A is the answer, because the highest exponent is 2.

<u>quadratic</u>

A's expression foiled would be 2x^2 + x - 6

B's expression foiled would be 3x - 12, where the exponent on x is only 1.

D's expression foiled would be x^3 - x^2 - 12x, where the exponent on x is 3.

Ratling [72]

Answer:

The probability that the hail storm will happen on a Saturday is 0.1667.

Step-by-step explanation:

The month of June started on Friday.

Then June 2 is a Saturday.

Remaining 28 days.

Each week has 7 days.

There will be 4 full weeks for the month of June.

So there will be 4 more Saturdays.

Thus, there are a total of 5 Saturdays in the month of June.

Compute the probability that the hail storm will happen on a Saturday as follows:

P(hail-storm)=\frac{n(Saturdays)}{Total\ no.\ of\ days} =\frac{5}{30}= 0.1667

Thus, the probability that the hail storm will happen on a Saturday is 0.1667.
