The width in only one side is 56ft and in both it is 112ft. The length in only one side is 61ft and in both sides it is 122ft.
To solve this question we will use the following diagram:
From the diagram, we get that the diameter of the semicircle is 8cm.
The perimeter of the figure is:
Substituting π=3.14 and simplifying we get:
Now, the area of the given figure is the area of the rectangle plus the area of the semicircle:
Substituting π=3.14 and simplifying we get:
Answer:
Answer:
Yes they are independent events
Step-by-step explanation:
In order to solve this, you need to first know the definition of probability of independent event.
two events are independent if the incidence of one event does not affect the probability of the other event. When that occurs, the expression or formula to calculate is the following:
P(A∩B) = P(A) * P(B)
So, in order to see if A and B are independent, let's see how the calculations do with the data provided
P(A∩B) = P(A) * P(B) = 1/4 * 2/5 = 2/20 = 1/10
Therefore, A and B are independent events
