A rectangle's length is 5 inches greater than its width. if the perimeter of the rectangle is 42 inches, then the length is 13 inch.

A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.

here, we have,

a rectangle's length is 5 inches greater than its width.

if the perimeter of the rectangle is 42 inches

let, width = x

then, length = x+5

so, perimeter= 2(x+5 +x)

                      = 4x+10

ATQ, 4x+10 = 42

solving we get,

x=8

the length = 13

Hence, A rectangle's length is 5 inches greater than its width. if the perimeter of the rectangle is 42 inches, then the length is 13 inch.

Step-by-step explanation:

7 fishes οf the new released initially in the given expοnential pοpulatiοn grοwth. (οptiοn c)

Expοnential pοpulatiοn grοwth means that whatever the pοpulatiοn size is, it keeps increasing because the pοpulatiοn per individual remains the same, accelerating pοpulatiοn grοwth that is limited by limited resοurces. Hence, this increase in pοpulatiοn size is knοwn as expοnential pοpulatiοn grοwth.

The grοwth οf their pοpulatiοn is mοdeled by the expοnential functiοn

P(t)=\(7b^{t}\) ,where t is the time in weeks after the release and b is a pοsitive unknοwn base.

Initially that is t=0

sο fοr t=0,

p(0)=7×1 [since sοmething tο the pοwer zerο is equal tο 1]

Hence, P(0)=7

Number of strings of seven hexadecimal digits that do not have any repeated digits and at least one repeated are required. The hexadecimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

Number of strings of seven hexadecimal digits that do not have any repeated digits. There are sixteen different digits.The first digit can be any one of the sixteen different digits. Hence, the first digit can be chosen in 16 ways. Once the first digit has been chosen, there are only fifteen remaining digits. Hence, the second digit can be chosen in 15 ways. Similarly, the third digit can be chosen in 14 ways, the fourth digit can be chosen in 13 ways, and so on. Thus, the number of ways that a string of seven hexadecimal digits can be formed without any repeated digits is given by 16×15×14×13×12×11×10 = 111, 767, 040

Number of strings of seven hexadecimal digits that have at least one repeated digit is required. There are two ways to approach the solution of this problem:By finding the number of strings that do not have any repeated digits and subtracting this from the total number of strings of seven hexadecimal digits.By counting the number of strings that have at least one repeated digit directly.

Method 1 : To find the number of strings that do not have any repeated digits, we have found in part (a) to be 111, 767, 040. The total number of strings of seven hexadecimal digits is 167, 772, 160. Hence, the number of strings of seven hexadecimal digits that have at least one repeated digit is given by:167, 772, 160 – 111, 767, 040 = 56, 005, 120

Method 2 :By counting the number of strings that have at least one repeated digit directly, we shall apply the principle of inclusion and exclusion. Let A1, A2, A3, A4, A5, A6, A7 denote the events that the first, second, third, fourth, fifth, sixth and seventh digits repeat, respectively. The number of strings in which only the first and second digits repeat is 16×15×14×13×12×11×1 = 24,883,200. Similarly, the number of strings in which only the first and third digits repeat is 24, 883, 200. There are fifteen possible pairs of distinct digits and for each such pair, there are 10 ways to place the two digits into the seven positions, i.e., ten different arrangements of the pair of digits. Hence, the number of strings in which exactly two digits repeat is given by 15×10×16×15×14×13×1 = 56,160,000. There are six different ways in which three distinct digits can be selected from sixteen. For each choice of three distinct digits, there are three possible ways that the digits can be arranged in the string. This gives a total of six×3×16×15×14×1×1×1 = 60,480. There are no strings with four or more distinct digits repeating. Thus, by the principle of inclusion and exclusion, the number of strings of seven hexadecimal digits with at least one repeated digit is given by24, 883, 200+24, 883, 200−56, 160, 000+60, 480=56,005,120

The number of strings of seven hexadecimal digits that do not have any repeated digits is 111, 767, 040. The number of strings of seven hexadecimal digits that have at least one repeated digit is 56, 005, 120.

Answer:

15 \(\frac{1}{2}\)

Step-by-step explanation:

30 - (9 \(\frac{9}{10}\) + 4 \(\frac{3}{5})\)  I need a common denominator.  I could use lots of different numbers, but 10 would be the easiest.  

\(\frac{3}{5}\) x \(\frac{2}{2}\) = \(\frac{6}{10}\)

30 - (9\(\frac{9}{10}\) + 4 \(\frac{6}{10}\))

30 - 13 \(\frac{15}{10}\)

13 \(\frac{15}{10}\) is the same as 13 + \(\frac{10}{10}\) + \(\frac{5}{10}\) = 13 + 1 + \(\frac{5}{10}\) = 14 \(\frac{5}{10}\)

30 - 14 \(\frac{5}{10}\)

29 \(\frac{10}{10}\) - 14 \(\frac{5}{10}\) = 15 \(\frac{5}{10}\)

\(\frac{5}{10}\) ÷\(\frac{5}{5}\) = \(\frac{1}{2}\)

15 \(\frac{1}{2}\)

The height of the tree to the nearest foot is 75.

