Answer:
answer is : A. 1010
Step-by-step explanation:
A license plate has 3 letters and 3 digits in that order. a witness to a hit-and-run accident saw the first 2 letters and the last digit. if the letters and digits can be repeated, how many license plates must be checked by the police to find the culprit?
The police must check 2600 possible license plates, calculated by multiplying 26 possibilities for the third letter not seen by the witness with 100 possibilities for the two digits also not seen.
To determine how many license plates the police must check to find the culprit, we consider the information that the witness saw the first two letters and the last digit. Since letters can be repeated, there are 26 possibilities for each of the two letters the witness saw. For the last digit, which the witness also saw, there are 10 possibilities (0 through 9). The third letter and the other two digits, which the witness did not see, each have the following number of possibilities: 26 for the third letter, and 10 for each of the two remaining digits.
Calculating the number of possible combinations:
First two letters (seen by the witness): 26 * 26 = 676 possibilitiesLast digit (seen by the witness): 10 possibilitiesThird letter (not seen by the witness): 26 possibilitiesThe two remaining digits (not seen by the witness): 10 * 10 = 100 possibilitiesTherefore, the total number of license plates the police must check is the product of the possibilities for the parts the witness did not see:
26 (third letter) * 100 (two remaining digits) = 2600 possible license plates.

Calculate the total cost of the order: Veggiburger with cola and soup, sales tax 4%, tip 15.
Veggiburger: $3.25
Cola: $1.50
Soup: $2.25
A $8.33
B $7.28
C $7.00
D $5.50
The cost of the order, including the sales tax of 4%, comes out to be $7.28. However, the tip is unclear in the question. If it's 15%, the cost rises to $8.37, but none of the provided options match this result.
Explanation:The first step is to calculate the total cost of the Veggiburger, cola, and soup by adding them together. So, $3.25 (Veggiburger) + $1.50 (cola) + $2.25 (soup) = $7.00. Next, apply the 4% sales tax on this amount which is $7.00 * 4/100 = $0.28. So the subtotal now is $7.28 ($7.00 + $0.28). Finally, the tip mentioned in the problem is not clear whether it is a percentage or a fixed amount. If it is a 15% tip, then calculate 15% of the subtotal, i.e $7.28 * 15/100 = $1.09 (Approx). Adding this to the subtotal we get $8.37 which is not an option in the given answers. If $15 is a fixed tip amount, the total cost would be substantially larger. Please ensure the tip amount is correct.

Compute the stock turnover in dollars for a product that has sales of $6,000 and an average value of inventory investment of $1,500.
Answer: 4
Step-by-step explanation:
Given: Cost of product sold = $6,000
Average value of inventory= $1,500
We know that the inventory turnover formula is given by :-
[tex]\text{Inventory turnover}=\frac{\text{ Cost of product sold}}{\text{Average value of inventory}}[/tex]
[tex]\\\Rightarrow\ \text{Inventory turnover}=\frac{\$6,000 }{\$1500}\\\\\Rightarrow\ \text{Inventory turnover}=4[/tex]
Therefore, the stock turnover for a product that has sales of $6,000 and an average value of inventory investment of $1,500 = 4

what is the sum of the geometric series E (-2)(-3)^n-1
Answer:
The sum is 40.
Step-by-step explanation:
Given,
[tex]\sum_{n=1}^{4} (-2)(-3)^{n-1}[/tex]
We know that,
[tex]\sum_{n=1}^{4} (-2)(-3)^{n-1}=(-2)(-3)^{1-1}+(-2)(-3)^{2-1}+(-2)(-3)^{3-1}+(-2)(-3)^{4-1}[/tex]
[tex]=(-2)(-3)^{0}+(-2)(-3)^1+(-2)(-3)^2+(-2)(-3)^3[/tex]
[tex]=-2\times 1 - 2\times - 3 - 2\times 9-2\times -27[/tex]
[tex]=-2+6-18+54[/tex]
[tex]=40[/tex]
Hence,

Multiply: (2x2 − 5x)(4x2 − 12x + 10)
Answer:
[tex]8x^4-44x^3+80x^2-50x[/tex]
Step-by-step explanation:
The given expression is
[tex](2x^2-5x)(4x^2-12x+10)[/tex]
Using distributive property we get
[tex]2x^2(4x^2-12x+10)-5x(4x^2-12x+10)[/tex]
[tex]2x^2(4x^2)+2x^2(-12x)+2x^2(10)-5x(4x^2)-5x(-12x)-5x(10)[/tex]
On simplification we get
[tex]8x^4-24x^3+20x^2-20x^3+60x^2-50x[/tex]
On combine like terms.
[tex]8x^4+(-24x^3-20x^3)+(20x^2+60x^2)-50x[/tex]
[tex]8x^4-44x^3+80x^2-50x[/tex]
Therefore the product of two polynomials is [tex]8x^4-44x^3+80x^2-50x[/tex].

