R= 61 mph
Answer:
52(9/7)^t/1.5
Step-by-step explanation:
The function N(t) a which models the number of branches t years after Aleksandra began studying her trees ;
Initial number of branches = 52
Increment every 1.5 years = 2/7
N(t) = Initial * (1 + r)^t
t expressed per year = t/1.5
Hence,
N(t) = 52(1 + 2/7)^t/1.5
N(t) = 52(9/7)^t/1.5
Answer:
The solution for this equation is n= -4. I didn't see any other equations listed so i can not help compare each equation but hopefully this helps you :)
Step-by-step explanation:
-5n+31= -14n-5
**add 14
9n+31= -5
** subtract 31
9n= -36
** divide 9
n= -36/9
n= -4
Answer:
The difference between the smallest and largest values in the tutored students’ data was 10 students.
Step-by-step explanation:
We are given that a tutor kept track of how many students she had helped every week for a year. The range of the number of tutored students was 10 students.
As we know that the range tells us the difference between the highest and the lowest value in our data set.
In this question, it is stated that a tutor helps a certain number of students every week in a year. So, there must be a week in which she helps the maximum number of students and there must be a week in which she helps the minimum number of students.
Range = Highest value - Lowest value
Hence, the difference between the smallest and largest values in the tutored students’ data was 10 students. This is the best interpretation of this value.
