Considering the situation described, the confidence interval is given by:
(0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.
Then, the bounds of the interval are given by:

Answer:
you would use 20 quarters and 14 dimes
Step-by-step explanation:
25*20=500
10*14=140
5.00+1.40=6.40
The answer is 74. I'm 100% sure.
Answer:
a) True
Step-by-step explanation:
The left side is where the corner or 0 is, so if a line goes up towards the right, the answer would be positive.
well, we know that θ is in the III Quadrant, where the sine is negative and the cosine is negative as well, or if you wish, where "x" as well as "y" are both negative, now, the hypotenuse or radius of the circle is just a distance amount, so is never negative, so in the equation of cos(θ) = - (2/5), the negative must be the adjacent side, thus
