Explanation:
Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.
30, 26, 25, 11, 34, 20, 26, 26
a.
Mean = 99
Median = 26
Mode = 26
c.
Mean = 24.8
Median = 34
Mode = 26
b.
Mean = 24.8
Median = 26
Mode = 25
d.
Mean = 24.8
Median = 26
Mode = 26
Please select the best answer from the choices provided
A
B
C
D
Answer:
D.
Mean: 24.8
Median: 26
Mode: 26
Explanation:
The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.
30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198
Now, we divide by how many numbers we started out with (8).
198 divided by 8 = 24.75, rounded would be 24.8
To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:
11, 20, 25, 26, 26, 26, 30, 34
As you can see, the middle number is 26.
To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.
11, 20, 25, 26, 26, 26, 30, 34
As you can see, the number 26 appears the most often.
So, we end up with:
Mean: 24.8
Median: 26
Mode: 26

How is a gas different than a liquid
Answer:
Liquids (substances that exist in the liquid state) don't have any fixed shape and occupy a fixed volume. They are slightly compressible and take the shape of their containers. Gases (substances that exist in the gaseous state) don't have any fixed shape and don't occupy any fixed volume.

The red dots represent oxygen molecules in this diagram. This diagram shows __________.
facilitation diffusion
osmosis
diffusion
exocytosis
endocytosis
The correct answer is option B.
Diffusion is the process of movement of both the solute and solvent. the characteristic of diffusion is that it does not require a membrane or a layer separating two parts. In diffusion particles or solutes move from a region of higher concentration to a region of lower concentration.
In the example, we can see that red particles are together in a place and after some time they get distributed evenly in the entire liquid. This process is known as diffusion as it does not require a membrane.

Why is humus an effective fertilizer? (Select all that apply.)
It is abundant in inorganic nutrients.
It is dense and does not contain organic matter.
It is rich in organic matter.
It doesn’t need microorganisms to decompose matter.
The answer is: They are rich in organic matter.
Why are they rich in organic matter?
This is because humus is made out of dead plants, fruits, and sometimes even animal waste. Which is all good for growing plants.
This is the only answer because the rest are wrong.
This is a 1-1 answer, meaning this is the only one that is correct.

1. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
2. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
3. Since sickle cell disease requires two alleles that are alike, a person with a heterozygous would not have the disease.
4. If both gene alleles are different, the organism is heterozygous for that particular trait.

Hii :)
First, what is a "Gymnosperm"?
A gymnosperm is a plant that has seeds unprotected by a fruit.
Now, whats a fern?A fern is a flowerless plant that has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds.
Okay, now, what makes them different? Ferns are flowerlessFerns do not have seedsFerns are grouped into one divisonFerns have smaller speciesGymnosperms have seeds.Gymnosperms are grouped in more than one divisonGymnosperms have a larger species.Now, what do the have in common?They are both vascular They both have sporophyte dominant generationSome gymnosperm types
cycads. Palm-like plants found mainly in tropical and subtropical regions.ginkgoes: maidenhair tree. One species: Ginkgo biloba; the maidenfern tree no longer living in the wild, and only found in cultivation.gnetophytes: mormon tea, welwitschia, gnetum.conifers: pines, spruces and firs.Some types of ferns
Boston Fern Maidenhair Fern Cretan Brake Fern Bird’s Nest FernHere is paragraph form:
Gymnosperms are different because they have seeds and ferns do not. Gymnosperms also have more than one divison.Both gymnosperms and ferns are vascular. They also both have sporophyte dominant generations. So this is what makes them similar and different.

Identify the species of horse fossils that would be found in the uppermost layer of rock.
A Orohippus
B Mesohippus
C Hyracotherium
D Miohippus
Answer: I think the answer would be D miohippus
Explanation:
Miohippus would be found in the uppermost layer of rock. Therefore, option (B) is correct.
What is Miohippus?Miohippus is an extinct genus of early horse that lived in North America during the Miocene epoch, around 23 to 5 million years ago. It was a small, three-toed horse that was slightly larger than its predecessor, Mesohippus.
Miohippus had a relatively short face, with a long, narrow skull and teeth that were adapted for grinding tough vegetation. It is believed that Miohippus was the ancestor of the modern horse, and that its evolution was characterized by an increase in size, a reduction in the number of toes, and changes in the shape of the skull and teeth that allowed for a more efficient grazing diet.

Use the information to answer the following question.
The Blacklegged Tick is a parasite of the White-Footed Mouse. The White-Footed Mouse carries the bacteria which cause Lyme Disease. The bacteria are spread to ticks that bite infected mice. If an infected tick then bites a human, the human can be infected with the bacteria and develop Lyme Disease. Scientists have proposed that increased human development has led to an increase in the White-Footed Mouse population which can lead to increased cases of Lyme Disease in humans.
Answering which scientific question would BEST support the scientist’s hypothesis?
A.
Do White-Footed Mice live in forest areas?
B.
Does Lyme Disease spread to humans from ticks?
C.
Do ticks bite a mouse more than once?

are the benefits of dialysis worth the cost?
Answer:
The cost of alternative dialysis modalities for the treatment of end-stage renal disease (ESRD) was evaluated, using a societal viewpoint, in a regional nephrology program in south-western Ontario. The dialysis treatments compared were hospital hemodialysis, home hemodialysis, self-care hemodialysis, and continuous ambulatory peritoneal dialysis (CAPD). The participants were all patients treated by the same dialysis modality for the fiscal year April 1990 to March 1991. Fully allocated costs are expressed in 1993 Canadian dollars. The average costs per patient year were $88,585 for hospital hemodialysis, $55,593 for self-care hemodialysis, $44,790 for CAPD, and $32,570 for home hemodialysis. The dialysis treatment costs were $54,929 for hospital hemodialysis, $43,313 for self-care hemodialysis, $31,918 for CAPD, and $26,048 for home hemodialysis. These data quantify the magnitude of the differences between fully-allocated costs among the dialysis modalities in a regional nephrology program in Canada. The methodology used in this economic analysis can be applied to programs which differ in structure and scale. The breakdown of dialysis treatment costs into overhead, support department, personnel, supplies, and medication identifies potential areas for cost reduction strategies.
