Harold measures the heights in inches of the new plants that are growing in his greenhouse. He records the lengths shown below and wants to plot them on a line plot.

19.5 21.5 18.0 19.5 19.25 19.5 21.0
18.25 20.5 18.75 19.0 19.0 19.25 22.0
Use the drop-down menus to complete the following sentences about the line plot.

The line plot has [Choose..] dots plotted on it. The least value plotted on the line plot is [Choose..] The greatest value plotted on the line plot is [Choose..] The height of [Choose..] inches occurs the most often.

(PLEASE this one is the hardest of them all.. sense i know people scam me by putting the a answer even if its wrong just to get the POINTS.. so now if its right ill give 10 points..)

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

answer:   2 multiplied by x =24

step-by-step explanation:

the value of x is 9 ⇒ answer b

step-by-step explanation:

* we can solve this problem using cosine and sine rule

- in δ abc

∵ ab = 36 , bc = 28 , ac = 16

- lets find the measure of angle b using the cosine rule

∵ cos b = [ab² + bc² - ac²]/2(ab)(bc)

∴ cos b = [36² + 28² - 16²]/2(36)(28)

∴ cos b = 19/21

∴ m∠b = cos^-1(19/21) ≅ 25°

- lets find the measure of angle a using the sine rule

∵ sina/bc = sinb/ac = sinc/ab

∴ sina/28 = sin25°/16 ⇒ by using cross multiplication

∴ sina = 28 × sin25°/16

∴ sina = 0.7396

∴ m∠a = sin^-1(0.7396) ≅ 48°

- from the figure m∠abd = m∠dbc

∵ m∠abc = 25°

∴ m∠abd = 25°/2 = 12.5°

- in δabd

∵ m∠a = 48° , m∠abd = 12.5°

∵ the sum of the measures of the interior angles of any δ is 180°

∴ m∠adb = 180° - (48° + 12.5°) = 119.5°

∵ ab = 36

∵ ad = x

- use the sine rule to find x

∵ sin∠adb/ab = sin∠abd/x

∴ sin119.5°/36 = sin12.5°/x ⇒ by using cross multiplication

∴ x = 36 × sin12.5°/sin119.5° = 8.95 ≅ 9

* the value of x is 9
