A graphing calculator shows the rocks are at the same height 1.5 seconds after they are released.
That height is 3.975 meters.
_____
f(x) = g(x)
-4.9x^2 +15 = -4.9x^2 +10x
15 = 10x . . . . . . . . . . . . . . . . . . add 4.9x^2
1.5 = x . . . . . . . . . . . . . . . . . . . divide by 10
f(1.5) = -4.9*2.25 +15 = 3.975
That height is 3.975 meters.

For the first letter drawn, there are no conditions/restrictions we need to consider. So, the number of ways to draw an i is:
For the second draw, the i is not replaced. That means, we've shrunk the sample space because we're dealing with less elements for the second draw. Firstly, one i disappears since we picked an "i" and there are 10 elements left, not 11.
Thus, to draw the second i, we have:
For the second draw, the i is not replaced. That means, we've shrunk the sample space because we're dealing with less elements for the second draw. Firstly, one i disappears since we picked an "i" and there are 10 elements left, not 11.
Thus, to draw the second i, we have:
Answer: (0.641, 0.719)
Step-by-step explanation:
The confidence interval for population proportion is given by :-
Given : Level of significance :
Then , significance level :
Since , sample size : , i.e. a large sample.
Critical value :
Also, the proportion of individuals plan on voting yes :-
Then , the confidence interval at the 90% confidence level will be :-
Hence, the confidence interval at the 90% confidence level= (0.641, 0.719)
