a person owns three suits, ten ties, and ten shirts. how many ways can they select a traveling wardrobe of two suits, four ties and six shirts?
There are a total of 3 x 10 x 10 = 300 possible combinations of suits, ties, and shirts that a person can select from. However, when selecting a traveling wardrobe, there are only 10 possible suit combinations, 10x10 = 100 possible tie combinations, and 10x10x10 = 1000 possible shirt combinations. This makes a total of 10 x 100 x 1000 = 100,000 possible selections of two suits, four ties and six shirts.
The sheer number of possible combinations indicates how important it is to choose wisely. The two suits should be complementary and appropriate to the occasion; the four ties can be chosen to match the suits, and the six shirts should be selected to mix and match with the ties and suits. Care should be taken to avoid repeating clothing items, and the person should also consider the climate and purpose of the trip in order to select the most suitable wardrobe.

Select the recursive and explicit formulas that model the scenario.
The recursive and the explicit formulas are f(n) = 3f(n - 1), where f(1) = 250 and f(n) = 250(3)ⁿ‐¹
Calculating the recursive and explicit formulas that model the scenario.From the question, we have the following parameters that can be used in our computation:
Initial = 250 bacterial cultures.Rate = triples every hour.This means that
Initial, a = 250 bacterial cultures.
Rate = 3
So, the recursive formulas is
f(n) = 3f(n - 1), where f(1) = 250
For the explicit formula, we have
f(n) = 250(3)ⁿ‐¹
Hence, the recursive and the explicit formulas are f(n) = 3f(n - 1), where f(1) = 250 and f(n) = 250(3)ⁿ‐¹

Which is the polynomial function of lowest degree that has –5, –2, and 0 as roots? f(x) = (x – 2)(x – 5) f(x) = x(x – 2)(x – 5) f(x) =(x 2)(x 5) f(x) = x(x 2)(x 5)
The polynomial function of the lowest degree that has -5, -2, and 0 as roots is f(x) = (x - 2)(x - 5).
To find the polynomial function of the lowest degree with -5, -2, and 0 as roots, we can use the factored form of a polynomial. If a number is a root of a polynomial, it means that when we substitute that number into the polynomial, the result is equal to zero.
In this case, we have the roots -5, -2, and 0. To construct the polynomial, we can write it in factored form as follows: f(x) = (x - r1)(x - r2)(x - r3), where r1, r2, and r3 are the roots.
Substituting the given roots, we have: f(x) = (x - (-5))(x - (-2))(x - 0) = (x + 5)(x + 2)(x - 0) = (x + 5)(x + 2)(x).
Simplifying further, we get: f(x) = (x^2 + 7x + 10)(x) = x^3 + 7x^2 + 10x.
Therefore, the polynomial function of the lowest degree with -5, -2, and 0 as roots is f(x) = x^3 + 7x^2 + 10x.

A school is arranging a field trip to the zoo. The school spends 526.26 dollars on passes for 47 students and 2 teachers. The school also spends 401.38 dollars on lunch for just the students. How much money was spent on a pass and lunch for each student
The total amount of money spent on pass and lunch for each student is $19.28.
How much is spent on lunch and a pass?The first step is to determine the amount that was spent on a pass for each student. The cost of one pass can be determined by dividing the total amount spent on passes by the total number of teachers and students.
Cost of one pass = total amount spent on one pass / total number of people
Cost of one pass = 526.26 / (47 + 2)
Cost of one pass = 526.26 / 49
Cost of one pass = $10.74
The second step is to determine the amount spent on lunch for one student. This can be determined by dividing the total amount spent on lunch by the total number of students.
Cost of one lunch = total cost of lunch / total number of students
401.38 / 47 = $8.54
Total amount spent on pass and lunch for each student = cost of lunch for one student + cost of a pass for one student
$8.54 + $10.74 = $19.28

