Answer:

Finding the mean is very simple, add them all together and divide that sum by the number of data points you have; in this case there are 45

Step-by-step explanation:

\frac{74+67+74.25+64+72+...}{45} = mean

The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance,
babymother [125]

Answer:

The range is: 13. The population mean is: 8.5. The population variance is: 15.85. The population standard deviation is: 3.9812.

Step-by-step explanation:

The range: 15 - 2 = 13

The population mean is:

Mean = ( 2 + 9 + 15 + 5 + 14 + 8 + 11 + 7 + 4 + 10 ) / 10 = 8.5

The population variance ( S² or Sigma² ):

S ² = 1/10 · ( ( 2 - 8.5 )² + ( 9 - 8.5 )² + ( 15 - 8.5 )² + ( 5 - 8.5 )² + ( 14 - 8.5 )² + ( 8 - 8.5 )² + ( 11 - 8.5 )² + ( 7 - 8.5 )² + ( 4 - 8.5 )² + ( 10 - 8.5 )² )

S ² = 15.85

The population standard deviation:

S = √(S²) = √15.85 = 3.9812

I need help setting up and solving this
melisa1 [442]

e is a special number, so you would need to use a calculator to solve this.

a) replace t in the equation with 5 ( 2005 - 2000 = 5 years)

A = 16.6e^0.0457*5 = 20.86 million Round to nearest tenth = 20.9 million.

b) replace A with 23.3 and solve for t:

23.3 = 16.6e^0.0457*t

Divide both sides by 16.6:

1.4036 = e^0.0457t

Take the natural logarithm of both sides:

0.0457t = LN(1.4036)

Divide both sides by 0.457:

t = LN(1.4036)/0.0457

t = 7.419 years, rounded to nearest tenth = 7.4 years.
