Answer: 15h

Step-by-step explanation:

The radius of the circle is 9 units. The center of the circle is at (5, 0).

The given equation is (x – 5)²y² = 81.

To identify the radius and center of this circle, we can rewrite the equation in standard form.

First, let's divide both sides by 81 to get (x – 5)²y²/81 = 1.

Next, we can take the square root of both sides to eliminate the squared terms.

This gives us the equation (x – 5)/9 · y/3 = 1.

The standard form of a circle is (x – h)² + (y – k)² = r², where (h, k) is the center of the circle and r is the radius.

Comparing this form to our equation, we can see that (x – 5)/9 and y/3 correspond to (x – h) and (y – k), respectively.

Therefore, we can solve for h and k by setting (x – 5)/9 = 0 and y/3 = 0, respectively.

This gives us h = 5 and k = 0, so the center of the circle is (5, 0). Finally, we can solve for the radius r by noting that the

distance from the center (5, 0) to the edge of the circle is 3 units in the x-direction and 9 units in the y-direction.

Therefore, the radius of the circle is 9 units, and we can express our final answer as:

The radius of the circle is 9 units. The center of the circle is at (5, 0).

The length of the original piece of fabric, given the proportion cut by Yu Yan and the amount cut in total, is 75 .75 inches

Assume that the original length of fabric was denoted as x, this means that the first cutting by Yu Yan took out :

= 1 / 3 x

The equation would then be :

x - 1 / 3 x - 10 - 5 = 35 + 1 / 2

x - 1 / 3 x - 10 - 5 = 35 . 5

The length of the original fabric is:

2 / 3x  = 35. 5 + 10 + 5

x = 50. 5 ÷ 2 / 3

x = 50. 5 x 3 / 2

A typical water bed weighs around 1797.6 pounds. It depends upon the volume of water bed and the unit conversion of the weight and volume units.

A typical water bed holds 28 cubic feet of water.

The volume of the typical water bed and its weight can be calculated with the help of the quantities:

Identify the volume of water held by the water bed, which is 28 cubic feet.
Multiply the volume by the weight of 1 cubic foot of water, which is 64.2 pounds.
Perform the calculation: 28 cubic feet × 64.2 pounds per cubic foot = 1797.6 pounds.

Answer: y=8 m=5

Step-by-step explanation:

Answer:

1. 3.125

2. 4.5

Step-by-step explanation:

1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.

2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.

ln(6x) - ln(6y) = ln(6x/6y)

To simplify the expression ln(6x) - ln(6y) using the properties of logarithms, we can combine the two logarithms into a single logarithm by applying the quotient rule of logarithms.

The quotient rule states that ln(a) - ln(b) is equal to ln(a/b). In this case, we have ln(6x) - ln(6y). By applying the quotient rule, we can rewrite it as ln((6x)/(6y)).

Simplifying further, we can cancel out the common factor of 6 in the numerator and denominator, resulting in ln(x/y). Therefore, the expression ln(6x) - ln(6y) can be written as ln(x/y), where x and y are positive numbers.

By combining the two logarithms using the quotient rule, we obtain a single logarithm that represents the ratio of x to y. This simplification can be useful for further calculations or analysis involving logarithmic functions.

Answer:

T_n = 160(0.05)^(n - 1)

At T_n = 100, n = 1 year

Step-by-step explanation:

We will use geometric progression to solve this question.

Formula for nth term of a GP is;

T_n = ar^(n - 1)

We are told the population of its high school decreases by 5% each year.

This means r = 0.05

senior class has 160 students. Thus a = 160

Thus,T_n = 160(0.05)^(n - 1)

Where n is number of years after now.

We want to find the number of years before the class will have 100 students

Thus;

160(0.05)^(n - 1) = 100

(0.05)^(n - 1) = 100/160

(n-1)In 0.05 = In (100/160)

-2.9957(n - 1) = -0.47

(n - 1) = 0.47/2.9957

n = 1 + 0.1569

n = 1.1569

Approximating to the nearest whole number gives n = 1

False , the variance and standard deviation are not measures of central location

Given data ,

The variance and standard deviation are not measures of central location but measures of dispersion or spread of a dataset

Measures of central location include the mean, median, and mode, which represent the typical or central value of a dataset

The variance and standard deviation are measures of dispersion or spread in a dataset. They provide information about how the values in a dataset are spread out around the mean.

In order to understand the variability or dispersion of data points within a dataset, one must take into account both the variance and standard deviation. They provide information on the range of values and aid in calculating how far away from the mean certain data points are. In statistics and data analysis, these metrics are frequently used to comprehend and evaluate the variance of various datasets.

The probability that the mean weight of 36 different women is between 140LB and 211LB is approximately 0.9874.

There can only be one value for a random variable. A random variable's value could be zero with a probability of zero. A probability distribution's total probabilities are always equal to one.

a. We must convert the weight to a typical normal distribution using the following formula in order to determine the likelihood that a randomly chosen woman weighs between 140LB and 211LB.

z = (x - μ) / σ

If the weight x, the mean weight, and the standard deviation are all given. The probability can then be determined using a calculator or a typical normal table.

When x=140LB, we get:

z = (140 - 165) / 45.6 = -0.5461

x = 211LB results in:

z = (211 - 165) / 45.6 = 1.0096

The area under the standard normal curve between z = -0.5461 and z = 1.0096 is found to be roughly 0.6267 using a typical normal table or calculator.

Hence, the likelihood that a lady chosen at random weighs between 140LB and 211LB is roughly 0.6267.

b. We must normalise the sample mean to a standard normal distribution using the following method in order to determine the likelihood that the mean weight of 36 individual women is between 140LB and 211LB.

z is equal to (x - ) / (n / sqrt(n)).

When n is the sample size, x is the sample mean weight, is the mean weight, and is the standard deviation. The probability can then be determined using a calculator or a typical normal table.

To solve this issue, we have:

μ = 165LB

σ = 45.6LB

n = 36

If x = 140 LB, we get:

z = (140 - 165) / (45.6 / sqrt(36)) = -2.4994

With x = 211LB, we get:

z = (211 - 165) / (45.6 / sqrt(36)) = 2.4994

The area under the standard normal curve between z = -2.4994 and z = 2.4994 is found to be around 0.9874 using a standard normal table or calculator.

Hence, there is a roughly 0.9874 percent chance that the average weight of 36 individual women falls between 140LB and 211LB.
