Answer:

C). Zero

Step-by-step explanation:

This is a pretty simple question.

Any number multiplied by zero will be zero, and zero cannot have a positive or negative sign, which is why zero has its own sign, which is known as the Sign of Zero.

Answer:

The values of the box-plot are: B = {8.2, 8.3, 8.4, 8.5 and 8.9}.

Step-by-step explanation:

The data provided is as follows:

X     Frequency

8        0

8.1        0

8.2        2

8.3        2

8.4        2

8.5        3

8.6        0

8.7         1

8.8        0

8.9         1

 9           0

So, the actual data is:

S = {8.2 , 8.2 , 8.3 , 8.3 , 8.4 , 8.4 , 8.5 , 8.5 , 8.5 , 8.7 , 8.9 }

A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,

The data set is arranged in ascending order.

The minimum value is, Min. = 8.2

The lower quartile is,

[tex][\frac{n+1}{4}]^{th}\ obs.=[\frac{11+1}{4}]^{th}\ obs.=3^{rd }\ obs. =8.3[/tex],

Q₁ = 8.3.

The median value is,

[tex][\frac{n+1}{2}]^{th}\ obs.=[\frac{11+1}{2}]^{th}\ obs.=6^{th}\ obs.=8.4[/tex]

Median = 8.4

The upper quartile is,

[tex][\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(11+1)}{4}]^{th}\ obs.=9^{th }\ obs. =8.5[/tex],

Q₃ = 8.5.

The maximum value is, Max. = 8.9.

So, the values of the box-plot are: B = {8.2, 8.3, 8.4, 8.5 and 8.9}.

Answer:

The values of the box-plot are: B = {8.2, 8.3, 8.4, 8.5 and 8.9}.

Good luck on your assignment..

First divide 36 by 9 and get 4, now you have your number of minutes per song. Now multiply that by 20 to get 80 minutes for 20 songs.

In short: 80 minutes for 20 songs.

Step-by-step explanation:

first find the side length by

considering a triangle under

the square

[tex]l \: = \sqrt{ {3}^{2} + {1}^{2} } = \sqrt{10} \: cm \\ area \: = \: \sqrt{10} \times \sqrt{10} = 10 \: {cm}^{2} \: \: \: \: ans[/tex]

Answer:

Smallest angle - ∠M

Largest angle - ∠N

Step-by-step explanation:

In a triangle opposite side of a largest angle is largest and opposite side of a the smallest angle is smallest.

In the given triangle LMN,

Side lengths of the triangle have been given as,

LM = 27 in.

MN = 25 in.

LN = 24 in.

Relationship in these sides will be,

LM > MN > LN

Therefore, relationship in their opposite sides will be,

∠N > ∠L > ∠M

The smallest angle of the triangle is angle M.

And the largest angle of the triangle is angle N.

Results:

x = 3 - i sqrt(90015)

x = 3 + i sqrt(90015)

Answer:

Step-by-step explanation:

x^4 – 16x^3 + 96x^2 – 256x + 256

terms with odd exponents are negative

x^4 has a coefficient of one, so the expression's GCF is 1

Thus, we need to factor out the expression as it is:

(x-4)*(x-4)*(x-4)*(x-4)

Lets multiply it out to check:

(x-4)*(x-4)*(x-4)*(x-4)=

(x^2-8x+16)*(x^2-8x+16)=

x^4−8x^3+16x^2−8x^3+64x^2−128x+16x^2−128x+256=

x^4 – 16x^3 + 96x^2 – 256x + 256

thus, the factored form is:

(x-4)*(x-4)*(x-4)*(x-4) or (x-4)^4

Answer:

(B) The electrician charges $40 per hour.

Step-by-step explanation:

Total cost=fixed cost + variable cost

F(x)=60+40x

Fixed cost =60

Variable cost=40x

x=hours of service

40=40 dollar per hour charge

The coefficient 40 represent the electrician charge of $40 per hour

(B) The electrician charges $40 per hour.

Answer:

0 solution

Step-by-step explanation:

Given

[tex]x^2 + 5x+ 7 = 0[/tex]

Required

Find number of solutions;

The number of solutions can be determined via the value of determinants, D;

Such that

[tex]D = {b^2} - {4ac}[/tex]

By comparing the general form of equation;

[tex]ax^2 +bc x + c = 0[/tex]

with [tex]x^2 + 5x+ 7 = 0[/tex]

This gives

[tex]a = 1\\b = 5\\c = 7[/tex]

So;

[tex]D = {b^2} - {4ac}[/tex] becomes

[tex]D = {5^2} - {4*1*7}[/tex]

[tex]D = {25} - {28}[/tex]

[tex]D = -3[/tex]

The calculated value of D is less than 0;

This implies that [tex]x^2 + 5x+ 7 = 0[/tex] has no real solution

Answer:

Perimeter of the rectangle is 16x+18 units.

