Answer, Step-by-step explanation:
According to the exercise, we evaluate the delivery time of a courier company and we will hypothesize the best case with a sample size of 10, which is:
Small sample T test for single mean
The hypothesis that we will develop will be the following:
null hypothesis = mu> = 6
hypothesis alternativa: <6
6(7+5) + 3
Hope this helps :)
To check:
PEMDAS
7+5 is 12
6(12) + 3
72 + 3
75
Answer:

Step-by-step explanation:
Hi there!
Equation of a circle:
where the circle is centered at (h,k) and the radius is r
<u>1) Plug in the given center (7,0)</u>
![(x-7)^2+(y-0)^2=r^2\\(x-7)^2+y^2=r^2](https://tex.z-dn.net/?f=%28x-7%29%5E2%2B%28y-0%29%5E2%3Dr%5E2%5C%5C%28x-7%29%5E2%2By%5E2%3Dr%5E2)
<u>2) Plug in the radius (1)</u>
![(x-7)^2+y^2=1^2\\(x-7)^2+y^2=1](https://tex.z-dn.net/?f=%28x-7%29%5E2%2By%5E2%3D1%5E2%5C%5C%28x-7%29%5E2%2By%5E2%3D1)
