Triangle ABC has coordinates A(4,-2), B(5,5), C(-1,3). Determine if triangle ABC is an equilateral triangle.
Triangle ABC is an ........ triangle because ..........
Triangle ABC's sides are not equal in length, hence it's not an equilateral triangle.
What does Class 7 equilateral triangle mean?It has three equal sides. The three angles are equal. Every edge of an equilateral is 60 degrees since the total of the inner angles equals 180 degrees. It has three regular sides and is a polygon. A vertex's height and median are represented by a single line.
What is equilateral, exactly?A triangular with equally length sides is known as an equilateral in geometry. The three angles opposing the three equal sides are equal in size because the three are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle.
Using the distance formula, we can find the lengths of the three sides:
[tex]AB = \sqrt{((5 - 4)^2 + (5 - (-2))^2)} = \sqrt{(2^2 + 7^2)} = \sqrt{(53)}[/tex]
[tex]BC = \sqrt{((-1 - 5)^2 + (3 - 5)^2) } = \sqrt{((-6)^2 + (-2)^2)} = \sqrt{(40)}[/tex]
[tex]CA = \sqrt{((4 - (-1))^2 + (-2 - 3)^2)} = \sqrt{(5^2 + 5^2)} = \sqrt{(50)}[/tex]
Since AB, BC, and CA have different lengths, the triangle is not equilateral.
Therefore, the answer is: Triangle [tex]ABC[/tex] is not an equilateral triangle because its sides have different lengths.

Since AB and AC have the same length, but BC has a different length, Therefore, ΔABC is not an equilateral triangle.
What is an equilateral triangle?Equilateral triangles are those with three sides that are all the same length.
In other words, all three sides of an equilateral triangle are of the same length, and all three angles within the triangle are also equal to 60 degrees.
Equilateral triangles are a type of regular polygon, which means that they have congruent sides and congruent angles.
Triangle ABC is not an equilateral triangle because its side lengths are not all equal.The lengths of the sides can be determined using the distance formula:
AB = √((5-4)² + (5-(-2))²) = √(1 + 49) = √(50)
BC = √((5-(-1))² + (5-3)²) = √(36 + 4) = √(40)

an algebra class has 8 students and 8 desks. for the sake of variety, students change the seating arrangement each day. how many days must pass before the class must repeat a seating arrangement? days must pass before a seating arrangement is repeated. suppose the desks are arranged in rows of 4. how many seating arrangements are there that put larry, moe, curly, and shemp in the front seats? there are seating arrangements that put them in the front seats. what is the probability that larry, moe, curly and shemp are sitting in the front seats? the probability is .
Solving the probability and permutations, we get (a) 20,160. (b) Larry, Moe, Curly, and Shemp can be arranged in the four front seats in 24 ways, and the ILB block can be arranged with the remaining students in 720 ways, and (c) 1/280.
(a) The number of possible seating arrangements can be calculated using the formula for permutations of n objects taken r at a time: P(n,r) = n!/(n-r)!. In this case, there are 8 students and 8 desks, so there are 8! possible seating arrangements.
To find the number of days before a seating arrangement is repeated, we need to subtract 1 from this number (since the first day is a unique arrangement) and divide by 2 (since there are two possible ways to arrange the students in any given seating arrangement, by simply rotating the arrangement). So the number of days before a seating arrangement is repeated is (8! - 1)/2 = 20,160.
(b) Larry, Moe, Curly, and Shemp must occupy the four front seats, so we need to choose four of the remaining four desks for the other students to sit at. This can be done in 4!/(4-4)! = 4! = 24 ways.
(c) We can treat the block of three students (ILB) as a single object, and then arrange the five remaining objects (M, O, A, X, and the ILB block) in a row. The ILB block can be arranged in 3! = 6 ways, and the other five objects can be arranged in 5! = 120 ways.
So the total number of potential seating arrangements in which ILB remains together is 6 x 120 = 720.
(d) The probability that Larry, Moe, Curly, and Shemp are sitting in the front seats is the number of possible seating arrangements in which they occupy the four front seats (24, from part b) divided by the total number of possible seating arrangements ([tex]8![/tex], from part a). So the probability is 24/8! = 1/280.

