X= -a/f = z/mf + g/mf
-a is over f
+ z over mf
+ g over mf
Answer: mean=26 , median=24
Step-by-step explanation:
Mean=Sum of all values/number of values
mean= 30+39+24+ 19+18/5
= 130/5
mean=26
Median
arrange data in order
18,19,24,20,39
In the case of ungrouped odd-numbered data, the number that divided data into 2 equal parts is called the median.
so median=24

Answer:
L=21.6in and w=13.6
Step-by-step explanation:
If the length is 8 inches longer than its width, we can write the width as "w" and the length as the width w+ 8
Area is (width)(Length) = (width)(width+8)
W
----------
| |
| |
| | L = w+8

-----------
A = (w+8)(w)
A = w2 + 8w = 295.
(Problem states that area is 295 sq in)
Need to solve this quadratic equation
w2 +8y - 295 = 0
Factor:
(w - 13.64) (w + 21.64) = 0
So
w - 13.64 = 0. or. w + 21.64= 0
Solve these and get
w = 13.64. or. w = -21.64
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 13.64 inches
Length = 21.64 inches
Answer:
A zero slope means there is no change in the y -coordinates as the x -coordinates change, so this is a horizontal line.
