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
The area of a parallelogram is equal to the base multiplied by the height. So in this instance it would be (3x+5)*(7x-1). Foil out the binomials. 21x^2+35x-3x-5 Combine like terms. 21x^2+32x-5
The area is 21x^2+32x-5
Answer and explanation:
V originally equals u + at, but when you plug in u, a, and t you get a number answer.
u = 2
a = 15
t = 1/5
Rewrite the expression with the numbers plugged in.
V = (2) + (15)(1/5) <em>Multiply 15 by 1/5</em>
V = 2 + 3 <em>Add 2 and 3 together</em>
V = 5
<h2><u>So V would equal 5</u></h2>
