A general proportional relation is written as:

y = k*x

You can see that it goes through the origin because when we evaluate in x = 0, we get:

y = k*0 = 0

So it passes through (0, 0).

The value "k" has several names, unit rate is the one given here, but it is generally called the "constant of proportionality"

It is also called the slope (like in a linear equation with an y-intercept equal to 0).

Or the rate of change or gradient, which are equivalent terms that particularly in the case of linear equations are equal to the slope (but not for other functions).

The line is:

Correct choice is D

The predicted grade for a student with 11 absences can be calculated using the equation y = mx + b, where y = predicted grade, m = the slope of the linear regression line, x = the number of absences, and b = the y-intercept. The predicted grade for a student with 11 absences is 79.5.

The linear regression equation is used to predict the value of a dependent variable (y) based on the value of an independent variable (x). The equation takes the form y = mx + b, where m is the slope of the regression line and b is the y-intercept. To calculate the predicted grade for a student with 11 absences, we first need to determine the value of m and b. This can be done by plotting the data points on a graph and calculating the slope and y-intercept of the regression line. Once we have the values of m and b, we can plug them into the linear regression equation. For example, if the slope is -0.5 and the y-intercept is 90, then the predicted grade for a student with 11 absences would be y = (-0.5 * 11) + 90 = 79.5. In this way, the linear regression equation can be used to predict the grade of a student based on the number of absences.

The equation will be w = 40b

To find the total weight (w) of the soil in pounds when Yuki stacks b bags, you can use a simple linear equation. Each bag weighs 40 pounds, so the equation will be: w = 40b

This equation shows that the total weight (w) of the soil in pounds is equal to the number of bags (b) multiplied by the weight of each bag (40 pounds).

The above answer is based on the information below as seen in the picture;

Answer= 27/8

Answer:

y = 0

Step-by-step explanation:

x + 2y = 2 ( subtract 2y from both sides )

x = 2 - 2y → (1)

x = - 4y + 2 → (2)

substitute x = 2 - 2y into (2)

2 - 2y = - 4y + 2 ( add 4y to both sides )

2 + 2y = 2 ( subtract 2 from both sides )

2y = 0 , then

y = 0

Answer:

54 = 2×3^3

Step-by-step explanation:

Factor the following integer:

54

Hint: | Is 54 divisible by 2?

The last digit of 54 is 4, which means it is even. Therefore 54 is divisible by 2:

54 = 2 27:

54 = 2×27

Hint: | Now try to factor 27. Is 27 divisible by 2?

27 is not divisible by 2 since 27 is odd and 2 is even:

54 = 2×27 (27 is not divisible by 2)

Hint: | Is 27 divisible by 3?

The sum of the digits of 27 is 2 + 7 = 9, which is divisible by 3. This means 27 is divisible by 3:

27 = 3 9:

54 = 2×3×9 (9 is not divisible by 2 since 27 is not)

Hint: | Now try to factor 9. Is 9 divisible by 3?

9 = 3 3, which means 9 is divisible by 3:

9 = 3 3:

54 = 2×3×3×3 (3 is not divisible by 2 since 9 is not)

Hint: | Now try to factor 3. Is 3 prime?

No primes less than 3 divide into it. Therefore 3 is prime:

54 = 2×3×3×3

Hint: | Express 54 as a product of prime powers.

There is 1 copy of 2 and 3 copies of 3 in the product:

The probability for events A and B will be 5/18.

Two dice are tossed.

Event A: The first die is a 5 or 6

Event B: The second die is not a 1

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

The probability for event A is calculated as,

P(A) = 2/6

P(A) = 1/3

The probability for event B is calculated as,

P(B) = 5/6

The probability for events A and B is calculated as,

P(A and B) = P(A) x P(B)

P(A and B) = 1/3 x 5/6

P(A and B) = 5/18

You would expect to find a negative correlation between rainfall and sales of sunscreen, as more rain typically means fewer people buying sunscreen.

Rainfall and sales of sunscreen would have a negative correlation, as more rain typically means fewer people buying sunscreen. This is because when it rains, typically people do not go out in the sun, so they do not need to purchase sunscreen. Additionally, when it rains, the UV rays are blocked, so people do not feel the need to buy sunscreen to protect their skin. Therefore, when it rains, the sales of sunscreen typically decrease. On the other hand, when it is sunny, people are more likely to go outside and purchase sunscreen to protect their skin from the sun’s harmful UV rays. Therefore, the more rain there is, the lower the sales of sunscreen will be and vice versa.

Answer:

-17

Step-by-step explanation:

Answer:

x = - 1 , x = 19

Step-by-step explanation:

x² - 18x = 19

to complete the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(- 9)x + 81 = 19 + 81

(x - 9)² = 100 ( take square root of both sides )

x - 9 = ± \(\sqrt{100}\) = ± 10 ( add 9 to both sides )

x = 9 ± 10

then

x = 9 - 10 = - 1

x = 9 + 10 = 19
