Determine first the places that will be filled:
26 + 26 + 10 = 62 ways
The number of possible passwords is limited to 12 characters
Thus,
= 62^12 (assume that repetition is allowed)
The probability of guessing correctly =
(1/62)^12
= 3.099557704 x 10^-22 (note that it is in scientific notation form)
Answer:
1. y=-x
2. y=-3/2x-2
3. x=4
4. y=-2x-1
Step-by-step explanation:
slope intercept form is y=mx+b with mx being the slope and b being the y intercept
if its parallel it has to have the same slope.
perpendicular lines have the opposite slope and sign. so if its a whole number you put it over 1 and if its a fraction you switch the values in the numerator and denominator in addition to changing the sign. You keep the y intercept the same.
Answer:
(A) 
Step-by-step explanation:
To Simplify: The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.
Solution: The given statement can be easily rewritten as:
,
and

Thus, according to the statement, the expression can be written as:

⇒
which is the required simplified expression.
Thus,option A is correct.
Answer:
Step-by-step explanation:22/ 30 just divide by 3
100-75=25% did not like
25%=35 students how about 75%
75 x 35 divided by 25=105 students
