What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

1) From first figure,

⇒ ∠ 3 = 54°   (Two sides are equal hence two angles are also equal)

Hence, We get;

∠3 + ∠4 + 54° = 180°

54° + ∠4 + 54° = 180

∠4 = 180 - 108

∠4 = 72°

Hence, We get;

∠ 1 = ∠ 4

∠ 1 = 72°

And, ∠2 = ∠3 = 54°

2) From second figure,

∠ 4 = 90 - 59°

      = 31°

And, We have;

∠1 = 59°

And, Diagonal bisect each other.

Hence,

∠ 2 = ∠ 3 = 90°

3) From third figure,

∠ 2 = 68°

Hence, 2 ∠ 1 = 180 - 136°

2 ∠ 1 = 44°

∠ 1 = 22°

And, We have;

Since, ∠ 2 = 68°

Hence, ∠ 3 = 68°

And. ∠ 4 = 90° (right angle)

Find the measure of the central angle of the sector that represents 64% of a circle graph. Round to the nearest degree if necessary. Show your work!!!!

Answers

Answer:

To find the central angle of the sector that represents 64% of a circle graph, we can use the proportion:

64% (or 0.64) of the circle is to 360 degrees as x (the central angle of the sector) is to the angle we're trying to find.

Mathematically, we can write:

0.64/1 = x/360

Simplifying this expression, we get:

x = 0.64 x 360/1

x = 230.4

So the central angle of the sector that represents 64% of the circle graph is approximately 230.4 degrees. Rounded to the nearest degree, this is 230 degrees.

Find the numbers of bags of potting soil that a company can produce for seedlings, general potting, and hardwood plants with the given amounts of raw materials. The raw materials used in one bag of each type of potting soil are shown below.
Sand Loam Peat Moss
Seedlings 2 units 1 unit 1 unit
General 1 unit 2 units 1 unit
Hardwoods 2 units 2 units 2 units
450 units of sand
450 units of loam
360 units of peat moss

Answers

Company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants. The solution has been obtained by using linear equation.

What is a linear equation?

The degree of the linear equation is 1. It is very clear that linear equations with exponents greater than one lack variables. The equation for this graph yields a straight line.

Let S be the bags of seedlings, G be for general potting, and H be for hardwood plants.

It is given that each bag of seedling soil needs 2 units of sand, each bag of general soil needs 1 unit of sand, and each bag of hardwood soil needs 2 units of sand. We have 450 units of sand.

So, from this we get

2S + G + 2H = 450      ...(1)

Similarly, for units of loam and peat moss, we get the equations as

S + 2G + 2H = 450      ...(2)

S + G + 2H = 360         ...(3)

Now, on subtracting (3) from (2), we get

G = 110

On substituting this, we get

2S + 2H = 360    ...(4)

S + 2H = 230    ...(5)

S + 2H = 250    ...(6)

Now, we subtract (2) from (1), we get

S = 130

On substituting this in equation (5), we get

130 + 2H = 230

2H = 100

H = 50

Hence, company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants.

Evan volunteers on the weekend at the Central Library. As a school project, he decides to record how many people visit the library, and where they go. On Saturday, 433 people went to The Youth Wing, 335 people went to Social Issues, and 367 went to Fiction and Literature.
On Sunday, the library had 600 total visitors. Based on what Evan had recorded on Saturday, about how many people should be expected to go to Fiction and Literature? Round your answer to the nearest whole number.

Answers

Answer: Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.

Step-by-step explanation:

To estimate how many people to expect in the Fiction and Literature section on Sunday, we can assume that the proportion of visitors to each section remains the same as it was on Saturday.

First, we need to calculate the total number of visitors on Saturday:

433 (Youth Wing) + 335 (Social Issues) + 367 (Fiction and Literature) = 1135

Next, we can find the proportion of visitors to the Fiction and Literature section:

367 (Fiction and Literature) / 1135 (total visitors on Saturday) ≈ 0.323

We can use this proportion to estimate the number of visitors to the Fiction and Literature section on Sunday:

0.323 (proportion of visitors to Fiction and Literature) x 600 (total visitors on Sunday) ≈ 194

Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.

Since the two tests are independent, we can use the multiplication rule for independent events to find the probability that both tests fail to detect the disease in someone who has it:

P(both tests fail) = P(test i fails) × P(test ii fails)

P(test i fails) = 0.30 (as given in the problem)

P(test ii fails) = 0.25 (as given in the problem)

Substituting the values, we get:

P(both tests fail) = 0.30 × 0.25

P(both tests fail) = 0.075

what is the numpy randomize columns in array?

Answers

In NumPy, you can randomize the order of the columns in a 2-dimensional array using the numpy.random.permutation() function.

Here's an example of how to use this function to randomize the order of the columns in a 2-dimensional array:

import numpy as np

# create a 2-dimensional array with 3 rows and 4 columns

arr = np.array([[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]])

# get the number of columns in the array

num_cols = arr.shape[1]

# create a list of column indices

col_indices = np.arange(num_cols)

# shuffle the column indices randomly

shuffled_col_indices = np.random.permutation(col_indices)

# use the shuffled column indices to reorder the columns in the array

arr_shuffled = arr[:, shuffled_col_indices]

# print the original array and the shuffled array

print("Original array:")

print(arr)

print("Shuffled array:")

print(arr_shuffled)

In this example, we first create a 2-dimensional array with 3 rows and 4 columns. We then use the np.arange() function to create a list of column indices, which we shuffle randomly using the np.random.permutation() function.

