Answer:
There are 73815 ways of selecting 4 of the lottery numbers.
Step-by-step explanation:
The total amount of ways to pick 4 numbers from a set of 38 ignoring the order is given by the combinatorial number of 38 with 4, denoted by 
, which is
Therefore, there are 73815 ways of picking 4 of the numbers.
Prime factorization of 160 = 2 x 2 x 2 x 2 x 2 x 5
The answer is d because the centroid stems from medians in a triangle
20-12 1/3=7 2/3 or 23/3. so there is a total of 23/3 ft available. We then take half of that for each side. 1/2 of 23/3= 1/2*23/3= 23/6
Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u
Speed of current = v
Let distance between A & B = 100 km
Time taken in downstream = 32 hours
u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours
u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045
v = 0.5205
Now the time taken by the un powered raft to cover this distance
Because un powered raft travel with the speed of the current.
T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
