May someone please help me?I’m so confused.

Answer:

If each of the dimensions was enlarged by 3 units then the new length would be 5 and the new width would be 6. To find the area of the triangle we use the formula: A = L x W ÷ 2.


6 x 5 = 30ft2
30 ÷ 2 = 15ft2


Therefore the new area of the triangle would be 15ft2.

To find the maximum likelihood estimator (MLE) for λ, we need to maximize the likelihood function L(λ) with respect to λ of the Poisson distribution

First, let's write the probability density function (PDF) of the Poisson distribution:
P(X = k) = (e^(-λ) * λ^k) / k!

The likelihood function can be defined as the product of the probabilities for each observation in the random sample. Since the sample is independent and identically distributed, we can write the likelihood function as:
L(λ) = P(x1, x2, ..., xn | λ) = P(x1 | λ) * P(x2 | λ) * ... * P(xn | λ)

Taking the logarithm of the likelihood function (log-likelihood) will simplify the calculations. The log-likelihood function is:
log(L(λ)) = log(P(x1 | λ)) + log(P(x2 | λ)) + ... + log(P(xn | λ))

Now, let's calculate the derivative of the log-likelihood function with respect to λ:
d/dλ log(L(λ)) = d/dλ (log(P(x1 | λ)) + log(P(x2 | λ)) + ... + log(P(xn | λ)))
= d/dλ (log(P(x1 | λ))) + d/dλ (log(P(x2 | λ))) + ... + d/dλ (log(P(xn | λ)))

To find the MLE, we set the derivative equal to zero and solve for λ:
d/dλ log(L(λ)) = 0

The derivative of log(P(x | λ)) with respect to λ can be calculated using the logarithmic differentiation technique. After taking the derivative, we equate it to zero and solve for λ.

By solving the equation, we will obtain the MLE for λ.

Answer:

Victors pizza

Step-by-step explanation:

Peter paid 45 for 3 pizzas if we divide that it gives us 15 for each pizza

George paid 32 for 2 pizzas which if we divide it 16 for each pizza

Finally for Victor we just divide 135 by 8 and that gives us 16.875 for each pizza.

If we compare those values the highest is for sure Victors at 16.875 or 16.88 per pizza.

The repeating decimal 0.418 as a geometric series, we can express it as:
0.418 = 4 * 10^(-1) + 1 * 10^(-2) + 8 * 10^(-3) + 4 * 10^(-4) + 1 * 10^(-5) + 8 * 10^(-6) + ...
Now, we can rewrite it as a sum of an infinite geometric series:
0.418 = Σ[ (4 * 10^(-1))^n + (1 * 10^(-2))^n + (8 * 10^(-3))^n ] for n = 0 to ∞
This geometric series representation of the repeating decimal 0.418 can be used to perform various calculations and analyses.

To write the repeating decimal 0.418 as a geometric series, we can use the formula for the sum of an infinite geometric series:
S = a / (1 - r)
where S is the sum of the series, a is the first term, and r is the common ratio.

In this case, we can see that the repeating part of the decimal is 0.18. So we can write:
0.418 = 0.4 + 0.01(8 + 0.008 + 0.00008 + ...)
where we've broken up the repeating part into a sum of infinitely many terms, each with a smaller power of 10.

Now we can see that the first term of this series is 0.01 (since that's coefficient of the first term in the repeating part), and the common ratio is also 0.01 (since each term is 1/10th of the previous term). So we have:
a = 0.01
r = 0.01

Plugging these values into the formula for the sum of an infinite geometric series, we get:
S = 0.4 + 0.01 / (1 - 0.01) = 0.4 + 0.01 / 0.99

Simplifying this expression, we get:
S = 0.4 + 0.01010101...
which we recognize as another repeating decimal, with repeating part 0.01. So we can write:
S = 0.4 + 0.01(S)
where S is the sum of the series. Solving for S, we get:
S = 0.4 / (1 - 0.01) = 0.404

So the repeating decimal 0.418 can be written as the geometric series:
0.418 = 0.4 + 0.01(8 + 0.008 + 0.00008 + ...)
      = 0.4 + 0.01(S)
      = 0.404 + 0.00010101...

Total amount of money in the account in the second bank after 3 years will be represented by the function: P\(e^{0.0747}\).

The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-

A = P\(e^{rt}\)

Here, we are given that there are 2 financial institutions-

1st financial institution:

interest rate =  3% for the first year

and interest rate for next two years = 2%

2nd Financial institution:

interest rate = 2.49% for three years

Let the principal amount deposited be P

We assume that the interest is compounded continuously.

Then for the 2nd bank-

Amount = P\(e^{rt}\)

here, r = 2.49%

= 0.0249

Amount = P\(e^{0.0249 * 3}\)

= P\(e^{0.0747}\)

Thus, the total amount of money in the account in the second bank after 3 years will be given by the function- P\(e^{0.0747}\).

Naive Bayes works based on the idea that Predictor variables in the ML process is independent of each other.What is Naive Bayes?Naive Bayes is a classification technique used in machine learning.

This is based on Bayes' theorem, which describes the probability of a hypothesis given prior knowledge. This algorithm is called "naive" because it makes the assumption that all of the predictor variables are independent of each other.In other words, each predictor variable has an equal effect on the outcome. As a result, it may be necessary to reduce the number of predictor variables to get a more accurate model. However, Naive Bayes is effective when the number of predictors is high and the correlation between them is low.

The frequencies of the three genotypes in the population of flies are:

f(ee) = 0.4 or 40%

f(Ee) = 0.3 or 30%

f(EE) = 0.3 or 30%

In a population of organisms, the frequencies of different genotypes can be calculated based on the number of individuals that have each genotype. In this case, we are given the number of flies that have each genotype, and we can use this information to calculate the frequencies of the three genotypes.

The frequencies of the three genotypes can be calculated as follows:

Total number of flies = 200 + 150 + 150 = 500

f(ee) = (number of ee flies) / (total number of flies) = 200/500 = 0.4 or 40%

f(Ee) = (number of Ee flies) / (total number of flies) = 150/500 = 0.3 or 30%

f(EE) = (number of EE flies) / (total number of flies) = 150/500 = 0.3 or 30%

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

The function f(x) = { (1/16)x³, x ≤ 4; x² + 4, x > 4 } is differentiable everywhere, since it is continuous and has a well-defined derivative at every point and the value of a is 1/16 and b is 4

Now, let's consider the function f(x) given by f(x) = { ax^3, x ≤ 4; x^2 + b, x > 4 }. We are asked to find values for a and b such that the function is differentiable everywhere.

Returning to our function f(x), we need to find values for a and b such that the left and right limits of f(x) at x = 4 are equal and are equal to the value of f(x) at x = 4.

The left limit of f(x) at x = 4 is given by:

lim (x → 4-) f(x) = lim (x → 4-) (ax³) = 64a

The right limit of f(x) at x = 4 is given by:

lim (x → 4+) f(x) = lim (x → 4+) (x² + b) = 16 + b

The value of f(x) at x = 4 is given by:

f(4) = 64a = 16 + b

To make the left and right limits equal, we must have:

64a = 16 + b

To make the function continuous at x = 4, we must have:

64a = 16 + b = f(4)

Solving for a and b, we get:

a = 1/16

b = 4
