The owner of a pet store sells 5 goldfish for $9 . What is the cost in dollars for one goldfish

The dimensions of the rectangle are;

length = 1 inch and width = 4 inches.

The whole distance that a rectangle borders, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the total of its four sides.

Given:

The width of a rectangle is 7 inches less than 2 times its length.

Let the length be n inches.

So, the width is 2n - 7 inches.

The perimeter of the rectangle = 10 inches.

2(n + 2n -7) = 10

3n = 5 + 7

3n = 12

n = 4.

And the length is 1 inch.

Therefore, the dimension is 1 by 4 inches.

Answer:

Step-by-step explanation:

One clue about where to start is this: the sentence describes the length by referring to the width. "The LENGTH is blah, blah, blah, the WIDTH. When that happens, choose a variable to represent the width (the quantity being referred to).

Width = w

Length IS three more than (added to) 4 times (multiplied by) the width

Length = 4w + 3

Area of a rectangle is the width multiplied by the length.

Equation: w(4w + 3) = 24

Solve.

Multiply out the left side.

4w^2 + 3w = 24

Subtract 24.

4w^2 + 3w -24 =0

This equation does not factor. Use the Quadratic Formula. One of the solutions is a negative number, so that should be rejected (width can't be a negative number).

\(w=\frac{-3+\sqrt{393}}{8}\)

Substitute this into the expression 4w + 3 to find the length. A calculator can give you decimals for both dimensions.

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

Answer: y = (1/8)x + 3.625

Step-by-step explanation:

slope: y = mx + b

change from 3 to 4 is 1, this is our rise

change from -5 to 3 is 8, this is our run

1/8 = m

this is a really bad explanation but I know that

1/8 is equal to 0.125.

since there are 5 spaces from (-5,3) to the y axis, and that the slope is 1/8, i can multiply 1/8 x 5 to get 5/8.

5/8 =.625

since the x intercept is in between 3 and 4, it is 3.625.

3.625 = b

To find the value of y₁(2), we can use the given differential equation and the initial condition y(1) = 4.  The differential equation is dy/dx = (2y - 5x² + 3) / x. We want to find the particular solution y₁(x) that satisfies this equation. First, we integrate both sides of the equation:

∫dy = ∫(2y - 5x² + 3) / x dx

This gives us y = 2yln|x| - (5/3)x³ + 3x + C, where C is the constant of integration. Next, we substitute the initial condition y(1) = 4 into the equation:

4 = 2(4)ln|1| - (5/3)(1)³ + 3(1) + C

4 = 8ln(1) - 5/3 + 3 + C

4 = 0 + 2/3 + 3 + C

C = 4 - 2/3 - 3

C = 11/3

So the particular solution y₁(x) is given by:

y₁(x) = 2yln|x| - (5/3)x³ + 3x + 11/3

To find y₁(2), we substitute x = 2 into the equation:

y₁(2) = 2y₁ln|2| - (5/3)(2)³ + 3(2) + 11/3

y₁(2) = 2y₁ln(2) - 40/3 + 6 + 11/3

y₁(2) = 2y₁ln(2) - 23/3

Therefore, the value of y₁(2) is 2y₁ln(2) - 23/3.

y = -2x - 5

Step-by-step explanation:

y = is a standard for any equation, as is the use of x as a variable, unless something else is specified.

-2x is the way to denote a slope of -2, and -5 gives you the y-intercept of 5. One point on this line would be (0, -5).

The frequency of the allele for non-tasting PTC in the population is 0.09 or 9%.

To determine the frequency of the allele for non-tasting PTC in a population where the frequency of PTC tasters is 91%, we can use the Hardy-Weinberg equation. The Hardy-Weinberg principle describes the relationship between allele frequencies and genotype frequencies in a population under certain assumptions.

Let's denote the frequency of the allele for taster individuals as p and the frequency of the allele for non-taster individuals as q. According to the principle, the sum of the frequencies of these two alleles must equal 1, so p + q = 1.

Given that the frequency of PTC tasters (p) is 91% or 0.91, we can substitute this value into the equation:

0.91 + q = 1

Solving for q, we find:

q = 1 - 0.91 = 0.09

Therefore, the frequency of the allele for non-tasting PTC in the population is 0.09 or 9%.

It's important to note that this calculation assumes the population is in Hardy-Weinberg equilibrium, meaning that the assumptions of random mating, no mutation, no migration, no natural selection, and a large population size are met. In reality, populations may deviate from these assumptions, which can affect allele frequencies. Additionally, this calculation provides an estimate based on the given information, but actual allele frequencies may vary in different populations or geographic regions.

There are 11,440 ways to distribute 7 identical flyers into 10 different mailboxes, where each mailbox receives at most one flyer.

If we are allowed to put at most one flyer per mailbox and the flyers are identical, this problem involves distributing identical objects into distinct containers. The solution can be obtained using the stars and bars method.

We can represent the distribution of flyers as 7 stars (representing the flyers) and 9 bars (representing the dividers between the mailboxes). The number of ways to distribute the flyers is equal to the number of ways to arrange the 7 stars and 9 bars, which is given by the binomial coefficient:

${{7 + 9}\choose{9}} = {{16}\choose{9}} = \frac{16!}{9!7!} = 11440$

The statement that the right-hand side variables in a regression equation are interdependent is generally false.

In a regression equation, the right-hand side variables, also known as independent variables or predictors, are typically assumed to be independent of each other. This means that the values of one variable should not be influenced by the values of other variables included in the equation.

The assumption of independence is important in regression analysis because it allows us to assess the individual contribution of each independent variable in explaining the variation in the dependent variable. By assuming independence, we can isolate the effect of each predictor and determine its significance in predicting the outcome.
When the right-hand side variables in a regression equation are interdependent, it can lead to issues such as multicollinearity. Multicollinearity occurs when two or more independent variables are highly correlated with each other, making it difficult to separate their individual effects on the dependent variable. This can result in unstable or unreliable estimates of the regression coefficients.

However, it is important to note that there may be situations where some degree of interdependence or correlation between predictors is expected or even desirable. For example, in some cases, including interaction terms or polynomial terms in the regression equation may involve interdependence between variables to capture more complex relationships. In such cases, the assumption of independence is relaxed or modified to accommodate the specific research question or hypothesis being investigated.
