The missing side length of quadrilateral A is 2 cm.

What is the missing length?

Similar figures have the same angle measures but different side lengths. The given squares in the image are similar shapes because they have four angles and four equal sides, even if the lengths of their sides differ.

From the image;

Quadrilaterals A:

Length = 2cm

Width = x

Quadrilaterals B:

Length = 4cm

Width = 4cm

Since the two quadrilaterals are similar, their corresponding sides are proportional.

Hence:

2/x = 4/4

Simplifying this proportion, we get:

2/x = 1

Multiplying both sides by x, we get:

2 = x

x = 2cm

Therefore, the missing length is 2 cm.

What is the sum of 17.25 and 1.725 , to the nearest integer?

Answers

The sum of 17.25 and 1.725, to the nearest integer, is 19.

First, let's add the two numbers together: 17.25 + 1.725 = 19.975

Next, we need to round the sum to the nearest integer. To do this, we need to look at the tenths place of the number. Since the tenths place is a nine, we need to round up to the nearest integer.

In this case, the nearest integer is 19.

To check our answer, we can add the two numbers together again using a calculator and confirm that the answer is 19.

To make sure we understand how to round to the nearest integer, let's look at another example. If we add 3.45 + 2.735, the sum is 6.185.

Looking at the hundredths place, we see that it is a five. Since five is greater than or equal to five, we need to round up to the nearest integer.

In this case, the nearest integer is 7.

To check our answer, we can add the two numbers together again using a calculator and confirm that the answer is 7.

In summary, to round a number to the nearest integer, we need to look at the tenths place. If the tenths place is greater than or equal to five, we round up to the nearest integer. If it is less than five, we round down to the nearest integer.

Therefore, the sum of 17.25 and 1.725, to the nearest integer, is 19.

a random sample x1,x2 ...,xn of size n is taken from a poisson distribution with a mean of λ, 0 < λ < [infinity]. (a) show that the maximum likelihood estimator for λ is bλ

Answers

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:

a = 4

b = 11

Step-by-step explanation:

To convert the recurring decimals into fraction we will follow the following process.

Given recurring decimal is 0.36363636....

Let x = 0.363636......... (1)

Multiply this decimal with 100.

100x = 36.36363636...........(2)

Now subtract expression (1) from expression (2)

100x = 36.363636.......

     x =   0.363636.......

99x = 36

x = \(\frac{36}{99}\)

x = \(\frac{4}{11}\)

Since, \(x=\frac{a}{b}=\frac{4}{11}\)

a = 4 and b = 11 will be the answer.

The sum of five consecutive multiples of 4 is 20.Find the smallest integer.

Answers

Answer:

The smallest integer is -4.

Step-by-step explanation:

Let the smallest integer be x.

Since the integers are all multiples of 4, they are

=> x, x+4, x+8, x+12 and x+16

=> x + x+4 + x+8 + x+12 + x+16 = 20

=> 5x + 40 = 20

Subtract 40 from both sides of the equation

5x +40 - 40 = 20 - 40

5x = -20

Divide both sides by the coefficient of x(which is 5)

\(\frac{5x}{5} = \frac{-20}{5}\)

x = -4

∴ the smallest integer is -4.

use f(x, y, z) = x2 yz, f(x, y, z) = xy, yz, xz , and g(x, y, z) = −sin(z), exz, y . compute (f ✕ g)(2, −1, 5). (your instructors prefer angle bracket notation < > for vectors.)

Answers

Using (f ✕ g)(2, -1, 5) we get the value <2 + 5e^10, -5sin(5) + 20, 20sin(5) - 2e^10> for vectors.

To compute (f ✕ g)(2, -1, 5), we need to take the cross product of the vectors f(2, -1, 5) and g(2, -1, 5).

First, let's find the vector f(2, -1, 5):

f(2, -1, 5) = (f1(2, -1, 5), f2(2, -1, 5), f3(2, -1, 5))

= (f1(2, -1, 5), f2(2, -1, 5), f3(2, -1, 5))

= (f1(2, -1, 5), f2(2, -1, 5), f3(2, -1, 5))

= (2^2 * (-1) * 5, 2 * (-1), (-1) * 5)

= (-20, -2, -5)

Next, let's find the vector g(2, -1, 5):

g(2, -1, 5) = (-sin(5), e^(2 * 5), -1)

= (-sin(5), e^10, -1)

Now, we can take the cross product of the vectors:

(f ✕ g)(2, -1, 5) = (-20, -2, -5) ✕ (-sin(5), e^10, -1)

To compute the cross product, we can use the determinant method:

(f ✕ g)(2, -1, 5) = <((-2) * (-1) - (-5) * e^10), (-5 * (-sin(5)) - (-20) * (-1)), (-20 * (-sin(5)) - (-2) * e^10)>

= <(2 + 5e^10), (-5sin(5) + 20), (20sin(5) - 2e^10)>

Therefore, (f ✕ g)(2, -1, 5) = <2 + 5e^10, -5sin(5) + 20, 20sin(5) - 2e^10>.

a store notices that a particular item in stock is never sold. this item could potentially make the store $7,142 daily, so the store manager begins an advertising campaign. on day 10 of the campaign, the store makes $1,295 in sales of this item. assume the increase in sales follows the pattern of newton's law of cooling (heating). how many days of campaigning will it take for the store to make at least $5,810 from a single day of sales of this item?

Answers

Newton's Law of Cooling is typically used to model the temperature change of an object over time, and it may not be directly applicable to modeling the increase in sales over time in this context.

However, we can make some assumptions and use a simplified approach to estimate the number of days required to reach a certain sales target.

Let's assume that the increase in sales follows an exponential growth pattern. We can use the formula for exponential growth:

P(t) = P₀ * e^(kt)

Where P(t) is the sales at time t, P₀ is the initial sales, k is the growth rate, and e is the base of the natural logarithm.

Given that on day 10, the sales are $1,295, we can write:

1,295 = P₀ * e^(10k)

Similarly, for the desired sales of $5,810, we have:

5,810 = P₀ * e^(nk)

To find the number of days required to reach this sales target, we need to solve for n.

Dividing the two equations, we get:

5,810 / 1,295 = e^(nk - 10k)

Taking the natural logarithm on both sides:

ln(5,810 / 1,295) = (nk - 10k) * ln(e)

Simplifying:

ln(5,810 / 1,295) = (n - 10)k

Now, if we have an estimate of the growth rate k, we can solve for n using the natural logarithm. However, without knowing the growth rate or more specific information about the sales pattern, we cannot provide an exact answer.

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

An equation is given which is :

y + 5 = \(\frac{3}{4}\) ( x - 12)

4y + 20 = 3x - 36

or

4y = 3x - 56        -- -- -- -- --- ---- ----- ----- --- --- --- Equation 1

We know that the slope intercept form of a line is given by :

y = mx + c

So , to change the above equation into slope intercept form we must divide equation 1 by 4. So , the rearranged equation will be :

4y / 4 = (3/4 x ) - (56 / 4)

y = \(\frac{3}{4}\) x + (-14)
