• Is there any exercise for this?
• I'm struggling in reading bar charts 3 and I was wondering if someone could help me understand how to solve finding the range as well as the mid-range. Can someone please help?
• To find the range, subtract the smallest number from the largest number. To find the mid-range, add the smallest number and the biggest number together then divide by 2.
• What is a midterm exam means
• They are exams that you take half way through the year/term, to measure how much you have grown...
• You could estimate too right?
• estimating is when you find an answer close to the real one. so when you estimate the right answer, it would still be estimating.
• UMMM how do u do this i need help!!
• So basically you’re trying to find out who improved the most...
So if someone’s middle term score is more than the final term score then they didnt improve ...they got worse.And this happend for Jeff and Marta... Somthe people who did improve are:
Jasmine
Nevin
Alejandra
But the question isnt who improved,Its who improved the most
So you have you have to find out *how much they improved *
Jasmine went from 73 to 78
Nevin went from 83 to 88
Alejandra went from 82 to 95
And if you want to find who improved most you have to see who had the biggest difference because the person who improved the most is not the person with the most .....
So these are the difference
Jasmine:5
Nevin:5
Alejandra:13
so therefore Alejandra is the the most improved
I really hope this helped
(it took me forever to write it)
• Is this a exercise for our brain...😁😁
• Khan Academy is meant to exercise our brains! Keep going; you’ll get stronger!
• I wonder why coordinate graphs arnt 3D?
• They can be! Right now you're just working on how to use a 2D or two-dimensional graph with only two planes (x and y), but if you added a third plane (say "z") you could plot coordinates in 3D! In this situation, you would have three numbers for each point on the graph instead of two like this (0, 1, 6).
• How do you find the mean?
