Answer:
A = 735 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 35 and h = 21 , then
A = 35 × 21 = 735 cm²
Answer:
Step-by-step explanation:
Given data:
![\mu = 473](https://tex.z-dn.net/?f=%5Cmu%20%3D%20473)
standard deviation is ![\sigma= 28](https://tex.z-dn.net/?f=%5Csigma%3D%20%2028)
As distribution is normal in shape and values are symmetrical
The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean
so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval
![= \mu + 2\times \sigma](https://tex.z-dn.net/?f=%3D%20%5Cmu%20%2B%202%5Ctimes%20%5Csigma)
![= 473 + 2\times 28 = 529](https://tex.z-dn.net/?f=%3D%20473%20%2B%202%5Ctimes%2028%20%3D%20529)
almost 0.15% of students spent more amount is 529

r=21m
<h2>Hello!</h2>
The answer is:
The domain of the function is all the real numbers except the number 13:
Domain: (-∞,13)∪(13,∞)
<h2>Why?</h2>
This is a composite function problem. To solve it, we need to remember how to composite a function. Composing a function consists of evaluating a function into another function.
Composite function is equal to:
![f(g(x))=(f\circ} g)(x)](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%28f%5Ccirc%7D%20g%29%28x%29)
So, the given functions are:
![f(x)=x+7\\\\g(x)=\frac{1}{x-13}](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B7%5C%5C%5C%5Cg%28x%29%3D%5Cfrac%7B1%7D%7Bx-13%7D)
Then, composing the functions, we have:
![f(g(x))=\frac{1}{x-13}+7\\](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%5Cfrac%7B1%7D%7Bx-13%7D%2B7%5C%5C)
Therefore, we must remember that the domain are all those possible inputs where the function can exists, most of the functions can exists along the real numbers with no rectrictions, however, for this case, there is a restriction that must be applied to the resultant composite function.
If we evaluate "x" equal to 13, the denominator will tend to 0, and create an indetermination since there is no result in the real numbers for a real number divided by 0.
So, the domain of the function is all the real numbers except the number 13:
Domain: (-∞,13)∪(13,∞)
Have a nice day!
