Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200
Answer:
V =64 ft^3
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
V = 4^3
V =64 ft^3
Answer:
The correct answers are A, D, and E.
Step-by-step explanation:
The expected probability of the spinner landing on an even number is 50%, or 125 times. However, it lands on an even number 135 times, which is equal to 54%. This is more than expected. The actual probability is the probability after an experiment has been conducted, therefore the actual probability of landing on an odd number is 46%. The expected probability is the probability before an experiment is conducted, so it is 50%. It is equally likely for the spinner to land on an even or odd number, because each spin is an independent event.
I hope this helps!
