Answer:

mean = 7

median = 7

range = 9

mid range = 7.5

Step-by-step explanation:

3, 5, 6, 7, 7, 9, 12

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

12 - 3 = 9  

Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order

3, 5, 6, 7, 7, 9, 12

median = 7

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

(6 + 12 + 5 + 7+  7 + 3 + 9) / 7 = 7

Mid range = (highest value + lowest value) / 2

(12 + 3) / 2 = 7.5

Tell whether the lines for each pair of questions are parallel or perpendicular or neither y=5/3x+3. 20x+12y=12
disa [49]

neither

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = \frac{5}{3} x + 3 is in this form

with slope m = \frac{5}{3}

rearrange 20x + 12y = 12 into this form

subtract 20x from both sides

12y = - 20x + 12 ( divide all terms by 12 )

y = - \frac{5}{3} + 1 ← in slope-intercept form

with slope m = - \frac{5}{3}

Neither of the conditions for parallel/ perpendicular slopes are met

Hence the lines are neither parallel/ perpendicular
