Acereal company puts toys into 40% of its cereal
boxes. lydia wants to know what the probability is
of getting 2 toys if she buys 7 boxes of cereal. how
could she simulate her question using a random
number table?
a. look at the first 2 digits in the table. let digits
from 0 to 7 represent getting a toy, and other
digits represent not getting a toy.
b. look at the first 7 digits in the table. let digits
from 1 to 3 represent getting a toy, and other
digits represent not getting a toy.
c. look at the first 7 digits in the table. let digits
from 0 to 3 represent getting a toy, and other
digits represent not getting a toy.
d. look at the first 2 digits in the table. let digits
from 1 to 7 represent getting a toy, and other
digits represent not getting a toy.

I'd say D

Step-by-step explanation:

Because it makes the most sense and it is the most notable one.

Correct me if I'm wrong.

Hope this helps :).

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
