26 adult tickets = $12 (cost of an adult movie ticket) • 26 = $312

There were $312 dollars worth of money sold from the adult tickets that were sold for the 10PM show.

$600 - $312 = $288

This means that there were $288 dollars worth of money sold from children’s tickets for the 10PM show.

Since each children ticket is $8, you would do

8x = $288

(X IS HOW MANY CHILDREN TICKETS THAT WERE SOLD)

Once you do that, you would simplify it by dividing 8x by 8 which would give you x by itself and do the same thing for the other side as you have to do the same for both sides of the equal sign. So, you would do $288 divided by 8 and get 36.

x = 36

To check our work, we will substitute the value of x into the equation

8(36) = $288
288 = $288

Therefore, there were 36 children tickets sold for the 10PM show.

Complete Question

The complete question is shown on the first uploaded image

Answer:

Using 2SD Method

The confidence interval is

The interval notation : $(0.108 , 0.212 )$

The interval notation and the sample proportion ± the margin of error

notation: $0.16 \pm 0.052$

The interpretation

There is 95% confidence that the true proportion of those that dislike cilantro lie within the upper(0.212) and the lower(0.108) limit of the calculate confidence interval

Using theory-based method

The 95% confidence interval is

The interval notation : $(0.109 , 0.211 )$

The interval notation and the sample proportion ± the margin of error

notation: $0.16 \pm 0.051$

The interpretation

There is 95% confidence that the true proportion of those that dislike cilantro lie within the upper(0.211) and the lower(0.109) limit of the calculate confidence interval

Using theory-based method

The 88% confidence interval is

The interval notation : $(0.120 , 0.200 )$

The interval notation and the sample proportion ± the margin of

error notation: $0.16 \pm 0.040$

The interpretation is

There is 88% confidence that the true proportion of those that dislike cilantro lie within the upper(0.200 ) and the lower(0.120) limit of the calculate confidence interval.

Step-by-step explanation:

From the question we are told that

The number sample size is n = 200

The number of people that dislike cilantro is k = 32

Generally the sample proportion is mathematically represented as

$\r p = \frac{k}{N}$

=> $\r p = \frac{32}{200}$

=> $\r p = 0.16$

Generally 2SD confidence interval is mathematically represented as

$\r p \pm 2\sqrt{\frac{\r p(1 - \r p)}{n} }$

substituting value

$0.16 \pm 2\sqrt{\frac{0.16(1 - 0.16)}{200} }$

=> $0.16 \pm 0.052$

This can also be represented as

$(0.16 - 0.052 , 0.06 + 0.052)$

=> $(0.108 , 0.212 )$

Generally this confidence interval can be interpreted as

There is 95% confidence that the true proportion of those that dislike cilantro lie within the upper and the lower limit of the calculate confidence interval

Using theory-based method estimate 95% confidence interval

Generally from the question the confidence level is 95% hence the level of significance is calculated as

$\alpha = (100 - 95)\%$

=> $\alpha = 0.05$

The critical value of $\frac{\alpha }{2}$ from the normal distribution table is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the confidence level using theory base method is

$0.16 \pm 1.96 \sqrt{\frac{0.16 (1- 0.16)}{200} }$

=> $0.16 \pm 0.051$

This can also be represented as

$(0.16 - 0.051 , 0.06 + 0.051)$

=> $(0.109 , 0.211 )$

Generally this confidence interval can be interpreted as

There is 95% confidence that the true proportion of those that dislike cilantro lie within the upper(0.211) and the lower(0.109) limit of the calculate confidence interval

Using theory-based method estimate 88% confidence interval

Generally from the question the confidence level is 95% hence the level of significance is calculated as

$\alpha = (100 - 88)\%$

=> $\alpha = 0.12$

The critical value of $\frac{\alpha }{2}$ from the normal distribution table is

$Z_{\frac{\alpha }{2} } =Z_{\frac{0.12 }{2} } = 1.55$

Generally the confidence level using theory base method is

$0.16 \pm 1.55 \sqrt{\frac{0.16 (1- 0.16)}{200} }$

=> $0.16 \pm 0.040$

This can also be represented as

$(0.16 - 0.040 , 0.06 + 0.040)$

=> $(0.120 , 0.200 )$

Generally this confidence interval can be interpreted as

There is 88% confidence that the true proportion of those that dislike cilantro lie within the upper(0.200 ) and the lower(0.120) limit of the calculate confidence interval

How do you find a rate of change

ddd [48]

Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.hope this helped. </span>
