y intercept : (0,6)
Explanation:
Use the formula:
. y = mx + b
Find m (the slope), using 2 random points of the graph: (-2,0) and (1,9)
. m = (y-y1) / (x-x1)
m = (0-9) / (-2-1)
m = -9 / -3
m = 3
Replace m in the equation:
. y = 3x + b
Find b by replacing y and x by a random point of the graph: (1,9)
. 9 = 3*1 + b
b = 9 - 3
b = 6
Replace b in the equation:
. y = 3x +6
To find the y-intercept replace x by 0 in the equation:
. y = 3*0 +6
y = 0+6
y = 6
=> y-intercept : (0,6)

Step-by-step explanation:
Hello!
The variable of interest is:
X: number of people that voted for Gloria Chavez for mayor.
You need to calculate sample size in order to estimate the population proportion of people that voted for Gloria Chavez for mayor using a 95% confidence level, an estimated proportion of 0.5 and a margin error no greater than 0.03.
The general structure of the CI for the population proportion is "point estimator" ± "margin of error"
The formula for the interval is
p' ±
Where d= is the margin of error of the interval.
Now you have to clear the sample size, n, from the formula.
d=
To estimate the proportion of people that voted for Gloria Chavez you need to take a sample of n= 1073 voters.
I hope it helps!
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400
X=120
