Step-by-step explanation:
Found the circumference then quartered. Can I have brainiest I need one more to upgrade.
If it is #17 this:
the class sold 45 sandwiches and collected $150.75, all you need to do is divide.
150.75/45
= 3.35
$3.35 per sandwitch
Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
Answer:
2 one.
Step-by-step explanation:
Answer:
121
Step-by-step explanation:
Given data as per the question
Standard deviation =
= 840
Margin of error = E = 150
Confidence level = c = 95%
For 95% confidence, z = 1.96
based on the above information, the minimum number of clients surveyed by the travel agent is
![n = (\frac{z\times \sigma}{E})^2](https://tex.z-dn.net/?f=n%20%3D%20%28%5Cfrac%7Bz%5Ctimes%20%5Csigma%7D%7BE%7D%29%5E2)
![= (\frac{1.96\times 840}{150})^2](https://tex.z-dn.net/?f=%3D%20%20%28%5Cfrac%7B1.96%5Ctimes%20840%7D%7B150%7D%29%5E2)
= 120.47
= 121
hence, the 121 number of clients to be surveyed
Therefore we applied the above formula to determine the minimum number of clients
