In stabilizing selection, what occurs in a population?a. The population shifts toward one of two extreme phenotypes.b. Both extreme phenotypes shift toward the middle.c. The intermediate phenotype becomes more common.d. The intermediate phenotype becomes rare.
In stabilizing selection, option (d) The intermediate phenotype becomes rare.
Stabilizing selection occurs when individuals with extreme phenotypes are at a disadvantage, and individuals with intermediate phenotypes have a greater chance of survival and reproduction.
This means that over time, the population shifts towards the intermediate phenotype. Let's take an example to explain this concept.
Suppose we have a population of rabbits with different fur colors, ranging from white to dark brown. Predators are more likely to spot white rabbits in a snowy environment, while brown rabbits are more likely to be seen in a forest environment. This means that the extreme phenotypes (white and dark brown) are at a disadvantage, while the intermediate phenotype (light brown) is more likely to survive and reproduce. Over time, the population will shift towards the light brown phenotype, as it is the most advantageous trait.
In conclusion, stabilizing selection is a mechanism of natural selection that promotes the preservation of the average characteristics of a population. It occurs when individuals with intermediate phenotypes have a higher chance of survival and reproduction, leading to the shift of the population towards the intermediate phenotype. Mathematically, we can represent this concept using the mean and standard deviation of a population.

The length of the hypotenuse of a right triangle with legs measuring 20 inches and 28 inches is approximately 34.4 inches, found using the Pythagorean theorem.
The length of the hypotenuse of a right triangle with legs measuring 20 inches and 28 inches can be calculated using the Pythagorean theorem, which states that the square of the sum of the squares of the lengths of the legs determines the length of the hypotenuse.
So, if we call the length of the hypotenuse "h", we have [tex]h^{2}[/tex] = [tex]20^2 + 28^2[/tex]
Solving for h:
[tex]h^2 = 20^2 + 28^2[/tex]
[tex]h^2[/tex] = 400 + 784
[tex]h^2[/tex] = 1184
h = [tex]\sqrt{1184}[/tex]
h ≈ 34.4 in.
So, the length of the hypotenuse is approximately 34.4 inches, rounded to the nearest tenth.
The Pythagorean theorem is a fundamental mathematical relationship that states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal tothe squared lengths of the two legs added together. In this case, the two legs have lengths of 20 inches and 28 inches, and the length of the hypotenuse can be found by solving for the square root of the total of the leg squares.

Anna ate 5/8 of an orange and gave the other 3/8 to her brother.
The difference between the amount Anna ate and the amount she gave to her brother can be found by subtracting 3/8 from 5/8. This can be expressed as an equation by writing 5/8 - 3/8 = x, where x is the difference.
5/8 - 3/8 = x
5/8 = 5 ÷ 8
= 0.625
3/8 = 3 ÷ 8
= 0.375
0.625 - 0.375 = x
= 0.25
Therefore, the difference between the amount Anna ate and the amount she gave to her brother is 0.25.The difference between the amount Anna ate and the amount she gave to her brother can be found by subtracting 3/8 from 5/8. This can be expressed as an equation by writing 5/8 - 3/8 = x, where x is the difference. To solve this equation, we first need to convert the fractions into decimal values. 5/8 is equal to 5 divided by 8, which is equal to 0.625. 3/8 is equal to 3 divided by 8, which is equal to 0.375. We can then subtract 0.375 from 0.625 to get the difference. This gives us 0.25, which is the difference between the amount Anna ate and the amount she gave to her brother. Therefore, the answer to the equation 5/8 - 3/8 = x is x = 0.25.

Bob bought 40 gumboils from a quarter machine. The number of each flavor he got is shown in the table. If there are 140 gumboils remaining in the machine. what is a reasonable prediction for the number of cola flavored gumboils left?
Answer: Is only definable if you can show the table but according to a valid explanation it would be most likely 41
Step-by-step explanation:
Lets say Bob has 17 strawberry, 19 Cola, and 4 blueberry, we can infer there is an equal amount of gumballs of each flavor in the machine; Before bob bought any gumballs there were 180 and if there were only 3 flavors we would divide 180 by 3 and get 60. That means each flavor has 60 of its own flavor and if we take 19 from the 60 cola flavored we can get 41.

