First find the slope of f(x).
m=(y2-y1)/(x2-x1)
m=(1-5)/(2-0)
m=-4/2
m=-2
y=-2x+b, using (2,1) we can solve for the y-intercept, "b"
1=-2(2)+b
1=-4+b
5=b
y=-2x+5
So f(x) has a y-intercept of 5
g(x)=6m+3
So g(x) has a y-intercept of 3
h(x)=3x+4
So h(x) has a y-intercept of 4
Then g(x) has the lowest y-intercept of just 3.
Your answer will be 7.50. What I did was take 1.25 and times it by 6.
Answer:
Step-by-step explanation:
Information given
n=564 represent the sample selected
X=51 represent the number of people who rated the overall services as poor
estimated proportion of people who rated the overall services as poor
is the value to compare
z would represent the statistic
Hypothsis to analyze
We want to analyze if the proportion of customers who would rate the overall car rental services as poor is 0.1, so then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic for a one z test for a proportion is given by:
(1)
Replacing the info given we got:
And the p value since we have a bilateral test is given b:
Each year + $25. 4 years = $100. 100+1000= $1100

Hope you could get an idea from here.
