if you are adding two fractions that are both greater than 1/2 what must be true about the sum? Give three examples to support y
Sunny_sXe [5.5K]

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

Hope this helps

PLZ HELP ASAP RADIANS AND ARC LENGTH
velikii [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>

6 times a number is 27 less than the square of that number. Find the positive solution.
Sedaia [141]

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

A certain change in a process for manufacture of component parts is being considered. Samples are taken using both the existing
Katyanochek1 [597]

Answer:

a) The confidence interval is 0.00\leq\pi_1-\pi_2\leq0.02.

Step-by-step explanation:

We have to calculate a confidence interval (CI) of a difference of proportions.

For the existing procedure, the proportion is:

p_1=75/1500=0.05

For the new procedure, the proportion is:

p_2=80/2000=0.04

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

s=\sqrt{\frac{p_1(1-p_1)}{n_1} +\frac{p_2(1-p_2)}{n_2} }\\\\s=\sqrt{\frac{0.05(1-0.05)}{1500} +\frac{0.04(1-0.04)}{2000} }=\sqrt{ 0.000032 + 0.000019 }=\sqrt{  0.000051 }\\\\s=0.007

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

Then, the CI is:

(p_1-p_2)-z*\sigma \leq\pi_1-\pi_2\leq(p_1-p_2)+z*\sigma \\\\(0.05-0.04)-1.64*0.007\leq\pi_1-\pi_2\leq(0.05-0.04)+1.64*0.007\\\\0.01-0.01\leq\pi_1-\pi_2\leq0.01+0.01\\\\0.00\leq\pi_1-\pi_2\leq0.02

When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88
Natali5045456 [20]
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!
