Well 2 tens and 6 ones so do to tens then 6 ones u get 26
Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-
![E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=E%3Dt_%7B%5Calpha%2F2%7D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : ![\alpha=1-0.90=0.10](https://tex.z-dn.net/?f=%5Calpha%3D1-0.90%3D0.10)
By using the t-distribution table ,
Critical value : ![t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743](https://tex.z-dn.net/?f=t_%7Bn-1%2C%20%5Calpha%2F2%7D%3Dt_%7B21%2C0.05%7D%3D%201.720743)
Standard deviation: ![\sigma=4](https://tex.z-dn.net/?f=%5Csigma%3D4)
Then, we have
![E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467](https://tex.z-dn.net/?f=E%3D%281.720743%29%5Cdfrac%7B4%7D%7B%5Csqrt%7B22%7D%7D%3D1.46745456106%5Capprox1.467)
Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
Answer:
If she wants to run 16 more miles in four days (30 miles minus already done 14 miles) she can run 4 miles a day for the next four days. 4 miles a day.

Answer:
y=7/1x+26
Step-by-step explanation:
I didnt fully understand what the questions was asking. all I got from it was slope-intercept and even then it didn't make sense so I created the equation that goes throw those 2 points and added the y intercept to it.
hope this somehow helped...
