According to Newton's second law of motion, the force acting on an object is equal to the mass multiplied by the acceleration of the moving object. Since the object is moving in a constant velocity, acceleration is zero. Hence regardless of the mass of the car, the force acting is zero provided that air resistance and friction is negligible
Answer:
Option a) I and III only
Step-by-step explanation:
given that a test statistic is found to have a P-value of .015.
In hypothesis testing after finding out test statistic as difference between hypothesises mean and sample mean divided by standard error of sample we find out p value.
Significance level, known as alpha is fixed as 5% or 1% or 10% depending on the matter of interest
If p value calculated is less than our significance level i.e. alpha we reject null hypothesis
Here p = 0.015 is less than 5% and 10% but greater than 1%
So we reject at 5% and 10% level and but accept at 1% level
Correct options would be:
I. This finding is significant at the .05 level of significance.
III. The probability of getting a test statistic as extreme (or more extreme) as this one by chance alone is .015
Option a) I and III only

Answer:
(a) y = −50x + 250
Step-by-step explanation:
In case you don't realize that the graph starts at 250 and decreases by 50 for each increase of 1 in x, you can see if any of the equations match the given points. The only one that does is the first one:
y = -50x +250
