Answer:
Step-by-step explanation:
Area of a trapezium is the average of the parallel sides times the distance between them.
If we subtract 15 units from each of the parallel sides, we end up with a triangle that has two sides of 8 units and one of 10 units. One of the 8 unit sides is the base and we need to find the height h which is perpendicular to this base.
Let the base be split into two segments, call one A, the other will be 8 - A
From Pythagoras.
10² - A² = h² = 8² - (8 - A)²
10² - A² = 8² - (8 - A)²
100 - A² = 64 - (64 - 16A + A²)
100 - A² = 64 - 64 + 16A - A²
100 = 16A
A = 6.25
h = √(10² - 6.25²)
h = √60.9375
A = ½(15 + 23)√60.9375
A = 148.31870246... ≈ 148.3 cm²
Let height of house be x.
Oak tree = 120 + x
Also given,
Oak tree = 2.5x
120 + x = 2.5x
1.5x = 120
0.3x = 24
3x = 240
x = 80
Hence, the height of the house is 80 ft.

Predictor variable: proximity from primary residence to farmland (in miles) outcome variable: animal rights opinion (scale from 0-50) correlation coefficient is the appropriate inferential statistic.
What is a predictor and response variable?
- Response or dependent variables are the variables that are of interest in an experiment and are measured or observed.
- Predictor, explanatory, or independent variables are any additional factors in the experiment that may be controlled or assessed by the researcher and have an impact on the answer.
What is a predictor variable example?
In personnel selection, for example, predictors such as qualifications, relevant work experience, and job-specific abilities (e.g., computer competence, ability to speak a certain language) may be used to estimate an applicant's future job performance.
Is a predictor variable dependent or independent?
- The risk factors and confounders are referred to as the predictors, or explanatory or independent variables, whereas the outcome variable is also known as the response or dependent variable.
- The independent variables are designated by "X" while the dependent variable is denoted by "Y" in regression analysis.
