Maggie’s bank has assigned her a temporary 3-digit pin to use with her atm card. each digit is a number from 1 to 5, inclusive, and no digit can be used more than once in the pin. which multiplication problem can be used to determine the probability that the pin she was assigned was 123?

a 1/5 1/5 1/5
b 1/5 1/4 1/3
c 4/5 3/4 2/3
d 4/5 4/5 4/5

B 1/5 1/4 1/3

Step-by-step explanation:

The first digit Maggie's bank picked from the 5 digit available, so 1/5.

The second digit will be picked from the 4 remaining digits available, so 1/4.

For the final digit, the bank will have only 3 options to choose from, so 1/3.

So the possibility for the 3-digit assigned PIN to be 123 is

1/60, so the formula is the one presented in the B option: 1/5 1/4 1/3

The answer on edgenutiy is B

Step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
