Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles

Mathematics
1 answer:
disa [49]3 years ago
7 0

Answer:

7/15

Step-by-step explanation:

<em>No. of green marbles in the bag= 7</em>

<em>No. of blue marbles in the bag= 8</em>

<em>Total no. of marbles in the bag= 7+8=15</em>

As we know that,

Probability( of a random event A)= \frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=\frac{7}{15}

zheka24 [161]

9514 1404 393

Answer:

  (2, 3), (-3, 2), (-2, -3), (3, -2)

Step-by-step explanation:

You can pick any point you like, then rotate it around the origin to the four quadrants (or axes) by the transformation ...

  (x, y) ⇒ (-y, x) . . . . . . . . . 90° rotation CCW

That is a rotation 90° CCW. Of course a rotation CW can do the same thing for you.

__

One possible square is ...

     (2, 3), (-3, 2), (-2, -3), (3, -2)

8x = 7x + 3<br><br> Would I combine the 8x and the 7x at all in this equation?
Kryger [21]
Yes...thats what u want to do. you want to get the x terms on one side and everything else on the other side.

8x = 7x + 3....so we will subtract 7x from both sides
8x - 7x = 7x - 7x + 3....simplify
1x, or just x = 3 (because ur 7x's cancelled each other out)

so ur answer is : x = 3

and u can check ur answer by subbing it back into the original equation.
8x = 7x + 3
8(3) = 7(3) + 3
24 = 21 + 3
24 = 24 (correct)
