Step-by-step explanation:
When it asks for range it is asking for the y values so when you plug in numbers such as 0,1,2 into the equation the y values you get are {0,90,180..}
Overall slope can be found by taking the x and y values of the two given points.
((y value of the second point)-(y value of the first point))/((x value of the second point)-(x value of the first point))
Using (1,2) and (-2, 5) you can do this by plugin in the numbers (5-2)/(-2-1)
So the slope will be 3/-3 = -1
Once you find the slope you can use this to find the equation of a line by pluging in values into y=mx + b
m = slope
y = use this from the points given
x = use this from the points given
Answer:
1/30
Step-by-step explanation:
I'm assuming you're asking for three cards being drawn, but if you're actually asking for two cards, the probability is 0. You have no chance of drawing three pink cards if you only draw two cards.
If you mean that three cards are drawn in a row, do the following:
The probability is defined as the number of pink cards / number of all cards.
- The first probability is 4/10, because there are 10 cards, and 4 are pink.
- Next, we don't replace the pink card we draw, so there are 9 cards left, and 3 are pink. The second probability is 3/9.
- Following the same logic, the third probability is 2/8.
We know these are independent events, so we must multiply them together to get the total probability.
4/10 * 3/9 * 2/8 = <u>1/30 is the probability of drawing three pink cards.</u>
