Step-by-step explanation:

-x + 7y = 49

convert to slope-intercept form

7y = x + 49

y = x/7 +49/7

y = x/7 + 7

m = x/7

Perpendicular lines have opposite-reciprocal slopes

y = -7/x + b

sub (5,3)

3 = -7/(5) + b

b= 3 + (7/5)

b = 22/5

final answer: y = -7/x + 22/5

Answer:

0.5398

Step-by-step explanation:

Given that :

Total possible numbers vice presidents invited = 7

Required number of vice presidents invited = 1

Probability that a certain vice president is invited ;

P(a certain V. P is invited) = required outcome / Total possible outcomes

P(a certain V. P is invited) = 1/ 7

P(1 of the V. P's hasn't been invited to attend any of the last 4 games)

Then ; it means any of the remaining (7 - 1) = 6 has been invited ;

Hence,

P(1 of the V. P's hasn't been invited to attend any of the last 4 games) = ((7-1) / 7)^4

Likelihood that it could be due to chance :

(6/7)^4 = 0.5397750

= 0.5398
