Answer:
28/171
Step-by-step explanation:
The probability initially of drawing a red would be 8/19 since there were 19 marbles in the bag in the beginning. However, without replacement, the probability of drawing another red would be 7/18 as there would be one less red and one less marble in the bag so to find the combined probability of getting 2 red marbles, multiply 8/19 by 7/18 to get: 56/342 = 28/171
Answer:
x = 10
IJ = 32
Step-by-step explanation:
Since J is between I and M, JM and IJ combined gives you IM.
JM + IJ = IM
18 + 3x + 2 = 5x
20 + 3x = 5x
20 + 3x - 3x = 5x - 3x
20 = 2x
20/2 = 2x/2
10 = x
Now that you have x, you can find IJ
IJ = 3x + 2
IJ = 3(10) + 2
IJ = 30 + 2
IJ = 32
You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
I kinda know how to answer this but are there any answer choices?
Answer:
M = (Y2 - Y1) / (X2 - X1)
Step-by-step explanation:
First, look at a graph of a line and find two points, 1 and 2. You can use any two points on a line. The slope will be the same between any two points on a straight line.
Note the X and Y value for each of the points.
Now we'll designate the X and Y value for points 1 and 2. We'll use subscripts to identify them in the slope formula.
Hope this helps!
