Answer:
6/5
Step-by-step explanation:
Using the given points (0, 3) and (-2.5, 0) you can substitute it into the slope formula which is y2-y1/x2-x1
In this case, 3 in the first parenthesis is the y2, while 0 in the second parenthesis set is 0.
so,
= substitute in the numbers for the slope formula: 3-0/0-(-2.5)
= reduce the fraction and you get: 1.2
= convert to simplified fraction to get: 6/5
Hope this helps, I did this on a quiz and got the answer right.

Answer:
The probability of picking a black card at random, from a deck with 3 black cards and 7 red ones is 0.3.
Step-by-step explanation:
We will assume that we have 3 black cards and 7 black cards, for a total of 10 cards. Since we are taking one card at random, we can assume that each card is equally likely to be drawn. We have the following event A: The drawn card is a black. We will find the probability of A as counting the number of outcomes that make A to occur and divide it by the total number of possibilities. We are drawing one card, so we have 10 possibilities to be picked. Out of those 10, only 3 cards are black, hence we have 3 possibilites of picking a black card.
Then,
P(A) = 3/10 = 0.3.