Step-by-step explanation:

The area of rectangle is

[tex]7x^2+57x+8[/tex]

First we have to find the factor form of above expression.

Splitting the middle term, we get

[tex]7x^2+56x+x+8[/tex]

[tex]7x(x+8)+1(x+8)[/tex]

[tex](x+8)(7x+1)[/tex]

Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).

Perimeter of a rectangle is

[tex]Perimeter=2(l+b)[/tex]

[tex]Perimeter=2[(x+8)+(7x+1)][/tex]

[tex]Perimeter=2[8x+9][/tex]

[tex]Perimeter=16x+18[/tex]

Therefore, the perimeter of the rectangle is 16x+18 units.

Answer:

[tex]\overline {PM} \cong \overline {ON}[/tex] because they are opposite sides of a parallelogram.

Step-by-step explanation:

First of all, let us have a look at the definition of a parallelogram.

A parallelogram is a closed 4 sided figure (i.e. a quadrilateral) made up with two pairs of straight lines such that the two pairs are parallel and equal to each other.

For example, let us consider a quadrilateral ABCD as attached in the diagram in answer area.

The two pair of lines are:

AB,  DC and BC, AD

For ABCD to be a parallelogram, the lines

AB and DC must be parallel to each other and AB = DC

AND

BC and AD must be parallel to each other and BC = DA

------------------------------

In the given question, we are given that the quadrilateral MNOP is a parallelogram.

The two pairs opposite lines are OP, NM and PM, ON.

As per the definition of a parallelogram,

OP and NM must be parallel and equal to each other.

AND

PM and ON must be parallel and equal to each other.

[tex]\therefore[/tex] [tex]\overline {PM} \cong \overline {ON}[/tex].

Hence proved.

Step-by-step explanation:

Because a parallelogram would be the result.

Answer:

Base = 6ft

Height =9ft

Step-by-step explanation:

Area of a triangle: 1/2 x base length x height

Base = b

Height = b+3

27 = 1/2 x b x (b+3)

27/(1/2) = b (b+3)

54= b^2 +3b

0=b^2 +3b -54

For: ax2+ bx + c  

a=1 ; b=3 ; c =-54

x =[ -b ± √b²-4ac] /2a  

Replacing with the values given:  

x =[ -3 ± √(3)²-4(1)-54] /2(1)  

x = [ -3± √9 +216] /2  

x = [-3 ± √225] /2  

x = [ -3 ± 15] /2  

Positive:  

x = [ -3 + 15] /2 =12/2 = 6  

b= 6 ft (base length)

Height =b+3 = 6+3 = 9 ft

Feel free to ask for more if needed or if you did not understand something.  

Answer:

m∠B ≈ 41.81°

Step-by-step explanation:

If we draw a picture, it would help a lot. Once we visualize the triangle, we can see that we have sin∅ = 2/3. So, plugging into your calc,

sin∅ = 2/3

∅ = sin^-1(2/3)

∅ = 41.8103

m = least prime number = 2

n = least positive integer multiple of 12 = 12

n - m = 12 - 2 = 10

Answer:

10

Step-by-step explanation:

2 is the least prime number because it is not a product of any two smaller natural numbers. m=2

12 is the least positive integer multiple of 12. n=12

Answer:

(2,5)

Step-by-step explanation:

Answer:

(1) Correct option (A).

(2) The probability that Aadi will get Tails is 0.40.

Step-by-step explanation:

The information provided is:

The probability of tail in both cases is:

[tex]P(T|E)=\frac{3}{10}=0.30[/tex]

[tex]P(T|S)=\frac{20}{50}=0.40[/tex]

Here,

P (T|E) implies the probability of tail in case of Eric's experiment.

P (T|S) implies the probability of tail in case of Sue's experiment.

(1)

Now, it is given that Aadi is going to throw the coin once.

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

In this case we need to compute the probability of Aadi getting Tails in a single toss.

As Sue uses a larger number of trials in the experiment, i.e. n = 50 > 30 times, according to the Central limit theorem, Sue's estimate is best because she throws it .

Thus, the correct option is (A).

(2)

As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:

[tex]P(\text{Aadi will get Tails})=P(T|A)[/tex]

                                   [tex]=P(T|S)\\\\=0.40[/tex]

Thus, the probability that Aadi will get Tails is 0.40.

Answer:

The correct answer is C and 23/60

Step-by-step explanation:

Sue's estimate is best because she throws it more times than Eric.

This is because the more you throw a coin the more reliable the results will be compared to data from a coin that has been thrown less, therefore the answer is C.

For the second half you need to add the number of tails together to get you numerator and then add the amount of times the coin was thrown to get your denominator, (giving you 23/60)

Hope this helped :)
