Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change = 
= 
= - 4 → C
C
In order to calculate the new vertices, we simply add 1 to the value of x in each point since the translation is towards the positive x-axis and subtract 3 from the y values of each point since the translation is towards the negative y-axis.
A- price of adult's ticket
c- price of children's ticket
a+3c=20
a=c+2
c=a-2
a+3(a-2)=20
a+3a-6=20
4a=26
a=6.5
The cost of an adult's ticket is $6.50
the answer is 10. if you take the lcm of 5 and 2 you should get it.
Answer:
To test whether or not the population regression function is linear rather than a polynomial of order r, use the test of (minus1) restrictions using the F Minus Statistic.
Therefore, option D is the correct answer choice.
Step-by-step explanation:
The test of (r-1) restrictions using the F statistic is the most effective way to test whether or not the population regression function is linear rather than a polynomial of order r.
Therefore, 'use the test of (minus1) restrictions using the F Minus Statistic', option D is the correct answer choice.
