Step-by-step explanation:

hope it helps you

Answer:

D.  If it is a pentagon, then it has five sides. If the polygon has five sides, then it is a pentagon

Step-by-step explanation:

Given statements;

      A polygon is a pentagon if and only if it has five sides.

From the statement we see that a pentagon has 5 sides. A body of this structure with 5 sides can be classified as a polygon.

Therefore, this bi-conditional statement is premised on two "if"s,

    If it is a pentagon then we are dealing with a body with 5 sides.

   And if such body has five sides, it is a polygon called pentagon

The correct option is D

Choice A, B and C are logically flawed.

A.  If it is a pentagon, then it has five sides. If it is a polygon, then it is a pentagon.

The emboldened part we do not know.

B.  If it is a pentagon, then it is a polygon. If it is a polygon, then it is a pentagon

 The emboldened part is flawed.

C. If it is a pentagon, then it is a polygon. If it is a polygon, then it has five sides.

We do not know if all pentagons have 5 sides.

Jill counted 20 pigs and chickens in the farm. Jack counted a total of 54 legs for the animals. How many chickens were there in the farm?​

Answers

Answer:

Let the number of chickens in the farm = x

Let the number of pigs in the farm = y

Number of legs of chickens = 2*x (since chickens have 2 legs)

Number of legs of pigs = 4*y (since pigs have 4 legs)

We are given that there are a total of 20 animals (pigs + chickens)

so, number of chickens + number of pigs = 20

x + y = 20

We are given that there is a total of 54 legs in the farm

so, legs of chickens + legs of pigs = 54

2x + 4y = 54

Solving for number of chickens and pigs:

from the question, we have deduced that:

x + y = 20

2x + 4y = 54

taking the value of x from the first equation and using it in the second equation

x = 20 - y

2(20-y) + 4y = 54

40 - 2y + 4y = 54

40 + 2y = 54

2y = 14

y = 7

Using this value of y in the first equation:

x + y  = 20

x + (7) = 20

x = 13

Therefore, there are 13 chickens and 7 pigs in the farm

Complete Question

According to the Bureau of Labor Statistics, citizens remain unemployed for an average of 15.9 weeks before finding their next job (June, 2008). Suppose you want to show that Louisiana has been effective in getting their unemployed back to work sooner. You take a random sample of 50 citizens who were unemployed six months earlier and ask them to report the duration. You find that the average time spent unemployed was 13.4 weeks with a sample standard deviation of the time unemployed is 6.7 weeks.

1 Which of the following statements is the correct alternative hypothesis?

2 The test statistic for testing the hypothesis is

a. -2.64

b. -2.32

c. -2.11

d. -1.28

e. none of these are correct

Answer:

1  

 The  alternative hypothesis  [tex]H_a  :  \mu < 15.9[/tex]

2

The  test statistics [tex]z =  -2.64 [/tex]  

Step-by-step explanation:

From the question we are told that

     The population  mean value for time  citizens remain unemployed is  [tex]\mu  =  15.9 \  weeks[/tex]

     The  sample size is  n =  50

     The  sample standard deviation is  6.7 weeks.

      The  sample mean value for time  citizens remain unemployed is  [tex]\mu  =  15.9 \  weeks[/tex]

       

     The  null hypothesis is  [tex]H_o  :  \mu \ge 15.9[/tex]

      The  alternative hypothesis  [tex]H_a  :  \mu < 15.9[/tex]

Generally test statistics is mathematically represented as

       [tex]z =  \frac{ \= x  - \mu }{ \frac{s}{\sqrt{n} } }[/tex]  

=>    [tex] z =  \frac{13.4 - 15.9}{\frac{6.7}{\sqrt{50}}}[/tex]

=>     [tex]z =  -2.64 [/tex]

