Answer:

35280ways

Step-by-step explanation:

let X be the number of ways the letters can be arranged with no restriction,

let M be the number of ways they can be arranged if the letters C and O must stand together,

and let the number of ways the letters C and O can be arranged if they can not stand together.

X=8!

M= 7!

N=X–M=8!–7!=35280 ways

Answer: a) 10

Step-by-step explanation:

Buscando en google, encuentro que la expresión es:

C(x) = 9*x^2 - 80*x - 100

Queremos encontrar el valor de x (positivo), tal que esa expresión sea igual a cero, entonces tenemos que resolver:

9*x^2 - 80*x - 100 = 0.

Para ello podemos recordar la ecuación de Bhaskara, que para una ecuación de la forma:

a*x^2 + b*x + c = 0

Las soluciones son:

\(x = \frac{-b +-\sqrt{b^2 - 4*a*c} }{2a}\)

en este caso, tenemos:

a = 9

b = -80

c = -100

Entoces, las soluciones van a ser:

\(x = \frac{-(-80) +- \sqrt{(-80)^2 - 4*9*(-100)} }{2*9} = \frac{80 +- 100}{18}\)

Entonces las dos soluciones son:

x = (80 - 100)/18 = -20/18 = -10/9

Esta solución la descartamos, pues es negativa. La otra solución es:

x = (80 + 100)/18 = 180/18 = 10

La opción correcta es a: 10

The number of oatmeal cookies when Brenda ordered 12 dozen cookies from the bakery is 18.

Since Brenda ordered 12 dozen cookies from the bakery, the total number ordered will be:

= 12 × 12

= 144 cookies

Since 1/3 of them or peanut butter 1/6 of the cookies are ice 3/8 of the cookies are chocolate, the fraction for oatmeal will be:

= 1 - (1/3 + 1/6 + 3/8)

= 1 - 7/8

= 1/8

The oatmeal cookies will be:

= 1/8 × 144

= 18

Answer:

A. Genevieve

B. Sierra

Step-by-step explanation:

Genevieve uses 5 balloons per animal, but Sierra uses 6. We can find this by subtracting 360 from 440 (which gets us 80). To find the unit rate, we divide 20 into 80 (the amount of balloons used when she made 20 animals), and we get 4. So, Sierra uses 4 balloons per animal.

Since Genevieve uses more balloons per animal and started with less balloons than Sierra (she started with 425, versus Sierra, who started with 440), Sierra will have made more animals by the end of the day.

Step-by-step explanation:

After then, there must be some closed interval A between 0 and 1 such that x is less than A. As a result, x must fall between 0 and 1, as was intended.

This is further explained below.

Generally, Let A represents the set of all of the closed intervals that are included in (0, 1). Our contention is that A = (0, 1). To demonstrate this, let's begin by demonstrating that the left-hand side contains the right-hand side in its entirety.

Let x ∈ (0, 1). Our goal is to demonstrate that there is at least one A A such that x A. We may define A to be the closed interval [x, x] that contains the single point x. Alternatively, if you don't wish to state that a point is an interval, we can take A to be something like [x/2, x] or [x/2, (x + 1)/2] as an alternative.

In conclusion, because x > A > A, we may deduce that x > A A A. Now we will perform the confinement in the other direction. Let's say that x > AA A.

If this is the case, there must be some closed interval A between 0 and 1 such that x falls inside A. Therefore, x should be between 0 and 1, as required.

Step-by-step explanation:

We need to  know about margin of error to solve the problem. The factors that influence margin of error are confidence level and sample size.

Margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result will reflect the result of a census of the entire population. Margin of error is influenced by three factors, confidence level, sample size and population standard deviation. In absence of population standard deviation, the margin of error is influenced by confidence level and sample size.

Therefore the margin of error is influenced by confidence level and sample size.

Answer:

When we say that an allele is "fixed," it means that a particular allele has reached a frequency of 100% in a population.

Step-by-step explanation:

Alleles are different forms of a gene that occupy the same position on homologous chromosomes. In a population, different alleles can exist for a specific gene. However, through various evolutionary processes such as natural selection, genetic drift, or gene flow, one allele may become predominant and eventually fixate within the population.

The fixation of an allele can occur through different mechanisms. For example, if a beneficial allele provides a selective advantage to individuals carrying it, it is more likely to increase in frequency and eventually become fixed in the population. On the other hand, genetic drift, which is the random change in allele frequencies due to chance events, can also lead to the fixation of an allele, especially in small populations.

Once an allele is fixed in a population, it means that all future generations will inherit that allele, and no alternative alleles will be present at that particular gene locus.

In a simple linear regression model, the coefficient of the independent variable (x) in the estimated sample regression equation indicates the change in the predicted value of the dependent variable (y) when x increases by one unit. This coefficient is also known as the slope of the regression line. Therefore, to calculate the predicted value of y, we multiply the coefficient by the value of x and add the intercept.

In a simple linear regression model, the coefficient that indicates the change in the predicted value of y when x increases by one unit is the "slope coefficient" or the "regression coefficient" (usually denoted as b1). This coefficient represents the relationship between the independent variable x and the dependent variable y.

