I percieve this as a trick question. The probability is 100% because if the 3 randomly selected students pertain to the group of students who like statistics better than algebra, then obviously, they are all going to say they like stats better than algerbra.
Answer:
-3x+6
Step-by-step explanation:
-2x - 1 - x + 7
collect like terms and calculate:
-3x+6
The solution for r in the given equation is r = √[(3x)/(pi h)(m)]
<h3>How to determine the solution of r in the equation?</h3>
The equation is given as:
m = (3x)/(pi r^(2)h)
Multiply both sides of the equation by (pi r^2h)
So, we have:
(pi r^(2)h) * m = (3x)/(pi r^(2)h) * (pi r^(2)h)
Evaluate the product in the above equation
So, we have:
(pi r^(2)h) * m = (3x)
Divide both sides of the equation by (pi h)(m)
So, we have:
(pi r^(2)h) * m/(pi h)(m) = (3x)/(pi h)(m)
Evaluate the quotient in the above equation
So, we have:
r^(2) = (3x)/(pi h)(m)
Take the square root of both sides in the above equation
So, we have:
√r^(2) = √[(3x)/(pi h)(m)]
Evaluate the square root of both sides in the above equation
So, we have:
r = √[(3x)/(pi h)(m)]
Hence, the solution for r in the given equation is r = √[(3x)/(pi h)(m)]

Answer:
The required probability is 
or 0.125
Step-by-step explanation:
Consider the provided information.
The spinner is spin twice and we want the sum should be 5.
We can get 5 if first spin gives us 2 and second spin gives 3.
Or we can get 5 if first spin gives us 3 and second spin gives 2.
There are 8 section out off which Three sections numbered 1, one section numbered 2, and four sections numbered 3.
The probability of getting 2 is
The probability of getting 3 is 
Now, the probability that the sum of the two spins will be five is:
Hence, the required probability is or 0.125
