What is the probability that a number selected at random from the set {2, 3, 7, 12, 15, 22, 72, 108} will be divisible by both 2 and 3 ?F. 1/4
G. 3/8
H. 3/5
J. 5/8
K. 7/8

Answers

Answer 1
Answer: Total amount of numbers in the set = 8 .

Total amount that are divisible by both 2 and 3 = 3 .

So the probability of picking one of them is 3/8 = 37.5 percent.
Answer 2
Answer: |\Omega|=8\n |A|=3\n P(A)=(|A|)/(|\Omega|)\n P(A)=(3)/(8)

What is 0+50 x 1-60-60 x 0+10?

Answers

I THINK IT'S
                                                                                           0+50*1-60-60*0+10= 0
0+50=50x1-60-60=-119x0+10=10 so  (50)x(-119)x(10)=-59,900 but if those arent seperated and in order the answer would be 10 because everything times 0 plus 10

The product of 4 and the difference of 7 and 5

Answers

The *PRODUCT* of 4 means you are going to be either multiplying by 4 or multiplying 4 by something. So we have now 4*x. Lets get X. The differene between 7 and 5. You subtract. So then you have
4*7-5 =23 So your answer would be 23.

*WILL GIVE BRAINLIEST* Simplify (5.29 x 10^9) divided by (9.32 x 10^-7). Write in Scientific Notation.

Answers

5.6759656652361 × 10^15

Answer: Using the corrected exponents on the reposted question:. D is the choice.

5.676×10-³

Step-by-step explanation:

5.29÷9.32=0.567596 That would be equivalent to 5.676×10-¹, like 1/0 of 5.676.

Then to calculate 10 ^-9 divided by 10^-7, we subtract the -7 from -9. -9 -(-7) = -2

That leaves us with 10-² × 10-¹ so adding the exponents we have 10-³ to multiply by 5.676 for the scientific notation.

Determine the slope and y-intercept of each linear equation:1) y= -2x +4

2) 5x +7y = 1

Answers

1) y = -2x + 4

          slope: -2 (coefficent.)
           y-intercept: 4 (constant)


2) 5x + 7y = 1
    -5x         -5x

7y = -5x + 1
/7          /7

y = -5/7x + 1/7

          Slope: -5/7 (coefficent.)
          y-intercept: 1/7 (constant)

the vertex of the parabola below is the point (-3,-5). Which of these equations below could be one for this parabola?

Answers

The answer is choice (B).

A standard quadratic written in vertex form is:

y = (x - h)^2 + k, where h and k are the x and y coordinates of the vertex.

So, if h is negative (in this case, -3), then it becomes x + 3.

If k is negative, though, (in this case, -5) then it becomes (x + 3)^2 - 5.

Therefore, the answer is (B).

Answer:

B
