What will the selling price be?

Answer:

2 : 3

Step-by-step explanation:

We have 4 squares and 6 circles. We would like the ratio of squares to circles, so we divide 4 by 6:

4 / 6  ⇒  the ratio here would be 4: 6

We need to simplify this. Notice that both 4 and 6 are divisible by 2. So, we can divide both by 2:

4/2: 6/2  ⇒  2 : 3

2 and 3 don't share any factors other than 1, so we leave the ratio like this.

The answer is thus 2 : 3.

The shape of the sampling distribution of p is approximately normal because n/N ≤ 0.05 and np(1 - p) < 10.

The mean of the sampling distribution of p is 0.763.

The shape of the sampling distribution of p is approximately normal if the sample size (n) is large enough compared to the population size (N) and if np(1 - p) is greater than or equal to 10.

We have n = 500 and N = 25,000, so we can check if np(1 - p) is greater than or equal to 10.

np(1 - p) = 500×0.763 × (1 - 0.763)

= 500 × 0.763 × 0.237

= 90.305.

Since np(1 - p) is greater than 10.

The shape of the sampling distribution of p is approximately normal because n/N ≤ 0.05 and np(1 - p) < 10.

2. The mean of the sampling distribution of p is equal to the population proportion, which is denoted by p.

The population proportion is given as p = 0.763.

Therefore, the mean of the sampling distribution of p is also 0.763.

On average, the sample proportions calculated from different samples of the same size will be centered around the population proportion.

The Possible Energy Collected in kJ is 30,999 kJ.

The first step in solving this problem is to determine the area of the oven. To do this, we need to multiply the length (53.2 cm) by the width (44.5 cm). This gives a result of 2359.4 cm².

Next, we can calculate the energy collected in kJ. To do this, we need to multiply the power (1120.3 W/m²) by the area of the oven (2359.4 cm²) and then by the time (71.9 min) and then divide by 1000 to convert into kilojoules (kJ). This gives the following equation:

Energy collected (kJ) = (1120.3 W/m² × 2359.4 cm² × 71.9 min) / 1000

Substituting in the values, this gives a result of 30,999 kJ of energy collected.

Therefore, the Possible Energy Collected in kJ is 30,999 kJ.

In this problem, a researcher wants to estimate the number of households with two cars with 95% confidence and a margin of error of 5%. The researcher also knows that a previous study showed that 22% of households had two cars. The possible answers are 4, 339, and 186.

To answer this question, we need to use the formula for sample size calculation: n = (Z^2 * p * q) / E^2, where n is the sample size, Z is the Z-score for the desired level of confidence (in this case, 1.96 for 95% confidence), p is the estimated proportion of the population with the characteristic of interest (in this case, 0.22), q is the complement of p (q = 1 - p), and E is the desired margin of error (in this case, 0.05). Plugging in these values gives us n = (1.96^2 * 0.22 * 0.78) / 0.05^2, which simplifies to n = 186.

Therefore, the correct answer is (c) 186. This means that the researcher needs to survey 186 households to estimate the number of households with two cars with 95% confidence and a margin of error of 5%.

The value of 0 in the interval [0°, 360°) such that sin 0 ≈ 0.4535971 is approximately 25.8256° and 334.1744°.

To find the values of 0 that satisfy sin 0 ≈ 0.4535971, we can use inverse trigonometric functions. The inverse sine function, denoted as sin^(-1) or arcsin, gives us the angle whose sine is a given value. In this case, we want to find the angle whose sine is approximately 0.4535971.

Using a calculator or a table of trigonometric values, we can find the inverse sine of 0.4535971, which is approximately 25.8256°. However, sine is a periodic function with a period of 360°, so there will be infinitely many angles that satisfy sin 0 ≈ 0.4535971.

To find additional solutions, we can add or subtract multiples of 360°. Therefore, another solution can be obtained by adding 360° to the previous angle, resulting in approximately 334.1744°.

In conclusion, the values of 0 in the interval [0°, 360°) that satisfy sin 0 ≈ 0.4535971 are approximately 25.8256° and 334.1744°.

square root of 729= 9

9×9=81

Answer:

Step-by-step explanation:

Formula of Volume= \(a^{3}\) - a = side

Therefore since the volume is given you just need to find the side.

729=\(a^{3}\) = \(\sqrt[3]{729}\) = a

            = 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Each dividend is 20 times the divisor.

Each dividend is 10 times the dividend below it.

Each divisor is 10 times the divisor below it.

The quotient of each pair of numbers is therefore the same.

The rate of change of a linear function is determined by the slope of the function and here for y = mx + b the slope is m as the funtion is in Slope intercept form.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Slope indicates that for every unit change in the independent variable, x, the dependent variable will vary by the same amount, b. Slope indicates both direction and steepness. Positive slope causes the line to rise when it goes from left to right. When the slope is negative, the line descends when moving from left to right.

Here,

You may get the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two places. Rise divided by Run gives you the slope. Run = rise + slope Rise + run = slope.

Converting the given decimal numbers to hexadecimal and then to binary, we find that

(a) 757.1710 is equivalent to 2F5.2E16 in hexadecimal and 1011110101.001011002 in binary.

(b) 356.2510 is equivalent to 164.4016 in hexadecimal and 101100100.01000011012 in binary.

To convert a decimal number to hexadecimal, we divide the whole number part and the fractional part separately by 16 and convert the remainders to hexadecimal digits.

For the whole number part of (a) 757, dividing it by 16 gives us a quotient of 47 and a remainder of 5, which corresponds to the hexadecimal digit 5.

Dividing the fractional part 0.17 by 16 gives us a hexadecimal digit of 2. Combining these digits, we get the hexadecimal representation 2F5.

To convert (b) 356 to hexadecimal, we divide it by 16, obtaining a quotient of 22 and a remainder of 4, which corresponds to the hexadecimal digit 4.

For the fractional part 0.25, dividing by 16 gives us a hexadecimal digit of 1. Combining these digits, we get the hexadecimal representation 164.

To convert hexadecimal numbers to binary, we simply replace each hexadecimal digit with its equivalent four-digit binary representation. Converting (a) 2F5 to binary, we get 1011110101.

Similarly, converting (b) 164 to binary, we get 101100100.

For the fractional parts, converting 0.2E to binary gives us 0010, and converting 0.401 to binary gives us 01000011.

Therefore, (a) 757.1710 is equivalent to 2F5.2E16 in hexadecimal and 1011110101.001011002 in binary, while (b) 356.2510 is equivalent to 164.4016 in hexadecimal and 101100100.01000011012 in binary.

Dilation x180 degrees around the origin, and then a translation across the y axis

Step-by-step explanation:

From what I can tell, you are looking for the series of transformations that happen to the triangle, so that's the answer I provided. Ignore if not.

The statement that knowing the value of x tells you nothing about the value of y can be explained by several scenarios. One possible scenario is when the values of x and y are not related in any way. In other words, there is no mathematical or logical connection between them.

Another scenario where knowing the value of x tells you nothing about the value of y is when there are multiple possible values of y for a given value of x. This occurs when the relationship between x and y is not one-to-one. For instance, if x represents a person's age and y represents their height, knowing someone's age does not determine their height since there are different heights for different ages.

Furthermore, it is possible that there is a relationship between x and y, but the value of y is affected by other factors besides x. For example, if x represents the amount of time a student spends studying and y represents their grade on a test, knowing the value of x does not completely predict the value of y because other factors like natural ability and test-taking skills may also play a role in determining the grade.
