John always wears a shirt, pants, socks, and shoes. He owns 12pairs of socks, 3 pairs of shoes, 5 pairs of pants, and 5 shirts. How many different outfits can John make?
Step-by-step explanation:
John always wears a shirt, pants, socks, and shoes. He owns 12 pairs of socks, 3 pairs of shoes, 5 pairs of pants, and 5 shirts.
For example If John has 2 pants and 3 shirts
he make an combination of 1 pant with 3 shirts
and another pant with 3 shirts
so total of 6 combination he can make (2*3)= 6
To find the number of combination we multiply all the shirt, pants, socks, and shoes he have
12pairs of socks, 3 pairs of shoes, 5 pairs of pants, and 5 shirts.
12 * 3 * 5 * 5 = 900
So 900 different combination John can make
Combination helps us to find a number of ways. The number of ways John can wear an outfit is 900.
What is the Combination?A combination helps us to find the number of ways something can be selected from a set. It is given by the formula,
[tex]^nC_r = \dfrac{n!}{r!(n-r) ! }[/tex]
where n is the total number of choices in the set, r is the number of choices we want.
Given to us
Number of pairs of socks = 12
Number of pairs of shoes = 3
Number of pants = 5
Number of shirts = 5
The number of ways John can wear an outfit can be found out using the combination of shirt, socks, pants, and shoes. Therefore,
Number of ways John can wear an outfit
= Number of ways John wears shocks x Number of ways John wears shoes x Number of ways John wears pants x Number of ways John wears a shirt
Number of ways John can wear an outfit
[tex]= ^{12}C_1 \times ^{3}C_1 \times ^{5}C_1 \times ^{5}C_1 \\[/tex]
= 900
Hence, the number of ways John can wear an outfit is 900.

Be independent uniform random variables on [0, 1], and let u(n) be the maximum find the cdf of u(n) and a standardized u(n), and show that the cdf of the standardized variable tends to a limiting value.
The cumulative distribution function (CDF) of u(n), when u(n) is the maximum of n independent uniformly-distributed random variables, is given by x^n. After standardization, as n approaches infinity, the CDF of the standardized variable converges to a standard normal distribution, as per the central limit theorem.
Explanation:The subject matter relates to the field of statistics, specifically dealing with the concept of uniform distribution and standard normal distribution.
Let's denote the random variables as X1, X2, ..., Xn and they are uniformly distributed over [0, 1].Given that u(n) is the maximum of these random variables, the cumulative distribution function (CDF) of u(n) can be calculated as follows:
P(u(n) < x) = P(X1 < x, X2 < x, ..., Xn < x) = P(X1 < x) * P(X2 < x) * ... * P(Xn < x) = x^n
Given that Z = (u(n) - μ) / σ where μ is the mean and σ is the standard deviation. For the uniform distribution, μ = 0.5 and σ = √ (b - a)² / 12 = √1 / 12. Therefore, the standardized random variable Z can be calculated.
By the central limit theorem, as n increases, the standardized variable tends to a limiting value. Which means as n -> ∞ , the cumulative distribution function of Z = 1, the standardized variable converts to a standard normal distribution, and it poses bell-shaped curve form.

If an asset declines in value from $5000 to $3500 over nine years, what is the mean annual growth rate in the asset's value over these nine years? Round your answer to two decimal places.
Mean annual growth rate in the asset’s value over the nine years is -3.8856%.
Given that an asset declines in value from $5000 to 3500 over the nine years.
To determine the mean growth rate over some period of time, compute the geometric mean of the growth factors. A growth factor less than one indicate negative growth.
The formula for the geometric mean over n periods is given by
[tex]y_n =\sqrt[n]{ {y_1 \times y_2 \times y_3 \times ......\times y_n}}[/tex]
Suppose an asset declined over nine years.
[tex]3500 = 5000\times({y_1 \times y_2\times y_3 \times ..\times y_9})[/tex]
[tex]{y_1 \times y_2\times y_3 \times ..\times y_9} = 3500/5000\\\ y_1 \times y_2\times y_3 \times ..\times y_9} = 0.7[/tex]
Then, the mean annual growth factor over these nine years is,
[tex]y_9 = \sqrt[9]{0.7}[/tex]
= 0.961144
Compute the mean annual growth rate in the asset’s value.
= (0.961144 - 1) 100%
= -3.8856%
Therefore, the mean annual growth rate in the asset’s value is -3.8856%.

To find the mean annual growth rate of an asset declining from $5000 to $3500 over 9 years, you calculate the growth rate 'r' using the formula P(t) = P0 * e^(rt). The result is about -5.13%, indicating a depreciation in the asset's value.
Explanation:To calculate the mean annual growth rate for an asset that declines in value, we can use the formula for the annual growth rate, which is P(t) = P0 * e(rt), where:
P(t) is the future value of the asset.P0 is the initial value of the asset.e is the base of the natural logarithm.r is the growth rate.t is the time in years.In this case, the value of the asset declines from $5000 to $3500 over 9 years. Therefore, we have:
P0 = $5000P(t) = $3500t = 9 yearsFirst, we need to solve for r in the equation:
3500 = 5000 * e(9r)
By dividing both sides by 5000 and taking the natural logarithm, we get:
ln(3500/5000) = ln(e(9r))
ln(0.7) = 9r
r = ln(0.7)/9
Substitute the value of ln(0.7) and divide by 9:
r = -0.0512932942
Since the result is negative, it indicates a decline, and the annual growth rate is about -5.13%, reflecting a decrease in value.

8x+10y
Answer has been edited.
Answer:
Subtract (4x − 3y) from the sum of (12x + 9y) and (−2y) is 8x + 10y .
Step-by-step explanation:
As given the expression
(12x + 9y) , (-2y) and (4x − 3y) .
First add the expression (12x + 9y) and (-2y) .
= (12x + 9y) - (2y)
First open the bracket
= 12x + 9y - 2y
= 12x + 7y
Now subtracted (4x − 3y) from 12x + 7y .
= 12x + 7y - (4x - 3y)
= 12x - 4x + 7y + 3y
= 8x + 10y
Therefore the Subtract (4x − 3y) from the sum of (12x + 9y) and (−2y) is 8x + 10y .
How many ways can first, second, and third place be assigned?At a gymnastics meet, twenty gymnasts compete for first, second, and third place.
The total number of ways can first, second and third place can be assigned are:
6840
Step-by-step explanation:The total number of people that compete are: 20
Out of these 20 people we have to chose 3 people and also arrange them according to their ranks.
We know that when we have to choose and arrange r items out of total n items then we need to use the method of permutation.
Hence, the formula is given by:
[tex]n_P_r=\dfrac{n!}{(n-r)!}[/tex]
Here we have:
n=20 and r=3
Hence, the number of ways first, second and third place can be assigned are:
[tex]{20}_P_3=\dfrac{20!}{(20-3)!}\\\\\\{20}_P_3=\dfrac{20!}{17!}\\\\\\{20}_P_3=\dfrac{20\times 19\times 18\times 17!}{17!}\\\\\\{20}_P_3=20\times 19\times 18\\\\\\{20}_P_3=6840[/tex]
