Answer:
The probability that the red card came from the first stack is:
40%
Step-by-step explanation:
a) Data and Calculations:
Stack Red Blue Total
First 6 5 11
Second 9 0 9
Total 15 5 20
The probability of selecting from the first stack = 50% since equal opportunity is given to the two sacks.
The probability of red card from the first stack = 6/15 = 0.4 = 40%.
b) The probability that the red card came from the first stack is given by the number of red cards in the first stack divided by the number or red cards in the two stacks. This is equal to 6/15 = 0.4 or 40%.
5(1/2)-2(2/3)=11/2-8/3=(11*3)/(2*3)-(8*2)/(3*2)=(3*11-2*8)/6=(33-16)/6=17/6=2(5/6)
so the answer is 17/6 or 2(5/6)
1.(√3)+(√2)
2.(√2)+(√5)
3.(√5)-(√3)
4.(√9)+(√2)
5.(√5)+(√4)
6.(√10)-(√3)
7.(√4)-(√2)
Cuz √[(a+b)±2√(ab)]=(√a)±(√b)
Answer:
x+1/x-1 +1 / x+1/x-1 -1= x
A dozen is 12 jumbo muffins, so 3 dozen is 36 muffins.
We know how much sugar is needed for 8 muffins, and 36 divided by 8 is equal to 4. So we need four times the previous amount.
1.5 tsp x 4 = 6 teaspoons.
