Answer:the population is threaded rods produced at the factory that week the sample is the 40 threaded rods selected
Step-by-step explanation:
8 gallons = ? quarts
1 gallon = 4 quarts
Convert:-
4 × 8 = 32
8 gallons = 32 quarts
Trevor used all the quarts besides 1. How many quarts of paint did he use?
32 - 1 = 31
Trevor used 31 quarts of paint.
Answer and Step-by-step explanation:
Polynomial models are an excellent implementation for determining which input element reaction and their direction. These are also the most common models used for the scanning of designed experiments. It defines as:
Z = a0 + a1x1 + a2x2 + a11x12 + a22x22+ a12x1x2 + Є
It is a quadratic (second-order) polynomial model for two variables.
The single x terms are the main effect. The squared terms are quadratic effects. These are used to model curvature in the response surface. The product terms are used to model the interaction between explanatory variables where Є is an unobserved random error.
A polynomial term, quadratic or cubic, turns the linear regression model into a curve. Because x is squared or cubed, but the beta coefficient is a linear model.
In general, we can model the expected value of y as nth order polynomial, the general polynomial model is:
Y = B0 + B1x1 + B2x2 + B3x3 + … +
These models are all linear since the function is linear in terms of the new perimeter. Therefore least-squares analysis, polynomial regression can be addressed entirely using multiple regression
Answer:
b .based on the data, the faster the vehicle travels, the less time it will take to reach the destination.
Answer:
R=19
Step-by-step explanation:
R + 237 = 256
subtract 237 from both sides
R=19
