c. Translate down 4 units, then rotate 180° about the origin
d. Translate 4 units to the right, then rotate 180° about the origin

Answer:

c. CBA = PQR

Step-by-step explanation:

The match can be scheduled in 900 different ways.

Here, the number of players from each school = 3.

Let us assue that the players of the first school be A, B, and C.

And the players of the second school be X, Y, and Z.

Here, each player from the first school has to play twice with each player from the second school.

We can organize the schedule into six different rounds, i.e.,

R1 : AX BY CZ

R2 : AX BZ CY

R3 : AY BX CZ

R4 : AY BZ CX

R5 : AZ BX CY

R6 : AZ BY CX

So, the number of possible ways to do this would be : 6! = 720 ways.

Now, three rounds are played simultaneously in each round.

R1 : AX BZ CY

R2 : AX BZ CY

R3 : AY BX CZ

R4 : AY BX CZ

R5 : AZ BY CX

R6 : AZ BY CX

And R1 : AX BY CZ

R2 : AX BY CZ

R3 : AY BZ CX

R4 : AY BZ CX

R5 : AZ BX CY

R6 : AZ BX CY

The total number of possible ways for the second case would be twice of  6! / (2! 2! 2!), which is equal to 90+ 90 = 180.

Therefore, the total number of ways in which the match can be scheduled is 720 + 180 = 900.

Probability are important information when applying descriptive statistics. Probability is the branch of mathematics concerning numerical descriptions. the correct option is (B).

Descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.

here, we have,

A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).

The probability formula defines the likelihood of the happening of an event. It is the ratio of favorable outcomes to the total favorable outcomes. The probability formula can be expressed as,

Probability formula:

P(A) = Probability(Event) = Favorable Outcomes/Total Outcomes

P(A) =   x/n

where,

P(B) is the probability of an event 'B'.

n(B) is the number of favorable outcomes of an event 'B'.

n(S) is the total number of events occurring in a sample space

Descriptive statistics are brief informational coefficients that summarize a given data set, which can be either a representation of the entire population or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

The main purpose of descriptive statistics is to provide information about a data set. In the example above, there are hundreds of baseballs players that engage in thousands of games. Descriptive statistics summarizes the large amount of data into several useful bits of information.

The specific heat of a substance can be calculated by using the formula q = m × c × ΔT

Specific heat is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius

The specific heat of a substance can be calculated using the following formula:

q = m × c × ΔT

where:

q is the amount of heat energy transferred to or from the substance

m is the mass of the substance

c is the specific heat of the substance

ΔT is the change in temperature of the substance

To calculate the specific heat, we rearrange the equation as follows:

c = q / (m × ΔT)

To perform the calculation, you need to know the mass of the substance, the amount of heat energy transferred to or from the substance, and the change in temperature of the substance. You can then plug these values into the equation to find the specific heat. The units of specific heat are J/(kg*K) in SI units.

543 cubic centimeters has 0.543 L approximate displacement

Engine displacement means the displacement of the piston inside cylinder from Bottom Dead Center into Top Dead Center in one cycle.

Basic formula to calculate engine displacement is

V = π/4 x \(D^{2}\) x H x N

Where :

D = Bore Diameter

H = Length of Stroke

N = Number of Cylinder

Since the question has already stated cubic centimeter, it has already show the displacement. So, we can ignore above formula and the 4 cylinder engine information.

First, we state what is known. It is the displacement at cubic centimeter

Cubic centimeter = 543 cc

Next, we change the unit of cubic centimeter ( cc ) into liter ( L )

Displacement = cc / 1000 L

The answer would be (7, 18)

Step-by-step explanation:

The answers simple,

in the equation y=|-3x+3|

x and y would be said like this (x,y). just like the answer choices

now in the first option, x is R, so i couldn't understand that. so I'm gonna skip that.

in the second one, (7,0) would no work as

0=|-3(7) + 3|

0=|-21+3|

0=|-18|

and since "|" is absolute value, meaning that instead of the number being negative or positive the number will just be translated into how much distance is from the number and 0, or just make the number positive.

lets continue,

0=18, so (7,0)

the second one, (7,-18)

-18=|-3(7)+3|

-18=|-18|

again, its absolute value so

-18=18, so it still doesn't work

the last one, (7,18)

18=|-3(7)+3|

18=|18|

18=18

so (7,18) would work.

The equation when solved for the variable 'c' is c = P-5/ 2

A subject of formula can be defined as the variable that is written or denoted in terms of other variables in an equation or expression.

It is known as the variables being worked out in an equation. It is allowed to stand on its own over the equality sign.

Given the equation;

P = 2c + 5

To make the variable 'c' the subject of formula, we take the following steps:

Take 5 over the equality sign

P - 5 = 2c

Now, divide both sides by the coefficient of 'c' which is 2

2c/ 2 = P - 5/ c

Find the quotient

c = P-5/ 2

Thus, the equation when solved for the variable 'c' is c = P-5/ 2

A) The probability that all 6 brands could be identified by just guessing is 1/1716.

B) The probability that all 3 brands are identified correctly by just guessing is 1 / 2197.

(A) To calculate the probability that all 6 brands could be identified by just guessing, we need to find the size of the sample space S and the favorable outcomes.

The sample space S is the set of ways that 6 distinct brands can be chosen from the 13 popular brands of beer. The number of elements in the sample space is given by the combination formula:

n(S) = C(13, 6) = 13! / (6! * (13 - 6)!) = 1716.

Now, we need to determine the favorable outcomes, which is the number of ways to choose all 6 brands correctly by guessing. Since each brand has an equal chance of being selected, the probability of guessing a brand correctly is 1/13. Therefore, the favorable outcomes would be 1.

The probability is given by the ratio of favorable outcomes to the total outcomes:

Probability = favorable outcomes / total outcomes = 1 / 1716.

So, the probability that all 6 brands could be identified by just guessing is 1/1716.

(B) If repeats are allowed, the probability that all 3 brands are identified correctly by just guessing can be calculated as follows:

Since repeats are allowed, there are 13 possible choices for each brand. So, the favorable outcomes would be 1 out of 13³ possible outcomes (13 choices for each of the 3 brands).

Therefore, the probability is:

Probability = favorable outcomes / total outcomes = 1 / (13³).

= 1 / 2197

Hence, the probability that all 3 brands are identified correctly by just guessing is 1 / 2197.

The standard error of the distribution of sample proportions is 0.017. This means that if we take many random samples of size 800 from a population with proportion 0.60, the sample proportions will be normally distributed with a mean of 0.60 and a standard deviation of 0.017.

The standard error of the distribution of sample proportions is calculated using the following formula:

SE = sqrt(p(1-p)/n)

where:

p = the population proportion

n = the sample size

In this case, p = 0.60 and n = 800.

Plugging these values into the formula, we get:

SE = sqrt(0.60(1-0.60)/800) = 0.017
