Given:
The length between points on a map is 6 inches, 8 inches, and 9 inches.
The scale is one inch equals 5 miles.
To find:
The distances in miles.
Solution:
The given scale is:
1 inch = 5 miles
Using this scale, we get
6 inches = 6 × 5 miles
= 30 miles
8 inches = 8 × 5 miles
= 40 miles
9 inches = 9 × 5 miles
= 45 miles
The distance is miles are 30, 40, 45 miles.
Therefore, the correct option is C.
1. Add the total ages up and divide that by the number of volunteers, that gives you 130 as the total ages added up and 10 volunteers, which gives you a mean of 13,
2. When the numbers are put in an ascending order 12 and 13 appear to be the middle two, therefore divide the sum of the two to find the median, which is 12.5.
Answer:the nth term of the sequence, Tn= -3n +12
Step-by-step explanation:
The nth term of an arithmetic progression is given as
Tn= a+ (n-1) d
where a= first term
and d = common difference
In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that the number is decreasing by 3
The first term, a= 9
and common difference, d = -3
using our formulae
Tn= a+ (n-1) d
Tn= 9 + ( n-1) -3
Tn=9- 3n+ 3
Tn= -3n +12
