Answer:

The correct option is option (B)

Yes, he will have enough poster board because 10 = 2.5 feet. Then, 2.5 x 2 = 5 square feet .

Step-by-step explanation:

1 foot = 12 inches.

Fabian needs 45 square feet of poster board for an art.

Actually, the area of the poster is 4.5 square feet.

[Since the unit of 4.5 is square feet, so it is unit of area.]

He buys a sheet of poster board with length 30 inches and a width 2 feet.

The units of length and width are not same.

So, first we need to convert the width in inches.

The length of the sheet is = 30 inches

=(30÷12) inches

=2.5 feet.

Total area of the sheet = length×width

=(2.5×2) square feet

= 5 square feet

So, the area of sheet is more than the area of poster.

Yes, he will have enough poster board because 10 = 2.5 feet. Then, 2.5 x 2 = 5 square feet .

Answer:

a) Expected score on the exam is 12.8.

b) Variance 10.24, Standard deviation 3.2

Step-by-step explanation:

For each question, there are only two possible outcomes. Either you guesses the answer correctly, or you does not. The probability of guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:
