The equation of the circle centered at the origin with a radius of 12 is x² + y² = 144.

In order to find the equation of a circle centered at the origin with a radius of 12, we need to use the standard form equation of a circle, which is:

(x - h)² + (y - k)² = r²

Where (h,k) represents the center of the circle, and r represents the radius.

In this case, since the circle is centered at the origin, h = 0 and k = 0. Also, since the radius is 12, we can substitute r = 12 in the above equation to get:

x² + y² = 12²

Simplifying further, we get:

x² + y² = 144

The value of function x is 4 - 2i.

Given information is that y = 1 + 2i and

x = y - (25ybar) / y²,

we can substitute the value of y in the equation of x as follows;

x = y - (25ybar) / y²

= (1 + 2i) - (25(1 - 2i)) / (1 + 2i)²

Now we have to find the value of x which can be found by simplifying the above equation as follows;

(1 + 2i)² = 1² + 2(2i) + (2i)²

= 1 + 4i - 4

= -3 + 4i`(1 + 2i)²

= -3 + 4i

Now, the value of x can be found as follows;

x = (1 + 2i) - (25(1 - 2i)) / (-3 + 4i)

= 1 + 2i - (25 - 50i) / (-3 + 4i)

= (1 + 2i) - ((25(-3 - 4i)) / (-3 + 4i)²)

= (1 + 2i) - ((-75 + 100i) / 25)

= (1 + 2i) - (-3 + 4i)

= 4 - 2i

Hence, the value of x is 4 - 2i.

A clementine sphere's volume is approximately  22.44 cubic inches.

According to the question, given that

The typical clementine has a diameter of 3.5 inches and is shaped like a sphere. . use 3.14 for \(\pi\)

The formula for a sphere's volume is

\(\frac{4}{3} \pi r^{3}\)

We know the diameter, but we can easily convert this into the radius by dividing it by 2, since the diameter is twice as long as the radius.

3.5/2 = 1.75

Now we can find the volume.

So, the average volume of a clementine is 22.46 cubic inches

Therefore, approximate volume of a clementine sphere is 22.44 cubic inches

The quantity of space occupied within a sphere is referred to as its volume. Every point on the surface of the sphere is equally spaced from its center, making it a three-dimensional round solid object. The fixed point and fixed distance are referred to as the sphere's center and radius, respectively. We will see the form alter when the circle is rotated. Thus, the rotation of the two-dimensional circular object yields the three-dimensional sphere shape.

For the distribution shown in the table, there were a total of 8 scores. Out of these 8 scores, two individuals had scores less than 23. This can be calculated by adding up the frequencies for the scores below x = 23, which in this case is 4 + 2 = 6. Therefore, 6 out of the 8 scores were less than x = 23.

In general, a distribution is a set of data points which are arranged according to certain criteria. They are used to represent the probability of an event occurring.

In this case, the distribution was used to show the frequency of scores for the given set of numbers. The frequency of each score is shown in the table. By looking at the table, we can easily calculate the total number of scores for the distribution, which is 8. We can also calculate how many individuals had scores less than x = 23, which is two.

Using the binomial distribution, it is found that there is a 0.037 = 3.7% probability that Adina's friend correctly identifies each of the 3 cups of water.

For each water, there are only two possible outcomes, either it is correctly identified, or it is not. The probability of a water being correctly identified is independent of any other water, hence the binomial distribution is used to solve this question.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability that each of the 3 cups is correctly identified is P(X = 3), hence:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 3) = C_{3,3}.(0.3333)^{3}.(0.6667)^{0} = 0.037\)

Answer:

the postulate that proves these two triangles congruent is AAA or angle angle angle.

Based on the given information and performing a one-sample t-test, the conclusion is that if the population mean (μ) is greater than 30.8294 km per litre, we reject the null hypothesis.

Given:

Sample mean (x') = 30 km per litre

Sample standard deviation (s) = 3.5 km per litre

Sample size (n) = 50

Significance level (α) = 0.05 (5%)

Null hypothesis \((H_0)\): The mean petrol consumption of the new car is equal to or higher than that of the existing car.

