Answer:
Mode = 19.
Median = 23.
Step-by-step explanation:
Arrange in ascending order:
8 9 12 15 17 18 19 19 20 22 24 25 26 27 28 31 34 36 40 43
The modal amount is the one which occurs most , which is 19.
The median is the middle value of the 20 amounts.
As there is an even number of amounts the median is the mean of the 2 middle numbers:
Median = (22 + 24) / 2
= 23.

(5,0)
Step-by-step explanation:
5 is in x-axis and y is in y-axis
Answer:
its ok
Step-by-step explanation:
there is this app called photo math where you take a picture of the problem and its answers you but the answer is -4g
Let the width be : x
length : (2x - 6)
(2x - 6) (x) = 2x square - 6x
2x square - 6x = 140
2x square - 6x - 140 = 0
if you use the cross method or calculator you’ll get :
( x - 10 ) ( x + 7) = 0
x = 10 or x = -7 ( reject because negative )
so we use x = 10.
width = 10
length = 2(10) - 6 = 14
Number of 1/2-inch cubes length-wise = 8 1/2 ÷ 1/2 = 17
Number of 1/2-inch cubes width-wise = 5 1/2 ÷ 1/2 = 11
Number of 1/2-inch cubes height-wise = 2 1/2 ÷ 1/2 = 5
Number of 1/2-inch cubes = 17 x 11 x 5 = 935
------------------------------------------------------------
Answer: 935 1/2-inch cubes are needed.
