Step-by-step explanation:
A random sample of the 900 passengers boarding a plane was asked if they had ever flown before.
Have flown before: 32 Have not flown before:18
Write a proportion that can be used to determine how many passengers have probably not flown before.
324 passengers
Step-by-step explanation:Total number of passengers that were boarding the plane = 900
Part of ratio of people who have flown a flight before = 32
Part of ratio of people who have not flown a flight before = 18
Ratio of the people who has flown to who has not flown a flight = 32 : 18
Sum of both the parts of ratio = 32 + 18
= 50
Total number of people who has flown a flight before = 32/50 * 900
= 576 people
Total number of people who has not flown a flight before = 18/50 * 900
= 324 people
Proportion = 32 : 18 :: 576 : 324
Hence, the number of people who has not flown a flight before is 324.

Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The square has a side length of 3 ft
Area of the base is 3×3
Area of the base is 9 square feet
Now let us find the lateral face area = 2a√[(a²/4) + h²]
=2(3)√[(9/4) + 17.64]
=6√20
=27 square feet
Lateral surface area = a√(a²+4h²)
a=3, h=4.2
Lateral surface area = 3√(9+4(4.2)²)
= 3√(9+4(17.64))
3√(9+70.56
= 3√79.56
=3×9
=27 square feet
To find total surface area, we have to find the slant height by pythagoras theorem
(1.5)²+(4.2)²=l²
2.25+17.64=l²
20=l²
4.47=l
Now total surface area = a² + 2al
=3²+2(3)(4.47)
=9+26.82
=36 square feet
Hence, Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.

Use the value 3.14 for π, and do not do any rounding.
Be sure to include the correct unit in your answer.
Answer:
113.04
Step-by-step explanation:
To find the volume of a cone use the formula [tex]1/3 \pi r^2h[/tex].
The formula would be [tex]1/3*3.14* 3^2*12[/tex]

Complete the chart in model it on the previous page. Describe and explain the relationship between the decimals for 2/6 and 4/6
Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.
When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.

Answer:
The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
step by step:
From the number line we can observed that:
1) A, B, C and D lies between -1 and 0.
2) Point A and B lies between -1 and -0.5
3) Point C and D lies between -0.5 and 0
Therefore, the value of A and B must have a negative value lying between -1 and -0.5
Also, the value of C and D must have a negative value lying between -0.5 and 0.
Now consider the provided options.
Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16
This is Incorrect representation because the value of A and B should lying between -1 and -0.5.
Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.
Also they are in ascending order from -1 to 0.
Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Solve the following equations.
1.) 1/5x - 2 = -3
2.) 15 = 10 - x/4
3.) x/3 - 12 = -2
4.) x/-2 + (-6) = 6
Answer:
-5-2030-24Step-by-step explanation:
Solve the following equations.
1.) 1/5x - 2 = -3
2.) 15 = 10 - x/4
3.) x/3 - 12 = -2
4.) x/-2 + (-6) = 6
1/5x - 2 = -3
1/5x = -1
x = -1 : 1/5
x = -1 × 5
x = -5
15 = 10 - x/4
5 = -x/4
x = -5 : 1/4
x = -5 × 4
x = -20
x/3 - 12 = -2
x/3 = 10
x = 10 × 3
x = 30
x/-2 + (-6) = 6
x/-2 - 6 = 6
x/-2 = 12
x = -24

The height of the dead tree is 16 feet
The direction in which the tree should fall is Northeast, Northwest, Southeast, Southwest.
How to solveFrom the given question, since the ray is straight, AC is parallel to DF
Meanwhile triangles ABC and DEF are right angles,
AB/DE =BC/EF
AB/6 = 8/3
AB= 16 feet.
Thus, the height of the tree is 16 feet.
Since 16 ft> 15ft> 14ft> 13ft> 12ft
Therefore, the direction which the tree is falling is Northeast, Northwest, Southeast, Southwest.

Students were surveyed to determine their favorite types of animals. The bar graph shows the number of students who selected each type of animal. 80% 5% 6% Type of Animal 20% Fish Lizard Bird 6 8 Number of Students What percentage of the students surveyed selected "Bird" as their favorite type of animal? Dog Cat 10 2 Favorite Animals 10
20% of the students surveyed selected "Bird" as their favorite type of animal. Hence option D is correct.
What is the percentage of Bird?To calculate the percentage of students who selected "Bird" as their favorite type of animal, we need to first determine the total number of students surveyed. From the bar graph, we can see that the total number of students is:
2 + 4 + 6 + 10 + 8 = 30
The number of students who selected "Bird" as their favorite type of animal is 6. To calculate the percentage, we can use the following formula:
Percentage = (Number of students who selected "Bird" / Total number of students surveyed) x 100%
Substituting the values we have:
Percentage = (6 / 30) x 100%
Percentage = 20%
Therefore, 20% of the students surveyed selected "Bird" as their favorite type of animal.
