Step-by-step explanation:
There are a total of 6 sides
two are 3 x 6 m^2
two are 3x 5 m^2
two are 6 x 5 m^2
Area = 2 ( 3x6 + 3x5 + 6x5) = 126 m^2
Let’s start with the top and bottom, which can be found by 2(L • W), because there are two sides:
A = 2(L • W)
A = 2((3)(6))
A = 36 m^2
Now let’s get the front and back using
2(W • H):
A = 2(W • H)
A = 2((6)(5))
A = 60 m^2
Finally, lets get the twi sides using
2(L • H):
A = 2(L • H)
A = 2((3)(5))
A = 30 m^2
Now add up these areas for the total surface area:
36 + 60 + 30 = 126 m^2

Answers
Therefore, the answer is option 4: a reflection over the line y=-x-6.
What is transformation?In mathematics, a transformation is a process that changes the position, size, or shape of a geometric object in some way. Transformations are often used in geometry and other branches of mathematics to study the properties of shapes and their relationships to each other.
Here,
To determine which transformation carries the rhombus onto itself, we need to identify the symmetries of the rhombus. A rhombus has two types of symmetry: rotational symmetry and reflectional symmetry.
Option 1: a rotation of 180 degrees clockwise about (-2,-2)
This transformation takes each point of the rhombus and rotates it 180 degrees clockwise about the point (-2,-2). Since the rhombus has rotational symmetry of order 2 (i.e., a rotation of 180 degrees carries the rhombus onto itself), this transformation carries the rhombus onto itself.
Option 2: a rotation of 90 degrees counterclockwise about (-2,-2)
This transformation takes each point of the rhombus and rotates it 90 degrees counterclockwise about the point (-2,-2). Since the rhombus does not have rotational symmetry of order 4 (i.e., a rotation of 90 degrees does not carry the rhombus onto itself), this transformation does not carry the rhombus onto itself.
Option 3: a reflection over the line y=x+10
This transformation reflects each point of the rhombus over the line y=x+10. Since the rhombus does not have reflectional symmetry over this line, this transformation does not carry the rhombus onto itself.
Option 4: a reflection over the line y=-x-6
This transformation reflects each point of the rhombus over the line y=-x-6. Since the rhombus has reflectional symmetry over this line, this transformation carries the rhombus onto itself.

Answers
The approximate value of the home in 1987 is approximately $161,872.
The formula to calculate the approximate value of a home in 1987 is:
V1987 = 81600 x (1 + 0.12)^7
V1987 = 81600 x 1.987
V1987 = 161872
Therefore, the approximate value of the home in 1987 is approximately 161,872.
To arrive at this answer, we first started with the value of the home in 1980, which was 81,600. We then multiplied this value by 1.12, which is the 12% increase every year, to the seventh power. This resulted in a value of 1.987. We then multiplied this value by the original value of the home in 1980, which gave us the approximate value of the home in 1987. We then rounded the answer to the nearest hundred dollars, which resulted in the answer of 161,872.

The value of a brand new car is $10,000 and the value depreciates 18% every year. Write a function to represent the value of the car after t years, where the quarterly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per quarter, to the nearest hundredth of a percent.
Answers
The function representing the value of car is 10000 (1 - 0.045)[tex]^{(4t)}[/tex]. The percentage rate of change per quarter is 0.68%. The solution has been obtained by using the substitution method.
What is the substitution method?
The substitution approach is a widely used method in algebra for solving simultaneous linear equations. The name of the method implies that the value of one variable from one equation is changed in the second equation.
We are given that the value of car depreciates 18% every year.
Let f(t) represent the car's worth after t years.
So, we get the function as:
⇒ f(t) = 10000 (1 - 0.18/4)[tex]^{(4t)}[/tex]
⇒ f(t) = 10000 (1 - 0.045)[tex]^{(4t)}[/tex]
Now, the percentage rate of change per quarter is:
⇒ r = [tex](1-q)^{4}[/tex] - 1
Here, q = 0.045
On substituting the value, we get
⇒ r = [tex](1-0.045)^{4}[/tex] - 1
⇒ r = -0.68%
Hence, the required solutions have been obtained.

