0.8342 as a fraction?

Answer:

-4.4

Step-by-step explanation:

In order to do this, we need to move the variables to one side, and the numerical values to the other.

-20-7x=-2x+2

We can do this by adding 7x to both sides first

-20=5x+2

Now we can subtract 2 from both sides.

-22=5x

Next, we can divide each side by 5.

x=-22/5

Then we simplify the fraction

x=-4.4

Answer:

x = -4.4

or

x = 22/-5

Step-by-step explanation:

-20-7x = -2x+2

-7x = -2x+20+2

2x-7x = 22

-5x = 22

x/-5 = 22/-5

x = -4.4

or

x = 22/-5

On solving the question 30.27 + 1.9 + 22.952 we get 55.1

Significant figures are important in calculations to maintain accuracy.

To add the numbers 30.27, 1.9, and 22.952:

Add the numbers: 30.27 + 1.9 + 22.952 = 55.122.

The number of significant figures in each of the given numbers is different. The answer should have the same number of decimal places as the number with the fewest decimal places, which in this case is 1.9. Thus, the answer should be rounded to 55.1

Based on the proportion of Chinese food menus Maura has already received (3 out of 15),we would expect her to receive approximately 4 Chinese food menus in the next batch of 20 menus.

To solve this, we look at the probability of Maura receiving a Chinese food menu by using the proportion of Chinese menus she has already received.

This initial probability is 3 out of 15, which simplifies to 1 out of 5. Therefore, we'd expect to receive the same proportion from the next set of menus.

To predict the number of Chinese food menus in the next 20, we multiply the total number of new menus by the probability of each being Chinese:

20 menus * (1/5 probability of Chinese) = 4 Chinese menus

Answer:

when they have equal sides and the exact shape and the same angle measures. they have tobe the same size.

Step-by-step explanation:

For example, when you have a square with sides 3 cm, then you compare it with the exact copy of the square. These squares are congruent. Two figures are congruent if and only if they have the exact same shape and the exact same size. If the corresponding sides of two figures with the same shape have the same length, then the two figures are congruent.

The figures that appear be congruent have all sides as equal and in the exact shape and can measure the same angles. They have the same size.

The instruments is those figures and objects that have the same size and shape. The meaning of the work congruent is that they are identical to each other and in an agreement and harmony

As per the example, the square with the sides of 3 cm, then you can compare it with the exact copy of the square. These squares are then congruent.

Answer:

∠a=80

∠b=50

Step-by-step explanation:

∠a and 100 are on a straight line. Therefore they are supplementary, and add to 180 degrees. So, we can say that:

∠a+100=180

To solve, subtract 100 from both sides. This will leave ∠a by itself.

∠a +100-100=180-100

∠a=80

The angles in a triangle must add to 180 degrees. Therefore,

∠a + ∠b + 50= 180

We know ∠a is 80, so we can substitute that in

80+ ∠b +50 =180

∠b+80+50=180

Combine like terms

∠b+(80+50)=180

∠b+130=180

To solve, subtract 130 from both sides. This will leave ∠b by itself.

∠b+130-130=180-130

∠b=50

Answer:

∠a = 80° and ∠b = 50°

Step-by-step explanation:

Look at angle a. Angle a and 100 both lie on the same line, which means they are supplementary and add up to 180. Then we can write: m∠a + 100 = 180. To solve this for a, we simply subtract 100 from both sides:

m∠a = 80°

Now, look at the triangle. All the angles in a triangle add up to 180, so we have the equation: m∠b + 80 + 50 = 180. Solve for b by subtracting 80 and 50 from both sides: m∠b = 50°.

Thus, ∠a = 80° and ∠b = 50°.

Step-by-step explanation:

Some of the population may not have access to other types of phones.

The policy of conducting a portion of surveys on mobile phones helps address the source of bias wherein some people may not have access to other types of phones. By including mobile phones, pollsters can have a more representative sample, reflecting the population more accurately. However, this does not guarantee participation or comprehension of survey questions.

The policy of political pollsters to conduct a percentage of their telephone interviews by calling mobile phones best addresses the source of bias that some of the population may not have access to other types of phones. This is reflective of a shift in communication behaviors wherein a significant percentage of the population exclusively uses mobile phones, especially among younger and middle-aged adults. This phenomenon could lead to a selection bias if only landline numbers were used, as the respondents would likely skew toward older individuals and those who are at home more often.

