The value of the probability P(A and B) is 0.12
<h3>How to determine the probability?</h3>
The given parameters are
P(A) = 0.40
P(B) = 0.30
Given that the events are independent events;, we have:
P(A and B) = P(A) * P(B)
So, we have:
P(A and B) = 0.40 * 0.30
Evaluate
P(A and B) = 0.12
Hence, the value of the probability P(A and B) is 0.12

Answer:
x ≈ {-1.8, 0.5}
Step-by-step explanation:
I find a graphing calculator to be about the easiest way to solve these. It is convenient to put the equation into the form f(x) = 0. Here we can do that by subtracting 3x^2 from both sides.
9x^2 +8x -5 = 3x^2 . . . . . given
6x^2 +8x -5 = 0 . . . . . . . . subtract 3x^2
The solutions to this are the x-intercepts of the graph:
x = -1.8 or +0.5

Answer:
100 beats per minute
Step-by-step explanation:
If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.
To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:
28.8 secs = 48 beats
60 secs = x beats
Cross multiply
28.8*x = 60*48
28.8x = 2,880
Divide both sides by 28.8
x = 2,880/28.8
x = 100
✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM
