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
Step-by-step explanation:
a)
Two of the three interior angles are known. Both are equal to 55°. This can be seen by looking closely at the picture. To find the third angle subtract the other two from 360°
b)
Do the same thing only afterward subtract the third angle from 180 to find the supplementary angle
To answer this question correctly, first we must find out how much lou
pays for health and disability insurance for a year total, then divide
that number by 12, for each month of the year to find out how much he
pays monthly. The calculation and answer would be the following:
((Health insurance cost * 30%) + (Disability cost * 10%)) / 12 =
(1140+120)/12 = $105 monthly
Let K = km in 7 weeks
Equation:
K = 7(20)
