Answer:

C- Figure STOP is congruent to figure S'T'O'P'.

Step-by-step explanation:

1- I got it right on my test

2- If you flipped it they would look exactly the same only backwards.

(Hope that makes sense. Sorry, i'm not good at explaning things)

Kirsten runs an experiment for her Research Methods class in which she studies vocabulary learning in introductory-level French
Sidana [21]

Answer:

Kristen should use the paired <em>t</em>-test.

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or paired-samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference between these two means.

We use the paired t-test if we have two measurements on the same item, person or thing. We should also use this test if we have two items that are being measured with a unique condition.

For instance, an experimenter tests the effect of a medicine on a group of patients before and after giving the doses.

In this case, Kristen assesses the students' knowledge of French vocabulary at the start of the semester and then again at the end of the semester.

So, she collects data before and after the semester for vocabulary learning in introductory-level French class.

Thus, she is using a paired <em>t</em>-test to analyze whether the French students significantly increased their knowledge of French vocabulary.

The hypothesis is defined as:

<em>H₀</em>: There is no difference between the two means, i.e. <em>μ</em>₁ - <em>μ</em>₂ = 0.

<em>Hₐ</em>: There is a significant difference between the two means, i.e. <em>μ</em>₁ - <em>μ</em>₂ ≠ 0.

The test statistic is:

t =  Sample mean difference ÷ (Standard deviation of difference/ Sample size)

Thus, Kristen should use the paired <em>t</em>-test.

Divide the following fractions and reduce to lowest terms 2/3 divided by 4/5
pshichka [43]
Well to divide 2 fraction you first have to find a least common number between the 2 bottom numbers in the fractions, we know automaticall that 15 fits in both the 3 and the 5. now u have to find out what to multiply by each number to get 15, for example what number do you multiply by 3 to get 15?? well it will be 5, so go ahead and multiply it by the fraction (note that what you do  in the bottom you have to do in the top) this will give you 10/15, because I multiplied the top and bottom number by 5... lets try the other one what number do you multiply by 5 to get 15?? well it will be 3 so go ahead and multiply that to get 12/15.. now add the top numbers (note that the bottoms always stay the same, you never add or subtract them) when you do you will get 22/15, now you have to see if you can simplify it any further in this case you can't so your final answer is 22/15

Hope this helps

Answer: I won't bother explaining cause you only want the answer

Step-by-step explanation:

x, adds
