Answer:
B
Step-by-step explanation:
Area of a trapezoid = (1/2)*(base1+base2)*height
Area = (1/2)*(15+7)*height
DC is 7 which means EF is also 7.
AB = 15
AB - EF = AE + FB = 8
And AE = FB we know that AE is 8/2 = 4
We were given AD = 5. We have a 3-4-5 right triangle and therefore DE is 4. The height of the trapezoid is 3 ft.
Area = 1/2 (15+7)*(3)
Area = (1/2)*22*3
Area = 11 * 3
Area = 33 ft^2
Your answer is B
Answer: i think is C
Step-by-step explanation: Experimental probability is the probability of what actually happens in the given experiment.
We know that a fair six-sided cube is rolled 60 times and the outcome 2 has occurred 15 times out of 60 times.
Therefore, the experiment probability in the given experiment is:
Experimental probability of rolling 2
Now, the theoretical probability is the probability of what is expected from the random experiment. We know that a cube has 6 sides and the theoretical probability of getting 2 is given below:
Theoretical probability of rolling a 2
Therefore, the correct option is:
The experimental probability of rolling a 2 is and the theoretical probability of rolling a 2 is .
