Li designed a survey to determine how comfortable students at her middle school are with fractions. There are 600 students in her middle school. The students are equally distributed among grade levels. She selected a sample of 28 students in her first-period class. Which best explains Li’s sample?

[ad_1]

The correct answer to this is:

Nonrandom and biased

 

The method of Li’s sampling has a
tendency that some elements or portion in the population has no chance of
selection. Further, it was not stated which portion of the population she
obtained the sample thus we cannot accurately determine the probability of
selection. This kind of sampling results in a bias. A biased sampling is a type
of nonrandom sampling.

[ad_1]

Answered by answersmine AT 22/10/2019 – 04:56 AM

Antidepressant drugs have been designed to increase levels of serotonin and norepinephrine. Serotonin is a hormone that is responsible for the regulation of our mood , anxiety and happiness. Norepinephrine is also a hormone that is secreted as a response to stress. It is deemed to be similar with the hormone adrenaline. Low levels of these hormones are associated with depression. Antidepressant drugs works in increasing the levels of these hormones to cure or treat depression. However, these drugs do not necessarily cure depression, they are only effective at improving the mood and relieving some of the symptoms along with it.

Karl Marx developed the economic theory of communism.

Further Explanation:

One of Karl Marx’s most famous contributions came in his book the Communist Manifesto. This book explained Mark’s views on government, the economy, and ultimately lead to the creation of communism as an idea.

A communism system is one that is economic and political in nature. In this system, the government would control the means of production, the distribution of goods and resources, and would overall have significant control over society. This system of communism is the opposite of the capitalist/democratic system used in America today. These two ideologies would clash during the mid 20th century in what is now known as the Cold War.

Marx’s ideas were based on his observations of the world around him. He felt that the mistreatment of labor by industry and private corporations would ultimately lead to an uprising by angry laborers all over the world.

Charlie had a waist circumference of 47 inches and a BMI of 29 this shows that she is overweight. BMI test level is high from normal ranges shows that she is at higher risk of disease. She should lose weight and concern to the doctor.

Further Explanation:

Body mass index (BMI) is a measured value derived from the height of a person and mass.

{text{BMI}}=dfrac{{{text{mass (kg)}}}}{{{{left( {{text{height}}}right)}^2}{{left({text{m}}right)}^2}}}

BMI indicates whether the person is healthy or overweight mainly used by physicians.

• Range of BMI in a normal person is 18.5-25mathbf{kg/m}^{2}

• Range of BMI in skinfold person is 25-30mathbf{kg/m}^{2}

• Range of BMI in underweight person is 15-18.5mathbf{kg/m}^{2}

The skinfold measurement test is used to determine a person’s body fat percentage and body composition.

In this test, we are the proportion of body fat by determining skinfold thickness at pinches specific part of the body. The estimate of these folds is determined the fat beneath the skin, also called subcutaneous adipose tissue.  

The tester pinches the skin at the site and drags the fold of skin away from the muscle so only the fat tissue and skin are being held. The skinfold thickness is measured by skinfold calipers in millimeters.

Skin test includes the seven locations of the body:

1. Triceps

2. Quadriceps

3. Suprailiac

4. Pectoral

5. Subscapular

6. Midaxilla

To be bold and brave and happy as can be,
To trek and travel and sail the seven seas.

You have designed a rocket to be used to sample the local atmosphere for pollution. It is fired vertically with a constant upward acceleration of 17 m/s2. After 30 s, the engine shuts off and the rocket continues rising (in freefall) for a while. (Neglect any effects due to air resistance.) The rocket eventually stops rising and then falls back to the ground. You want to get a sample of air that is 23 km above the ground.

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

The Mughal–Persian Wars were a series of wars fought in the 17th and 18th centuries between the Safavids and Afsharid Empires of Persia, and the Mughal Empire, over what is now Afghanistan. The Mughals consolidated their control of what is today India and Pakistan in the 16th century, and gradually came into conflict with the powerful Safavids and Afsharids, led by Ismail I and Nader Shah respectively. Aside from Nader Shah’s invasion of the Mughal Empire, most of the conflict between the two powers were limited to battles for control over Kandahar.[1]

The Mughal–Safavid War of 1622–23 was fought over the important fortress city of Kandahar, in Afghanistan, between the Safavid empire of Persia and the Mughal empire of India. It resulted in a clear Persian victory.

Muhammad Ali Beg was the Persianambassador sent to the Mughal court of Jahangir by Abbas I of Persia, arriving in time for Muharram in March 1631. He remained there until October 1632, thus negotiating an end to the conflict between the Mughals and the Safavids.

Having secured crushing victories against the Ottomans, Shah Abbas desired to capture the strategic fortress on Kandahar since he had lost it in 1595.[2] In 1605 the governor of Herat, Hosayn Khan, besieged the city but the tenacious defense of the Mughal governor, Shah Beg Khan, and the arrival in the next year of a relieving Mughal army to Kandahar forced the Safavids to retreat.[3][4] With the conclusion of the Ottoman-Safavid War (1603-1618), Shah Abbas was secure enough for a war on his eastern frontier,[2] so in 1621 he ordered an army to gather at Nishapur.[2] After celebrating the new year at Tabas Gilaki in southern Khorasan, Abbas joined with his army and marched on Kandahar where he arrived on 20 May and immediately began the siege.[2] Though Jahangir had information of the Persian’s movements he was too slow to respond,[2] and without reinforcements the small garrison of 3,000 men could not hold for long against the superior Persian army.[5]

The Emperor asked his son and heir apparent Khurram who was at Mandu in the Deccan to lead the campaign, but Khurram evaded the assignment fearing to lose his political power while he was away from court.[6] The relief force the Mughal’s could assembled proved too small to raise the siege,[4] so after a 45-day siege the city fell on 22 June followed shortly after by Zamindawar.[7] After fortifying the city and appointing Ganj Ali Khan as governor of the city,[3] Abbas returned to Khorasan via Ghur, subduing on the way troubling emirs in Chaghcharan and Gharjistan.[8] The rebellion of Khurram absorbed the Mughal’s attention, so in the spring of 1623 a Mughal envoy arrived at the Shah’s camp with a letter from the Emperor accepting the loss of Kandahar and putting an end to the conflict.[9]

i would just make this into an equation!!
t for the number of turkey sandwiches
s for the number of steak sandwiches

it’s 4 dollars for every turkey sandwich and 6 for every steak sandwich, so:
4t + 6t = 4524
you can call this your “profit” equation. it just tells you how much money they made. however many sandwiches they sold at those rates gave them the outcome of 4524

then you need a second equation, to account for the number of sandwiches, and instead of worrying about profit you need to focus on the number of sandwiches sold (which is why they gave you the number 925)
t + s = 925

the number of turkey sandwiches plus the number of steak sandwiches adds up to a total of 925 sandwiches.

so you have two equations:
4t + 6s = 4524
t + s = 925

to figure out the number of turkey sandwiches sold, you want to solve for the variable t. this can be done a few ways with your two equations, but the easiest to follow will probably be substitution in this case.

first, isolate your variable t in one of the equations. it’ll be easier with the second one.
t = 925 – s

then you plug that into your first equation:

4(925 – s) + 6s = 4524
then solve it like normal.

4(925 – s) + 6s = 4524
3700 – 4s + 6s = 4524
3700 + 2s = 4524
2s = 824
s = 412

so now you know your s variable. plug that back into the following equation, and you have the number of turkey sandwiches sold:
t = 925 – s
t = 925 – (412)
t = 513

513 turkey sandwiches were sold
