Total perimeter is 522 ft. I will guess the gym is a big rectangle.
Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W
We know 80 ft wide. so now we plug and chug the equation we came up with
P=522 ft
P=2L+ 2(80)
522=2L+ 160
L= 181
hope that helps
Answer:
187
Step-by-step explanation:
E and F are two events and that P(E)=0.3 and P(F|E)=0.5. Thus, P(E and F)=0.15
Bayes' theorem is transforming preceding probabilities into succeeding probabilities. It is based on the principle of conditional probability. Conditional probability is the possibility that an event will occur because it is dependent on another event.
P(F|E)=P(E and F)÷P(E)
It is given that P(E)=0.3,P(F|E)=0.5
Using Bayes' formula,
P(F|E)=P(E and F)÷P(E)
Rearranging the formula,
⇒P(E and F)=P(F|E)×P(E)
Substituting the given values in the formula, we get
⇒P(E and F)=0.5×0.3
⇒P(E and F)=0.15
∴The correct answer is 0.15.
If, E and F are two events and that P(E)=0.3 and P(F|E)=0.5. Thus, P(E and F)=0.15.
