X^2 + 4y^2 - 6x = 7
x^2 - 6x + 9 + 4y^2 = 16
(x-3)^2/16 + y^2/4 = 1
The graph is an ellipse
hope this helps
The sum of all interior angles in a polygon, regular or not, is
18(n - 2)
where "n" is how many sides are there in the polygon, now, notice, this polygon has 7 sides, so is a heptagon, so the sum of its interior angles will be 18(7 - 2) or 900.
now, subtract all other angles from 900, and what's leftover is "x".
324904 = 300000 + 20000 + 4000 + 900 + 4
300000 = three hundred thousand
20000 = twenty thousand
4000 = four thousand
900 = nine hundred
4 = four
324904 = three hundred twenty-four thousand, nine hundred and four
Well 1/4 is 0.25
1/4 = 0.25 x 22 = 5.5
So it might be 5.5 pounds of green beans
We need to find the probability of atleast one failure in 5 trails
Probability of success = 30% = 3/10
The opposite meaning of atleast one failure is all success (no failures)
Probability of (atleast one failure ) = 1- Probability ( success)
First we find probability of success
Formula for binomial distribution
All success so n=5, r=5, p= 3/10, q= 1-p = 7/10
Probability (success) =
=
Probability (atleat one failure) = 1 -
= 0.92224
= 92.2%
