Answer:

A. 0.3204    B. $14.669

Explanation:

Mean = 8.9      SD = 4.5

Required probability = P (X >/= 550/50)

P(X>/=11) = 1 - P[(X - mean/SD) < (11 - mean)/SD]

              = 1 - P(Z < (11-8.9)/4.5)

P(X>/=11) = 1 - P(Z < 0.4666667)

Using Excel NORMDIST(0.4666667,0,1,1)

P(X>/=11) = 1 - 0.6796 = 0.3204

The probability that she will earn at least $550 = 0.3204

b. P ( X  >  x )  =  0.10

1  −  P ( X  −  mean)/SD  ≤  (x  −  mean) /SD = 0.10

P ( Z  ≤  z )  =  0.90

Where,

z  =  (x  −  mean )/SD

Excel function for the value of z:

=NORMSINV(0.9)

=1.282

Hence (x - mean)/SD = 1.282

= (x - 8.9)/4.5 = 1.282

x = (1.282*4.5) + 8.9

x = 14.669

He earns $14.669 on the best 10% of such weekends.

Which of the following scenarios illustrates the law of demand?
Genrish500 [490]

Answer:

Option B is correct.

Explanation:

In order to answer this question correctly, we first need to understand the law of demands.

Law of demands: It says that the relationship of price and quantity demanded is inversely proportional. It means if the price of a particular product goes high, then the quantity of demand will be reduced. Similarly, if the price of the product is low then the quantity of demanded will be higher.

Here,

Option B is the most relevant to the Law of Demand which says that Kathleen eats more steak when the price is low. It means when the price is low, the quantity of steak demanded is higher in Kathleen's case. Furthermore, Kathleen eats less when the price is high. It means, when the price of steak is higher then the quantity of steak demanded from Kathleen is low.

Hence, Option B is the correct option which fulfills the law of demand.
