Just measure the triangles
The constant of variation is usually given using the letter k.
To find K you would divide Y by x, so the equation becomes k = Y/x.
First find k using the first y and x values provided:
k = 10/5 = 2
Now you know k, you can solve for y when x = 2:
using the equation k =y/x, replace k and x with the known values and solve for y:
2 = y/2
y = 2*2
y = 4
Answer:
1/3.
Step-by-step explanation:
P(event a occurs) = 3/9 = 1/3
P(event b occurs) = 3/9 = 1/3
P(a) ∩ P(b) = 1/3 * 1/3 = 1/9
P(b|a) = P(a) ∩ P(b) / P(a)
= 1/9 / 1/3
= 1/3.
701-523=178
Not sure if that's what you're asking but
