What would you have to do to make the line y = 2x -7 steeper on the coordinate plane?
ValentinkaMS [17]
The slope, if increased, would make the line y=2x-7 steeper. If you were to increase the y intercept, you would just move the line, not tilt it. Suggest changing it to 4x-7 = y or 8x-7= y, if you increase the slope, it'll make it steeper.

Given that Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22.

Prob for  a random person booked arrive for flight = 0.86

No of persons who books and arrive for flight, X is binomial, since there are two outcomes and each person is independent of the other

The probability that if Air-USA books 24 persons, not enough seats will be available

= P(X=23)+P(x=24)

= 0.1315

B. no, it is not low enough

-------------------------------

The prob we got is >10% also

Step-by-step explanation:

The general equation for a circle is

{(x - a) }^{2}  + {(y - b) }^{2}  =  {r}^{2}

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
