Kiran collects data about the number of trees on school property and the average standardized test scores for those schools. Kir

an says, "The scatter plot between the number of trees on a school property and student standardized tests scores shows a strong and positive correlation. An increase in the number of trees on school property causes the students to score better on standardized tests." What does it mean for the relationship between the variables when the correlation is strong in this situation? What does it mean for the relationship between the variables when the correlation is positive in this situation? What is wrong with the last sentence of Kiran's statement? Explain your reasoning.

Answer:

Although the variables are related, there is not likely a causal relationship. Trees probably do not directly influence test scores as much as other factors that might be related.

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel
Murrr4er [49]

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.

Question
Goryan [66]

Given:

(2, 4) and (3, 3) are on the line.

To find:

The equation of line in point slope form.

Solution:

If a line passes through a point (x_1,y_1) with slope m, then the point slope form of the line is

y-y_1=m(x-x_1)

(2, 4) and (3, 3) are on the line. So, slope of the line is

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{3-4}{3-2}

m=\dfrac{-1}{1}

m=-1

The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is

y-4=-1(x-2)

Therefore, an equation of the line in point slope form is y-4=-1(x-2).
