We know P = 1/2
X~B(2, 0.5)
n = 1
2C1 from pascal triangle = 2
P(X=0.5)= 2C1 x 0.5 x 0.5
= 0.5
= 50%
Answer:
$144
Step-by-step explanation:
Let the money which Siti has be x
Therefore, the money June has will be x+240
First condition is that June gave 25% of her money to Siti, So this amount will be deducted from June's money and will be added in Siti's money.
Siti's money = x+ [25%(x+240)] June's money = x+240-[25%(x+240)]
= 1.25x + 60 = 0.75x + 180
Second condition is that Siti now gave 20% of her money to June.This amount will be deducted form Siti's money and added in June's money.
Siti's money = 1.25x+60-[20%(1.25x+60)]
= x+48
June's money = 0.75x +180+[20%(1.25x+60)]
= x+192
Difference between Sitit and June's money = x+192-x-48
= 144
Hence, June has $144 more money than Siti.
Answer:
5.5 Hours
Step-by-step explanation:
Currently, the equation is 60=8.50h+13.25 and h stands for the hours that Sammie worked. So, you need to solve for h by first subtracting 13.25 (his tips) and getting the amount that he received for the hours that he worked.
You should now have 46.75=8.50h
Our final step, is to divide 46.75 by 8.50 to get h by itself and determine the total hours that Sammie worked.
In the end, you should come out with h=5.5, which means that Sammie worked 5.5 hours.
