Answer:
12
Step-by-step explanation:
The range of a data set is just the difference between the largest and smallest values.
So, let's find the smallest value: it's 39. The largest value is 51.
Their difference is:
51 - 39 = 12
Thus, the answer is 12.

Answer:
Step-by-step explanation:
Use the geometric sequence of numbers 1, 3, 9, 27, � to find the following:
a) What is r, the ratio between 2 consecutive terms?
Answer: r=3
Show work in this space.
r=a2/a1=a3/a2=a4/a3 they all have the same ratio.
r=3/1=9/3=27/3=3
:
b) Using the formula for the nth term of a geometric sequence, what is the 10th term?
Answer: a10=19683
Show work in this space.
an=a1*r^(n-1)
a10=1(3)^(10-1)
Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph
Explanation:
One hiker walks 3.3 mph faster than the other.
Suppose, the speed of the slower hiker is mph.
So, the speed of the faster hiker will be:
Both hikers are walking toward each other and meet in 10 hours.
We know that,
So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours
miles.
Given that, they were 77 miles apart in the beginning. So the equation will be
