The probability is the number of specific outcomes divided by all possible outcomes....in this case:
8/12=2/3
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
Answer:
w= 6.88-4.96
Step-by-step explanation:
<h2>The answer is D. 54d + 2</h2><h3>Hope it helps!! </h3>
The first term in the series is 336. The second term is obtained by subtracting 4 from the first term; subtract 4 from that to get the third term; and so on. Then the <em>n</em>-th term in the series is
336 - 4 (<em>n</em> - 1)
or
340 - 4<em>n</em>
The last term in this series is 4, so we solve for <em>n</em> :
340 - 4<em>n</em> = 4
336 = 4<em>n</em>
<em>n</em> = 336/4 = 84
The sum of the series is then
Recall that
Then the sum we want is
