Answer:
the measure of supplementary angles must add up to 180
Step-by-step explanation:
complementary angles add up to 90°
angles on a straight line are supplementary angles which add up to 180°
First, convert the 65% to a real mathematical number. For percents, this is always done by dividing the 65% by 100%, or 65% / 100% = 0.650.
Second, find out what 65% of $60 is. This is the amount of the sale discount. This is always found by mulitplying 0.650 by the item's cost $60, like this:
0.650 x $60 = $39.00.
So for this sale, you'll save $39.00 on this item.
This means, the cost of the item to you is
<span>$60 - $39.00 = $21.00.</span>
Answer:
It's a function
Step-by-step explanation:
Functions can only have one output for each input. And since all the x values for each point are different, there is only one output (y-value) for each input(x-value).
The one that has -7 and -13 on the first line.
Itd be the 2nd answer from the top.
The t-test is a type of inference statistic used to determine if there is a significant difference between the means of two groups that may be related to a particular characteristic. The t-test is one of many tests used to test statistical hypotheses.
Inference statistics have two main purposes. Estimates for population groups (for example, the average SAT score for all 11th graders in the United States). Hypothesis testing to draw inferences about the population
One-way ANOVA is a common method for comparing three or more group means. The usual goal is to determine if the mean (or median) of at least one group is different from the other. Subsequent multiple comparison tests are often used to determine where differences occur.
