Answer:
I believe that the answer is k=4.
Step-by-step explanation:
Because in order for a new function to be narrower than its parent function, the absolute value of k must be greater than 1 (k > 1), and for a new function to open in the same direction as its parent function, it must be positive, that leaves with only four as our answer.

Answer:
The value of P( A and B ) is 0.08.
Step-by-step explanation:
When two events are independent then the probability of both occurring is equal to the product of probabilities of both events individually,
That is, If X and Y are independent events,
Then, P(X∩Y) = P(X) × P(Y),
or P(X and Y) = P(X) × P(Y),
Here, P(A) = 0.40 and P(B) = 0.20,
Hence, P(A∩B) = P(A) × P(B)
= 0.40 × 0.20
= 0.08
