Contestants A, B, C, D, E, F, and G are in a 10K race. How many different ways can a race with 7 runners be completed? (Assume there is no tie.)
In how many ways can E finish first and A finish second?
What is the probability that E finishes first and A finishes second?
Enter a reduced fraction or decimal.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

you can use a^2+ b^2=c^2
