The point (4,y) has a known x coordinate of x = 4. The y coordinate is unknown right now so we'll just call it y.
Draw a vertical line (see side note below) through 4 on the x axis. I've done so in red (see attached image). The red line crosses the graph at the point (4,1) so this tells us that
y = 1Answer: y = 1
Side Note: you don't have to draw a vertical red line but it's handy to see how it works out. After you get used to these types of problems, you can visually be able to see the answer without these extra lines.
22 (what number is in the middle one you put it in ascending order)
18 (the first quartile is the first quarter of the sorted list)
23 (the third quarter, the number in between the last number and the median)
5 (the range between quartile 1 and quartile 3)
Have a great day <3
So you have to find 15 percent of 900 which would be 135
I don't know about the first one but the second one is 34.9°. It would be that because are right angles add up to 90° and if you subract 55.1 and 90 it would equal 34.9. But this rule only works on right angles.
