Answer:
D
Step-by-step explanation:
Given
f(x) = 
Substitute x- coordinate of point into f(x) and if the value obtained is equal to the y- coordinate of the point then it lies on the graph.
A
(0, 0 )
f(0) =
= 1 ≠ 0 ← not on graph
B
(0, 6 )
f(0) =
= 1 ≠ 6 ← not on graph
C
(6, 1 )
f(6) =
≠ 1 ← not on graph
D
(1, 6 )
f(1) =
= 6 ← lies on graph
Answer:
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
Step-by-step explanation:
The interpretation of a x% confidence interval of proportions being between a and b is that:
We are x% sure that the true proportion of the population is between a and b.
If the 95% confidence interval estimating the proportion of students supporting the fee increase is (0.75; 0.85), what conclusion can be drawn
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
a. If c is the total number of cars washed and p is the profit
The profit depends on the total number of cars washed.
So profit P is the dependent variable and C is the independent variable
(b) yes, the relationship between c and p a function
Because for each input for c, there will be an unique output for P
(c) C is the number of cars
Each car charged is $5
So C cars charged is 5C
The liquid soap costs $34 and is enough to wash 40 cars. So we subtract 34
Hence Profit P = 5c - 34
The equation is P = 5c - 34
(d) The liquid soap costs $34 and is enough to wash 40 cars
So number of cars is 0 to 40
0<=c <=40
soap costs $34
so profit is above 34
When cars = 40 then profit is 5(40) - 34= 166
So profit lies between 34 and 166
34<= P<= 166
Answer:
f(x)=(x-9/2)²-25/4
Step-by-step explanation:
f(x)=x²-9x+14
f(x)=x²-9x+(-9/2)²-(-9/2)²+14
f(x)=(x-9/2)²-81/4+14
f(x)=(x-9/2)²+(-81+56)/4
f(x)=(x-9/2)²-25/4
