Answer:
The correct answer is "16.987, 20213".
Step-by-step explanation:
Given that,
![n=30](https://tex.z-dn.net/?f=n%3D30)
![\bar x=18.6](https://tex.z-dn.net/?f=%5Cbar%20x%3D18.6)
![s = 5.2](https://tex.z-dn.net/?f=s%20%3D%205.2)
![df=30-1](https://tex.z-dn.net/?f=df%3D30-1)
![=29](https://tex.z-dn.net/?f=%3D29)
![\alpha = 0.10](https://tex.z-dn.net/?f=%5Calpha%20%3D%200.10)
By using the table, the critical values of t will be:
= ![\pm 1.699](https://tex.z-dn.net/?f=%5Cpm%201.699)
Now,
The confidence interval will be:
= ![\bar x \pm \frac{t\times s}{\sqrt{n} }](https://tex.z-dn.net/?f=%5Cbar%20x%20%5Cpm%20%5Cfrac%7Bt%5Ctimes%20s%7D%7B%5Csqrt%7Bn%7D%20%7D)
By putting the values, we get
= ![18.6 \pm \frac{1.699\times 5.2}{\sqrt{30} }](https://tex.z-dn.net/?f=18.6%20%5Cpm%20%5Cfrac%7B1.699%5Ctimes%205.2%7D%7B%5Csqrt%7B30%7D%20%7D)
= ![16.987,20.213](https://tex.z-dn.net/?f=16.987%2C20.213)

Answer:
8 lb
Step-by-step explanation:
The original weight W increased by 12% is ...
W + 12%·W = 8.96
1.12W = 8.96
W = 8.96/1.12 = 8.00
The kitten's weight a month ago was 8.0 pounds.
8.5x + 55 = 123
You would use the formula: mx + b = y
The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.