Finally, we use the shuffled column indices to reorder the columns in the original array and store the result in a new array called arr_shuffled.

The output of the code will be the original array followed by the shuffled array, with the columns randomly rearranged.

Given h (x) = (1/b(x - h))³ + k and the points (-5,-5), (1,-2), (-2,-3), find "b" and write the equation in standard form.

Answers

Answer and Step-by-step explanation:

To find "b" and write the equation in standard form, we need to use the given points and the general form of the function:

h(x) = (1/b(x - h))³ + k

First, we can use the point (-5, -5):

-5 = (1/b((-5) - h))³ + k

Next, we can use the point (1, -2):

-2 = (1/b((1) - h))³ + k

Finally, we can use the point (-2, -3):

-3 = (1/b((-2) - h))³ + k

We can use these three equations to solve for "b" and "h". One way to do this is to subtract the third equation from the first equation, which gives:

2 = (1/b(3 - h))³

Taking the cube root of both sides and multiplying by b gives:

b³ = 1/8

b = 1/2

Now that we have found "b", we can use the second equation to solve for "h":

-2 = (1/2(1 - h))³ + k

Simplifying this equation and using the fact that k is a constant, we get:

-8 = (1 - h)³ + 8k

-1 = (1 - h)³ + k

We can use this equation along with the point (-5, -5) to solve for "h":

-5 = (1/2((-5) - h))³ + k

-5 = (1/2(-5 - h))³ + k

-5 = (1/2(-5 - h))³ + (-1/8)

-40 = (-5 - h)³

Taking the cube root of both sides and multiplying by -1 gives:

h = 5 - ∛(-40)

h = 5 + 2∛10

Now we have found "b" and "h", and we can use them to write the equation in standard form. First, we substitute the value of "b" into the general form of the function:

h(x) = (1/(1/2(x - (5 + 2∛10))))³ + k

Simplifying this expression and using the fact that k is a constant, we get:

h(x) = 8(x - (5 + 2∛10))³ + k

This is the equation in standard form. We could expand and simplify the expression further, but this is the final answer.

To find sin(a),

[tex] \sin( \alpha ) = \sqrt{1 - \cos {}^{2} ( \alpha ) } [/tex]

[tex] \sin( \alpha ) = \sqrt{1 - (0.6) {}^{2} } [/tex]

[tex] \sin( \alpha ) = \sqrt{0.64} [/tex]

Since sin is negative in the interval (270,360)

[tex] \sin( \alpha ) = - 0.8[/tex]

Now we can find sin(2a)

[tex]2( - 0.8)(0.6) = - 0.96[/tex]

2. The identity for cos(2x) is

[tex]2 \cos {}^{2} (x) - 1[/tex]

We know cos x is 0.6 so we get

A oil company has purchased an option on land in Alaska.

To determine the likelihood of finding oil, the company conducted preliminary geologic studies to assign prior probabilities of finding high-quality oil (0.65), medium-quality oil (0.20), or no oil (0.15). Therefore, the probability of finding oil is 0.65 + 0.20 = 0.85.

After 200 feet of drilling on the first well, a soil test was taken to determine the likelihood of finding high-quality oil (0.20), medium-quality oil (0.80), or no oil (0.20).

The results of this test should be interpreted as follows: the probability of finding oil has decreased since the prior probabilities.

Therefore, the revised probabilities are 0.20 + 0.80 = 1.00. This means that the oil company has a 100% probability of finding either high-quality or medium-quality oil.

The two shorter sides are 52 cm in length

The two longer sides are 1.5 times the length of the shorter sides

= 52 x 1.5 = 78 cm

The two longer sides are 78 cm in length

Now, just add all the sides

52 + 52 + 78 + 78 = 260

The perimeter is 260 cm.

What is the conversion of 28 inch to cm ?

Answers

The conversion of 28 inch to cm is 71.12 cm.

Kilometer (km) and mile are both units of distance or length, but they are used in different parts of the world.

A kilometer is a metric unit of length used in most countries outside the United States. It is defined as 1,000 meters, or approximately 0.62 miles.

To convert inches to centimeters, you can use the conversion factor of 1 inch = 2.54 centimeters.

So, to convert 28 inches to centimeters, you can multiply 28 by 2.54:

28 inches * 2.54 cm/inch = 71.12 cm

Therefore, 28 inches is approximately equal to 71.12 centimeters.

when computing the correlation​ coefficient, what is the effect of changing the order of the variables on​ r?

Answers

The correlation coefficient, denoted by "r," measures the strength and direction of the linear relationship between two variables. Changing the order of the variables does not affect the value of r.

That is, if we calculate the correlation coefficient between variable X and variable Y, and then switch the order to calculate the correlation coefficient between variable Y and variable X, we will obtain the same result.

This is because the correlation coefficient measures the degree to which two variables are related, regardless of which variable is considered the predictor or the outcome.

In other words, the relationship between X and Y is the same as the relationship between Y and X. The correlation coefficient only changes if the actual relationship between the two variables changes.

Therefore, the order in which we consider the variables does not affect the correlation coefficient, as long as we are measuring the correlation between the same two variables.
