Write the equation of the line in slope-intercept form that goes through the points: (2, 4) and (7, -1) *
avanturin [10]

Answer:

1. slanting upward because the slope is positive one.

2. A: 3/4     B: 4/-3

3. A: 3        B: y=3x-10

1. (-2-7)/(-4-5) = -9/-9 = 1

2. A: (7-4)/(7-3) = 3/4

  B: (8-0)/(-6-0) = 8/-6 = 4/-3

3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10

Find the probability that when 200 reservations are accepted for united flight 15, there are more passengers than seats availabl
Arlecino [84]

The solution for this problem is:

We know the problem has the following given:

Sample size of 200

X = 182

And the probability of .9005; computation: 1 - .0995 = .9005

 

So in order to get the probability:

P (x >= 182) = 1 – 0.707134 = .292866 is the probability that when 200 reservations 
are recognized, there are more passengers showing up than there 
are seats vacant.

The other solution is:

p (>= 182) = p(183) + P(184) + P(185) + ... + P(199) + P(200) = 0.292866
