Actual lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy length with a standard deviation of 11 days. About
what percentage of births would be expected to occur more than 22 days after the mean pregnancy length?
About 2.28% of births would be expected to occur more than 22 days after the mean pregnancy length.
What is percentage?
Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".
Since the lengths of pregnancy terms are nearly normally distributed with a mean pregnancy length and a standard deviation of 11 days, we can use the properties of the normal distribution to answer this question.
Let X be the length of pregnancy terms, then X ~ N(μ, σ) where μ is the mean pregnancy length and σ is the standard deviation.
We want to find P(X > μ + 22), which is the probability that a birth occurs more than 22 days after the mean pregnancy length.
Using the standard normal distribution, we can standardize X as follows:
Z = (X - μ) / σ
Since X ~ N(μ, σ), then Z ~ N(0, 1).
Therefore, P(X > μ + 22) = P(Z > (22/σ)) = P(Z > (22/11)) = P(Z > 2)
Using a standard normal distribution table or calculator, we can find that the probability of Z being greater than 2 is approximately 0.0228.
So, about 2.28% of births would be expected to occur more than 22 days after the mean pregnancy length.

what is matrix ?A matrix is a collection of numbers that are organised in rows and columns. Learns about matrix elements and dimensions and introduces them for the first time. A matrix is a rectangular grid of numbers in rows and columns. Matrix A, for example, has two rows and three columns. Its name is derived from its single row and 1 n row matrix order. For example, A = [1 2 4 5] is a row matrix of order 1 by 4. Another example of a row matrix is P = [-4 -21 -17] of order 1-by-cubic.
To identify a basis for the R3 subspace V' spanned by the vector v = [1, 1, 0], we must first determine a set of linearly independent vectors that span V'.
One option is to row-reduce the augmented matrix [v|0] using the Gaussian elimination method, where 0 is the zero vector in R3.
[1 1 0 | 0]
[1 1 0 | 0]
[0 0 0 | 0]
This demonstrates that the vector v = [1, 1, 0] spans an R3 one-dimensional subspace, implying that any nonzero scalar multiple of v is also in V'.
As a result, a basis for V' is the set v, which consists solely of the vector v itself.

A proportion often shows the relationship between:
Answer: two related quantities by comparing their ratios and establishing equivalence.
Step-by-step explanation: A proportion is a mathematical statement that equates two ratios. It is commonly used to express the relationship between two related quantities or sets of data. A proportion consists of four values: two ratios, where each ratio is made up of a numerator and a denominator.
Proportions are useful for comparing and understanding the relationship between different quantities. They can be used to solve various real-life problems, such as determining equivalent values, finding unknown quantities, or making predictions based on known information.
For example, if a recipe calls for 2 cups of flour and 1 cup of water, the proportion would be 2:1. This proportion shows the relationship between the amount of flour and water needed in the recipe.
In a proportion, the ratios are equivalent, meaning they have the same value. This equality allows us to solve for unknown quantities by cross-multiplying and finding the missing value.

The function (fog)(x) is 4x² - x - 3.
Define functionIn mathematics, a function is a rule that maps each element from a set (called the domain) to a unique element in another set (called the range or codomain).
In other words, a function is a mathematical object that takes one or more inputs, performs a specified operation on them, and produces an output. The input values of a function are called its arguments, and the output value is called the function value.
Starting with g(x):
g(x) = -4x² + x + 5
Now substituting g(x) into f(x):
f(g(x)) = -(g(x)) + 2
= -[-4x² + x + 5] + 2 (substituting g(x) into f(x))

