The perimeter of the rectangle shown below is 52 inches. The perimeter of the triangle shown below is 40 inches.

Answer: Yes

Step-by-step explanation:

To determine if Mindy's estimate is reasonable, we need to consider the context of the movie theater and the audience it serves. Generally, movie theaters offer tickets to various categories of customers, such as adults, children, and seniors. Seniors usually receive discounted tickets to encourage their attendance.

Mindy estimates that out of 400 tickets sold on a Friday evening, about 100 of them will be senior tickets. This means that she is estimating that 25% of the tickets sold are senior tickets (100 senior tickets / 400 total tickets = 0.25 or 25%).

While it's difficult to know the exact proportions of ticket categories sold without more information, a 25% estimate for senior tickets may be reasonable if the movie theater attracts a diverse audience and offers films or events that appeal to seniors. The actual proportion of senior tickets might vary depending on the location of the theater, the movies being shown, and the demographics of the surrounding community.

It would be helpful to gather more data on the actual distribution of ticket sales across different categories or to compare Mindy's estimate with industry averages to determine if her estimate is reasonable.

Consider concert tickets as a long-term savings objective.Therefore, the answer is A.

Savings refers to anything that existing at any given moment, a stock variable, whereas saving refers to an action occurring over period, a flow variable. Even seasoned economists and financial experts frequently refer to "saving" for "savings" due to the widespread misunderstanding of this distinction.\

Saving for a concert is not a long-term savings goal because it is a short-term financial goal. Long-term savings goals typically involve saving money for events or expenses that will occur several years or even decades in the future, such as college, a down payment on a house, or retirement. Saving for a concert is unlikely to take more than a few months or a year, so it is not a long-term goal.

Using division, we can find that he must sell 2123 pairs to get a profit of $69840.

One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.

Here,

Profit by selling one pair of shoes = $80.

Now, expenses = $100,000

Total profit he wants = $69,840.

So, total revenue to be generated = 100000 + 69840

= $169840.

Let x be the total pairs sold.

So, x = 169840/80

= 2123.

Therefore, he must sell 2123 pairs to get a profit of $69840.

Since the outputs of -5 and 1, and -1 and 7, are not equal, we can conclude that f is injective.

In mathematics, a function is a rule that assigns a unique output value to each input value in a given set. The input values are also known as the domain of the function, while the output values are known as the range. A function can be thought of as a machine that takes an input and produces an output. For example, a simple function could be doubling a number. In this case, the input is the number to be doubled, and the output is the result of doubling that number.

Here,

To determine if a function is injective, we need to check whether different inputs produce different outputs. In other words, if for any two distinct inputs x and y, f(x) is not equal to f(y), then the function is injective.

Let's examine the table of values for the function f:

× -5 -3 -1 0 3 5

f(×) 1 3 7 3 2 4

We can see that f(-5) = 1, f(-3) = 3, f(-1) = 7, f(0) = 3, f(3) = 2, and f(5) = 4.

Since the outputs of -5 and 1, and -1 and 7, are not equal, we can conclude that f is injective. Therefore, for this function, no two distinct inputs produce the same output.

Answer:

perimeter = 96.8 m

Step-by-step explanation:

the sides of a square are congruent , then perimeter (P) is calculated as

P = 4s ( s is the side length )

the area (A ) of a square is calculated as

A = s²

given A = 585.64 , then

s² = 585.64 ( take square root of both sides )

s = [tex]\sqrt{585.64}[/tex] = 24.2

Then

P = 4 × 24.2 = 96.8 m

Answer:

= 96.8 m

Step-by-step explanation:

Area of a square = side²

Perimter of a square = 4*side

Then:

585.64 = side²

√585,64 = √side²

it is a geometric figure, therefore, only the positive value will be obtained

24.2m = side

Perimeter = 4*side

Perimeter = 4*24.2

Answer:

Step-by-step explanation:

they are adjacent because they are next to each other

We are given the system of equations:

p = d + 3 ----(1)

p + 2d = 10.50 ----(2)

We can use substitution to solve for the variables. From equation (1), we can see that p = d + 3. We can substitute this expression for p in equation (2) to get:

(d + 3) + 2d = 10.50

Simplifying this equation, we get:

3d + 3 = 10.50

Subtracting 3 from both sides, we get:

3d = 7.50

Dividing both sides by 3, we get:

d = 2.50

Now that we know the value of d, we can substitute this back into equation (1) to solve for p:

p = d + 3

p = 2.50 + 3

p = 5.50

Therefore, the solution to the system is p = 5.50 and d = 2.50.

Step-by-step explanation:

If the original figure has a height of 25 inches and it was photocopied at a scale of 40%, we can find the new height of the figure by multiplying the original height by the scale factor:

new height = 25 inches x 0.4

new height = 10 inches

Therefore, the new height of the figure is 10 inches.

Answer:

Wassup

Step-by-step explanation:

By multiplying the initial height by the scale factor, which is 40% or 0.4 in decimal notation, the new height of the image can be calculated.

