The diameter of the circle is needed. But to solve, you would simply multiply the diameter of the circle by pi (3.14).
Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
Answer: There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Step-by-step explanation:
Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.
Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).
i.e. A person can be 90% confident that the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).
Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Start by graphing y = |x|. Its vertex is at (0,0), and the graph opens up.
Now translate the entire graph 4 units up. The new vertex will be at (0,4). Draw an empty circle around this point.
Darken the graph of y = |x|+4 ONLY for the part which is left of the y-axis.
Now plot a dark dot at (0,4). Draw a dark, horiz. line from that dot to the right.
That's it!
