Step-by-step explanation:

The area of each triangle = 1/2 * height * base

As it is a right triangle the height is equal to one of its sides, so

Area of 1 triangle = 1/2 * 6 * 5

= 15 cm^2

Area of mosaic = 150 * 15

= 2250cm^2.

On solving the provided question, we can say that in the triangle LM = 2*(IJ) x = |-6| = 6 and LM = 4x + 8 = 32 units

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

given,

LM = 4x + 8 and IJ = 5x +22

in the triangle LM = 2*(IJ)

4x + 8 = 2*(5x + 22)

4x + 8 = 10x + 44

6x + 36

x = |-6| = 6

LM = 4x + 8 = 32 units

Answer:

Step-by-step explanation:

For the given research scenario, the recommended sampling technique is Stratified Sampling.

Stratified Sampling involves dividing the population into homogeneous subgroups called strata and then selecting samples from each stratum based on its proportion in the population. In this case, since the proportion is known to be 50%, stratifying the sample will ensure representation from both sides of the proportion, increasing the accuracy of the results.

Random Sampling Techniques: 1. Simple Random Sampling: This technique randomly selects individuals from the population without any stratification or clustering. However, it may not guarantee an equal representation of the proportion and may result in a less accurate estimation of the population parameter. 2. Cluster Sampling: Cluster Sampling involves dividing the population into clusters and randomly selecting a few clusters for the study. This technique might not be suitable in this scenario since the clusters may not necessarily reflect the desired proportion accurately. 3. Systematic Sampling: Systematic Sampling involves selecting every nth element from the population list. While it can be efficient, it may introduce biases if there is a systematic pattern in the population list.

Non-random Sampling Techniques: 1. Purposive Sampling: This technique involves handpicking individuals based on specific criteria. It may introduce researcher bias and may not provide a representative sample. 2. Convenience Sampling: Convenience Sampling involves selecting individuals who are readily available and accessible. It may result in a biased sample as it does not consider the proportional representation of the population.3. Quota Sampling: Quota Sampling involves selecting individuals to meet specific quotas set by the researcher. Similar to convenience sampling, it may result in biased samples and does not guarantee proportional representation.4. Snowball Sampling: Snowball Sampling involves selecting initial participants and then using their referrals to recruit additional participants. While it can be useful for hard-to-reach populations, it may introduce selection biases and may not represent the desired proportion accurately.

The exponential function passing through the points (-3, 1/2) and (3, 32) can be represented by the equation \(f(x) = (2^{(5/6)}) * (2^{(x/6)})\).

To find the exponential function passing through the given points, we can start by assuming the general form of an exponential function, \(f(x) = a * (b^x)\), where a and b are constants to be determined. Plugging in the coordinates (-3, 1/2) into this equation gives us \(1/2 = a * (b^{(-3)})\), and plugging in (3, 32) gives us \(32 = a * (b^3)\).

Now, we can solve this system of equations to find the values of a and b. Taking the ratio of the two equations, we get \((1/2) / 32 = (a * (b^{(-3)})) / (a * (b^3))\), which simplifies to \(1/64 = 1/b^6\). Solving for b, we find \(b = 2^{(1/6)\).

Substituting this value back into either of the original equations, we can solve for a. Using the equation \(1/2 = a * (2^{(-3/6)})\), we find \(a = 2^{(5/6)\).

Therefore, the exponential function passing through the given points is \(f(x) = (2^{(5/6)}) * (2^{(x/6)})\).

Step-by-step explanation:

The difference is 1/3. Twelve by three is four. Nine by three is three. The different from 9 to 12 is 1/3.

Answer: -5/2 or 1/6

Step-by-step explanation:

I6n + 7I = 8

Therefore (6n + 7) = 8 or -8 because modulus means we're only getting it's absolute value, (it's positive value) meaning it could equal 8 or -8 before it's modulus'ed.

