The probability that the winner will pull out at least one $100 bill is 7/36, or 19.4%.

The probability of an event occurring is determined by the number of favorable outcomes divided by the total number of possible outcomes.

In this problem, the favorable outcome is that the winner will pull out at least one $100 bill, while the total number of possible outcomes is the number of ways to select 4 bills from the hat, which is 36.

Thus, the probability of the winner pulling out at least one $100 bill is calculated by dividing the favorable outcome by the total number of possible outcomes.

Since there are 7 $100 bills in the hat, the favorable outcome is 7. The total number of possible outcomes is 36, which is calculated by using the formula nCr, where n is the total number of objects and r is the number of objects selected.

In this case, n = 36 and r = 4, so the equation is 36C4.

Thus, the probability that the winner will pull out at least one $100 bill is 7/36, or 19.4%.

The correlation coefficient between the minutes the actor appeared shirtless in a film and the film's opening weekend gross is 0.75.

In this scenario, the minutes shirtless (x) would be plotted on the x-axis of the scatter plot while the open weekend gross (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the minutes shirtless (x) and the open weekend gross (y), an equation for the linear regression is given by:

y = 10.83 + 0.86x

Correlation coefficient, r = 0.7488571925 ≈ 0.75

In conclusion, we can logically deduce that there is a strong correlation between the data because the correlation coefficient (r) is approximately greater than 0.7;

Okay, here are the steps to solve this system of linear equations:

3x1 + x2 + 2x3= 6

4x1 - 3x2 + 5x3 = 8,

2x1 + x2 + 3x3 = 10

1) Add 4 times the first equation to the second equation:

7x1 + 2x2 + 7x3 = 22

2) Add -2 times the first equation to the third equation:

5x1 - x2 + 5x3 = 12

3) Divide both sides by 5 to get:

x1 = 2

x2 = -2

x3 = 1

Therefore, the solution to the system is:

x1 = 2

x2 = -2

x3 = 1

Let me know if you have any other questions!

The value of x in the equation is 2.10.

The exponential equation above can be solved as follows:

[tex]8^{\frac{4}{x} } = 53[/tex]

Therefore, let's log both sides

log [tex]8^{\frac{4}{x} }[/tex] = log 53

Hence,

4 / x log 8 = log 53

divide both sides by log 8

4 / x = log 53 / log 8

4 / x = 1.7242758696 / 0.90308998699

4 / x = 1.9092439208

To find the coterminal angle for a rotation of -757°, we can add or subtract multiples of 360° until we find an angle between 0° and 360° that is coterminal with -757°.

Adding 360° multiple times:

-757° + 360° = -397° (not coterminal)

-397° + 360° = -37° (not coterminal)

-37° + 360° = 323°

Therefore, the coterminal angle for -757° is 323°.

To find the quadrant in which 323° lies, we can note that 323° is between 270° and 360°, which means it lies in the fourth quadrant.

To find the reference angle for 323°, we can subtract 360° from 323° until we get an angle between 0° and 90°:

323° - 360° = -37° (not in the correct range)

-37° + 360° = 323°

So the reference angle for 323° is 37°.

The probability of the odds of the rugby team winning its next match is

12 to 11.

We have,

The probability of an event happening is defined as the ratio of the number of favorable outcomes to the total number of outcomes.

The odds against an event happening are defined as the ratio of the number of unfavorable outcomes to the number of favorable outcomes.

If the probability of the rugby team winning its next match is 11/23, then the probability of the team losing its next match is:

= 1 - 11/23

= 12/23.

The odds against the rugby team winning its next match are the ratio of the number of unfavorable outcomes (losing the match) to the number of favorable outcomes (winning the match), which is:

12/23 : 11/23

We can simplify this ratio by dividing both the numerator and denominator by 11:

(12/23) ÷ (11/23) : (11/23) ÷ (11/23)

12/11 : 1/1

The three (3) true statements about the quadratic function and its graph include the following:

A. The value of f(–10) = 82

B. The graph of the function is a parabola.

D. The graph contains the point (20, –8).

Generally speaking, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. For this quadratic function, the graph is a upward parabola because the coefficient of x² is positive and the value of "a" is greater than zero.

Next, we would determine the other true statements about the graph of this quadratic function:

At point (-10, 82), we have:

Quadratic function, f(x) = 1/5 x² – 5x + 12

Quadratic function, f(x) = x²/5 – 5x + 12

Quadratic function, f(-10) = -10²/5 – 5(-10) + 12

Quadratic function, f(-10) = 82

At point (20, -8), we have the following:

Quadratic function, f(x) = 1/5 x² – 5x + 12

Quadratic function, f(x) = x²/5 – 5x + 12

Quadratic function, f(20) = 20²/5 – 5(20) + 12

Quadratic function, f(20) = -8

In conclusion, we can logically deduce that the graph of this quadratic function does not contain the point (0, 0) as shown in the image attached below.

The measure of ∠LPN is 57°.

An arc is a segment of a circle in geometry that is typically defined by two endpoints and the arc itself, which is the collection of all points on the circle that are situated between the two endpoints.

The subtendency of an arc can be measured by measuring its central angle.

Since angles inscribed in the same arc are congruent, we have:

m(arc LP) = m(arc NP) = 102° + 144° = 246°

Now, using the fact that the sum of the measures of the arcs of a circle is 360°, we have:

m(arc LM) + m(arc LP) + m(arc NP) + m(arc MN) = 360°

Substituting the known values, we get:

m(arc LM) + 246° + m(arc MN) = 360°

Simplifying, we have:

m(arc LM) + m(arc MN) = 114°

But angles inscribed in the same arc are congruent, so we have:

m(∠LPN) = (m(arc LM) + m(arc MN))/2

Substituting the value we found for m(arc LM) + m(arc MN), we get:

m(∠LPN) = 114°/2 = 57°

The unit sales of product A at the monthly break-even point is 193,750 units.

To determine the unit sales of product A at the monthly break-even point, we need to calculate the total contribution margin that covers the monthly fixed costs of $387,500.

Given that the unit contribution margin for product A is $2 and the unit selling price for product A is $5, we can calculate the contribution margin ratio for product A as follows:

Contribution Margin Ratio for Product A:

= (Unit Contribution Margin for Product A) / (Unit Selling Price for Product A)

= $2 / $5

= 0.4

40%

Now, let's consider the sales ratios given in the problem statement. It states that the company sells two units of A for each unit of B, and three units of B for each unit of C. This means that the sales ratio for product A to product B is 2:1, and the sales ratio for product B to product C is 3:1.

Let's assume that the unit sales of product A at the monthly break-even point is "x". Then, the unit sales of product B would be "2x" (based on the sales ratio of 2:1 between A and B), and the unit sales of product C would be "6x" (based on the sales ratio of 3:1 between B and C).

The total contribution margin for product A at the monthly break-even point can be calculated as follows:

Total Contribution Margin for Product A = (Unit Contribution Margin for Product A) * (Unit Sales of Product A at Break-Even Point)

= $2 * x

Since the monthly fixed costs are $387,500, we can set up the equation for the break-even point as follows:

Total Contribution Margin for Product A = Monthly Fixed Costs

$2 * x = $387,500

Now we can solve for x, the unit sales of product A at the monthly break-even point:

$2 * x = $387,500

x = $387,500 / $2

x = 193,750
