» Concepts
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex is not I.

Answer:
The mean absolute deviation is 4
Step-by-step explanation:
The mean absolute deviation is a measure of how much a data set varies.
Step 1: Compute the mean
mean = the sum of all the terms / number of terms
mean = 94 + 86 + 95 + 99 + 88 + 90 / 6
= 552 / 6
= 92
The mean is 92
Step 2: Finding the absolute deviation
You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values
|data set #1 - mean| + |data set #2 - mean| + ... + |data set #6 - mean|
= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|
= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|
= 2 + 6 + 3 + 7 + 4 + 2
= 24
To find the mean absolute deviation you divided the sum by total number of terms...
24/6 = 4
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

What is the mean absolute deviation of a data-set?
The mean of a data-set is given by the sum of all observations divided by the number of observations.
The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
The mean absolute deviation represents the average by which the values differ from the mean.

(Find the Probability Question)
Choose 2 girls from a class of 12 boys and 8 girls.
Answers
Step-by-step explanation:
what should be the question ?
how many different pairs of 2 girls can you pick out of 8 ?
what is the probability that a specific girl is in the picked pair ?
or is it : if you pick randomly 2 students from the class, what is the probability to have picked 2 girls ?
and there are more options.
but I assume the problem is the picking randomly 2 students.
so, it is 20 students (12 + 8). if we pick 1 student, we have a chance of 12/20 = 3/5 to pick a boy, and a chance of 8/20 = 2/5 to pick a girl.
in our experiment we pick 2 students in a row without returning the first pick into the main pool.
the probabilty for the first pick to be a girl is, as mentioned, 2/5 or 0.4.
for the second pick we have only 7 out of 19 choices to pick a girl. so, the probability to pick a girl now is 7/19.
the combination of both (non-overlapping) probabilities is done via multiplication, and the probabilty to pick 2 girls is :
2/5 × 7/19 = 2×7 / 5×19 = 14/95 = 0.147368421...

Tamar is thinking of a number in the hundredths. Her number is greater than 0.8 and less than 0.9. The greatest digit in the number is in the hundredths place. What number is Tamar thinking of? Explain.
Answers
Step-by-step explanation:
Let x be the number Tamar is thinking of.
0.8 < x < 0.9
Since the greatest digits in the hundreths is greater digit, and there's an "8" in the tenths, the number can described as:
0.88< x < 0.9
There is only a single number in the hundredths that would fit the expression above, and that is 0.89.
Therefore, Tamar is thinking of the number 0.89.

Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?
A. 144 in
B. 124 in
C. 54 in
D. 48 in
Answers
Answer:
A. 144 in
Step-by-step explanation:
Squares have congruent sides.
One side is 12 inches, so all of the other sides are 12 inches.
To find the area of a square, multiply width by height. The width is 12, and the height is also 12
12 * 12 = 144
144 in ^2
If it is 12 inches, the sides are all 12 inches, so simply multiply the height and width so 12 • 12 = 144
So the area is 144 inches

90 = 2x +x
90 = 3x
90/3= 3x/3
30 = x
Now let’s look back at the angles, the first one is just x, so it would be 30° but the second one is 2x so it would be 30° x 2 which would make it 60°
Hope this helps!
Answer:
x = 30
(2x)° = 60°
x = 30°
Step-by-step explanation:
The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:
2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x
3x = 90
divide both sides by 3 so you can get x by itself
3x divided by 3 = x
90 divided by 3 = 30
you get x = 30
since x = 30, 2x is the same as 2 times 30, and that is 60.
