With lower case numbers and numerals from 0-9 there are about <u>4,738,381,338,321,616,896 possible passwords.</u>
<u></u>
Add up the number of possible numbers and letters.
There are 26 letters in the alphabet, 0-9 would mean 10 digits. Which is 36.
The length of the password she wants is 12.
36 to the power of 12 = 4738381338321620000
4738381338321620000
Answer: 2n + 8 = n -3
Step-by-step explanation:
In this scenario we will represent that number by the variable n.
So two times the number will be 2n plus 8 is 2n +8 and it has to equal 3 less that number so it will be n-3.
Answer:
a) There is no significant difference between the mean amounts charged
b) The skewness threatens the validity of the test
Step-by-step explanation:
<em>Given data:</em>
Group n x s
A 150 $1,987 $392
B 150 $2,056 $413
n1 = n2 = 150
x1 = 1987
x2 = 2056
s1 = 392
s2 = 413
∝ = 0.05
Attached below is the detailed solution
Well if my math is correct, x= -7, meaning 4x-4= (4*-7)-4. That equals -32.
Hope this helps.
