Step-by-step explanation:
no of days = (15×12)/20= 9 days
I hope this helps
A) There are 8 possible values for each of the 3 digits, so the number of possible codes is
.. 8 * 8 * 8 = 512
b) The probability that a randomly selected code is correct is 1/512.
c) The probability it is not correct is 1 -1/512 = 511/512.
Answer:
Step-by-step explanation:
The given function is
If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.
If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is
Substituting the value of function f(x), we get
Therefore, the required function is .
