nter an equation and an answer to the following question: What is the original list price if the discount is $25 and the discoun

castortr0y [4]

Let us set up an equation, to determine the list price. X represents the original price

.12 * x = 25

In order to solve for X, you must divide .12 from both sides

x = 25/.12

After you divide, you should get the number 208.33

25/.12 = 208.33

So, the original list price is $208.33

At the movie theater, childs admission is $6.10. Adult admission is $9.40. On Tuesday four times as many adult tickets as child

Harlamova29_29 [7]

Answer:

The number of children's tickets sold was 27

Step-by-step explanation:

Let

x ----> the number of children's tickets sold

y ----> the number of adult's tickets sold

we know that

$6.10x+9.40y=1,179.90$ ----> equation A

$y=4x$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A

$6.10x+9.40(4x)=1,179.90$

solve for x

$6.10x+37.6x=1,179.90$

$43.7x=1,179.90$

$x=27$

therefore

The number of children's tickets sold was 27

Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b

Alexxx [7]

Answer:

57.98 yards

Step-by-step explanation:

When the ball is on the ground, the height is $y=0$ , therefore:

$y=-0.017x^2+0.98x+0.33$

$0=-0.017x^2+0.98x+0.33$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-0.98\pm\sqrt{0.98^2-4(-0.017)(0.33)}}{2(-0.017)}$

$x_1=57.98184919$

$x_2=-0.3347903693$

Since distance cannot be negative, the ball landed 57.98 yards down the field from where the goalie kicked the ball.

A procedure for using sample data to find the estimated regression equation is _____. Group of answer choices point estimation i

mr_godi [17]

<em>c. the least squares method. </em>

Regression equation:

In simple linear regression, the predicted value of the dependent variable is given by the equation = b0 + b1x. The values of b0 and b1 are calculated from the data so that the line = b0 + b1X minimizes the total sum of squared errors (error is the difference between the predicted value and the actual value of y).

Least squares method:

The least squares method is a statistical procedure to find the best fit for a set of data points by minimizing the sum of the offsets or residuals of points from the plotted curve.
