What is a linear equation?A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
How do you identify a linear equation?A mathematical equation is said to be linear if it has the formula y=mx+b, where m denotes the slope and b the y-intercept.
Why is it called linear equation?An algebraic equation is said to be linear if each term has an exponent of 1, and if the equation is graphed, it always produces a straight line. This is the basis for its designation as a "linear equation."
the linear equation:
\(17/20 = j + 11/20\\ 17/20 - 11/20 = j + 11/20 - 11/20\\ (17 - 11)/20 = j\\ 6/20 = j\)

There are 20 people trying out for a team. How many ways can you make randomly select for people to make a team?
Answers
There are 15,504 ways to randomly select a team of 5 people from a group of 20 people
If there are 20 people trying out for a team, the number of ways to select a team of n people can be calculated using the formula for combinations, which is:
C(20, n) = 20! / (n! * (20 - n)!)
where C(20, n) represents the number of ways to select n people from a group of 20 people.
For example, if we want to select a team of 5 people, we can plug in n = 5 and calculate:
C(20, 5) = 20! / (5! * (20 - 5)!) = 15,504
Therefore, there are 15,504 ways to randomly select a team of 5 people from a group of 20 people. Similarly, we can calculate the number of ways to select teams of different sizes by plugging different values of n into the formula for combinations.

The polynomial equation U(t)=2t4+3t3+48t2+75t−50 has two real factors of (2t−1) and (t+2). Select the two complex factors
Answers
The two complex factors of the polynomial equation U(t) are derived from the remaining quadratic expression 2t² - 3t + 19.
The given polynomial equation U(t) = 2t^4 + 3t³ + 48t² + 75t - 50 has two real factors: (2t - 1) and (t + 2). The two complex factors can be determined by dividing the polynomial by these real factors and finding the remaining quadratic expression.
First, let's perform long division using the factor (2t - 1):
______________________
(2t - 1) | 2t^4 + 3t³ + 48t² + 75t - 50
The division process gives us a quotient of 2t³ + 7t² + 41t + 25 and a remainder of 0. Now, we can factorize the quotient expression: 2t³ + 7t² + 41t + 25.
Next, let's perform long division using the factor (t + 2):
________________________
(t + 2) | 2t³ + 7t² + 41t + 25
The division process gives us a quotient of 2t² - 3t + 19 and a remainder of 0. Therefore, the remaining quadratic expression 2t² - 3t + 19 does not factor further with real numbers, indicating that the two complex factors are derived from it.

under which of the following conditions is it preferable to use stratified random sampling rather than simple random sampling?
Answers
Answer:
The population can be divided into strata so that the individuals in each stratum are as much alike as possible.
Step-by-step explanation:
In short, if you can group the population into subgroups and are interested in their sub properties, then use stratified random sampling. If not, and interested only in the entire population as a whole, then use simple random sampling.
Simple random sampling, as the name suggests, is simply sampling randomly from the population. It doesn't make any assumptions of sub-classifications about the given population and is only interested in sampling the population as a whole representative.
Stratified random sampling, as the name suggests, does sampling on strata( parts or subgroups divided in the population). The sampling then is done from each group proportionate to the group's size versus the population size.
One example is when you've got red, green and blue colored balls as the population and you want to sample the population based on colors, then the colored groups are strata and thus, the sampling will be done on subgroups and such type of sampling will be called as stratified random sampling.
Simple random sampling doesn't care about sub-properties in the population. It consider the population as whole and doesn't differentiate classes in the population, unlike stratified random sampling.

5(y+25)=−13 what is y
Answers
Answer:
y = -27.6
Step-by-step explanation:
To solve for y, you need to isolate the variable on one side of the equation. \(5(y+25)=-13\) ⇒ \(y + 25 = -2.6\) ⇒ \(y = -27.6\).
Answer:
-27.6
Step-by-step explanation:
\(5(y + 25) = -13\)
First, distribute the problem.
\(5y + 125 = -13\)
Secondly, subtract 125 from -13 and 125.
\(125 - 125 = 0\)
\(-13 - 125 = -138\)
Now, we are left with 5y = -138.
Lastly, we divide -138 by 5.
\(-138 / 5 = -27.6\)
Therefore, y is -27.6.

Suppose your multiple regression output summary from computerized software indicated that there was a significant association between your outcome and response variables while controlling for the effects of two different co-variables. However, your R2 calculation was only 11.5%. What can be interpreted from the results
Answers
Based on the information provided, it appears that the regression model has found a statistically significant relationship between the outcome variable and the response variables while controlling for the effects of the two co-variables.
However, the R2 value of only 11.5% suggests that the model is explaining only a small portion of the variability in the outcome variable. This may indicate that there are other important factors that are not being accounted for in the model. It is also possible that the co-variables included in the model are not strong predictors of the outcome variable. Further investigation and analysis may be needed to fully understand the relationship between the variables and to improve the predictive power of the model.

Myra is putting together a puzzle such that every 5 days she places one quarter of the remaining pieces into the puzzle. If she started with a 800 piece puzzle, how many pieces are left to be placed after 23 days? Show the work that leads to your answer
Answers
Given:
Initial number of pieces Myra have = 800.
Every 5 days she places one quarter of the remaining pieces into the puzzle.
To find:
The number of remaining pieces after 23 days.
Solution:
Initial number of pieces Myra have = 800.
Every 5 days she places one quarter of the remaining pieces into the puzzle.
It means, she will place the puzzles on 5,10,15,20,25,.. days. she will place the puzzle 4 times before 23 days.
The number of remaining pieces decreasing by \(\dfrac{1}{4}\).
Formula for number of remaining pieces is
\(y=a_0(1-r)^t\)
where, \(a_0\) is the initial value, r is decreasing rate and t is time.
Putting \(a_0=800,r=\dfrac{1}{4}\) and t=4, we get
\(y=800(1-\dfrac{1}{4})^4\)
\(y=800(\dfrac{3}{4})^4\)
\(y=800(0.75)^4\)
\(y=800(0.31640625 )\)
\(y=253.125\)
Approximate the value to the nearest whole number.
\(y\approx 253\)
Therefore, the number of remaining pieces is 253.
the graphs below have the same shape. what is the equation of the red graph?

Find the length of the slant height of A F in this square pyramid. Round you answer to the nearest tenths.
GIVE RIGHT ANSWER AND I WILL GIVE YOU BRAINLIEST!
Answers
Answer:
Slant height = 10.2 cm
Step-by-step explanation:
The altitude (10 m) from the top of the pyramid extending to the center of the base forms a right triangle with half of the base length (4/2, which is 2 m) and the slant height.Thus, we can find the slant height using the Pythagorean theorem, which is given by:
a^2 + b^2 = c^2, where
a and b are the shortest sides of the triangle called legs,and c is the longest side called the hypotenuse.Thus, we can plug in 2 and 10 for a and b to solve for c, the slant height rounded to the nearest tenth:
Step 1: Plug in 2 and 10 for a and b and simplify:
2^2 + 10^2 = c^2
4 + 100 = c^2
104 = c^2
Step 2: Take the square root of both sides and round to the nearest tenth to find c, the length of the slant height:
√(104) = √(c^2)
10.19803903 = c
10.2 = c
Thus, the slant height is about 10.2 cm.
