20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Original price would be $675
$20 multiply 15 to get $300 being taken off.
add 300 to 375 you get $675
FRACTIONAL FORMAT:
700/200
= 600/200 + 100/200
= 3 + 1/2
= 7/2
DECIMAL FORMAT:
3 + 1/2
= 3.0 + 0.5
= 3.5
Common difference between the terms is 36
Formula for nth term is
27th term is 961
Given :
X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence
To Find:
We need to find the constant difference between the given terms and also find the nth term . Also find the 27th term .
To find the difference , we need to take the difference of consecutive terms
Both the common differences are equal
First term is 25
second term is 2(25)+11=61
Difference is 61-25=26
Common difference = 36
Use nth term formula is
To find 27th term , replace n with 27
