<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51
a = 85 and b = 51</span>
' 9 + 10 ' is a simple exercise in addition. Its solution is 19 .
There is junk floating around the internet saying that 9+10=21.
That statement is false, and the arithmetic is wrong.
The whole thing is a joke. If you ask someone to prove it, they will
perform a demonstration with Roman numerals, but the way they handle
the Roman numerals is itself defective, and they're hoping you won't notice.
Answer:
The number of people surveyed was 330.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population proportion is:

The margin of error for this interval is:

The information provided is:

The critical value of <em>z</em> for 94% confidence level is, <em>z</em> = 1.88.
*Use a <em>z</em>-table.
Compute the value of <em>n</em> as follows:

![n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}](https://tex.z-dn.net/?f=n%3D%5B%5Cfrac%7Bz_%7B%5Calpha%2F2%7D%5Ctimes%20%5Csqrt%7B%5Chat%20p%281-%5Chat%20p%29%7D%7D%7BMOE%7D%5D%5E%7B2%7D)
![=[\frac{1.88\times \sqrt{0.37(1-0.37)}}{0.05}]^{2}\\\\=(18.153442)^{2}\\\\=329.5475\\\\\approx 330](https://tex.z-dn.net/?f=%3D%5B%5Cfrac%7B1.88%5Ctimes%20%5Csqrt%7B0.37%281-0.37%29%7D%7D%7B0.05%7D%5D%5E%7B2%7D%5C%5C%5C%5C%3D%2818.153442%29%5E%7B2%7D%5C%5C%5C%5C%3D329.5475%5C%5C%5C%5C%5Capprox%20330)
Thus, the number of people surveyed was 330.
Answer: 121.5 pi in^3 or 381.7 in^3
Step-by-step explanation:
Volume of a cylinder = pi r^2(h)
Radius = 4.5 in, Height = 6 in
pi (4.5)^2(6)
pi(20.25)(6)
121.5 pi in^3 or 381.7 in^3
Step-by-step explanation:
subtracting equation i from it got cropped
so the answer for x is 7 and y is -17
hope this helps. :)
