There are 3 groups of 11 travellers each or 11 groups of 3 travellers each.

Since we have 33 travellers and we need to divide them into equal sized groups, we need to find the factors of 33.

So, 33 = 1 × 33 = 3 × 11

So, the two factors of 33 we require are 3 and 11.

Since 11 × 3 = 3 × 11,

So, 3 × 11 implies that we can have 3 groups of 11 travellers each and,

11 × 3 implies that we can have 11 groups of 3 travellers each.

So, there are 3 groups of 11 travellers each or 11 groups of 3 travellers each.

Answer:

60 minutes

Step-by-step explanation:

Latitude and longitude are measuring lines used for locating places on the surface of the Earth. They are angular measurements, expressed as degrees of a circle. A full circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.

One degree of latitude is equal to approximately 60 nautical miles or 69 statute miles. Since a minute of latitude is one-sixtieth of a degree, it follows that one degree of latitude is equal to 60 minutes.

This means that there are 60 nautical miles or 69 statute miles between two points that differ by one minute of latitude.

The minute of latitude is a widely used unit for measuring distances on Earth, particularly in navigation and aviation. It allows for precise calculations and is crucial for determining positions accurately. Understanding the relationship between degrees of latitude and minutes helps in determining distances, estimating travel times, and ensuring accurate navigation across the globe.

Answer:

A: 1,590.00

Step-by-step explanation:

We can use the simple interest rate equation for this problem: p(1 + r)^t

Step 1: Replace the variables with the amounts given

10000(1 + 0.03)^5

Step 2: Solve/Plug in calc

You will get 1590.00

A) The sample proportion = 0.17, and standard error/deviation = 0.013281

B) 0.869

C)0.9668

A) We know that 17% of households spend more than $100 per week on groceries. We are given that p ( the proportion of the population that spends more than $100 per week) = 0.17

sample size (n)= 800

The sample proportion of p = 0.17

The standard error of p will be calculated using this formula =

\(\sqrt{\frac{p(1-p)}{n} }\) =\(\sqrt{\frac{0.17(1 - 0.17)}{800} }\)

=  0.013281

B) We have to find the probability that the sample proportion will be +-0.02 of the population proportion

= p (0.17 - 0.02 ≤ P ≤ 0.17 + 0.02 ) = p( 0.15 ≤ P ≤ 0.19)

z value corresponding to P

Z = (P - p)/std deviation at P = 0.15

Z =  (0.15 - 0.17) / 0.013281 =  -1.51

at P = 0.19

z = ( 0.19 - 0.17) / 0.013281 = 1.51

Therefore the required probability will be

p( -1.5 ≤ z ≤ 1.5 ) = p(z ≤ 1.51 ) - p(z ≤ -1.51 )

= 0.9345 - 0.0655 = 0.869

C) Now, we have to find the same probability for a sample (n ) = 1600

standard deviation/ error = 0.009391 (applying the equation for calculating standard error as seen in part A above)

Therefore the required probability after applying;

z =   (P - p)/std deviation at p = 0.15 and p = 0.19

p ( -2.13 ≤ z ≤ 2.13 ) = p( z ≤ 2.13 ) - p( z ≤ -2.13 )

= 0.9834 - 0.0166 = 0.9668

Therefore,

A) The sample proportion = 0.17, and standard error/deviation = 0.013281

Therefore, the volume of the irregular solid in the fourth image is 243 cubic meters.

Volume is a measure of the amount of space occupied by a three-dimensional object or solid. It is usually expressed in cubic units such as cubic centimeters (cm³), cubic meters (m³), or cubic feet (ft³). The formula for finding the volume of a regular solid depends on its shape. For example, the volume of a cube is found by cubing the length of one of its sides, while the volume of a cylinder is found by multiplying the area of its base by its height.

Here,

1. To find the area of the irregular shape in the first image, we can divide it into two rectangles and one right triangle, as shown below:

+--------+ 4 cm

|        |

|        |

+--------+

   2 cm

   5 cm

+--------+

|        |

|        |

+--------+

   2 cm

The area of the shape is then the sum of the areas of these smaller shapes:

Area = (4 cm x 2 cm) + (5 cm x 2 cm) + (1/2 x 5 cm x 2 cm)

= 8 cm² + 10 cm² + 5 cm²

= 23 cm²

Therefore, the area of the irregular shape in the first image is 23 cm².

2. To find the area of the irregular shape in the second image, we can divide it into two triangles and one parallelogram, as shown below:

+-----------------+

|        /        |

|    5 /          | 2 cm

|    /            |

|  /              |

+-----------------+

      5 cm

The area of the shape is then the sum of the areas of these smaller shapes:

Area = (1/2 x 5 cm x 5 cm) + (1/2 x 5 cm x 2 cm) + (5 cm x 2 cm)

= 12.5 cm² + 5 cm² + 10 cm²

= 27.5 cm²

Therefore, the area of the irregular shape in the second image is 27.5 cm².

