It’s 28!!, good luck on whatever your doing
In order for you to understand this question you have to know what the unit rate is. In order to find it you divide 75 by 3 which is 25 so you know that 1 ticket will cost 25$ so then you multiply that 25 times 5 to get your final answer which is 125.
Answer:
√72=2⋅3√2.
Step-by-step explanation:
This is your answer I am pretty sure this is correct.
If not please let me know.
{ 3-y=2x
{ x+1/2y=3/2
{ -y=2x-3
{ 1/2y=3/2-x
{ y=-2x+3
{ y=3-2x
-2x+3=3-2x
(x,y) = (x,-2x+3)
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
