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;
4 1/2 is the exact answer. 5 is the estimate.
Answer:
2
Step-by-step explanation:
The Fundamental theorem of algebra states that a polynomial of degree n has n roots. These can be real or complex.
A quadratic is of degree 2 and has 2 roots.
Answer:
you need to have values to solve for this
Step-by-step explanation:
Answer:
f'(×)=(y+2)^1/5 -5
Step-by-step explanation:
let y=-2+(x+2)
(y+2)^1/5=(x+5)
f'x=(y+2)^1/5 -5
