Answer:
30th term of the sequence is -19
Step-by-step explanation:
first term = 10
common difference = 9- 10 = -1
so, nth term = a + (n-1) d
( where n is number of term, a = first term ,
d = common difference. )
- 30th term = 10 + (30-1) × -1
- 30th term = 10 - 29
- 30th term = -19

The answer is (2.2) so the other answer should be wrong
Answer:
this is Proportional
Step-by-step explanation:
0-0 there is nothing here
but 1-6 there's something
2-12 is when it become's proportional
1/6 = 2/12
Answer:
0.273
Step-by-step explanation:
Let the number of insured pieces of luggage be <em>i</em> and <em>u</em> be the number of uninsured pieces of luggage, therefore,
<em>i </em>+ <em>u </em> = 27
Now,
probability that exactly one of the damaged pieces of luggage is insured = (iC1)(uC3)/(27C4)
probability that none of the damaged pieces are insured = (uC4)/(27C4)
and,
(iC1)(uC3)/(27C4) = 2 (uC4)/(27C4)
=> <em>u − </em>2<em>i </em>= 3
By solving, <em>i </em>+ <em>u </em> = 27 and <em>u − </em>2<em>i </em>= 3
<em>i</em> = 8 and <em>u</em> = 19
and,
(8C2)(19C2)/(27C4) = 0.273
