Answer:
Angles are
Step-by-step explanation:
Sum of interior angles of triangle is
The ratio of the measures of the three angles of a triangle is
Hence the angles can be
We have
Angles are

Step-by-step explanation:
12-(-7)= 19
(12+7=19)
Answer:
8, 10, 15, 16, 17, 17, 22
16 is the median
Step-by-step explanation:
Answer:
Part 1) The rate of change is
Part 2) The initial value is 68
Part 3) The function rule to the linear model is
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
step 1
Find the slope
take two points from the table
(0,68) and (15,85)
The formula to calculate the slope between two points is equal to
substitute the values
In a linear function , the slope is the same that the rate of change
therefore
The rate of change is
step 2
Find the y-intercept
we know that
The y-intercept is the value of y when the value of x is equal to zero
Looking at the table
For x=0, y=68
therefore
The y-intercept is
The y-intercept is also called the initial value
therefore
The initial value is 68
step 3
Determine the function rule to the linear model
we have
substitute
