Answer:

  • changes by 120 for each copy
  • is 1800 if none are sold

Step-by-step explanation:

Let's look at the second question first.

x is the number of copies Chau sells. If he doesn't sell any copies, then x = 0. To find Chau's pay, we use x=0 in the equation, and solve for y.

  120×0 +1800 = y

  0 +1800 = y

  1800 = y

Chau's pay when he sells no copies is $1800.

__

If Chau sells 1 copy, then his pay is ...

  120×1 +1800 = y = 1920 . . . . . . . use the equation with x = 1

The increase in Chau's pay is 1920 -1800 = 120.

Chau's pay changes by $120 for each copy he sells.

The probability that a 4 shows up is 0.20 and the proportion of 3's rolled is 0.467

<h3>The probability that a 4 shows up</h3>

From the list of numbers, we have:

  • Sides = 5 i.e. numbers 1 to 5
  • n(4) = 1 i.e. sides labelled 4

The probability that a 4 shows up is then calculated as:

P = n(4)/Sides

This gives

P = 1/5

Evaluate

P = 0.2

<h3>The proportion of 3's rolled</h3>

In the list of numbers, we have:

  • Total = 15
  • Number of 3's = 7

The proportion of 3's rolled is then calculated as:

P = Number of 3's/Total

This gives

P = 7/15

Evaluate

P = 0.467

Hence, the proportion of 3's rolled is 0.467

point slope form is y-y1=m(x-x1)

from (6,1) y1 = 1 and x1 = 6

slope is given as -3

 so you should have y=1 =-3(x-6)

Think of 2 times 2
You would duplicate 2 two times
