Let the total number of people surveyed by y.
we can solve this by using algebra.
to find the percentage of a number in terms of decimals or integers, just multiply the total by the percentage,
so with this question,
y x 40% = 20
shift x40% to the other side and turn it into /40%
y = 20 / 40%
change the percentage into decimals for easier calculations,
y = 20 / 0.4
y = 50
therefore, the answer to this is 50 people.
Answer:
Step-by-step explanation:
47 and half .................
Becase 3x9=27 27/100 would be the awnser and is already in simplest form
Well, when you flip a coin, there's a 50/50 chance it's going to land on heads or tails. so if you flip a coin 4 times there's a small chance it's going to be on heads and three tails.
some probabilities are-
-all four heads
-all four tails
-two heads two tails
-3 heads one tail
-1 tail 3 heads
so, therefore there is a 1/5 chance that it is going to be one heads and three tails. I hope this helps
