Papessa [141]3 years ago

Answer:

mean= 5.5

median=5.5

No mode.

range=9

Step-by-step explanation:

Recall that the mean of a data set is the sum of its terms divided by the number of terms.

1+2+3+4+5+6+7+8+9+10=55

55/10=5.5

Recall that the median of a data set is the value at the middle (the median) of the data set. In order to find the median, the data set must be arranged from lowest to highest. Once it is, we cross out one at the end, one at the beginning, one at the end, one at the beginning, and so on until we find the middle value.

Since there are an even number of terms, the median will be between the two middle values. Take the average of the two:

median=5+6 divided by 2=5.5

The mode of a data set is the element that appears most frequently. Since each element in this data set is unique and only appears one time, there is no mode.

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is

10-1=9

Based on a study of population projections for 2000 to​ 2050, the projected population of a group of people​ (in millions) can b
Olegator [25]

Answer:

(a) 0.107 million per year

(b) 0.114 million per year

Step-by-step explanation:

A(t) = 11.19(1.009)^t

(a) The average rate of change between 2000 and 2014 is determined by dividing the difference in the populations in the two years by the number of years. In the year 2000, t=0 and in 2014, t=14. Mathematically,

\text{Rate}=\dfrac{A(2014) - A(2000)}{2014-2000}=\dfrac{11.19(1.009)^14-11.19(1.009)^0} {14}

A(0)=\dfrac{12.69-11.19}{14}=\dfrac{1.5}{14}=0.107

(b) The instantaneous rate of change is determined by finding the differential derivative at that year.

The result of differentiating functions of the firm y=a^x (where a is a constant) is \dfrac{dy}{dx}=a^x\ln a. Let's use in this in finding the derivative of A(t).

A\prime(t) = \dfrac{A}{t}=11.19\cdot1.009^t\ln1.009

In the year 2014, t=14.

A\prime(14) =11.19\cdot1.009^14\ln1.009=0.114
