Answer:

If it rides 5 miles it woul be 4.5 dollars but the other one would be 55$ dollars for just 5 miles.

Step-by-step explanation:

The formula for the height above the ground, h(t) is h(t) = 255 sin (π/20 t) + 20.

The amplitude is half the distance between the highest and lowest points, which is (530 - 20)/2 = 255 feet. So A = 255.

The period is 40 minutes, so B = 2π/40 = π/20.

At t = 0 (when we board the Ferris Wheel), we are 20 feet above the ground.

This means there is no phase shift, so C = 0.

The vertical shift is also 20 feet, so D = 20.

Putting it all together, we have:

h(t) = 255 sin (π/20 t) + 20

Answer:

Ok. So we have 12 different styles of watches to choose from, so that means that the total number of combinations of styles for 5 boys is 12*12*12*12*12, since each boy has his pick of 12 options.

The way to answer this question is by way of the complementary rule: We want the number of ways that the boys can all have different styles. So the first boy to pick has 12 options available to him, the second boy has 11 options available to him, the 3rd boy has 10 options available to him, so on and so forth.

So the probability that the boys all have different watches is (12*11*10*9*8)/12^5= .3819.

To find the probability that at least two boys have the same style would just be 1 -.3819 = 6181

Answer:

7. To perform a t-test when the sample size is small, the sample must show no evidence of strong skewness and must contain no outliers.

Step-by-step explanation:

These are the two conditions required for performing a t test

- Sample Size: A small sample size can reduce the statistical power of a t-test, making it more challenging to detect significant differences between groups. Generally, a larger sample size is desirable to obtain more reliable and representative results.

- Skewness: Skewness refers to the asymmetry of the distribution of data. In a t-test, assuming normality of the data is important for accurate results. If the data exhibits strong skewness, the assumption of normality may be violated. In such cases, alternative non-parametric tests or transformations of the data may be more appropriate.

- Outliers: Outliers are extreme values that significantly differ from the rest of the data. They can have a disproportionate impact on the results of a t-test, particularly when the sample size is small. Outliers can distort the mean and affect the assumptions of normality and homogeneity of variance.

While the presence of skewness or outliers does not prohibit the use of a t-test with a small sample size, it is important to interpret the results with caution and consider alternative approaches if necessary. Robust statistical methods, such as non-parametric tests or bootstrapping, can be useful when dealing with non-normal or outlier-prone data, especially with small sample sizes. Additionally, visual inspection of the data distribution, such as through histograms or box plots, can help identify potential skewness or outliers.

The numbers 1 through 9 can be divided into three groups, {1, 5, 9}, {3, 4, 8}, and {2, 6, 7}, where the sum of the numbers in each group is 15.

Here is one way to divide the numbers 1 through 9 into three groups so that the sum of the numbers in each group is the same:

Group 1: 1, 5, 9

Group 2: 3, 4, 8

Group 3: 2, 6, 7

The sum of the numbers in each group is 15. This can be verified by adding the numbers in each group together.

Group 1: 1 + 5 + 9 = 15

Group 2: 3 + 4 + 8 = 15

Group 3: 2 + 6 + 7 = 15

Answer:

the answr is 87 jistg ebcaujse

Step-by-step explanation:

3,500 tickets were sold for $15 each and 4,600 tickets were sold for $25 each.

Let x be the number of $15 tickets and y be the number of $25 tickets.

We know that:

x + y = 7,500 (the total number of tickets sold)

15x + 25y =  153,500 (the total amount of money made from ticket sales)

We can use the first equation to express y in terms of x:

y = 7,500  - x

We can substitute this expression of y into the second equation:

15x + 25(7,500  - x) = 153,500

Solving for x:

15x + 25(7,500) - 25x =  153,500

15x + 187500 - 25x =  153,500

-10x = -34,000

x = 3400

Therefore, 3,400 tickets were sold for $15 each and  7,500 - 3,500 = 4000 tickets were sold for $25 each.

Given:

Perimeter is:

or

The perimeter is at most 96 cm (not greater than):

The matching choice is A.

Therefore, WT > 17 and WT > 18, so the smallest possible value of WT is 18. Therefore, WT ≈ 18.

The product of the lengths of their crossed arcs, divided by two, determines the size of each angle formed when two secants or chords cross paths inside of a circle. An inscribed angle's measurement is equal to half of its intercepted arc's measurement.

m ZYX = m(arc WY) + m(arc ZX) = 44° + 68° = 112° since arc WY = 44° and arc ZX = 68°. (vertical angles).

The opposing angles in the cyclic quadrilateral ZTYX are additional. m ZTX = 180° - m ZYX = 180° - 112° = 68°, as a result.

As a result, m ZTX = 68°.

(2) The Pythagorean theorem can be used to determine the length of the missing side TZ because WTX is a right triangle:

WT² + TX² = TZ²

(4.8)² + (8.0)² = TZ²

23.04 + 64 = TZ²

87.04 = TZ²

TZ ≈ 9.33

Therefore, TZ ≈ 9.33.

(3) The Triangle Inequality Theorem gives us the following:

WT + TY > WY

WT + 8 > 25

WT > 17

WT + TX > WX

WT + 8 > 25

WT > 17

Consequently, WT can only have a minimum value of 18.

WT can have a minimum value of 18 since WT > 17 and WT > 18.

Therefore, WT ≈ 18.

No, the simple digraph with 3 vertices and in-degrees 0, 1, 2, and out-degrees 0, 1, 2 respectively does not exist, while the simple digraph with 3 vertices and in-degrees 1, 1, 1, and out-degrees 1, 1, 1 does exist.

