Answer:
x=112
Step-by-step explanation:
x/2-18=38
first add +18
x/2=56
now multiply by 2
x=112
Answer: OPTION D.
Step-by-step explanation:
You have the expressions given in the problem:
To find the product of both expression you must multiplicate them.
You must multiply the numerators of both expression and the denominators of both expression.
Keeping the above on mind, you obtain that the product is:
Answer:
The range and mean will increase - False
(because only range will increase, mean will decrease)
The mean and median will decrease - True
The mean will decrease but the median will stay the same - False
(Both of mean and median will decrease)
An outlier is more likely to change the median than the mean - False
(An outlier is more likely to change the mean than the median)
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
