Answer:
The probability of selecting two Independents is 
.
Step-by-step explanation:
From the given information it is clear that:
Democrats = 8
Republicans = 5
Independents = 5
Total number of member in the group is
We need to find the probability of selecting two Independents.
According to binomial distribution the total number of ways to select r items form n items is
Total number of ways to select 2 members from 18 members is
Total number of ways to select 2 members from 5 Independents is
The probability of selecting two Independents is
Therefore the probability of selecting two Independents is .
<span>5x+9=17x-4x+81
-------------------------
Simplify and combine like terms
</span>5x+9=<span>17x+-4x+<span>81
</span></span>5x+9=<span><span>(<span>17x+-4x</span>)</span>+<span>(81<span>)
</span></span></span>5x+9=<span>13x+<span>81
</span></span><span>-----------------------------------
Subtract 13x from each side
</span><span><span>5x+9-</span>13x</span>=<span><span>13x+81-</span><span>13x
</span></span>-8x+9=<span>81
</span><span>-------------------------------------------
Subtract 9 from each side
</span><span><span>-8x+9-</span>9</span>=<span>81-9</span>
<span><span>-8x</span></span>=<span>72
</span><span>------------------------------------------------
And now divide each side by -8
-8x </span>÷ -8 = 72 ÷ -8
<span>x = -9

F(g(x))=7g(x)+4
f(g(-3)=7 V(-3+4) + 4= 7*1+4=7+4=11
the answer is 11
Answer:
Perimeter: 88m
Step-by-step explanation:
Area of the square plot = (Side) X (Side)
And we are given the area is 484m²,
therefore, (Side) X (Side) = 484m²
or,
(Side)² = 484, taking square root on both the sides,
= 
Side = 22m.
And we know that, perimeter of a square is = 4 X (Side)
Therefore, Perimeter = 4 X 22 = 88m

Answer:
30cm^2
Step-by-step explanation:
area of large rectangle = length x width
= 5 X 9 = 45 cm^2
area of small rectangle = length x width
= 3 X 5 = 15 cm ^2
45 - 15 = 30cm^2
