5.) A six-sided die is rolled 20 times and the results are recorded as follows: 3 ones, 4 twos, 5 threes, 2 fours, 4
fives, 2 sixes. What is the experimental probability of
rolling a number greater than four? Express your answer
in Fraction, Decimal, and % forms.

There is a 30 % probability of getting  a number greater  than 4.

In  fraction  it 6/20

In decimal it is 0.3

Step-by-step explanation:

The experimental probability is found out by dividing the total favorable outcomes with the total possible outcomes

P (x= 1) = 3/20= 0.15

P (x= 2) = 4/20= 0.2

P (x= 3) = 5/20= 0.25

P (x= 4) = 2/20= 0.1

P (x= 5) = 4/20= 0.2

P (x= 6) = 2/20= 0.1

Now probability greater than 4 = P (x=5) + P(x=6)

                                                   = 4/20 + 2/20= 6/20

                                                    = 0.2+ 0.1= 0.3

So multiplying it with 100 we get = 0.3* 100= 30%

There is a 30 % probability of getting  a number greater  than 4.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
