- Slope Formula:

So using the slope formula, plug in the two points and solve for it as such:

<u>The slope is -3/7.</u>
0.065 as 0 doesn't count as a significant number
Lets put ti this way:
P[1st serve good & wins point] = 60% * 70% = 42% = A
<span>P[2nd serve good & wins point] = 40% * 76% *57% = 17.328% = B </span>
<span>1. P[win point] = A+B = C = 59.328% <------- </span>
<span>2. P[1st serve good | win point ] = A/C = 42 / 59.328 = 0.707 or 70.7%
Please </span><span>remember that 2nd serve come into use only if 1st serve is not good</span>
8^-5 / 8^-3
= (1/8^5 ) / (1/8^3)
=1/8^2
answer is <span>A. one divided by the quantity eight squared</span>
One revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.), to get 81.68 in.
