As a part of a contest, a computer picks a digit from 0 to 7, inclusive, 3 times. if the 3 digits are all the same, the contesta

EastWind [94]

There are 8 numbers for the computer to choose from.
So the probability of choosing a particular number is 1/8.
The first number can be any one of the 8.
The second and the third must be the same as the first, with probability 1/8.

Therefore the probability that all three numbers are the same
= (1/8)(1/8) = 1/64 [ player will win a prize ]
(=0.03125)

The isosceles triangle is a scale drawing of a flag.

Zolol [24]

Answer:

Scale factor = $\frac{1}{2}$

Step-by-step explanation:

Perimeter of the actual flag = 22 in.

Perimeter of the scale drawing of the flag = 11 in.

Since, perimeter of a triangle = Sum of all three sides of the given triangle

Therefore, scale factor of the drawing

= $\frac{\text{Measure of the side of drawing}}{\text{Measure of the side of actual}}$ = $\frac{\text{Perimeter of drawing}}{\text{Perimeter of actual}}$

= $\frac{11}{22}$

= $\frac{1}{2}$

Therefore, scale factor of the drawing will be $\frac{1}{2}$ .

Each side of the scaled triangle will be half of the actual triangle.

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.
