The probability of Erin not having a heart attack according to her family history would be 30%.
The probability of the test predicting correctly is 67%.
Therefore, the probability of the test correctly predicting that Erin will not have a heart attack would be (0.30)(0.67) = 0.201 or 20.1%.
        
                    
             
        
        
        
Answer:
f(t) = $67000(.30)^t          (Must use " ^ " to indicate exponentiation)
Step-by-step explanation:
This is an exponential function:
f(t) = $67000(.30)^t  (Must use " ^ " to indicate exponentiation)
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The functions are written in slope-intercept form. 
The graph crosses the y-axis at (0,-2), so the y-intercept is -2.
You can eliminate D because its y-intercept is +2, not -2.
(1,1) and (0,-2) are points on the line.
The slope of the line is (-2-1)/(0-1) = 3
You can eliminate B because its slope is ⅓.
Eliminate C because its slope is -3, not 3.
Answer B
