Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire song album = y dollars
Person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
Person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second we get
x = 0.99 dollars
Putting the value of x in the first equation we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
Answer:
Step-by-step explanation:
It would be more obvious if it says z is a standard Normal variable and that the question is related to statistics.
From "Computing Probabilities Using the Cumulative Table" , the probability of z is less than 1.16, P(z<1.16) = 0.8770.

<span>In the figure, all the dimensions of the cuboid
a = 4/5m side of the base
b = 1/3m second side of the base
c = h = 1/4m height solid
The volume is the product of the edge
V = abc = 4/5m * 1/3m * 1/4m = 4/60m</span>³ = 1/15m³
Answer B
