Probability ( 1 blue marble and 3 green marbles) = ( Blue, green, green, green) + ( green, blue, green, green) + ( green, green, blue, green) + ( green, green, green, blue) = { (8/13) × (5/12) × (4/11) × (3/10) } + { (5/13) × (8/12) × (4/11) × (3/10) } + { (5/13) × (4/12) × (8/11) × (3/10) } + { (5/13) × (4/12) × (3/11) × (8/10) } = (4/143) + (4/143) + (4/143)+ (4/143) = 16/143 If the answer does not correspond to yours, do tell me. I'll try to correct mine

P (1 blue, 3 green) = \frac{C (8, 1)*C(5, 3)}{C(13, 4)} =  \frac{80}{715}= \frac{16}{143} }

Three days last week Maria ran 3/4 mile 7/8 Mile and 3/5 mile list of distances in order from least to greatest
NikAS [45]

I was taught to get a common denominator and then arrange them in the correct order.

So first you find out what all the denominations can be multiplied to. That would be 40

So you multiply the bottom of each fraction by a number that will get 40.

3/4 * 10 = 30/40

7/8 * 5 = 35/40

3/5 * 8 = 24/40

Then you get 30/40, 35/40, and 24/40.

Then you organize the m.

24/40, 30/40, and 35/40

The slope of the line below is -2. Use the coordinates of the labeled point to
nika2105 [10]

Answer:

y + 6 = -2(x - 4)

Step-by-step explanation:

Given:

Slope (m) = -2

Point on the line = (4, -6)

Required:

Point-slope equation of the line

Solution:

Point-slope equation takes the following form:

y - b = m(x - a),

Where,

m = slope of the line = -2

(a, b) = coordinates of the point on the line. = (4, -6)

Plug in the values into the slope-point equation

y - (-6) = -2(x - 4)

y + 6 = -2(x - 4)
