Answer:p(x)=(x-1)(x-3)²

Step-by-step explanation:

The polynomial p(x)=(x-1)(x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1.

When testing for differences between treatment means, a confidence interval is computed with __________________?

KIM [24]

The confidence interval is based on mean square error. The mean squared error (MSE) of an estimator measures the average of the squares of the errors or deviations. MSE is calculated by the formula attached in the picture, where Xbar is a vector of predictions, X is the vector of predicted values.

Can someone help me with this question pls?

Novosadov [1.4K]

Answer:

$x^{2} - 25$

Step-by-step explanation:

Area is side x side, so naturally it would be: (x+5)(x - 5)... Though to simplify, those parenthesis can be FOILed. (Reminder: "FOIL" means First - Outer - Inner - Last)

$x^{2} - 5x + 5 x - 25$