Alternative hypothesis \((H_1)\): The mean petrol consumption of the new car is lower than that of the existing car.

We'll calculate the test statistic (t-value) and compare it with the critical t-value.

The formula for the t-value is:

t = (x' - μ) / (s / √n)

where μ is the population mean (mean petrol consumption of the existing car).

First, we need to calculate the critical t-value from the t-distribution table. Since we have a significance level of 0.05 and (50 - 1) degrees of freedom, the critical t-value for a one-tailed test is approximately -1.677.

Now, let's calculate the t-value:

t = (30 - μ) / (3.5 / √50)

To reject the null hypothesis, the t-value should be less than the critical t-value.

Simplifying the equation:

t = (30 - μ) / (0.495)

To find the critical value, we compare it with the calculated t-value:

-1.677 > (30 - μ) / (0.495)

Multiplying both sides of the inequality by 0.495:

-0.8294 > 30 - μ

Rearranging the inequality:

μ > 30 + 0.8294

μ > 30.8294

Therefore, if the population mean (μ) is greater than 30.8294 km per litre, we reject the null hypothesis in favor of the alternative hypothesis, concluding that the mean petrol consumption of the new car is lower than that of the existing car.

The angle measures in this triangle are given as follows:

19. m<ABC = 44º.

20. m<CAG = 54º.

Since point G is the incenter of the triangle ABC, it means that segment BG is a bisection of the angle B, dividing it into two angles of equal measure, hence:

3x + 4 = 5x - 8

5x - 3x = 4 + 8

2x = 12

x = 6.

Then the measure of angle B is calculated as follows:

m<ABC = 2 x (3x + 4) = 2 x 22 = 44º.

The sum of the measures of the angles of a triangle is of 180º, and the measures are as follows:

Hence the measure of angle A in triangle ABC is calculated as follows:

x + 44 + 28 = 180

x = 180 - 72

x = 108º.

AG is a bisection of angle A, hence:

Using the conversion factors, we find that 3 cubic miles is approximately equal to 1.2504543 × 10^10 cubic meters. 5 cubic feet per second is equal to 2244.156 gallons per minute. 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.

1.1. One mile is equal to 1609.34 meters. Since we're dealing with cubic units, we cube the conversion factor.

1 mile = 1609.34 meters

1 mile³ = (1609.34 meters)³ = 4.168181 × 10^9 cubic meters

Therefore, 3 cubic miles is equal to 3 * 4.168181 × 10^9 cubic meters, which is approximately 1.2504543 × 10^10 cubic meters.

1.2. To convert from cubic feet per second (ft³/s) to gallons per minute (gal/min), we use the appropriate conversion factors.

Here are the conversion factors:

1 cubic foot = 7.48052 gallons

1 minute = 60 seconds

So, we set up the conversion as follows:

5 ft³/s * 7.48052 gal/ft³ * 60 s/min = 2244.156 gal/min

Therefore, 5 cubic feet per second is equal to 2244.156 gallons per minute.

1.3. To convert centimeters (cm) to nanometers per second squared (nm/sec²), we use the appropriate conversion factors. Here are the conversion factors:

1 centimeter = 10^7 nanometers

1 second = 1 second

So, we set up the conversion as follows:

9.50 cm * (10^7 nm/cm) / (1 sec)² = 9.50 * 10^7 nm/sec²

Therefore, 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.

The balance after 8 years in the savings account is Rs.16500 if the savings account earns 15% interest annually.

Simple Interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time.

Compound Interest can be defined as when the sum principal amount exceeds the due date for payment along with the rate of interest, for a period of time.

Formula. S.I. = (P × T × R) ⁄ 100.

Given that:

Initial deposit(P) = 7500

Rate of interest=15%

Time =8 years

By the use of simple interest,

We have Simple interest = (principal)(rate)(time)/100

Putting the value, we get

Simple interest=7500*15*8/100

By calculation we get

Simple interest = Rs.9000
