The table shows a country’s average fuel consumption for light duty vehicles for several years. Let XP the number of years since 1985 so that executes five cents for 1990 and so forth. Find the linear regression model for the status. What does slope and regression model represent
Using linear function concepts, it is found that:
The slope is of 0.172 means that the fuel economy increases by 0.172 mpg each year.The intercept of 17.04 means that the fuel economy was of 17.04 mpg in 1985.What do the slope and the intercept of a linear function represent?The slope-intercept representation of a linear function is:
y = mx + b.
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, we will use a calculator from the points on the table to build a linear function of best-fit. The points are given as follows:
(5, 17.9), (10, 18.7), (15, 19.7), (20, 20.5), (25, 21.3).
Then the function is:
y = 0.172x + 17.04.
Then:
The slope is of m = 0.172, meaning that each year, the fuel economy increases by 0.172 mpg.The intercept of b = 17.04 was the fuel economy in 1985.What is the missing information?The table is missing, and is given by the image at the end of the answer.

A man's taxable income is $3.060 If tax is paid at 12%. How much is the man's net income
A man's taxable income is $3060 if tax is paid at 12%, then the man's net income is $3477.27
The taxable income = $3060
The tax percentage = 12%
Income tax is the a type of tax impose on income generated by businesses and individuals by the government
Consider the net income as x
Then,
12% of the income = x×(12/100)
Therefore the equation will be
x - x×(12/100) = 3060
x(1-(12/100) = 3060
x(1-0.12) = 3060
0.88x = 3060
x = 3060/0.88
x = $3477.27
Hence, a man's taxable income is $3060 if tax is paid at 12%, then the man's net income is $3477.27

25.42 marked down by 33%
25.42 marked down by 33 % is 17.0314.
This is a question of percentages.
Percentage
A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Percentages have no dimension. Hence it is called a dimensionless number.
33 % of 25.42 is given by:-
(33/100)*(25.42) = (33*25.42)/100 = 838.86/100 = 8.3886
25.42 marked down by 33 % = 25.42 - 8.3886 = 17.0314.

Jillian and Nikki each filled their cars with gasoline. The graphs below show the amount of gas in each car and the miles driven since filling the tank. A graph titled Jillian's Car has miles driven on the x-axis, and gallons of gas left on the y-axis. A line goes through (0, 22) and (100, 16). A graph titled Nikki's Car has miles driven on the x-axis and gallons of gas left on the y-axis. A line goes through points (0, 20) and (100, 16). Which statement is supported by the graphs? Jillian’s car holds more gasoline and gets better gas mileage. Nikki’s car holds more gasoline and gets better gas mileage. Jillian’s car holds more gasoline, but Nikki’s car gets better gas mileage. Nikki’s car holds more gasoline, but Jillian’s car gets better gas mileage.
The statement that is best supported by the graph is; Jillian's car holds more gasoline, but Nikki's car gets better gas mileage.
How to Interpret Linear Graphs?The total amount of gasoline each car tank can hold is shown on the left of each graph on the y-axis.
Jillian's car holds 22 gallons.
Nikki's car holds 20 gallons.
Jillian's car holds more gasoline.
Now we need to see which car gets better gas mileage. Getting better gas mileage means you can go farther with each gallon of gas.
With Jillian's car, after using 22 gallons of gas, you have gone 350 miles, and the gas tank is empty.
350 miles with 22 gallons is 350/22 = 15.9 miles per gallon.
With Nikki's car, you start with only 20 gallons. By the time you drive 350 miles, you still have some gas left. Not only did you start with less gas, 20 gal vs. 22 gal, but after driving the same distance, 350 miles, there is still some gas left in the tank, 6 gallons.
That means Nikki's car used 20 - 6 = 14 gallons to drive 350 miles. 350/14 = 25 miles per gallon.
The more miles per gallon you get, the better the mileage. Thus;
25 miles per gallon is better mileage than 15.9 miles per gallon.
Nikki's car has a smaller gas tank, but it gets better mileage.

Change 23 out of 25 to a percentage
This how we change 23 out of 25 to a percentage
The numerator of a question is the number that appears above the bar; in this case, the numerator is 23.
The denominator is the number beneath the bar, and in this question, it is 25.
To calculate the value of a fraction, divide the numerator by the denominator.
Therefore, we must divide 23 by 25.
23/25 = 0.92
To determine the percentage, multiply the outcome by 100.
The percentage value will be obtained by multiplying 0.92 by 100.
0.92 x 100 = 92%
As a result, 92% is the answer to the question.

The frequency of the 10 inch violin string will be 630 cycles per second or Hertz if the violin string 14 inches long vibrates at a frequency of 450 cycles per second.
As per the question statement, A violin string 14 inches long vibrates at a frequency of 450 cycles per second and we are supposed to find out the frequency of a 10-inch violin string.
We should be knowing that the length of a violin string varies inversely as the frequency of its vibrations.
f = m/l, where "f" is the frequency and "l" is the length and "m" is the constant number
450 = m / 14
m = 6300

Expand and simplify the expression using properties of operations. 8(3x−7)
The expression 8 ( 3x - 7 ) when expanded gives 24xx - 56.
The cornerstone of mathematics is the theory of operations; we use it to compute and remember fundamental truths. The subsequent three characteristics are applied to addition and multiplication: Commutative Property, Associative Property, and Distributive Property.
The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.
Consider the expression 8( 3x - 7 ),
Let's say y is equal to 8( 3x - 7 ).
By using the distributive property:
y = 8 × 3x - 8 × 7
y = 24x - 56
Therefore,
8( 3x - 7 ) = 24x - 56
Therefore, when the expression 8( 3x - 7 ) is expanded we obtain the expression 24x - 56.

4. Find “a” so that the parabola y = ax² + 3x + 11 goes through the point (3,2).
Answer:
a = - 2
Step-by-step explanation:
since the point (3, 2 ) lies on the parabola, then it makes the equation true.
substitute x = 3, y = 2 into the equation and solve for a
y = ax² + 3x + 11
2 = a(3)² + 3(3) + 11
2 = 9a + 9 + 11
2 = 9a + 20 ( subtract 20 from both sides )
- 18 = 9a ( divide both sides by 9 )
- 2 = a
Answer:
a = -2
Step-by-step explanation:
Given quadratic equation:
[tex]y=ax^2+3x+11[/tex]
In order to find "a", substitute the given point on the curve (3, 2) into the equation and solve for a:
[tex]\begin{aligned}y&=ax^2+3x+11\\\textsf{Substitute $(3,2)$} \implies 2&=a(3)^2+3(3)+11\\2&=9a+9+11\\2&=9a+20\\2-20&=9a+20-20\\-18&=9a\\9a&=-18\\\dfrac{9a}{9}&=\dfrac{-18}{9}\\\implies a&=-2 \end{aligned}[/tex]

Substitute the values of a and b to complete the solutions.
x = a + bi
x = a - bi
The solutions of the quadratic equation x² = 16x - 65 are:
x = 1/2 + 1/32i
x = 1/2 - 1/32i
What is the solution?We know that a quadratic equation is an equation that is of the sort ax^2 + bx + c = 0. Hence, the equation would be solved and it could have a complex root. By this I mean that the root of the equation could be a complex number as we have in the case of the equation here.
x² = 16x - 65 = 0
x² - 16x + 65 = 0
When we solve by the formula method;
x = -b ±√b^2 - 4ac/2a
x = -(-16) ±√(-16)^2 - 4 (1) (65)/2(16)
x = 16 ±√256 - 260/32
