Answer:
$5,340
Step-by-step explanation:
Given :
Making a probability distribution :
X : ___12000 ____0 _____-6200
P(X) __ 0.6 _____ 0.1 _____ 0.3
Tge expected value of the purchase si equal to the expected value or average, E(X) :
E(X) = ΣX*p(X)
E(X) = (12000 * 0.6) + (0 * 0.1) + (-6200 * 0.3)
E(X) = 7200 + 0 - 1860
E(X) = $5,340
Answer:
-0.625
Step-by-step explanation:
-5/8=-0.625
Step 1: 0.35 = 35⁄100
Step 2: Simplify 35⁄100 = 7⁄20
answer: 7/20
Answer: x = 2y + 4
Step-by-step explanation:
y=1/2x-4
multiply both sides by 2
2y=x-4
substract from both sides 2y
0=x+–2y-4
substract from both sides x
-x=-2y-4
multiply both sides by -1 to get positive x
x=2y+4
No, only multiples of 10 end in a 0
hope this helps :)
