Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

What is the probability that 4 randomly selected people all have different birthdays? Ignore leap years, and round your final an
Flauer [41]

Answer:

(D)0.9836

Step-by-step explanation:

There are 365 days in a year.

Since each person has a different birthday:

  • We can choose a birthday for the first person 365 out of 365 days.
  • We can choose a birthday for the second person 364 out of 365 days.
  • We can choose a birthday for the third person 363 out of 365 days.
  • We can choose a birthday for the fourth person 362 out of 365 days.

Therefore,

P(4 randomly selected people all have different birthdays)

=\dfrac{365}{365} \times \dfrac{364}{365} \times \dfrac{363}{365} \times \dfrac{362}{365}\\\\=0.9836

x = k/y           Multiply each side by y

k = xy            Insert values

  = 6 × 72

  = 432

x = 432/y     Let y = 36

  = 432/36

x = 12
