Answer:
(b) 0.30 atm
Step-by-step explanation:
Given data
Initial pressure= 1.2atm
Initial volume= 1.0L
Final volume= 4.0L
Final pressure= ???
Let us apply the gas formula to find the Final pressure
P1V1= P2V2
Substitute
1.2*1= x*4
Divide both sides by 4
1.2/4= x
x= 0.3atm
Hence the final pressure is 0.3 atm
4w = 48
Divide each side by 4. (division property of equality)
w = 12
3x+2 (5x-1)=11
3x +10x -2=11
3x+10x=13
13x=13
X=1
Easy
median is the number in the middle when they are arranged in increasing numerical order
example
1,2,3
median is 2 becaus it is in middle
1,4,6,7,8
6 is median
if you have an even amount then average the middle two
1,3,5,7
median is the mean of 3 and 5 which is 4
so
3,5,7,11,23
median is 7 right now
there are an odd amout of numbers
adding 1 will result in even
to find the median of even set of numbers, average the 2 middle ones
right now 7 is center
the mean of 5 and 7 is 6
the mean of 7 and 11 is 9
we want a mean of 9
so add any number greater than or equal to 11
3,5,7,11,12,23 is one option
3,5,7,11,23,50 is another
mean is 9
mean is the average of them
x is the number to be added
6 numbers will be the set since there are 5 now and adding 1 will get 6
(3+5+7+11+23+x)/6=9
(49+x)/6=9
times both sides by 6
49+x=54
minus 49 both sides
x=5
the number added must be 5
to make the median of the 6 numbers 9, add any number greater than or equal to 11, such as 12 or 234
to make the mean 9, add 5 to the set
