Answer:
10x+2y
Step-by-step explanation:
combine like terms
Answer:
y = 5
Step-by-step explanation:
Expand the logarithm:

_____
You can also take the antilog first:
5y = y²
y(y -5) = 0 . . . . . subtract 5y, factor
y = 0 or 5 . . . . . y=0 is not a viable solution, so y=5.
I think that it would be true, but, don't make me promise that it's right, lol XD
Answer:
Answer is c
Step-by-step explanation:
In hypothesis testing whether to accept or reject null hypothesis, normally we find one method as using confidence interval. If the test statistic lies within confidence interval, we accept otherwise we reject.
For arriving confidence intervals we add and subtract margin of error from the mean we use in null hypothesis.
Margin of error = std error * critical value of test (Z or t etc)
For the same std deviation, std error = std dev/sq rt of sample size
Thus std error is inversely proportional to the square root of sample size.
If n becomes larger, std error becomes smaller and vice versa.
So margin of error increases for smaller sample size.
Since we have to select confidence level from a small sample, we have to select one which has the greatest margin of error=18
Hence answer is
c) 71%(+/-18%)
The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides
Step-by-step explanation:
Given inequality that the teacher wrote is:

Solving an inequality means that the variable should be isolated on left side of the inequality.
So multiplying both sides by 6

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides
