A bag contains 10 marbles: 3 are green, 2 are red, and 5 are blue. Jose chooses a marble at random, and without putting it back,
Ludmilka [50]
We know that
g=3
r=2
b=5
total marbies=g+r+b------> 3+2+5----> 10

a) <span>probability that the first marble is red
P(red)=r/total marbies------------> 2/10-----> 1/5

b) </span><span>probability that the second marble is blue
in this case total marbles-------> 9
P(blue)=b/total marbles----------> 5/9

c) </span><span>the probability that the first marble is red and the second is blue
(1/5)*(5/9)=1/9

the answer is
1/9</span>

Find the slope and y-intercept of the line 6x−7y=2
Allisa [31]
To easily find the slope and y intercept of the line, put it in slope intercept form by rearranging the variables around.

6x-7y = 2
6x - 7y + 7y = 2 + 7y
6x = 7y + 2
6x - 2 = 7y + 2 - 2
7y = 6x - 2
7y/7 = 6x/7 - 2/7
Y = 6/7(X) - 2/7

Y = 6/7x - 2/7
Slope = m = 6/7
Y intercept = b = -2/7
(0, -2/7).

Easy! Just multiply 7 1/3 by 8 which leaves you with 58 2/3. Now, that 1/4 is 1/4 of an hour. If you can fill 7 1/3 boxes in 1 hour, how many can you fill in 1/4? 7 1/3 divided by 1/4 is 29 1/3. Add them together. 81 boxes.

Which equation reprints the slope intercept form of the line below ? Y- intercept = (0,2) slope = -3/7
Ann [662]

Answer:

y = -\frac{3}{7} x + 2

Step-by-step explanation:

The y-intercept of the line is (0,2)

The slope of the line is  -\frac{3}{7}

We derive the slope of a line by dividing the change in y by the change in x

So,

\frac{y - 2}{x - 0} =  -\frac{3}{7}

y - 2 =  -\frac{3}{7} x

The equation of the line therefore is;

y =  -\frac{3}{7} x + 2
