Answer:
a) Function? No
b) Domain: 
c) Range: 
Step-by-step explanation:
a) Function? No
We want to determine whether the graph of the relation is a function or not.
When we draw a straight line at x=-1, it will intersect the graph at several points, therefore the graph fails the vertical line test and hence it is not a function.
b) The domain refers to all x-values for which the function is defined.
From the graph the domain is because the ends of the graph are closed.
c) The range is the set of all y-values for which the graph is defined.
From the graph the range is
Answer:
Step-by-step explanation:
The standard deviation (SD) can be defined as a entity that measures the amount of dispersion for a set of data from the mean, while the standard error of the mean (SEM) measures the magnitude of deviation of the sample mean of the data from the true population mean.
Answer: 15x - 45
Step-by-step explanation:
(5)(3x) = 15x
(5)(-9) = 45
Answer:
44
Step-by-step explanation:
crop the square into two, then you can see tangent which is 90°.
so, 360-90-90-136=44
Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have
Sample size : n= 35
Let 
be the sample mean.
Now ,
Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
