Answer:
271 people
Step-by-step explanation:
Margin of error = critical value × standard error
At 90% confidence, the critical value is 1.645.
Standard error for a proportion is s = √(p (1 − p) / n).
0.05 = 1.645 √(0.52 (1 − 0.52) / n)
n = 271
Answer:
Plot the points (0,0) and (1,3) to make the line.
Step-by-step explanation:
We know that a linear equation is y=mx+b, m is the slope and b is the y-intercept. We can see that the slope is m=3, and there is no b meaning b=0. Since the y-intercept is 0 we can start from the origin (0,0). The slope is 3/1 or known as rise/run. You go up 3 and go right 1, making the second point (1,3). This should work.
Answer:
Step-by-step explanation:
The answer is B. 18
Explanation:
We know that a square has 4 right angles. A right angle is 90°.
5x° = 90°
5(18)° =90°
90°=90°
