The probability that the hacker guesses the password on his first try is:
P = 1/(62^10) = 1.19*10^(-18)
We know that the password is 10 characters long.
In each one of these, we can put.
One lower case letter (26 of these)
One upper case letter (26 of these)
one numerical digit (10 of these)
So, for every single digit, we have a total of:
26 + 26 + 10 = 62 options
Now we can find the total number of different passwords, which will be equal to the product between the number of options for each one of the characters.
We know that for each character we have 62 different options.
And we have 10 characters.
Then the product between the numbers of options is:
C = 62^10
Then if the hacker does a random guess, the probability that the random guess is correct is one over the total number of possible combinations.
P = 1/C = 1/(62^10)
The probability that the hacker guesses the password on his first try is:
P = 1/(62^10) = 1.19*10^(-18)

Answer:
Xbar = 20.813
Median = 19.95
5 - number summary :
Minimum = 15.2
Q1 = 19.05; Q2 = 19.95 ; Q3 = 21.95 ; maximum = 29.4
Standard deviation, s = 4.068
Step-by-step explanation:
Given the data:
X : 15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4
Ordered data:
15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4
The mean (xbar) :
Xbar = Σx / n ; n = sample size = 8
Xbar = 166.8 / 8 = 20.8125
Xbar = 20.813
The median :
1/2 *(n+1)th term
1/2(9) = 4.5
(4 + 5)th term / 2
(19.7 + 20.2) / 2 = 19.95
The five number summary :
Minimum = 15.2
Lower quartile (Q1) = 1/4(9) = 2.25 ; (2nd + 3rd) term / 2
(18.8 + 19.3) / 2 = 19.05
Median (Q2) = 19.95
Upper quartile (Q3) :
3/4(9) = 6.75 = (6th + 7th) / 2
(21.8 + 22.1) / 2 = 21.95
Maximum = 29.4
The standard deviation, s = sqrt[(x - xbar)²/ (n-1)]
Using calculator ;
s = 4.068

Solve the following systems of equations using the substitution method. 6x + 2y = 82 and x − y = 3 y = 4x − 1 and x + y = 9 4x + 3y =17 and y = 5 − x
Step-by-step explanation:
puhhh ! that way of typing can be misleading.
let me sum up what equations I think the problem definition specified :
1)
6x + 2y = 82
x - y = 3
2)
y = 4x - 1
x + y = 9
3)
4x + 3y = 17
y = 5 - x
solving 1)
x - y = 3 => x = y + 3
putting this into the first equation
6×(y+3) + 2y = 82
6y + 18 + 2y = 82
8y +18 = 82
8y = 64
y = 8
x = y + 3 = 8 + 3 = 11
solving 2)
using the first equation in the second equation
x + (4x - 1) = 9
5x - 1 = 9
5x = 10
x = 2
y = 4x - 1 = 4×2 - 1 = 8 - 1 = 7
solving 3)
using the second equation in the first equation
4x + 3×(5 - x) = 17
4x + 15 - 3x = 17
x + 15 = 17
x = 2
y = 5 - x = 5 - 2 = 3

Find a 2-digit number smaller than 50, the sum of whose digits does not change after being multiplied by a number greater than 1
To solve this question, it is needed to know that the sum of the digits of numbers which are multiples of 9 greater than 1, add to 9, that is:
Multiples of 9:
9*1 = 9
9*2 = 18 -> 1 + 8 = 9
9*3 = 27 -> 2 + 7 = 9
9*4 = 36 -> 3 + 6 = 9
9*5 = 45 -> 4 + 5 = 9
Find a number:
Thus, there are 4 possible options for the desired 2-digit number less than 50:
18, 27, 36, 45.

Answer:
B
Step-by-step explanation:
Given arc FG then the central angle is the angle at the centre subtended by FG , that is
central angle = ∠ FQG
The central angle is B i.e ∠FQG
What is central angle?A central angle exists an angle whose vertex stands present at the center of a circle created by the two radii as the sides of the angle.
In Mathematics, an “arc” exists as a smooth curve joining two endpoints. In general, an arc exists one of the portions of a circle. It is essentially a part of the circumference of a circle. Arc exists as a part of a curve. An arc can be a portion of some other curved constitutions like an ellipse but mostly guides to a circle.
The angle substended by the arc would be ∠FQG.
