Answer:
Step-by-step explanation:
is g(x) equal to 2x²-1, or 2x²+1 ?
f(x) = x²-3
g(x) = 2x²-1
g(f(x)) = g(x²-3) = 2(x²-3)²-1 =2(x⁴-6x²+9)-1 =
2x⁴-12x²+17
<h3><u>
The value of the number is equal to 16.</u></h3>
7x + 8 = 120
<em><u>Subtract 8 from both sides.</u></em>
7x = 112
<em><u>Divide both sides by 7.</u></em>
x = 16

Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
