Answer:
If you are adding to fractions that are both greater than 1/2, the sum will be greater than 1.
Step-by-step explanation: 1/2 + 1/2 =1
Since both fractions are greater, obviously the sum will too.
Examples: 2/3+3/4= 1 5/12 4/6+6/9= 1 1/3

<span>The arc length by definition is given by:</span>
<span> S = R * theta</span>
<span> Where,</span>
<span> R: radio</span>
<span> Theta: central angle</span>
<span> Substituting values we have:</span>
<span> S = 10 * (3/2) pi</span>
<span> Rewriting we have:</span>
<span> S = 5 * (3) pi</span>
<span> S = 15pi</span>

Answer:
9
Step-by-step explanation:
6n = n² - 27
n² - 6n - 27 = 0
n² - 9n + 3n - 27 = 0
n(n - 9) + 3(n - 9) = 0
(n - 9)(n + 3) = 0
n = -3, 9
Answer:
a) The confidence interval is
.
Step-by-step explanation:
We have to calculate a confidence interval (CI) of a difference of proportions.
For the existing procedure, the proportion is:

For the new procedure, the proportion is:

To calculate the CI, we need to estimate the standard deviation

For a 90% CI, the z-value is 1.64.
Then, the CI is:

Uh, so, you're median is 81 already.
Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.
However, if you're trying to add a number in, adding 81 as it is would work as well.
Hope this helps!