A study by Allstate Insurance Co. finds that 82% of teenagers have used cell phones while driving (The Wall Street Journal, May 5, 2010). In October 2010, Massachusetts enacted a law that forbids cell phone use by drivers under the age of 18. A policy analyst would like to determine whether the law has decreased the proportion of drivers under the age of 18 who use a cell phone.
a. Select the null and the alternative hypotheses to test the policy analyst's objective.
A. He : p 0.82; Ha: p +8.82
B. He: P 8.82; HA: P8.82
b-1. Suppose a sample of 200 drivers under the age of 18 results in 150 who still use a cell phone while driving. What is the value of the test statistic? (Negative values should be Indicated by a minus sign. Round Intermedlete calculatlons to at least 4 decimal places and final answer to 2 declmal places.)
b-2. Find the p-value.
a. p-value<0.01
b. 0.01 s p-value<0.025
c. 0.025 s p-value d. 0.05 sp-value<0.10
e. p-value z 0.10
c-1. At a 0.05, do you reject the null hypothesis?
A. Yes, since the p-value is greater than significance level.
B. Yes, since the p-value is smaller than significance level.
C. No, since the p-value is greater than significance level.
D. No, since the p-value is smaller than significance level.
c-2. What is the conclusion?
A. The law has been effective since the pvalue is less than the significance level.
B. The law has not been effective since the pvalue is less than the significance level.
C. The law has been effective since the p-value is greater than the significance level.
D. The law has not been effective since the p-value is greater than the significance level.

Answers

Answer:

a)Null hypothesis; H0: p = 0.82

Alternative hypothesis; Ha: p < 0.82

b-1) test statistic = -2.57

b-2)The p-value = 0.00545

c-1)Option B: Yes, we will reject the null hypothesis since the p-value is smaller than significance level.

c-2) Option A: The law has been effective since the p-value is less than the significance level

Step-by-step explanation:

A) We are given population mean as 82% = 0.8.l2

Thus defining the hypothesis, we have;

Null hypothesis; H0: p = 0.82

Alternative hypothesis; Ha: p < 0.82

b-1) We are told that a sample of 200 drivers under the age of 18 results in 150 who still use a cell phone while driving. Thus; p^ = 150/200 = 0.75

Test statistic is given by the formula;

t = (p^ - p)/(√(p(1 - p)/n)

t = (0.75 - 0.82)/√(0.82(1 - 0.82)/200)

t = -0.07/0.0272

t = -2.57

b-2) From online p-value from t-value attached using; t = -2.57, significance level = 0.05, one tail distribution, and DF = 200 - 1 = 199, we have;

The p-value = 0.00545

c-1) Option B: Yes, we will reject the null hypothesis since the p-value is smaller than significance level.

C-2) We will conclude that;

The law has been effective since the pvalue is less than the significance level.

You can perform the t test for single mean to test the hypothesis.

The solutions are:

A: The null hypothesis: [tex]H_0: p= 0.82\\[/tex]

The alternate hypothesis: [tex]H_1: p < 0.82[/tex]

B: 1)  The value of t statistic is -2.58

2) The p value is 0.0053

C: 1)  Yes, since the p-value is smaller than significance level.

2)  The law has been effective since the p-value is less than the significance level.

How to form the hypothesis?

We take null hypothesis for events as if nothing changed. So we will  the changed population mean to be same as before. Or  [tex]H_0: p = 0.82\\[/tex]

And thus, the alternate hypothesis will be that the mean is decreased than 82% due to the new law, thus,

The alternate hypothesis: [tex]H_1: p < 0.82[/tex]

Solving for all problems:

A) We take null hypothesis for events as if nothing changed. So we will  the changed population mean to be same as before. Or  [tex]H_0: p = 0.82\\[/tex]

And thus, the alternate hypothesis will be that the mean is decreased than 82% due to the new law, thus,

The alternate hypothesis: [tex]H_1: p < 0.82[/tex]

B) 1) The sample size = n = 200, the percentage of people using phone is: [tex]\dfrac{150 \tiems 100}{200} = 75\%[/tex] thus p' = 0.75

The value of t statistic is calculated as:

[tex]t = \dfrac{p' - p}{\sqrt{(p)(1-p)/n}}\\\\t = \dfrac{0.75 - 0.82}{\sqrt{0.82 \times 0.18 / 200}} = -2.577[/tex]

2) p value from t table at df = 200 -1  == 199, we have p value at t = -2.58

The p value is 0.0053

C) 1) since the obtained p value is less than the significance level 0.05, thus we  will reject the null hypothesis and accept the alternate hypothesis. Thus,

Yes, since the p-value is smaller than significance level.

