14 because if 1 case held 3 boxes and 3 boxes held 3 Binders, that means u would have to divide 3 by 126 which equals 42 and u would have to divide that by 3 which equals 14.

<h2>Ratio of area of the square to the area of the circle = π/4</h2>

Step-by-step explanation:

Let the side of square be a and radius of circle be r.

The perimeter of a particular square and the circumference of a particular circle are equal.

Perimeter of square = 4 x a = 4a

Circumference of circle = 2πr

Given that

4a = 2πr

$a=\frac{\pi r}{2}$

We need to find the ratio of the area of the square to the area of the circle.

Area of the square = a²

Area of the circle = πr²

$\texttt{Ratio of area of the square to the area of the circle =}\frac{a^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle =}\frac{\left ( \frac{\pi r}{2}\right )^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle = }\frac{\pi}{4}$

Ratio of area of the square to the area of the circle = π/4

Each month, an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard d

Annette [7]

a) For x = 27:

z = 27-28/2 = -0.5

For x = 31:

z = 31-38/2 = 1.5

From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%

b) For x > 30.2:

z = 30.2-28/2 = 1.1

From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%

PLZ HELP ASAP I don’t know the answer and I keep getting it wrong

Nuetrik [128]

I believe the Slope- intercept formula is y = mx + b

Slope is your m = -4
Point: (2, -4)
x = 2
b is your y-intercept = -4

Answer: y = -4(2)+ -4 or -4(2)-4?

So sorry if it’s wrong but I hope this helps
