Answer:
C.) Number of successful trials / Total number of trials
Step-by-step explanation:
The empirical probability of an event 'E' is defined as :
(Number of successful occurrences of event 'E' / Total number of trials)
The empirical probability requires that an experiment of a chosen number of trials be performed. The ratio of the number of success to the total number of trials is used to estimate the empirical probability of such event.
P(Empirical) = (Number of successful trials / Total number of trials)
This is different from the use of sample space in the evaluation of theoretical probability whereby all possible occurences is used to estimate the probable outcome of an event.
P(theoretical) = (number of required outcomes / total number of possible outcomes)
Answer:
slope: -3
y-intercept: -2
equation: -3x-2
y intercept is the value of y at x=0
slope is how many units the graph moves per x
equation is (slope)x+(y-intercept)
Answer:
A plane extends infinitely in two dimensions. It has no thickness. An example of a plane is a coordinate plane. A plane is named by three points in the plane that are not on the same line.
Step-by-step explanation:
It would be a horizontal line at where on the y axis is 3, representing that for all x values the output is 3
Answer:
B. -4
Step-by-step explanation:
To find the slope you can count the difference between the 2 points. Slope is rise over run. This means that slope is equal to change in y/ change in x. In this case, the 2 y-values are 8 and -4. This is a decrease of 12, aka -12. Then, the 2 x-values are -1 and 2. This is an increase of 3. Therefore the slope is -12/3. When simplified this equals -4.
Additionally, there is a slope formula, . If you plug in the values, you will get the same answer as the technique above.