3. To find the volume of the irregular solid in the third image, we can use the formula V = L x W x H, where L is the length, W is the width, and H is the height.

V = 6 ft x 25 ft x 16 ft

= 2400 cubic feet

Therefore, the volume of the irregular solid in the third image is 2400 cubic feet.

4. To find the volume of the irregular solid in the fourth image, we can divide it into a rectangular prism and a pyramid, as shown below:

+-----------------+

|                 |

|   +---------+   | 3 m

|   |         |   |

|   |         |   | 1 m

|   +---------+   |

|                 |

+-----------------+

    4 m   19 m

The volume of the rectangular prism is V1 = L x W x H

= 4 m x 19 m x 3 m

= 228 cubic meters.

The volume of the pyramid is V2 = (1/3) x B x H, where B is the base area and H is the height of the pyramid. We can find the base area by multiplying the length and width of the rectangle:

B = L x W

= 5 m x 3 m

= 15 square meters

The height of the pyramid is the same as the height of the rectangular prism:

H = 3 m

Therefore, the volume of the pyramid is V2 = (1/3) x 15 square meters x 3 m

= 15 cubic meters.

The total volume of the irregular solid is then the sum of the volumes of the rectangular prism and the pyramid:

V = V1 + V2

= 228 cubic meters + 15 cubic meters

= 243 cubic meters

Therefore, the volume of the irregular solid in the fourth image is 243 cubic meters.

6. When an irregular shape has a complex or irregular form, one way to find its area or volume is by breaking it down into smaller shapes or solids that are easier to calculate. By dividing the irregular shape into smaller, regular shapes, we can add up the individual areas or volumes to get the total area or volume of the larger shape or solid. This method is commonly used when working with irregular shapes in geometry, as well as with complex solids in calculus and physics.

The production cost of company 1 is higher than company 2, and when producing the same number of units, company 2 has a lower production cost than company 1. This indicates that when producing the same number of units, company 2 has a lower production cost than company 1.

The given function represents the production cost f(x), in dollars, for x number of units produced by company 1:f(x) = 0.25x² − 8x + 600

The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:x     g(x)6     862.28     856.810   85512   856.814   862.2

To determine whether the production cost of company 1 is less than the production cost of company 2 when producing the same number of units, we must find the production cost of both companies for each given value of x and then compare them. Using the formula above, the production cost of company 1 for each given value of x is:

f(6) = 0.25(6)² − 8(6) + 600= 81 dollars

f(8) = 0.25(8)² − 8(8) + 600= 88 dollars

f(10) = 0.25(10)² − 8(10) + 600= 95 dollars

f(12) = 0.25(12)² − 8(12) + 600= 100 dollars

f(14) = 0.25(14)² − 8(14) + 600= 103 dollars

The production costs of company 2, which are given in the table, are:g(6) = 862.2 dollars

g(8) = 856.8 dollars

g(10) = 855 dollars

g(12) = 856.8 dollars

g(14) = 862.2 dollars

We can see that for each value of x, the production cost of company 1 is higher than the production cost of company 2. Therefore, when producing the same number of units, the production cost of company 2 is less than the production cost of company 1.

The standard error of the proportion decreases as the sample size increases. This means that larger sample sizes provide more accurate estimates of the population proportion.

To calculate the standard error of the proportion, we can use the formula:
SE = √(p(1-p)/n)
Where:
SE = standard error
p = proportion of the population
n = sample size
For each sample size, we can plug in the values and calculate the standard error:
A. For a sample size of 30:
SE = √(0.39(1-0.39)/30) = 0.088
B. For a sample size of 60:
SE = √(0.39(1-0.39)/60) = 0.062

x + 10y = 163

x+y = 55

x = 55 - y

x + 10y = 163

(55-y) + 10y =163

55 - y + 10y = 163

The value of the unknown variable in the ordered pair is 8

From the question, we have the following ordered pairs that can be used in our computation:

(r, 3), (5, 9)

Also, we have

m = 2

The meaning of the above notations are

Ordered pairs (x, y) = (r, 3), (5, 9)

Slope, m = 2

The slope of points is calculated using the following slope equation

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (r, 3), (5, 9) and m = 2

Substitute the known values in the above equation, so, we have the following representation

(9 - 3)/(r - 5) = 2

Since both sides of the equation are equal, we have completed the basic step of the proof, showing that P(1) is true.

a.) The statement P(1) is obtained by substituting n=1 into the equation. So, P(1) would be: 1³ = (1(1 + 1) / 2)²

b.) To show that P(1) is true, we need to prove that both sides of the equation are equal:

Left side: 1³ = 1

Right side: (1(1 + 1) / 2)² = (1(2) / 2)² = (2 / 2)² = 1² = 1
