Answer:
y = -1/3 x + 1/3
Step-by-step explanation:
The red line passes through points (0, 2) and (2, 8).
The slope of the red line is (8 - 2)/(2 - 0) = 6/2 = 3
The slope of the perpendicular line is -1/3, and it passes through point (1, 0).
y = mx + b
y = -1/3 x + b
0 = (-1/3)(1) + b
b = 1/3
y = -1/3 x + 1/3
So it took an hour an 15 minutes which means the distance traveled is their speed+1/4 of their speed, also any answers that have northbound going faster than 6km/h above south is not right so B and D seems to be out of the picture
Answer:
mean=14, variance=9.1
Step-by-step explanation:
for binomial distribution
n=number of outcomes
p=probability of succcess
q=probability of faliure
p+q=1
any probability given is always 'p'
mean=np
n=40
p=0.35
mean=40*0.35
mean=14
variance=npq
p+q=1
q=1-p
q=1-0.35
q=0.65
variance=40*0.35*0.65
variance=9.1
In order from top to bottom the answers are a,d,c,d
I hope this helped!
