Answer 1

Step-by-step explanation:

so, for (4, 8) × 1/4, what is 4×1/4 ? and what is 8×1/4 ?

(1, 2)

similar for (4, -8) it is (1, -2).

similar for (-8, 0) it is (-2, 0).

similar for (8, 0) it is (2, 0).

that's it. that's really all there is to it. you multiply all the coordinates by the scale factor.

we have discussed four tree-based methods: decision trees, bagging, random forests, and boosting. which approach relies on bootstrapped samples, i.e., taking repeated random samples with replacement from the training data? check all that apply.

Answers

The correct answer is boosting.

Given that,

The four tree-based techniques are boosting, bagging, random forests, and decision trees. Which method uses bootstrapped samples, or the process of repeatedly obtaining random samples from training data and replacing them?

Boosting is an emsemble machine learning approach, where we use bootstrapping sampling technique to get the required samples. It helps in the reduction of variance and thus bring in less bias in the sampling approach. Therefore boosting is the correct answer here.

In order to gather the necessary samples for boosting, we employ the bootstrapping sampling technique. It aids in lowering variance, which reduces bias in the sampling strategy. Thus, boosting is the appropriate response in this case.

Answers

The value of a in the equation is 32/81

How to determine the value of a

From the question, we have the following parameters that can be used in our computation:

log2 ab = 5 and log3 b = 4

Rewrite the above equations properly

So, we have the following representations

log₂ ab = 5 and log₃ b = 4

Apply the exponent law of logarithm

This gives

ab = 2⁵ and b = 3⁴

Divide both equations

So, we have the following representation

ab/b = 2⁵/3⁴

Evaluate the quotient

a = 32/81

Hence, the value of a is 32/81

There are some nickles, dimes, and quarters in a large piggy bank. For every 2 nickles there are 3 dimes. For every 2 dimes there are 5 quarters. There are 500 coins total.

1. How many nickles, dimes, and quarters are in the piggy bank? Explain.

2.How much are the coins worth?

Answers

1. There are 80 Nickels, 120 dimes, and 300 quarters in the piggy bank.

2. The coins worth is $91

How many types of coins are there?

There are 4 types of coins. They are Quarter, Nickel, dime, and Penny.

1 Quarter = 25 cent

1 dime = 10 cents

1 Nickel = 5 cents

1 penny = 1 cent

Assume that, the number of Nickel coins is x.

Given that, 2 nickles there are 3 dimes.

1 nickle there are 3/2 dimes.

x nickles there are 3x/2 dimes.

Also given that,

2 dimes there are 5 quarters.

1 dimes there are 5/2 quarters.

3x/2 dimes there are (5/2) × (3x/2) quarters = 15x/4.

There is 500 coins in the piggy.

Therefore, x + (3x/2) + (15x/4) = 500

(4x + 6x + 15x) /4 = 500

25x/ 4 = 500

x = 80.

The number of dimes is (3 × 80)/2 = 120

The number of quarters is (15 × 80)/4 = 300.

The total cost of 80 nickles, 120  dimes, and 300 quarters is

= [(80 ×  5) + (120 × 10) + (300 × 25)] cents

= 400 + 1200 + 7500 cents

= 9100 cents

= $(9100/100)

what is the probability that the lifetime of at least one component exceeds 5? (do not round intermediate values. round your answer to three decimal places.)

Answers

Therefore, the probability that the lifetime X of the first component exceeds 5 is 0.006737, based on process.

What is probability?

Probability theory examines numerical illustrations of the probability that an event will happen or that a statement is true. An event's probability is expressed as a number between 0 and 1, with 1 generally denoting certainty and 0 generally denoting impossibility.

Here,

f(x,y) =[tex]xe^{-x(1+y)}[/tex]

Took the double integral of the equation above, first the integral with respect to y (from 0 to infinity) and then with respect to x (from 5 to infinity).

therefore the integration,

[tex]\int\limits^ {infinity}_0{xe^{-x(1+y)} } \, dx[/tex]

[tex]\left \{ {{y=infinity} \atop {x=0}} \right. \frac{-x}{y+1} e^{-x(y+1)} + \frac{1}{y+1} \int\limits^{infinity} _0{ e^{-x(y+1)} \, dx[/tex]

[tex]=\frac{1}{(y+1)^2}[/tex]

[tex]fX(x)[/tex] is easier with:fX(x) =[tex]\int\limits^{infinity}_0 {x}e^{-(x(y+1))} \, dy[/tex]=[tex]xe^{-x} \int\limits^{infinity}_0 x {e^{-xy} } \, dy=e^{-x}[/tex]

We get

We used u substitution to end up with    [tex]e^{-x(1+y)}[/tex] which is needed to evaluate from 0 to infinity, which left me with [tex]e^{-x}[/tex]

Then the integral with respect to x from 5 to infinity which left with an answer of [tex]e^{-5}[/tex]

So the probability that the lifetime X of the first component exceeds 5 is 0.006737, based on my process.

In this problem, the middle coefficient is 5. Find what numbers multiply together to have a product of 6, and add together to have a sum of 5.The numbers +2 and +3 multiply together to have a product of 6, and add together to have a sum of 5.

How do you convert 2 as a percentage?

The way you worded your question is a little unclear, so I’ll do my best to cover both possible interpretations.

Converting anything from a decimal to a percentage means dividing it by 100. Assuming your percentage is 2%, your decimal would be 0.02. If you mean your decimal is 2, your percentage would do the opposite of dividing by 100 which is multiplying by 100. Therefore if your decimal was 2, your percentage would be 200%

What is Total Revenue?

Total revenue is the overall sum of money received by a business through the sale of its products and services. Based on demand and price, it measures how successfully a company is generating revenue from its main operations.

Let x - normal (101.15 ,12.15)

where µ = 101.15

σ = 12.15

Mean for 85 customers

µ = 85 * 101.15 =8597.75

standard deviation for 85 customers

σ = [tex]\sqrt{85}[/tex] * 12.15 = 112.017

P ( x >x₁ ) = 0.05

P ( x-µ/ σ > x₁-8597.75/112.017) = 0.05

P (Z >Z₁) = 0.05

Where

Z₁ = x- 8597.75/112.017

Z₁ = 1.645

What is equation?

Equations are logical statements in mathematics with two algebraic expressions on either side of the equals (=) symbol. The expressions on the left and right are demonstrated to be equal in relation to one another. All mathematical equations start with LHS = RHS (left hand side = right hand side). To find the value of an unknown variable, or unknown quantity, you can solve equations. If the statement does not contain an "equal to" sign, it is not an equation. As an expression, it will be considered. An explanation of the differences between an expression and an equation will be provided later in this essay.

Here,

P=850+5x

so the band’s goal is for the amount earned on ticket sales minus production costs to equal $5,000 per concert.

So new equation formed is

50x-P=5000

50x-(850+5x)=5000

50x-5x-850=5000
