The odds against selecting a history are 31/16.

Probability is the concept that describes the likelihood of an event occurring. In many situations, it is necessary to foresee how something will turn out in the actual world. We may be aware of the result of an event or not. When this occurs, we state that there is a possibility that the event will occur.

Probability is the ratio of the most likely outcomes to all other possible outcomes of an event. The number of successful outcomes for an experiment with 'n' outcomes may be expressed using the symbol x. The following formula can be used to determine the likelihood of an event.

Probability(Event) = favorable outcome/Total outcome = x/n

Number of playwrights = 47

Number of histories = 16

Therefore, the odds against selecting a history are

(47 - 16) / 16

= 31/16

Linear equation of attendance in terms of the price is A = -225p + 4925

What is linear equation?

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

Attendance as a function of ticket price.

A(p) = mp + b

We have two points (p, A):  (15, 1550), (9, 2900)

Slope:  m = (2900-1550)/(9-15) = 1350/-6 = -225

A = -225p + b

Using (15, 1550) as (p, A) find b

1550 = -225(15) + b

1550 = -3375 + b

4925 = b

A = -225p + 4925

The cross product of  three vectors is not associative in nature.

Considering three vectors such  as : A=(2,1,3), B=(1,0,2) and  C=(1,1,0)

we  know that the  associative law depicts that :

A x (B x C) = (A x B) x C ,while doing the operation for the  considered vectors :

A x (B x C) =(2,1,3)x ((1,0,2)x (1,1,0))

                  =(2,1,3)x (-2,2,1)

     =(-5,-8,6)

(A x B) x C=  ((2,1,3)x (1,0,2))x (1,1,0)

            = (2,-1,1) x (1,1,0)

  =(-1,1,3)

So  for this vector operation, A x (B x C)  is not  equal to  (A x B) x C, so you can sum up that cross product of three vectors can't be associative every possible time.

A regular quadrilateral is one in which the lengths of all the sides and the measures of all the angles are equal. A regular quadrilateral must have all of its angles measured (6w 13°) if one of its angles does.

A quadrilateral's angles measure a total of 360 degrees. The total measure of the angles of a regular quadrilateral is 4 (6w 13)°, which equals 24w + 52°. A regular quadrilateral contains four angles, of which each measure (6w 13)°. Thus, we obtain the equation shown below:

24w + 52° = 360°

Solving for w, we get:

24w = 308°

w = 13

Consequently, w has a value of 13, and w = 13 is the right response.

Answer:105

Step-by-step explanation:

The speed of the bill's motor boat is found as 20 mph.

Here, we're trying to determine the motorboat's speed.

The speed on the skis would be (x + 10) mph if his motorboat speed is x mph.

There are four hours in all;

Speed = distance/time mathematically.

Skiing time is 27/x+10.

The motorboat time is 62/x.

The result of adding both is 4.

Thus;

27/(x + 10) + 62/x = 4

27(x) + 62(x + 10) = 4(x)(x + 10)

27x + 62x + 620 = 4(x² + 10x)

89x + 620 = 4x² + 40x

4x² -49x-620 = 0

By the quadratic formula;

{-b ± √(b²-4ac)}/2a

In which  a = 4, b = -49 and c = -620

= 49 ± √(-49)² -4(4)(-620)/8

Thus,

49+ 111/8 or 49-111/8

As, speed is not negative.

= (49 + 111)/8

= 20 mph

Thus, the speed of the bill's motor boat is found as 20 mph.

Let's solve your equation step-by-step.

−4(v+1)+6v=2(v+2)−8

Step 1: Simplify both sides of the equation.

−4(v+1)+6v=2(v+2)−8

(−4)(v)+(−4)(1)+6v=(2)(v)+(2)(2)+−8(Distribute)

−4v+−4+6v=2v+4+−8

(−4v+6v)+(−4)=(2v)+(4+−8)(Combine Like Terms)

2v+−4=2v+−4

2v−4=2v−4

the 95% confidence interval for the proportion of all dies that pass the probe is [0.513,0.616].

Sampling is frequently used to estimate the percentage of population that possesses a particular attribute, such as the percentage of all faulty goods which come off an assembly line or the percentage among all buyers that enter a store and make a purchase before leaving. The population proportion is indicated p, while the sample proportion is written p. Thus, if 43% of individuals visiting a business make a purchase before departing, p = 0.43; if 78 people enter the store and make a transaction, p=78/200=0.39.

The sample proportion is a random variable because it differs from sample to sample in ways that are impossible to anticipate in advance. When seen as a random variable, it will be represented by the letter P.

How to solve?

An article reported that in a study of a particular wafer inspection process, 356 dies were examined by an inspection probe and 169 of these passed the probe.

So,p'=201/356=0.56460

The 95% confidence interval for the proportion of all dies that passed the probe will be,

p∈[p'±zα/2√p'(1−p')/n]

p∈[0.56460±1.96×√0.56460(1−0.56460)356]

There are 96 ways for four people to sit in six chairs so that the leftmost chair is occupied and the rightmost is empty.

There are 4 guests and the leftmost seat is to be occupied, so there are 4  such ways to choose the occupant of that seat.

Then, for each of those 4 ways, there are 4 ways to decide the occupant for the second seat -- the remaining three people plus the possibility of that seat being empty, that makes a total of 16 ways to decide the configuration of the first two seats.

Then, for each of those 16 ways, there are 3 ways to choose the occupant for the third seat (either 3 remaining guests if the second seat was left empty, or the two remaining guests plus the possibility of leaving the 3rd seat empty). Hence, 16 times 3 is 48. For each of those ways, there are two choices for the next seat, i.e. 48 times 2 = 96, and finally one choice for the fifth seat. So in all, there are 96 ways.

For the first one
Part a:
115x + 685y >= 2300

Part b:
See explanation below

Second one:

1.5x + 1.0y >= 2000

Rest of explanation below

Step-by-step explanation:

First one.
Let x be the number of skimboards sold and y be the number of longboards sold.

Then revenue from sales of x units at $115 and y units at $685 would be

115x + 685y

This must be at lest the overhead to make zero loss

So the inequality is
115x + 685y ≥ 2300   (Answer a)

Part b

Any combination of x and y which satisfies this inequality will provide a profit. I have provided a graph of this inequality using an online graphing calculator. I am not sure what your teacher wants you to use.

Any point in the shaded region represents a combination of x and y which satisfies that inequality. However since you cannot sell a fraction of a surfboard, only points which represent whole numbers can be valid. Also only values of x and y >=0 can be chosen.  So any point in the shaded region which has x and y non-negative and x and y whole numbers will generate a profit

Again I am not sure whether this question is asking for a specific value or possible values.

A specific value can be (x=5, y = 10) which is well within the shaded region. This represents 5 skimboards and 10 longboards with a revenue of 5 x 115 + 10 x 685 = $ 7425

Or you could sell 0 skimboards and 4 longboards giving you a revenue of
4 x 685 = $2,740

Or 20 skimboards and zero long boards which is a revenue of $2300 which breaks even with the overhead

Second Question: Modeling
