Answer:
C. -24
Step-by-step explanation:
Plug in values into the given equation
Answer:
a. There is a causation relationship and positive trend between number of hours on homework and higher test scores.
b. 76
Step-by-step explanation:
a. Since the dots all follow a linear progression and increase closely together this is a positive trend and likely a causation relationship.
b. y=7x+41 can predict a test score. x is the number of hours, so if 5 if the number of hours then y=7(5)+41 = 35+41=76
D. 75 cm
Step-by-step explanation:
fill in the y with 20.5, so you get 20.5=0.3x-2. Add the 2 to the 20.5 so you get 22.5=0.3x. Divide both by 0.3 to get 75=x.
sorry if it's a bd explanation, hope this helps :)
I hope this is just a maths problem coz if this is your card number I wouldn't be putting it on here for all to see.
