The surface area of the triangular prism is 62 square units.
What is surface area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.
For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.
The side length of each of the three squares is 4 units.
The area of each would be:
4² = 16 sq. units.
For the three squares we have:
16(3) = 48 sq. units.
The area of each triangle is 7 sq. units.
This means together the area of the two triangles is 2(7) = 14 sq. units.
The surface area of the prism is:
14 + 48 = 62 sq. units.
Hence, the surface area of the triangular prism is 62 square units.

An equilateral triangle is similar to a scalene triangle.1) Always2) never3) sometimes
Option 3) Sometimes is the correct answer, Sometimes an equilateral triangle is similar to a scalene triangle.
If the respective sides are proportional and the corresponding angles are congruent, two triangles are comparable. An equilateral triangle has three congruent sides and three congruent angles, so any triangle that is similar to an equilateral triangle must also have three congruent angles. However, a scalene triangle has no congruent sides and no congruent angles, so it is possible for a scalene triangle to be similar to an equilateral triangle only if it has the same angle measurements as an equilateral triangle, but with different side lengths. Therefore, a scalene triangle can be similar to an equilateral triangle, but it is not always the case.
In general, if two triangles are similar, it means that they have the same shape but possibly different sizes. In the case of an equilateral triangle and a scalene triangle, if they are similar, then it means that the scalene triangle has the same angles as the equilateral triangle, but its sides are of different lengths. So it is possible for a scalene triangle to be similar to an equilateral triangle, but not in all cases.

Consider the function f(x) = (x - 3)^2
a. How could you restrict the domain of f(x) so that its inverse will be a function?
b. Graph f(x) with its restricted domain and then graph its inverse on the same set of axes.
c. Find the equation of the inverse of f(x) with its restricted domain.
Answer:
Step-by-step explanation:
a) As the function is a quadratic you could restrict the domain by taking only values either side of the line x = 3. This means the domain will be
a) 3<x<∞
Or
b) -∞<x<3
b) the graph is attached below.
c) The equation of the inverse of f(x) can be found by switching x and y:
X = (y-3)²
√x = y - 3
y = √x + 3
However this takes in positive and negative values of the square root function. So in order to restrict this, we can take the positive square root only.
Thus y = +√x + 3

A mandatory competency test for high school sophomores has a normal distribution with a mean of 400 and a standard deviation of 100. The bottom 1. 5% of students must go to summer school. What is the minimum score you would need to stay out of this group?
A minimum score of 182 is required to stay out of the bottom 1.5% of students and avoid going to summer school.
To find the minimum score required to avoid going to summer school, we need to determine the score that separates the bottom 1.5% of students from the rest of the distribution. This score is also known as the cutoff or the critical value.
We know that the test scores have a normal distribution with a mean of 400 and a standard deviation of 100. To find the critical value, we can use the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can standardize the test scores using the z-score formula:
z = (x - mu) / sigma
where x is the test score, mu is the mean, and sigma is the standard deviation.
Substituting the given values, we get:
z = (x - 400) / 100
To find the z-score corresponding to the bottom 1.5% of the distribution, we can use a standard normal table or a calculator. The area to the left of this z-score is 0.015, which corresponds to a z-score of approximately -2.17.
Now we can solve for x, the minimum score required to stay out of the bottom 1.5%:
-2.17 = (x - 400) / 100
x = -2.17 * 100 + 400