Do the values in the table represent a linear function? if so what is the function rule?
Answers
The values in the table represent a linear function with the function rule y = 3x + 6, where x is the input value and y is the output value.
To determine if the values in the table represent a linear function, we can check if there is a constant rate of change between the input and output values. This means that for every increase or decrease in the input value, there is a constant increase or decrease in the output value.
Looking at the input and output values in the table, we can see that for every increase of 1 in the input value, the output value increases by 3. This constant rate of change indicates that the values in the table represent a linear function.
To find the function rule, we can use the slope-intercept form of the equation for a linear function, which is y = mx + b, where m is the slope and b is the y-intercept. In this case, we can find the slope by dividing the change in output values by the change in input values:
slope = change in output / change in input = 3/1 = 3
Therefore, the slope of the function is 3. To find the y-intercept, we can use one of the points in the table. For example, we can use the first row, which gives an input value of 0 and an output value of 6:
y = mx + b
6 = 3(0) + b
b = 6
Therefore, the y-intercept of the function is 6. Combining the slope and y-intercept, we can write the function rule as:
y = 3x + 6
This means that for any input value x, the output value y is equal to three times x plus six.

A survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements?
Answers
After answering the provided question, we can conclude that As a result, normal distribution the new height requirement for women to join this branch of the military is 57.1 inches to 68.6 inches.
what is normal distribution?The normal distribution is an example of a constant distribution of probabilities, in which the majority of the points cluster near the range's center and the ones that are left decrease symmetrically towards one of the extremes. The mean of the spread is another term for the range's centre. According to the bell curve, also known as the Distribution function, which is symmetrical well about mean, data that are near the median are more frequent than data that are far from the mean. I'm using heuristics in normality to obtain a child's SAT scores from an innovative exam prep course. The data have a normal distribution with a mean (M) of 1150 and a standard deviation (SD) of 150.
a. To calculate the percentage of women who meet the height requirement, find the area under the normal distribution curve between 58 and 80 inches.
For x = 58 inches: z = (58 - 63.4) / 2.5 = -2.16
For x = 80 inches: z = (80 - 63.4) / 2.5 = 6.64
This means that all women with heights ranging from 58 to 80 inches meet the requirement.
b. For the shortest 1%, we need to find the height that corresponds to z = -2.33:
-2.33 = (x - 63.4) / 2.5
x = 57.1 inches
So the new minimum height requirement is 57.1 inches.
For the tallest 2%, we need to find the height that corresponds to z = 2.05:
2.05 = (x - 63.4) / 2.5
x = 68.6 inches
So the new maximum height requirement is 68.6 inches.
As a result, the new height requirement for women to join this branch of the military is 57.1 inches to 68.6 inches.

Answers
When Frederick purchases a cup of coffee, he gets handed €1.65 in change rather than the expected €1.50. The error percentage is 9.09%
Explain about the percentage error?The variation between the real value and the predicted value, in relation to the theoretical value, is known as percentage error.
When compared to the real number and expressed in percent format, percentage error seems to be the gap between the anticipated amount and the actual number. The equation is as follows:
To put it another way, you divide the deviation between the true answer and the answer you guessed by the true answer to get the percent.
Amount paid by Fredrick for cup of coffee: €1.65

Applying the linear pair theorem, the measures of the angles in degrees are:
m<ABD = 112°; m<DBC = 68°
What is the Linear Pair Theorem?The Linear Pair Theorem, also known as the Linear Pair Postulate, is a basic postulate in geometry that describes the relationship between two adjacent angles that form a straight line.
According to the Linear Pair Theorem, if two angles are adjacent and form a straight line, then they are supplementary. In other words, their measures add up to 180 degrees.
Therefore, according to the linear pair theorem, we have:
m<ABD + m<DBC = 180°
Substitute:
7x + 196 + 9x + 176 = 180
16x + 372 = 180
16x = 180 - 372
16x = -192
x = -192/16
x = -12

meghan, a researcher at um, conducted a similar survey among michigan residents. she used a random sample of the same size as the study conducted by the pew research center and obtained the same value for the sample proportion. gloria is concerned that the computation of the margin of error for a confidence interval for the population proportion will be affected by the fact that the population size for all michigan residents is much smaller than that for all us adults. do you agree with gloria's concern?
Answers
Yes, Gloria's concern about the computation of the margin of error for a confidence interval for the population proportion being affected by the fact that the population size for all Michigan residents is much smaller than that for all US adults is true.
Sample
A subset of the population is known as a sample. A sample is a smaller group of individuals or things chosen from the population.
Error
The distinction between the estimated value of a population parameter and the true, but unknown, value of that parameter is referred to as an error. Sampling error is the difference between the sample statistic and the population parameter. Inference is less accurate if the sample is too small or if the sample is biased, and the resulting sample statistics may differ from the actual population parameters.
Hence, from the above, we can conclude that yes the Gloria's concern about the computation of the margin of error for a confidence interval for the population proportion being affected by the fact that the population size for all Michigan residents is much smaller than that for all US adults is true.

