Answer:

1/3.

Step-by-step explanation:

Prob(Drawing white marble) = 2/3

Prob(Drawing a black marble on second draw ) =  1/2

So:

Prob(Drawing a white then a red marble) = 2/3 * 1/2

= 2/6

= 1/3.

Gnesinka [82]

Answer:

7/9

Step-by-step explanation:

5 5/6 equals 35/6. 7 1/2 is equal to 15/2.

Then you do 35/6 times 2/15. You flip the 15/2 to get 2/15.

35/6 times 2/15 is 70/90 which equals 7/9.

Hope this helps :)

2. A line passes through points (-1,-2) and (1,4). What is the equation of the line? TI​
Simora [160]
Slope = "rise over run" the difference in y values divided by the difference in x values
= 6/-3 = -2 = m. It's negative because as x increases, y decreases

plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)

y+2 = -2(x-2)

simply if you want

Y = -2x +4 -2 = -2x +2

or

2x +y = 2
