Say you have a single pair of pants and a single shirt. In this case you'd only have 1 outfit option.

If you have 2 pairs of pants and 2 shirts, you now have 4 unique outfit options.

How many pairs of pants and shirts would you need in order to have a unique outfit for each day of the week?

What if you wanted a unique outfit each day for a month? for a year? for your whole life

Answer:

The answer is A

Step-by-step explanation:

The equation of the nth term is a(n) = 2-8n

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression.

The common difference = -14-(-6) = -14 +6 = -8

The first term is a1

The nth term of an arithmetic sequence =

a(n )= a1+(n-1)d

a(n) = a1+(n-1)-8

a(n )= a1-8n+8

if a1 = -6

a(n) = -6-8n +8

a(n) = 2-8n

therefore the nth term of the sequence is 2-8n

What is percentage ?

A percentage is a way of expressing a number as a fraction of 100. The symbol for percentage is "%". For example, 50% means 50 out of 100 or 0.5 as a decimal.

Percentages are commonly used to represent proportions, rates, and changes in quantities. They can be used to compare quantities of different sizes, or to express how much one quantity has changed relative to another quantity.

According to the question:
To predict the population of the city in 2020, we can use the formula:

P = P₀(1 + r)ᵗ

where:

P₀ = the initial population (in 2000) = 2000

r = the annual growth rate as a decimal = 0.02

t = the number of years since the initial population = 20 (since we want to predict the population in 2020, which is 20 years after 2000)

Substituting these values into the formula, we get:

P = 2000(1 + 0.02)²⁰

Using a calculator, we can simplify this to:

P ≈ 2930.63

Therefore, we can predict that the population of the city in 2020 will be approximately 2931 (rounded to the nearest whole number).

The perimeter of triangle ΔCBH found using the relationship between similar triangles, ΔCBH, and ΔFEH is 18.9

Similar triangles are triangles that have the same shape and interior angles and between which the ratio of their corresponding sides are equivalent.

The specified parameters are;

The triangles ΔCBH and ΔFEH are similar, ΔCBH ~ ΔFEH

The alternate interior angles theorem indicates that we get;

∠BCH is congruent to ∠EFH and ∠CBH is congruent to ∠FEH

Vertical angles theorem, indicates that we get;

∠CHB ≅ ∠FHE

The ratio of the corresponding sides formed between similar triangles are equivalent, therefore, we get;

CH/FH = BH/EH

7/10 = BH/6

BH = 6 × (7/10) = 4.2

BH = 4.2

CH/FH = BC/EF

7/10 = BC/11

BC = 11 × 7/10 = 7.7

BC = 7.7

The perimeter of the triangle ΔCBH = BC + BH + CH

Therefore, the perimeter of ΔCBH = 7.7 + 4.2 + 7 = 18.9

The speed of the wind is 60 mph.

Let's denote the speed of the wind as r. When the plane is flying with the wind, its speed is (360 + r) mph, and when it's flying against the wind, its speed is (360 - r) mph.

According to the question, the plane flew the same distance with and against the wind, so we can set up an equation:

2.5(360 + r) = 3.5(360 - r)

Expanding the equation, we get:

900 + 2.5r = 1260 - 3.5r

Simplifying and rearranging the terms, we get:

6r = 360

Dividing both sides of the equation by 6, we get:

r = 60

The formula for percentage error in physics is:

% error = (|experimental value - accepted value| / accepted value) x 100%

In this formula, the experimental value is the measured value obtained from an experiment, the accepted value is the true or theoretical value, and the absolute value of the difference between them represents the error. Dividing this error by the accepted value and multiplying by 100% gives the percentage error.

The percentage error is used to assess the accuracy of experimental measurements and to determine the degree of deviation between the experimental and accepted values. The lower the percentage error, the more accurate the measurement is considered to be.

" Stefan spend originally $120. 180-120=60

He make $60 by selling the bicycle and helmet to Jin.

There are 2.19,  39 euros in $100.

To determine how many 39 euros are equivalent to $100, you need to know the current exchange rate between euros and US dollars. The exchange rate varies constantly, so it's important to use the most up-to-date rate.

As of the time of writing, the exchange rate is 1 euro = 1.17 US dollars. This means that for every euro, you get 1.17 US dollars.

To determine how many 39 euros are equivalent to $100, you can use the following formula:

39 euros * (1.17 US dollars/1 euro) = X US dollars

Simplifying the equation gives:

45.63 US dollars = X US dollars

So, 39 euros are equivalent to 45.63 US dollars. To determine how many 39 euros are equivalent to $100, you can use the following formula:

$100 / (1.17 US dollars/1 euro) = X euros

Simplifying the equation gives:

85.47 euros = X euros

So, 85.47 euros are equivalent to $100. Therefore, you would need approximately 85.47/39 = 2.19 sets of 39 euros to reach $100.

Forty-seven and seven tenths minus twenty-three and nineteen-hundredths is equal to twenty-four and fifty-one hundredths, or 24.51 as a decimal.

To find the difference between forty-seven and seven tenths (47.7) and twenty-three and nineteen hundredths (23.19), we can simply subtract the two numbers using the standard subtraction method for decimals. Here are the steps:
1. Line up the decimals:
47.70
-23.19
2. Subtract the hundredths place: 0 - 9 = -9. Since we can't have a negative number in the hundredth place, we need to borrow 1 from the tenths place. So, 10 - 9 = 1.
3. Subtract the tenths place: 6 (after borrowing) - 1 = 5.
4. Subtract the ones place: 7 - 3 = 4.
5. Subtract the tens place: 4 - 2 = 2.
So, the final answer is 24.51.

Mean 4.9 letters and standard deviation 1.5 letters are best estimates of the population parameters . So, the correct option is (C)

The estimated mean of the sampling distribution is 4.9 letters, which is a good estimate of the population mean word length. The estimated standard deviation of the sampling distribution is 0.15 letter, which is the standard error of the mean.

The standard error of the mean is calculated by dividing the population standard deviation by the square root of the sample size. Since the sample size is 100 and the standard error is 0.15 letter, we can estimate the population standard deviation as follows:

population standard deviation = standard error x sqrt(sample size)

= 0.15 x sqrt(100)

= 1.5 letters

Therefore, the best estimates of the population parameters are:

Mean = 4.9 letters (same as the estimated mean of the sampling distribution)

Standard deviation = 1.5 letters
