Shelley has been throwing pairs of socks at her laundry basket across the room. in 21 throws, 13 times the socks have landed in the basket. on her next throw, (assuming her past accuracy holds consistent) what is the probability (written as a percent) that shelley will get the pair of socks into the basket? round your answer to the nearest tenth of a percent.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
