3 is the bottom length of the triangle and its the same for both sides so that leaves us with the square in the middle, since the bottom of the triangle is 3 and the top of the trapezoid is 10 we subtract 3 from 10 and get 7 and since a square has all identical sides we know the area of the square is 7 x 7 = 49 + 48 (which is the two triangles) = 97

If the mean of the data set is 3.533. Then the mean absolute deviation for the data set will be 1.831.
How do find the mean absolute deviation of discrete data?Suppose the data specified is of n sized as
[tex]\rm x_1, x_2, \cdots , x_n[/tex]
Let this data's mean will be μ
Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.
It is calculated as:
[tex]\rm M.A.D = \dfrac{\sum_{i=1}^n|x_i - \mu|}{n}[/tex]
The data set is given below.
3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6
Then the mean of the data will be
Mean = (3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6)/15
Mean = 53/15
Mean = 3.533
Then the mean absolute deviation for the data set will be
[tex]\rm M.A.D = \dfrac{|3-3.533| + |5-3.533| + |6 - 3.533| + |3 - 3.533| + ...+|6-3.533|}{15}[/tex]

The temperature dropped 2 °F every hour for 12 hours. What was the total number of degrees the temperature changed in the 12 hours?
24 degrees
14 degrees
-24 degrees
-2 degrees
Answers
Answer:
-24 degrees
Step-by-step explanation:
To find the total change in temperature, multiply 12 by -2, since it dropped 2 degrees each hour for 12 hours.
12*(-2)
= -24
This means -24°F was the total number of degrees the temperature dropped.
Answer:
The question mentions the keyword, "temperature drops" meaning we need to alternatively subtract.
[tex]t = -2 * 12[/tex]
If we know that positive 2 times 12 is 24, we know -2 times 12 will be negative 24°, because any negative number times a positive number is always a negative number.

Will give brainiest!!! Rose has no more than $65 to spend on girl scout cookies. She has already spent $38.50 on samoas; if thin mints cost $4 each, how many boxes of thin mints can Rose afford? 65.00 Is the answer 6 cuz that's what I got?
Answers
Answer:
6
Step-by-step explanation:
so if she has $65 and she spent 38.50 you find the difference which is $26.50 then you divide it by 4 which is 6.62 so yes your right its 6 if you round it
Answer:
6 boxes.
Step-by-step explanation:
65 ≥ 38.50 + 4x where x is the number of boxes of mints.
65 - 38.50 ≥ 4x
(65-38.40/ 4 ≥ x
x ≤ 6.625
so the answer is 6 boxes.

Step-by-step explanation:
60/4 which is the chance it gets out of being drawn
Using the concept of probability, the reasonable prediction for the number of times a purple marble will be drawn is 12 times (option A).
What is a reasonable prediction for the number of times a purple marble will be drawn?To predict the number of times a purple marble will be drawn, we can use the concept of probability. The probability of drawing a purple marble in a single draw is the number of purple marbles (4) divided by the total number of marbles (5 + 6 + 3 + 2 + 4 = 20).
Probability of drawing a purple marble = 4 / 20 = 1/5
Since the student makes a total of 60 draws and each draw is independent (the marble is returned to the bag after each draw), we can use the concept of expected value to predict the number of times a purple marble will be drawn.
Expected value = Total number of draws × Probability of drawing a purple marble
Expected number of times a purple marble will be drawn = 60 × (1/5) = 12

The bar graph shows the results of spinning a spinner 100 times. Use the bar graph to find the experimental probability of not spinning a 5.
PLEASE QUICK
Answers
Answer:
81%
Step-by-step explanation:
1.
We know that the probability of spinning a five is 19% since:
19/100 = 0.19 = 19%
However, we are looking for the probability of NOT spinning a five. So, we will have to find the probability sum of the remaining numbers (1, 2, 3 and 4).
2.
- The probability of spinning a one is 20% since:
20/100 = 0.2 = 20%
- The probability of spinning a two is 18% since:
18/100 = 0.18 = 18%
- The probability of spinning a three is 22% since:
22/100 = 0.22 = 22%
- The probability of spinning a four is 21% since:
21/100 = 0.21 = 21%
3.
Now we will add all of these probabilities together to find the total probability of NOT spinning a five!
20% + 18% + 22% + 21% = 81%
Therefore, the probability of not spinning a five is 81%.
(While writing all of this down, I realized it was completely unnecessary)
Basically, the total probability of all of these numbers is equal to 100%. The probability of spinning a five is 19% as we inquired above. Therefore, all we need to do is subtract 19% from 100%!
100% - 19% = 81%

Heres another brainly question giving 20pts!!
Answers
Answer:
We are given an area and three different widths and we need to determine the corresponding length and perimeter.
The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards. This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.
The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards. This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.
The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10. This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.
Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.
Hope this helps!
