Using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.

According to the question,

It takes 5.24 cubic centimeters of molten steel to make ball bearings that each have a diameter of 1 centimeter.

Radius = 1/2 = 0.5 cm

volume V of one ball bearing is: V=(4/3)*π*r³

= 4/3 * π * (0.5)³

=0.524 cm³

In order to find number of ball bearings out of molten steel only if we divide the volume of steel by the volume of the ball bearing

5.24/0.524=10.

Hence, using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.

For f(x)=3x+1 and g(x)=x^2-6, find (f-g)(x)
Westkost [7]

Answer:

(f - g)(x) = (3x + 1) - (x^2 - 6) = 3x + 1 - x^2 + 6 = -x^2 + 3x + 7

pentagon [3]

Using the Central Limit Theorem, the standard error for the distribution of 559 restaurants is given by:

s = 0.0398.

<h3>What does the Central Limit Theorem state?</h3>


The Central Limit Theorem states that for a population with standard deviation \sigma and sample size n, the standard error is given by:

s = \frac{\sigma}{\sqrt{n}}

For this problem, the parameters are given as follows:

\sigma = 2.94, n = 559

Hence:

s = 2.94/sqrt(559) = 0.0398.

The standard error for the distribution of 559 restaurants is given by:

s = 0.0398.
