Answer:
b. There is a 95% chance that the true proportion of teenagers who use Mybook as their primary social network site is in the interval (0.2964, 0.9036).
Step-by-step explanation:
Hello!
In general, a 95% confidence interval for the population proportion can be interpreted as: There is a 95% chance (or confidence) that the interval will contain the true value of the proportion.
(Remember the confidence level of 95% means that if you were to make 100 intervals for the population proportion, 95 of them will contain its true value)
The estimated parameter is the population proportion of teenagers that use Mybook as their primary social network site.
With this in mind then you can say that there is a 95% probability that the interval (0.2964, 0.9036) will contain the true value of the proportion of teenagers that use Mybook as their primary social network site.
The correct answer is: b

Answer:
x=20
Step-by-step explanation:
Well we know the right angle is 90 so...
And we also know that all the angle of a triangle add up to 180°.
Knowing this you can subtract 40° and 90°, this gives you 50°...
Then you can substitute 20° for x and then it will be 2(20°)+10°
Simplify and get 40°+10°
This equals 50° degrees
You then add that all up and you get 180°, this mean the answer is correct!
Hope this helps!