Suppose you toss two number cubes. Find the probability that both cubes will show a 4.
Therefore, the probability of both cubes showing a 4 is 1/36 or approximately 0.028 or 2.8%.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to occur. Probability can also be expressed as a percentage between 0% and 100%, with 0% indicating impossibility and 100% indicating certainty.
In probability theory, the probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, if you flip a fair coin, there are two possible outcomes: heads or tails. Since each outcome is equally likely, the probability of getting heads is 1/2 or 0.5 or 50%.
Assuming that the number cubes are fair and each face has an equal chance of landing face up, the probability of getting a 4 on any one of the cubes is 1/6, since there are six equally likely outcomes (numbers 1 to 6) and only one of them is a 4.
To find the probability of getting a 4 on both cubes, we need to multiply the probability of getting a 4 on the first cube by the probability of getting a 4 on the second cube, since the outcomes of the two cubes are independent of each other.
So, the probability of getting a 4 on both cubes is:
1/6 x 1/6 = 1/36
Therefore, the probability of both cubes showing a 4 is 1/36 or approximately 0.028 or 2.8%.

A company is marketing a new video game. Market research indicates that 24% of the the market has seen an advertisement for the new game.
Suppose 42% of those who see the ad have purchased the game and 93% of those who have not seen the advertisement have not purchased the game. If you choose a person who purchased the game, what is the probability he or she did not see the ad?
Express your answer as a decimal, rounded to the nearest thousandth (three decimal places).
Answer =
The probability that a person who purchased the game did not see the advertisement is:0.659.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. Probability is used in many areas, including statistics, mathematics, science, finance, and gambling.
In the given question,
To solve this problem, we will use Bayes' theorem, which allows us to update our beliefs about the probability of an event based on new information.
Let A be the event that a person has seen the advertisement, and B be the event that a person has purchased the game. We want to find the probability of A given B, i.e., the probability that a person who has purchased the game has also seen the advertisement.
We know that P(A) = 0.24 (24% of the market has seen the advertisement), P(B|A) = 0.42 (42% of those who see the ad have purchased the game), and P(~A|~B) = 0.93 (93% of those who have not seen the advertisement have not purchased the game).
We can use the complement rule to find P(B|~A), the probability of purchasing the game given that the person has not seen the advertisement:
P(B|~A) = 1 - P(~B|~A) = 1 - 0.93 = 0.07
Now we can use Bayes' theorem:
P(A|B) = P(B|A) * P(A) / P(B)
where P(B) = P(B|A) * P(A) + P(B|~A) * P(~A)
Plugging in the values, we get:
P(B) = 0.42 * 0.24 + 0.07 * (1 - 0.24) = 0.2956
P(A|B) = 0.42 * 0.24 / 0.2956 = 0.3408
Therefore, the probability that a person who purchased the game did not see the advertisement is:
1 - P(A|B) = 1 - 0.3408 = 0.659
Rounded to the nearest thousandth, the answer is 0.659.

Find the probability that a randomly selected point within the square falls in the red shaded area
The probability that a randomly selected point within the square falls in the red shaded area is approximately 0.2146 or about 21.46%.
To find the probability that a randomly selected point within the square falls in the red shaded area, we need to compare the area of the red shaded region to the area of the entire square.
Let the side length of the square be 2 units, and let the center of the circle be at the center of the square. Then, the radius of the circle is also 1 unit.
The area of the square is [tex](side length)^2[/tex] = [tex]2^2[/tex] = 4 square units.
The area of the circle is π[tex](radius)^2[/tex] = π[tex](1)^2[/tex] = π square units.
The red shaded area is the difference between the area of the square and the area of the circle, which is 4 - π square units.
Therefore, the probability that a randomly selected point within the square falls in the red shaded area is:
(red shaded area) / (area of the square) = (4 - π) / 4 ≈ 0.2146
So the probability is approximately 0.2146 or about 21.46%.

how to calculate a baseball player has a batting average of 0.365. what is the probability that he has exactly 1 hits in his next 7 at bats? Round your answer to four decimal places. The probability the baseball player has exactly 4 hits in his next 7 bats is
The probability that the baseball player has exactly 1 hit in his next 7 at-bats is 0.2908, rounded to 4 decimal places.
It is a statistic that measures the performance of baseball players. It is the ratio of the number of hits to the number of at-bats.
Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1.
Static means the precise value of something, without approximation or estimation.
It is a process of approximating a number to a specific number of decimal places.
A baseball player has a batting average of 0.365. The probability that he has exactly 1 hit in his next 7 at-bats is to be found.
Step 1: Calculate the probability of getting a hit in one at-bat. The probability of getting a hit in one at-bat is equal to the batting average of the player.
P(hit) = 0.365
Step 2: Calculate the probability of not getting a hit in one at-bat. The probability of not getting a hit in one at-bat is equal to the difference between 1 and the batting average.
P(not hit) = 1 - 0.365 = 0.635
Step 3: Calculate the probability of getting exactly 1 hit in 7 at-bats. The probability of getting exactly 1 hit in 7 at-bats can be calculated using the binomial probability formula:
P(1 hit in 7 at-bats) = 0.2908 (rounded to 4 decimal places)

