Answer:The total probability that a random person has an accident in the given year is
.8×.01+.2×.04=0.016
The portion of that which is explained by careful drivers is .8×.01=.08. Thus the answer is
.8×.01.8×.01+.2×.04=.5
Thus it is equally likely that your accident victim was careful or careless.
Speaking informally, that's because, while it's four times more likely that a randomly selected driver is careful, it is one fourth as likely that a careful driver will have an accident, and the two
Step-by-step explanation:
1/((R2+R1)/(R2*R1))
= 1/(R2+R1) * (R2*R1)/1
So answer 4
3000*.50=1500
1500-3000=1500
1500 is the answer
This is easy to calculate as the line is straight vertical. There are 7 units in between the two end points of the line segment, so dividing this by 2 will give you the units from an end point to the mid point. 7 ÷ 2 = 3.5. Subtracting 3.5 from the higher y-value or adding it to the lower y-value gets you (5, 0.5).
Distance = rate x time
distance = 60 miles per hour x 7 1/2 hours
distance = 450 miles
