Perpendicular to y=4x-7; contains the point (4,3)

Okay, so a general rule for finding perpendicular lines in the form of y = mx + b is y = (-1/m) + b.
First, let's ignore b (-7) because we're going to find that later.
A perpendicular line to y = 4x + b is y = -1/4x + b.
Alright, so now let's plug in the values. They are in the form of (x,y), so let's plug them in accordingly.

3 = -1/4(4) + b
3 = -1 + b
b = 4
y = -1/4x + 4
So a line perpendicular to y = 4x - 7 is y = -1/4x + 4.

determine the area of a trapezoid the length of the midline of 14 centimeters and the length of the height of 8 centimeters
emmainna [20.7K]

Answer:

Area = 112cm^2

Step-by-step explanation:

Area = (a + b)*h / 2

M = (a + b) / 2

14 = (a + b) /

2*14 = a + b

28 = a + b

Area = 28*8 / 2

Area = 112 cm^2

A boy has 40 red and blue pencils in his pencil case. If the ratio of red to blue pencils is 0.15 to 0.35, how many blue pencils
strojnjashka [21]

Answer:

The boy has 28 blue pencils

Step-by-step explanation:

Given

Total pencils = 40

The ratio of red to blue= 0.15:0.35

We have to find the number of blue pencils

For that we need the sum of ratio = 0.15+0.35 = 0.5

So, the number of blue pencils = (ratio of blue/sum of ratio) * total pencils

=0.35/0.5 * 40

=0.7*40

=28 pencils

Therefore, the boy has 28 blue pencils ..

aksik [14]

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.
