Answer:

y = 1/4x + 4

Step-by-step explanation:

Knowledge Needed

Slope: The amount the y-value changes on a constant line when the x-value increases by 1.

Slope Formula:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

y-intercept: When the line has a x-value of , or when it intersects the y-axis.

Slope-Intercept Form: y = mx+b

m is slope, b is y-intercept.

Leave y and x as variables so you can graph it.

Question

First, plug the points into the slope formula.

[tex]\frac{3-5}{-4-4}[/tex]

[tex]\frac{-2}{-8}[/tex]

1/4

y = 1/4x + b

Solve for b:

Use any of the 2 points to plug back in. I'll use (4,5).

We have: y = 1/4x + b

(5) = 1/4(4) + b

5 = 1 + b

5 - 1= 1 - 1 + b

b = 4

y = 1/4x + 4

The correct answer is option b). Multiple regression is described best as "using the brain volume, the body height, and the body weight to predict the IQ score of an individual."

Multiple regression is a statistical technique that involves using two or more predictor variables to predict a single response variable. In this case, the response variable is the IQ score and the predictor variables are the brain volume, the body height, and the body weight. By using multiple predictor variables, multiple regression allows you to analyze the combined effect of these variables on the response variable, as well as to identify which variables have the greatest influence on the response variable.

What is Pythagoras theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The length of the diagonal of a square is calculated using the following Pythagoras theorem.

[tex]d^2=l^2+l^2\\[/tex]

Where:

d represents the length of the diagonal

l represents the side length of the square

So, we have:

[tex]d^2=3^2+3^2[/tex]

An explanatory variable is an illustration of an independent variable. There isn't much of a distinction between the two, though.

When a variable is completely unaffected by any other variables, it is said to be independent. Any variable that cannot be identified as an independent variable is an explanatory variable.

The outcome of an experiment in which the explanatory variable was altered is the response variable. Many different variables can be used to explain the variation of this variable. The phrases response variable, dependent variable, and outcome variable are sometimes used synonymously.

As per the given function, asymptotes of the hyperbola will be at x = -4 and 6.

The term hyperbola id defined as a plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant

Here we have given the following function,

f(x) = 7/x² - 2x - 24

Now, we have to calculate the asymptotes as follows,

Let us consider that f(x) = ∞ and it is not defined

=> x²- 2x - 24 = 0

Now, we have to factories the expression, then we get

=> x² - (6-4) x - 24 = 0

When we simplify the given expression, then it looks like,

=> x² -6x + 4x -24 = 0

Therefore, the value of x is calculated as

9 ones, 9 tens  99.77 is equal to 7 tenths 7 hundredths.

The place value of the digits that come after a decimal point is defined in mathematics as tenths and hundredths. When we count from right to left, the place values of the digits in a number are ones, tens, hundreds, and thousands.

The columns are labelled tenths, hundredths, thousandths, and so forth from left to right following the decimal point. The tenths column is the first digit following the decimal point. The column for hundredths is the second digit following the decimal point. The column for thousandths is the third digit following the decimal point.

The digit after the decimal point, or in the tens place, is known as the divisor. The first digit to the right of the decimal place is the tenths place digit.

9 tens = 9 x 10 = 90

9 ones =9 x 1 = 9

7 tenths = 7x 1/10 =0.7

7 hundredths = 7 x 1/100 = 0.07

When a number has two digits, it is called a 2-digit number.

2-digit numbers have two digits and range from 10 to 99.

They are unable, to begin with, zero since it will then be regarded as a single-digit number.

Any number between 1 and 9 can be used as the digit in the tens place.

For instance, the numbers 45, 78, and 12 have two digits.

When it comes to two-digit numbers and their reversal, there are two common logics.

The graph of the function y tan 3 4x has a vertical asymptote at x = π/12, which means that as x approaches π/12 from either side, the output of the function increases without bound.

The graph of the function y tan 3 4x has a vertical asymptote at x = π/12, which means that as x approaches π/12 from either side, the output of the function increases without bound. This is because when x = π/12, the denominator of the tangent function (3/4x) is 0, which creates an undefined value. As a result, the output of the function increases without bound as x approaches π/12. This is why x = π/12 is an asymptote of the graph. Asymptotes can be thought of as boundary lines, beyond which the graph of the function cannot cross. In this case, the graph of y tan 3 4x will approach the vertical asymptote of x = π/12, but will never cross it.

The probability that a randomly generated bit string of length four contains at least two consecutive zeros, given that the first bit is a 1, is 1/8.

The probability of a randomly generated bit string of length four containing at least two consecutive zeros, given that the first bit is a 1, can be calculated by considering all of the possible combinations of four bits that meet this criteria. There are 8 possible combinations of four bits that contain two consecutive zeros and the first bit being a 1, so the probability of such a combination being chosen is 1/8. The probability of each individual bit being a 0 or a 1 is assumed to be the same, so the probability of any given combination is equal. Therefore, the probability of a randomly generated bit string of length four containing at least two consecutive zeros, given that the first bit is a 1, is 1/8.

P(2 consecutive 0s, given first bit is 1)

= (# of possible combinations with 2 consecutive 0s, given first bit is 1) / (total # of possible combinations)

y = mx and y - 0 = m(x - 0) are the equations for a line passing through the origin with a slope of m.

To find the equation in point slope form for the given table of height of a plant first we have to find the slope.

Example 1 : Let's say you have one triangle, ∆ABC with side lengths 5 and 10 and the angle included between those two sides is 30 degrees. If you have a second triangle, ∆DEF that also has side lengths 5 and 10 with a 30 degree angle in between, then by the SAS Postulate ∆ABC is similar to ∆DEF.

Horizontal asymptotes are horizontal lines that a graph of a function approaches as it goes towards positive or negative infinity. To find them, look at the degree of the numerator and denominator of a function. If the degree of the numerator is less than the degree of the denominator, the graph will approach the x-axis asymptote. If the degree of the numerator is equal to the degree of the denominator, the graph will approach the y-axis asymptote. Vertical asymptotes are vertical lines that a graph of a function approaches as it goes towards positive or negative infinity. To find them, solve for all x-values where the denominator equals 0.
