4y = x + 6 is the equation of the line using the slope value.
What is a line's slope?The steepness of a line segment is explained by the slope of the line. It is a ratio of the vertical x-axis coordinates and the y-axis coordinates. The classification of whether two lines are parallel or perpendicular depends on the slope value.
The parameters for the line segment are as follows, in accordance with the question:
The coordinate points (6, 3) and the slope of a line (1/4) are as follows: (x = 6; y = 3)
Using the line segment's standard equation now: y = mx + c
If (x, y) are coordinates, "m" is the slope, "c" is the y-intercept,
The following results are obtained by replacing the slope and y-intercept values in the formula:
y = mx + c
⇒ 3 = (1/4)(6) + c
⇒ c = 3 - 3/2 = 3/2
Consequently, c = (3/2) is the y-value. intercept's
by changing the slope value and y-intercept value in the line's equation:
y = (1/4)x + (3/2) = 4y = x +6
Consequently, 4y = x + 6 is the equation of the line using the slope value.

The perimeter of an equilateral triangle is 17 inches more than the perimeter of a square, and the side of the triangle is 8 inches longer than the side of the square. Find the side of the triangle ( Hint: An equilateral triangle has three sides the same length.)
Answers
The side of the triangle is 15 inches.
How to find the perimeter of a triangle and square?The perimeter of an equilateral triangle is 17 inches more than the perimeter of a square, and the side of the triangle is 8 inches longer than the side of the square.
Hence,
let
perimeter of the square = x inches
perimeter of an equilateral triangle = x + 17
Let
side of the square = y
side of the triangle = 8 + y
Therefore,
Perimeter of the square
x = y + y + y + y
x = 4y
Perimeter of the triangle
x + 17 = 8 + y + 8 + y + 8 + y
x + 17 = 24 + 3y
x - 3y = 7
Combine the equation,
x = 4y
x - 3y = 7
Therefore,
4y - 3y = 7
y = 7
x = 4(7)
x = 28
Therefore,
side of the triangle = 8 + y = 8 + 7 = 15 inches

3x + 6x + 10 + 8 = 180
Combine like terms,
9x + 18 = 180

Automated manufacturing operations are quite precise but still vary, often with distribution that are close to Normal. The width in inches of slots cut by a milling machine follows approximately the N(0.97,0.001)
N(0.97,0.001) distribution. The specifications allow slot widths between 0.9698
0.9698 and 0.9702
What proportion of slots meet these specifications?
Answers
The proportion of slots who meet these specifications is 15.86%.
We are given that the width in inches of slots cut by a milling machine follows approximately the N(0.97,0.001) distribution.
Also, the specifications allow slot widths between 0.9698 and 0.9702
Let X = width in inches of slots cut by a milling machine
The z-score probability distribution for normal distribution is given by;
Z = (X - μ) /σ ~ N(0,1)
where, μ = population mean width = 0.97
σ = standard deviation = 0.001
The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Now, Probability that the specifications allow slot widths between 0.9698 and 0.9702 is given by = P(0.9698 < X < 0.9702)
= P(0.9698 < X < 0.9702) = P(X < 0.9702) - P(X 0.9698)
P(X < 0.9702) = P [(X - μ) /σ < [tex]\frac{0.9702 - 0.97}{0.001}[/tex]] = P (Z < 0.2) =
P(X ≤0.9698) = P [(X - μ) /σ ≤ [tex]\frac{0.9698 - 0.97}{0.001}[/tex] ] = P (Z ≤ -0.2) = 1- P(Z < 0.2)
= 1 - 5793 = 0.4207
So, in the z table the P(Z x) or P(Z < x) is given. So, the above probability is calculated by looking at the value of x = 0.2 in the z table which has an area of 0.5793.
Therefore, P(0.9698 < X < 0.9702) = 0.5793 - 0.4207 = 0.1586
Hence, the proportion of slots who meet these specifications is 15.86%.

