Here t is constant only x and y are variables so it reduces to
dy/ty-y^2 = 1/t^2(dx)
just solve it taking t as constant.
hope this helps
Answer:
¼
Step-by-step explanation:
The probability of having a boy is ½ and that of a girl is ½.
Probability of boy, boy is (pb*pb) and given pb to be ½ then we can prove the point as follows
For these two children
The options are as follows
1 boy(first) and 1 girl
2 boys
2 girls
1 girl( first) and 1 boy
These are four possible options and the option for two boys is 1 out of the four.
The probability of 2 boys is ½*½=¼
Answer:
Option (C)
Step-by-step explanation:
In this question we will use the property " similarity of the triangles".
If DE and AC are parallel two triangles BED and BCA will be similar, corresponding sides of the triangles will be proportional.
Option (A).
But
Therefore, given triangles are not similar.
AC and DE are not parallel.
Option (B).
But
Therefore, AC and DE are not parallel.
Option (C).
2.5 = 2.5
Therefore, AC║DE.
Option (D).
But
Therefore, AC and DE are not parallel.
Option (C) will be the answer.
