Compare and contrast measures of central tendency and measures of variability.

Mathematics

Answer:

While central tendency tells you where most of your data points lie, variability summarizes how far apart your points from each other. Data sets can have the same central tendency but different levels of variability or vice versa. Together, they give you a complete picture of your data.

What is the equation of the line that is perpendicular to y=2/3x-5 and passes through (6,-1)?
riadik2000 [5.3K]

Answer: 2y + 3x - 16 = 0

Step-by-step explanation:

Equation of the line  is    y = 2x/3 - 5

From the equation , the slope m₁ = 2/3. therefore recall, from condition for perpendicularity, m₁m₂ = -1

The product of their gradient must be (-1).

Now since m₁ = 2/3 and m₁m₂ =-1

                          2m₂/3 = -1

Therefore , m₂ = -3/2.

Since the equation passes through the coordinate of (6,-1)

we now substitute for x and y in the equation of a line to get the y intercept (c)

  y = mx + c

  -1 = -3x/2 +c

  -1 = -3/2 x 6 + c

  -1 = -9 + c

  -1 + 9 = c

 Therefore c = 8

Now to get the equation of line that is perpendicular to y = 2x/3 - 5

 y = -3x/2 + 8

making it a linear equation,

 2y = -3x + 16

 2y +3x - 16 = 0

Answer:

The answer is "Option a".

Step-by-step explanation:

please find the attached file.

In the given question, the positive correlation shows the scatterplot and, by adding six now higher calories, low-fat pasta, is the positive value for the new correlation of the coefficient will be decreasing.

In this question, the points are more close to the line and increasing from left to right, which can be mostly like, that's why the choice "a" is correct.
