Well first add up all the numbers of marbles (which is 34 in total) and divide it by the number of black marbles.
(which should give you 8/34)
Then simplify the fraction and you should get 4/17

8+14+12= 34
chance of picking a black marble is 8/34 because there are 8 black marbles and 34 marbles in all. the answer reduced is 4/17 because 8/34 ÷2 ( both numerator and denominator are divisible by this number)

4/17

What is the slope of the line whose equation is y−4= StartFraction 5 Over 2 EndFraction.(x−2)?
Yuki888 [10]

For this case we must find the slope of the following equation:

y-4 = \frac {5} {2} (x-2)

By definition, the point-slope equation of a line is given by:

y-y_ {0} = m (x-x_ {0})

Where:

(x_ {0}, y_ {0}): It is a point through which the line passes

m: It's the slope

So, the slope of the given equation is:

m = \frac {5} {2}

Answer:

Option D
