The access code for a car's security system consists of 6 digits, the first digit cannot be 8 and the last digit must be odd, how many different codes are available
Answer:
There are 450000 possible different codes
Step-by-step explanation:
Given
Code = 6 digits
First = All but 8
Last = Odd
Required
Determine the possible number of codes
Analyzing each individual digit that makes up the code.
First: can be any of 0,1,2,3,4,5,6,7,9 ----- 9 possible numbers
Second, Third, Fourth and Fifth can be any of 0,1,2,3,4,5,6,7,8,9 since there's no restriction ----- 10 possible numbers
Last can be any of: 1,3,5,7,9 ----- 5 possible numbers
So, the number of possible selections is:
[tex]Selection = 9 * 10 * 10 * 10 * 10 *5[/tex]
[tex]Selection = 450000[/tex]
Hence, there are 450000 possible different codes

Can someone check this for me please?
Answer:
B. -4, -3
Step-by-step explanation:
The equation x^(2) + 7x + 12 can be factored using the AC method resulting in
( x + 4 )( x + 3 ). So x = -4, -3. You can use foil to check.
The bill for the repair of a computer was $179. The cost for parts was $44, and the labor charge was $45 per hour. How many hours did it take to repair the computer?
1. Define the variable (What do we not know?):
2. Write the equation .
3. Solve the equation.
Answer:
1. x is the amount of hours it took to repair the computer
2. 44+45x=$179
3. Around 3 hours
Step-by-step explanation:
44+45x=$179
Subtract 44 on both sides:
44-44+45x=179-42
45x=137
Divide 45 on both sides:
45x/45=137/45
x=3.044444444
Around 3 hours.
You win an online auction for a toy. Your winning bid of $60 is 75% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
The maximum amount of bid for the toy will be equal to $80.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that you win an online auction for a toy. Your winning bid of $60 is 75% of your maximum bid.
The maximum bid will be calculated as,
Maximum bid = ( 100 x 60 ) / 75
Maximum bid = $80
Therefore, the maximum amount of bid for the toy will be equal to $80.

Find the next three terms of the following arithmetic sequence -2, -5, -8, -11,
Answer: -14, -17, and -20
Step-by-step explanation: Study the sequence.
Notice that each number is 3 less than the number before it.
In other words, -2 - 3 is -5, -5 - 3 is -8, and -8 - 3 is -11.
Now, if we continue with this same sequence,
-11 - 3 is -14, -14 - 3 is -17, and -17 - 3 is -20.
So the next three numbers are -14, -17, and -20.

Making the assumption of no compounding interest, suppose you purchase a perpetuity bond from Sense/Net Corporation for $4,000 with an annual coupon rate of 3% . Specify all answers to the nearest dollar, and assume a discount rate equal to that of the current interest rate. What is the yearly return on your $4,000 investment?
Answer:
$120
Explanation:
Data provided as per the given question below:-
Investment = $4,000
Coupon rate in percentage = 3%
The computation of yearly return is shown below:-
Yearly return = Investment × Coupon rate in percentage
= $4,000 × 3%
= $120
Therefore for computing the yearly return we simply investment with coupon rate in percentage.

Need help finding the parallel and perpendicular slope
Answer:
Step-by-step explanation:
(x₁, y₁) = (19 , -4) & (x₂ ,y₂) = (17, -20)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{-20-[-4]}{17-19}\\\\= \frac{-20+4}{17-19}\\\\= \frac{-16}{-2}\\\\= 8[/tex]
m = 8
Parallel lines have same slope.
Parallel slope = 8
Slope of perpendicular line = [tex]\frac{-1}{m}[/tex]
Perpendicular slope = [tex]\frac{-1}{8}[/tex]

Nora makes $3000 a month. If she spends 10% of that on clothes each month, how much does she spend on clothes?
Answer:
$300
Step-by-step explanation:
10% converted into a decimal is 0.10.
To find 10% of 3,000, you would multiply them.
3,000 times 0.10 is 300.
Therefore, Nora spends $300 a month on clothes.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\cdot(n-k)!}[/tex]
(a)
Compute the number of ways to select 9 applicants from 100 as follows:
[tex]{100\choose 9}=\frac{100!}{9!\cdot(100-9)!}[/tex]
[tex]=\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400[/tex]
(b)
Compute the number of ways to select 6 people from 9 as follows:
[tex]{9\choose 6}=\frac{9!}{6!\cdot(9-6)!}[/tex]
[tex]=\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84[/tex]
(c)
Compute the number of ways to select top 3 candidates from 6 as follows:
[tex]{6\choose 3}=\frac{6!}{3!\cdot(6-3)!}[/tex]
[tex]=\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20[/tex]
