It will take Mary 6 1/4 hours to walk 25 miles at this rate.
Divide the total number of miles by the number of miles per hour.
25/4 hours
This fraction cannot be simplified, but it can become a mixed number.
6 1/4 hours
2nd option or 3rd option hope I evened it out a bit
Answer:
Step-by-step explanation:
Measure of an arc is equal to the measure of its corresponding central angle.
Here, measure of the corresponding central angle of the arc EF is 146°
Therefore,

Answer: The correct option is (1) Dependent.
Step-by-step explanation: For two events, we are given the following values of the probabilities :
P(A ∩ B) = 0.20, P(A) = 0.49 and P(B) = 0.41.
We are to check whether the events A and B are independent or dependent.
We know that
the two events C and D are said to be independent if the probabilities of their intersection is equal to the product of their probabilities.
That is, P(C ∩ D) = P(C) × P(D).
For the given two events A and B, we have

Therefore, the probabilities of the intersection of two events A and B is NOT equal to the product of the probabilities of the two events.
Thus, the events A and B are NOT independent. They are dependent events.
Option (1) is CORRECT.
