THE ANSWER IS 1 23/100
(there is a space between the one and 23)
Answer:
The first quartile is 5
The third is 8
The interquartile is the difference between the first and third quartile.
The interquartile is 3
Step-by-step explanation:
First, make a list of all the numbers. To find the first quartile, you have to first find the median. The median is the first 7 in the list.
Everything before 7 is the lower percentile of the range.
The firsr quartile is the median of the lower percentile.
The lower list is:
2,3,4,4,5,6,6,6
The median of this list is 5.
The process for finding the third quartile is the same except the list is the higher percentile which is the list of numbers above the median.
You need to find the number of books per days, so start out with 6/8. The 6 represents the bookcases and the 8 is the # of days. 6/8=3/4
Answer: 3/4 bookcases per day. (I hope that's right!)
Answer:
(i) F = 25 N
(ii) F = 35.36 N
(iii) F = 43.3 N
Step-by-step explanation:
We note that the component of force acting along the incline surface is given by the relation
Force, acting parallel to the incline plane, 
= M×g×sin(θ)
Given that the weight of the body is given as 50 N, we have;
M×g = 50 N
Therefore we have;
(i) For the plane with angle of elevation = 30°
= M×g×sin(θ) = 50 × sin(30°) = 25 N
The force = F = 25 N
F = 25 N
(ii) For the plane with angle of elevation = 45°
= M×g×sin(θ) = 50 × sin(45°) = 50 × (√2)/2 = 25·√2 N
= F = 25×√2 N = 35.36 N
F = 35.36 N
(iii) For the plane with angle of elevation = 60°
= M×g×sin(θ) = 50 × sin(60°) = 50 × (√3)/2 = 25·√3 N
= F = 25×√3 N = 43.3 N
F = 43.3 N.
