The values of x and y the triangles to the fight congruent are x = 3 and

y = 1.

What is congruent triangles?

Triangles with the same size and shape are said to be congruent. This implies that the corresponding sides and angles are both equal. Without comparing every angle and side of the two triangles, we can determine whether two triangles are congruent.

If given these triangles are congruent then all corresponding side must be equal

As we can see that both triangle are right triangle

Therefore hypotenuse of one triangle equal to another

x+1  = 4y   ..... (A)

And lenght ( height)  of one  must equal to another triangle

x = y +2          .... (B)

therefore

Plug the value of x = y + 2 in equation A

y + 2 + 1 = 4y

        3y = 3

          y = 1

and x = y+2

x = 1 + 2

x = 3

Hence, the values of x and y the triangles to the fight congruent are

Answer:

\( C = \dfrac{5}{9}(F - 32) \)

Step-by-step explanation:

\( F = \dfrac{9}{5}C + 32 \)

Switch sides to have C on the left side.

\( \dfrac{9}{5}C + 32 = F \)

Subtract 32 from both sides.

\( \dfrac{9}{5}C = F - 32 \)

Multiply both sides by 5/9.

\( \dfrac{5}{9} \times \dfrac{9}{5}C = \dfrac{5}{9} \times (F - 32) \)

The answer you've chosen is correct: 14.91cm

Step-by-step explanation:

The volume of the octahedron is 4000 cubic centimeters.

To find the volume of the octahedron, we'll first find the volume of one pyramid and then multiply it by 2 since the octahedron is made up of two pyramids.

Step 1: Find the height of one pyramid.
Since the overall height of the octahedron is 30 cm and it's made up of two pyramids of equal height, the height of one pyramid is 30 cm / 2 = 15 cm.

Step 2: Calculate the volume of one pyramid.
The formula for the volume of a pyramid is (1/3) * base_area * height.
In this case, the base is a square with sides measuring 20 cm, so the base area is 20 cm * 20 cm = 400 cm².

Step 3: Apply the formula.
Volume of one pyramid = (1/3) * 400 cm² * 15 cm = 2000 cm³.

Step 4: Find the volume of the octahedron.
Since the octahedron consists of two identical pyramids, we'll multiply the volume of one pyramid by 2.
Volume of octahedron = 2 * 2000 cm³ = 4000 cm³.

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, it is true that 95% of the coworkers fall within the interval (0.339, 0.501), and we can be 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%. However, it is false to say that there is a 95% chance that a randomly selected coworker has received the vaccine or that there is a 42% chance for a randomly selected coworker to have received the vaccine.

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, we can determine which of the following statements are true:

a) 95% of the coworkers fall in the interval (0.339, 0.501).

This statement is true. The 95% confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that 95% of the coworkers fall within the interval (0.339, 0.501).

b) We are 95% confident that the proportion of coworkers who have received this year's flu vaccine is between 33.9% and 50.1%.

This statement is true. The 95% confidence interval (0.339, 0.501) provides us with a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that we are 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%.

c) There is a 95% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 95% confidence interval does not represent a probability or chance for an individual coworker. It provides a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. It does not give information about the likelihood of an individual coworker receiving the vaccine.

d) There is a 42% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 42% represents the proportion of coworkers in the survey who have received the flu vaccine, but it does not represent the chance or probability for a randomly selected coworker to have received the vaccine. The 42% is a point estimate, not a probability.

e) We are 95% confident that between 33.9% and 50.1% of the samples will have a proportion near 42%.

This statement is false. The confidence interval (0.339, 0.501) does not directly provide information about the proportion of samples that will have a proportion near 42%.

a) p(x=2) = 0.25

b) E(X) = 2.15

a) To find p(x=2), we simply look at the probability distribution table and find the probability associated with x=2. In this case, we see that the probability associated with x=2 is missing, but we know that the sum of all probabilities must equal 1. Thus, we can solve for p(x=2) by subtracting the sum of the probabilities associated with x=0, x=1, x=3, and x=4 from 1. This gives us:

p(x=2) = 1 - 0.1 - 0.4 - 0.15 - 0.1

p(x=2) = 0.25

b) To find E(X), we use the formula:

E(X) = Σ[x * p(x)]

where Σ is the summation symbol, x is the value of the random variable, and p(x) is the probability associated with that value. Applying this formula to the probability distribution given, we have:

E(X) = 0(0.1) + 1(0.4) + 2(p(x=2)) + 3(0.15) + 4(0.1)

E(X) = 0.4 + 0.3 + 0.15 + 0.4

E(X) = 2.15

Therefore, the expected value of X is 2.15.

