Answer:
48
Step-by-step explanation:
f(x) = x³
f'(x) = 3x²
f'(-4) = 3(-4)²
f'(-4) = 48

Answer:
The P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results ( A )
Step-by-step explanation:
The False statement about using the confidence interval method when testing a claim about μ when σ is unknown is ; The P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results
This is because sometimes the values gotten from the p-value and confidence interval differs and this occurs mostly when the sample size is very small.
Answer:
The correct option D
Step-by-step explanation:
Linear Programming deals with the optimization (maximum or minimum) of a function of variables, known as objective function, subject to a set of linear equations and/or inequalities known as constraints.
Graphical Method can be used only for Linear Programming Problem with only two variables. The graphical method provides a pictorial representation of the solution process and a great deal of insight into the basic concepts used in solving large Linear Programming Problems.
Answer:
a. y(cost) = 4.95g + 5.45c
b. $91.12
Step-by-step explanation:
a. Joe bought g gallons of gasoline for 4.95, this can be represented as 4.95g. He bought c cans of oil for 5.45, this can be represented as 5.45c. Add them together to find the total cost, and it will look like this: y(cost) = 4.95g + 5.45c.
b. g = 9.6 gallons
c = 8 cans of oil
Plug these into the equation we did in part A
y(cost) = 4.95(9.6) + 5.45(8)
Solve
y(cost) = 47.52 + 43.6
y(cost) = 91.12
Therefore, if Joe bought 9.6 gallons of gasoline and 8 cans of oil, all in all he spent $91.12.
