Answer:

At most 25% of homes will have a monthly utility bill of less than $105.

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

In this question, we have that:

The mean is $123.

The standard deviation is $9.

What percentage of homes will have a monthly utility bill of less than $105

105 = 123 - 2*9

So 105 is two standard deviations below the mean.

We have that, by the Chebyshev Theorem, at least 75% of the measures will be within 2 standard deviations from the mean, so at most 25% of the measures will be more than two standard deviations of the mean(greater than 141 ou lesser than 105).

So at most 25% of homes will have a monthly utility bill of less than $105

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

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

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

Answer:

3.8

Step-by-step explanation:

6 - 2 1/5 = 6 - 11/5

= 6-2.2

=3.8

The difference between the 6 and 2 1/5 will be 3.8

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

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

P(G1  ∩ R3) / P(G1) = (1/6)/ (5/6=

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.

Step-by-step explanation:

✔️When input (n) = -1:

f(n) = 2n - 1

f(-1) = 2(-1) - 1

f(-1) = -2 - 1 = -3

✔️When input (n) = 7:

f(n) = 2n - 1

f(7) = 2(7) - 1

Step-by-step explanation:

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.