2) Thus, the conclusion is:

The law has been effective since the p-value is less than the significance level.

The solutions are:

A: The null hypothesis: [tex]H_0: p= 0.82\\[/tex]

The alternate hypothesis: [tex]H_1: p < 0.82[/tex]

B: 1)  The value of t statistic is -2.58

2) The p value is 0.0053

C: 1)  Yes, since the p-value is smaller than significance level.

2)  The law has been effective since the p-value is less than the significance level.

The median starting salary for new law school graduates is determined by

log(salary) = B0 + B1 LSAT + B2 GPA + B3 log(libvol) + b4 log(cost) + B5 rank + u,

where LSAT is the median LSAT score for the graduating class, GPA is the median college. GPA for the class, libvol is the number of volumes in the law school library, cost is the annual cost of attending law school, and rank is a law school ranking (with rank = 1 being the best).

i. Explain why we expect b5 < 0.
ii. What signs do you expect for the other slope parameters? Justify your answers.
iii. Using the data in LAWSCH85.RAW, the estimated equation is log(salary ) = 8.34 + .0047 * LSAT + .248 GPA + .095 log(libvol) + .038 log(cost) - .0033 rank n = 136, R^2 = .842

What is the predicted ceteris paribus difference in salary for schools with a median GPA different by one point? (Report your answer as a percentage.)

iv. Interpret the coefficient on the variable log(libvol).
v. Would you say it is better to attend a higher ranked law school? How much is a difference in ranking of 20 worth in terms of predicted starting salary?.

Answers

Step-by-step explanation:

1) we would have the expectation that b₅ < 0 because b₅ shows how salary responds to law school ranking. As the rank of law school increases then median starting salary for new law school graduates declines. there is an inverse relation between salary and rank, Coefficient of rank, b5 will be negative since it is less than 0

ii) B₁ is going to be positive because as median LSAT score for the graduating class goes up, so does the salary of graduates. we have B1 >0

B₂ will be positive as college median GPA rises, so does graduate salary.

B₃ will be positive because if the more volumes of book in library, the greater possibility of getting higher salary, so B₃ >0.

B₄ >0 as if annual cost is high , then there would be indictaes more facilities of learning for students, leading to more chances of high salaries , hence B4 >0.

B5<0 this has been explained in 1.

iii) predicted ceteris paribus difference in salary for schools with a median GPA different by one point

= coefficient of GPA

=0.248

= this 24.8% in percentages B₂ tells us that when other factors are held constant,increasing median gpa by 1 would cause 24.8 percent increase in salary predicted.

iv)holding other variable factors constant, increasing the volume in the law library would bring about predicted salary increase by 0.095%

v) due to the inverse relationship between rank of law school and salary, it is better to attend a law school with lower rank than that with higher rank

difference in ranking of 20 = 20*(-0.0033)

= -0.066  x 100

= -6.6%

if rank is lower by 20 units , then we will have salary to be 6.6% higher

Answer:

x=10

Step-by-step explanation:

First, you gotta get the numbers with the x on one side and the whole numbers on the other side.

So, since there is a -3 on the right side, make that 0 by adding 3. Whatever you do to one side you have to do to the other side, so then add 3 the the left side. You should have 12x=9x+30.

Now, get the Xs on one side. Since there is a positive 9x on the left side, subtract 9x from that side to make that 0. Again, whatever you do to one side you have to do to the other side, so subtract 9x from the right side as well. This should leave you with 3x=30.

In order to get x by itself, we need to divide because when 2 things (in this case the 3 and the x) are right next to each other (no space in between,) it means they are multiplied together. To get x by itself, we need to do the opposite which is divide. 3x/3=x      30/3=10         So, x=10

btw, /=divide

Answer:

12x – 3 = 9x +27

=> 12x – 9x = 27 + 3

=> 3x = 30

=> x = 30/ 3

=> x = 10

The table which represents a linear function is table 4.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The tables in the question

Now,

The table that represents a linear function is:

X   Y

1   3

2   7

3   11

4   15

The reason this is a linear function is that for each increase in the input value of X by 1, the output value of Y increases by a constant amount of 4. In other words, the rate of change of Y with respect to X is constant at 4, indicating a linear relationship between the two variables.

Therefore, the answer of the function will be table 4.
