Answer:

Step-by-step explanation:
Let
x----> the temperature in degrees Fahrenheit
y ---->insect chirping rate in times per minute
we have the ordered pairs
(82,61) and (91,124)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
step 2
Find the equation of the line
we know that
The equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
---> the units are chirps per minute/degree F
take the point (82,61)
substitute and solve for b



substitute

Answer:
-1/-6
Step-by-step explanation:
1/6 is equivalent to-1/-6
The number of ways to choose the colors is 36
<h3>How to determine the number of ways?</h3>
The given parameters are:
Colors = 9
Colors to choose = 7
Since order does not matter, then it is combination
This is calculated using:

This gives

Evaluate

Hence, the number of ways is 36
