you are the sales manager for solar panel company. you receive a commission based on the total sales of all the salespeople you
kondaur [170]

Answer:

The total commission is $8905

Step-by-step explanation:

The commission on first $80000 = 2%

The commission on next $80000 = 4%

The commission on the sales of more than $160000 = 5%

Now we have to calculate the total commission on the amount of $242100. Let divide the amount in three parts, $80000 + $80000 + $82100 = 242100

Now total commission = $80000×2% + $80000 ×4% + $82100×5%

Total commission = $8905

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1300 hours
matrenka [14]

Answer:

0.03593

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 17,340

μ is the population mean = 15,000

σ is the population standard deviation = 1300

z score:

z = 17340 - 15000/1300

z =1.8

Probability value from Z-Table:

P(x<17340) = 0.96407

P(x >17340) = 1 - P(x<17340)

= 1 - 0.96407

= 0.03593

The probability that the life span of the monitor will be more than 17,340 hours is 0.03593
