The answer to this question is and always will be 0.
Law of cosines:
b^2 = a^2+c^2 -2*a*c*cos(B)
b^2 = 400^2 + 240^2 - 2*400*240*cos(16)
b^2 = 217600 - 184562.25
b^2 = 33037.75
b = sqrt(33037.75)
b = 181.76 = 181.8 yds.
The answer is D.
Answer:
Slope is 9 and -2 is the y-intercept
Step-by-step explanation:
As an equation in slope-intercept form is written as y=mx+b where m is slope and b is its intercept on the y-axis.
If one writes a linear equation as a function of y, one can easily get slope which is coefficient of x and intercept, which is constant term.
As y= -9x is already in this form, we have its slope as -9 and intercept on y-axis is 0, that is if it passes through the line of origin.

First problem:
Find the z score for raw score 6 minutes:
6 - 5
z = --------- = 1.429
0.7
Using a TI-83 calculator's distribution functions, I found that the area to the right of 6 minutes is
normalcdf(1.428,100) = 0.076