alemu earn birrs 10000 per month,calculate
a, the income tax he has to pay
b.the net income after deducting income tax
Alemu's net income after deducting income tax is 9,470 birrs per month, assuming he lives in Ethiopia and the income tax rates for the current tax year apply.
We must take into account the income tax rates in Alemu's nation for the current tax year in order to determine how much income tax he must pay. We cannot provide an exact response since we are unsure about Alemu's country of residence. The income tax rates in Ethiopia, where the first 6,000 birr of income are tax-free and the remaining amount is subject to progressive taxes, range from 10% to 30%, can be used as an example, though.
Alemu's monthly taxable income, assuming he resides in Ethiopia, would be 4,000 birrs (between 10,000 and 6,000). He must pay the following amount of income tax:
180 birr (10% of the first 1,800 birr)
15% of the following 1,800 birrs is 270 birrs.
80 birrs are 20% of the remaining 400 birrs.
Alemu would therefore pay 530 birrs in total income tax each month.
Alemu's net income would be 9,470 birrs after income tax. This is the sum of cash he would have on hand to cover personal costs, savings, investments, and any other debts. It is crucial to remember that the net income amount may change depending on a number of variables, including deductions for social security, health insurance, or any other needed legal payments.
In conclusion, assuming Alemu lives in Ethiopia and the income tax rates for the current tax year are applicable, Alemu's net income after income tax is 9,470 birrs each month.

What is corresponding side?
In geometry, when two figures are similar, their corresponding sides are the sides that are in the same position and have the same relative orientation in each figure.
For example, consider two triangles ABC and DEF, where angle A is congruent to angle D, angle B is congruent to angle E, and angle C is congruent to angle F. If the length of AB is proportional to the length of DE, BC is proportional to EF, and AC is proportional to DF, then side AB corresponds to side DE, side BC corresponds to side EF, and side AC corresponds to side DF.
To list all the corresponding sides of two triangles ABC and A'B'C', we need to identify which side of triangle ABC corresponds to which side of triangle A'B'C'. Corresponding sides are those that are in the same position relative to each triangle.
We can identify the corresponding sides by comparing the positions of the vertices. For example, the side opposite vertex A in triangle ABC corresponds to the side opposite vertex A' in triangle A'B'C'. Similarly, the side opposite vertex B in triangle ABC corresponds to the side opposite vertex B' in triangle A'B'C', and so on.
Therefore, the corresponding sides are side AB corresponds to side A'B', side BC corresponds to side B'C', side AC corresponds to side A'C'.

How to solveTo determine the correct dosage, we first need to find out how much paracetamol the child needs based on their weight and then convert that amount to the appropriate volume of the medicine.
Calculate the required amount of paracetamol based on the child's weight:
Child's weight: 14 kg
Dosage: 15 mg per 2 kg of body weight
Required_paracetamol = (Child's weight / Dosage per kg) * Dosage
Required_paracetamol = (14 kg / 2 kg) * 15 mg

What is mean?In statistics, the mean is a measure οf central tendency οf a data set, alsο referred tο as the average. It is calculated by summing up all the values in the data set and then dividing by the tοtal number οf values. The mean represents the typical οr cοmmοn value in the data set.
The mean of the given data set is:
(135 + 115 + 120 + 110 + 110 + 100 + 105 + 110 + 125) / 9 = 114.44 (rounded to the nearest tenth)
To find the median, we first need to arrange the data set in ascending order:
100, 105, 110, 110, 110, 115, 120, 125, 135
Since the data set has an odd number of values, the median is the middle value, which is 110.
To find the standard deviation, we first need to calculate the variance. The variance is the average of the squared differences between each value and the mean. We can use the following formula to calculate the variance:
variance = [(value1 - mean)² + (value2 - mean)² + ... + (value9 - mean)²] / 9
Plugging in the values from the data set and the mean we calculated earlier, we get:
variance = [(135 - 114.44)² + (115 - 114.44)² + ... + (125 - 114.44)²] / 9
Simplifying this expression, we get:
variance = 102.46
The standard deviation is the square root of the variance, which is:
[tex]\sqrt{(102.46)[/tex] = 10.12 (rounded to the nearest tenth)

The equation for the line of best fit is a useful tool in data analysis to describe the relationship between two Variables and make predictions based on that relationship.
The equation for the line of best fit is a mathematical formula that describes the relationship between two variables in a data set. It is used in regression analysis to estimate and predict the value of one variable based on the value of another.
To find the equation for the line of best fit, we use the method of least squares, which minimizes the sum of the squares of the differences between the observed data points and the predicted values from the equation.
The equation takes the form of y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. The slope represents the rate of change of y with respect to x, and the y-intercept is the value of y when x = 0.
The coefficient of determination, denoted as r, is a measure of how well the line fits the data. It ranges from -1 to 1, where a value of 1 indicates a perfect fit, and a value of 0 indicates no correlation. A negative value indicates an inverse relationship.
In summary, the equation for the line of best fit is a useful tool in data analysis to describe the relationship between two variables and make predictions based on that relationship.