Step-by-step explanation:

The height is opposite the angle of elevation, and the 45 ft distance to the tree is adjacent to it.

tangent = opposite/adjacent

\(\frac{tan(59)}{1} = \frac{h}{45}\)

h = tan(59) * 45

h ≈ 74.89

To the nearest foot, 74.89 is 75 ft.

Angle ∠C and angle ∠E are supplementary angles. Then the correct option is B.

The sum of the supplementary angle is 180 degrees.

The sum of two acute angles will be less than 180 degrees.

Similarly, the sum of two obtuse angles is more than 180 degrees.

The addition of angle ∠C and angle ∠E is calculated as,

∠C + ∠E = 61° + 119°

∠C + ∠E = 180°

The addition of angle ∠C and angle ∠E is 180°. Thus, the correct option is B.

The population mean age of the winners of the award for the past five years is 42 years.

To compute the population mean, we add up all the values in the data set and divide the sum by the total number of values in the population.

In this case, the population consists of the ages of the winners of an award for the past five years, and there are five values in the data set: 42, 42, 55, 28, and 43.

So, the population mean is:

(42 + 42 + 55 + 28 + 43) / 5 = 210 / 5 = 42

Therefore, the population mean age of the winners of the award for the past five years is 42 years.

X < 10  
where X is the weight of the package in pounds

The package should weigh less than 10 pounds for Ship4U to be the cheaper option

Step-by-step explanation

Let the weight of the package be X pounds

Cost of shipping by Post Office = 9 + 0.5X

Cost of shipping by Ship4U = 6 + 0.8X

For Ship4U to be the cheaper option
6 + 0.8X < 9 + 0.5X

Subtract 6 on both sides and subtract 0.5X from both sides:
0.8X - 0.5X < 9 - 6
0.3X < 3

Divide by 0.3 on both sides
0.3X/0.3 < 3/0.3

X < 10

The package should weigh less than 10 pounds for Ship4U to be the cheaper option

At a weight of 10 pounds, both shipping costs are the same
Post Office cost for 10lb package = 9 + 0.5(10) = 9 + 5 = $14
Ship4U cost for 10lb package = 6 + 0.8(10) = 6 + 8 = $14

Linear equations involve equalities (i.e., "=") and are used to represent lines in a coordinate plane. Linear inequalities, on the other hand, involve inequalities (i.e., "<", ">", "<=", ">=") and are used to represent regions or areas of a coordinate plane that satisfy certain conditions.

A linear equation can be expressed in the form "y = mx + b," where "m" represents the slope of the line and "b" represents the y-intercept. Given the values of "m" and "b," you can calculate the y-coordinate for any given x-coordinate, and vice versa. The graph of a linear equation is a straight line.

A linear inequality is expressed in the form "y < mx + b," "y > mx + b," "y <= mx + b," or "y >= mx + b." Instead of representing a single line, a linear inequality represents a shaded region on the coordinate plane that satisfies the given condition. To graph a linear inequality, you can choose a test point not on the line and check whether it satisfies the inequality. If it does, shade the region containing the test point; otherwise, shade the other region.

In summary, the main difference between linear equations and linear inequalities is the use of equalities versus inequalities. Linear equations represent lines, while linear inequalities represent shaded regions on the coordinate plane. Equations deal with exact solutions, whereas inequalities deal with a range of possible solutions. Understanding the distinctions between these concepts is important in various areas of mathematics, such as algebra and geometry.

The average of y is given x in the simple regression model. The correct answer is OC. Hyjx = Bo +Byx.

A regression model is a statistical method for estimating the relationship between one or more independent variables and a dependent variable (also known as the response variable) (also called the explanatory variables or predictors). The primary goal of regression analysis is to forecast the value of the dependent variable based on the independent variables' values.

In a simple linear regression model, the equation is y = Bo + B1x + e, where Bo is the intercept and B1 is the slope. The average of y given x is represented by the expected value of y given x, which is E(y|x) = Bo + B1x. This equation represents the regression line, which is a line that best fits the data points in the scatter plot.

f(x)= -2x + 1

Step-by-step explanation:

The function we will find is to be written in slope-intercept form, which is y=mx+b.

One way to find the answer would be by graphing the function, wich you can do on an online calculator or a sheet of paper.

Another way to get to our answer without even having to graph is by finding the y-intercept, or the b, of the function given in the table.

We can do this by looking at the 0 value of the table. The table tells us that the y-intercept is 1.

So, we have to look at our options and see which one has +1 for the y-intercept.

The option f(x)=-2x+1 is the answer

How to check your work: input the given x values into the chosen function, in this case f(x)= -2x + 1
