Answer:
y = -2x - 6
The y-intercept will be (0,-6)
One point will be at (1,-8)
The line will go downward since it is a negative slope
Step-by-step explanation:
y−2=−2(x+4)
Distribute
y - 2 = -2x - 8
Move the constant to the other side
y - 2 = -2x - 8
+2 = +2
y = -2x - 6
Answer:
0.4
Step-by-step explanation:
The table with correct formatting is attached in the image below.
We have to find P(Y | B). This is a conditional probability i.e. probability of Y given B.
The formula of conditional probability for two event A and B is:
So, for the given case, the formula would be:
P(Y ∩ B) indicates the probability of Y and B occurring together. Y and B occur together 34 times out of total of 324, so:
P(B) indicates the probability of occurrence of B. B occurs 85 times in a total of 324. So,
Using these values in the formula of conditional probability, we get:
Thus, the value of P(Y|B) is 0.4
