423 is divisible by the prime number two!
423 divided by 2 is 216
432 is also divisible by three!!
432 divided by three is 141
The number 432 is divisible by 2 and 3 both as its unit digit is even and the sum of the digits is 9.
What is the divisibility rule?By the divisibility rule, we can determine whether numbers are divisible by some other numbers or not without dividing.
We know a number is divisible by 2 if its unit digit is even and a number is divisible by 3 if the sum of the digits is divisible by 3.
Given number is 432 unit digits even, therefore, it is divisible by 2,
and the sum of the digits is 9 so it is also divisible by 3.

A group of tourists is determining the order in which to visit national landmarks in Washington, DC. The group contains 200 people. Of those people, 150 are adults, and 50 are children. A random sample of tourists in the group is chosen. Surveying the random sample produced a representative sample of the population. Which was most likely true of the representative sample?
Answer: the representative sample contained more adults than children
Step-by-step explanation:
The options are:
a. The representative sample contained all 200 tourists.
b. The representative sample contained more adults than children.
c. The representative sample contained more children than adults.
d. The representative sample contained an equal number of adults and children.
Number of adults = 150
Number of children = 50
Total = 150 + 50 = 200
Probability of choosing an adult = 150/200 = 0.75
Probability of choosing a child = 50/200 = 0.25
The above shows that the representative sample contained more adults than children. This can be seen in the explanation above as number of adults is thrice that of children.

The area of a door is 3024 square inches. If the length of the door is 48 inches longer than the width of the door, what is the width of the door?
Answer:
The width of the door is 36 inches
Step-by-step explanation:
The given parameters are;
The given area of the door = 3024 in.²
The length of the door = 48 + The width of the door
Let W represent the width of the door
Therefore, we have;
The length of the door = 48 + W
The area of the door = The length of the door × The width of the door
∴ By substitution, the area of the door = 3024 = W × (48 + W)
3024 = W × (48 + W) = 48·W + W²
48·W + W² = 3024
∴ 48·W + W² - 3024 = 0
Rearranging, we get;
W² + 48·W - 3024 = 0
By trial and error, we have;
(W + 84)×(W - 36) = 0
Therefore, given that the width of the door is a natural number, we have;
The width of the door, W = 36 inches
