This I think could be technically answered in a couple of ways. Fill the 4 gallon bucket up and then fill the 7 gallon bucket up 1/7 of the way. Or fill the 4 gallon bucket up and transfer to the 7 gallon bucket and fill the 4 gallon bucket up 1/4 of the way. Either way the 1/4 or the 1/7 will be a close estimate to get your 5 gallon bucket. I hope this helps.
Answer:
$105 (Make sure to read the explanation)
Step-by-step explanation:
120.45 + 95.75 + 105.32 + 140.25 + 89.68 + 101.32 = 652.77
652.77 ÷ 6 = 108.795
I think the mean as her budget is a tiny weny too high so I think $105 is a good enough budget. Feel free to change it.
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)
Answer:
Critical value is 1.318 and the confidence interval is 29.357 to 33.042
Step-by-step explanation:
n = 25
x = 31.2
s = 6.99
Degree of freedom = n-1= 25-1 =24
Confidence level = 0.8
So, α = 1- 0.8= 0.2
t critical = ![t_{\frac{\alpha}{2},df}=t_{\frac{0.2}{2},24}=t_{0.10,24}=1.318](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%2Cdf%7D%3Dt_%7B%5Cfrac%7B0.2%7D%7B2%7D%2C24%7D%3Dt_%7B0.10%2C24%7D%3D1.318)
Formula of confidence interval :
