Answer:
Tip = $10.52
Tax = $4.21
Total bill = $67.33
Step-by-step explanation:
We are given the following in the question:
Pre-tax bill = $52.60
Tip to waiter = 20% of the pre-tax amount
Tip to waiter =
Thus, $10.52 was given to waiter.
Tax on bill = 8% of the pre-tax amount
Tax =
Thus, tax on bill was $4.21.
Total bill =
Pre-tax amount + Tax + Tip
Thus, the total bill is $67.33
Answer:
138 because if u add 60+78 it equals 138
Answer:
When conducting an analysis of variance analysis on a set of samples and the null hypothesis is rejected, we can test for the difference between treatment can be tested with the aid of a t-test. This is employed when 2 related groups are involved. Independent sample, paired sample or one-sample t-test can be conducted.
Step-by-step explanation:
A t-test is a test statistic used to make inferences that determine the differences that exist statistically between 2 related groups. It tells us if the 2 groups tested are from the same population. There are 3 types of t-test namely independent sample t-test, paired-sample t-test and one-sample t-test
Considering the slope of the lines, it is found that the lines going through the points are neither parallel nor perpendicular.
<h3>When are lines parallel, perpendicular or neither?</h3>
The slope, given by <u>change in y divided by change in x</u>, determines if the lines are parallel, perpendicular, or neither, as follows:
- If they are equal, the lines are parallel.
- If their multiplication is of -1, they are perpendicular.
- Otherwise, they are neither.
In this problem, the slopes are given as follows:
- m1 = (5 - 3)/(-2 - 8) = -2/10 = -1/5 = -0.2.
- m2 = (-10 - (-5))/(-1 -(-2)) = -5/1 = -5.
The multiplication is of 1, not -1, hence they are neither parallel nor perpendicular.
