Elodia [21]
Given:
3n + 5

n = 1 ; 3(1) + 5 = 3 + 5 = 8
n = 2 ; 3(2) + 5 = 6 + 5 = 11
n = 3 ; 3(3) + 5 = 9 + 5 = 14
n = 4 ; 3(4) + 5 = 12 + 5 = 17

The first four terms of the sequence are: 8, 11, 14, 17.  Second option.

A driver education course
Kobotan [32]

Answer:

  1. after 4.5 months (or 5)
  2. $795

Step-by-step explanation:

10% of $100 per month is $10 per month.

1. By saving $10 per month on insurance cost, Dan's savings after 4.5 months will be equal to the $45 cost of his course. (If billing is monthly, he won't experience any net gain from the course until the 5th insurance payment--after 5 months.)

__

2. In 7 years, the savings on insurance costs will total ...

  (7 years)×(12 months/year)×($10 /month) = $840

His cost for the course is $45, so his net saving is ...

  $840 -45 = $795 . . . net saving by age 25

The ages (in years) and weights (in pounds) of all wide receivers for a football team are listed. Find the coefficient of variat
IceJOKER [234]

Answer:

The coefficient of variation for the weight and age are 5.9% and 10.6%.

Step-by-step explanation:

The coefficient of variation (CV) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.

The formula to compute the coefficient of variation is:

CV=\frac{\sigma}{\mu}\times 100\%

Here σ = standard deviation and µ = mean.

Compute the mean and standard deviations of the two data set in Excel using the following functions.

Mean=AVERAGE()

Standard deviation=STDEV.S()

Consider the Excel sheet attached.

The mean and standard deviation of weight are:

Mean = 202, Standard deviation = 11.87

And the mean and standard deviation of weight are:

Mean = 25.88, Standard deviation = 2.75

Compute the coefficient of variation for the weight as follows:

CV_{weight}=\frac{\sigma}{\mu}\times 100\%

              =\frac{11.87}{202}\times 100\%\\\\=5.87624\\\\=5.9\%

Compute the coefficient of variation for the age as follows:

CV_{age}=\frac{\sigma}{\mu}\times 100\%

              =\frac{2.75}{25.88}\times 100\%\\\\=10.62597\\\\=10.6\%

Thus, the coefficient of variation for the weight and age are 5.9% and 10.6%.
