Answer:
X = 1
Y = 5
Step-by-step explanation:
we have to figure out what x and y = that make both answers correct
3 x 1 = 3
3 + 5 = 8
That means that the first equation is right with X = 1 and Y = 5
Let's see the second equation
5 x 1 = 5
5 + 5 = 10
That means both equations are right so the answer would be
X = 1 and
Y = 5
Going to the right or left when doing translation effects the x coordinate. In this case, the x coordinate is 14. Since we are moving 6 units to the left, we must subtract 6 from 14. Moving to the left is negative and moving to the right is positive.
14 - 6 = 8
The answer is (8,-12)
a. "Chocolate" and "Adults" (whatever those mean) will be independent as long as
"Chocolate" has the marginal distribution given by the second column, with a total probability of
. Similarly, "Adults" has the marginal distribution described by the third row, so that
. Then
Meanwhile, the joint probability of "Chocolate" and "Adults" is given by the cell in the corresponding row/column, with
.
The probabilities match, so these events are indeed independent.
Parts (b) and (c) are checked similarly.
b. Yes;
c. Yes;
