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.

Kate takes the elevator from the ground floor (which is labeled 0) to a floor three levels below the ground floor. Which number represents the floor where she gets off the elevator?

[ad_1]

Answered by answersmine AT 22/10/2019 – 02:55 AM

The number should be -3. That is because she goes from 0 to three floors bellow, meaning it’s 0-3= -3. The first floor bellow would be -1, the second would be -2, and the third one is -3. It would be different if you counted it as number 1 as they do in some countries, but here it’s -3.

[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.

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

[ad_1]

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

7. Abdomen

Charlie had a waist circumference of 47 inches and a BMI of 29 this shows that she is overweight. Females with waist size 47 inches have higher risk of having disease. 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.

In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the inside of the coat without being absorbed, where the water will absorb the heat instead of themselves, and will cool the through evaporative cooling (heat release through evaporation)

In a deciduous forest, there is much colder temperatures, and significantly less rainfall. These animals would likely want a thicker water-proof coat. This is because the thicker coat would allow heat to become trapped, keeping them warm in the winter, and the water-proof coating prevents water from freezing in their fur, making them colder.

Here are a few pointers; hope this is useful)

Ovation-by definition- is show of appreciation from an audience, for a person’s accomplishments or flaw.

“Everyone deserves a standing ovation because we all overcometh the world.”

A person’s accomplishment could be how they made a positive change in this world, strong leadership- that makes them a effective leader or simply helping others. A person’s flaw- mistakes in life, sin or even guilt should also be considered an appreciation- an ovation for representing mankind’s flaw and that humanity makes mistakes, fulfilling at least one deadly sin such as greed, lust, selfishness etc.

Thus, regardless of a person’s achievement or flaw- a person deserves an applause for, not the least, living in this society and this world that we are all living together and dying together.

That was just the introduction.. the best part is yet to come.. now it’s your turn!!

Here are other pointers to talk about in your essay:

Shakespeare’s famous line “All the World’s a stage. That agrees with your line: “Everybody deserves a standing ovation…”

Shakespeare explains that men and women are like players: they live, and die, some being celebrated and some forever living in solitude till their death. Shakespeare states the world is a “stage” which symbolizes that mankind is in its peak. The world is changing everyday: little by little and humanity is falling behind.
Due to our world turning into machinery: factories, an automotive future: where humans only job to live (entrance) and to die (exit) the famous humans remembered and the flawed not recalled.

This is according to Shakespeare’s imagery.

I don’t know what grade your in, but I think simplifying Shakespeare’s word of mouth in your essay would be handy and useful as it has strong references of your quote, and agrees strongly in your essay.

Hope this helps 🙂

_____ is(are) released when blood glucose levels drop.

[ad_1]

The blood type is B+. The blood type depends on some protein substances called antigens present on the cell membrane of the red blood cells that help the cells to identify and communicate with each other. There are four types of blood types;
1- Blood type A which have antigens A on the red blood cells.
2- Blood type B which have antigens B on the red blood cells.
3- Blood type AB which has antigens A and B on the red blood cells.
4- Blood type O which have no antigens on the red blood cells.
There is a second type of antigens present on the red blood cells which is called rhesus. Rhesus may be present, so the individual will be positive (+) rhesus), or it may be absent, so the individual will be negative (-) rhesus.
To determine the blood type, we add anti-a and anti-b serums to two samples of the tested blood.
If the anti-a coagulates only, the person is blood type A.
If the anti-b coagulates only, the person is blood type B.
If the two samples coagulate, the person is blood type AB.
If the two samples don’t coagulate, the person is blood type O.
To another blood sample from the same blood, we add anti rhesus, if it coagulates, the person is )+), if not the person is (-).

How many electrons do the elements of the most stable group have in their outer energy levels

I think you mean the energy of a particle attached to a spring. In that case the total energy is given by

E=K+P=12mv2+12kx2E=K+P=12mv2+12kx2Where mm is the mass of the particle, vv is the velocity of the particle, and xx is the distance of the particle from the origin. So, the maximum of potential energy PP is given when the kinetic energy KKis zero (i.e. when v=0v=0, in the turning points of the particle). In that case E=PmaxE=Pmax. SoE=Pmax=12kx2maxE=Pmax=12kxmax2here xmaxxmax is the maximum stretch of the spring (i.e. the turning point, v=0v=0).

In the other hand, the maximum of kinetic energy is given when P=0P=0 (it occurs when x=0x=0), i.e. E=KmaxE=Kmax, or

E=Kmax=12mv2maxE=Kmax=12mvmax2where vmaxvmax is the maximun velocity of the particle, it occurs when the particle passes through the origin (i.e. when x=0x=0).
