Write an equation to represent the total amount Shauna will owe her parents

1 answer:

5 0

This would actually be a very broad question. So, when considering these kinds of questions, one thing that we would really want to consider would be the $(x)$ value in this case. We would want to find the amount, and also the terms of the expression.

So, let's suppose that the amount would be 200.

And let's say that Shauna makes 5 a week.

Then the expression would then look like $\boxed{5w=200}$

$(w)=weeks \\ \\ (5)= how \ much \ she \ makes \ in \ a \ week. \\ \\ so \ we \ do \ the \ amount \ she \ makes, \ and \ then \ \\multiplied \ by \ the \ amount \ of 
 \ weeks.$

I hope this would help you in your case of the problem! :)

Which of the following points lie in the solution set to the following system of inequalities? y < −3x + 3 y < x + 2

sweet-ann [11.9K]

Answer:

$y < 6 \\ x < 4 \\$

$x( \frac{3y}{?4} - \frac{1}{2?} \frac{2y}{?3} )y < 6 \\ y( \frac{3x}{?2} 4x + \frac{2}{?3} )x < 4$

Write the equation of the line that passes through (-1, 11) and (3, -5)

Genrish500 [490]

Answer:

y= -4x+7

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Let's find the gradient of the line first.

$gradient = \frac{y1 - y2}{x1 - x2}$

Using the above formula,

$m = \frac{11 - ( - 5)}{ - 1 - 3} \\ m = \frac{11 + 5}{ - 4} \\ m = \frac{16}{ - 4} \\ m = - 4$

Susbt. m= -4 into the equation:

y= -4x +c

Subst. a coordinate to find c.

When x=3, y= -5,

-5= -4(3) +c

-5= -12 +c

c= 12 -5

c=7

Thus the equation of the line is y= -4x +7.

hoose the correct definition of a sampling distribution. The sampling distribution of a statistic of size n n is the distributio

sergey [27]

Answer:

Correct option:

"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."

Step-by-step explanation:

The sampling distribution is a probability distribution of a sample statistic.

A sample statistic is a numerical value representing a characteristic of a sample. For example, the sample mean represents the mean value of the sample, the sample variance represent the variance of the sample. Both of these values are sample statistic.

A statistic is an unbiased estimator of the parameter value.

That is, the sample mean value can be used to estimate the value of population mean.

If various large samples are taken from a population and the sample statistic value is computed for each of these samples, then the probability distribution of theses sample statistic is known as the sampling distribution.

The mean of the sampling distribution is same as the population mean and the standard deviation of the sampling distribution is known as the standard error.

The correct option is:

"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."

A small airplane flies 750 miles with an average speed of 250 miles per hour. 1.75 hours after the plane leaves, a Boeing 747 le

sleet_krkn [62]

Answer:

The average speed of the 747 was of 600 miles per hour.

Step-by-step explanation:

A small airplane flies 750 miles with an average speed of 250 miles per hour.

Velocity is distance divided by time, and here, we find the time of the small airplane. So

$v = \frac{d}{t}$
