Answer:
Annie walked 1 11/12 miles
Step-by-step explanation:
Trail= 4 1/2 miles
Annie ran the first 2/3 miles
Remaining miles= Total miles - Miles covered first
= 4 1/2 - 2/3
= 9/2 - 2/3
= 27-4 / 6
= 23/6 miles
Remaining miles = 23/6 miles
Annie walked for 1/2 of the remaining distance
1/2 of the remaining miles= 1/2 × 23/6
=23 / 12
= 1 11/12
Annie walked 1 11/12 miles
Answer:
Since n(1-p) < 10, it is not suitable to use a normal distribution.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 10
n(1-p) >= 10
In this question, we have that:
n = 17, p = 0.8. So
np = 17*0.8 = 13.6 -> Ok
n(1-p) = 17*0.2 = 3.4 -> No
So, since n(1-p) < 10, it is not suitable to use a normal distribution.
