The answer is A because a sample of 500 boys and girls from middle schools across the state represents the population.
Answer:
The circumference is 59.66 cm
Step-by-step explanation:
we know that
The circumference of a circle (ring) is given by the formula

If the radius is

substitute in the formula

----> exact value
assume

substitute

We can apply Quadratic equations in real-world like; sports, bridges, projectile motion, shapes of bananas etc.
Following are three pictures of real world application of quadratics.
Example 1:- Here we can see a Cyclist follows a quadratic path to jump over the obstacles.
Example 2:- Here we see a man throwing a basketball towards the net following a slightly upward direction that goes through a quadratic path.
Example 3:- Here a football player kicks the ball in the sky and it goes through a quadratic path to cover some distance.
Ok so our two variables will be:
x=age y=price
Our equation is:
y= -3000x + $25,635
