Using the Fundamental Counting Theorem, it is found that for each case, the total number of outcomes is:
a) 60,466,176.
b) 5,961,600.
What is the Fundamental Counting Theorem?
It is a theorem that states that if there are n things, each with n1, n2, ... ways to be done, each thing independent of the other, the number of ways they can be done is N=n1*n2*n3*....
Item a:
No restrictions, hence, for each of the five characters, there are 36 outcomes, hence n1=n5=36.
Then, the possible number of passwords is:
N=36^5=60,466,176
Item b:
The letters and the digits have to be alternated, hence:
Starting with a letter n1=n3=n5=36, n2=n4=10.
Starting with a digit n1=n3=n5=10, n2=n4=36.
Then, the possible number of passwords is:
N=36^3*10^2+10^3*36^2=5,961,600.

Step-by-step explanation:
Alex and Monte are shopping for new clothes. Alex says to Monte, "If you give me $12, we will have an equal amount of money." Monte responds, "That may be true, but if you give me $6, I will have twice as much as you.
The question is a word problem, where; the amount of money Alex has is the same as the amount Monte will have if he gives Alex $12, and the amount of money Monte will have will be twice the amount with Alex if he receives $6 from Alex, indicating that the amount of money Alex has is $30, while the amount of money with Monte is $54.
What is a word problem?A word problem is a verbal presentation of a mathematical or science question, using words and sentences, rather than numbers and symbols, and for which the solution is found mathematically, or by using standard scientific steps.
Let x represent the amount of money Alex has, and let y represent the amount of money Monte has, we get;
x + 12 = y - 12...(1)
2·x = y + 6...(2)
Adding 12 to both sides of equation (1), we get;
x + 12 + 12 = y - 12 + 12
x + 24 = y - 0 = y
x + 24 = y
y = x + 24
Plugging in the value of y into equation (2), we get;
2·x = y + 6
2·x = x + 24 + 6 = x + 30
2·x = x + 30
Subtracting x from both sides of the above equation, we get;
2·x - x = x + 30 - x
x = x - x + 30 = 0 + 30
x = 30
The amount of money Alex has, x = $30
y = x + 24
Therefore; y = 30 + 24 = 54
The amount of money Monte has, y = $54

Answer: $2.25
Step-by-step explanation:
We are required to find the cost per kilometer of Emmanuel.
The cost per kilometre is $2.25 OR $2 and 25cents.
According to the question, the total cost of the journey = $32
The total distance covered during the journey =
14 2/9 km
Therefore, the cost per kilometre can be evaluated mathematically as follows;
Cost per kilometer = cost of the journey ÷ Distance of the journey
= 32 ÷ 14 2/9
By converting 14 2/9 to an improper fraction; we have;
= 32 ÷ 128 / 9
= 32 × 9/128
= (32×9) / 128
= 288 / 128
= 2 32/128
= 2.25 dollar per kilometer
Therefore, the cost per kilometer is $2.25

10 + 5Y = X
40 + 10Y = X
Answer:
X = -50
Y = -30
Step-by-step explanation:
To find the value of Y and X, we can solve a system of equations. One way to do this is by substitution.
From the first equation:
10 + 5Y = X
We can substitute the value of X from the second equation:
10 + 5Y = 40 + 10Y
Then, we can subtract 10Y from both sides:
10 = 40 + Y
Finally, we can subtract 10 from both sides:
Y = -30
Now that we have the value of Y, we can substitute it back into either equation to find the value of X:
X = 10 + 5Y
X = 10 + 5(-30)
X = -50
So the solution is:
X = -50
Y = -30

Alexa took out a 12-year loan for $72,000 to pay for her home. If she paid
an extra $20,000 in interest, then what was her interest rate?
If the home loan compounds 12 times per year, her interest rate (APR) is 24.764%.
What is the annual percentage rate (APR)?The annual percentage rate (APR) is the yearly cost of borrowing.
The annual percentage rate (APR) is computed as the interest rate times the principal (balance).
The APR can be computed using an online finance calculator.
N (# of periods) = 12 years
PV (Present Value) = $72,000
PMT (Periodic Payment) = $0
FV (Future Value) = $-92000
Results:
I/Y = 24.764% if interest compound 12 times per year (APR)
I/Y = 27.778% if interest compounds once per year (APY)
I/period = 2.064% interest per period
Total Interest = $20,000.00

what is plotting data?The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables. Diagrams created by hand or on a computer are also acceptable. Move 2 units to the right after starting at the origin before going 3 units up. The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points. The pink dot with the letter P thus stands for 2.3. Before creating a line chart, you need first generate a number line for each value in your data collection. Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

Which equation can pair with x – y = –2 to create a consistent and dependent system?
6x + 2y = 15
–3x + 3y = 6
–8x – 3y = 2
4x – 4y = 6
The required equation -3x + 3y = 6 can pair with x - y= -2 to create a consistent and dependent system.
The equation is given in the question, as follows:
x - y = - 2
First, we have to convert the standard form of the equation to slope-intercept form.
As per the question, we have
x - y = -2
Subtract x from both sides of the equation,
x - y - x = -2 - x
- y = -2 - x
Divide -1 by both sides of the equation,
y = x + 2
Comparing it with the slope-intercept form y = mx + b, we get
Slope m = 1, y intercept b = 2
Considering option (B),
-3x + 3y = 6
Add 3x on both sides of the equation,
-3x + 3x + 3y = 6 + 3x
3y = 3x + 6
Divide both sides by 3 of the equation,
y = x + 2
Comparing the slope-intercept form
m = 1 and y-intercept = 2

What is standard deviation?You should be aware that Standard deviation explains the relation of data with mean.
For normal distributions, 68% of the data lies under one SD from the mean. Two standard deviations is within 95%, and three standard deviations would take up to 99%.
This implies that on taking (mean + SD) and (mean - SD), 68% of data would cover these two numbers.
Add and subtract SD from the mean to check which location will give $19,371.18 and $22.295.48.
For location A, we have
M-SD=23,124.70-1553.43=21,571.27
M SD = 23,124.70 + 1,553.43 = 24,678.4

f:x > x^2-2x-1 g:x > x-1For the function (x)=g(x)-2
Substitute the values, we get;
x² -2x - 1 = x - 1 - 2
collect like terms
x² - 2x - x = -3 + 1
add or subtract like terms
x² -3x + 2 = 0
x² - 2x - x + 2 = 0
(x² -2x) - (x + 2) = 0

question 4 of 5
D - If written in radical form, 7 would be the index.
E - If written in radical form, 9 would be the index.
Answer:
A - The exponent of 3 is 7/9.
Step-by-step explanation:
The expression 3^(7/9) can be read as "3 to the power of 7/9".
This means that the number 3 is being multiplied by itself 7/9 times.
For example
3^(2/3) can be written as cube root of 3, cube root of 3 is equal to 3^(1/3) .
When the exponent of an expression is a fraction, it can be written in radical form, with the denominator of the fraction as the index of the radical. However, it's not true in this case as the index is not 9 but 7.
So, the correct answer is A - The exponent of 3 is 7/9.
