Answer:
b-about 5 minutes
Step-by-step explanation:
For an object in uniform circular motion (=moving at constant velocity), the time taken to cover a certain distance is given by:

where
d is the distance covered
v is the speed of the object
In this problem we have:
d = 10 miles is the distance covered by both cars
Car A travels at a speed of

So the time it takes is

Car B travels at a speed of

So the time it takes is

So the difference in time is

So, the closest answer is
b-about 5 minutes
Answer:
Step-by-step explanation:
245000 last year
This year 25235
(y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
(( £25.235 - £24.500) / £24.500) * 100 = 0 %
There ain't no percentage change as there needs to be a bigger difference between the two numbers plus u should use the formula
Answer:
0.8753
Step-by-step explanation:
Calculate the probability that your job will be ready before 10.01 am
Here, the parameter of an Exponential is E(X)=12
Now, to calculate the third job probability, it follows Poisson Distribution with parameter 1/λ
Therefore, E(Y) =1/12
Here, The third job will be ready for 10:01 AM, then E(Y)=61/12
Therefore, the required probability is

=1- POISSON(3,5,true)
=1-0.1246
=0.8753
