The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.
Answer:
40m^2 based on what you've given. provide more information if this answer is wrong
Neither parallel nor perpendicular
Hope this helps! :D
we are given
Firstly , we will multiply both sides by 5
now, we can simplify it
now, we can solve for n

Answer:
...
Step-by-step explanation:
7x - 2 +5x - 10 +4x = 180
16x - 12 = 180
16x = 168
x = 10.5
now plug it in
7(10.5) - 2 = 71.5°
4(10.5) = 42°
5(10.5) -10 = 42.5°
