Step-by-step explanation:

When we divide the entire equation by -1/2 to get rid of the coefficient of n we get n = 16.

Answer:

D.) 16

Step-by-step explanation:

Solve for n:

-n/2 = -8

Multiply both sides of -n/2 = -8 by -2:

(-2 (-n))/2 = -2 (-8)

-2×(-1)/2 = (-2 (-1))/2:

(-2 (-1))/2 n = -2 (-8)

(-2)/2 = (2 (-1))/2 = -1:

--1 n = -2 (-8)

(-1)^2 = 1:

n = -2 (-8)

-2 (-8) = 16:

Answer: n = 16

A) The exact cost of producing the 31st food processor is $3771.70. B)  Using the marginal cost, the approximate cost of producing the 31st food processor is $3741.40.

(A) To find the exact cost of producing the 31st food processor, we substitute x = 31 into the cost function C(x) = 1900 + 60x - 0.3x^2:

C(31) = 1900 + 60(31) - 0.3(31)^2

C(31) = 1900 + 1860 - 0.3(961)

C(31) = 1900 + 1860 - 288.3

C(31) = 3771.7

Therefore, the exact cost of producing the 31st food processor is $3771.70.

(B) The marginal cost represents the rate of change of the cost function with respect to the quantity produced. Mathematically, it is the derivative of the cost function C(x).

Taking the derivative of C(x) = 1900 + 60x - 0.3x^2 with respect to x, we get:

C'(x) = 60 - 0.6x

To approximate the cost of producing the 31st food processor using the marginal cost, we evaluate C'(x) at x = 31:

C'(31) = 60 - 0.6(31)

C'(31) = 60 - 18.6

C'(31) ≈ 41.4

The marginal cost at x = 31 is approximately 41.4 dollars.

To approximate the cost, we add the marginal cost to the cost of producing the 30th food processor:

C(30) = 1900 + 60(30) - 0.3(30)^2

C(30) = 1900 + 1800 - 0.3(900)

C(30) = 3700

Approximate cost of producing the 31st food processor ≈ C(30) + C'(31)

≈ 3700 + 41.4

≈ 3741.4

Therefore, using the marginal cost, the approximate cost of producing the 31st food processor is $3741.40.

Answer:

\(\$ \ \dfrac{428}{500}x\)

Step-by-step explanation:

Regular price of a pair of shoes = $\(x\)

Discount offered = 20%

Amount of discount offered = 20% of $\(x\)

Discounted price = Regular price - Amount of discount

Discounted price = $\(x\) - 20% of $\(x\) = 80% of $\(x\) = \(\$ \frac{4}{5}x\)

Now, it is given that there is a sales tax of 7% as well on the price.

Sales tax is applied on the discounted price.

Therefore, sales tax = 7% of \(\$ \frac{4}{5}x\)

Final Price after applying the sales tax = \(\$ \frac{4}{5}x\) + 7% of \(\$ \frac{4}{5}x\)  

\(\Rightarrow 107\%\ of\ \$\ \ \dfrac{4}{5}x\)

\(\Rightarrow \$ \ \dfrac{428}{500}x\)

Therefore, the expression to represent the final price of the pair of shoes:

Answer:

Y=COS X+1

Step-by-step explanation:

The function whose graph is given by is y = cos x + 1.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The graph of the function y = cos(x) + 1 can be understood by analyzing its two component functions:

cos(x) and 1.

The function cos(x) is a periodic function that oscillates between -1 and 1, with a period of 2π.

The graph of cos(x) is a smooth curve that has its maximum value at x = 0 and its minimum value at x = π (or x = -π).

The function 1 is a constant function that takes on the value of 1 for all values of x.

The graph of 1 is a horizontal line that extends infinitely in both directions along the x-axis.

When we add the two functions together, we get the function:

y = cos(x) + 1.

This function shifts the graph of cos(x) upward by 1 unit, so that it oscillates between 0 and 2, with a maximum value of 2 when cos(x) = 1 and a minimum value of 0 when cos(x) = -1.

