7 x 500,000 = 3,500,000.
The towns are 3,500,000 units apart (I don't know what the cm were scale too, sorry.)
Answer:
i believe a quadratic function
Step-by-step explanation:
quadratics are when an equation is x^2 so yeah (sorry if thats not what it's asking)
Y= 0.26x+4.4*10^-4
Y= 0.26x+4.4*10,000
Y=0.26x+44,000
I'm not sure if you were only trying to simplify the problem, but I hope this helped
Simply cross-multiply about,
Answer: see below
Step-by-step explanation:
(i)
200/2 = 100
Find 100 on cumulative frequency and the correspinding time: 14 minutes. So the answer is 14 minutes.
(ii)
First, find the lower quartile —> 200/4 = 50
Upper quartile —> 200/(3/4) = 150
Find the difference: 150 - 50 = 100
So the interquartile range is 100
