Answer:
60/100 and x/20 and x=12
Step-by-step explanation:
60 % of 20
60/100 = x/20
cross product
60 * 20 = 100x
divide by 100
1200/100 =x
12=x
Answer:60/100 = x/20 x= 12
hope it's right
We have to find the expected value for the PlayBall lottery.
The price of the ticket = $1
Prize amount = $250
If a player wins, he will be winning $249 as the price is not paid back along with the prize amount. He is spending $1, getting back $250, so the net amount he is getting back is $249.
Now we have to find the probability of winning and losing.
Number of letters from A to T = 20
Number of digits from 0 to 9 = 10
Probability of picking up the same letter that was picked on that day = 1/20
Probability of picking up the same number that was picked on that day = 1/10
Thus, the Probability of picking up the same letter and same number that was picked on that day =

Thus, the probability of winning = 1/200
The probability of losing =

The expected value E for the PlayBall lottery will be:
Thus, the option C gives the correct answer
Answer:
256 m and 3840 m²
Step-by-step explanation:
The 3 part of the ratio represents 48 m , then
48m ÷ 3 = 16 m ← value of 1 part of the ratio, so
5 parts = 5 × 16 m = 80 m
Then breadth = 48 m and length = 80 m
perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m
area = lb = 80 × 48 = 3840 m²
Answer: 10
Why?
3*9+2y=47
3*9= 27
27+2y=47
47-27= 20
2y=20
20/2=10
Y=10
Hope this helps :D
Answer: x = 8
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