The resulting graph of y = cos(x) + 1 is a periodic curve that oscillates above and below the horizontal line y = 1, with a period of 2π.

It has its maximum value of 2 when x = 2nπ (where n is an integer), and its minimum value of 0 when x = (2n + 1)π (where n is an integer). The graph is symmetric about the line y = 1, which is the horizontal asymptote of the function.

Thus,

The function whose graph is given by is y = cos x + 1.

When the relationship between the regression line and the data points is weak, it indicates a lack of strong association and highlights the need for further investigation and consideration of alternative explanations to better understand the underlying dynamics of the variables being studied.

When the relationship is weak, it implies that the data points are scattered and do not follow a clear pattern or trend. The variability in the data is high, making it difficult to establish a strong linear relationship. This could be due to various reasons, such as the presence of outliers, measurement errors, or the existence of other unaccounted factors influencing the variables.

The weak relationship between the regression line and the data points suggests that the predictive power of the regression model is limited. The regression line may not effectively explain or predict the values of the dependent variable based on the independent variable(s). Consequently, relying solely on the regression analysis to make accurate predictions or draw conclusions may be unreliable.

It is important to interpret the results cautiously and consider alternative explanations or additional variables that might contribute to the observed variability in the data. Further exploration and analysis may be needed to identify other potential factors that influence the relationship between the variables and to determine whether a different model or approach is more appropriate.

The population density of Philadelphia is approximately 11,761.76 people per square mile, while the population density of Pottstown is approximately 4,672.16 people per square mile.

To compare the densities of Philadelphia and Pottstown, we need to calculate the population density for each city. Population density is typically measured as the number of individuals per unit area.

For Philadelphia:

Population = 1,579,000

Land area = 134.28 sq miles

Population density = Population / Land area

Population density = 1,579,000 / 134.28

Population density \(^\sim_\sim\) 11,761.76 people per square mile

For Pottstown:

Population = 22,670

Land area = 4.85 sq miles

Population density = Population / Land area

Population density = 22,670 / 4.85

Population density \(^\sim_\sim\) 4,672.16 people per square mile

Therefore, the population density of Philadelphia is approximately 11,761.76 people per square mile, while the population density of Pottstown is approximately 4,672.16 people per square mile.

Comparing the two, we can see that Philadelphia has a higher population density compared to Pottstown.

The another equivalent expression of total liquid is (x+2)/4.

Expressions that perform similarly but differ in appearance are said to be equivalent expressions. When the same value for the variable is entered, two algebraic expressions that are equivalent will have the same result.

x quarts liquid in the container 3/4 part of liquid is removed

Then remaining liquid in container = X - \(\frac{3}{4}X\)

Then remaining liquid in container = x/4quarts

Another 1/2 quart is poured into container

Then total liquid = \(X-\frac{3}{4}X+\frac{1}{2}\) quarts

total liquid = \(\frac{X+2}{4}\) quarts

A, B, F

Step-by-step explanation:

To solve this, you look at the powers of x and take either the square root (if it is to a power of 2) or the cube root (if a power of 3) of both sides to isolate x. For the first equation, you take the square root of 48, so A is correct. For the second one, you take the square root of 63, so B is correct. For the final equation, you take the cube root of 73, so F is correct.

The standard deviation of the number of defective bulbs in a sample of 11 light bulbs, where 60% are defective, is 1.53, rounded to two decimal places.

The number of defective bulbs in a sample of 11 light bulbs follows a binomial distribution with parameters n = 11 and p = 0.6, where n is the sample size and p is the probability of a defective bulb.

The standard deviation of the binomial distribution is given by the formula:

σ = sqrt(np(1-p))

where σ is the standard deviation, n is the sample size, p is the probability of success (defective bulb), and (1-p) is the probability of failure (non-defective bulb).

Substituting the values into the formula, we get:

σ = sqrt(11 * 0.6 * 0.4) = 1.53

Therefore, the standard deviation of the number of defective bulbs in the sample is 1.53, rounded to two decimal places.
