The whole section is 9/4 unit.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
Mr.Parrillo’s class has adopted a section of a highway to keep clean.
1/3 of the section is 3/4.
To find the length of the whole section:
Multiply by 3.
So,
The length of the whole section = 3 (3/4)
The length of the whole section = 9/4

What is a rectangle?Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral, A closed, four-sided rectangle is a two-dimensional shape. A rectangle's opposite sides are equal and parallel to one another, and all of its angles are exactly 90 degrees.
Length is equal to 2 (2 + 3) the sum of the side lengths.
The sum of side length divided by (12) equals (2/5)
12 = 0.4(sum of side length) (sum of side length)
divide both sides by 0.4.
The height of the flag is calculated as side lengths plus length.
Height of flag: (30 – 12) = 18 feet
Therefore, the height of the flag is 18 feets.

The lines represented by the equations y= -1/3x+2and 5y+15x=-40
The two lines are neither parallel nor perpendicular to each other.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the two equations of the lines are y= -1/3x+2 and 5y+15x=-40.
y= -1/3x+2
5y+15x=-40.
5y = -15x - 40
y =-3x - 40/3
Here the slopes of the lines are,
m₁= -1 / 3
m₂ = -3
For the lines to be parallel the slopes should be equal and for the lines to be perpendicular the slopes should be inverse and reciprocal.
Here the slopes are neither equal nor have the inverse reciprocal.

.25x + 0.05y = 9, x + y = 25
Answer:
x = -4
y = 29
Step-by-step explanation:
Let's take our two equations and turn the decimals into fractions for simplicity's sake. We get:
x/4 + 5y/100 = 9 x + y = 25
Simplifying a bit gives us:
x/4 + y/20 = 9 x + y = 25
Now, we will take the first equation and multiply it by 20 to get rid of the fractions. We get:
5x + y = 9
We will rearrange numbers to give us an answer to y that we can substitute in. we get:
y = 9 - 5x
Then, we will plug this into our second equation giving us:
x + 9 - 5x = 25
Combining like terms and subtracting 9 from both sides gives us:
-4x = 16
Dividing by -4 gives us:
x = -4
Then, we can substitute this into our second equation giving us:
-4 + y = 25
We will add 4 to both sides giving us:
y = 29

For the interval estimation of μ when σ is assumed known, the proper distribution to use is the_____. a. standard normal distribution b. t distribution with n degrees of freedom c. t distribution with n − 1 degrees of freedom d. t distribution with n − 2 degrees of freedom
When estimating a population mean (μ) with a known population standard deviation (σ), the proper distribution to use is the standard normal distribution. So, correct option is A.
This is because the sampling distribution of the sample mean follows a normal distribution when the population standard deviation is known. The central limit theorem guarantees that the sample mean will be normally distributed with mean μ and standard deviation σ/√n, where n is the sample size.
The formula for constructing a confidence interval for μ when σ is known is:
CI = x' ± zα/2 * (σ/√n)
where x' is the sample mean, zα/2 is the z-score corresponding to the desired confidence level (α), σ is the population standard deviation, and n is the sample size.
Since the standard normal distribution has a mean of 0 and a standard deviation of 1, we can use z-scores to find the appropriate values for zα/2. This is why the standard normal distribution is used for interval estimation when σ is known.
In summary, the standard normal distribution is used for interval estimation of μ when σ is known because the sampling distribution of the sample mean is normally distributed when the population standard deviation is known.
So, correct option is A.

Write an equation that expresses the number of subscribers B in terms of n, the number of months the paper has been printed.a.B
this is a question of set of equations and solution is as follows,
Williamston Daily newspaper started printing newspaper.
Three years ago they had 5900 subscribers.
every month there is an increase of 66 new subscribers.
n is the number of months the paper has been printed.
so, the linear model will be
B= early subscriber + number of month × increments
B= 5900 + n × 66
B= 66 n + 5900
Example - subscribers after 3 months,
n = 3
= 66 x 3 +5900
