How might having a large percentage of uninsured people negatively affect the entire country

[ad_1]

The uninsured people affects the entire country or more specifically, the insured ones by:

1. Insured people will less likely have a low regular source of care and the benefits befitting those who are insured. several of them are provided with delayed care

2. Insured people will feel unsatisfied of the services they receive because they are not the ones who are focused, instead the uninsured ones.

The insured people are the ones who will suffer a lot compared to uninsured ones.

Read the excerpt from Chapter 5 of Wheels of Change. These traits led commentators to worry that the differences between the sexes were being blurred, a fear that was reinforced as the four newest states—Wyoming, Colorado, Utah, and Idaho—granted women the right to vote in the 1890s. Would the bicycle help bring about a new kind of equality between men and women? Elizabeth Cady Stanton and her colleagues certainly hoped so. At any rate, the image of a female cyclist quickly became associated with efforts to win more rights for women. What conclusion does Macy draw in this synthesis of ideas? Women were granted the right to vote in four states as a direct result of the bicycle’s invention. Female cyclists were quickly becoming associated with efforts to win more rights for women. Stanton and her colleagues hoped women cyclists would join their fight for women’s rights. Wyoming, Colorado, Utah, and Idaho were home to the highest percentage of women cyclists.

[ad_1]

Female cyclists were quickly becoming associated with efforts to win more rights for women.

At the end of the passage, usually where a conclusion is stated, it says that the image of a female cyclist was becoming a symbol for women’s rights. The passage does not tell the reader anything about the percentage of women cyclists. While it does tell the reader about women being granted the right to voted, the connection between that and the bicycle is that it blurs the differences between the sexes. Both men and women were riding bicycles and they were both voting. There is also nothing in the passage about women cyclists as a group joining or not joining the women’s rights movement.

CAN YOU PLEASE HELP ME WITH THIS PROBLEM? This is due by MIDNIGHT 2). Manufacturer A produces hammers that are normally distributed with a mean weight of 4.6 lb and a standard deviation of 0.8 lb. Manufacturer B produces hammers that are normally distributed with a mean weight of 6.3 lb and a standard deviation of 1.4 lb. (a) What percentage of Manufacturer A’s hammers will weigh less than 5 lb? (b) What percentage of Manufacturer B’s hammers will weigh less than 5 lb? (c) Which manufacturer is more likely to produce a hammer weighing exactly 5.2 lb? Explain.

[ad_1]

Part (a)
Manufacturer A;
Mean, μ = 4.6
Std. deviation, σ = 0.8

For the random variable x = 5, the z-score is
z = (x – μ)/σ = (5 – 4.6)/0.8 = 0.5
From standard tables,
P(x<5) = P(z<0.5) = 0.69 = 69%

Answer:  
69% will weigh less than 5 lb.

Part b)
Manufacturer B
μ = 6.3
σ = 1.4

For x = 5, z = (5 – 6.3)/1.4 = -0.9286
From standard tables,
P(x<5) = P(z<-0.9286) = 0.1766 = 17.7%

Answer:
About 18% will weigh less than 5 lb.

Part (c)
x = 5.2 lb

Manufacturer A:
z = (5.2-4.6)/0.8 =  0.75
From tables,
P(x=5.2) = 0.773 = 77.3%

Manufacturer B:
z = (5.2-6.3)/1.4 = -0.7857
P(x=5.2) = 0.216 = 21.6%

Answer:
Manufacturer A is more likely to produce a 5.2 lb hammer because its probability is higher.

A sample of hydrated magnesium sulfate has a mass of 4.052 g. After it is heated, it has a mass of 1.979 g. What is the percentage by mass of water in the hydrate?

[ad_1]

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

=> X solv = 7.33333 / 7.62898 = 0.96125

=> p = 0.96125 * 31.8 torr ≈ 30.57 torr ≈ 30.6 torr.

Answer: 30.6 torr

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

d=sqrt{(c-a)^2+(d-b)^2}.

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

d=sqrt{(x-8)^2+(y-9)^2}.

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

10=sqrt{(x-8)^2+(y-9)^2}.

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

Thymine makes up 28% of the nucleotides in a sample of dna from an organism. approximately what percentage of the nucleotides in this sample will be guanine?

[ad_1]

Answer:

Helicases unwind the two parental DNA’s strands and creates the replication fork; single strand binding proteins keep the single strand from joining.


Further information:

• DNA replication: a biological method occurring in all living organisms that is the basis for biological inheritance

Helicase: It is an enzyme that may unwinds the DNA helix ahead of the replication machinery.

