Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3
Answer:
Demand
Step-by-step explanation:
A. Supply is how much the manufacturer produces
C. Equilibrium, in this case, is what the manufacturers try to maintain, not making too much or too little product.
Answer:
7
Step-by-step explanation:
Since the median is equal to the sum of the two bases divided by two
, we have: QR=(5x-14+17)/2; but QR= x+12, so x+12=(5x+3)/2; 2(x+12)=5x+3; 2x+24=5x+3; ordering 5x+3=2x+24; 5x-2x=24-3; 3x=21 so x=21/3 = 7
Answer:
y = 6x + 7
Step-by-step explanation:
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - (-5)) / (-1 - (-2))
= 6 / 1
= 6
Find y-intercept using m from above and anyone of the given points, let's use (-2, -5):
y = mx + b
-5 = 6(-2) + b
-5 = -12 + b
b = 7
Now use m and b from above to make equation of line:
y = mx + b
y = 6x + 7
