The measure of the angles ∠1, ∠2, and ∠3 will be 38°, 65°, and 52°, respectively.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Angle ∠1 is given by the property of complementary. Then we have

∠1 + 38° = 90°

∠1 = 52°

Angle ∠1 and angle ∠3 are complementary angles. Then we have

∠1 + ∠3 = 90°

52° + ∠3 = 90°

∠3 = 52°

Angle ∠2 is given by the property of supplementary. Then we have

∠2 + 52° + 63° = 180°

∠2 = 65°

Answer: which triangle ;/

Step-by-step explanation:

the proportionality constant is 20 and in 8 ours it will cover 160 miles.

What is proportional relationship?

When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant.

The slope of he given graph will be (30-10)/(2-1) = 20

So here the proportionality constant is 20.

we can write y = 20x

This means in 8 ours it will cover 8*20 = 160 miles.

Hence, the proportionality constant is 20 and in 8 ours it will cover 160 miles.

Step-by-step explanation:

Q1. Since each of Bruce's tiles is one square foot in area, his equation is y=x, where y=area and x=#of tiles. The area increases by one square foot for every tile added.

Q2. If it takes 9 of Felicia's tiles to equal 1 square foot, her equation is y=(1/9)x. We can check the table to see if this equation is right. If you put 18 into this equation, you get 2, for 27 you get 3, and so forth

Q3. Bruce has the greater unit rate of 1 and has the tiles that cover the greatest area, as opposed to Felicia, whose unit rate is only 1/9, since each of her tiles covers 1/9 of a square foot

Q4. The slopes are the same as the unit rates. Bruce's is 1, Felicia's is 1/9. Both of their y intercepts are 0, because if they put down 0 tiles, there will be no area covered because the problem does not state that there were tiles placed already before Bruce and Felicia started. You can also see this by graphing their equations

Q5. Bruce's line is steeper, with a slope of 1, versus Felicia's slope, which is 1/9. This matches the comparison from part c where we discovered that Bruce had the greater unit rate

Answer:

w * (1 + 0.17) or w + (w * 0.17)

Step-by-step explanation:

Here are two expressions that represent the retail price of an item with an original cost of w dollars, assuming that the store marks up the price by 17%:

Retail price = w * (1 + 0.17)

This expression shows that the retail price is equal to the original cost multiplied by the markup percentage (0.17) plus 1. For example, if the original cost of the item is $100, the retail price would be $100 * (1 + 0.17) = $117.

Retail price = w + (w * 0.17)

This expression shows that the retail price is equal to the original cost plus the markup amount (which is equal to the original cost multiplied by the markup percentage). For example, if the original cost of the item is $100, the retail price would be $100 + ($100 * 0.17) = $117.

Representing data sets using frequency distributions and using graphs of frequency distributions can have several benefits. Here are some of the benefits of representing data sets using frequency distributions:

a) Organizing the data into afrequency  distribution can make patterns within the data more evident. By organizing the data into classes or bins and counting the number of observations within each class, you can see how the data is distributed and identify patterns or trends that may not be immediately apparent when looking at the raw data.

b) Organizing the data into a frequency distribution makes it possible to graph quantitative data. Many types of graphs, such as bar graphs and histograms, are based on frequency distributions and can be used to visualize the distribution of data.

c) It is easier to determine the minimum and maximum values of a data set when it has been arranged into a frequency distribution. By organizing the data into classes, you can easily see the range of values within each class and determine the overall range of the data set.

Here are some of the benefits of using graphs of frequency distributions:

a) It can be easier to determine the class boundaries by looking at a graph of the frequency distribution. When you create a graph of a frequency distribution, the class boundaries are often marked along the x-axis, which makes it easy to see where one class ends and the next begins.

b) Graphing a frequency distribution makes it possible to determine the relative frequencies of each of the classes. By looking at the heights of the bars on a bar graph or the heights of the columns on a histogram, you can see how each class compares to the others and determine the overall shape of the distribution.

c) It can be easier to identify patterns of a data set by looking at a graph of the frequency distribution. Graphs are a visual representation of data, and they can help you see patterns or trends that may not be immediately apparent when looking at the data in tabular form.

d) Graphing frequency distributions makes it possible to find the total number of observations. By adding up the frequencies of all the classes, you can determine the total number of observations in the data set.

Answer:

[tex]\dfrac{(y+2)^2}{4} -\dfrac{(x-4)^2}{9}=1[/tex]

Step-by-step explanation:

Given equation:

[tex]-4x^2 + 9y^2 + 32x + 36y - 64 = 0[/tex]

Collect like terms:

[tex]\implies 9y^2 + 36y -4x^2+ 32x - 64 = 0[/tex]

Move the constant to the right side of the equation:

[tex]\implies 9y^2 + 36y -4x^2+ 32x =64[/tex]

Factor out 9 from the terms in y, and 4 from the terms in x:

[tex]\implies 9(y^2 + 4y) -4(x^2-8x)=64[/tex]

Add the square of half the coefficient of the term in y and x inside the parentheses on the LHS, and the distributed values on the RHS:

[tex]\implies 9\left(y^2 + 4y+\left(\dfrac{4}{2}\right)^2 \right) -4\left(x^2-8x+\left(\dfrac{-8}{2}\right)^2 \right)=64+9\left(\dfrac{4}{2}\right)^2 \right+4\left(\dfrac{-8}{2}\right)^2 \right[/tex]

Simplify:

[tex]\implies 9(y^2 + 4y+4) -4(x^2-8x+16)=64+36-64[/tex]

[tex]\implies 9(y^2 + 4y+4) -4(x^2-8x+16)=36[/tex]

Factor the perfect trinomials:

[tex]\implies 9(y+2)^2 -4(x-4)^2=36[/tex]

Divide both sides by 36:

[tex]\implies \dfrac{9(y+2)^2}{36} -\dfrac{4(x-4)^2}{36}=\dfrac{36}{36}[/tex]

Simplify:

[tex]\implies \dfrac{\diagup\!\!\!\!9(y+2)^2}{\diagup\!\!\!\! 9\cdot 4} -\dfrac{\diagup\!\!\!\!4(x-4)^2}{9 \cdot \diagup\!\!\!\!4}=1[/tex]

An analyst makes a statistical error known as a sampling error when they choose a sample that does not accurately represent the complete population of data.

In statistics, a truly random sample involves selecting people from a population with an equivalent probability; in other words, picking individuals from a group without bias.

Failing to accomplish this appropriately will result in a sampling bias, which can dramatically increase the sample error in a systematic fashion. For instance, using a sample from just one nation to estimate the average height of all people on Earth could lead to a significant over- or underestimation.

In practice, it might be challenging to select an impartial sample because various criteria (for instance, nation, age, gender, and so on) may substantially bias the estimator. It is important to make sure that none of these aspects are taken into consideration when choosing the sample.
