Answer:
40
Step-by-step explanation:
The denominators are 4, 5, and 8.
Write the prime factorizations:
4 = 2²
5 = 5
8 = 2³
To find the least common denominator, multiply the prime numbers with the highest exponents.
2³ × 5 = 40
Answer: Last Option

Step-by-step explanation:
In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).
To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.
The horizontal length between 4.71 and 7.4 is:
.
Then notice that the vertical length in this interval is 0.125.
Then the area of a rectangle is:

Where l is the length and w is the width.
In this case we have to:


So
