Answer:

In order to tell if these are congruent triangles we would need to know if angles Y and V were congruent, angles X and W are congruent or if segments XU and WU were congruent.

Step-by-step explanation:

Any of these would work because you can use two different methods to telling that these are congruent triangles.

The first method is called side-angle-side. In it you need two side lengths that are congruent with a congruent angle in the middle. Since we already know that the right angle in the middle is congruent, and we know YU and VU are congruent, we would just need to know the additional side to prove congruence.

The second method is called angle, angle side. In this we need to know that two angles in a row are congruent followed by a side. Since we know the middle angle is the same, knowing either other angles would give us this method as well.

Answer:

D) P-045 says that a response this small or smaller would be seen in sample data almost half the time when in fact there is no effect in the entire population of rats. That is, a response this size would often happen just by chance.

Step-by-step explanation:

The P-value represents the probability of getting the test sample results given that the null hypothesis is true.

A P-value that is low enough (smaller than the significance level) gives statistical evidence to support that the null hypothesis is not true.

In this case,  a P-value of 0.45 does not represent a strong evidence against the null hypothesis, as there is 45% of chances of getting this sample results if the null hypothesis is true.

In this case, as we talk about differences ("no difference was seen" between the two groups), we know that the sample difference has not been large enough to be proved statistically significant.

So the right answer is Option d).

I NEED HELP GUYS PLEASE!!!! AP STATISTICS
julsineya [31]

Just count how many times a given age appears in the data. If my eyes aren't deceiving me, I count

• 26: 3

• 27: 5

• 28: 5

• 29: 5

• 30: 2

• 31: 1

• 33: 4

Then the second most frequent age in the data is 33, and the least frequent is 31.

The points (-2,-10) and (-1, v) fall on a line with a slope of 8. What is the value of v?
Nutka1998 [239]
I think the answer is -2

Following the rule of “rise over run”, the fraction form of the gradient it 8 over 1 (8/1)
This means you move up 8 units, and move across 1 unit.
The final coordinate is (-1, -2)
V = -2

Hope this helps!
