Answer:
Mean is 8 MAD is 4.29
Step-by-step explanation:
Answer:
x = 2 y= 1
Step-by-step explanation:
Solve the system by elimination by stacking the equations lining up the variables.
x + 3y = 5
-x - y = -3
Next, add each of the like terms.
x + 3y = 5
+ -x - y = -3
-----------------------
0x + 2y = 2
y = 1
Then substitute y = 1 into one of the equations.
x + 3(1) = 5
x + 3 = 5
x = 2
Answer:
25,16,121,49
5 is the sqaure root of 25 4 is the sqaure root of 16 11 is the square root of 121 and 7 is the square root of 49
50,145,20, and 8 do not have square roots.
Let
be the length of one leg, and
be the length of the hypothenuse. Finally, let
be the measure of the angle between them. Then, the following relation holds:

Plugging your values, we have

Solving for x, we have
