Step-by-step explanation:
Tricky. Very neat.
You are missing the minor arcAC and you need it, but don't fret. It can be found.
The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )
The minor arc is the supplement of x.
The minor arc is also equal to the the central angle
So the minor arc is 180 - x
x = 1/2 (235 - (180 - x) ) Remove the inside brackets
x = 1/2 (55 + x ) Remove the remaining brackets
x = 1/2 *55 + 1/2x Subtract 1/2x from both sides
1/2 x = 27.5 Multiply both sides by 2
x = 55

Answer:
The slope of the line would be 1
Step-by-step explanation:
To do this, you would take the slope formula, (Y2-Y1)/(X2-X1)
Next we would plug in the points of the line
(13-8)/(8-3)
5/5
1/1
Therefore, the slope of the line is 1.

Answer:
There is 95% confidence that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89).
Step-by-step explanation:
A (1 - <em>α</em>)% confidence interval for population proportion is given by:
The sample size is, <em>n</em> = 1483.
The 95% confidence interval for the population proportion of people who say that a car is a necessity is,
<em>CI</em> = (0.83, 0.89)
A (1 - <em>α</em>)% confidence interval for a population parameter implies that there is (1 - <em>α</em>) probability that the true parameter value is contained in the interval.
Or, there is (1 - <em>α</em>)% confidence that the confidence interval consists of the true population parameter value.
The 95% confidence interval for the population proportion of people who say that a car is a necessity implies that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89) with a probability of 0.95.
Or, there is 95% confidence that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89).