Relative to a fixed origin O, the point A has position vector (2i + 3j - 4k), the point B has position vector (4i - 2j + 3k), and the point C has position vector (ai + 5j – 2k), where a is a constant and a < 0.
D is the point such that AB = BD.
(a) Find the position vector of D.
Given AC| = 4,
(b) find the value of a.
Answer: (a) To find the position vector of point D, we need to find the midpoint of the line segment AB. We can do this by taking the average of the position vectors of points A and B:
D = (A + B) / 2 = ((2i + 3j - 4k) + (4i - 2j + 3k)) / 2 = (3i + 0.5j - 0.5k)
So, the position vector of point D is (3i + 0.5j - 0.5k).
(b) To find the value of a, we use the fact that the distance between points A and C is 4. We can find the distance between two points by finding the magnitude of the difference between their position vectors. The position vector of point C is (ai + 5j – 2k), so the difference between the position vectors of points A and C is (ai + 5j – 2k) - (2i + 3j - 4k) = (a-2)i + 2j - (-2k).
The magnitude of this difference is given by:
|(ai + 5j - 2k) - (2i + 3j - 4k)| = √((a-2)^2 + 2^2 + 2^2) = 4
So, we have:
√((a-2)^2 + 2^2 + 2^2) = 4
(a-2)^2 + 2^2 + 2^2 = 16
(a-2)^2 = 16 - 4 - 4
(a-2)^2 = 8
a-2 = ±2√2
Since a < 0, we have:
a = 2 - 2√2
So, the value of a is 2 - 2√2.
Step-by-step explanation:
A house has decreased in value by 38% since it was purchased. If the current value is $93,000, what was the value when it was purchased?
The value of the house when it was purchased was $150,000, before the 38% discount was applied.
A discount is a reduction in price or value, typically given as an incentive to purchase or to compensate for a decline in value.
In this case, we know that the house has decreased in value by 38% since it was purchased. This means that the current value is only 62% of its original value (100% - 38% = 62%).
Now, we can use a proportion to determine the original value of the house. We can set up the equation:
Current value / Original value = 62% / 100%
Substituting the given values, we get:
$93,000 / Original value = 62 / 100
To solve for the original value, we can cross-multiply and simplify:
100 x $93,000 = 62 x Original value
$9,300,000 = 62 x Original value
Dividing both sides by 62, we get:
Original value = $150,000

what is the minimum value of y=x^2+36/5
Answer:
(36/5)
Step-by-step explanation:
y=x^2+36/5
Since x is squared, the result will always be a positive number, regardless of the actual value of x. Starting with a value of x of zero, the x^2 term will only grow as one moves away from 0. E.g., (-1)^2 = 1, (-2)^2 = 4, etc.
So the minium for this equation will occur when x = 0. It only gets larger from that point. The minimum is (36/5).

Why greater than less than negative 2X squared +16 X -36
Answer:
Step-by-step explanation:
To determine whether a value is greater than or less than a specific result from an equation, you would need to substitute the value into the equation and solve for the result. For example, if you want to determine if the value "a" is greater than or less than the result of the equation -2x^2 + 16x - 36, you would substitute "a" for the variable x and solve for the result:
-2x^2 + 16x - 36 = -2a^2 + 16a - 36
Then you can compare the value of the result to "a" to determine whether it is greater than or less than.
If the result is greater than "a", you would write:
-2a^2 + 16a - 36 > a
If the result is less than "a", you would write:
-2a^2 + 16a - 36 < a
And if the result is equal to "a", you would write:
-2a^2 + 16a - 36 = a
It's important to note that the comparison only holds for a specific value of "a". The equation -2x^2 + 16x - 36 could have many solutions where the result is greater than, less than, or equal to "a".
