Option 2 Andrew and Jason rode bikes to the park after Andrew finished his morning chores
The mean time it takes to walk to the bus stop is 8 minutes (with a standard deviation of 2 minutes) and the mean time it takes for the bus to get to school is 20 minutes (with a standard deviation of 4 minutes). The distributions are normal.
a. How long will it take (in minutes), on average, to get to school?
b. What is the standard deviation of the trip to school?
c. What is the probability that it will take longer than 30 minutes to get to school?
Due to a miscalculation, you realize it actually takes an average of 10 minutes to walk to the bus stop.
d. How long will it take (in minutes), on average, to get to school?
e. What is the standard deviation of the trip to school?
f. What is the probability that it will take longer than 30 minutes to get to school?
The only ones I need help with is C and F. I have the answer for the rest of them. Can someone please help me with parts C and F??
Answer:
There is no n in the equation but i think its supposed to be 0=In19 so your answer is: n= 0
Step-by-step explanation:
You can tell off the bat the answer is 0, this is why:
0=In19
make it into a distributive problem so you can get n away from the rest:
0=n (I19)
divide I19 on both sides of the equation:
0/I19 =n
Anything divided or multiplied by 0 is 0:
0=n