Hello-

6² + (y - x) is our equation. And wonder of wonders, our x and y values are given! What a beautiful thing, having both given to us.

x = -5

y = -77

Let's plug our given values into our equation for x and y. Like so-

6² + (y - x) becomes 6² + (-77 - (-5))

In math, we must do whatever operations are contained within parentheses first and foremost. So we must subtract -5 from -77. That, by the way, equals -72.

6² + -72

Now we do our exponents, or powers.

6² = 36

36 + -72

Now we do the easiest part - adding.

32 + -72 = -36

So the answer to this problem (if I've done my algebra correctly) is -36.

Bob should use a sub-sampling factor of approximately 2.089 to reduce the audio file size from 94 MB to 45 MB.

To determine the sub-sampling factor Bob should use, we need to consider the file size reduction required from 94 MB to 45 MB.

Let's assume the audio file has a constant bit rate. In that case, we can estimate the reduction factor by comparing the file sizes. The ratio of the file sizes will approximate the ratio of the audio durations.

The initial file size is 94 MB, and Bob wants to reduce it to 45 MB. Therefore, the reduction factor can be calculated as follows:

Reduction Factor = Desired File Size / Initial File Size

= 45 MB / 94 MB

≈ 0.4787

This reduction factor can be used to estimate the sub-sampling factor. Since the duration of the audio is directly proportional to the file size, we can assume that reducing the audio duration by the same factor will result in the desired file size reduction.

Sub-sampling Factor = 1 / Reduction Factor

≈ 1 / 0.4787

≈ 2.089

Therefore, Bob should use a sub-sampling factor of approximately 2.089 to reduce the audio file size from 94 MB to 45 MB.

The time-series model that assumes that demand in the next period will be equal to the most recent period's demand is A) Naive approach.

This model is based on the simplest assumption of all, that the next period's demand will be equal to the current period's demand. It is called the naive approach because it assumes no underlying pattern in the data and provides a baseline prediction. The formula for the naive approach is as follows:

y(t) = y(t-1) where y(t) represents the demand in period t and y(t-1) represents the demand in the previous period.

Although this model is simple, it is often used as a benchmark for comparison with more complex models and can provide reasonable results for stable demand patterns.

The correct statement is: A. P(E) = 0.3. The probability of event E, denoted as P(E), is equal to 0.3.

To determine the correct answer, let's analyze the given information.

We know that events D and E are independent, which means that the occurrence of one event does not affect the probability of the other event happening.

Given:

P(D) = 0.6

P(D and E) = 0.18

Since events D and E are independent, the probability of both events occurring (P(D and E)) can be calculated as the product of their individual probabilities:

P(D and E) = P(D) * P(E)

Substituting the given values:

0.18 = 0.6 * P(E)

To find the value of P(E), we can rearrange the equation:

P(E) = 0.18 / 0.6

P(E) = 0.3

The asymptotes of the reciprocal function are x = 3 and y = 4. Also, the domain is x < 3 or x > 3 and the range is y < 4 or y > 4

The function is given as:

f(x) = -2[1/0.5(x -3)] + 4

A reciprocal function is generally represented as:

f(x) = a[1/(x -c)] + k

So, we have:

a = -2

c = -3 * 0.5

c = -1.5

k = 4

d = 0

Hence, the values of a, c, d and k are -2, -1.5, 0 and 4

We have:

f(x) = -2[1/0.5(x -3)] + 4

Set the radical to 0

y = 0 + 4

Evaluate

y = 4

Set the denominator to 0

x - 3 = 0

The grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.

To determine the number of trees the plum grower should plant per acre to maximize her harvest, we can set up an equation and use calculus to find the optimal solution. Let's denote the number of additional trees planted as x.

The yield of each tree can be represented by the equation:

Yield = 126 - 2x

The total yield per acre is then given by:

Total Yield = (26 + x) * (126 - 2x)

To maximize the harvest, we need to find the value of x that maximizes the total yield. We can achieve this by finding the maximum point of the quadratic equation representing the total yield.

Differentiating the equation with respect to x and setting it equal to zero, we can find the critical point:

d(Total Yield)/dx = -4x + 252 - 2(26 + x) = 0

Simplifying the equation, we get:

-4x + 252 - 52 - 2x = 0

-6x + 200 = 0

x = 200/6

x ≈ 33.33

Since we cannot have a fraction of a tree, the grower should plant 33 additional trees per acre to maximize her harvest. This gives a total of 26 + 33 = 59 trees per acre.

To find the maximum harvest, we substitute the value of x into the equation for the total yield:

Total Yield = (26 + 33) * (126 - 2 * 33)

Total Yield ≈ 59 * 60

Total Yield ≈ 3540 bushels

Therefore, the grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.
