12/15 games have been won then they won 3 which makes it then 15/18 because the denominator is how many games they've played while the numerator is how many games they one.
Cross multiply both...
divide each side by 18 to make the x by itself
Which gives you x=83.333%
Answer:
Accept the claim that mean = 8.2oz.
Step-by-step explanation:
Given that a company claims that its coffee cans contain 8.2 ounces of coffee, on average.
To check this, normally large samples are drawn and sample mean is calculated
Then hypotheses created as
H0: Mean = 8.2
Ha: Mean not equals 8.2
The std deviation of sample is found out and then 95% confidence interval is calculated.
If the sample mean falls within 95% confidence interval, then we are 95% confident that for large samples, the sample mean would fall within this interval. Also the claim can be accepted.
Hence conclusion is accept null hypothesis that mean = 8.2 oz.

Answer:
![\sqrt[3]{5x+10}=5 / ^{3}\\ 5x+10=125\\5x=115/:5\\x=23](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%2B10%7D%3D5%20%2F%20%5E%7B3%7D%5C%5C%20%205x%2B10%3D125%5C%5C5x%3D115%2F%3A5%5C%5Cx%3D23)
If you mean that :![\sqrt[3]{5x}+10=5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5)
this is
![\sqrt[3]{5x}+10=5 /^{3} \\5x+1000=125\\5x=-875/:5\\x=-175](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5%20%2F%5E%7B3%7D%20%5C%5C5x%2B1000%3D125%5C%5C5x%3D-875%2F%3A5%5C%5Cx%3D-175)
