there are 15 cards , numbered 1 through 15 , if you pick a card what is the probability that you choose an odd number or a two

2 answers:

7 0

Picking an odd number's probability would be 8/15 because there are 8 odd numbers in the pile of cards.

Picking the number two's probability would be 1/15 because there is 1 card with the number two on it in the pile of cards.

Add them together to get 9/15 and there's your answer.

(P.S. 8/15 is not the answer because two is not an odd number)

Answer:

Step-by-step explanation:

The diagonal gives you a 30°-60°-90° triangle. The lengths of the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.

The side opposite the 60° angle is 12 ft.

The side opposite the 30° angle is 12/√3 ft

The side opposite the 90° angle is 2×12/√3 = 24/√3 = 24√3/3 = 8√3 ft

Select all correct factored forms for the equation x^2+x−42=0 . Answer Choices A .(x−7)(x+6)=0 B. (x+7)(x−6)=0 C. (x−6)(x+7)=0 D

Both B and C will give you the correct factorization for this equation.

When you factor a quadratic, you are looking for factors of the last number (-42) that add up to the middle coefficient (1). Below are the factors of -42.

1*-42

-1*42

2*-21

-2*21

3*-14

-3*14

6*-7

-6*7

And since these two are the only ones that add up to 1, we use these in parenthesis, creating the following (x - 6)(x + 7) - which is answer C. You also can switch the order due to the laws of multiplication. If you switch them around you get (x + 7)(x - 6) - which is answer B as well.

Please help with best explained answer

Answer:

x = 25 B = 65˙ C = 50˙

Step-by-step explanation:

Triangle Sum- All three angles in a triangle add up to 180˙

65 + (3x - 10) + (2x) = 180

65 - 10 +3x + 2x = 180 Combine like terms

55 + 5x = 180 Move the 55 over to combine w/180.

- 55 -55

5x = 125 Divide by 5

5 5

x = 25 Answer

B C

(3x - 10) (2x)

(3*25 - 10) (2* 25)

65˙ 50˙
