Step-by-step explanation:
Total number of people = 60
Ratio of men to women = 1:2
Total ratio of men to women or Total parts = 1 + 2 = 3 parts
Number of men = 1/3 × 60
Number of men = 20 men
Given number of men who passed = 17 men
Therefore number of men who failed = 20 - 17
number of men who failed = 3 men
Number of women = 2/3 × 60
Number of women = 40 women
Number of people who failed = 1/5 × 60
Number of people who failed = 12 people
And number of women who failed = 12 - 3
number of women who failed = 9 women
Number of women who passed = 40 - 9
Number of women who passed = 31 women
Function y = 7x + 9 has the greater rate of change with the rate of change equal to 7 compared to other functions.
Given that,
Two functions are given one in the form of an equation i.e.
y = 7x +9
and another function is in tabulated form i.e.
x = 0 5 7
y = 3 18 24
Which function has the greater rate of change is to be determined.
<h3>What are functions?</h3>
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
y = 7x +9
Since the slope of the equation represents the rate of change so slope of the above equation is M1 = 7
Now, the slope of the function given in the table,
M2 = (18 - 3) / (5 - 0)
M2 = 15 / 5
M2 = 3
Hence M2<M1, the rate of change of function y = 7x +9 is more than other functions.
Thus, function y = 7x + 9 has a greater rate of change with the rate of change equal to 7 compared to other functions.
