There are 30 tickets numbered as 1, 2, 3, 4, 30 respectively. One random. What is the probability that the number on the ticket
Anna007 [38]

Answer:

  • 2/3 or 66.66%

Step-by-step explanation:

Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.

We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and  therefore counted twice.

<u>So we subtract 5 to get:</u>

  • 15 + 10 - 5 = 20 numbers

<u>If we chose one ticket at random the probability is:</u>

  • P(2x or 3x) = 20/30 = 2/3 or 66.66%

Answer: 15 + 53/77


Step-by-step explanation:


Multiplying a fraction by 1 does not change the value.

Any number divided by itself is 1.

For instance, 11/11 = 7/7 = 1.


12 + 1/7 + 3 + 6/11 = 15 + 1/7 + 6/11

= 15 + (11×1)/(11×7) + (7×6)/(7×11)

= 15 + 11/77 + (6×7)/77

= 15 + (11 + 6×7)/77

= 15 + 53/77


It is faster to make sure to multiply by the "smallest" form of one that will work, but you don't have to. You only need to make sure that at the end there are no common factors in numerator and denominator, and that numerator is smaller than denominator.

- 4x - 2y = -12 and 4x + 8y = -24<br> Pls help
laiz [17]

Answer:

y=-6 and x=0

Step-by-step explanation:

-4x -2y = -12

4x + 8y = -24

(add the equations)

6y = -36

-36/6 = -6

y=-6

(Add y value in any of the equations)

-4x-2(6) = -12

-4x-12=-12

-4x=0

x=0
