A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The amount of paint needed to paint 20 pillars is 9.874 gallons.

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

The curved surface area of a single-cylinder with a diameter of 2.5 feet and a height of 22 feet will be,

Curved surface area = πDh = π × 2.5 × 22 = 172.7875 ft²

The total area of 20 pillar = 20 × 172.7875 ft² = 3,455.75191 ft²

Since a gallon of paint can cover only 350 ft², therefore, the amount of paint that will be needed to paint 3,455.75191 ft² can be written as,

[tex]\text{Amount of paint needed} = \dfrac{3,455.75191\rm\ ft^2}{350\rm\ ft^2} = 9.874\rm\ gallons[/tex]

Hence, the amount of paint needed to paint 20 pillars is 9.874 gallons.

The rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

Let's suppose the rate of the current  = r

The time it takes to go downstream + 4 hours   = time to go upstream

As we know the:

[tex]\rm Time = \dfrac{Distance}{ Rate }[/tex]

Now,

[tex]\rm \dfrac{44}{ (8 + r)} + 3 = \dfrac{44}{ (8 - r)}[/tex]

After solving:

[tex]\rm \dfrac{44}{ (8 - r)}-\dfrac{44}{ (8 + r)} =3[/tex]

After cross multiplication

44(8+r) - 44(8-r) = 3(8+r)(8-r)

88r = 3(64 - r²)

3r² + 88r - 192 = 0

After solving the above quadratic equation, we get:

r = 2.03 or

r=−31.37 (reject as it is negative)

So, the r  =2.03 mph

Thus, the rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.

Using the dot plot concept, it is found that the left plot on the bottom row shows an unfair data-generating process.

The dot plot shows the number of times each measure appears in the data-set.

In this problem, each trial has 5 possible outcomes and there are 20 trials, hence each number should appear 20/5 = 4 times.

On the left plot of the bottom row, outcomes 1 and 5 appear 7 times, while outcomes 2, 3 and 4 appear 2 times, which are the furthest values from 5, hence it is an unfair data-generating process.

Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.

The distribution for the number of honors classes the school offers is given by:

Hence the probability of an even number is given by:

P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.

Answer:

0.17

Step-by-step explanation:

The probability for purchasing 2 tickets at a time can be given as 0.17. The correct option is (A).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

Suppose X be the event to represent the number of tickets in purchase.

Then,  as per the question distribution table can be formed as follows,

The number of tickets (X)                                 P(X) Probability

            1                                                                      0.17

            2                                                                     0.55

            3                                                                     0.20

            4                                                                     0.06

            5                                                                     0.02

Thus, the probability of selecting less than two tickets can be obtained as,

P(X < 2) = P(X = 1)

⇒ 0.17

Hence, the probability for a purchase to have less than two tickets is given as 0.17.

The equation for the translation of y = 5/x is y = 5/(x+7) + 7 if that has the asymptotes x= -7 and y= 7

It is a curve in two-dimensional geometry having two parts, they both are symmetric. In other words, It can be defined as the number of points in the two-dimensional geometry that have a constant difference from that point to two fixed points in the plane.

We have:

[tex]\rm y = \dfrac{5}{x}[/tex]

Vertical asymptotes x= -7 and

Horizontal asymptotes y= 7

After translation:

[tex]\rm y = \dfrac{5}{x+7}+7[/tex]

The maximum number of tourists in the third week will be maximum in the numberville city.The solution of f(x)=h(x) will be x(5,2).

The equation is actually a relationship between the numbers and the variables.

To calculate the number of the tourists in the third week we will put the value 3 in every function:

[tex]f(x)=x^2+5x+10=(3)^2+(3\times 3)+10=29\\\\\\g(x)=3^x=3^3=27\\\\\\h(x)=10x=10\times 3=30[/tex]

So we can see that the function third h(x) numberville city is having a maximum number of tourists.

The solution of f(x)=h(x) will be calculated as:

[tex]x^2-3x+10=10x\\\\\\x^2-7x+10=0\\\\\\x^2-5x-2x+10=0\\\\\\x(x-5)-2(x-5)=0\\\\\\x=5,2[/tex]

Hence the solution of f(x)=h(x) will be x(5,2).
