In mathematics, a constant function is one defined in
which a function whose output value (y) is the same for every value of the
input variable (x). Therefore this means that whatever is the value for x, the
value of y would always be the same. Hence we can say that the function is a
straight horizontal line in a Cartesian plane.
Since the value of y does not change, and the average rate
of change has the formula:
average rate of change = (y2 – y1) / (x2 – x1)
So y2 – y1 = 0 therefore average rate of change is also
zero.
Hence to complete the sentence:
For a constant function, the y-coordinate is <u>the same</u> for
every pair of points selected, so the average rate of change always has a value
equal to <u>zero</u>.
Y = -(2^3) = -8 (substitute x=3)
Answer:
Step-by-step explanation:
The sum is larger than 9, it means we have: 10, 11, and 12
- To get the outcome is 12, we have only one way is that the two dice shows face-6. The probability to have 12 is:
P(12) = 
= 
- To get 11, we have it two ways once dice shows face-5 and the other shows face-6 and vice versa
P(11) = 2* = 
- To get 10, we have it three ways ( once dice shows face-5 and the other shows face-6 and vice versa , two dice show 5)
P(10) = 3* = 
So the probability of getting a number larger than 9 for the first time on the third roll is:
P(12) + P(11) +P(10 )
= + + =
Answer:
at least 99
Step-by-step explanation:
each number starting from 2 can be moved 11 times per thing.
