Step-by-step explanation:

x = cost of 13 glue sticks

4 glue sticks cost $7.76, so to find the cost of 13 glue sticks, you would use the equation:

x = (13/4) * $7.76

or

x = $20.40

The coordinate of the point that represents the number of pens that Keisha buys and the total cost is (2, 4)

The given parameters are

Number of pen = 2

Unit price = $2

This means that the total amount spent is

Total amount = Number of pen * Unit price

Evaluate the product

Total amount = 2 * 2

Evaluate the product

Total amount = 4

So, the coordinate of the point that represents the number of pens that Keisha buys and the total cost is (2, 4)

The area of Rowniel's expanded tulip section is 312 square feet.

To find the area of Rowniel's expanded tulip section, we first need to determine the dimensions of the expanded section.

The original tulip section has a length of 10 feet and a width of 24 feet. If Rowniel increases the length and width of each section by 2 feet, the expanded tulip section will have a length of 10 + 2 = 12 feet and a width of 24 + 2 = 26 feet.

To calculate the area of the expanded tulip section, we multiply the length by the width:

Area = Length × Width

Area = 12 feet × 26 feet

Area = 312 square feet

Therefore, the area of Rowniel's expanded tulip section is 312 square feet.

In this problem, a researcher wants to estimate the number of households with two cars with 95% confidence and a margin of error of 5%. The researcher also knows that a previous study showed that 22% of households had two cars. The possible answers are 4, 339, and 186.

To answer this question, we need to use the formula for sample size calculation: n = (Z^2 * p * q) / E^2, where n is the sample size, Z is the Z-score for the desired level of confidence (in this case, 1.96 for 95% confidence), p is the estimated proportion of the population with the characteristic of interest (in this case, 0.22), q is the complement of p (q = 1 - p), and E is the desired margin of error (in this case, 0.05). Plugging in these values gives us n = (1.96^2 * 0.22 * 0.78) / 0.05^2, which simplifies to n = 186.

Therefore, the correct answer is (c) 186. This means that the researcher needs to survey 186 households to estimate the number of households with two cars with 95% confidence and a margin of error of 5%.

A linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form can be solved.

A mathematical representation of a system based on the application of a linear operator is known as a "linear system" in systems theory. Ordinarily, compared to nonlinear systems, linear systems display much simpler features and properties. The automatic control theory, signal processing, and telecommunications all heavily rely on linear systems as a mathematical abstraction or idealisation.

Linear systems, for instance, are frequently used to model the propagation medium for wireless communication systems. An operator, H, that converts an input, x(t), into an output, y(t), a kind of black box description, can be used to describe a general deterministic system.

The superposition principle, or alternatively both the additivity and homogeneity properties, must be satisfied by a system to be considered linear, and only then.

Answer:

243 cm³

Step-by-step explanation:

A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that

Length x width = 9 square centimeters

But, since length and width are the same, we have that they are equal to \(\sqrt{9} =3\) cms (since 3² = 9).

Thus, the volume of each cube is 3³ = 27 cm³

We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.

Volume of prism = 9 (27) = 243 cm³

The first five terms of the recursive sequence are 4.5, -27, 162, -972 and 5832

From the question, we have the following parameters that can be used in our computation:

an = -6a(n - 1)

a1 = -4.5

The above definitions imply that we simply multiply -6 to the previous term to get the current term

Using the above as a guide,

So, we have the following representation

a(2) = -6 * 4.5 = -27

a(3) = -6 * -27 = 162

a(4) = -6 * 162 = -972

a(5) = -6 * -972 = 5832

Hence, the first five terms of the recursive sequence are 4.5, -27, 162, -972 and 5832

The probability of the interval -1.62 < z < 2.01 in a standard normal distribution is approximately 0.9262 or 92.62%.

In a standard normal distribution, the mean is 0 and the standard deviation is 1. The z-score represents the number of standard deviations a data point is from the mean. To find the probability of a specific interval, we calculate the area under the curve between the corresponding z-values.

Given the interval -1.62 < z < 2.01, we need to find the area under the standard normal curve between these two z-values. This can be done using a standard normal distribution table or by using a statistical software or calculator.

By looking up the z-values in the table or using software, we find the corresponding probabilities: P(z < -1.62) = 0.0526 and P(z < 2.01) = 0.9788.

To find the probability of the interval -1.62 < z < 2.01, we subtract the probability of the lower bound from the probability of the upper bound: P(-1.62 < z < 2.01) = P(z < 2.01) - P(z < -1.62 = 0.9788 - 0.0526 = 0.9262.

Answer:

y = -1/5x + 6

Step-by-step explanation:

First rearrange x + 5y = 10 into y = mx + b format.

x + 5y = 10

5y = -x +10

y = -1/5x + 2

If a line is parallel to y = -1/5x + 2, it must have the same slope (-1/5).

Plug in for y = mx + b

x (x coordinate) = -5

y (y coordinate) = 7

m (slope) = -1/5

Solve for b.

7 = -5(-1/5) + b

7 = 1 + b

b = 6

y = -1/5x + 6 is parallel.

The amount after 5 years with a simple interest of 5 % is A = $ 875

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the amount in the bank after 5 years be A

Let the simple interest be represented as I

Now , the principal amount invested = $ 700

The rate of interest r = 5 %

The number of years n = 5 years

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

On simplifying , we get

Simple Interest I = ( 700 x 5 x 5 ) / 100

Simple Interest I = 25 x 7

Simple Interest I = $ 175

Now , the amount after 5 years = P + I = 700 + 175

The amount after 5 years = $ 875

Hence , the amount after 5 years in the bank is $ 875

The best measure to compare the variability of two arrival processes is the coefficient of variation (CV).

The coefficient of variation (CV) is the ratio of the standard deviation to the mean of a dataset and is a dimensionless quantity. It provides a relative measure of variability that takes into account the scale of the data. When comparing the variability of two arrival processes, it is important to consider both the spread (standard deviation) and the central tendency (mean) of the data. The CV allows for a standardized comparison by normalizing the standard deviation with respect to the mean.

Using the standard deviation alone (option a) does not take into account the differences in means and can be misleading when comparing arrival processes with different average values. The range (option b) is a simple measure of spread but does not consider the scale or central tendency of the data, making it less suitable for comparing variability. Similarly, the mean (option c) provides information about central tendency but does not account for the spread. Therefore, the coefficient of variation (option d) is the most appropriate measure as it combines information about both the mean and the standard deviation, allowing for a meaningful comparison of variability between two arrival processes.
