The horizontal change from triangle ABC to triangle ABC include the following: A. right 5 units.
The vertical change from triangle ABC to triangle ABC include the following: C. down 2 units.
The translation rule in the standard format is: (x, y) → (x + 5, y - 2).
What is a translation?In Mathematics, the translation of a graph to the left is a type of transformation that simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation of a graph to the right is a type of transformation that simply means adding a digit to the value on the x-coordinate of the pre-image.
By translating the pre-image of triangle ABC horizontally right by 5 units and vertically down 2 units, the coordinate A of triangle ABC include the following:
(x, y) → (x + 5, y - 2)
A (3, 5) → (3 + 2, 5 - 2) = A' (5, 3).

At Springfield Middle School, there are n 7th graders, and p% of them play at least one sport. Which expression represents the number of students who do not play any sports? 4©Success Academy Charter Schools 2020 A p n B .01np 0C 100 (100−p)nD .01 (1−p)nE 00(1 )n 1 −p
Answer:
(1-0.01p)/n
Step-by-step explanation:
Mathematically;
Percentage of student playing at least one sport = 100% - Percentage of students playing no sport
Mathematically, that would be;
Percentage playing no sport = 100% - p%
So, to find this in n 7th graders
we have;
(100-p)/100 * n
= 100-P/100n = 1/n - P/100n
= 1/n - 0.01p/n
= (1-0.01p)/n

Answer:
\(y=-\dfrac{8}{x}\)
Step-by-step explanation:
Inverse proportions can be represented by an equation in the form:
\(\boxed{y=\dfrac{k}{x}}\)
where:
y and x are the two quantities in the proportion.k is the constant of proportionality.To write an expression for the graphed function, first input the given point (-2, 4) into the inverse proportion equation and solve for k:
\(\implies y=\dfrac{k}{x}\)
\(\implies 4=\dfrac{k}{-2}\)
\(\implies 4 \cdot (-2)=\dfrac{k}{-2}\cdot (-2)\)
\(\implies -8=k\)
\(\implies k=-8\)
Therefore, the expression for the graphed function is:
\(\boxed{y=-\dfrac{8}{x}}\)
two basketball teams play until one team wins two games. team a has probability 0.6 of winning each game while team b has probability of 0.4 of winning each game. if team a wins the first game what is the probability team b wins the series?
Answer:
0.16
Step-by-step explanation:
You want the probability that team b will win 2 games in a row, given that the probability of team a winning is 0.6, and the probability of team b winning is 0.4.
OutcomesAfter one win for team A, the series can have the possible outcomes ...
A – team a wins with probability 0.6
BA – team a wins with probability (0.4)(0.6) = 0.24
BB – team b wins with probability (0.4)(0.4) = 0.16
The probability of team b winning the series is 0.16.
__
Additional comment
The probability team a wins the series after winning the first game is 0.6 +0.24 = 0.84 (= 1 -0.16). At the beginning of the series, the probability b wins is 0.352, dropping dramatically after a wins the first game.
<95141404393>
The probability that Team B wins the series after Team A wins the first game is 0.4 or 40%.
What is probability?
Probability is a measure or quantification of the likelihood of an event occurring. It is a numerical value assigned to an event, indicating the degree of uncertainty or chance associated with that event. Probability is commonly expressed as a number between 0 and 1, where 0 represents an impossible event, 1 represents a certain event, and values in between indicate varying degrees of likelihood.
To determine the probability that Team B wins the series after Team A wins the first game, we need to consider the different possible outcomes of the remaining games.
Since the series continues until one team wins two games, there are three possible scenarios:
Team A wins the next game (Team A wins the series)
Team B wins the next game, followed by Team A winning the third game (Series tied at 1-1)
Team B wins both the next and third games (Team B wins the series)
We'll calculate the probabilities of these scenarios and then determine the probability of Team B winning the series.
Scenario 1: Team A wins the next game (Team A wins the series):
The probability of Team A winning the next game is 0.6.
Scenario 2: Team B wins the next game, followed by Team A winning the third game (Series tied at 1-1):
The probability of Team B winning the next game is 0.4.
The probability of Team A winning the third game is 0.6.
To calculate the probability of this scenario, we multiply the individual probabilities:
Probability = 0.4 * 0.6 = 0.24
Scenario 3: Team B wins both the next and third games (Team B wins the series):
The probability of Team B winning the next game is 0.4.
The probability of Team B winning the third game is 0.4.
To calculate the probability of this scenario, we multiply the individual probabilities:
Probability = 0.4 * 0.4 = 0.16
To find the probability of Team B winning the series, we add the probabilities of Scenario 2 and Scenario 3 since both outcomes result in Team B winning the series:
Probability = 0.24 + 0.16 = 0.4
Therefore, the probability that Team B wins the series after Team A wins the first game is 0.4 or 40%.

