Answer: Bradley would expect 94 times to get a blue or green gumball.
Step-by-step explanation:
Since we have given that
Number of blue gumballs = 15
Number of yellow gumballs = 12
Number of green gumballs = 2
Number of purple gumballs = 16
Total number of all gumballs = 45
Probability of getting either a blue gumball or green gumball be
So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :
Since we know that it must be less than 94.4.
So, the nearest smallest integer will be 94 times .
Hence, Bradley would expect 94 times to get a blue or green gumball.

ANSWER:
{(2,4),( 3, 6),(4, 8)} is a function
Given a relation in x and y, we say y is a function of x if for each element x in the domain, there is exactly one value of y in the range. It is a rule of correspondence between two nonempty sets, such that, to each element of the first is called domain, there correspondents one and only one element of the second is called range.
To determine whether it is function or not by using the vertical line test. If the graph passed to Vertical line test it is consider as function. The graph of function defines y as a function of x if no vertical line intersects the graph in more than one point.
The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) . The second example is not a function, because it contains the ordered pairs (1,2) and (1,4). the first set is repeated . These have the same first coordinate and different second coordinates.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.

Explanation:</h3>
(f-g)(x) = f(x) -g(x) = (4x²+1) -(x²-5) . . . . . substitute the function definitions
... = 4x² +1 -x² +5 . . . . . . . . . . . eliminate parentheses
... = (4-1)x² +(1+5) . . . . . . . . . . . collect like terms
... = 3x² +6
