ANSWER:
(1) = √112
(2) = 0.1
(3) = 2
(1) GIVEN:
- √7 , √28 , √63...
TO FIND:
- The next term of the above A.P
SOLUTION:
√7 = √7
√28 = 2√7
√63 = 3√7
√7 , 2√7 , 3√7 ...
Here ,. a = √7. d= 2√7-√7 = √7
Formula:
=> nth term = a+(n-1)d
=> 4th term = √7 + (4-1)√7
=> 4th term = 4√7
So next term of A.P = 4√7 Or √112
(2) GIVEN:
- Probability of winning race = 9/10
TO FIND:
- Probability of not winning race
SOLUTION:
Formula
P( Event) + P( not Event ) = 1
So probability of not winning race = 1 - 9/10
= 1/10
= 0.1
- Probability of not winning race = 0.1
(3) GIVEN:
- DE || AC
TO FIND:
- The value of 'x'
SOLUTION:
Putting the values we get;
=> 3/4 = 1.5/x
=> 3x = 1.5 *4 ( by cross multiplication)
=> x = 2
So value of x = 2
