Answer:
Step-by-step explanation:
Sean buys some T-shirts for $12 each and the same number of belts for $7.50 each. Write an expression in the simplest form that represents the total amount.
So n represents the same number for t-shirts and belts.
Therefore n x 12.50 + n x 7.50 OR n(12.50+7.50)
The problem the student made was that they multiplied 12 times n plus 7.50. They forgot to multiply n times 7.50.
An expression that represents the total amount spent is 12n + 7.50n
Hope this helps!
'Parallel' means parallel TO something else. A single line all by itself
is not "a parallel line", until we know the other line that it's parallel TO.
There are an infinite number of lines that pass through (0, -2).
Give us another line, and we'll find the one that's parallel to it.

Answer:
False
Step-by-step explanation:?
The hypothesis tests compare weather an event is meant to alter a population mean results, for example, a scientist experiment might have or not have a significant effect over the population results. The test aims to reject the null hypothesis, so what it really want to find out is if the alternative Hypothesis H1 is likely true. The null hypothesis is the probability that the results are not due to chance – if it’s rejected, then the results are due to chance.The level of significance , or so called p-value, is the probability that the null hypothesis (H0) happen , If p is very small then the null hypothesis is rejected - isn’t true- and the alternative Hypothesis is accepted. A higher P value implies a higher probability than results are not happening so that the H0 is accepted and H1 rejected. The null Hypothesis will normally will rejected when the level of significance are either lower than 0.05 or 0.01, the lower P value the higher the level of confidence that the results are due to chance.
Since the first part of the statement (A p is the probability that the results are not due to chance) is correct, and the second part is wrong (…the probability that the null hypothesis (H0) is false), the total statement is false. The correct statement would be as follows : A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is true.
