about
y = 0 + 3.2t
Part a:
Identify the y-intercept of the regression line and explain what it represents in the context of the data.
Answer:
The y-intercept is zero and it means that in the year 1993 there was no change in the seawater level.
Step-by-step explanation:
See the scatter plot graph attached.
It represents the change in global sea level from 1993-2017, according to the National Aeronautics and Space Administration (NASA).
The equation of the regression line is written below, where Y represents the predicted change in sea level in mm and t represents the years since 1993.
y = 0 + 3.2t .............. (1)
Therefore, the equation is in the slope-intercept form and the y-intercept is zero for this graph.
That means in the year 1993 there was no change in the seawater level. (Answer)
, what would you expect the values of
to be, assuming that 3 is part of the domain of f(x)? Explain your answer.
Answer:
3
Step-by-step explanation:
if we combine a function f(x) and its inverse f-¹(x), the result will be x
f-¹(f(x)) = f(f-¹(x)) = x
you can try for any function, i.e.
f(x) = 2x + 1
f-¹(x) = (x-1)/2
f-¹(f(x)) = (2x + 1 - 1)/2 = x
f(f-¹(x)) = 2((x-1)/2) + 1 = x - 1 + 1 = x
$301 = $5h + $186
B.
$301 = $186h + $5
C.
$301 = $186h - $5
D.
$301 = $5h - $186
Answer:
A
Step-by-step explanation:
Let's set hours as h.
We know that she earns 5 dollars an hour. If, for example, she worked 2 hours, she would have earned 2*5=10 dollars. This is 5h.
Next, we know that she got 186 dollars in tips. Tips means that she earned extra money, so therefore, the equation is 5h+186, or A