. BASKETBALL In 2005, the average ticket prices for Dallas Mavericks games and Boston Celtics games are shown in the table below. The change in price is from the 2004 season to the 2005 season. Team Average Ticket Price Change in Price Dallas $53.60 $0.53 Boston $55.93 –$1.08
a. Assume that tickets continue to change at the same rate each year after 2005. Let x be the number of years after 2005, and y be the price of an average ticket. Write a system of equations to represent the information in the table. b. In how many years will the average ticket price for Dallas approximately equal that of Boston?
Answer:
a. Let's call the average ticket price for Dallas in 2005 as "d" and the average ticket price for Boston in 2005 as "b". Then the system of equations can be written as:
y_d = d + 0.53x (where y_d represents the price of an average ticket for Dallas after x years)
y_b = b - 1.08x (where y_b represents the price of an average ticket for Boston after x years)
b. To find the number of years in which the average ticket price for Dallas will approximately equal that of Boston, we need to solve the equation y_d = y_b for x. Plugging in the equations for y_d and y_b, we get:
d + 0.53x = b - 1.08x
Rearranging and solving for x, we have:
1.61x = b - d
x = (b - d) / 1.61
Now we just need to plug in the values for d and b from the table:
d = 53.60
b = 55.93
x = (55.93 - 53.60) / 1.61 = 2.33 years
So it will take approximately 2.33 years for the average ticket price for Dallas to approximately equal that of Boston.
Step-by-step explanation:
Answer: a. Let x be the number of years after 2005, and y be the price of an average ticket. Then, we can write the following system of equations to represent the information in the table:
For Dallas:
y = 53.60 + 0.53x
For Boston:
y = 55.93 - 1.08x
This system of equations represents the average ticket price y for Dallas and Boston as a function of the number of years x after 2005, with the change in price from the 2004 season to the 2005 season given in the table.
b. To find the number of years when the average ticket price for Dallas will approximately equal that of Boston, we can set the two equations equal to each other and solve for x:
53.60 + 0.53x = 55.93 - 1.08x
2.33x = 2.33
x = 1
So, the average ticket price for Dallas and Boston will approximately equal each other after 1 year. Therefore, in 2006, the average ticket price for Dallas will approximately equal that of Boston.

The sum of the digits in a two-digit number is 14. If you reverse and double the original number, the sum is 222. Find the original number.
The original two-digit number is 11 * 10 + 3 = 113.
How to find the original two digit number?Let us correspond to the original two-digit number as "10x + y," with x and y showing the tens and units digits, respectively.
We know from the first piece of information:
x + y = 14
According to the second piece of information:
2(10x + y) + 10y + x = 222
When we simplify this equation, we get:
20x + 22y = 202
We get 10x + 11y = 101 by dividing both sides by 2.
We now have two equations with two variables that can be solved by substitution or elimination. For example, in the first equation, we can solve for x and then substitute into the second equation:
x = 14 - y\s10(14 - y) + 11y = 101
When we simplify this equation, we get: y = 3
Putting y = 3 back into the first equation yields: x = 11.
The original two-digit number is 11 * 10 + 3 = 113.

X = 11 when y = 4 when X=a+b+4 and a directly proportional to y squared , b is inversely proportional to y.
Given that a is directly proportional to y^2 and b is inversely proportional to y, we can write the following two relationships:
[tex]a = k * y^2[/tex]
[tex]b = m / y[/tex]
where k and m are constants. From the first equation, we can find the value of k when y = 2:
[tex]a = k * 2^2[/tex]
[tex]k = a / 4[/tex]
And from the second equation, we can find the value of m when y = 2:
[tex]b = m / 2[/tex]
[tex]m = 2b[/tex]
Substituting these values into the equation X = a + b + 4, we can find X when y = 2:
[tex]X = (k * 2^2) + (m / 2) + 4[/tex]
[tex]X = (a / 4) * 4 + 2b + 4[/tex]
[tex]X = a + 2b + 4[/tex]
[tex]X = 18[/tex]
We can now use the value of k and m to find X when y = 4:
[tex]X = (k * 4^2) + (m / 4) + 4[/tex]
[tex]X = (a / 4) * 16 + (2b) / 4 + 4[/tex]
[tex]X = 4a + 2b + 4[/tex]
Substituting the value of X = 18 when y = 2, we can solve for a and b:
18 = 4a + 2b + 4
14 = 4a + 2b
7 = 2a + b
Solving the system of equations for a and b, we find:
a = 5
b = 2
Finally, substituting these values into the equation X = a + b + 4, we can find X when y = 4:
X = (5) + (2) + 4
X = 11

The probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.
The table shows the information about the gym membership and lunch habits of 100 physical therapists.
Given that a physical therapist brings their lunch to work, we can use the information in the table to calculate the probability that they do not use the gym membership. To do this, we'll use the formula:
P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch)
We can use the information in the table to find the values of P(not using gym membership and brings lunch) and P(brings lunch).
P(not using gym membership and brings lunch) = 40/100 = 2/5
P(brings lunch) = 60/100 = 3/5
So, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is:
P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch) = (2/5) / (3/5) = 2/3
