Given:
speed = distance / time

walking: 3 miles per hour
running 5 miles per hour
for a total of 3 hours.

3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8 

7/8 * 60 mins = 52.50 minutes

t = 1 hour and 52.5 minutes

It took Stu 1 hour and 52.5 minutes to hike the trail one way.

Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts early and is alread
BARSIC [14]

Answer:

The word per indicates the slope (m) of a linear function, y=mx +b.Using d for x and p for y , the equation representing Ashely's reading is p = 10d. Carly begins on page  40 which represents b, the y intercept of a linear function which indicates an initial amount.  So the equation representing Carly's reading is p=8d + 40.

Assume that you have a binomial experiment with p=0.4 and a sample size of 100. the expected value for this binomial distributio
UkoKoshka [18]
In Binomial distribution, the expected value or mean is given by,
E(X) = np 
where, p = probability of success and n=number of sample size.

E(X) = 100×0.4 = 40