In reference to line items, how many permutations are possible with the letters "ABC"?
So there are 6 permutations possible with the letters "ABC". These are: ABC, ACB, BAC, BCA, CAB, CBA.
Permutations are a way of arranging objects in a specific order. The number of permutations of a set of n distinct objects is given by n!, where n! denotes the factorial of n.
In the case of the letters "ABC", there are three distinct objects: A, B, and C. Therefore, the number of permutations possible with these letters is:
3! = 3 x 2 x 1 = 6
This means that there are 6 possible ways of arranging the letters "ABC" in a specific order. These permutations are:
ABC
ACB
BAC
BCA
CAB
CBA
To see why there are 6 possible permutations, consider the first position. There are three letters to choose from, so there are three possible choices for the first position. Once the first letter is chosen, there are two letters left to choose from for the second position. Finally, there is only one letter left to choose from for the third position. Therefore, the total number of permutations is:
3 x 2 x 1 = 6
In summary, the number of permutations of a set of n distinct objects is given by n!, and in the case of the letters "ABC", there are 3! = 6 possible permutations: ABC, ACB, BAC, BCA, CAB, and CBA.

Consider a population with a known standard deviation of 27.5. In order to compute an interval estimate for the population mean, a sample of 69 observations is drawn. [You may find it useful to reference the z table.]
a. Is the condition that X−X− is normally distributed satisfied?
Yes
No
b. Compute the margin of error at a 99% confidence level. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.)
c. Compute the margin of error at a 99% confidence level based on a larger sample of 275 observations. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.)
d. Which of the two margins of error will lead to a wider confidence interval?
99% confidence with n = 69.
99% confidence with n = 275.
The margin of error at a 99% confidence level is 8.36.
The margin of error at a 99% confidence level based on a larger sample of 275 observations is 4.14.
a. Yes, the condition that X−X− is normally distributed is satisfied for a sample size of 69 by the central limit theorem.
b. The margin of error at a 99% confidence level can be computed using the formula:
Margin of error = z* (sigma / sqrt(n))
where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.
The z-score for a 99% confidence level is 2.576 (from the z table).
Substituting the given values, we get:
Margin of error = 2.576 * (27.5 / sqrt(69)) = 8.36
c. The margin of error at a 99% confidence level based on a larger sample of 275 observations can be computed using the same formula:
Margin of error = z* (sigma / sqrt(n))
where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.
The z-score for a 99% confidence level is still 2.576 (from the z table).
Substituting the given values, we get:
Margin of error = 2.576 * (27.5 / sqrt(275)) = 4.14
d. The margin of error is inversely proportional to the square root of the sample size. As the sample size increases, the margin of error decreases. Therefore, the margin of error with n = 275 will be smaller than the margin of error with n = 69, leading to a narrower confidence interval.

________ child tickets and _______ adult tickets.
Answer:
I think 36 for child and 18 for adult
Step-by-step explanation:
A cost function is a mathematical formula used to chart how production expenses will change at different output levels. Hence, \(25\) child tickets are sold and adults are \(15\).
What is the cost?
A cost function is a mathematical formula used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.
Let \(y\) be the number of child tickets sold
Then, \(40-y\) be the number of adults tickets sold
Each ticket costs $\(3\) and there are \(y\) child so it is of the form
\(3\)×\(y=3y\)
So, \(40-y\) tickets sold and each costs $\(5\), so it`s the cost is \(5(40-y)\).
\(3x+5(40-y)=150\\3y+200-5y=150\\200-2y=150\\-2y=150-200\\-2y=-50\\2y=50\\y=25\)

