2.26 is the Mean Absolute Deviation. This is found by finding the arithmetic mean of the dataset and finding the difference between each value and the arithmetic mean, these differences are then averaged to find the MAD.

Subtract. Express your answer in simplest terms. 3/4 - 3/5

bazaltina [42]

3/4 - 3/5

common denominator is 20

15/20 - 12/20 = 3/20

3/20 is your answer

multiply the opposite denominator with current numerator to get your new numerator number

hope this helps

What is the solution to the system of linear equations below? - 2x + 5y 30

avanturin [10]

Answer: Infinite solutions

Step 1: Turn this into y=Mx+b form

The current equation is—

-2x+5y=30

Since we want to get y alone on the left side, let’s add 2x on both sides

-2x+5y=30
+2x +2x
____________
5y=2x+30

Step 2: Again, trying to get y alone, we need to divide 5 on both sides

5y=2x+30
/5 /5 /5
________
y=2/5x+6

Step 3: Now that we know how to find y, substitute that in where y is in the equation

-2x + 5(2/5x+6) = 30
-2x + 2x + 30 = 30
30=30

Seeing that you cannot get a specific answer for y when solving, there is an infinite number of solutions

Hope this is right and it helps comment below for more questions :)

What is the length of LINE GH? And please explain why thank you:

lesya692 [45]

co-ordinates of point G are (1,2)

co-ordinates of point H are (3,-3)

so, by distance formula :

$\sqrt{( {x1 - x1})^{2} + ( {y1 - y2})^{2} } \\ = \sqrt{( {1- 3})^{2} + ( {2 - ( - 3)})^{2} } \\ \sqrt{( { - 2})^{2} + ( {2 + 3})^{2} } \\ \sqrt{( { - 2})^{2} + ( {5})^{2} } \\ \sqrt{4 + 25} \\ \sqrt{29}$

so, it is root(29) or 5.38 units

At certain time of day , a 30 meter high building cast a shadow that is 31 meters long . what is the angle of the elevation of t

Nimfa-mama [501]

Answer:

Option C. 44 degree

Step-by-step explanation:

Let

A-----> the angle of the elevation of the sun

we know that

The tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

In this problem

The opposite side is 30 meters

The adjacent side is 31 meters

$tan(A)=\frac{30}{31}$

$A=arctan(\frac{30}{31})=44\°$
