Answer:
mean=28.8
median=31
Step-by-step explanation:
mean=sum of all values/number of all values
mean=40+45+7+21+31+40+45+7+21+31/10
=288/10
mean=28.8
Median
arrrange in order
7,7,21,21,31,31,40,40,45,45
in case of even ungrouped data median is the average of middle two values
= (31+31)/2
median =31
Answer:
Simplify each term.
Px+px+3p=10x−7
Move all terms not containing P to the right side of the equation.
Px=10x−7−px−3p
Divide each term by x and simplify.
P=10−7/x−p−3p/x
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Since X is (7,11) and X' is (5,11) we are basically translating it 2 units to the left.
Do the same for Z.
Z's x coordinate is 8 and moving it to the left makes the x coordinate 6.
The y coordinate stays the same the Z' coordinates are (6,7).
The formula of an area of a triangle:
b - base
h - height
We have
b = 12 in
h = 7 in
Therefore correct answer has Hazel.
Emmitt wrong described the base of the triangle.