The linear regression equation is given as:

y = b0 + b1 * x

Where:
- y is the predicted value of the dependent variable
- b0 is the intercept coefficient (where the line intersects the y-axis)
- b1 is the slope coefficient (the change in y when x increases by one unit)
- x is the independent variable

In this equation, b1 indicates the change in the predicted value of y when x increases by one unit.

A quarterback completed 59% of his passes for a total of 265 yards and 2 touchdowns. The value "59%" is a statistic.

In this scenario, a sample of the quarterback's passes was taken during the championship football game, and the completion percentage was calculated based on that sample. Since the percentage was calculated based on a sample, it is a statistic. A parameter, on the other hand, is a value that describes a characteristic of an entire population. For example, if we were to consider the completion percentage of all quarterbacks in the league, then the mean or median completion percentage would be a parameter because it would describe a characteristic of the entire population of quarterbacks. In summary, statistics are values that describe a characteristic of a sample, while parameters are values that describe a characteristic of a population.

Determine whether the underlined value is a parameter or a statistic. In a championship football game, a quarterback completed 59% of his passes for a total of 265 yards and 2 touchdowns. Is the value a parameter or a statistic?

Answer:

y + 2x = -4

Step-by-step explanation:

y - 4 = -2(x-(-4))

Standard form is Ay + Bx = C

Where A and B are coefficients of x and y and C is a constant.

To convert the given equation in standard form we must get x and y on one side and the constant on the other.

y - 4 = -2(x-(-4))

==> apply double negative rule

y - 4 = -2(x+4)

==> distribute -2

y - 4 = -2x - 8

==> we want to get x on the side with y, to do so we add 2x to both sides

y + 2x - 4 = -8

==> finally we want to get the constant by itself or get rid of -4 on the left side and onto the right , so to do so we add 4 to both sides

y + 2x =  -4

And we are done!

The equation in standard form , Ax + By = C is y + 2x = -4

We know this is correct because both x and y are on one side and the constant -4 , is on the other

We can also double check our answer by graphing.

If you check the attached image we notice that the two lines , created by the given equation and the equation in standard form overlap meaning our answer is correct.

The equation \(2c \times a \times e^{c^2} = f(a) - f(-a)\)represents the condition where the instantaneous rate of change of f equal the average rate of change of f on that interval.

To begin, let's first establish what average rate of change and instantaneous rate of change mean.

Mathematically, it can be calculated as:

Average Rate of Change = (f(b) - f(a)) / (b - a)

On the other hand, the instantaneous rate of change of a function f(x) at a specific point x = c is defined as the slope of the tangent line at that point. This can be found by taking the derivative of the function and evaluating it at x = c. In mathematical terms, it is represented as:

Instantaneous Rate of Change = f'(c)

Now, let's apply these concepts to the given function \(f(x) = e^{x^2}\) and the interval [-a, a]. To determine the average rate of change over this interval, we need to find the values of f(a) and f(-a) and calculate the difference divided by 2a:

Average Rate of Change = (f(a) - f(-a)) / (2a)

To find the instantaneous rate of change, we need to take the derivative of f(x) and evaluate it at x = c:

\(f'(x) = 2x \times e^{x^2}\)

Instantaneous Rate of Change = \(f'(c) = 2c \times e^{c^2}\)

Now, we want to find the points within the interval [-a, a] where the instantaneous rate of change is equal to the average rate of change. Therefore, we can set up the following equation:

\(f'(c) = 2c \times e^{c^2}\) = (f(a) - f(-a)) / (2a)

Simplifying this equation, we can multiply both sides by 2a to eliminate the denominator:

\(f'(c) = 2c \times e^{c^2}\)  = f(a) - f(-a)

Based on the results of the linearhypothesis function, we can conclude whether the hypothesis in part (b) is supported or not.

Linear hypothesis is a method of testing statistical hypotheses by estimating the parameters of a linear equation. This method of testing hypotheses involves estimating the parameters of a linear equation using a sample of data to determine if the parameters differ significantly from zero.

We can estimate the given model using the data in vote1. To do this, we will fit a linear regression model with the two independent variables (a's expenditures and b's expenditures) and the dependent variable (outcome). We can then use the model to determine whether a's expenditures have an effect on the outcome. We can do this by testing whether the coefficient for a's expenditures is statistically significant. If the coefficient is not statistically significant, then this means that a's expenditures do not have an effect on the outcome. We can also use the model to determine whether b's expenditures have an effect on the outcome. We can do this by testing whether the coefficient for b's expenditures is statistically significant. If the coefficient is not statistically significant, then this means that b's expenditures do not have an effect on the outcome. These results can be used to test the hypothesis in part (b). We can use the linearhypothesis function to test the hypothesis at a 5% significance level. If the test is found to be statistically significant, then this means that the hypothesis is supported. If the test is not statistically significant, then this means that the hypothesis is not supported.  Based on the results of the linearhypothesis function, we can conclude whether the hypothesis in part (b) is supported or not.
