Answer:
A. The E(Y) is 0.80
B. The expected amount of the surcharges is $165
Step-by-step explanation:
A. In order to calculate the E(Y), we would have to calculate the following formula:
E(Y)=∑yp(y)
E(Y)=(0*0.5)+(1*0.25)+(2*0.20)+(3*0.05)
E(Y)=0+0.25+0.40+0.15
E(Y)=0.80
B. In order to calculate the expected amount of the surcharges we would have to calculate the following formula:
E($110Y∧2)=110E(Y∧2)
=110∑y∧2p(y)
=110((0∧2*0.5)+(1∧2*0.25)+(2∧2*0.20)+(3∧2*0.05))
110(0+0.25+0.80+0.45)
=$165
Answer:
Step-by-step explanation:
Not sure what the question is here.
L = W-8
Perimeter = 2L + 2W = 44
L+W = 22
(W-8)+ W = 22
W = 15 ft
L = 7 ft

<h3>
Answer:</h3>
600 m
<h3>
Step-by-step explanation:</h3>
The slope between 1 minute and 2 minutes is ...
... (800 -500)/(2 -1) = 300 . . . . . . m/min
Thus in 20 seconds, 1/3 minute, Jason will fall ...
... (1/3 min)·(300 m/min) = 100 m
This distance is in addition to the 500 m he has already fallen in the first minute.
In 1 min 20 sec, Jason falls 500 m + 100 m = 600 m.
_____
<em>Comment on the graph</em>
We don't expect Jason's rate of fall to change dramatically at the 2-minute mark. We suspect the last point should be (2 2/3, 1000).
