What is the exponential regression equation that fits these data?
2 answers:
Answer:
The exponential regression equation that fits the data values is:
Step-by-step explanation:
We are given a table of data value as:
x y
-4 0.025
-3 0.075
-2 0.25
-1 0.70
0 3
1 8
2 20
3 60
4 160
Hence, on plotting these data points we observe that the line of best fit is a exponential curve and the equation that will best fit these data points is:
Hence, option: C is the correct answer.

Given:
Slips of paper numbered 1 to 15 are placed in a box.
To find:
The probability that the number picked is either a multiple of 5 or an odd number.
Solution:
We have,
Total outcomes = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
No. of total outcomes = 15
Multiple of 5 are 5, 10, 15.
Odd numbers are 1, 3, 5, 7, 9, 11, 13, 15.
Number that are either a multiple of 5 or an odd number are 1, 3, 5, 7, 9, 10, 11, 13, 15.
No. of favorable outcomes = 9
We know that,
Therefore, the probability that the number picked is either a multiple of 5 or an odd number is 0.6.
