Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 2 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - x - 1 ← equation of perpendicular line

Step-by-step explanation:
Answer: D. range
Step-by-step explanation:
To measure the center of the tendency we use Mean , median or mode depends on the type of data.
But when we discuss about the distance between the initial point and the final point in a data , we use 'range' as term for this.
Range= distance between initial and final point.
here, range = distance between the starting point and the point where water-skiing accident occurs.
Hence, the correct option is D. range
Answer:
Step-by-step explanation:
Given : A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform.
sample size : n= 1000
sample proportion:
Critical value for 95% confidence interval =
Confidence interval :
Hence, the 95% confidence interval for the true percent of registered voters in Flagstaff who support immigration reform:
