Using linear function to solve this problem, for every 1 gallon of gas, Francisco travelled 27.9 miles

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2. A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. where m is slope of the line and b is the y - intercept

We can use the data given in writing out our equation

390.6 = 14x

If 14 gallons = 390.6 miles

 1 gallon = x miles

x = 390.6 / 14

x = 27.9 miles

To find the probability distribution for Y, the number of errors detected by the auditor, we can use the binomial distribution formula. The binomial distribution is used when there are only two possible outcomes, success or failure, and each trial is independent.

In this case, the probability of success (detecting an error) is 5% or 0.05, and the probability of failure (not detecting an error) is 1 - 0.05 = 0.95.

a. To find the probability distribution for Y, we can use the formula for the binomial distribution:

P(Y = y) = (nCk) * p^k * (1-p)^(n-k)

where n is the number of trials (3 in this case), k is the number of successes (errors detected), p is the probability of success (0.05), and (nCk) is the combination formula.

For y = 0:
P(Y = 0) = (3C0) * (0.05)^0 * (0.95)^(3-0) = (1) * (1) * (0.95)^3 = 0.857375

For y = 1:
P(Y = 1) = (3C1) * (0.05)^1 * (0.95)^(3-1) = (3) * (0.05) * (0.95)^2 = 0.135375

For y = 2:
P(Y = 2) = (3C2) * (0.05)^2 * (0.95)^(3-2) = (3) * (0.05)^2 * (0.95)^1 = 0.007125

For y = 3:
P(Y = 3) = (3C3) * (0.05)^3 * (0.95)^(3-3) = (1) * (0.05)^3 * (0.95)^0 = 0.000125

So the probability distribution for Y is:
Y = 0 with probability 0.857375
Y = 1 with probability 0.135375
Y = 2 with probability 0.007125
Y = 3 with probability 0.000125

b. To construct a probability histogram for p(y), you can create a bar graph where the x-axis represents the number of errors detected (Y) and the y-axis represents the probability (P(Y = y)). Each bar will have a height corresponding to the probability.

c. To find the probability that the auditor will detect more than one error, we need to calculate the sum of the probabilities for Y = 2 and Y = 3:

P(Y > 1) = P(Y = 2) + P(Y = 3) = 0.007125 + 0.000125 = 0.00725

Therefore, the probability that the auditor will detect more than one error is 0.00725.

The simplified expression is  \(12u^8\).

What is simplification?

Simplifying an expression is just another way to say solving a math problem. When you simplify an expression, you're basically trying to write it in the simplest way possible. At the end, there shouldn't be any more adding, subtracting, multiplying, or dividing left to do. For example, take this expression: 4 + 6 + 5.

Here the given expression is ,

=> \(-2u^5(-6u^3)\)

Now simplifying the expression,

=> \(-2\times -6 \times u^5 \times u^3\)

=> 12\(u^{5+3}\)

=> \(12u^8\)

In mathematics, the place value chart is a tool that helps students understand the value of digits in a number. It is a visual representation of how digits are grouped and arranged to represent numbers. The place value chart is arranged in columns, with each column representing a different place value.

The place value chart starts with the ones place, also called units place. This is the rightmost column and it represents the ones digit in a number. The next column is the tens place, which represents the tens digit in a number. The hundredth place represents the hundreds digit and so on. Each column is ten times larger than the previous one.

A place value chart can be used to understand the value of a digit in a number.

Place value chart also helps to understand decimal numbers, which are numbers that have a decimal point. The decimal point separates the whole numbers from the fractional numbers. Each place to the right of the decimal point represents a smaller value.

Public bodies do not have the unlimited right to determine which offeror is the "lowest responsible bidder".

Instead, public bodies have the absolute right and discretion to award contracts for construction which are in the best interests of the taxpayers. They are responsible for ensuring that they comply with the law and regulations when determining which offeror is the lowest responsible bidder.

What is the principle of the lowest responsible bidder?

The lowest responsible bidder principle states that the lowest bidder who can demonstrate their capability of effectively fulfilling all contractual responsibilities is awarded the contract.

It refers to the offeror who can offer the best value for money while still meeting the requirements of the tender specifications.

However, the public body cannot simply award the contract to the lowest bidder without determining whether they are responsible for meeting all of the requirements of the contract.

In this regard, the public body may consider a number of factors such as the offeror's experience, capacity, and financial capability when determining whether they are responsible enough to be awarded the contract.

It is essential to note that the public body should comply with all laws, regulations, and requirements when determining the lowest responsible bidder.

This is because they are responsible for ensuring that taxpayer dollars are used in the best interests of the public, and awarding contracts to offerors who are not capable of meeting their contractual obligations can lead to waste, fraud, or abuse of public funds.

Answer:

8. x=18  9. x=33   10. x=65  11. x=19  12. x=59

Step-by-step explanation:

8.  The angles are essentially vertical so they have to be equal to each other.

42=2x+6   subtract 6 from both sides  36=2x   x=18

9.  These angles are supplementary and equal 180 when added together.

98+(3x-17)=180  subtract 98 and add 17 to both sides  3x=99  x=33

10.  Angles are essentially vertical so they are equal to each other.

2x+2=3x-63  add 63 to both sides subtract 2x from both sides  65=1x

11.  Angles are supplementary so they equal 180 when added together.

112+(4x-8)=180 subtract 112 and add 8 to both sides   4x=76   x=19

The condition that requires further analysis of the data  for slope inference is the independence of errors.

In this scenario, we have to determine the condition that requires further analysis of the data. We know that there are five conditions that need to be satisfied to perform the linear regression.

The five conditions are: Linearity, Homoscedasticity, Normality of residuals, Independence of errors. And the last one is: Independence of errors is the fifth condition that requires further analysis of the data to confirm that it is satisfied or not. The independence of errors condition is that there should be no pattern in the residuals.

Residuals are the differences between the actual values and the predicted values. The independence of errors is important because it ensures that the errors are random and not influenced by any other variable.

The independence of errors condition can be checked by plotting the residuals against the predicted values. If there is a pattern in the residuals, then the independence of errors condition is not satisfied. So, in order to satisfy the fifth condition for slope inference, the independence of errors condition must be satisfied.

Step-by-step explanation:

An inequality that represents the situation is s > 140.

Let's use "s" to represent the number of milligrams of sodium in a serving.

Since a serving of food does not qualify as low sodium if it contains more than 140 milligrams of sodium, we can write the inequality:

s > 140

This inequality reads "s is greater than 140", indicating that any value of "s" that is greater than 140 milligrams of sodium per serving does not qualify as low sodium.

To graph this inequality, we can represent "s" on the vertical axis and mark the value of 140 with a dashed line.

Since the inequality is greater than 140, we shade the area above the line to represent all the possible values of "s" that do not qualify as low sodium.

The resulting graph would look like given in the attached image.

The equation of the straight line perpendicular to the line 3x - 6y = - 8 is y-2x+6=0 and of line parallel to the line 3x - 6y = - 8 is y=0.

The general equation of a straight line is -

y=mx+c

where -

m is slope of line which tells the unit rate of change of y with respect to x.

c is the y - intercept i.e., the point where the graph cuts the y axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

\(y=\frac{-A}{B} x-\frac{C}{B}\)

Given that: -

\(3x-6y=8\\\\6y=3x-8\\\\y=\frac{1}{2}x-\frac{4}{3}\)

then,

\(m=\frac{1}{2}\\\\c=\frac{4}{3}\)

For a parallel line,

\(m=\frac{1}{2}\\and,(4,2)\)

\(y-y_{1}=m(x-x_{1})\\\\y-2=\frac{1}{2}(x-4)\\\\2y-4=x-4\\\\y=\frac{x}{2}\)

The equation of parallel line is y=0.5x

For a perpendicular line

\(m=2\\\\y-2=2(x-4)\\\\y-2=2x-8\\y-2x=-6\\y-2x+6=0\\\)

Therefore, the equation of the line perpendicular to the line 3x - 6y = - 8 is y -2x+6=0 and of line parallel to the line 3x - 6y = - 8 is y = 0.5x.
