Answer:
77.7 miles.
Step-by-step explanation:
We have been given that Louis has already biked 17.7 miles this week. He can bike 6 miles in one hour. Let the total biked be represented by d and let the number of hours biking be represented by h. an equation that represents this scenario is: .
To find total number of miles Louis biked in 10 hours we will substitute 10 in place of h in our given equation.
Therefore, number of total miles biked will be 77.7 miles if Louis bikes for 10 hours.

Answer:
Step-by-step explanation:
∵ When x is a random variable having distribution B(n, p), then for sufficiently large value of n, the following random variable has a standard normal distribution,
Where,
Here the variable X has a binomial distribution,
Such that, np (1 - p) ≥ 10 ⇒ n is sufficiently large.
Where, n is the total numbers of trials, p is success in each trials,
So, the mean of variable X is,
And, variance of variable X is,
