T-scores show how many standard deviation units an examinee's score differs from the mean. Because T-Scores have a mean of 50 and a standard deviation of 10, any T-Score may be directly interpreted.
What is T-score?A t-score (sometimes known as a t-value) is the number of standard deviations from the mean of the t-distribution. The test statistic used in t-tests and regression testing is the t-score. It may also be used to represent how distant an observation is from the mean when the data follows a t-distribution. A t test is a statistical test used to compare two groups' means. It is frequently used in hypothesis testing to assess whether a procedure or treatment has an effect on the population of interest, or whether two groups vary.
Here,
T-scores reflect how many standard deviation units an examinee's score is above or below the mean. Because T-Scores always have a mean of 50 and a standard deviation of 10, any T-Score may be directly interpreted.

So there is a square and 4 triangles.
You first, find the area of the square.
You then get: 35 x 48 = 1,680
Then you need to add the triangles.
Because we have 2 triangles on each side the area formula of a triangle in which is 1/2 times by the base and height can be solved by just B * H.
Doing that you can get: 48 * 7 = 336
Because you have 2 triangles, the final area results in:
1,680 + 336 * 2 = 2,352

What is the area of the figure below?
3 in.
3 in.
5 in.
5 in.
3 in.
3 in.
7 in.
Answer:
68 inches squared
Step-by-step explanation:
First, let's find the area of the squares at the top and bottom. Area for a square is:
L * W = A
Plug in the values...
3 * 3 = 9
Therefore, the area of the two squares combined is 18 inches (since 9 + 9 = 18). Now, the hexagon in the middle, which is the hardest part. We will have to separate it into 4 triangles and a rectangle, for simplification. We need to find the base widths of the triangles, which are:
7 (total width) - 3 (middle width) / 2 (because there are two sides)
So it is:
(7 - 3)/2
4/2 = 2
So, the base of the triangle is two inches. We also know that the height of the triangle is five inches. The formula for the area of a triangle is:
(B * H)/2 = A
Fill it in...
(2 * 5)/2
10/2 = 5 inches
So, the area of each triangle is 5 inches. Since there are four triangles, we need to do:
5 * 4 = 20 inches
That means that all of the triangles combined is 20 inches. Lastly, we need the middle part of our hexagon. It is 10 inches tall, and three inches wide. So...
L * W = A
10 * 3 = 30
So, that means that the area of the hexagon is:
30 + 20 = 50
Plus, the two squares from the beginning:
50 + 18 = 68 inches squared
Therefore, the area of the figure is 68 inches. Hope this helps you!

If you spun the spinner 100 times, how many times do you predict that you would spin a number less than 5 on a spinner of 1-6
Answer:
67 times
Step-by-step explanation:
Spinner's sample space = (1, 2, 3, 4, 5, 6)
Number less than 5 = (1, 2, 3, 4)
Total possible outcomes = 6
Required outcome = 4
P(number less than 5) = required outcome / Total possible outcomes
P(number less than 5) = 4 /6 = 2/3
Number of spins = 100
Predicted Number of times a number less than less than 5 is spurn in 100 spins :
100 * 2/3
= 66.666
= 67 times

ANSWER ASAP!!!!!!!!!!!!!!!!!!!!! Reflect (4, -4) over the x-axis. Then translate the result to the right 3 units. What are the coordinates of the final point? NO FILES PLEASE
Answer:
(7,4)
Step-by-step explanation:
The rule for reflecting over the x-axis is (x,y) -> (x,-y)
If you apply that to your point, you get (4,4)
When doing this translation, you add the 3 to the number you have in the x. This will give you (7,4).

A person swims 11 miles downstream in the same time they can swim 7 miles up stream. The speed of the current is 4 miles per hour.
These situations can be represented by the equations
Downstream: t=11/s+4 Upstream:t=7/s-4,
where t stands for time and s is the speed of the swimmer. What is the speed of the swimmer swimming in still water?
Answer:
s = 18 mph
Step-by-step explanation:
At downstream, time is; t = 11/(s+ 4)
At upstream, time is; t = 7/(s - 4)
Since they both are passed in the same time, then ;
11/(s+ 4) = 7/(s - 4)
Cross Multiply to get;
11(s - 4) = 7(s + 4)
11s - 44 = 7s + 28
11s - 7s = 44 + 28
4s = 72
s = 72/4
s = 18
