Answer:
0.6
Step-by-step explanation:
Given the regression equation :
y = 0.2x + 3,
The actual value of y when x = 5 is 4.6
The predicted of y using the model when x = 5 is :
Put x = 5 in the equation :
y = 0.2(5) + 3
y = 1 + 3
y = 4
The error in the value of y predicted is :
Error = Actual value - Predicted value
Error = 4.6 - 4
Error = 0.6
Answer:
Total cost = 16
Step-by-step explanation:
In the equation of cost, we can see that each rose costs 3 and each petunia costs 2.5.
To find the total cost of two roses and four petunias, we can use the values r = 2 and p = 4 in the equation given, so:
Total cost = 3r + 2.5p = 3*2 + 2.5*4 = 6 + 10 = 16
So the total cost of two roses and four petunias is 16.