Find the probability of numbers lying between 500 and 900 inclusive with exactly two consecutive figures are identical.
Answer:
To find the probability of numbers lying between 500 and 900 inclusive with exactly two consecutive figures that are identical, we can use the following steps: Step 1: Count the total number of three-digit numbers between 500 and 900 inclusive. There are 400 three-digit numbers between 500 and 900 inclusive. Step 2: Count the number of three-digit numbers between 500 and 900 that have exactly two consecutive figures that are identical. We can break this down into cases based on the middle digit of the three-digit number. Case 1: The middle digit is not 0 or 9. In this case, there are 8 possible digits that can be used for the middle digit (i.e., 1, 2, 3, 4, 5, 6, 7, or 8). For each possible middle digit, there are
For a fixed location, the number of sunlight hours in a day fluctuates throughout the year. Suppose that the number of daily sunlight hours in a particular location can be modeled by the following.
Using trigonometric equation, we can find that on January 25th, 218 days after June 21st, there will be 11 hours of sunlight.
Define trigonometric equation?The trigonometric equations can be linear, quadratic, or polynomial equations and are conceptually related to algebraic equations. Trigonometric equations substitute the Sin, Cos, and Tan trigonometric ratios for the variables found in a typical polynomial equation. Sinθ, Cosθ, or Tanθ are the trigonometric ratios that are employed in trigonometric equations.
The number of daily sunlight hours of a particular location is modelled by the trigonometric equation,
l(t) = 12 + 3.5sin (2/365t)
L(t) denotes the number of hours of sunlight in a day.
t is the number of days after June 21st.
In order to find the day during the first 365 where there are 11 hours of sunlight, we must know the value of "t" for which L(t) = 11 hours. The result of solving for t in the given equation with L(t)=10 is as follows:
l(t) = 12 + 3.5sin (2/365t)
11 = 12 + 3.5sin (2/365t)
11-12 = 3.5sin (2/365t)
-1 = 3.5sin (2/365t)
-1/3.5 = sin (2/365t)
-0.285 = sin (2/365t)
For the inverse function of y = sin x
sin ⁻¹(y) =x + 2n
Given that we must determine the day with 11 hours of sunlight in the first 365 days, we get the following results when we set n=0: t = -35.3521 or t =217.9422.
Now, t cannot be negative since we want to discover that the day after June 21st will have 10 hours of sunlight. therefore, ignoring t=-35.3521. We now have t=217.9422.
By rounding, we arrive at the necessary response, t=218.
So, it will have 11 sunlights on January 25th—218 days after June 21st.

Given: The ratio of pickups to cars sold at a dealership is 2 to 3. If the dealership sold 142 more cars than pickups in 1999
Let y = the number of cars.
x/y = 2/3.
The dealership sold 142 more cars than pickups.
We get y = x + 142
In the equation of x/y = 2/3, replace y with x + 142 to get:
x/(x+142) = 2/3
cross multiply to get:
3x = 2*(x+142)
simplify to get:
3x = 2x + 284
subtract 2x from both sides of the equation to get:
x = 284.

Explain the relationship between prejudice and discrimination? What are some ways to combat both prejudice and
discrimination? Identify and provide an example of two of the following intergroup relationships: assimilation, segregation,
pluralism, expulsion, amalgamation, or genocide.
Answer:
Prejudice and discrimination are related concepts that are often seen together in intergroup relations. Prejudice refers to preconceived opinions, attitudes, or beliefs about a group or individual based on their membership in a particular social group. Discrimination, on the other hand, refers to actions that are based on prejudice and that result in unequal treatment or opportunities for individuals or groups.
The relationship between prejudice and discrimination is that prejudice often leads to discrimination. When individuals or groups hold prejudiced beliefs about others, they are more likely to engage in discriminatory actions towards them. Discrimination can take many forms, including social exclusion, harassment, violence, and unequal access to resources and opportunities.
One way to combat both prejudice and discrimination is through education and awareness-raising campaigns. By educating individuals and communities about the harmful effects of prejudice and discrimination, people can learn to recognize their own biases and work to eliminate them. Other strategies include promoting diversity and inclusion in workplaces, schools, and other social settings, and providing equal opportunities for all individuals regardless of their background.
An example of intergroup relationships could be segregation and pluralism. Segregation refers to the physical separation of different groups within society, often based on factors such as race or ethnicity. An example of segregation is the historical segregation of African Americans in the United States, where they were denied access to many public spaces, such as schools and restaurants.
Pluralism, on the other hand, refers to the coexistence of different cultural and ethnic groups within society. In a pluralistic society, individuals and groups are free to express their cultural identities and customs without fear of discrimination or prejudice. An example of pluralism is Canada, which has a multicultural policy that recognizes and celebrates the diversity of its citizens while promoting equal opportunities and rights for all.
