A number is chosen at random from 1 to 10.Find the probability of not selecting a multiple of 3.

Answers

Answer 1

Answer: the probability is 9/10 or 90%

Answer 2

Answer: First, you need to figure out how many of the numbers are multiples of 3. The numbers 3, 6, and 9 are all multiples of three, so three numbers are thrown out of the probability.

There are now 7 numbers left. Your probability is out of ten, so there is a 7/10 of a chance to not pull a number that is a multiple of 3.

An equation and the steps to solve it are shown below:2x − one over four (12x + 4) = 3

Step 1: 2x + 3x + 1 = 3
Step 2: 5x + 1 = 3
Step 3: 5x + 1 − 1 = 3 − 1
Step 4: 5x = 2

In which step was the error made and why?

Step 1, because incorrect signs have been used
Step 2, because the terms have been added incorrectly
Step 3, because a number has been subtracted from both sides of the equation
No error was made

Answers

step 1,
what i am thinking you're saying is 2x-1/4(12x+4)
so you would distribute the -1/4 to the 12x and the 4.
therefore making it a negative, not a positive.
so, i think step 1 is wrong.

Choose the polygon that is a regular quadrilateral

Answers

"Regular quadrilateral" means it has four sides, and the
sides AND the inside angles are all equal.

-- The one at the upper left is a rhombus. All 4 of its sides
are the same length, and the first time I saw it, I picked it.
But then I remembered that in order to be 'regular', the
inside angles also have to be equal, and in a rhombus,
they're not.

-- The one in the lower right is a square. It has four sides,
they're all equal, and the inside angles are all the same too.
So the square is the only one that does the job for you.
