A candidate for mayor plans to campaign at 5 shopping malls before the election. In how many different ways can the candidate sc
Svetlanka [38]

Answer:

120 different ways

Step-by-step explanation:

For the first shopping mall being visited, the candidate has 5 options

Then, for the second mall being visited, there is only 4 options, as one mall was already visited.

Following this logic, there is 3 options for the third mall, 2 options for the fourth mall and 1 option for the last mall.

So the total number of ways that the visits can be scheduled is the product of all these options:

5*4*3*2*1 = 120 different ways

PLEASE ANSWER QUICK A manufacturing facility pays its employees an average wage of $4.50 an hour with a standard deviation of 50
evablogger [386]

Answer:

B.77.4%

Step-by-step explanation:

Mean wage (μ) = $4.50

Standard deviation (σ) = $0.50

For nay given salary X, the z-score is given by:

z=\frac{X-\mu}{\sigma}

For X = $3.75, the z-score is:

z=\frac{3.75-4.50}{0.50}\\z=-1.5

For X = $5.00, the z-score is:

z=\frac{5.00-4.50}{0.50}\\z=1

A z-score of -1.5 corresponds to the 6.68th percentile, while a score of 1 corresponds to the 84.13th percentile. Therefore, the percentage of workers getting paid between $3.75 and $5.00 an hour is:

P=84.13-6.68\\P=77.45\%

The answer is alternative B.77.4%
