Complete the statements to find the measurements of ∠a and ∠b .
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°.
-20-7x=-2x+2 solve the equation
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

Political pollsters now make sure to conduct a percentage of their telephone interviews by calling mobile phones. This policy best addresses which potential source of bias? Some of the population may not have access to other types of phones. The survey only reaches individuals who volunteer to be interviewed. The policy helps individuals understanding the wording of survey questions. Some individuals contacted may choose to not participate.
Answer:
The answer is A
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.
Explanation: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.

Restaurants often slip takeout menus under Maura's apartment door. So far, Maura has collected 15 menus, including 3 for Chinese food. Considering this data, how many of the next 20 menus slipped under Maura's door should you expect to be from Chinese restaurants? menus
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

The points (0, 6) and (12, 5) fall on a particular line. What is its equation in slope-intercept
form?
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.

The marginal distribution of train arrival status shows that approximately 90% of the time the train is on-time and 10% of the time it is delayed. This is calculated by taking the frequency of each arrival status and expressing it as a percentage of the total number of days recorded by James.
James has been keeping track of the relationship between weather conditions and whether the downtown train runs on time.
To find the marginal distribution of train arrival status in percentages, we need to see the frequency of on-time and delayed trains irrespective of the weather conditions and then express these frequencies as a percentage of the total number of days recorded.
To calculate the on-time percentage:
Total on-time occurrences: 330Total recordings: 365On-time percentage = (Total on-time occurrences / Total recordings) x 100On-time percentage = (330 / 365) x 100 ≈ 90%To calculate the delayed percentage:
Total delayed occurrences: 35Delayed percentage = (Total delayed occurrences / Total recordings) x 100Delayed percentage = (35 / 365) x 100 ≈ 10%Therefore, the marginal distribution of arrival status is approximately 90% on-time and 10% delayed.

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.
To remember the formula for the volume of a cylinder, think of it as a prism with circular bases. The formula is the area of the base times the height. The volume of a cone with the same radius and height is one-third of the volume of the cylinder.
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 the area of the base times the height. Since the bases of a cylinder are circles, the formula becomes the area of the base (πr²) times the height (h). The formula for the volume of a cylinder is related to the formula for the volume of a cone because if you take a cone with the same radius and height as a cylinder, the volume of the cone will be one-third of the volume of the cylinder (Vcone = 1/3 * Vcylinder).
