4 0

Answer:

Step-by-step explanation:

10x - 15y = 21

15y = 10x - 21

y = ⅔x - 7/5

slope of line is ⅔

slope of any perpendicular to line is -3/2

y = kx + k

slope of line is k

k = -3/2

PLSSSS HELP!!!! Math isn't my specialty
ANTONII [103]

Answer:

Minimum value = 2

Maximum value = 26

Lower quartile = 4

Median = 14

Upper quartile = 20.5

Step-by-step explanation:

Five number summary:

  • Minimum value
  • Maximum value
  • Lower quartile
  • Median
  • Upper quartile

Assuming the stem is the tens column and the leaves are units, the data values are:

2, 2, 3, 5, 7, <u>13, 15</u>, 16, 20, 21, 24, 26

Minimum value = 2

Maximum value = 26

<u>Median</u> - middle value

As there is an even number of data values, the median is the mean of the 6th and 7th data values.

Median = (13 + 15) ÷ 2 = 14

<u>Lower quartile</u>

As there is an even number of data values, the lower quartile is the mean of the 3rd and 4th data values.

Lower quartile = (3 + 5) ÷ 2 = 4

<u>Upper quartile</u>

As there is an even number of data values, the upper quartile is the mean of the 20th and 21st data values.

Lower quartile = (20 + 21) ÷ 2 = 20.5
