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:
a ) the graph for a) is attached
y= -2x+5
when x=0, y=5 and when y=0, x=2.5
b) 4x-3y+9=0
-3y= -9-4x
y= 4/3 x+3
These are both independent events because 1 spin does not effect the other.
P(1st spin is 3) = 1/8
P(2nd spin is 7) = 1/8
P(both) = 1/8 * 1/8 = 1/64
Answer:
43.6 (approximately)
Step-by-step explanation:
Diagonal measures of the screen is,
√(35²+26²)
= √(1901)
= 43.6 (approximately)
