Answer:
831.1 million
Step-by-step explanation:
If the exponential model describes the population after 2003 and we must determine the population of the country in 2003 then t=0 because the time only starts after 2003:
e to the power of 0 is equal to 1:
The population in 2003 is 831.1 million
ANSWER
Option D
EXPLANATION
The parent radical function is
The transformed function is
This is a transformation of the form.
which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.
In this case a=2 and k=3,
there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.
The last choice is correct.
Answer:
Mean = 30.9
Range = 80
Interquartile Range = 36
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms. In other words that means 2, 22, 4, 36, 82, 44, 65, 30, 8, 16 go over a fraction like this. There are 10 numbers here so this is our denominator.
For the range, all we do is subtract the minimum value from the maximum which is 82 - 2. That gives us 80.
For the IQ Range....
Arrange the terms in ascending order.
2, 4, 8, 16, 22, 30, 36, 44, 65, 82
Then we need to find the median which is the average of the two middle terms.
So for the lower half of data 2, 4, 8, 16, 22 we have the median of 8
And for the upper half 30, 36, 44, 65, 82 we have the median of 44.
To find the IQ Range it is the difference between the first quartile (8) and the third (44)
So 44 - 8 = 36
