28=12+x
28 represents how tall he will get, 12 represents how tall he is in inches, and x is how much he still has left to grow! Hope it helps!
Answer: 38.41 minutes
Step-by-step explanation:
The standard error for the difference in means is given by :-
![SE.=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma^2_2}{n_2}}](https://tex.z-dn.net/?f=SE.%3D%5Csqrt%7B%5Cdfrac%7B%5Csigma_1%5E2%7D%7Bn_1%7D%2B%5Cdfrac%7B%5Csigma%5E2_2%7D%7Bn_2%7D%7D)
where ,
= Standard deviation for sample 1.
= Size of sample 1.
= Standard deviation for sample 2.
= Size of sample 2.
Let the sample of Latino name is first and non -Latino is second.
As per given , we have
![n_1=9](https://tex.z-dn.net/?f=n_1%3D9)
![n_2=14](https://tex.z-dn.net/?f=n_2%3D14)
The standard error for the difference in means will be :
![SE.=\sqrt{\dfrac{(82)^2}{9}+\dfrac{(101)^2}{14}}](https://tex.z-dn.net/?f=SE.%3D%5Csqrt%7B%5Cdfrac%7B%2882%29%5E2%7D%7B9%7D%2B%5Cdfrac%7B%28101%29%5E2%7D%7B14%7D%7D)
![SE.=\sqrt{\dfrac{6724}{9}+\dfrac{10201}{14}}](https://tex.z-dn.net/?f=SE.%3D%5Csqrt%7B%5Cdfrac%7B6724%7D%7B9%7D%2B%5Cdfrac%7B10201%7D%7B14%7D%7D)
![SE.=\sqrt{747.111111111+728.642857143}](https://tex.z-dn.net/?f=SE.%3D%5Csqrt%7B747.111111111%2B728.642857143%7D)
![SE.=\sqrt{1475.75396825}=38.4155433158\approx38.41](https://tex.z-dn.net/?f=SE.%3D%5Csqrt%7B1475.75396825%7D%3D38.4155433158%5Capprox38.41)
Hence, the standard error for the difference in means =38.41 minutes
The provided function y=cos(x)/x is an odd function because f(-x) = -f(x) then it is an odd function.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
![\rm y = \dfrac{cos(x)}{x}](https://tex.z-dn.net/?f=%5Crm%20y%20%3D%20%5Cdfrac%7Bcos%28x%29%7D%7Bx%7D)
From the definition of the even and odd function:
If f(-x) = f(x) then it is an even function
If f(-x) = -f(x) then it is an odd function
![\rm y(-1) = \dfrac{cos(-x)}{-x}](https://tex.z-dn.net/?f=%5Crm%20y%28-1%29%20%3D%20%5Cdfrac%7Bcos%28-x%29%7D%7B-x%7D)
![\rm y(-1) = -\dfrac{cos(x)}{x}](https://tex.z-dn.net/?f=%5Crm%20y%28-1%29%20%3D%20-%5Cdfrac%7Bcos%28x%29%7D%7Bx%7D)
cos(-x) = cosx
Thus, the provided function y=cos(x)/x is an odd function because f(-x) = -f(x) then it is an odd function.
