On any given test, there is a 41% chance that a student will get a B or better. A teacher randomly selects tests until there is a B or better. Assume the selections are independent. What is the probability that it will take exactly 4 selections to get a B or better? What is the probability that it will take more than 3 selections to get a B or better?
Explanation:
Probability of exactly 4 selections
= (100% - 41%)³(41%) = 8.42%.
Probabiluty of more than 3 selections
= (100% - 41%)³ = 20.54%.

The vapor pressure of ethanol is 54.68 mm Hg at 25°C.
How many grams of chlorophyll, C55H72MgN4O5, a nonvolatile, nonelectrolyte (MW = 893.5 g/mol), must be added to
174.9 grams of ethanol to reduce the vapor pressure to 53.25 mm Hg ?
ethanol = CH3CH2OH = 46.07 g/mol.
___g chlorophyll?
Answer:
88.19 g
Explanation:
From Raoult's law;
P° - P/P° = XB
XB = mole fraction of solute = number of moles of solute(n)/number of moles of solute(n) + number of moles of solvent (N)
But N>>n
So,
XB = number of moles of solute/number of moles of solvent
Number of moles of solute = mass of solute (WB)/molar mass of solute (MB)
number of moles of solvent = mass of solvent (WA)/molar mass of solvent (MA)
Hence;
P° - P/P° = WB/MB * MA/WA
WB = (P° - P/P°) (MB * WA/MA)
Substituting values;
WB = (54.68 - 53.25/54.68) * (893.5 * 174.9/46.07)
WB = 88.19 g

Explanation:
A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.
Answer:
Answer: 4,772.8 cm2
Explanation:
The company will need 3,583.2 square inches of paper to make 15 labels.
What is cylinder?Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.
The formula for circumference is:
Circumference = π × diameter
Circumference = 3.14 × 8in
Circumference = 25.12in
So the label will need to be 25.12 inches long.
The height of the label will be the same as the height of the can, which is 9 inches.
To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:
Total area = length × height × number of labels
Total area = 25.12in × 9in × 15
Total area = 3,583.2 square inches
Thus, the answer is 3,583.2 square inches.

tipping over dominoes
The tipping over dominoes game most represents a wave. Thus, option D is correct.
What is a wave?An alteration or disruption that causes energy to be transferred gradually from one point to another in a medium; it may involve an elastic deformation or a change.
The game Tipping Over Dominoes most likely represents a wave. This game involves lining up the dominoes in sequence and pushes the starter. This will cause a delightful cascade of dominoes to fall across the push-up site to the final domino.
Every domino goes down with the wave's direction in mind. The wave of sound is a better physical illustration. The changes in the position of the dominoes as they fall have both horizontal as well as vertical elements.
Therefore, option D is correct.

Which of the following is produced when sugar is processed in an animal cell
Answer:
Carbon dioxide
Explanation:
Glycolysis which is the breakdown of sugar in living things, is a metabolic process that helps to release energy. Pyruvate is a product of this process that involves ten steps. After glycolysis has occurred, pyruvate is moved to the cellular powerhouse (the mitochondria) in the presence of oxygen.
There, carbon dioxide is extracted from pyruvate and acetyl coenzyme A is generated. This shows that carbon dioxide is produced when sugar is processed in animal cells.
