Answer:
0.0537
Step-by-step explanation:
This follows a binomial distribution with : n
Number of trials 'N' = 12 ; Probability of success (difference between speakers) 'p' = 1/2 or 0.5 ; Probability of failure (no difference b/w speakers) = 1/2 or 0.5 ; No of success 'r' = 3
P (X = 3) = 
= 12C3 (0.5)^3 (0.5)^9
0.0537

General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define Expression</u>
4t - 18 - t + 2t + 20
<u>Step 2: Simplify</u>
- Combine like terms (t): 5t - 18 + 20
- Combine like terms (Z): 5t + 2
Answer:
they need 4 buses
60+60+60=180 that does not get you to 196 so you would add 1 more bus
which equals 4 buses

Answer:
A
Step-by-step explanation:
We only need to calculate one of the functions shown. I will be using |x| - 1 because it is the simplist.
|x| makes a V shape and we know it only goes from -1 to 1. And that means it can be A or D. Next we apply the -1 so that it will go down. The only option that fits this is option A.
