A machine is used to fill bags with a popular brand of trail mix.
lorasvet [3.4K]

The least weight of a bag in the top 5 percent of the distribution is; 246

From the complete question below, we are given;

Population mean; μ = 240

Population standard deviation; σ = 3

Z-score formula is;

z = (x' - μ)/σ

  • Now, we want to find the least weight in the top 5 of the distribution and as such we will use;

1 - 0.05/2 = 0.025 as significance level

Z-score at significance level of 0.025 is 1.96

Thus;

1.96 = (x' - 240)/3

3 × 1.96 = x' - 240

x' = 240 + 5.88

x' = 245.88

Approximating to a whole number gives;

x' = 246

Complete question is;

A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal, with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?

A cylindrical tank with radius 5 m is being filled with water at a rate of 3 m3 ymin. How fast is the height of the water increa
Marizza181 [45]

The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.

<h3>How to calculate the volume of a cylinder?</h3>

Mathematically, the volume of a cylindrical tank can be calculated by using this formula:

V = πr²h

Where:

  • h is the height.
  • r is the radius.

Differentiating with respect to h, we have:

dV/dt = πr²(dh/dt)

3 = 3.142 × 5² × dh/dt

3 = 78.55dh/dt

dh/dt = 78.55/3

dh/dt = 26.18 m/mn.

How many moles of silver atoms are there in 1. 8 x 1020 atoms of silver?.
Lilit [14]

Answer:

Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.

First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.

Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.

Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?

amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms

amount of moles of silver= 2.98×10⁻⁴ moles

Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
