(0,-8)
Explanation: In y=mx + b, m represents the slope of the line and b represents the y intercept, since b is -8, it will cross the y-axis at (0,-8)

Is there a photo? I know the last option is true but I feel like there should be a photo with this
        
                    
             
        
        
        
Draw a triangle with shortest side on the ground (horiz.).  The length of this side is 80 feet.  Two angles touch the ground:  a right angle, and the 70 degree angle.
 
Then the height of the building is the 2nd shortest side.
The tangent function is the appropriate one to use here:
                       opp          h
tan 70 deg = -------- = ----------
                        adj        80 ft
                                                                h
Since tan 70 deg  = 2.75,          2.75 = -------
                                                              80 ft
so h = building height = (80 ft)(2.75) = 219.8 ft
        
             
        
        
        
The binomial cumulative probability with p=0.5 for 3+ successes is as follows:

for p=0.5 (50% success rate) it becomes:

the probability is 0.65625, or about 66%