Calculating the Number of Periods [LO4] You expect to receive $39,000 at graduation in two years. You plan on investing it at 10 percent until you have $174,000. How long will you wait from now? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Period years
You would need to wait approximately 51.33 years from now to grow your initial investment of $39,000 to $174,000 at an interest rate of 10% per year.
To calculate the number of periods (years) required to grow an initial investment to a desired future value, we can use the formula for compound interest:
FV = PV * \((1 + r)^n\)
Where:
FV is the future value
PV is the present value (initial investment)
r is the interest rate per period
n is the number of periods
In this case:
PV = $39,000
FV = $174,000
r = 10% per year
Let's calculate the number of periods (years):
FV = PV * \((1 + r)^n\)
174,000 = 39,000 * \((1 + 0.10)^n\)
Divide both sides by 39,000:
4.4615 = \((1.10)^n\)
Take the logarithm of both sides to solve for n:
log(4.4615) = n * log(1.10)
n ≈ log(4.4615) / log(1.10)
n ≈ 2.1270 / 0.0414
n ≈ 51.33 (rounded to two decimal places)

Given AC = LN and BA = ML, which statement must be true?
BC < MN
BC > MN
BC = MN
BA = LN
Statement is true because the corresponding sides are congruent. The answer is: BA = LN.
What is Triangle?
A triangle is a closed, two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and is used in many areas of mathematics, science, and engineering.
Since triangle ABC and triangle LMN have congruent corresponding sides, we know that they are similar triangles. This means that their corresponding angles are also congruent.
We are given that angle BAC is 58 degrees and angle MLN is 78 degrees. Since corresponding angles are congruent, this means that angle BAC is congruent to angle MLN.
Therefore, triangle ABC and triangle LMN are similar triangles with two pairs of corresponding congruent angles. This means that all corresponding sides are proportional.
Since AC = LN and BA = ML, we know that the ratio of the lengths of corresponding sides is:
AC / LN = BA / ML
Substituting the given values, we get:
1 = 1
This statement is true because the corresponding sides are congruent.
Therefore, the answer is: BA = LN.

a fish tank has the capacity of 60 liters lily uses a 2000ml jug to put water in the fish tank she stops when the water is 4cm from the top work out the number of jugs of water lily uses
Answer: First, we need to convert the capacity of the fish tank from liters to milliliters since the jug size is given in milliliters.
60 liters = 60,000 milliliters
Next, we need to calculate the volume of water that is already in the tank up to the 4cm mark from the top. Let's assume the tank is a rectangular prism with a length of L, width of W, and height of H. Then, the volume of water up to the 4cm mark can be calculated as:
Volume of water = Length x Width x Height of water level
Volume of water = L x W x (H - 4)
Assuming the tank has a uniform cross-section, we can use the fact that the height of the water level is proportional to the volume of water. That is, if the water level is halfway up the tank, then the volume of water is half the total capacity of the tank.
Let's say the water level is at a height of h from the bottom of the tank. Then, the volume of water in the tank is:
Volume of water = (h / H) x 60,000 mL
We want to solve for h, the height of the water level when it is 4cm from the top. We know that the height of the tank is H, so we can set up a proportion:
(h / H) x 60,000 mL = (H - 4 cm) x L x W
Solving for h, we get:
h = [(H - 4 cm) x L x W x 60,000 mL] / [H x L x W]
h = 59,960 / H
Now, we can calculate the amount of water Lily needs to add to the tank to fill it up to the 4cm mark from the top:
Amount of water needed = 60,000 mL - Volume of water up to 4cm mark
Amount of water needed = 60,000 mL - [(H - 4 cm) x L x W]
We can now calculate the number of jugs of water Lily needs to use by dividing the amount of water needed by the capacity of each jug:
Number of jugs needed = Amount of water needed / 2000 mL
Number of jugs needed = [60,000 mL - (H - 4 cm) x L x W] / 2000 mL
Note that the number of jugs needed will depend on the dimensions of the tank and the height of the water level.

reference the following table: x p(x) 0 0.130 1 0.346 2 0.346 3 0.154 4 0.024 what is the variance of the distribution?
The variance of the distribution of the data set is 0.596.
To find the variance of a discrete probability distribution, we use the formula:
Var(X) = ∑[x - E(X)]² p(x),
where E(X) is the expected value of X, which is equal to the mean of the distribution, and p(x) is the probability of X taking the value x.
We can first find the expected value of X:
E(X) = ∑x . p(x)
= 0 (0.130) + 1 (0.346) + 2 (0.346) + 3 (0.154) + 4 (0.024)
= 1.596
Next, we can calculate the variance:
Var(X) = ∑[x - E(X)]² × p(x)
= (0 - 1.54)² × 0.130 + (1 - 1.54)² × 0.346 + (2 - 1.54)² × 0.346 + (3 - 1.54)² × 0.154 + (4 - 1.54)² × 0.024
