Question:

Luke is designing a scale model of a clock tower. the design of the front of the tower is shown below. what will be the area of the front face of his model?

(a) 2,500 square millimeters

(b) 10,000 square millimeters

(c) 12,500 square millimeters

(c) 15,000 square millimeters

The height of the tower is given as 200 mm and the width of the tower is 50 mm

Answer:

The correct option is;

(b) 10,000 square millimeters

Step-by-step explanation:

With the given dimension of the tower, Te front face of the tower is rectangular in shape.

Therefore, we have;

Area of a rectangle = Base Length × Height

Where:

Base length of the tower = 50 mm

Height of the tower = 200 mm

Therefore, area of the rectangular tower is therefore,

Area of a rectangle tower = Base length of the tower × Height of the tower

= 50 mm × 200 mm = 10000 mm².

Area of a rectangle tower = 10000 mm².

Darren wants to estimate the mean age in a population of trees. He'll sample nnn trees and build a 90\%90%90, percent confidence

Alchen [17]

Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

The margin of error is given by:

$M = z\frac{\sigma}{\sqrt{n}}$

In this problem, we have that the parameters are given as follows:

$M = 3, z = 1.645, \sigma = 16$ .

Hence, solving for n, we find the sample size.

$M = z\frac{\sigma}{\sqrt{n}}$

$3 = 1.645\frac{16}{\sqrt{n}}$

$3\sqrt{n} = 1.645 \times 16$

$\sqrt{n} = \frac{1.645 \times 16}{3}$

$(\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2$

$n = 76.97$

Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.

Anvisha [2.4K]

6.5 because you instantly take $9.50 away from $55. After you get that answer, you will have 45.5. Then divide 45.5 by 7 which will give you 6 and a half hours.
