Explanation:

If we could tell the repeated letters apart, then there would be

11*10*9*8*7*6*5*4*3*2*1 = 39,916,800

different ways to scramble up the letters.

However, we have 2 copies of b and 2 copies of i

So we have to divide by 2*2 = 4 to correct this overcounting

(39,916,800)/4 = **9,979,200**

**Step-by-step explanation:**

-9g = -8g + 8

- 9g + 8g = 8

-1g = 8

g = 8 ÷ -1

g = -8

**Answer:**

Company X - 190 students

Company Y - 114 students

No phones - 76 students

**Step-by-step explanation:**

1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population

380/120 = 3.16666667 or 3 & 1/6

**380 **comes from the **total population of students **and **120 **comes from the **randomly selected. **

2) Use our multiplier to compare the results to the population

<u>People with Company X</u>

<u>People with Company Y </u>

<u>People with no cell phone</u>

- 24 * 3.166667 = 76.0000000001 = 76 (rounded)

<u>**Double check**</u>

190 + 114 + 76 = 380
