Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
...(i)
Where, a is the initial value and
is the decay factor and
is the growth factor.
The exponential function passes through the point (0,6). Substituting
in (i), we get



The exponential function passes through the point (1,2). Substituting
in (i), we get




Here,
lies between 0 and 1. Therefore, the decay factor of the given exponential function is
.
Hence, the correct option is A.

Answer:
The weighted mean grade is 78.62
Step-by-step explanation:
We are given the following in the question:
Regular exam score = 79, 74, and 73
Weightage of regular exam = 12%
Final exam grade = 66
Weightage of final exams = 17%
Course project grade = 88
Weightage of project = 10%
Homework grade = 93
Weightage of homework = 37%
Mean of regular exam scores =

Weighted mean grade


The weighted mean grade is 78.62
