The surface area of a cylinder can be calculated as the sum of the area of the two circular bases and the lateral surface area, which is the area of a rectangle with length equal to the circumference of the base and width equal to the height of the cylinder.

The formula for the surface area of a cylinder is:

[tex]$A = 2\pi r^2 + 2\pi rh$[/tex], where $r$ is the radius and $h$ is the height.

In this case, we know that the radius is 3 inches and the surface area is square inches. To find the height of the cylinder, we can rearrange the formula to solve for $h$:

[tex]$A = 2\pi \cdot 3^2 + 2\pi \cdot 3h = 18\pi + 6\pi h$[/tex]

Dividing both sides by [tex]$6\pi$:[/tex]

[tex]$3 + h = \frac{A}{6\pi}$[/tex]

So, the height of the cylinder in inches is[tex]$h = \frac{A}{6\pi} - 3$.[/tex]

The solution is, the Bank of Peace will pay Marco more in interest over the 3-year period, Marco should choose the Bank of Peace to get the most interest, the total amount of interest that Marco will earn from the Bank of Trust over the 3-year period is, = £870.

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

here, we have,

To determine which bank will give Marco the most interest over the 3-year period, we need to calculate the total amount of interest that each bank will pay Marco over the 3 years.

First, let's consider the Bank of Peace.

Since the interest rate is 2.5% per year and is compounded annually, Marco will earn 2.5/100 * £15000 = £375 in interest in the first year. In the second year, the interest will be calculated on the original £15000 plus the £375 of interest earned in the first year, for a total of £15000 + £375 = £15375.

So Marco will earn 2.5/100 * £15375 = £383.44 in interest in the second year. In the third year, the interest will be calculated on the original £15000 plus the £375 of interest earned in the first year and the £383.44 of interest earned in the second year, for a total of

£15000 + £375 + £383.44 = £15728.44.

So Marco will earn 2.5/100 * £15728.44 = £391.71 in interest in the third year.

Therefore, the total amount of interest that Marco will earn from the Bank of Peace over the 3-year period is £375 + £383.44 + £391.71 = £1150.15.

Now let's consider the Bank of Trust. In the first year, Marco will earn 3.8/100 * £15000 = £570 in interest.

In the second year, the interest rate is 1%, so Marco will earn 1/100 * £15000 = £150 in interest. In the third year, Marco will also earn £150 in interest.

Therefore, the total amount of interest that Marco will earn from the Bank of Trust over the 3-year period is £570 + £150 + £150 = £870.

The perimeter of the triangle is given by the equation P = 42.588 m

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the perimeter of the triangle be represented as P

Let the right triangle be represented as ABC

Now , the hypotenuse of the triangle is AC = 18m

And , the measure of ∠ACB = 30°

From the trigonometric relations ,

Let the angle be θ , such that

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin 30° = AB / 18

On simplifying the equation , we get

Multiply by 18 on both sides of the equation , we get

sin 30° = 1/2

AB = 18/2

The opposite side of the triangle AB = 9 m

Now , the base of the triangle BC is calculated from Pythagoras theorem

hypotenuse² = base² + height²

So , base BC² = ( 18 )² - ( 9 )²

The base of the triangle BC = √ ( 324 - 81 )

The base of the triangle BC = 15.588 m

Now , the perimeter of the triangle P = opposite side of the triangle AB + base of the triangle BC + hypotenuse of the triangle AC

The perimeter of the triangle P = 18 + 9 + 15.588

The perimeter of the triangle P = 42.588 m

Hence , the perimeter of the triangle is 42.588 m

Step-by-step explanation:

The experimental probability that Dave works will be in a wedding in next week is 7 / 22.

Actual experiments and sufficient documentation of the occurrence of occurrences serve as the foundation for experimental probability, sometimes referred to as empirical probability. A number of real experiments are carried out in order to ascertain the likelihood of any event. Random experiments are studies that don't have a predetermined outcome. The results of such experiments are unpredictable. The likelihood of random experiments is calculated repeatedly. A trial is a repeating of an experiment that is performed a certain number of times.

The probability that Dave will work in a wedding is given as:

P = Working in wedding / Sum of total work

P = 14 / 44

P = 7 / 22

Hence, the experimental probability that Dave works will be in a wedding in next week is 7 / 22.

The correct answer is B) an equation of the best-fit line of data can be used to estimate untested values.

The equation of the best-fit line of data can be calculated by determining the slope (m) and the y-intercept (b) of the line. It is calculated by using the linear regression equation: y = mx + b, where m is the slope and b is the y-intercept. The slope is determined by the equation: m = (Σxy)/(Σx2). The y-intercept is determined by the equation: b = (Σy - mΣx)/n. Once these values are determined, it is possible to estimate untested values with the equation of the best-fit line. For example, if we have a graph with data points (2, 3) and (4, 7), the equation of the best-fit line would be y = 2x + 1. This equation can be used to estimate the value of y when x = 6; in this case, y = 11.

The probability of rolling two sixes is 1/25.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given, the probability of rolling a 6 on a biased dice is 1/5.

Since the probability of rolling a six on the first roll is 1/5, then probability of not rolling a six on first roll is;

P(not 6) = 1 - 1/5

P(not 6) = 4/5

A) Please find attached the completed tree diagram

B) First Roll:

P(6) = 1/5

P(not 6) = 4/5

Second Roll:

Now,

P(6 | 6) = 1/5 × 1/5

= 1/25

P(6 | not 6) = 1/5 × 4/5

= 4/25

So, P(not 6 | 6) = 4/5 × 1/5