Therefore 6n + 7 = 8

or 6n + 7 = -8

Leaving us with:

6n = 1

6n = -15

So n = 1/6

or n = -5/2 (-2.5)

Answer:

n = 1/6                          n = -5/2

Step-by-step explanation:

|6n+7|=8

This has two solutions, one positive and one negative

6n+7 = 8  and 6n+7 = -8

Subtract 7 from each side

6n+7-7 = 8-7         6n+7-7 =-8-7

6n =1                        6n = -15

Divide by 6

6n/6 = 1/6                 6n/6 = -15/6

n = 1/6                          n = -5/2

A right circular cone has a lateral area of 569 square millimeters, and its slant height is twice its radius. The radius of the right circular cone is approximately 10 millimeters.

Let's assume that the radius of the cone is denoted by 'r' millimeters. According to the problem, the slant height is twice the radius, so it can be expressed as 2r millimeters.

The lateral area of a right circular cone is given by the formula A = πrl, where 'r' is the radius and 'l' is the slant height. We are given that the lateral area of the cone is approximately 569 square millimeters.

Substituting the known values into the formula, we have:

569 = π(r)(2r)

To solve for 'r', we can rearrange the equation:

2πr² = 569

Dividing both sides by 2π, we get:

r² = 569 / (2π)

Using a calculator to evaluate the right-hand side, we find:

r² ≈ 90.7

Taking the square root of both sides, we obtain:

r ≈ √(90.7)

Approximating the square root to the nearest whole millimeter, we find that the radius 'r' is approximately 10 millimeters.

Therefore, the radius of the right circular cone is approximately 10 millimeters.

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

The way to show this expression is 6(4+5) because "and" is showing the distributive property.

(A) The percentage is approximately 62.07%.

(B) percentage of years will have an annual rainfall of more than 39 inches is 72.17%.

(C) the smaller percentage from the larger one: 50.48% - 22.17% = 28.31%.

First, let's recall that the normal distribution is characterized by the mean and standard deviation. In this case, the mean annual rainfall is 42.3 inches and the standard deviation is 5.6 inches.

To answer your questions, we'll use the Z-score formula: Z = (X - mean) / standard deviation. Then, we can use a Z-table or calculator to find the percentage.

a) For annual rainfall less than 44 inches:
Z = (44 - 42.3) / 5.6 = 1.7 / 5.6 ≈ 0.3036
Using a Z-table or calculator, the percentage is approximately 62.07%.

b) For annual rainfall more than 39 inches:
Z = (39 - 42.3) / 5.6 = -3.3 / 5.6 ≈ -0.5893
Using a Z-table or calculator, the percentage for LESS than 39 inches is approximately 27.83%. To find the percentage of years with more than 39 inches, subtract from 100%: 100% - 27.83% = 72.17%.

c) For annual rainfall between 38 and 43 inches:
Z1 = (38 - 42.3) / 5.6 ≈ -0.7679
Z2 = (43 - 42.3) / 5.6 ≈ 0.1250
Using a Z-table or calculator, the percentage for Z1 is 22.17%, and for Z2 is 50.48%. To find the percentage between these two Z-scores, subtract the smaller percentage from the larger one: 50.48% - 22.17% = 28.31%.

So, the answers are: a) 62.07%, b) 72.17%, and c) 28.31%.

the probability of drawing a red, then a blue, and then a white marble is \(=\frac{7}{225}\)

To find probability, we take the number of ways the specific event can occur and divide it by the number of ways any event can occur.

The probability of drawing a red marble is: (of red marbles) / (total # of marbles) = 3/(3 + 7 + 5) = 3÷15 = 1÷5.

The probability of drawing a blue marble is: ( of blue marbles) / (total # of marbles) = 5/(3 + 7 + 5) = 5÷15 = 1÷3.

The probability of drawing a white marble is: ( of white marbles) / (total # of marbles) = 7/(3 + 7 + 5) = 7÷15.

Now, we want these events to all to occur for us. So, we must multiply them by each other: (1/5) * (1/3) * (7/15)  \(=\frac{7}{225}\)

Thus, the probability is \(=\frac{7}{225}\)