What is digraph?

A digraph is a directed graph where each edge has a direction associated with it. In-degrees refer to the number of edges pointing into a vertex, while out-degrees refer to the number of edges pointing out of a vertex.

For the first case, having in-degrees of 0, 1, 2, and out-degrees of 0, 1, 2 for the three vertices is not possible. The sum of in-degrees must equal the sum of out-degrees in a digraph. However, in this case, the sum of in-degrees is 3 while the sum of out-degrees is 3, which does not match. Therefore, such a digraph does not exist.

For the second case, a simple digraph with in-degrees of 1, 1, 1, and out-degrees of 1, 1, 1 is possible. Each vertex has exactly one incoming edge and one outgoing edge, forming a cycle among the three vertices. This configuration satisfies the condition of a simple digraph, where each vertex has the same in-degree and out-degree.

The terms minimum and infimum are both related to the concept of lower bounds in mathematics. A minimum is the smallest value in a set of numbers, whereas an infimum is the greatest lower bound of a set.

A minimum is a value that is less than or equal to all other values in the set, while an infimum is a value that is less than or equal to all other values in the set, but not necessarily the smallest value.

For example, if we consider the set {2, 4, 6}, the minimum is 2 and the infimum is also 2. However, if we consider the set {2, 4, 6, 8}, the minimum is 2 and the infimum is 4. In the latter set, 4 is the greatest lower bound, meaning that all other values in the set are greater than or equal to 4.

To find out how the amount of fabric required to make the cylindrical bag compares to the amount of fabric required to make the square-based-prism bag, we can use the formula for the surface area of each shape.

The amount of fabric required to make a bag is proportional to its surface area. Therefore, we can compare the surface areas to determine which bag will require more fabric. Let's assume the dimensions of each bag are as follows:

Cylindrical bag: height = 10 inches,

radius = 5 inches
Square-based-prism bag: height = 10 inches,

base length = 6 inches,

base width = 6 inches

Now, let's find the surface areas of each bag:

Surface area of cylindrical bag = 2πrh + 2πr²
= 2π(10)(5) + 2π(5)²
= 100π + 50π
= 150π square inches

Surface area of square-based-prism bag = 2lw + 2lh + 2wh
= 2(6)(6) + 2(6)(10) + 2(6)(10)
= 72 + 120 + 120
= 312 square inches

Therefore, the square-based-prism bag requires more fabric than the cylindrical bag.

Next, let's find out how much each bag will hold. We can use the formula for the volume of each shape to find out. The volume of each bag will give us an idea of how much they can hold.

Volume of cylindrical bag = πr²h
= π(5)²(10)
= 250π cubic inches

Volume of square-based-prism bag = lwh
= 6(6)(10)
= 360 cubic inches

Therefore, the square-based-prism bag can hold more than the cylindrical bag.

Based on this information, the cpm sports company should make the square-based-prism bag if they want to maximize the amount of items each bag can hold.

However, if the company is more concerned with using less fabric to make each bag, then they should make the cylindrical bag. The decision ultimately depends on the company's priorities and goals.

The amount of fabric required to make the cylindrical bag is less than the square-based-prism bag. However, the square-based-prism bag can hold more than the cylindrical bag.

The cpm sports company should make the square-based-prism bag if they want to maximize the amount of items each bag can hold.

Therefore , the solution of the given problem of equation comes out to be he can hire the shoes for three hours with his meagre $11 budget.

Complex algorithms frequently employ a variable term to guarantee congruence with the two opposing assertions. Equations, which are academic expressions, are used to demonstrate the equality of different academic figures. In this instance, the normalise method provides b + 6 rather than merely expression separating 12 into two pieces for using the data from y + 6.

Here,

To begin, we can construct an expression to symbolise the circumstance:

=> y = 2x + 4

where x represents the number of hours that Quentin rents the shoes for and y represents the overall cost of the rental.

We can put y equal to 11 because we know that Quentin only has $11 to spend:

=> 11 = 2x + 4

We can now determine x:

=> 2x = 11 - 4

=> 2x = 7

=> x = 7/2

Quentin can therefore spend $11 to hire the shoes for 3.5 hours (7/2 hours).

He would have to pay either $10 or $12 to hire the shoes for either three or four hours. He can hire the shoes for three hours with his meagre $11 budget.

The length of arc EG is approximately 7.35 units.

To find the length of arc EG, we need to use the formula:

length of arc = (central angle/360°) × 2πr

where r is the radius of the circle and the central angle is in degrees.

We are given that m∠EFG = 58°, and EF = 6 units. Since EF is a chord of the circle, we can use the chord-chord angle theorem to find that m∠EGF = ½(180° - 58°) = 61°.

Now, we can use the Law of Cosines to find the length of GE:

GE² = EF² + FG² - 2(EF)(FG)cos(∠EGF)

GE² = 6² + FG² - 2(6)(FG)cos(61°)

Since FG = 2r (because it is the diameter of the circle),

GE² = 36 + (2r)² - 12r cos(61°)

We can simplify this to:

GE² = 4r² - 12r cos(61°) + 36

GE² = 4(r² - 3r cos(61°) + 9)

Now, we can use the formula for the length of the arc:

length of arc EG = (m∠EGF/360°) × 2πr

length of arc EG = (61/360) × 2πr

length of arc EG = (61/180) × πr

Substituting the expression for GE² in terms of r, we get:

length of arc EG = (61/180) × π √[4(r² - 3r cos(61°) + 9)]

We can now use a calculator to find the approximate value of the length of arc EG.

Rounded to the nearest hundredth, the length of arc EG is approximately 7.35 units.
