If it snows tomorrow, the probability is 0.5 that John will practice his guitar. If it does not snow tomorrow, there is only a 0.4 chance that John will practice. Suppose the chance of snow tomorrow is 60% What is the probability that John will practice his guitar?

P(John will practice) =

0.24

Step-by-step explanation:

60% is 0.6

0.6x0.4=0.24

A. F(x)is an even function so both ends of the graph go in the same direction.

D. The leading coefficient is negative so the left end of the graph goes down.

Step-by-step explanation:

Even function:

For every value of x, f(x) = f(-x)

In this question:

We are given the following function:

Testing if it is even:

Since f(1) = f(-1), it is even.

Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.

Options C and D:

The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.
