Its intersection would be at the centre of the sphere, each line being perpendicular to the other, probably
Answer:
51
Step-by-step explanation:
450 < 10x - 1x
450 < 9x
50 < x
you must sell 50 tickets to break even; 51 to make a profit
It would be 550x10 (5 tens = 50)
so you would solve for 550
<u> x10</u>
5500
Answer:
mean = 77
Step-by-step explanation:
We have a confidence interval of (59, 95) with a confidence of 99.7 percent
99.7 is 6 standard deviations from the mean, 3 on each side of the mean
mean - 3 sigma = 59
mean + 3 sigma = 95
We can use elimination to eliminate sigma. Add these equations together
mean - 3 sigma = 59
mean + 3 sigma = 95
---------------------------------
2 * mean = 154
Divide each side by 2
2 * mean/2 = 154/2
mean = 77
