(1) C = 15x + 40000 ...............because it cost $15 to produce each CD with a one-time cost of $40,000
(2) R = 59x ......................because each CD will sell for $59
(3) P = R - C → P = 59x - (15x + 40000) → P = 44x - 40000
(4) 44x = 40000 → x = 909 ........ They must sell 909 in order to break even
207/9 = 23
23 people per class.
23 * 6 = 138.
In 6 classes, there are 138 students.
Answer:

Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as

Answer:
P [ X ≤ 9.8 ] = 0.1335
Step-by-step explanation:
P [ X ≤ 9.8 ] = [ ( 9.8 - 10.2 )/1.8√25 ]
P [ X ≤ 9.8 ] = - 0.4*5/1.8
P [ X ≤ 9.8 ] = - 2 / 1.8
P [ X ≤ 9.8 ] = - 1.11
From z- table we get: α = 0.1335
P [ X ≤ 9.8 ] = 0.1335 or P [ X ≤ 9.8 ] = 0.1335