B A'(4, 4), B'(6, 4), C'(6, 5)A'(4, 4), B'(6, 4), C'(6, 5)
C A'(4, 4), B'(8, 4), C'(8, 6)A'(4, 4), B'(8, 4), C'(8, 6)
D A'(1, 1), B'(2, 1), C'(2, 32
Answers
The vertices after the dilation arE:
C A'(4, 4), B'(8, 4), C'(8, 6)
Which are the vertices after the dilation?The original vertices are A(2, 2), B(4, 2), and C(4, 3). And we apply a dilation of scale factor 2, then to get the new coordinates ust multiply all the coordinates by 2, we will get.
A' = (2*2, 2*2) = (4, 4)
B' = (4*2, 2*2) = (8, 4)
C' = (4*2, 3*2) = (8,6)
Then the correct option in this case is:
C A'(4, 4), B'(8, 4), C'(8, 6)

school ski trip each winter the pta organizes a ski trip students pay a upfront cost cost which includes a 2 night stay transportation meals and 6 hours of skiing each day this
*this year the PTA has 7 chaperones going on the trip and each chaperone will supervise exactly 15 students
*the PTA collected $25,515 from the students to pay for the trip
*the chaperones pay for their own hotel rooms but the PTA pays for the hotel rooms for the students. each room can hold 4 students
*students and chaperones take the school buses from the school to the ski resort. each bus seat 48 people
*students can choose to go snow tubing during the trip but this is not included in the cost of the trip the cost for tubing is $23 for the lift ticket plus the cost of renting specialty snow boots the total cost of snow tubing is 29
use this information to write and solve equations to determine the number of students going on the trip the cost per student, the number of hotel rooms needed for the students,the number of buses needed, and the cost to rent snow boots for turbing
your work should include:
defined variables(2 points)

Answers
The number of students going on the trip is 105 students. The cost per student is $ 243 per student. The number of hotel rooms needed is 27 hotel rooms.
The number of buses needed is 3 buses. The cost to rent snow boots for turbing is $ 6.
How to find the number of students?Let's define the variables:
s = number of students going on the trip
c = cost per student
h = number of hotel rooms needed for the students
b = number of buses needed
r = cost to rent snow boots for tubing
The equations would then be:
s = 7 chaperones × 15 students/chaperone
$25,515 = s × c
h = ceil (s / 4)
b = ceil ((s + 7) / 48)
$29 = $23 + r
Solving the equations then gives:
Number of students on trip:
s = 7 × 15 = 105 students
Cost per student :
$25,515 = 105 × c
c = $25,515 / 105
= $243 per student
Number of hotel rooms :
ceil(105 / 4) = 27 hotel rooms
Number of buses :
= ceil((105 + 7) / 48)
= ceil(112 / 48)
= 3 buses
Cost per student for snow boots ;
r = $29 - $23
= $6

The relative frequency for the event "spin a 3" is __?

Answer:0.04
Step-by-step explanation:
a 500-foot cable is attached to the top of a tower and is stretched tight to a point that is 350 feet away from the base of the tower. what is the angle of depression formed by the cable?;
Answers
The angle of depression formed by the cable is approximately 41.4 degrees.
The angle of depression is the angle formed by the horizontal line and the line of sight from the observer to an object that is lower than the observer's position. In this case, the observer is at the top of the tower and the object is at the end of the cable that is stretched to a point 350 feet away from the base of the tower.
To find the angle of depression, we can draw a diagram as follows:
where h is the height of the tower, d is the horizontal distance from the base of the tower to the point where the cable is attached, and θ is the angle of depression that we want to find.
From the diagram, we can see that
tan(θ) = h / d
We know that the length of the cable is 500 feet and the horizontal distance from the base of the tower to the point where the cable is attached is 350 feet. We can use the Pythagorean theorem to find the height of the tower:
h^2 = 500^2 - 350^2
h = sqrt(500^2 - 350^2)
h = 300
Now we can substitute the values we have found into the equation for tan(θ) to get:
tan(θ) = 300 / 350
θ = tan^-1(300/350)
θ ≈ 41.4 degrees
