A community is hit by a famine. So the government decides to give each member in a household a potato. There are exactly 10 households with members as follows; 2,3,6,7,8,9,4,13,15,5. The potatoes are served in packages where by each package cointains 5 potatoes. Find out the number of packages needed to feed the community.

what are the statments

step-by-step explanation:

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

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
