Answer:
(b)$29.62
(c)$5.73
Step-by-step explanation:
Basic: Standard internet for everyday needs, at $24.95 per month.
Premium: Fast internet speeds for streaming video and downloading music, at $30.95 per month.
Ultra: Super-fast internet speeds for online gaming at $40.95 per month.
Let the number of customers on Ultra=x; therefore:
Number of Premium customers =2x
Number of Basic customers =3x
Total=x+2x+3x=6x

(a)X=Monthly fee paid by a randomly selected customer.
Therefore, the probability distribution of X is given as:

(b)Average Monthly Revenue per customer
Mean,

(c)Standard Deviation


Answer:
The mark-up percentage is 136%
Step-by-step explanation:
59 - 25 = 34
34/25 = 1.36
Answer: the lowest commission is $163.96
Step-by-step explanation:
Let x represent the lowest monthly commission that a salesman earned.
Let y represent the highest monthly commission that a salesman earned.
The lowest monthly commission that a salesman earned was only 1/5 more than 1/4 as high as the highest commission he earned. This means that
x = y/4 + 1/5 - - - - - - - - 1
The highest and lowest commissions when added together equal $819. This means that
x + y = 819
x = 819 - y - - - - - - -2
Substituting equation 2 into 1, it becomes
819 - y = y/4 + 1/5
Multiplying through by 20, it becomes
16380 - 20y = 5y + 4
25y = 16380 - 4 = 16376
y = 16376/25 = 655.04
x = 819 - 655.04 = 163.96
distribute 8 into 2 and -6v which would give you
36 - 48v + 19 = - 61
add like terms which would be 36 and 19
55 - 48v = - 61
then subtract 55 from -61 because they are on opposite side of the equal sign
- 116 = - 48v
