The probability that all 4 cards are face cards is 0.00182842367.

The face cards are the King, Queen, and Jack (sometimes known as the Knaves). There are 12 face cards in the 52-card deck of playing cards.

The cards are drawn without replacement,

The probability of getting a face card in first draw is 12/52.

As it is without replacement, in the second draw the probability is 11/51.

In third draw, it is 10/50.

In the fourth draw the probability is 9/49.

We have to draw all the four cards, so we multiply the probabilities, to get the final probability.

=12/52x 11/51 x 10/50 x 9/49

=0.00182842367.

Therefore, the probability that all 4 cards are face cards is 0.00182842367.

The linear equation is 10C+13A=859 and number of children ticket is 17.

What is linear equation ?

 A linear equation is also known as a one degree equation. The linear equation's highest power is 1. Linear equations are equations with variables on both sides that are multiplied by a constant.

Let us take Number of children's ticket as C and number of adult's ticket as A.

Here cost price of one adult ticket = $13

Cost price of one children ticket =$10

A total of $859 was collected in ticket sales for the 7:15PM show.

Total cost price = cost price of children ticket + cost price of adult ticket

=> Total cost price = 10*C+13*A

=> 859=10C+13A

Hence the linear equation is 10A+13A=859.

Here If number of adult ticket = 53. Then

=> 13*53+10C=859

=>689+10=859

=>10C= 859-689=170

=> C=170/10 = 17.

Hence the number of children ticket is 17.

The angle θ = 170° and  θ = 350°  have the same Sine and Cosine as 10° respectively

Since the Sine and Cosine of angle 10° are positive

In order to find an angle θ with 0° < θ < 360° that has the same Sine and

Cosine as 10°, we have to check the quadrants in Trigonometry where Sine and Cosine are positive

1st quadrant (0° - 90°) => Sine is positive (10° is here)

2nd quadrant (91° - 180°) => Sine is positive

3rd quadrant (181° - 270°) => None is postive

4th quadrant (271° - 360°) => Cosine is positive

We will consider the 2nd and 4th quadrants:

2nd quadrant: Sine 10° = Sine (180 - 10)° = Sine 170°

4th quadrant: Cosine 10° = Cosine (360 - 10)° = Cosine 350°

Therefore, θ = 170 degrees and  θ = 350 degrees have the same Sine and Cosine as 10° respectively

Answer:

we use to work out dividing a fraction by a whole number.

A scatter plot of the data is shown in the image attached below.

An equation for the least squares regression line (trend line) is y = -3.49x + 93.14

In order to determine a linear equation for the least squares regression line (trend line) that models the data points contained in the table (see attachment), we would have to use a scatter plot.

In this scenario, the number of absences would be plotted on the x-axis of the scatter plot while the algebra grade would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the number of absences and algebra grade in the table, a linear equation for the least squares regression line (trend line) in terms of the problem is given by:

Cost price =$4

Operating expenses = 110% or 1.1

Profit = 130% or 1.3

Let plug in the formula

Step-by-step explanation:

The period used = 4 years, Rate used = 6%, the PV factor used = 0.792, and the PV of the amount desired at end of the period = $7049.63.

According to the given question, the required solution would be as:

The period used = 4 years,

Rate Used = 6%

We know that,

PV factor = 1/(1+r)ⁿ

Here r = 6% = 6/100 = 0.06, and n = 4

PV factor = 1/(1+0.06)⁴

PV factor = 1/(1.06)⁴

PV factor = 0.792

PV of the amount desired at end of the period = FV/(1+r)ⁿ

Here FV = $8,900.00

PV of the amount desired at end of the period = 8,900.00/(1+0.06)⁴

PV of the amount desired at end of the period = 8,900.00/(1.06)⁴

PV of the amount desired at end of the period = $7049.63

Thus, the period used = 4 years, Rate used = 6%, the PV factor used = 0.792, and the PV of the amount desired at end of the period = $7049.63.

For the given function, the range of each function would be R = {-15, -7, -3}.

What is the range of the function?

In mathematics, the range of a function can refer to one of two concepts that are closely related: The function's codomain and the function's visual representation A binary relation f between two sets X and Y is a function if for every x in X there is exactly one y in Y such that f relates x to y.

The given function is: h(x) = x - 7 and the domain = {-8, 0, 4}

Now find the range of each function

h(-8) = -8 - 7 = -15

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

For the first point, we would have 9=3k;

So we have k=9/3.

For the second point, we would have 13=4k;

this would mean that k=13/4.

And for 3rd point, we would have 23 =7k;

Checking using proportions shows us that 11/7 does not equal 13/4:

Since this is untrue, k is not a constant and y does not change in direct proportion to x.
