The probability that the next person will purchase more than one costume will be 1/30.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

Total visitors of a day = 81 + 6 + 3 = 90

The number of purchasing more than one costume = 3

Probability of purchasing more than one costume = 3/90 = 1/30

Hence"The probability that the next person will purchase more than one costume will be 1/30".

The confidence interval for the given equation will be: 0.504.

What is confidence interval?

In frequency statistics, the confidence interval (CI) is the range of estimated values ​​for an unknown parameter. Confidence intervals are computed at the specified confidence level. A 95% confidence level is the most common, but other levels such as 90% and 99% are sometimes used. The confidence level represents the proportion of corresponding CIs over time that contain the true value of the parameter. For example, 95% of all intervals computed at the 95% level must contain the true value of the parameter.

Factors that affect the width of the CI include sample size, sample variability, and confidence level. All else being equal, a larger sample results in a narrower confidence interval, a more varied sample results in a wider confidence interval, and a higher confidence level results in a wider confidence interval.

Therefore, The confidence interval for the given equation will be: 0.504.

The confidence level is 60600<μ<3,524.786, assuming a standard deviation of $13,553 and the confidence level for estimating the population mean is 90%.

What do you mean by confidence level?

A confidence interval is a range of values that can contain the true value of the parameter being studied in statistics. It is created using observed data and calculated at a desired level of confidence.

The confidence level—for instance, a 95% confidence level—relates to the accuracy of the estimation process, not to the degree to which it is certain that the computed confidence interval contains the actual value of the parameter under investigation.

a=34.697, only one triangle is formed.

And B=40°.7'

A≈77°.79'.So, option A is correct.

Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one.

Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.

Given,

C​=61° 50, c​=31.2, b=23.6

Sine rule:

sin B/b=Sin C/c

sin B=b sin C/c

=(23.6 sin 61° 50)/31.2

sin B=0.65219

sin B=139.3

A+B+C=180

A=180-B-C

A=180-139.3-61.50

A= -20.8 which is not possible.

Because the angle must be positive.

sin B=sin 40.70

A+B+C=180

A=180-40.70-61.50

A=77.79'

sin A/a=sin C/c

a=c sin A/sin C

So, a=34.697

Only one triangle is formed

Partially decomposing a rational fraction, also known as partially expanding it, in algebra includes expressing the fraction as the sum of a polynomial and one or more fractions with a lower common denominator.

One technique for breaking down rational expressions into smaller partial fractions is partial fraction decomposition. This method serves the integration process better.

In order to integrate a rational function, it is condensed to a valid rational function. The integrand can be expressed as the sum of more elementary rational functions through the use of partial fraction decomposition.

Therefore, starting with the simplified solution and proceeding backwards, the final expression is “decomposed” into the original polynomial fractions.

Answer:

x <> -3, 8

Step-by-step explanation:

x² - 5x - 24 (the denominator of the fraction) must not be 0, because n/0 is not defined for any n.

since this is a quadratic equation, it must have 2 solutions.

therefore, the second answer must be right.

let's check.

a quadratic equation

has the solutions

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (5 ± sqrt((-5)² - 4×1×-24))/(2×1) =

= (5 ± sqrt(25 + 96))/2 = (5 ± sqrt(121))/2 =

= (5 ± 11)/2

x1 = (5 + 11)/2 = 16/2 = 8

x2 = (5 - 11)/2 = -6/2 = -3

Supplementary angles are two angles whose combined angle is 180 degrees. As shown below, the table of the proof that (1) is an addition to (3) can be completed.

Supplementary angles are two angles whose combined angle is 180 degrees. When a straight line crosses another line, two angles are created on either side of the initially imagined straight line. Two sets of additional angles make up those two-two angles. This implies that a straight line will be formed by the outside sides of any extra angles that are positioned next to one another.

For the demonstration that 1 is an addition to 3, the preceding table can be completed as shown below.

