Answer:
y = x - 7
Step-by-step explanation:
x - y - 1 = 0
y = x - 1 .... y = mx + b
m = 1 parallel line has same slope
for (2, -5) m = 1 b = y - mx = -5 - 1x2 = - 7
equation: y = x - 7
Answer:
Step-by-step explanation:
If, collectively, 15 people weigh more than 3500 pounds, that means each person must weigh more than 3500/15 = 233.33 pounds.
If the distribution for population weights is normal at mean = 180 and standard deviation = 25 lbs, that means the probability for 1 person to weigh higher than 233 lbs is
For all 15 people to have higher weigh than that then the probability is
This is indeed very unlikely to happen
