The answer is B. I have this question before when i was in 3rd grade once. u must be in k12
The average speed of the snowmobile can be obtained by using the formula: speed = distance/time which was also given in the problem statement. This means that the average speed refers to how far you have traveled in a period of time. In this case, the snowmobile traveled 32 miles in 213 hours. We then simply divide the distance, 32 miles, by the time it took for the snowmobile to travel such distance which is 213 hours. The average speed of the automobile is calculated to be 0.1502 miles per hour. When rounded off to the nearest tenth, the final answer is then 0.2 miles per hour.
The answer is 18, the answer is always just the number in the brackets( hope this helps)
Probability that the first 2 of the friends to show up to the movie are friends he has known since kindergarten but the third not is 1/10
Total friends = 10
Friends from kindergarten = 4
Probability is the chance that a given event will occur. Probability of an event lies within 0 to 1
P(E) = Favourable outcomes / Total outcomes
Probability of getting 1st friend from kindergarten = 4/10
Probability of getting 2nd friend from kindergarten = 3/9
Probability of getting 3rd friend not from kindergarten = 6/8
Since all these probabilities are independent, We can use Multiplicative identity. Thus,
Required probability is 4/10 * 3/9 * 6/8
= 1/10
Thus, Probability that the first 2 of the friends to show up to the movie are friends he has known since kindergarten but the third not is 1/10
