Answer:
151
Step-by-step explanation:
Given the following scores
132,140,130,190,112,200,185, 172,163,151,149 . What isn’t the median ?
Median can be gotten whenever we arrange a set of scores in ascending or descending order.
Arranging the above scores in the ascending order, we have
112,130,132,140,149,151,163, 172,185,190 and 200
Median = 151
Amount of room hannah can paint in an hour = 1/20
amount of room destiny can paint in an hour = 1/16
number of hours = x
1/20x + 1/16x = 1
the reason why this formula is true is, the amount of the room painted in the end should be 1 (the whole room)
4/80x + 5/80x = 1
9/80x = 1
9x = 80
x = 80/9 hours
x = 8.89 hours

Answer:
Step-by-step explanation:
We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720
