The "median" value in a list of numbers is the "middle" value. To find the median, arrange your data in numerical order from smallest to greatest. First, make a list of how many hurricanes occurred in each decade:
20, 15, 12, 17, 15, 19, 9
Then arrange them as follows:
9, 12, 15, 15, 17, 19, 20
There are seven numerals in total, thus the fourth number is the one in the middle. Because the fourth number is 15, the median is 15.
The cladogram demonstrates that dinosaurs and crocodiles are linked. They each have an amniotic egg and two post-orbital fenestrae. Amphibians diverged before either of these changes, making them less closely related. Because primates and sharks are on separate branches of this cladogram, primates did not develop from sharks. The cladogram demonstrates that all of these species' ancestors were vertebrates, although the shark's progenitor did not have a skeletal skeleton. Ray-finned fish diverged prior to the evolution of the amniotic egg.
If you remember that a meter is made up of 1000 millimeters, you can simply divide 17.3 by 1000. You can alternatively make the conversion in two phases using the information provided. To begin, divide.173 by 100 to convert to decimeters. Then, divide the result of decimeters to meters by ten to reach the final value of .0173.
Arrows lead from hares to gazelles to cheetahs. This implies that cheetahs consume hares and gazelles. Adding additional cheetahs would rapidly reduce these populations. Long-term impacts would be more difficult to predict.
In accordance to the paragraph, genetically engineered crops have the potential to increase crop productivity. If genetically engineered crops were prohibited, the result would be less food available.
It proposes that while employing hybrid electric vehicles benefits the environment by reducing our reliance on fossil fuels, it comes with a cost to the ecosystem due to the harmful methods required for the exploitation of the limited resources required by these vehicles. The section contained this information.
Only one variable can be tested in an experiment. As a result, the type of flashlight used should be the same for each battery tested, as the purpose of the experiment was to put battery producers' claims to the test.
According to the statement, hybrid vehicles are "much more efficient in their use of fossil fuels" This implies that they do need certain fossil fuels like gasoline to function.
We can see from the equation that the age multiplied by 4.7 will be removed from the BMR. As a result, multiplying a larger amount by 4.7 subtracts more from the BMR, lowering it.
The question specifies the mechanical advantage and input force; the first step is to enter these values into the equation: /br>
8= x/40
Multiply each side by 40 to solve: br>
8 × 40 = x
x = 320
The difference between the highest and lowest values in a set of data is defined as its range. Because the highest number is 20 and the lowest value is 9, the range is as follows: 20 − 9 = 11
The "mode" is the most often occurring value. In this data set, the number 15 appears twice. Because all other numbers appear just once, the mode is 15.
The complex structure of the plasmalemma, or plasma membrane, is made up of phospholipids, proteins, glycolipids, and cholesterol. The phospholipids divide into two layers, preventing water-soluble substances and dissolved ions from passing through the plasmalemma. Because of this, the plasmalemma is effective at separating the cytoplasm from the fluid environment around it.
By looking at the diagram, you may estimate that blue has a wavelength just above 450, around midway between 400 and 500 nm.
The arithmetic mean, also known as the average, is a way to define the center of a data set. It is calculated by adding the data points of a data set and dividing by the total number of data points in the set. In this case, the data set is the average time, which contains 6 data points. Add the individual times and divide by 6 to calculate the mean time:
Mean = (103 + 110 + 116 + 125 + 116 + 144) ÷ 6
Mean = 714 ÷ 6
Mean = 119
The carrying capacity of a biological species in an environment is the maximum population number of the species that the environment can support permanently, given the availability of food, habitat, water, and other prerequisites. The population trend line in this chart begins to plateau about 10,500, indicating that this is the island's carrying capacity. When a population exceeds the carrying capacity of its ecosystem, it causes a shortage of resources, which leads to an increase in the mortality rate, bringing the population back into balance.
The hyena is a primary user of grass, a secondary consumer of zebra, and a scavenger of dead wildebeest.
The issue with the group arrangement is that there is no control group. A control group is one that is not given any therapy. To evaluate the impact of the treatment, the results of the treated groups should be compared to the results of the control group. The flu vaccine was administered to all four groups in this investigation. A no-dose group should have been included to see how many flu cases happened without the vaccine.
Children with the BB gene will have brown hair, however, no children have this combination of genes. Children with the Bb gene will have brown hair (since B is dominant), and two out of every four children, or 50%, will have brown hair. Children with the gene bb have red hair, and two out of every four have red hair.
The recessive gene for green eyes is allele 'a,' and one parent has brown eyes while simultaneously possessing the recessive green eye allele. This suggests that the dominant gene (A) is responsible for brown eyes. An examination of the square reveals that half of the children will have green eyes (aa) and the other half will have brown eyes (Aa).
