how many ways can the letters of the word dancer be arranged in a row if d and a must remain together (in order) as a unit?

Answer: y=-3

Step-by-step explanation:  In order to figure out what y would be in this problem, you would subtitute -1 in for x . and ask your self " What is 2* a -1? , The answer to that question would be -2 , ok. then the next step is to take the -2 and subtract by y which in case is 1 or -1 which will get you the answer of y=-3.

dx/dt = 4+3√3 in the case of the circle with radius 4 and the equation x²+y²=16.

The method of finding an implicit function's dependent variable's derivative by differentiating each term individually, symbolizing the derivative, and then solving the resulting expression for the symbol.

Without having to solve the provided equation for y, you may use the implicit differentiation technique to determine the derivative of y with respect to x.

Because we assume that y may be written as a function of x, the chain rule must always be applied when differentiating the function y.

So, the dx/dt will be:

The circle's equation is: x² + y² = 16

Assuming that x = 2, then:

2² + y²   = 16

y² = 12

y = ±√12

Hence, the first quadrant is positive:

y = √12

y = 2√3

When implicit differentiation is used, we get that:

2x dx/dt + 2y dy/dt = 16

If fracdydt = -3, as is the case, then

2(2) dx/dt - 12√3 = 16

4 dx/dt = 16 + 12√3

dx/dt = 16+12√3/4

dx/dt = 4+3√3

Therefore, dx/dt = 4+3√3 in the case of the circle with radius 4 and the equation x² + y² = 16.

Ginny initial charge = $80, Bob initial charge =$60 For the initial fee, Bob charges less than Ginny.

What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

Given that Ginny charges by uses the function f(x)=60x+80 where x represents the number of hours of labour.

Ginny initial charge = $80

Bob initial charge =$60

Hence, For the initial fee, Bob charges less than Ginny.

Professional tennis players may constitute a(n) symbolic group for an amateur tennis player

A symbolic group is one in which a person is unlikely to be accepted even if they act like a member by emulating their beliefs, attitudes, and behaviors. For young people, cricket players like Sachin Tendulkar, Sourav Ganguly, etc., may serve as a representative group. By concentrating on the small scale, symbolic interactionism examines the individual within a community and their relationships with others.

Similar to this, professional tennis players may serve as a symbolic group for an amateur tennis player who identifies with certain players by mimicking their behavior whenever possible, even though the amateur tennis player does not meet the criteria for membership in the category of professional tennis players because he or she does not have the necessary skills or access to the professional circuit.

Answer:

Shakira bowled 4 games.

Step-by-step explanation:

If Shakira paid $3 for rent, we can subtract 3 from 21.

21-3=18.

Now, find out how much 4.50 can go into 18.

First, multiply 4.50 by 2.

4.50x2=9

Now, Since 2 games is $9, multiply 9 by 2.

The name of the property is transitive property if 3x= 4 and 4=z then 3 =z.

According to the transitive property, "if two quantities are equal to the third quantity, then we can claim that all quantities are equal to each other." The term transitive refers to the act of transferring something. If a, b, and c are three quantities and an is connected to b by some rule and b is related to c by the same rule, then a and c are related to each other by the same rule; this is known as the transitive property of equality.

The transitive property of equality states that if a = b and b = c for any values of a, b, and c, then a = c. In other words, because a and c are both equal to the same item (in this case, b), they must be equal as well.

Given,

The more coins that are tossed for both gamblers, the less advantageous Gambler A is. But when a few coins are tossed, Gambler A will continue to hold a significant edge.

The binomial distribution;

In probability theory and statistics, the binomial distribution with parameters n and p is used to describe the discrete probability distribution of the number of successes in a set of n independent experiments.

Let X be the number of wins in the first n flips by A, Y be the signal that the last flip by A also wins, and Z be the number of wins in the n flips by B.

As Y is unrelated to X and Z, the following follows:

P(X + Y > Z) = P(Y = 1) P(X ≥ Z) + P(Y = 0) P(X > Z)

= 1/2(P(X = Z) + 2P(X > Z))

P(X > Z) = P(Z > X)

Then we would calculate the Test statistic, viz, difference of means/ standard deviation.

Decision Rule:

If we find that the value of test statistic is more than the value of Z, i.e., the test statistic does not lie between -1.96 to +1.96, then, the difference would be significant and the null hypothesis must be rejected.

The standard error for sample means is equal to the sample standard deviation when the sample size is more than 30 is a "false" statement.

For the stated question-

Let's assume that our sample size is 30 and that the population standard deviation is 10.

standard error = 10/√30 = 1.83

Now let me use a sample size of 100 while keeping overall population standard deviation constant.

=10/10 = 1

It is obvious that with this sample size, the standard error will alter.

Therefore, when our sample size grows, the standard error will drop rather than stay the same.

The value for speed V is 188.15 m/s

It was given that a particle accelerates from rest with an acceleration of 3 m/s² to a speed V

It continues at this speed for time T and then decelerates to rest at 1.5m/s². The total time for the motion is 1 minute, and the total distance traveled is 1 km

During acceleration:

a = 3 m/s², at rest u = 0, t = T

V = u + at

V = 0 + 3T

V = 3T

During deceleration:

a = 1.5 m/s², t = 1 minute = 60 s, distance(s) = 1 km = 1000 m

V² = u² +2as

V² = (3t)² +2(1.5×1000)

V² = (3×60)² + 3000

Answer:

Use the Triangle Proportionality Converse. If the ratios are equal, then the lines are parallel.

The domain is the set of all words in the English language that has a partial order relation and not a total order relation.

Given:

The domain is the set of all words in the English language (as defined by, say, Webster's dictionary.

Assume,

The domain is the set of all words in the English language (as defined by, say, Webster's dictionary). Word x is related to word y if x appears as a substring of y. x is a substring of y if all the letters in x appear in consecutive order somewhere in y. For example, "logical" is a substring of "topological" because the letters l-o-g-i-c-a-l appear consecutively in the order of the word "topological". However, "local" is not a substring of "topological" because the letters l-o are separated from c-a-l by the letters g and i.

Now, x is related to y if x is a substring of y.

Considering the following points through the example:

(A) Clearly, x is a substring of itself. Therefore, x is related to x and hence it is called reflexive.

(B) If x is related to y or y is related to x then x =y and it is called antisymmetric.

(C) If x is related to y and y is related to û then we can say that x is related to û (i.e. if x is a substring of y and y is a substring of û then x is also inscribed in û. Hence, we called it transitive.

Hence, the order is not the total order relation. It is a partial order relation.

We would add and subtract about three standard deviations from the sample proportion to get a 99.7% (nearly full) confidence interval for the real population proportion.

A confidence interval is a range of estimates for an unknown quantity in frequentist statistics.

The most frequent confidence level is 95%, but other levels, such as 90% or 99%, are infrequently used for generating confidence intervals.

To obtain a 99.7% (almost complete) confidence range for the real population proportion, you would add and deduct around three standard deviations from the sample proportion.

A confidence interval is a range of values that are bound by the statistic's mean and that is likely to include an unidentified population parameter.

The proportion of probability, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn numerous times is referred to as the confidence level.