=> Monthly Rate of Change equals 100% * (e^(Monthly Rate) - 1)
By substituting the previously calculated monthly rate, we obtain:
=> [tex](e^{(0.045)} - 1)[/tex]* 100% = 4.56% for the monthly rate of change.
In light of this, the monthly percentage rate of change is roughly 4.56%, to the closest hundredth of a percent.

The altitude of an airplane is decreasing at a rate of 44 feet per second. What is the change in altitude of the airplane over a period of 37 seconds?
the altitude of the airplane would decrease by 1628 feet over a period of 37 seconds.
What is Rate?
A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.
When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized. When referring to the ratio of one quantity "to" the second quantity in spoken language, it is frequently written with a colon.
To find the change in altitude, we need to multiply the rate of decrease by the time period:
change in altitude = rate of decrease × time period
So, in this case:
change in altitude = 44 feet/second × 37 seconds
change in altitude = 1628 feet
Therefore, the altitude of the airplane would decrease by 1628 feet over a period of 37 seconds.

The tree's height changes 2.5ft bases per time.
What's the rate of change?The rate of change function is defined as the rate at which one volume changes relative to another volume. In simple terms, the rate of change is the quantum of change in one item divided by the corresponding quantum of change in another.
Equation:We can find the rate of change in the tree's height by calculating the slope of the line that represents the direct function relating the tree's height to the number of times since it was planted.
To do this, we can use the slope formula
Slope = ( change in height)/( change in time)
Let's choose the points
( 1,4.5) and( 4, 12)
Change in height = 12-4.5 = 7.5
Change of time = 4- 1 = 3
Slope = (7.5/ 3) = 2.5
So, the tree's height changes 2.5 bases per time.

B -23 and 4 over 7 in2
C -47 and 1 over 7 in2
D - 84 and 6 over 7 in2
A,B,C,D which one
Answer:
Step-by-step explanation:
Surface area of a cylinder = 2πr(r + h)
radiius = 1/2 diameter so the radius is 1/2 of 2 = 1
Surface are = 2(22/7)(1 )[(1 + 1.25)]
44/7 (2.25) = 99/7
This is for ONE muffin - mulitply by 6 to find out how much paper for

The option B is the correct answer for the above question. The line of symmetry should have been 4 instead -4 is correct.
How to find the symmetry?Line of symmetry - A line of symmetry is a line in mathematics that splits a form or object into two congruent halves, such that if one portion is reflected over the line of symmetry, it will coincide with the other component. A line of symmetry is also known as an axis of symmetry.
Now, we will see to find the line of symmetry for the quadratic equation [tex]f(x) = x^2 - 8x + 15[/tex],
Line of symmetry: [tex]x = \frac{-b}{2a}[/tex]
Vertex: [tex](x,y) = (\frac{-b}{2a}, f(\frac{-b}{2a}))[/tex]
where a, b, and c are the coefficients of the quadratic equation [tex]ax^2 + bx + c.[/tex]
In this case, [tex]a = 1, b = -8, and\ c = 15[/tex], so we can substitute these values into the formulas:
Line of symmetry: [tex]x = \frac{-(-8)}{21} = 4[/tex]
And, From this value of x, we will get the correct value of y.

The values of the sides are;
11. SR = 25
12. RU = 25
13. SU = 35.4
14. Perimeter = 100 units
15. Area = 625 square units
How to determine the valueIt is important to note that a square have 4 equal sides and 4 equal angles.
From the information given, we have that;
Line SR = line RU
But we have that;
SR = 2k + 7
RU = 3k - 2
Equate the sides, we have;
2k + 7 = 3k - 2
collect the like terms
2k - 3k = - 2 - 7
subtract the terms
-k = - 9
k = 9
Then, SR =2(9) + 7 = 25
RU = 3(9) - 2 = 25
The line SU is the hypotenuse side
Using the Pythagorean theorem
SU² = 25² + 25²
SU² = 625 + 625
SU = √1250
SU = 35. 4
15. The perimeter of a square is expressed as;
Perimeter = 4a
Perimeter = 4(25)
Perimeter = 100 units
16. The area of a square is expressed as;
Area = a²
Area = 25²
Area = 625 square units
