Suppose you roll not die. Find the Probability of not rolling an even number

irina [24]

I think you mean roll a die. To do this you would find the number of non-even numbers and divide that number by the total amount of numbers on the die. On a normal six-sided die these numbers would be 1,3,and 5, so your probability of not rolling an even number would be 50%

The absolute value function, f(x) = |x + 2|, is shown.

Georgia [21]

ANSWER

all real numbers

EXPLANATION

The given absolute value function is

$f(x) = |x + 2|$

This function is obtained by shifting the graph of

$y = |x|$

to the left by 2 units.

Since the domain of the parent function is all real numbers, the domain of the transformed function is also all real numbers because the shifting the parent function horizontally or vertically does not affect the domain.

Describe this number line and the numbers and fractions shown.

Mariana [72]

Answer:

The number line goes from negative two to two.

The numbers shown by the number line (-2, -1, 0, 1 and 2) are all integers.

Between each pair of numbers, there are 4 equal segments, each one of 1/4 = 0.25 units length. Therefore we can locate, for example, 1.25, 0.5 and -0.75 at the number line.
