Answer:
Option D is correct.
A voluntary response error was made in this design. This type of sampling only targets those who are passionate about a specific act and call in to vote; it is not a good representation of the population.
Step-by-step explanation:
When humans are given the choice whether to participate in a survey like in this question, most often than not, the survey becomes biased.
This is because only the people or set of people who feel strongly the most about the subject matter of the poll will participate in the survey. This favours the group that disagrees as this group, if given the choice to express their opinion, will most likely be the set of people that will readily express their discontent.
Discontent is more visibly and strongly expressed in humans.
In order to remove this bias, people should have been chosen at random and their responses recorded.

Determine the measure of the interior angle at vertex D.
Answer:
162°
Step-by-step explanation:
This is a hexagon, so the sum of the angle measures will be 720°
Add up the measures
40x=720
Divide
X=18
Multiply by 9 to find angle of D
9*18=162
The measure of the interior angle at vertex D is 162°. Hence, option B. is the right choice.
What are polygons?Polygons are closed plane figures formed by the intersection of 3 or more non-collinear line segments.
What is the sum of all interior angles of a polygon?The sum of interior angles of an n side polygon = (n-2)180°.
How do we solve the given question?We are given a 6 side polygon ABCDEF.
∴ n = 2.
The sum of interior angles of polygon ABCDEF = (6-2)180° = 4*180° = 720°.
The angles are 2x, 9x, 2x, 9x, 9x, and 9x.
Their sum = 2x + 9x + 2x + 9x + 9x + 9x = 40x.
This sum = The obtained sum
or, 40x = 720°
or, x = 720°/40 = 18°.
∴ Interior angle at vertex D = 9x = 9*18° = 162°. Hence, option B. is the right choice.

Find the value of x in the following
a) x:2 = 10:4 b) 3:x= 6:8
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) x:2 = 10:4
Product of extremes = Product of means
=> x*4 = 10*2
=> 4x = 20
Dividing both sides by 4
=> x = 5
b) 3:x = 6:8
Product of extremes = Product of Means
=> 3*8 = 6*x
=> 24 = 6x
Dividing both sides by 6
=> x = 4
Answer:
a. X= 5b. X= 4Solution,

Possible values for the area A of the rectangle shown are 12 ≤ A ≤ 36. Write and solve a compound inequality to find the possible values of x. Are these values all viable in this situation?I really need help
Answer:
x can take any value and are viable in this situation if and only if it is a positive number
Step-by-step explanation:
We know that the area of a rectangle is given by:
A = x * y
So if we replace we have:
12 ≤ x * y ≤ 36
We divide by y, and we have:
12 / y ≤ x ≤ 36 / y
Which means that the value of x depends on y, that is to say if y is worth 1, the inequality would be:
12 ≤ x ≤ 36
In the event that y is equal to 2:
12/2 ≤ x ≤ 36/2
6 ≤ x ≤ 18
Which means, that depending on y, x can take any value and are viable in this situation if and only if it is a positive number.

For a rectangle of length L and width W, the area is given by:
A = L*W
We will find that the solution is: 3/2 ≤ x ≤ 11/2
Here we have:
L = 3
W = 2x + 1
Then the area equation is:
A = 3*(2x + 1) = 6x + 3
And we also have the inequality:
12 ≤ A ≤ 36
Replacing A with the equation we get:
12 ≤ 6x + 3 ≤ 36
Now we solve this for x:
12 - 3 ≤ 6x ≤ 36 - 3
9 ≤ 6x ≤ 33
Now we divide both sides by 6.
9/6 ≤ x ≤ 33/6
3/2 ≤ x ≤ 11/2

I need this ASAP! When David was asked how old he was, he said: "I'm three times younger than my dad, but twice as old as Rebecca." Then little Rebecca ran up to him and declared "I am 30 years younger than my dad." How old is David?
Answer:
David is 12 years old.
Step-by-step explanation:
Let r = Rebecca's age
Let d = David's age
let p = Dad's age
David is 3 times as younger than his dad:
d = [tex]\frac{p}{3}[/tex]
David is 2 times older than Rebecca:
d = 2r
Rebecca is 30 years younger than the dad:
r = p-30
All three equations can be solved by a system
2r = [tex]\frac{p}{3}[/tex]
r = p-30
multiplying r = p-30 by negative 2 and adding it to 2r = [tex]\frac{p}{3}[/tex]
0 = (-2p + p/3) + 60
multiplying new equation by 3
0 = (-6p + p) + 180
5p = 180
p = 36
d = 36/3 = 12

