Answer:
5 + 2q = 15
Step-by-step explanation:
The perimeter is 4 + 2 + q + (q - 1) = 15.
Add 4 + 2 then subtract the sum from both sides.
q + (q - 1) = 9
This can be simplified further by adding the "q" variables together.
2q - 1 = 9
Add 1 to both sides.
2q = 10
Divide both sides by 2 to isolate q.
q = 5

Answer:
The probability that a randomly selected adult is either overweight or obese is 0,688
Step-by-step explanation:
Probability that an american adult is overweight = 0,331
Probability that an american adult is obese = 0,357
Let's find the probability that an adult is either overweight or obese, that means both events are mutually exclusive. We are interested in the probability that just one event occurs, that probability is the sum of their individual probabilities
P(overweight ∪ obese) = P(overweight) + P(obese) = 0,331 + 0,357 = 0,688
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)]
