13. A certain town with a population of 100,000 has 3 newspapers: I, II, and III. The proportions of townspeople who read these papers are as follows: I: 10 percent I and II: 8 percent I and II and III: 1 percent II: 30 percent I and III: 2 percent III: 5 percent II and III: 4 percent (The list tells us, for instance, that 8000 people read newspapers I and II.) Find the number of people who read only one newspaper. How many people read at least two newspapers
Answers
Answer:
a) the number of people who read only one newspaper is 20,000
b) number of people read at least two newspapers is 12,000
Step-by-step explanation:
Given the data in the question;
A certain town with a population of 100,000 has 3 newspapers
a)Find the number of people who read only one newspaper
From the Venn-diagram illustrating the data in the question;
Number of that read only one paper will be;
=[ ([tex]I^{}[/tex]∩ [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) ] × 100,000
= [ 1% + 19% + 0% ] × 100,00
= 20% × 100,000
= 20,000
Therefore, the number of people who read only one newspaper is 20,000
b) How many people read at least two newspapers;
Number of people read at least two newspapers will be;
= [ ([tex]I^{}[/tex]∩ [tex]II^{}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{}[/tex] ∩ [tex]II^{}[/tex] ∩ [tex]III^{}[/tex]) ] × 100,000
= ( 7% + 1 % + 3% + 1% ) 100,000
= 12% × 100,000
= 12,000
Therefore, number of people read at least two newspapers is 12,000

You are looking at a pair of parallel lines (a and b) and a transversal that crosses them both.
Now that you know what think back to when you learned the relationship between angles formed by a transversal and a set of parallel lines.
You can have same side exterior, same side interior, alternate interior and alternate exterior. Which set of these are these angles?
Remember same side interior and same side exterior angles are supplementary (they have a sum of 180 degrees). Alternate interior and alternate exterior angles are congruent. Knowing this how can an equation be written using the expressions in the image?
Step-by-step explanation:
Answer:
x = 3.4
Step-by-step explanation:
Since these two angles are opposite exterior angles, they are equivalent. that means that 5x - 2/3 = 3 1/3x + 5, from here you should simplify the terms so you have all of x on one side and all of the number on ther other, it should be 1 2/3x = 5 2/3, then all you have to do is divide both sides by 1 2/3 to get x which is 3.4 or 3 2/5

Answers
Answer:
2 pizzas
Step-by-step explanation:
2/5 of 5 is easy since there are 5
so 2 out of 5 is 2
Answer:
2 pizzas
Step-by-step explanation:
If there were 5 pizzas to begin with and only 2 out of that 5 were eaten, then that means they ate 2
0 0 0 0 0 pizzas started with
_ _ pizzas ate
0 0 0 pizzas left with
So if there were 3 pizzas left with, then you can subtract 3 from 5 to see how many are gone or eaten.

The NEC permits 20% of the cross sectional area in a wireway to be occupied by conductors.for an 8"×8"×6' long wireway the conductors can occupy. In squared?
Answers
Answer:
Step-by-step explanation:
Sjaoa
The required cross-sectional area in a wireway is 12.8 In squared.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have been given an 8"×8"×6' long wireway the conductors can occupy.
Since the NEC permits 20% of the cross-sectional area in a wireway to be occupied by conductors
So the required cross-sectional area in a wireway is
⇒ 20 % of ( 8"×8" )
⇒ 0.20 × (64 )
⇒ 12.8 In squared
Thus, the required cross-sectional area in a wireway is 12.8 In squared.

Isabella earned $48 from Nara. Isabella earned $16 from Hector. Isabella sells petunias for $6 per bunch (the number of petunias per bunch is unclear).
Step-by-step explanation:
Nala bought 12 roses which is greater than 10. So she received a $1 discount for each one. Nara spent 12*4=$48 dollars.
Hector bought 4 bunches of daisies meaning that Hector spent 4*4=$16.

A political scientist wants to estimate the percent of registered voters in Florida who plan to vote for a particular candidate. The political scientist interviews 4000 randomly selected registered voters in Florida and asks who they plan to vote for. 58% say they plan to vote for the candidate. Which of the following statements is true?
a. 58% is a parameter because it describes a population characteristic.
b. 58% is a statistic because it describes a sample characteristic.
c. 58% is a statistic because it describes a population characteristic.
d. 58% is a parameter because it describes a samic characteristic.
Answers
Answer:
b.) 58% is a statistic because it describes a sample characteristic.
Step-by-step explanation:
The randomly selected 4000 voters represents a randomly selected observations from the population of registered voters
Hence, 4000 is a sample.
The percentage of voters who would vote for a particular candidate represents a numerical characteristic derived from the sample drawn.
Recall that, numerical characteristics or values which are calculated from the sample is known as statistic while those derived from the population are called parameter.
Hence, 58% is a statistic as it describes a sample characteristic.
You can use definition of parameter and statistic and then can use them to find what does 58% denotes here.
The true statement is given by:
Option B: 58% is a statistic because it describes a sample characteristic.
What is a population and parameter?The entire group or system which we are taking in consideration is population. Nothing bigger than it lies there in consideration.
Ex: If we're taking about health problem in a country, then the whole country people form a population.
If we're taking about numbers on a 6 face die, then those 6 numbers on 6 faces form a population.
Those numbers who summarize information about population are called parameter.
What is sample and statistic?A portion of population taken and analyzed to predict information about population is called sample of that population.
Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.
Those numbers who summarize information about sample are called statistic.
(Statistic is different than statistics)
Using above definitions to conclude what 58% refers toSince the 58% is from the 4000 people randomly selected by the political scientist, thus, it is information about sample and thus, is a statistic.
Thus,
The true statement is given by:
Option B: 58% is a statistic because it describes a sample characteristic.

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Write an expression that represents the rabbit population in the year 2025, and solve it.
Answers
Answer:
Step-by-step explanation:
Your answer
Ok, lets do it systematically.
2005– 100 rabbits
3.4 % per year increasement.
So every year it increase 0.034 *100 = 3.4 per year
Total 2025-2005= 20 years
So expression is : 0.034*100*year(20)
Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]D = 25 + 0.3X[/tex]
The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:
[tex]D = b + mx[/tex]
Where
[tex]b = D\ intercept[/tex]
[tex]m = slope[/tex]
By comparing: [tex]D = 25 + 0.3X[/tex] to [tex]D = b + mx[/tex]
[tex]b = 25[/tex] and [tex]m = 0.3[/tex]
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in [tex]D = 25 + 0.3X[/tex]
[tex]D = 25 + 0.3 * 5[/tex]
[tex]D = 25 + 1.5[/tex]
[tex]D = 26.5[/tex]
The cost of 5 miles is $26
