Answer:
Recursive formula is:
Explicit formula is:
Step-by-step explanation:
We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27
In the given sequence First term a₁= -1
Common difference d = 7
Finding Recursive Formula
The recursive formula is of type: and
Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula for given arithmetic sequence will be:
Finding Explicit Formula
The explicit formula is of type:
We have
First term a₁= -1
Common difference d = 7
So, explicit formula will be:
So, explicit formula is:
Answer:
27 men had a pulse rate between 56 & 100.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 36
Five number summary:
Lowest value: 56
Lower Quartile: 71
Median: 80
Upper Quartile: 100
Highest value: 140
We have to find the number of men that had a pulse rate between 56 & 100.
56 is the lowest value of data and 100 is the third quartile of data.
Now, the third quartile give 75 percentile of data, thus, 75% of data lies between lowest value and the third quartile.
Thus, 75% of men have a pulse rate between 56 & 100.
Number of men that had a pulse rate between 56 & 100 =
Thus, 27 men had a pulse rate between 56 & 100.