1) Line m in is parallel to line n;

2) ∠1 = ∠2  →  Corresponding angles

3) m∠1 = m∠2  →  Definition of Congruent angles

4) ∠2 and ∠3 for a linear pair  →  Adjacent angles on a straight line

5) ∠2 is supplementary to ∠3  →  Definition of linear pair

Answer:

(-3,6)

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] x + [tex]\frac{1}{4}[/tex] y = 1  Divide all the way through by 12 to clear the fraction

4x + 3y = 12  Add this to the second equation

2x -3y = -30

6x = -18   Divide both sides by 6

x = -3

Substitute -3 into either of the original equations to solve for y

4x + 3y = 12

4(-3) + 4y = 12

-12 + 4y = 12  Add 12 to both sides

4y = 24  Divide both sides by 4

Alternate hypothesis: H₁: population mean, μ < 36hours

b. Type 1 error: is an error made when we reject the null hypothesis, when the null hypothesis is true. This happens the significance level % of time. In our example, a type 1 error would be made when the population mean is actually greater than 36 hours, but we conclude that the population mean is less than 36 hours.

Type 2 error: is an error made when we fail to reject the null hypothesis, when the null hypothesis is false. This is represented by beta. In our example, a type 2 error would be made when the population mean is actually less than 36 hours, but we conclude that the population mean is not less than 36 hours.

c. The test is left tailed since the area of rejection is on the left side (less than side).

d. We would interpret that at x% confidence level (generally 95%), we reject the claim that the population mean is greater than 36 hours. We would conclude that we have enough evidence from the sample that the population mean is significantly less than 36, and hasn't happened as a matter of chance.

By solving a linear equation, we will see that the distance is 479.98 miles.

We know:

The rental has a base cost of $49.95 plus $1.19 per mile.

There is also an extra cost of $3.89 per gallon of gas, and with one gallon they can travel 18 miles, then there is another extra cost of:

$3.89/18 per mile.

Then, if you travel x miles, the total cost is given by the linear equation:

C(x) = $49.95 + ($1.19 + $3.89/18)*x

We want to find the value of x, number of miles, such that the total cost is $724.85, then we need to solve:

$724.85 = $49.95 + ($1.19 + $3.89/18)*x

Let's solve that for x:

$724.85 -  $49.95 = ($1.19 + $3.89/18)*x

$674.90 = ($1.19 + $3.89/18)*x

$674.90/($1.19 + $3.89/18) = x

479.98 = x

Answer: i believe it is 14 too

Step-by-step explanation:

Answer:

16R = T or T = 16R

Step-by-step explanation:

R represents the unknown amount of rows and we know there are 16 boxes in each row.

This means to find the total number of boxes on display, you will have to times the number of rows by 16 as the clerk puts 16 boxes of cereal in each row

e.g, if there are 3 rows, then to find the total amount of cereal boxes, you would do 3 × 16 = 48

Since it's an expression, you need something to represent the total number so that can be represented by any letter ( I chose T ) — in most cases you can probably represent the total as x

Hence the expression should be 16R = T or T = 16R

Answer:

the sinusoidal function that approximates the hours of daylight in Miami has an amplitude of approximately 1.44 hours.

Step-by-step explanation:

The amplitude of a sinusoidal function is half the difference between the maximum and minimum values of the function. In this case, the shortest day in Miami is 10 hours and 52 minutes long, and the longest day is 13 hours and 45 minutes long, so the difference between the maximum and minimum values is 2 hours and 53 minutes, which is equal to 173 minutes. Half of this is 86.5 minutes, which is the amplitude of the function.

To express this in hours, divide the amplitude in minutes by 60. This gives an amplitude of 86.5 / 60 = 1.44 hours.

So, the sinusoidal function that approximates the hours of daylight in Miami has an amplitude of approximately 1.44 hours.

Given:- arithmetic sequence 20,18,16,14,....

To find:- 11th term of given arithmetic sequence

Arithmetic Progression (AP) is  sequence of numbers in order, in which the difference between any two consecutive numbers is  constant value. It is also known as Arithmetic Sequence.

The 11th term of the A.P. can be found by a formula, a(n)=a(1)+(n-1)d , where n is the number of terms, a(1) is teh first term of A.P and d is difference between any two continuously terms.

Number of terms to be found = 11

therefore, a(11) = a(1)+(n-1)d  

d=a(2)-a(1)

d=18-20

d=-2

putting value of d in above equation,

a(11) = 20 + (11-1)(-2)

a(11) = 20 -  20

a(11) = 0

hence the 11th term of arithmetic sequence 20,18,16,14,.... is 0.
