = 8x+1=

11x-8 = 8x+1

-8 =-3x+1=

-9 = -3x

x = -9/-3 = 3

x = 3

Answer:

Hence, the mean of the potato chips lie between the interval $(1.006, 1.194)$

Given :

data is :

$1.1,1.2,1.0,0.9,1.1,1.3,1.2,1.1,1.0$

Confidence level is $95\%$ .

To find :

Confidence interval.

Explanation :

Mean $\bar{x}$ $=\frac{\sum x}{n}$

$\Rightarrow \bar{x}=\frac{1.1+1.2+1.0+0.9+1.1+1.3+1.2+1.1+1.0}{9}$

$\Rightarrow \bar{x}=\frac{9.9}{9}$

$\Rightarrow \bar{x}=1.1$

Standard deviation $\sigma$ $=\sqrt{\frac{\sum (x-\bar{x})^2}{n-1}}$

$\Rightarrow \sigma=\sqrt{\frac{\sum (x-\bar{x})^2}{n-1}}=0.122$

here, $\alpha=1-\;\text{confidence level}$

$\Rightarrow \alpha=1-0.95=0.05$

$Z_{\frac{\alpha}{2}}=Z_{0.05}=2.306$ by the Z- table

$95\%$ confidence interval is :

$\bar{x}\pm Z_{\frac{\alpha}{2}}\times \frac{\sigma}{\sqrt{n}}$

$\Rightarrow 1.1\pm 2.306\times \frac{0.122}{\sqrt{9}}$

$\Rightarrow 1.1\pm 2.306\times \frac{0.122}{3}$

$\Rightarrow 1.1\pm 0.094$

$\Rightarrow (1.006, 1.194)$

Therefore, the mean of the potato chips lie between the interval $(1.006, 1.194)$
