Answer:
On the graphing calculator, use the function normCdf, where
- lower bound = -9999
- upper bound = 210
- mean = 250
- standard deviation = 46
It will result in normCdf(-9999,210,250,46) ≈ 0.192269 or 19.2269%
We have an equation: ?/350= 72/100
Cross multiply:
100*?= 72*350
⇒ ?= 72*350/100= 252
72% of 350 friends is 252 friends~
Here you go I hope I helped
Answer: it’s not an even number it 6.6 repeating so if round up and say 7 bags
Step-by-step explanation:
THis is a cool question.
1) Use the point slope form to find the equation of the lines between two of the points (choose two points that when a line is drawn between them make a chord on the circle).
2) Use the midpoint of a line equation to find the midpoint of the line, then find the slope of the line that is perpendicular at that point and write an equation for it.
3) Then do the same thing for the other two points that form a chord on the circle.
4) Then set the two equations equal to each other and solve. The point where they meet is the circumcenter.
