pizza?
Step-by-step explanation:
tbh I'm confused soooo
The formulas are already given, all you have to do is plot them each separately and you will find that they crooks each other, the point of intersection is your solution.
c-de=9cm; ef=15cm hope this helps
Answer: (22.41, 25.59)
Step-by-step explanation:
The t-critical value with 17 degrees of freedom for a 95% confidence interval is : 2.11
Sample mean = 24
Standard deviation = 3.2
Standard error of mean = s / √ n
Standard error of mean = 3.2 / √ 18
SE = 3.2/4.2426
Standard error of mean 0.7542
Confidence interval 24-(0.7542)(2.11) = 22.41 and
24+(0.7542)(2.11) =25.59
