Probability that second is black
This selection can be represented as:
(Black and Black) or (White and Black)
The probability of Black and Black is:
<em>1 is subtracted from the second fraction because it is probability without replacement</em>
The probability of White and Black is:
<em />
<em>1 is subtracted from the second fraction because it is probability without replacement</em>
So, the required probability is:
Midpoint formula : (x1 + x2) / 2, (y1 + y1) / 2
(4,1)....x1 = 4 and y1 = 1
(x,y)....x2 = x and y2 = y
sub
(4 + x) / 2 , (1 + y) / 2 = 3/4
(4 + x) / 2 = 3
4 + x = 3 * 2
4 + x = 6
x = 6 - 4
x = 2
(1 + y) / 2 = 4
1 + y = 4 * 2
1 + y = 8
y = 8 - 1
y = 7
ur other endpoint, R, is (2,7)
Answer: 10 inches
Step-by-step explanation:
If the two triangles are similar, that means their sides are proportional to each other.
- JK = 15
- JL = 15 + 6 = 21
- JM = 14
<em>The proportion would look like this:</em>
<em />
<em>Substitute in the values:</em>
<em />
<em>Cross-multiply and solve for JN:</em>
<em />
