Aiden is saving money to buy a new computer. He made a scatter plot and linear model for the amount of money he has saved over the past eight weeks . The equation of the line y=17.63 + 27.52 . Use the model to predict how much Aidan saved after 5 weeks . A. $88.15 B.$50.15 C.$115.67 D.$32.52

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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
