Answer:
The second one
Step-by-step explanation:
Answer:
A) In 4 hours the tempature would both be the same
B) The tempature then would be 3 degreees Fahrenheit
Step-by-step explanation:
SO for the first step just make a list
In my format
x (hour): Coldspit and Frostberg in temperature
1st hour: -4.5 and 15
2nd hour: -2 and 11
3rd hour: 0.5 and 7
4th hour: 3 and 3
Answer:
0.1587
Step-by-step explanation:
Let X be the commuting time for the student. We know that
. Then, the normal probability density function for the random variable X is given by
. We are seeking the probability P(X>35) because the student leaves home at 8:25 A.M., we want to know the probability that the student will arrive at the college campus later than 9 A.M. and between 8:25 A.M. and 9 A.M. there are 35 minutes of difference. So,
= 0.1587
To find this probability you can use either a table from a book or a programming language. We have used the R statistical programming language an the instruction pnorm(35, mean = 30, sd = 5, lower.tail = F)
There needs to be values to answer the question.
