Your class is in groups, working on an induction worksheet. One of the questions asks to prove that if n is even, then 8n is also even. Your group proves it, but you're then asked if the converse is also true. Your classmate suggests that it is. What would you say to explain how this suggestion is flawed, and how would you help correct them

Answers

Answer 1

Answer:

The answer is "this statement is not true".

Step-by-step explanation:

It is true because it can be achieved by using the initiation method. (Or at even a look, as n is still n=2m for the whole m, and the same number is 8n=8* (2*m)=2*(8*m). So it's confirmed !! )

Now the opposite declaration says, "If 8n would be an even amount then n is an even number", that's why the statement is not true.

An easy way of demonstrating why an argument also isn't valid is to show an example it against. Take into consideration the 24. 24=8*3. i.e. the shape is 8n, where it is n=3. Of course, 24 is also an equivalent number, but n=3 is an odd number here. So, we at least this one event, wherein the opposite statement could be sustained. (q.e.d).  

Note:- "8n would be an even number per each integer n." is true since 8n=2*(4n), even for all integer n.

A, B & C form the vertices of a triangle.

CAB = 90°, ABC = 60° and AB = 8.6.

Calculate the length of BC rounded to 3 SF.

BC =

Answers

Answer:

BC = 17.2.

Step-by-step explanation:

Since CAB = 90º, this is a right triangle.

The triangle format is given below:

C

A           B

We have that AB = 8.6, and angle B measures 60º.

Length of BC:

BC is the hypotenyse.

Side AB is adjacent to angle B = 60º.

In a right triangle, angle [tex]\alpha[/tex], it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:

[tex]\cos{\alpha} = \frac{s}{h}[/tex]

In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So

[tex]\cos{\alpha} = \frac{s}{h}[/tex]

[tex]0.5 = \frac{8.6}{h}[/tex]

[tex]0.5h = 8.6[/tex]

[tex]h = \frac{8.6}{0.5}[/tex]

[tex]h = 17.2[/tex]

BC = 17.2.

whats the GCF for 1248

Answers

Answer:

None or 12 depending on what the question is. See explanation below.

Step-by-step explanation:

If the number is 1248:

A single number cannot have a GCF. The GCF has be for at least two numbers.

If the numbers are 12 and 48, then the GCF can be calculated.

Since 12 is a factor of 48, then the GCF of 12 and 48 is 12.

In general, to calculate the GCF do this:

To calculate it, find the prime factors of 12 and 48.

12 = 2^2 * 3

48 = 2^4 * 3

GCF is the product of common factors with lower exponent.

GCF = 2^2 * 3 = 12

Answers

Answer:

both x angles are equal to 40 degrees

Answer:

x would equal 40

Step-by-step explanation:

a line is 180, the angle inside the triangle is 100 and x is on both sides that means x would equal 40 because there is 2 x's and 100 is already a number and 180 is a line.

180 = x + x + 100

x + x + 100 - 100 = 180 - 100

x + x = 80

2x = 80

2 ÷ 2x = 80 ÷ 2

x = 40

want to study procrastination and social anxiety levels in undergraduate students at your university.You send a group email to all students to sign up to be contacted about participating in research.Only 2000 students signed up to be contacted about participating in the research. You choose asample of 100 students using a simple random sample from the students who signed up. You assigna number to every student in the research participant database from 1 to 2000 and use an SRSmethod to select 100 numbers.Is this sample biased

Answers

Answer:

Yes.  There is a bias in the selected sample.

Step-by-step explanation:

Population of interest = undergraduate students at the university

Respondents to email requests = 2,000 students

Sample size = 100 students

Sample is based on the 2,000 respondents.

Therefore, sample is biased.

b) A sampling method is said to be biased if it systematically favors a group.  By making some members of the student population systematically more likely to be selected in a sample than others, there is an occurrence of sampling bias.  Usually, findings from biased samples can only be generalized to populations that share characteristics with the sample and to the entire population of interest.

There are 23 animals in the barn. Some are chickens some are goats. There are 80 legs in all. How many of each animal is there?

Answers

There are 17 goats and 6 chickens

Explaining: (1)  C + G = 23

As for legs:

(2)  2C + 4G = 80 (each C has 2 legs and each G has 4 legs)

Solving equation (1):  C = 23 - G

Substituting in equation (2)

2(23 - G) + 4G = 80

2G = 34

G = 17

C = 6

There are 17 goats and 6 chickens pretty sure.

What is a fraction?

A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value).  When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction. A proper fraction is also called fraction which is less than 1. A mixed fraction contains a sum of whole number and a proper fraction.

So, WE need to find the difference between the 6 and [tex]2 \frac{1}{5}[/tex].​

First we need to convert the mixed fraction into simple fraction.

[tex]2 \frac{1}{5}[/tex] = 11/5

Therefore, the difference between them will be;

6 -  [tex]2 \frac{1}{5}[/tex]  = 6 - 11/5

= 6 - 2.2

= 3.8

Hence, the difference between the 6 and [tex]2 \frac{1}{5}[/tex] will be 3.8

Answers

Answer:

What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1

                            =0,02

Step-by-step explanation:

Sample Space for rolling a die, S(1,2,3,4,5,6]

Since all the outcomes are equally P( rolling any numebre)=1/6

G1=(2,3,4,5,6)

Hence P(G1) =P (R2)+P (R3)+P (R4)+P (R5)+P (R6)

Hence P(G1) =5/6

and R3= [3]

Hence G1  ∩ R3 =  [3]  =  R3

Hence P(G1  ∩ R3) =P( R3) =1/6

What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1

Kimmie sells custom T-shirts for $12 each at the flea market every Saturday She usually sells 36 T-shirts Kimmie surveys her customers about whether they would buy her T-shirts at a different price. She determines that for every $1 increase in price she would sell two fewer T-shirts and for even $1 decrease in price, she would sell two more T-shirts, Which quadratic function can Kimmie use to model price increments vs. total income so that she can find the price at which her income is maximized?​

Answers

Answer:

y =  -2*x² + 60*x

Step-by-step explanation:

The general form of a quadratic function is:

y = a*x² + b*x + c

We need to determine a  ;  b  ;  and c. For that we have three conditions therefore

Condition 1       at  x = 12 $ each T-shirts kimmie sells 36 units, then she gets

12* 36 = 432 $    or      y  =  432   and

432 = a(12)² + 12*b + c      or   432 = 144*a + 12*b + c

Second condition   selling at 13 $ each T-shirt  she sells 34 , then

13*34 = 442

442  = a(13)²  +  13*b  + c    or   442 = 169*a + 13*b + c

And the third condition

11*38  = 418

418 = a* ( 121)  + 11*b  + c         418  =  121*a  +  11*b  + c

We have a three equation system

432 =   144*a + 12*b + c         (1)

442  =   169*a + 13*b + c       (2)

418 =    121*a  +  11*b  + c       (3)

We need to solve it for a,  b  and  c

Subtracting (2) - (1)        10 = 25*a  +  b    and subtracting (2) - (3)

24 = 48*a  + 2*b

Then       b  =  10 -  25*a         and     24  =  48*a + 2*( 10 - 25*a )

24  =  48*a +  20  - 50*a

24 -  20  =   -2*a

4  =  - 2*a    

a  = - 2      and   b =  10 - 25*( -2)     b = 60

Finally  c   is:    432 =   144*a + 12*b + c  

432  =  144* ( -2) + 12*60  + c

432  = -  288  +  720  +  c

432  = 432  + c

c =  0

The quadratic function is:

y =  -2*x² + 60*x
