The slope of f is m= -0.05577.
Given : The winning times for the 200-meter dash can be approximated by f(x) = - 0.05577x+146.2 , where x is the year.
To find : The slope of f
Solution : Using slope intercept form a linear function is represented as
y = mx+b
where, m is the slope and b is the y-intercept.
We can write the function as f(x) = - 0.05577x+146.2
Comparing with slope intercept form,
m= -0.05577 and y-intercept = 146.2
Therefore, The slope of f is m= -0.05577

Answer:
d. A hypothesis is derived from the evidence at hand; the evidence produces the hypothesis.
Step-by-step explanation:
Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The evidence suggests that a certain hypothesis is tested for its reliability. The hypothesis is accepted or rejected on the basis of its underlying evidences.
The equation y= 2x - 8
Because the temperature rises by 2 every hour we have 2x and we have to remove 8 because the initial temperature is -8 F.
Answer:
It is very difficult to read the points off of the graph as it is a little blurry
but
They are NOT parallel
red= 5/8
blue = 3/7 i think
