How many natural numbers less than 600 are neither multiples of 4 nor multiples of 6?

Mathematics
1 answer:
SashulF [63]3 years ago
3 0

Answer:

400  

Step-by-step explanation:

There are 599 numbers  from 1 to 599.

There are

INT(599/4) = 149 numbers divisible by 4 and

INT(599/6) = 99 numbers divisible by 6,

However, some of these numbers have been counted twice. For example, 12 is counted twice, because 12 is divisible by both 4 and 6. There are

INT(599/12) = 49 numbers divisible by 12.

599 numbers

-149 divisible by 4

- 99 divisible by 6

<u>+49 double-counts </u>

400 numbers not divisible by 4 or 6.

Using the slot method and multiple cases, calculate the probability that you would roll 3 sixes.
kotegsom [21]

Answer:

P = 1/216

the probability that you would roll 3 sixes is 1/216

Step-by-step explanation:

For a given dice, there are six possibilities.

We have;

1,2,3,4,5,6

The probability of rolling a six(6) is;

P(6) = 1/6

Then, the probability of rolling 3 sixes is a multiple of the P(6), given as;

P = P(6) × P(6) × P(6)

P = 1/6 × 1/6 × 1/6

P = 1/216

the probability that you would roll 3 sixes is 1/216

Find the difference of <br> (3c-d)^2
OverLord2011 [107]

Answer:

  • <u>9c² - 6cd + d²</u>

Explanation:

To find the difference (3c - d)² you should recognize that it is the square of a difference of two terms.

The square of the difference of two terms is a special case that you should remember: it is equal to the square of the first, minus twice the product of the first and second, plus the square of the second:

  • (x - y)² = x² - 2xy + y²

For the binomial (3c - d)² you have that:

  • x = 3c
  • y = d

Thus:

  • (3c -d)² = (3c)² - 2(3c)(d) + d² = 9c² -6cd + d² ← answer

17 students on the math team want to raise 483.62 to buy practice books they have already raised 218.25 if each students raises
Dafna11 [192]

483.62 - 218.25 = 265.37

265.37 / 17 = 15.61

Each student should raise 15.61.

Hope this helps.