Numbers of lemons(x) | Total cost(y)

_?__ | $4.20
_?__ | $9.00
18 | _?__
Answers
Answer:
The constant of proportionality is $1.80
y = 1.80x
Step-by-step explanation:
The constant of proportionality is $1.80
An equation that relates the total cost, y, and the number of lemons, x, is
y = 1.80x
where,
y =Total cost
x = number of lemon
When x = 4
y = 1.80x
y = 1.80(4)
y = 7.2
y = $7.2
When y = $4.20
y = 1.80x
4.20 = 1.80x
x = 4.20 / 1.80
x = 2 1/3
x = 2 1/3
When y = $9.00
y = 1.80x
9.00 = 1.80x
x = 9.00 / 1.80
x = 5
x = 5
When x = 18
y = 1.80x
y = 1.80 × 18
y = 32.4
y = $32.4
Use this table to answer the following questions.If the number of gallons of gas is known, can you find the number of gallons consumed? Explain how this value would be calculated.

The table of values indicates a proportional relationship between the number of gallons of gas and the number of miles driven, therefore;
The number of miles driven, f(x) can be found from the number of gallons of gas consumed, x, using the equation; f(x) = 31•xWhat is a proportional relationship?A proportional relationship is one in which one variable, y, can be obtained from another variable, x, by multiplying x by a factor.
Please find attached a table showing the number of gallons of gas and the miles driven obtained from a similar question online
Let x represent the number of gallons of gas and let f(x) represent the number of miles driven
The difference between the consecutive terms of the first three values in the number of gallons and miles driven are each equal to 2 and 62 respectively
4 - 2 = 2 - 0 = 2
124 - 62 = 62 - 0 = 62
Therefore, given that the first difference is constant, the first three points have a linear relation, which gives;
Slope of the line = 62/2 = 31
Intercept = 0
Therefore;
f(x) = 31•x
Checking the fourth point, gives;
x = 10
f(10) = 31 × 10 = 310
The relationship between the miles driven, f(x), and the number of gallons is therefore a proportional relationship, which is presented as follows;
f(x) = 31•x
Therefore, if the number of gallons of gas, x, is known, the number of miles driven, f(x), can be found using the equation;

Diego and Stacy can paint a doghouse in 5 hours
Diego works twice as fast as Stacy
Let x be the number of hours it would take Diego to paint the doghouse and y be the number
Putting the given information mathematically
Diego and Stacy can paint a doghouse in 5 hours
x + y = 5hoursDiego works twice as fast as Stacy
x = 2yx + y = 5hours
Since x = 2y
2y + y = 5
3y = 5
y = 5/3
y = 1 1/3
from x = 2y
x = 2 * 5/3
x = 10/3
x = 3 1/3
1/3 hours is a fraction of hours. we convert it to minutes by multiplying by 60
= 1/3 * 60
= 20 minutes
Therefore it will take Diego 3 hours 20 minutes and Stacy 1 hour 20 minutes for them to complete a 5 hours work
If Diego works alone
Diego alone = 5 hours + Stacy's hours * 1/2
since Diego is twice faster than Stacy then Stacy's time will be halved
Diego alone = 5 hours + 80 minutes * 1/2
Diego alone = 5 hours + 40 minutes
Diego alone = 5 hours 40 minutes
if Stacy works alone
Stacy alone = 5 hours + Diego's hours * 2
Stacy alone = 5 hours + 3 hours 20 minutes * 2
Stacy alone = 5 hours + 6 hours 40 minutes

Answers
In my opinion, Report 1 is more persuasive than Report 2 due to the fact that the margin of error in Report 1 is narrower than in Report 2.
This is further explained below.
What is the margin of error.?Generally, we consider report one and report two
For Report
at 98% confidence interval = $64.35 to $83.59
Therefore, the Margin of error
M.E= $83.59 - $64.35
M.E = $19.24
For Report 2:
95% confidence interval = $58.37 to $71.93
Margin of error
M.E= $71.93 - $58.37
M.E= $13.56
Since Report 1 has a smaller margin of error than Report 2, I find Report 1 to be more convincing.
In conclusion, A report with a lower margin of error, in my opinion, is often more credible than one with a bigger one.
This is because more exact data indicates a report with a reduced margin of error.
To put it another way, information in a report with a lower margin of error is more likely to be correct than information in a report with a higher margin of error.
