8(2x – 14)+13 = 4x – 27We first multiply what we can.
16x-112+13=4x-27
Then we sum
16x-99=4x-27
Then we move all the number and separated from x
16x-4x=-27+99
we simplify
12x=72
Then we divide
x=72/12
x= 6
To solve this we put 6 instend of x
8(2(6) – 14) +13 = 4(6) – 27<span>we</span> <span>aolve</span> <span>teh</span> things in parenthesis
8(12-14)+13=24-27
8(-2)+13= 24-27
We <span>just solve</span>
-16+13= -3
-3=-3
So our answer is 6 since -3 does equal to -3
the answer is three digits because the answer is 157.136
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