Origin of replication: a specific sequence in a genome at which replication is started.


Steps of DNA replication:

• During initiation, proteins fix to the source of replication while helicase unwinds the DNA helix and two replication forks are formed at the source of replication.

• During elongation, a primer sequence is added with complementary RNA nucleotides, which are then substituted by DNA nucleotides.

• During elongation the leading strand is made constantly, while the lagging strand is made in portions called Okazaki fragments.

• During termination, primers are detached and substituted with new DNA nucleotides and the backbone is stuck down by DNA ligase.

Purpose of DNA replication:

The purpose of DNA replication is to produce two duplicate copies of a DNA molecule. This is essential for cell division during development or repair of damaged tissues. DNA replication ensures that each new cell receives its own replica of the DNA.

Answer details:

Subject: Biology

Level: High school

Keywords:

• DNA replication

• Helicase

• Origin of replication

• Steps of DNA replication

A certain radioisotope has a half-life of 7.32 days. what percentage of an initial sample of this isotope remains after 36 days?

[ad_1]

25) Answer is: less metallic and more nonmetallic.

Electronegativity increases from left to right across a period, atoms have tendency to attract electrons.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

26) Answer is: radioisotope.

Radioisotope has an unstable atomic nucleus and emit energy and particles when it changes to a more stable form.

Francium (Fr) is element with atomic number 87 (87 protons and 87 electrons).

27) Answer is: boils.

Boiling is the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm pressure.

28) Answer is: endothermic.

There are two types of reaction:  

1) endothermic reaction (chemical reaction that absorbs more energy than it releases, ΔH>0).

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).  

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.  

29) Answer is: kinetic.

The average kinetic energy of molecules depends on the temperature.  

As temperature increases, molecules gain more energy from surrounding and move faster.  

Kinetic energy (standard unit is the joule J) depends on speed of the molecule.  

Solid gains kinetic energy to become a liquid and then becomes a gas.

30) Answer is: alpha particles.

This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles.

Rutherford observed the deflection of alpha particles on the photographic film.  

Alpha particles are helium atom particles, consist of two protons and two neutrons.  

According to Rutherford model of the atom: atoms have their charge concentrated in a very small nucleus.  

31) Answer is: highest.

For example, calcium oxide.

Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

32) Answer is: a scientific model.

A scientific model is a representation of an idea, an object, a process or a system that is used to describe and explain phenomena that cannot be experienced directly.

33) Answer is: the superscript is mass number and the subscript is atomic number.

Atomic number(Z) is the number of protons, which is characteristic of a chemical element..

Mass number (A) is the total number of protons and neutrons in a nucleus.

The Contribution Margin per unit (CM) can be calculated
from the difference of Selling Price per unit (SP) and Total Expenses per unit
(TE).

 

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = $1,043,400 / 22,200 units sold

SP = $47

 

Second, calculate all expenses:

Direct materials per unit = $234,948 / 27,970 units
manufactured = $8.4

Direct labor per unit = $131,459 / 27,970 units
manufactured = $4.7

Variable manufacturing overhead per unit = $240,542 / 27,970
units manufactured = $8.6

Variable selling expenses per unit = $113,220 / 22,200
units sold = $5.1

TE = $26.8

 

Therefore the CM is:

CM = SP – TE

CM = $47 – $26.8

CM = $20.2 per unit

Answer:

3 hours.          

Step-by-step explanation:

Let x be the time taken by shoe repairman to repair one pair.

We have been given that his assistant, who takes twice as long to repair a pair of shoes. So time taken by his assistant to repair one pair of shoes would be 2x.

The number of pair of shoes repaired by repairman in one hour would be frac{1}{x}.

The number of pair of shoes repaired by assistant in one hour would be frac{1}{2x}.

We have been given that together they can fix 16 pairs of shoes in an eight-hour day. We can represent this information in an equation as:

frac{1}{x}+frac{1}{2x}=frac{8}{16}

frac{1}{x}+frac{1}{2x}=frac{1}{2}

Let us have a common denominator.

frac{2*1}{2*x}+frac{1}{2x}=frac{1}{2}

frac{2}{2x}+frac{1}{2x}=frac{1}{2}

frac{2+1}{2x}=frac{1}{2}

frac{3}{2x}=frac{1}{2}  

Upon cross multiplying our equation we will get,

2x*1=3*2

2x=3*2

frac{2x}{2}=frac{3*2}{2}

x=3

Therefore, it take 3 hours for the repairman to fix one pair of shoes by himself.