The hotel bill for a number of people for overnight stay is ₹4800. If there were 4 more the bill of each person had to pay would have reduced by ₹200. Find the number of people staying over night
Answer:
8
Step-by-step explanation:
Given hotel bill = ₹4800
Let initially, number of people = \(x\)
Initial Bill of each person = Hotel bill divided by number of people = \(\frac{4800}{x}\)
4 people are added to the hotel stay.
i.e. new number of people = \(x+4\)
New bill becomes ₹200 less for each person.
New bill for each person = \(\frac{4800}{x}\) - 200
Hotel bill remains the same i.e. ₹4800 = New bill for each person multiplied by new number of people.
\(4800 = (\dfrac{4800}{x}-200) (x+4)\\\Rightarrow 4800 = \dfrac{4800}{x}\times x -200\times x + \dfrac{4800}{x}\times 4 - 200\times 4\\\Rightarrow 4800 = 4800 -200 x + \dfrac{4800}{x}\times 4 - 800 \\\Rightarrow 800 = -200x+\dfrac{19200}{x}\\\Rightarrow 4 = -x+\dfrac{96}{x}\\\Rightarrow x^2+4x-96=0 \\\Rightarrow x^2+12x-8x-96=0\\\Rightarrow x(x+12)-8(x+12)=0\\\Rightarrow \bold{x = 8}, x= -12\ not\ possible\)

Give a counterexample to the false conditional statement "If two angles are supplementary, then one angle is acute
Step-by-step explanation:
When two angles add up and it is equal to 180 degrees, the angles are supplementary i.e.
A +B = 180
The angles that more than 0 degrees and less than 90 degrees, are acute angles and the angles that are more than 90 degrees but less than 180 are obtuse angles.
The statement is "If two angles are supplementary, then one angle is acute". It is somewhere true as well as false. It is true if and only angles are not equal to 90 degrees.
Take both angles as right angles. This is the only counterexample available if you don't count the angle in negative magnitude to show reverse direction(clockwise) angle measurement.
Definition of supplementary angles:
Two angles are supplementary if they add up to \(180^{\circ}\).
Definition of acute angle:
Angle which measures less than \(90^{\circ}\).
Now take two angles as of x and y degrees respectively.
Let x = y = 90 degrees.
Then both x and y angles are supplementary (as they add up to 180 degrees) yet they are not acute.
Hence shown.

In 2002, the mean expenditure for auto insurance in a certain state was $806. An insurance salesperson in this state believes that the mean expenditure for auto insurance is less today. She obtains a simple random sample of 32 auto insurance policies and determines the mean expenditure to be $781 with a standard deviation of $39.13. Is there enough evidence to support the claim that the mean expenditure for auto insurance is less than the 2002 amount at the α = 0.05 level of significance?
Answer:
No there is not enough evidence to support the claim that the mean expenditure for auto insurance is less than the 2002 amount at the α = 0.05 level of significance
Step-by-step explanation:
Sample Mean = μ1 = $806
Sample Mean = μ2 = $ 781
Standard Deviation= S= σ =39.13
n= 32
Confidence Interval = 95 %
α= 0.05
z∝=± 1.96
We state the null and alternative hypotheses as
H0: μ1 = $806 and Ha: μ1 ≠ $806 two sided tail test
z= μ1 -μ2/σ/√n
z= 806-781/ 39.13/√32
z= 806-781/ 39.13/5.6568
z=806-781/ 6.92
z= 25/6.92
z= 3.613
Z> z∝
3.613 > ± 1.96
No there is not enough evidence to support the claim that the mean expenditure for auto insurance is less than the 2002 amount at the α = 0.05 level of significance
6. Conider the ordered pair. (0,0) (1. 5,4. 5) (3,9) (4. 5,13. 5). Write two rule. One for the x term in the given ordered pair and one for the y term. Decribe the relationhip between the correponding term
The x term of the given ordered pairs follow an arithmetic sequence, with common difference of 1.5. The y term of the ordered pairs follow an arithmetic sequence, with common difference of 4.5.
The relationship between the corresponding terms can be described as a linear relationship, where y is a function of x, such that y = 4.5x.
Ordered Pair Rule and RelationshipThe relationship between the x and y terms can be determined by observing the change in the values between the ordered pairs. For example, the difference in x values between (0,0) and (1.5,4.5) is 1.5, and the difference in y values is 4.5. This pattern continues for all the other pairs, with the x term increasing by 1.5 and the y term increasing by 4.5 for each subsequent pair. This is consistent with an arithmetic sequence, where the difference between each term is constant.
Since the y values increase linearly with the x values, this suggests that the relationship between x and y can be modeled as a linear equation, y = 4.5x. This linear relationship is further confirmed by the fact that the ratio of the increase in the y term to the increase in the x term is constant, and equal to 4.5.
