Step-by-step explanation:
again, we're assuming that both triangles are similar, and thus using proportions.

we do not use the -10, because whatever value "x" may be, can't be negative or even 0.
Answer:
The common difference of the given AP is d=5.
Step-by-step explanation:
Given the sequence

An Arithmetic sequence has a constant difference 'd' and is defined by

Computing the common difference of all the adjacent terms


As the difference between all the adjacent terms is the same and equal to

Therefore, the common difference of the given AP is d=5.
S=Sample Space
n(S)=no. of total outcomes of sample space
= 50%×10=5
n(E)=no. of favourable events=3
Probability of giving birth to boy is,
P(B)=n(E)/n(S)
=3/5....Ans