By integrating mobile phones in their survey methods, the pollsters are able to get a more representative sample that more accurately reflects the entire population. For instance, random-digit-dialing is a technique that allows pollsters to include respondents who have unlisted or mobile numbers. Similarly, geographically-based screenings can be employed to avoid regional bias.

However, it is important to note that including mobile phones in the survey does not address other kinds of bias. For instance, reaching out to potential respondents does not guarantee their participation, and it does not mean that the respondents would fully understand the wording of the survey questions. It only helps in achieving a more demographically reflective sample.

[tex]m=\frac{3}{2}[/tex]

Step-by-step explanation:

Step 1:  Find the slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-(-1)}{6-4}[/tex]

[tex]m=\frac{3}{2}[/tex]

Answer:  [tex]m=\frac{3}{2}[/tex]

we can write the equation of the line in slope-intercept form:

[tex]y =[/tex][tex](-1/12)x + 6[/tex]

To find the equation of a line in slope-intercept form ([tex]y = mx + b[/tex]), we need to determine the slope (m) and the y-intercept (b).

Given two points (0, 6) and (12, 5), we can calculate the slope (m) using the formula:

[tex]m = (y2 - y1) / (x2 - x1)[/tex]

Using the coordinates (0, 6) and (12, 5):

[tex]m = (5 - 6) / (12 - 0)[/tex]

[tex]= -1 / 12[/tex]

Now that we have the slope (m), we can substitute it into the slope-intercept form equation:

[tex]y = mx + b[/tex]

Using the coordinates (0, 6):

[tex]6 = (-1/12)(0) + b[/tex]

6 = b

Therefore, the y-intercept (b) is 6.

A slope-intercept equation is a linear equation written in the form y = mx + b, where m represents the slope of the line and b represents the y-intercept. The slope (m) determines the steepness or direction of the line, while the y-intercept (b) is the point where the line intersects the y-axis. By using this equation, we can easily identify the relationship between the x and y coordinateson  the line, making it convenient for graphing, understanding the line's behavior, and predicting the value of y for a given x.

Answer:

I can conclude that Sally went down the slide. I used deductive reasoning to get my answer. Sally said that if it was sunny, she would go to the park. She also said that if she does go to the park, she will go down the slide. Since Sally did go to the park, I know that she did go down the slide. Based on the information I have, I can use deductive reasoning to get to my answer.

Step-by-step explanation:

Based on Sally's conditions and the law of syllogism, since it's sunny, we can conclude Sally will go to the park and go down the slide.

From Sally's statements, since the next day is sunny, we can conclude that Sally will go to the park and go down the slide. This conclusion is based on the law of syllogism in logic, which allows us to link two related conditional statements. In this scenario, the first conditional statement is 'If it's sunny, I will go to the park', and the second is 'When I go to the park, I go down the slide'. As it's sunny, the law of syllogism lets us link these conditions to infer that Sally will indeed go down the slide at the park.

Answer:

Step-by-step explanation:

To use the formula for the volume of a prism to remember the formula for the volume of a cylinder, you can think of a cylinder as a prism with circular bases. The formula for the volume of a prism is given by multiplying the base area by the height. In the case of a cylinder, the base area is the area of a circle, which is πr² (where r is the radius), and the height is the height of the cylinder. Therefore, the formula for the volume of a cylinder becomes V = πr²h.

The formula for the volume of a cone is related to the formula for the volume of a cylinder because a cone can be thought of as a pyramid with a circular base. The formula for the volume of a cone is given by multiplying the base area (which is a circle) by the height and dividing by 3. Since the base area of a cone is πr² (where r is the radius), and the height of the cone is h, the formula for the volume of a cone becomes V = (1/3)πr²h. The volume of a cone is exactly one-third of the volume of a cylinder with the same base area and height.

It's important to note that the formulas for the volume of a cylinder, cone, and sphere are derived based on their geometric shapes and properties. Understanding these relationships and connections can help in remembering and applying the formulas correctly in problem-solving situations.
