Answer: (0.685, 0.735)
Explanation:
First, we will compute the confidence level of the given:
They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.
The confidence interval would then be:
Therefore, the confidence interval would then be (0.685, 0.735)
If D is the center of the circle, ∠ADB = 70°, as that is where the arc gets its measure.
If D is on the circle and not on the arc, ∠ADB = 35°, half the measure of the arc's central angle.
If D is on arc AB, then ∠ADB = 145°, half the measure of the corresponding central angle.
If D is inside or outside the circle (and not one of the above), we need to know more about the measures of arcs intercepted by lines AD and BD.
Step-by-step explanation:
2x = 18
Divide both sides by 2
x = 9
Answer:
this is a hard one buddy
Step-by-step explanation:
-- Do anything you need to do in order to get 'x' all by itself on one side and everything else on the other side.
-- As soon as you do anything to one side of the equation, you must immediately do the same thing to the other side.
-- That's the whole book on solving any equation with a single variable.
