The numbers of advertisements seen or heard in one week for 30 randomly selected 10) people in the united states are listed below. construct a95y" confidence interval for the true mean number of advertisements. assume that o is 159.5. 598 494 mr 595 728 690 6u 486 735 808 481 298 135 845 764 317 & 9 732 582 677 734 588 590 540 573 727 545 486 702 703.

only 10/60 isn't equivalent

hope this : )

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
