Answer:

-3, 8

Step-by-step explanation:

-x² + 5x + 24 = 0

-x² + 8x - 3x + 24 = 0

-x(x - 8) - 3(x - 8) = 0

(-x - 3)(x - 8) = 0

x = -3 , 8

Determine the equation of a line, in slope-intercept form, that passes through the points (9, -2) and (12, 0).
Law Incorporation [45]

As x increases from 9 to 12 (a change of 3), y increases from -2 to 0 (a change of 2).  Thus, the slope of this line is 2/3.

Subbing this info and the coordinates of one of the points into y = mx + b, we get:

-2 = (2/3)(9) + b.  Solving for b:  b = -2 -18/3 = -8.  Then the equation of this line is:

y = (2/3)x - 8.

Check by subst.:  Does (12,0) satisfy this equation?  0 = (2/3)(12) - 8?  Yes.

Use the following table to determine P(X≤3).
DiKsa [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

P(x \leqslant 3) = P(1) + P(2) + P(3) \\

P(x \leqslant 3) = 0.25 + 0.32 + 0.17  \\

P(x \leqslant 3) = 0.74

Thus the correct answer is

the last option .
