Answer:
a.) False
b.) True
c.) True
d.) False
Step-by-step explanation:
a.) This choice is false because you can't know for sure what will happen in the future. The statement uses the word "will" which suggests that you know for sure what will occur. However, the statement also says "tomorrow" and since no one can tell the future, this statement is false.
b.) This statement is true. Let's set up a ratio to solve this problem.
People who payed using cash : Customers
20 : 80
The statement asks about 40 customers, so we need to divide both sides by 2 in order to make the information relevant.
20 : 80
/2 /2
10 : 40
This ratio shows that 10 people would most likely pay with cash in a group of 40 customers. Therefore, the statement is accurate.
c.) The third statement is true. Let's set up a ratio to solve this problem.
People who payed using a credit card : Customers
24 : 80
To put this information in decimal form, divide 24 by 80.
24/80 = .3
Therefore, .3 customers would probably pay using a credit credit card.
d.) The more participants in a survey, the more accurate the results. Therefore, this statement is false because it states the exact opposite of the truth.
