20 quarts is less than 10 gallons because there are 4 quarts to a gallon which make 20 quarts 5 gallons for it to be 10 gallons it would have to be 40 quarts
Answer:
$10,880
Step-by-step explanation:
15% = 15 ÷ 100 = 0.15
So 15% of 12800 = 0.15 x 12800 = 1920
Therefore, 12800 - 1920 = 10880
OR
12800 x (1 - 0.15) = 10880
60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60
The experimental probability of a certain event is the proability for that event to happen, "suggested" by some empiric experiments, instead of pure theory.
For example, we know that a fair coin has a 50% chance of landing on heads or tails. But if you throw a coin 100 times, with 60 heads and 40 tails, you would say that the probability for heads to show is 60%.
In your exercise, Jenny tried the experiment 50 times, and got a pink tile 18 times. So, according to her results, the probability of pulling a pink tile is
