Step-by-step explanation:
Answer:
G. 0.45
Step-by-step explanation:
To find expected value, you simply multiply the value of each outcome (the numbers in the left column) by its probability
(the numbers in the right column) and then add them all together.
0(0.7) + 1(0.2) + 2(0.05) + 3(0.05)
0 + 0.2 + 0.1 + 0.15 = 0.3 + 0.15 = 0.45
Answer: 2(−x+y=−2)
2(−x+y=−2)
1(2x−3y=4)
Becomes:
−2x+2y=−4
2x−3y=4
Add these equations to eliminate x:
−y=0
Then solve−y=0for y:
−y=0
−y/-1 = 0/-1 (Divide both sides by -1)
y=0
Step-by-step explanation:
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+y=−2
Substitute 0 for y in −x+y=−2:
−x+0=−2
−x=−2(Simplify both sides of the equation)
−x/-1 = -2/-2 (Divide both sides by -1)
x=2
Answer:
x=2 and y=0
Answer:
I believe the independent variable is c, or amount of cars washed.
Step-by-step explanation:
You cannot make a profit without washing any cars. P, representing the profit, can only be determined after the amount of cars washed is known.
