Answer:
Step-by-step explanation:
If you treat (x+5) as a single value and (x-2) as the values of x and +2, you can distribute (x+5) to x and +2: ( (x-5)*x + (x-5)*2 ). Then you can treat x-5 as the values of x and -5 and distribute those to the numbers next to them: (×^2 - 5x) + (2x - 10). This results in x^2 -3x - 10.

-np-70 < 40
Add 70 to both sides,
-np < 110
divide -p to both sides,

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
