Answer:
38.11 and 3.66
Step-by-step explanation:
The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively.
What is the mean absolute deviation?The average distance between an observation's mean and its variance is shown by the mean absolute deviation, a measure of variability. mean makes understanding simpler by using the data's original units. A wider deviation from the average is reflected by larger values. The mean absolute deviation is sometimes referred to as the average absolute deviation and the mean deviation.
The mean is the average of the data set and given by
Mean = sum of all the data sets/number of data set
Mean = (33 + 34 + 42 + 36 + 39 + 36 + 39 + 40 + 44)/9
Mean = 38.11
Now standard deviation is given by
[tex]s = \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2}[/tex]
Where N is the number of data while the x bar is the mean.
So by using the formula,
Standard deviation = 3.66.
Hence "The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively".

3. Mr. Matho has a garden in the shape of an equilateral triangle, He has planted a tree in each corner
of his garden; an oak tree, a maple tree, and a pine tree. In order to water his garden, he decides
that the best place to put a sprinkler would be in the middle of the garden, so it would be equidistant
from all three trees. If the perimeter of his garden is 36 m and the sprinkler is 2-3 m from the
fence joining the oak and maple tree, how far away is the sprinkler from any one of the trees?
Answers
Answer:
The distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.
Step-by-step explanation:
Since the perimeter of the triangle P = a + b + c where a, b and c are the length of sides. Since the triangle is an equilateral triangle, a = b = c. So,
P = 3a
a = P/3
Since the perimeter = 36 m,
a = 36 m/3 = 12 m.
Since the sprinkler is 2 m from the fence joining the oak tree and maple tree, thee line perpendicular from the sprinkler to the fence is thus 2 m. This line cuts the side at the midpoint of the fence which is 12 m/2 = 6 m.
Since this is now a right-angled triangle, we now use Pythagoras' theorem to find the distance from the sprinkler to each tree which is
L = √[(2 m)² + (6 m)²]
= √[ 4 m² + 36 m²}
= √40 m²
= 2√10 m
= 6.32 m
If the fence is 3 m from the sprinkler, the distance
L = √[(3 m)² + (6 m)²]
= √[ 9 m² + 36 m²}
= √45 m²
= 3√5 m
= 6.71 m
So, the distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.

Step-by-step explanation:
Add the first two then subtract
The answer to the equation is B, [tex]-\frac{2}{3}[/tex]
First, you must add the the fractions. You add the numerator because all three fractions have like denominators.
[tex]-\frac{8}{9} +\frac{4}{9} -\frac{2}{9}=\frac{6}{9}[/tex]
Then, you must simplify [tex]-\frac{6}{9}[/tex]
[tex]-\frac{6}{9} =-\frac{2}{3}[/tex]

Describe a sequence of transformations that take isosceles trapezoid T to its image T'
Answers
Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above
Step-by-step explanation:
Transformation involves changing the position of a shape
The transformation from T to T' is a 90 degree counterclockwise
From the figure, we can see that:
The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of TThis means that:
A 90 degree counterclockwise through point D will take trapezoid T to T'
Hence, the required transformation is a 90 degree counterclockwise through point D

How do you write 2x^5-9x^4-2x^2+10 in standard form?
Answers
Answer:
[tex]2x^5-9x^4+0x^3-2x^2+0x+10[/tex]
Step-by-step explanation:
A polynomial is in standard form when its terms are ordered from highest to lowest degree.
If the polynomial is missing terms, it must be completed by setting their coefficients to 0.
The given polynomial is:
[tex]2x^5-9x^4-2x^2+10[/tex]
The terms are ordered, but it's incomplete. The terms with exponent 3 and 1 must be included with zero coefficient.
Thus the polynomial in standard form is:
[tex]\boxed{2x^5-9x^4+0x^3-2x^2+0x+10}[/tex]
(60)x = 1, what are the possible values of x? Explain your answer.
Answers
Answer:
[tex]\frac{1}{60}[/tex]
Step-by-step explanation:
Problem:
The possible values of x in the equation (60)x = 1;
Solution:
Such a problem like this in which the highest power of the unknown is 1 will have just one solution.
60x = 1
To solve this, we take the multiplicative inverse of 60;
the multiplicative inverse of 60 = [tex]\frac{1}{60}[/tex]
Use this inverse to multiply both sides of the expression;
[tex]\frac{1}{60}[/tex] [tex]x[/tex] 60x = 1 x [tex]\frac{1}{60}[/tex]
x = [tex]\frac{1}{60}[/tex]

what is the difference between the mean and the median of the set ( 3 ,8 ,10 ,15)
Answers
Answer:
You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example, you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.
Step-by-step explanation:
Mean) 3+8+10+15=36, 36/4=9 ANSWER=9
Median) 8+10=18, 18/2=9 ANSWER=9
In the case, the mean and median are the same and depending on context you could choose either method. It also helps that there is no outlyer. If there were on I would recomend finding the median.
