hope this helps!!!!
<span>So we need to find the value of 8.3*24.2*0.03 and round it to the nearest hundredth. So lets multiply the numbers first: 8.03 * 24.2 * 0.03 = 6.0258 and now we need to round it to the nearest hundreth. The nearest hundreth is .03 and we get: 6.03 so the correct answer is D.</span>
Not sure if you still need this but the answer is 17/19.
Answer:
74.72
Step-by-step explanation:
Given
mean
Standard deviation 
For Top 25%

and Z value for 75 % is 0.6744
Thus score which separates the Top 25% of students is


The slope of the line is the gradient, which you can find through rise over run
m (gradient) = (y1 - y2) / (x1 - x2)
where (x1, y1) is the coordinate of the first point, and (x2, x2) is the coordinate of the second point
in your question:
x1 = -4
x2 = 19
y1 = -13
y2 = 11
m = (-13 -11) / (-4 -19) = -24 / -23 = 24/23 or 1.04 (2d.p.)
hope that helps :)
