Answer:
Parallel
Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Both given equations are in this form, that is
y = x + 1 → m =
y = x - 7 → m =
Parallel lines have equal slopes thus the lines are parallel
Answer:
It's more likely that all of the residents surveyed will have adequate earthquake supplies since it has a probability of 98.02% which is very close to 100%.
Step-by-step explanation:
-This is a binomial probability problem with the function:
-Given p=0.3, n=11, the is calculated as:
Hence, the probability that at least 8 have adequate supplies 0.0043
#The probability that non has adequate supplies is calculated as;
#The probability that all have adequate supplies is calculated as:
Hence, it's more likely that all of the residents surveyed will have adequate earthquake supplies since and that this probability is 0.9802 or 98.02% a figure close to 1
