Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph.

Delicious77 [7]

First you want to find the slope. Pick any two points. (150,200) and (300,100) x2-x1/y2-y1
300-150=150
100-200=-100
150/-100= -1.5
Y=mx+b. M is the slope b is the y intercept
Y=-1.5x+300

let the number of shots represent x

0.30x = 5...divide borh sides by 0.30

x = 5/0.30

In the following you may leave your answer as a binomial or multinomial coefficient. In each case give a brief justification for

Simora [160]

Answer: a) 792 ways b) 13⁷.

Step-by-step explanation:

Since we have given that

Number of apples to be given = 5

Number of bananas to be given = 7

Number of people = 12

So, Number of ways that each person gets a pieces of fruit is given by

$\dfrac{12!}{7!\times 5!}\\\\=792\ ways$

b) If the number of people = 13

Number of apples to be given = 7

So, Number of ways would be

$13\times 13\times 13\times 13\times 13\times 13\times 13\\\\=13^7$

Hence, a) 792 ways b) 13⁷.

What is the midpoint of EF If E has the coordinates of (2,4) and F has coordinates of (6,8)

allsm [11]

Answer:

$\boxed {\boxed {\sf (4,6) }}$

Step-by-step explanation:

The midpoint formula is:

$(\frac{{x}_{1}+{x}_{2}}{2},\frac{{y}_{1}+{y}_{2}}{2} )$

where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.

We are given the points: (2,4) and (6,8). Therefore,

$x_1=2\\y_1=4 \\x_2=6 \\y_2=8$

Substitute the values into the formula.

$(\frac{2+6}{2},\frac{4+8}{2})$

Find the x coordinate first.

Add 2 and 6: 2+6=8
Divide by 2: 8/2=4

$(4, \frac{4+8}{2})$

Find the y-coordinate next.

Add 4 and 8: 4+8= 12
Divide by 2: 12/2=6

$(4,6)$

The midpoint of EF is (4,6)