find two factor of 9 such that its product gives 9 and its sum gives 6 (3 and 3, 3×3 = 9 , also 3+ 3=6)
we are going to replace 6x by 3x + 3x
9x² + 6x + 1
9x² + 3x +3x + 1
3x(3x + 1) + 1(3x+ 1)
(3x + 1)(3x+1)
The correct factorization of the trinomial 9x² + 6x + 1 is (3x + 1)(3x + 1) or (3x + 1)². option D.
How do we identify the correct option when the trinomial is factorized?The trinomial 9x² + 6x + 1 is a perfect square trinomial, which can be factored as the square of a binomial.
Let's find the correct answer from your options:
(A) (3x + 1)(3x - 1): The difference of squares isn't the correct form for our trinomial.
(B) (9x + 1)(x - 1): Expanding this will not give us the original trinomial.
(C) (9x + 1)(x + 1): Expanding this will not give us the original trinomial.
(D) (3x + 1)(3x + 1): When expanded, this gives us 9x^2 + 3x + 3x + 1, which simplifies to 9x² + 6x + 1.
Therefore option D (3x + 1)(3x + 1) is correct

PLS HELP! Tanisha is planning a party. She will serve hamburgers, potato salad, strawberry shortcake, and lemonade. Including Tanisha, 28 people will be at the party. Tanisha expects that each person will drink two 8−ounce glasses of lemonade at the party, and makes 448 ounces of lemonade. Tanisha's mother buys 38 lemons. They know it takes 8 lemons to make 80 ounces of lemonade. Does Tanisha need more lemons?
Answer: 7 more lemons
Step-by-step explanation:
Since she needs 448 ounces of lemonade you have to divide which is 5.6 . As a result there are 5.6 80 ounces of lemonade. 80 ounces needs 8 lemons. 448 ounces of lemonade are needed 8 x 5.6 = 44.8 lemons. Tanisha only has 38 lemons, which isn't enough. 44.8 - 38 = is about 7 more lemons.

someone please help asap! Which statement is most likely true for this distribution?
Answer:
C) The mean is greater than the median.
Step-by-step explanation:
This distribution is right skewed; that means it has a longer tail to the right and the data is "bunched up" at the left.
In a right skewed distribution, the majority of data points are at the smaller end; for this reason, the median will be towards the left side of the graph.
The higher numbers in the "tail" will bring the mean up, making it larger than the median.
The correct statement for the distribution is the mean is greater than the median.
What is mean and median?
The mean is the average of a data set. The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
The median is the middle term of a distribution.
It measure determines the middle value of a dataset listed in ascending order.
Therefore, from the distribution the data are rightly skewed. The higher numbers in the "tail" will bring the mean up, thereby making it larger than the median.

match the following situation with one of the linear systems. Lewis wants to acquire at most 12 packages of baseball cards. Some packages have 4 rookie cards and some have only 3. In all, there are at most 38 rookie cards.
A.
B.
C.
D.
The correct linear system for the student's question is D. x + 3y \<= 38, x + y \<= 12, which matches the conditions of Lewis's situation for acquiring baseball cards.
The student is looking to match a situation with a linear system. The situation is that Lewis wants at most 12 packages of baseball cards, some containing 4 rookie cards and others 3 rookie cards, with a total of 38 rookie cards at most.
To match the situation with the correct linear system, we must set up two inequalities: one for the number of packages and another for the number of rookie cards.
Let x represent the number of packages with 4 rookie cards and y represent the number of packages with 3 rookie cards.
The first condition is that Lewis can have at most 12 packages, which gives us the inequality x + y \<= 12. The second condition is that the total number of rookie cards is at most 38, which gives us the inequality 4x + 3y \<= 38.
Considering these conditions, the correct answer is: D. x + 3y \<= 38, x + y \<= 12.

How many arrangements are possible using the letters in the word fuzzy if each letter "z" is distinctly different than the other? how many arrangements are possible if the letter "z" is interchangeable with the other? explain your reasoning?
When each letter "z" is distinctly different, there are 60 possible arrangements.
When the letter "z" is interchangeable with the others, there are 24 possible arrangements.
1. When each letter "z" is distinctly different from the others:
- The word "fuzzy" has 5 letters in total, including 2 "z" letters.
- To calculate the number of arrangements, we use the formula for permutations with repeated elements:
- The formula is: n! / (n1! n2! ... * nk!)
- n is the total number of letters in the word (5 in this case).
- n1, n2, ... are the number of repetitions of each distinct letter.
- Calculating: 5! / (1! 2! 1! * 1!) = 120 / 2 = 60 arrangements.
2. When the letter "z" is interchangeable with the other letters:
- In this case, there are 4 distinct letters in the word "fuzzy" (f, u, z, y).
- The total number of arrangements can be calculated using the formula for permutations of distinct items.
- Calculating: 4! = 24 arrangements.
In summary:
- When each letter "z" is distinctly different, there are 60 possible arrangements.
- When the letter "z" is interchangeable with the others, there are 24 possible arrangements.