New height: 25 inches times 0.4 to equal 10 inches.

The figure's revised height is 10 inches as a result.

(a) The standard error of the mean is 129. (b) The probability that the sample mean will be more than $27,175 is 0.50 (c) The probability that the sample mean will be within $1,000 of the population mean is 0.955. (d) The probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100 is 0.999.

(a) The standard error of the mean is the square root of the population standard deviation divided by the sample size, which in this case is 7,400/57 = 129.12. The value of the standard error of the mean is therefore 129 (rounded to the nearest whole number).

(b) To find the probability that the sample mean will be more than $27,175, you can use the Z-score formula. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175)/129 = 0. The probability that the sample mean will be more than $27,175 is 50%, since the probability of any Z-score of 0 is 0.50.

(c) To find the probability that the sample mean will be within $1,000 of the population mean, you can use the Z-score formula again. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175±1000)/129 = ±7.8. The probability that the sample mean will be within $1,000 of the population mean is 95.5%, since the probability of any Z-score of ±7.8 is 0.955.

(d) To find the probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100, you can use the Z-score formula again. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175±1000)/74 = ±13.5. The probability that the sample mean will be within $1,000 of the population mean is 99.9%, since the probability of any Z-score of ±13.5 is 0.999.

Total surface area includes a square base and four triangular faces and the measure of it is:

The matching choice is B.

Answer:

length = 10 in

width = 8 in

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Then:

36 = 2(h + w)          Eq. 1

h = 2 + w                 Eq. 2

h = length

w = width

From Eq. 1

36/2 = h + w

18 = h + w              Eq. 3

Replacing Eq. 2 in Eq. 3

18 = (2+w) + w

18 = 2 + 2w

18 - 2 = 2w

16 = 2w

16/2 = w

w = 8

From Eq. 2

h = 2 + w

h = 2 + 8

h = 10

Check:

from Eq. 1:

36 = 2(h + w)

36 = 2(10 + 8)

36 = 2*18

The new number that was added to the set is 74 by using mean formula for some numbers.

Let's begin by determining the mean of a set of numbers using the following formula:

average = (sum of numbers) / (number of numbers)

We can write: since we know that the mean of 21 numbers is 30.

/ 21 = 30 = (sum of 21 numbers)

Multiply LHS and RHS by woth 10:

sum of 21 digits equals 630

The new mean will now be determined by adding a new number to the set. Let's call the new number x since we don't yet know its value. We can write: 32 = (sum of 21 numbers + x) / 22 since we also know the new mean is 32.

The result of adding the two sides together is: total of the 21 numbers plus x = 704

We may change the equation to read 630 + x = 704 as we already know the sum of the original 21 values is 630.

630 is subtracted from both sides, giving us:

x = 74

74 is the new number that was so added to the collection.

The graph of each function from a to d are attached below

Graphs of nonlinear functions are graphs of functions that do not have a constant rate of change or a linear relationship between the input and output values. Nonlinear functions include quadratic, exponential, logarithmic, trigonometric, and many other types of functions.

The shape of the graph of a nonlinear function can vary greatly depending on the specific type of function. For example:

The graph of a quadratic function (y = ax^2 + bx + c) is a parabola, which is a symmetric U-shaped curve.

The graph of an exponential function (y = a^x) is a curve that increases or decreases rapidly, depending on whether the base a is greater than or less than 1.

The graph of a logarithmic function (y = log_a(x)) is a curve that approaches a vertical asymptote as x approaches zero.

The graph of a trigonometric function (y = sin(x) or y = cos(x)) is a periodic wave that oscillates between a maximum and minimum value.

Nonlinear functions can exhibit complex and interesting behaviors, such as multiple intercepts, asymptotes, and singularities. The graphs of these functions can be used to model a wide range of real-world phenomena, such as population growth, radioactive decay, and the motion of objects under the influence of gravity.

The constant percent rate of change in the exponential function [tex]f(x) = 2(3)^x[/tex] is 200%, indicating a doubling of the output value for each unit increase in the input value.

The equation [tex]f(x) = 2(3)^x[/tex] represents an exponential function. Exponential functions have a constant percent rate of change, which means that the percent change between any two points on the graph of the function is the same.

In this case, we can find the percent rate of change by calculating the ratio of the output values for any two input values that differ by 1. For example, if we compare the output value when x=1 to the output value when x=0, we get:

[tex]f(1) = 2(3)^1 = 6[/tex]

[tex]f(0) = 2(3)^0 = 2[/tex]

The percent change from x=0 to x=1 is:

percent change = (f(1) - f(0)) / f(0) x 100%

= (6 - 2) / 2 x 100%

= 200%

This means that the output value increased by 200% when the input value increased by 1. We can also express this as a constant percent rate of change by dividing the percent change by the change in input value:

constant percent rate of change = percent change / change in input value

= 200% / 1

= 200%

Therefore, the equation [tex]f(x) = 2(3)^x[/tex] has a constant percent rate of change of 200%.