Work out the surface area of this triangular prism
Answer:
1008 [tex]cm^2[/tex]
Step-by-step explanation:
Given:
Triangular prism with
Base of triangle = 5 + 9 = 14 cm
Height of triangle = 12 cm
Here, we have 3 faces of the prism as a rectangle, all have width = 20 cm
Lengths of faces = 13cm ,14cm and 15 cm respectively
To find:
Total surface area = ?
Solution:
3 faces are rectangular shape and 2 faces are triangular shape.
[tex]Area\ of\ rectangle = Length \times Width[/tex]
The formula for Total Surface Area of a triangular prism is given as:
[tex]TSA = 2 \times \text{Area of triangular base}+{\text{Area of rectangular faces}}\\\Rightarrow TSA = 2 \times \dfrac{1}{2}\times Base \times Height+{\text{Area of rectangular faces}}\\\Rightarrow TSA = 14 \times 12 + 15 \times 20+ 13 \times 20+ 14 \times 20\\\Rightarrow TSA = 168 + 840\\\Rightarrow TSA = 1008\ cm^2[/tex]
So, the total surface area of the given triangular prism is 1008 [tex]cm^2[/tex].

Answer:
SA = 144 cm².
Step-by-step explanation:
Find the surface area by calculating the areas of each of the lateral sides and bases:
In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:
Bases:
A = 1/2(bh)
A = 1/2(4·3)
A = 1/2(12)
A = 6 cm².
There are two bases, so:
6 × 2 = 12 cm²
Find the areas of the lateral sides using A = l × w:
5 × 11 = 55 cm²
4 × 11 = 44 cm²
3 × 11 = 33 cm²
Add up all of the areas:
12 + 55 + 44 + 33 = 144 cm².
Answer:
144 cm^2
Step-by-step explanation:
So, first find the area of the triangle. To find that you need to use the formula A = bh ÷ 2 (Area = base x height ÷ 2)
A = (4)(3) ÷ 2
A of triangle = 6
Since there are 2 triangles, you need to multiply the area by 2, which equals 12.
To find the area of the rectangles, you need to use the formula A = lw (Area = length x width)
For the first rectangle,
A = 11 x 5
A = 55
For the second rectangle,
A = 4 x 11
A = 44
For the third rectangle,
A = 3 x 11
A = 33
Now, you need to add the areas of the triangles and rectangles together to get your surface area.
12 + 55 + 44 + 33 = 144cm^2
So, the surface area of the triangular prism is 144 cm^2.
According to a nutrition coach, a 100 kg person should eat
0.07 kg of protein. What percent of a person's body weight should they eat
in protein? (round to 2 decimal places) *
Answer:
0.07%
Step-by-step explanation:
This equation is solving for what percentage of 100 kg is 0.07 kg.
1. Set up the equation
[tex]\frac{0.07}{100}[/tex] = [tex]\frac{x}{100}[/tex]
0.07 kg out of 100 kg is equal to x out of 100 because x represents the percentage and percentages are out of 100.
2. Solve by cross multiplying
100x = 7
3. Solve for x by dividing both sides by 100
x = 0.07
The answer is 0.07%

What is the third quartile for this data set?
Answer:
38
Step-by-step explanation:
Using the five number summary it is 38 since it is 75 percent of the sample
You have the correct answer. Nice work
==========================================================
Explanation:
If the values aren't sorted, then list them from smallest to largest. The values are already sorted for us, so we move onto the next step.
That next step is to find the median. The median is 29 because four values are smaller than it, and four values are larger than it. The value 29 is right in the middle. This value is in slot 5.
Next, split the data into two halves where L = {21,24,25,28} is the lower half and U = {35,37,39,42} is the upper half. As you can see, any value in set L is smaller than the median. While any value in set U is larger than the median.
The third quartile is the median of set U. We have four values in this set, so the median will be between slots 3 and 4 (between 37 and 39)
Average 37 and 39 to get (37+39)/2 = 38. We see that 38 is the midpoint of 37 and 39.
Therefore, the third quartile is 38.

Answer:
x=70
z=20
y=30
Step-by-step explanation:
first find x: the sum of straight angle is 180
x+110=180
x=180-110=70
now find z: the sum of the angles of triangle is 180:
x=70, right angle=90
z+70+90=180
find y:
y+110+40=180
y=180-150=30
z=180-160=20
Answer:
x=70 degrees, y= 30 degrees, z=20 degrees
Step-by-step explanation:
110+x=180 => straight angle def.
180-110+40=y => def. of angles in triangle
x( 70 degrees) +90+z=180, z= 20 => angles in triangle
