my answer is in this picture.
All the outcomes are 10 (possibilities)
To pull a quarter (total 3), its probability = 3/10 or 0.3
Now without putting the quarter back, the remaining total is now 9 (because one quarter was pulled out) so the probability of getting a penny is 2/9
But this is a conditional probability a) 1st pull a quarter & 2nd pull a penny
So the total probability is 3/10 x 2/9 =6/90 = 1/15 = 0.067
Answer:
62,832 kilometers
Step-by-step explanation:
The first thing you want to notice is that it's giving you two pieces of one part, if that makes sense. The radius of the earth, and then the distance from the surface of the earth to the orbit. What you want to do is find the circumference of the orbit in relation to the center of the earth. So, as a result, you're going to add those two values together. 6400 + 3600 equals 10,000. Now this is only the radius, but in order to find the circumference, we need the diameter. To find the diameter, you multiply the number by two. 10,000 x 2 is 20,000. Now you multiply this number by pi to find your final answer. This answer is 62,832 kilometers.
Answer:
b g and e
