Answer:
y = -3/4x - 1/4.
Step-by-step explanation:
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
Given the slope : -3/4 and y-intercept : -1/4, the equation of the line is y = -3/4x - 1/4.

a stem-and-leaf diagram is constructed by separating each value of a data set into two parts. what are these parts?
A stem-and-leaf diagram separates each value of a data set into two parts: the stem and the leaf.
The stem is the first part of the number, typically the largest place value, and it is used to group similar values together. The leaves are the last part of the number, typically the smallest place value, and they provide the specific values within each group.
For example, consider a data set with the values 15, 19, 10, 11, 15. In a stem-and-leaf diagram, the stem for these values would be 1 and the leaves would be 5, 9, 0, 1, and 5, respectively.
The stem-and-leaf diagram would then look something like this:
1 | 0 1 5 5 9This format allows for a quick visualization of the distribution of the data and can be useful for identifying patterns and relationships within the data set.

after their soccer game, isabella and her friends eat at their favorite restaurant, the dancing meatball. when the bill comes, they divide the cost of a meatball pizza evenly among 5 people. each person pays $3.25.which equation can you use to find the cost c of the pizza?
The equation that can be used to find the cost, c, of the pizza is c/5 = $3.25.
An equation is a mathematical statement that shows that two expressions are equal. Equations use an equals sign (=) to show that the values of the expressions on either side of the sign are equal.
Equations can include variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division. The goal of solving an equation is to find the value of the variable that makes the equation true.
If they divide the cost of a meatball pizza evenly among 5 people and each person pays $3.25, then we can write the equation as
c/5 = $3.25
where c is the cost of the pizza
Plugging in the known value of p = $3.25, we get: c = 5($3.25) = $16.25.
So the cost of the meatball pizza at the Dancing Meatball is $16.25.

The measure of the angle BCD is 60 degrees.
What is the measure of angle BCD?Ok, remember that the sum of the interior angles of a triangle is always equal to 180°.
And we can write the top angle at C as:
(5x + 10) + C = 180°
C = 180 - 5x - 10
Then the sum of the interior angles gives:
3x + 3x + (180 - 5x - 10) = 180
Now we can solve that for x to get:
6x -5x - 10 = 180 - 180
x - 10 = 0
x = 10
Then the measure of BCD is:
BCD = 5x + 10
BCD = 5*10 + 10 = 60

How can 0.5 be expressed as fraction?
Step-by-step explanation:
changing 0.5 to fraction is 1/2
0.5 is equal to 1/2 as a fraction.
What is 0.5 as a fraction?Being able to quickly translate fractions between different forms, such as decimals and percentages, is a useful talent. You may learn how to change 0.5 from a decimal to a fraction by following the instructions in this guide.The first step in changing 0.5 into a fraction is to rewrite it as p/q, where p and q are both positive integers. To begin with, the fraction 0.5 might be represented as simply 0.5/1 in order to be considered one.The next thing we'll do is count how many fractional digits there are in 0.5 after the decimal point, which in this case is 1. The numerator and denominator of 0.5/1 are multiplied by 10 to the power of the number of digits after the decimal point, depending on how many digits are present. For example, we would multiply by 100 for 0.45 because it has two fractional digits, and by 1000 for 0.324 because it has three fractional digits. We will therefore in this instance multiply the numerator and denominator of 0.5/1 each by 10:0.5×10 /1×10=5 / 10
Finally, discover related factors and eliminate them to simplify the fraction, if possible:5 /1 0 = 1 /2 .

true or false: if u is mean independent of educ , then the average level of ability is the same regardless of the level of education.
False. If the mean of "u" (unobserved ability) is independent of education, it only means that the average level of ability is not affected by the level of education. It does not imply that the average level of ability is the same for all levels of education.
In economics, "u" is often used to represent unobserved ability or talent, which can affect an individual's income or job performance. If the mean of "u" is independent of education, it means that the average level of ability is not affected by the level of education, i.e., the mean of "u" is the same for all individuals regardless of their level of education.
However, it does not imply that the average level of ability is the same for all levels of education.
For example, individuals with higher levels of education may have higher levels of "u" on average, due to factors such as better access to resources, more opportunities for learning and development, or self-selection of individuals with higher levels of "u" into higher levels of education.
In such a case, the mean of "u" would still be independent of education, but the average level of ability would not be the same for all levels of education.

year. Auming that the car' value depreciated teadily from year to year, what wa it worth at the end of the third year?
The worth at the end of the third year is 15,400.
Depreciation:
The purchase value of an asset is the amount that it is purchased for. The value of the asset after a certain number of years is the difference between the purchase value and the accumulated depreciation.
There is a general formula to calculate Depreciation:
Depreciation Method = (Cost of an Asset – Residual Value)/Useful life of an Asset.
Given that Cost of an Asset=25000
Residual Value=2600
The useful life of an Asset=7
Now plug the given values in the above formula:
(25,000-2,600)/7=22,400/7=3,200
DM=3,200 which is calculated annually.
For the 3 years worth:

Mowing Andre's uncle's lawn paid better than the other two jobs.
The job that paid better compared to the others is mowing Andre's uncle's lawn. He earned $30 for 1 hour of work, which is more than the $10 he earned for mowing a neighbor's lawn for 1 hour or the $15 he earned each hour for mowing the community's lawn for 2 hours.
The thinking behind this is basic. The rate of pay for mowing Andre's uncle's lawn was higher than the rate of pay for the other two jobs.
This is still up in the air by isolating the sum earned by the number of hours worked.
For the uncle's lawn, the rate was $30/1 hour = $30 each hour.
For the neighbor's lawn, the rate was $10/1 hour = $10 each hour. Furthermore, for the community center's lawn, the rate was $30/2 hours = $15 each hour.

The concept of the integral is a fundamental part of calculus and it is used to calculate the area under a curve or the volume of a 3-dimensional object. In this context, we will be exploring the integral of a two-dimensional set in the R^2 plane.
For every two-dimensional set C contained in R^2 for which the integral exists, the function Q(C) is defined as the double integral of the function (x^2 + y^2) over the set C. The double integral is a mathematical tool for finding the total volume under a surface.
Let's consider the three sets C1, C2, and C3 and find Q(C1), Q(C2), and Q(C3).
C1={(x,y) : −1 ≤ x ≤ 1, −1 ≤ y ≤ 1}
Q(C1) = ∬C1 (x^2 + y^2) dxdy = ∫^1_{-1}∫^1_{-1} (x^2 + y^2) dxdy = ∫^1_{-1} [(x^2 + y^2)/2]^1_{-1} dx = 4.
C2 ={(x,y):−1≤x≤1,−1≤y≤1}

The probability of selecting a peanut butter cookie first is 8/29, since there are 8 peanut butter cookies and 29 total cookies of all variety in the bag. Then, the probability of selecting an oatmeal cookie after eating a peanut butter cookie is 8/28, since there are now only 28 cookies remaining in the bag and 8 of them are oatmeal cookies.
