A bottling company produces bottles that hold 10 ounces of liquid.​ Periodically, the company gets complaints that their bottles are not holding enough liquid. To test this​ claim, the bottling company randomly samples 18 bottles and finds the average amount of liquid held by the bottles is 9.7 ounces with a standard deviation of 0.4 ounce. Calculate the appropriate test statistic.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
