P(A) = probability of event A, P(B) = probability of event B
P(A) = x is given to us
P(B) = y is also given
--------------------------
If A and B are independent, then neither event affects the other. If we know A happens, then that doesn't change the probability of B happening (vice versa).
So that means P(A|B) = P(A) = x and P(B|A) = P(B) = y
This points to the answer being P(B|A) = y which is choice A or the first answer choice
note: P(A|B) is read as "probability of A given that B has happened". It is known as conditional probability. The symbol between the A and B is not the letter i or L, it is a vertical pipe symbol to separate the letters.
Answer:
y = 4x - 7
Step-by-step explanation:
y = mx + b where m = slope and b = y-intercept
In this case m = 4 and y-intercept b = -7
Equation
y = 4x - 7
Answer:
5 dollars more
Step-by-step explanation:
Right now, Jake is using a material that gives him 27 dollars of profit per deck. If he switches to a new material, the profit that he gets is expressed by the function y = 32x. To make this a bit easier to understand, let's switch out y and x for some easier words.
profit = (number sold)*32
This function shows that for each deck with the new material, Jake will get 32 dollars profit. Since the question asks for how many more dollars, we can get the answer by
32 - 27 = 5.
If you still don't understand it, you can think of his old material in a function too:
y = 27x or profit = (number sold) * 27.
Comparing that one with the one above with the new material, we can tell that 32 represents the profit per deck.
Answer:
88 are boys
Step-by-step explanation:
220 times 3/5 = 132
220-132 =88
