Answer: y = 3x -2

Step-by-step explanation:

1) slope formula

y2 - y1 / x2 - x1

2) find the y's and x's

y2 = 10

y1 = -2

x2 = 4

x1 = 0

3) plug them into the equation

10 - (-2) / 4 -0

10+2/4

12/4

4) simplify

slope = 3

5) write out equation

y = 3x + b

6) plug in coordinates

(0,2)

-2 = 3(0) + b

7) find the y intercept

-2 = b

8) plug in y intercept

y = 3x -2

It will take 3 years for Korey to see an overall profit in his business.

A percentage is a number or ratio that represents a fraction of 100. 

We have,

Cost of the store to open = $12500

Cost of the operational cost = $8000

Profit store makes each year = $12000

Profit increase each year = 6%

Profit = Income - Total cost

First-year:

Profit = 12000 - (12500 + 8000) = -8500

There is no profit in the first year.

2nd year:

Profit = 2 x (12000 + 6% of 12000) - (12500 + 2 x 8000)

         = 25440 - 28500

         = -3060

There is no profit in the second year.

Third-year:

Profit =  3 x (12000 + 6% of 12000) - (12500 + 3 x 8000)

         =  38160 - 36500

         = 1660

We see that there is a profit of 1600 in the third year.

Thus,

It will take 3 years for Korey to see an overall profit in his business.

The integer -5 represents Kyle’s location relative to Nadim’s location on the game board.

It is given in the question that Kyle and Nadim are on the same space on a board game they are playing. Kyle moves back 2 spaces in one turn and moves back 3 more spaces in his second turn while Nadim remained in the same place.

We have to find the integer that represents Kyle’s location relative to Nadim’s location on the game board.

We usually denote going ahead by the positive sign and the going back by the negative sign.

Hence, Kyle moving back 2 spaces and then again moving back 3 spaces is equal to moving back 5 spaces which will be represented by the integer -5.

8400000cm

84 kilometer is 8400000 centimeter.

Here given 84 km ,

We know that 1 km = 1000 meter

               so 84 km  = 84 x 1000 meter

                                 = 84000 meter

 and 1 meter = 100 cm

 so here 84000 meter = 84000 x 100 cm

                                       = 8,400,000 Centimeters

∴ 84 km = 8400000cm

1. F(x) represents the total cost function for renting a Popcorn machine.

2. The 40 in the equation represents the Fixed Cost per day of the rental.

3. The 0.15 represents the variable cost per hour.

4. The x represents the number of hours the machine is rented.

A function is a mathematical expression, rule, or law defining the mathematical relationship between the independent variable and the dependent variable.

Mathematical functions are used to define the mathematical relationships that show how the dependent variable can be determined, given an independent variable.  They are written with the equal sign (=).

Thus, we can conclude that the rental cost function ƒ (x) = 40 + .15x shows the total amount that a customer would be charged each day for renting a Popcorn machine.

"not more" means "less than or equal to". We just have to use the inequality sign "less than or equal to" which means 5 is less than or equal to x.

Having said that, we can express the statement as follows

The probability that if a malpractice suit is filed, it originated in hospital 1 = P(B1|A) =

To solve this problem we will use Baye's theorem which states

P(B1 |A) = P(A/B1)P(B1) / P(A|B1)P(B1) + P(A|B2)P(B2) + P(A|B3)P(B3)       (1)

where P(A|B) is the probability of event A occurring given that event B has already taken place.

Probability of hospital 1 having the case = P(B1) = 50

Probability of hospital 2 having the case = P(B2) = 30

Probability of hospital 3 having the case = P(B3) = 20

Probability of case resulting in malpractice in hospital 1= P(A/B1) =0.001

Probability of case resulting in malpractice in hospital 2= P(A/B2) =0.005

Probability of case resulting in malpractice in hospital 3= P(A/B3) =0.008

The probability that if a malpractice suit is filed, it originated in hospital 1 = P(B1|A)

Using equation (1)

P(B1|A) = (0.001)(50) / (0.001)(50) + (0.005)(30) + (0.008)(20)

          = 0.05 / ( 0.05 + 0.15 + 0.16 )

          = 0.05 / 0.36

          = 0.138

B. |-12.7| = 12.7,    |-11 1/4| = |-45/4| = 45\4

B Optional 45/4 = 11.25 as decimal form

Step-by-step explanation:

For the mixed fractions you have to divide it. For the whole fraction

11 1/4    

1. 11 x 4=44

Then add the 1. 44+1=45

The denominator doesn't change

The vertices of parallelogram MNOP after a rotation of 180° are: M' (-1, -7), N' (-8, -5), O' (-4, -2), and P' (3, -4).

A counterclockwise rotation of 270° to triangle GHI would produce an image with this vertices: G' (-2, 0), H' (-6, -7), and I' (-8, -3).

In this exercise, you are required to rotate parallelogram MNOP by 180° and triangle GHI by 270° in a counterclockwise direction. In Geometry, the rotation of parallelogram MNOP 180° about the origin in a clockwise or counterclockwise direction would produce a point that has the vertices (-x, -y):

(x, y)                           →               (-x, -y)

Point M' = (1, 7)        →    Point M' = (-(1), -(7)) = (-1, -7).

Point N' = (8, 5)       →    Point N' = (-(8), -(5)) = (-8, -5).

Point O' = (4, 2)       →    Point O' = (-(4), -(2)) = (-4, -2).

Point P' = (-3, 4)       →   Point P' = (-(-3), -(4)) = (3, -4).

In Geometry, the rotation of triangle GHI by 270° about the origin in a counterclockwise direction would produce a point that has the vertices (y, -x):

(x, y)                           →               (y, -x)

Points at G = (0, -2)   →  Points at G' = (-2, 0)

Points at H = (7, -6)   →  Points at H' = (-6, -(7)) = (-6, -7).

Points at I = (3, -8)   →  Points at I' = (-8, -(3)) = (-8, -3).
