The required probability of winning is given as 0.32.

Given that,
Playing a game that involves tossing a single die. If roll one, you win $100. If you roll a 2, you win $50. roll anything else, you lose $25.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
total number of sample spaces = 6
total of favorable outcome = 2
Probability fo the winning = 2 / 6 = 0.3333 or 0.32

Thus, the required probability of winning is given as 0.32.

Slope of Parallel line is 3/4

Slope of Perpendicular line is -4/3

What is Slope of Line?

The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x).

Solution:

General Form of Line: y = mx + c

here, m is the slope

4y = 3x + 6

y = 3/4x + 3/2

Answer:

$5000

Step-by-step explanation:

Let x represent the amount invested at 6% interest. Then 7000-x is the amount invested at 7% interest

6% interest = 6/100 = 0.06 in decimal

7% interest = 7/100 = 0.07

Interest earned from depositing x dollars at 6% = 0.06x

Interest earned from depositing 7000-x at 7% = 0.07(7000-x)

Total interest earned would be
0.06x + 0.07(7000-x)

Since this must be at least $440 we get the equation interest as

0.06x + 0.07(7000-x) = 440

Simplifying
0.06x + 0.07 x 7000 - 0.07x = 440

0.06x + 490 -0.07x = 440

-0.01x = 440 - 490

-0.01x = -50

Multiply both sides by -1

==> 0.01x = 50

==> x = 50/0.01 = 5000

So max amount that can be invested at 6% interest = $5000

Answer:

1/4 and -20

Step-by-step explanation:

"Slope" just means the change in y divided by the change in x. In the first graph, the slope is the change in depth divided by the change in hours.

Using the equation, slope = (y - y1)/(x - x1), you can plug in 2 points and solve. I see that the line goes through the points (4,1) and (8,2), so I'll use these. Make sure that (x,y) are from the same point and (x1,y1) are from the same point.

slope = (2 - 1)/(8 - 4)

slope = 1/4

You can do the same process for the second graph but you'll use different points. I see the points (2,80) and (4,40), so I'll use those.

slope = (40 - 80)/(4 - 2)

slope = -40/2

slope = -20

Answer:

function 2

Step-by-step explanation:

function 1 has a slope of 8/7 which is equal to 0.75 and function 2 has a slope of 1 so function 2 is greater than function 1.

Answer: <

Step-by-step explanation:

One number is less than another number if their difference is less than zero.

Since x=2y-4 - 0.75 = -0.75 which is less than zero, x=2y-4 is less than 0.75

Therefore, x=2y-4 is 0.75 less/lower than 0.75

The standard form equation for the line through the points (3,-4) and (6,-2) is  -2/3 x + y = 4.

What is the equation of the line passing through the two-point?

To find the equation for the line through two points we can use the formula:

y - y1 = m(x - x1)

where (x1, y1) is one of the points, and m is the slope of the line. The slope of the line is equal to the change in y over the change in x, which can be calculated as:

m = (y2 - y1) / (x2 - x1)

where (x2, y2) is the other point.

Substituting the given points and the formula for the slope into the formula for the equation of the line, we get:

y - (-4) = ((-2) - (-4)) / (6 - 3) (x - 3)

This simplifies to:

y + 4 = -2/3 (x - 3)

To write the equation in standard form, we can distribute the -2/3 and then rearrange the terms:

-2/3 x + y = 4

Hence, the standard form equation for the line through the points (3,-4) and (6,-2) is  -2/3 x + y = 4

Find the equation of lines m, n and p

                    The equation of line:

Answer:

5) No the lines are not parallel because in order for this to be true, the slopes have to be equal. Line m has a slope of 2/3 and line n has a slope of 3/5. Both slopes are not equal so it is not parallel

6) No, m is not congruent to p

7) No, n is not congruent to p

After the markup, the selling price of the item will be $39.

We know that a store owner decides to mark up all items by 30%, so basically we need to increase all the costs by 30%.

If the original cost is C, then the cost after the mark up will be:

P = C*(1 + 30%/100%)

P = C*(1 + 0.3)

P = C*(1.3)

In this case, we want to find the selling price P for an object whose original cost C is $30, then we can replace C in the equation above so we get:

P = $30*1.3 = $39

The selling price P  is $39.

The least polynomial with degree 3 is equal to f(x) = x³ - (8 / 7) · x² + 4 · x - 32 / 7.

In this problem we need to determine the least polynomial such that its degree is 3 and - i 2 and 8 / 7 are roots of the resulting expression. By quadratic formula, the roots - i 2 is along with its conjugate i 2 to obtain a quadratic equation with real coefficients. The factor form of the cubic polynomial is:

f(x) = a · (x - r₁) · (x - r₂) · (x - r₃)

Where:

And we must determine the standard form of the polynomial by means of algebra properties. This form is shown below:

f(x) = a · x³ + b · x² + c · x + d

Where a, b, c, d are real coefficients.

First, write the polynomial in factor form: (a = 1)

f(x) = (x - 8 / 7) · (x + i 2) · (x - i 2)

f(x) = (x - 8 / 7) · (x² + 4)

What is arithmetic?

Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, involution, and extraction of roots.

Main Body:

We use the Inventory identity to solve for ending inventory

Beginning Inventory + Purchase = ending Inventory + used

20,800 +159,000 = ending inventory + used materials

used materials:

135,600 direct

12,400 indirect

148,000 total materials used

20,800 + 159,000 = Ending Inventory + 148,000

20,800 + 159,000 - 148,000 = Ending Inventory

Ending Inventory = 31,800

Ages of Tristan, Richard, and Pablo are in the order 6:7:4.

Detailed explanation:

Pablo is six years younger than Richard, seven years older than Tristan, and five years younger than Richard.

We can multiply the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age to determine the ratio of Tristan's age to Richard's age before determining the ratio of Tristan's age to Pablo's age.

These ratios add up to 6/7 * 5/4 = 30/28.

Pablo's age to Richard's age is 6:7, thus we may multiply this ratio by the age of Richard by Tristan's age to determine the age of Pablo, Richard, and Tristan.

Thus, the ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.
