There are 36^7 different passwords available, incluiding ones that have repeated characters, are sequential characters, or are all the same letter or digit. Of these 26^7 are invalid. the probability of obtaining a valid password is
... 1 - 26^7/36^7 ≈ 0.8975
It is given to us that the interest rate is 2%.
We know that 2% can be rewritten as 
. Now, we also know that in decimal form, 
.
Therefore, the interest earned on d dollars at an interest rate of 2% will be "2% of d" which can be rewritten as
. This is because in math, "of" means the same as multiplication.
Thus, out of the given options, the last option is the correct option.
Answer:
x = - 1, y = 4
Step-by-step explanation:
A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.
B.
x + 2y = 7
<u>+ 3x - 2y = -11</u>
4x = - 4
x = - 1
x + 2y = 7
-1 + 2y = 7
2y = 8
y = 4

hello
Answer:
width=14 &Length = 70( can add unit behind the answer e.g.cm or mm etc..)
Step-by-step explanation:
we know that in a rectangle not all side are same compare to a square..
therefore:
1) write the formula for perimeter down
perimeter = the sum of all side
perimeter = 2x(width) + 2x(length)
P=2(w)+2(L)
2) substitute into the equation
P =2(w)+2(L)
84=2(w)+2(5*w)
3) perform opposite operation to make w become the subject of the formula inorder to find width
48=2(w)+2(5*w)
48=2w+10w
48=12w
48/12=12w/12( the twelves cancels out)
7=w or the width is 7
4) rewrite the formula and solve
P=2(w)+2(L)
P =2(7) + 2(5*7)
P = 14 + 70
P = 48
