Y=mx+b now just re do them
Answer:
1. X = 14
2.X =13
Step-by-step explanation:
The angles are 90 degrees. I did math to check if the x values are correct and they are.
Decrease in the temperature: 5.4×5=27°C
Final temperature: 12-27=-15°C
Answer:
Y = 7.60X + 1246.67
Step-by-step explanation:
Given the data:
Production Volume (units) Total Cost ($)
400 4000
450 5000
550 5400
600 5900
700 6400
750 7000
Using technology, the linear regression calculator, the regression model obtained by fitting the data is :
Y = 7.60X + 1246.67 ; which is the model giving the relationship between Production volume, x and total cost, y.
Slope = 7.60
Intercept = 1246.67
Answer:
15:5 is the ratio of apples to oranges and 5:15 if reverse
