What is the sample? all state households 1565 households surveyed 1127 households that owned televisions.
The percentage of the household survey that owned televisions is 72%. And the sample is defined below.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
What is a sample?Random sampling is the method of selecting the subset from the set to make a statical inference.
All states households 1565 households surveyed 1127 households that owned televisions. Then the percentage will be
[tex]\rm Percentage = \dfrac{1127}{1565}*100\\\\Percentage = 0.72*100\\\\Percentage = 72 \%[/tex]

Answer: Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
To find the perimeter of this quadrilateral with known vertices: Use the distance formula to find the length of each side, and then add the lengths.
What is distance?The distance between two points is the length of the line joining the two points. Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
Here, we have,
Mathematically, the distance between points on a coordinate plane is given by this formula:
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
Where:
x and y are the vertices (points) on a coordinate plane.
Therefore, when the distance formula has been used to determine the length of of each side of the quadrilateral. You should then add the lengths of each side together.

This one is about rate of change and has 2 questions that need two answers.
At 6:00 am, there was 1 inch of snow on the ground. By 11 am, there were 4 inches of snow on the ground. What is the average rate of change?
If the snow continues to fall at the same rate, how much snow will be on the ground by 1:00 pm.
Answer:
0.6 inches per hours
5.2 inches on the ground by 1:00 pm
Step-by-step explanation:
Let x = number of hours after midnight
Let y = height of snow (in inches)
Information presented as ordered pairs (x, y):
(6, 1)
(11, 4)
[tex]\mathsf{rate \ of \ change=\dfrac{change \ in \ y}{change \ in \ x}=\dfrac{4-1}{11-6}=\dfrac35 \ inches \ per \ hour}[/tex]
Written as a linear equation:
[tex]y-1=\dfrac35(x-6)[/tex]
[tex]\implies y=\dfrac35x-\dfrac{13}{5}[/tex]
1:00 pm = 13 hours after midnight
Therefore, when x = 13:
[tex]\implies y=\dfrac35(13)-\dfrac{13}{5}[/tex]
[tex]\implies y=5.2 \textsf{ inches}[/tex]
What is the median of the following dataset? (1,5,6,3,4,5,6,8,9)
Answer:
The median would be the second 5
Therefore our answer would be 5
Step-by-step explanation:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory

Answer: Below
Step-by-step explanation:
Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.
Let's use E for Elena, J for Jada, and L for Lin.
E + 4 = J
E + 6 = L
E = E
We know they all walked a total of 37 miles.
J + L + E = 37
(E + 4) + (E + 6) + E = 37
Simplify.
3E + 10 = 37
3E = 27
E = 9
Using E is 9, we find that:
Elena walked 9 miles
Lin walked 15 miles
Jana walked 13 miles
13 + 15 + 9 = 37, so our answer checks out.
We know that:
[tex]Jada + Elena + Lin = 37 \space\ miles[/tex][tex]Jada = 4 + Elena[/tex][tex]Lin = 2 + Jada[/tex]Finding the distance each walked:[tex]Jada + Elena + Lin = 37 \space\ miles[/tex]Add 4 both sides
=> [tex]Jada + Elena + 4 + Lin = 37 + 4[/tex]=> [tex]Jada + Jada + Lin = 41 \space\ miles[/tex] [tex][Jada = 4 + Elena][/tex]=> [tex]Jada + Jada + Jada + 2 = 41 \space\ miles[/tex] [tex][Lin = Jada + 2][/tex]Changing "Jada + Jada + Jada" to "3(Jada)"
=> [tex]3(Jada) + 2 = 41 \space\ miles[/tex]Subtracting 2 both sides:
=> [tex]3(Jada) = 41 - 2[/tex]=> [tex]3(Jada) = 39 \space\ miles[/tex]Divide 3 both sides:
=> [tex]3(Jada) = 39 \space\ miles[/tex]=> [tex]\frac{3(Jada)}{3} = \frac{39 \space\ miles}{3}[/tex]=> [tex]\bold{Jada} = \bold{13 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Jada = 4 + Elena"
[tex]Jada = 4 + Elena[/tex]=> [tex]13 = 4 + Elena[/tex]Subtract 4 both sides:
=> [tex]13 - 4 = 4 - 4 + Elena[/tex]=> [tex]\bold{Elena} = \bold{9 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Lin = 2 + Jada"
=> [tex]Lin = 2 + 13[/tex]=> [tex]\bold{Lin} = \bold{15 \space\ miles}[/tex]

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. 'When the
rock is cut in half, what is the volume and density of each piece?
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Step-by-step explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³

A company figured it needed 68. 5 square feet of carpet for its reception room. To allow for waste, it was decided to order 40 percent more material than needed. Fractional parts of square feet cannot be ordered. At $8. 00 per square foot, how much would the carpet cost?
The total cost of the carpet purchased by the company for its reception is $767.20.
What is the total cost of the carpet?The first step is to determine the total square feet of carpet that would be bought: 1.40 x 68.5 = 95.9 square feet
Now, determine the total cost of the carpet. This can be known by multiplyig the cost per square foot by the total amount of carpet needed.
95.9 x 8 = $767.20

Given: m∠ABC = m∠CBD Prove: Ray B C bisects ∠ABD. 3 lines extend from point B. One line extends to point A, another to C, and another to D. Justify each step in the flowchart proof. A flow chart with 3 boxes that are labeled A, B, C, from top to bottom. Box A contains m angle A B C = m angle C B D. Box B contains angle A B C is-congruent-to angle C B D. Box C contains Ray B C bisects angle A B D.
Answer:
Given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector)
Step-by-step explanation:
The given information are;
m∠ABC = m∠CBD
To prove that Ray BC bisects m∠ABD
The description is therefore;
Three lines (AB, BC, and BD) that meet at a point
The content of Box A = m∠ABC = m∠CBD
The content of Box B = m∠ABC ≅ m∠CBD
The content of Box C = Ray BC bisects m∠ABD
Therefore, we have;
m∠ABD = m∠ABC + m∠CBD (Angle addition postulate)
m∠ABC = m∠CBD (Given)
∴ m∠ABC ≅ m∠CBD (Definition of congruent angles)
m∠ABC is adjacent to m∠CBD (Description of the angles)
Line BC is common to m∠ABC and m∠CBD (Description of the angles)
Therefore, given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector).

Step-by-step explanation:
[tex]16 {}^{x} = \frac{1}{64} [/tex]
[tex]4 {}^{2x} = 4 {}^{ - 3} [/tex]
[tex]2x = - 3[/tex]
[tex]x = - \frac{3}{2} [/tex]
Answer:
x = -3/2
Step-by-step explanation:
We make both numbers have the same bases.
We know 2^4 = 16 and 2^-6 = 1/64 because a negative exponent means you get the reciprocal of the number.
2^4x = 2^-6
Let exponents equal each other.
4x = -6
x = 6/4 = -3/2
x = -3/2
