How can you check to see if a value of x is a zero of the polynomial
Mila [183]

Answer:

  substitute that value for x in the polynomial and see if it evaluates to zero

Step-by-step explanation:

A "zero" of a polynomial is a value of the polynomial's variable that make the expression become zero when it is evaluated. As an almost trivial example, consider the polynomial x-3. The value x = 3 is a zero because substituting that value for x makes the expression evaluate as zero.

  3 -3 = 0

___

Evaluating polynomials can be done different ways. Straight substitution for the variable is one way. Using synthetic division by x-a (where "a" is the value of interest) is another way. This latter method is completely equivalent to rewriting the polynomial to Horner form for evaluation.

__

In the attachment, Horner Form is shown at the bottom.

The following frequency table summarizes yesterday's orders at Sizzlin' Skillets.
Arlecino [84]

Answer:

the probability that the ext order will be shrimp = 27.78%

Step-by-step explanation:

Vegetable 333

Chicken 666

Pork 222

Beef 222

Shrimp 555

total = 1,998

P (shrimp) = 555 / 1,998 =  0.2777 or 27.78%

in case the numbers in the orders were:

Vegetable 3

Chicken 6

Pork 2

Beef 2

Shrimp 5

total = 18

P (shrimp) = 5 / 18 =  0.2777 or 27.78%

The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.
