An adult ticket costs $205 and a child ticket costs $49.

<h2>Explanation:</h2>

Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:

Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child for $459. How much does and adult and child ticket cost?

To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:

Two families are planning a trip to Disney.
The Smith family bought tickets for 2 adults and 3 children for $557.
The Jones family bought tickets for 2 adults and 1 child for $459.

Let:

$x:Cost \ of \ ticket \ per \ adult \\ \\ y: Cost \ of \ ticket \ per \ child$

For the Smith family:

Cost for the 2 adults:

$2x$

Cost for the 3 children:

$3y$

Total cost:

$2x+3y=557$

For the Jones family:

Cost for the 2 adults:

$2x$

Cost for the 1 child:

$y$

Total cost:

$2x+y=459$

So we have the following system of linear equations:

$\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}2x+3y=557\\2x+y=459\end{array}\right.$

Subtracting (2) from (1):

$\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}2x+3y=557\\-(2x+y=459)\end{array}\right. \\ \\ \\ \begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}2x+3y=557\\-2x-y=-459\end{array}\right. \\ \\ \\ (2x-2x)+(3y-y)=557-459 \\ \\ 2y=98 \\ \\ y=49 \\ \\ \\ Finding \ x \ from \ (1): \\ \\ 2x+3(49)=557 \\ \\ 2x=557-147 \\ \\ 2x=410 \\ \\ x=205$

Finally, an adult ticket costs $205 and a child ticket costs $49.

Write an equation for the line that is parallel to the given line and that passes through the given point.

Tom [10]

Answer:

y - 11 = 7(x - 3)

y - 11 = 7x - 21

y = 7x -10

We are continuing to study the difference in average time for completion for the two matching schemes. However, this time we had

IgorLugansk [536]

Answer:

We are 95% confident that the time to completion for the same color method is between 4.617 less to 9.383 less than the different color method.

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence for the difference in the completion time of treatment is and d is,

CI = (-4.617, -9.383)

The parameter of the study is defined as:

treatment_s - treatment_d

Consider the 95% confidence interval, (-4.617, -9.383). The confidence interval consists of all negative values.

This implies that the difference between the completion time of treatment s and d is less than 0, i.e. the completion time of treatment s is less than that for treatment d.

Thus, the complete statement is:

"We are 95% confident that the time to completion for the same color method is between 4.617 less to 9.383 less than the different color method."

Which inequality describes this graph?

ZanzabumX [31]

The inequality that describes this graph of the number line is x ≥ 4

<h3>How to determine the inequality that describes this graph?</h3>

From the question, we have the following properties:

The graph is a number line
The number line extends at both ends
The number line starts from less than -5 and ends at greater than 5
There is a heavy arrow that extends from a circle over positive 4 to the right.

The property 3 above implies that the domain of the number line is the set of all real numbers.

The property 4 above implies that the inequality of the number line is a greater than or equal to inequality, and the value starts from 4

This is represented by the following inequality

x ≥ 4

Hence, the inequality that describes this graph of the number line is x ≥ 4
