joseph wants to find the side length of a square that has an area of 150 feet. Should his answer be rational or irrational ? why ?

Answer:

d) $146.15

Step-by-step explanation:

From the above Question, we are given the following values:

The annual dividend per share of a perpetual preferred stock = $9.50

The required return rate on this preferred stock = 6.5% = 0.06

The selling price of the stock = ??

The formula to calculate the Selling price of the stock =

Annual dividend per share / Required return rate

= $9.5/ 0.065

= $146.15384615

Approximately $146.15

Therefore, the price at which the stock should sell is $146.15.

Answer:  $0.27

Step-by-step explanation:

7a + 11b = 1.47

        7a = 1.47 - 11b

          [tex]a=\dfrac{1.47-11b}{7}[/tex]

Make a table. Choose values for b starting at $0.01 and solve for "a".

The value of "a" must terminate at the hundredths place since we are working with money.

You will discover that a = 0.10 and b = 0.07

The cost of 2 apples and 1 banana is:

  2a + b

= 2(0.10) + (0.07)

=    0.20 + 0.07

=          0.27

Answer:

(-4,-1)

Step-by-step explanation:

If a line must be parallel, then its slope must be the same.

Their points can be different, the slope should be same.

So, y = 1/3x - 4

=> We find the slope of the equation:

=> Slope = the number with which "x" is multiplied

=> Slope of this equation = 1/3

So, we need to find the point that makes a slope of 1/3 from (-3, 2)

=> Slope = y/x - y1/x1

=> 1/3 = -3/2 - y1/x1

=> y1/x1 = -3/2 - 1/3

=> y1/x1 = -3-1 / 2-3

=> y1/x1 = -4/-1

So, the point is (-4,-1)

Answer:

C.

Step-by-step explanation:

Since the radius of the circle is 12 units, we can calculate the circumference.

2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.

The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.

[tex]\frac{24\pi }{360} =\frac{x}{240}[/tex]

[tex]\frac{24\pi }{6} =\frac{x}{4}[/tex]

[tex]\frac{4\pi }{1} =\frac{x}{4}[/tex]

1 * x = 4 * 4 * pi

x = 16pi

So, your answer is C.

Answer:

Question 1

a) Range

= $2962

b) Variance

= $680557.4954

c) Standard Deviation

= $824.9590871

Question 2

Are there any​ outliers, and are they likely to have much of an effect on the measures of​ variation?

Yes, there are outliers present I the given sample data.

These outliers are the larger cost for marriage proposals which are: 1750, 3000

These largest costs are much bigger than the rest of the​ sample data, and they would likely have much of an effect on the measures of​ variation

Step-by-step explanation:

We are given the following sample data in dollars

38, 50, 50, 55, 55, 95, 95, 130, 180, 213, 250, 350, 450, 1750, 3000

Question 1

a) Range

This is the difference between the maximum cost and the minimum cost

The minimum cost = $38

The maximum cost = $3000

Range = $3000 - $38

= $2962

b) Variance

Reading the question, we are given sample data.

Hence, we use the formula for Variance of a sample

= (Mean - x)²/N - 1

Step 1

We find the Mean

Mean = Sum of terms/Number of terms

Number of terms = 15

Mean = 38 + 50 + 50 + 55 + 55 + 95 + 95 + 130 + 180 + 213 + 250 + 350 + 450+ 1750 + 3000/15

= $6761/15

= $450.7333333

Step 2

(x - Mean)²/N - 1

N = 15

= $[(38 - 450.7333333)²+ (50 + 450.7333333)²+( 50 +450.7333333)² + (55 +450.7333333)² + (55 +450.7333333)² + (95 + 450.7333333)²+ (95 +450.7333333)²+ (130 +450.7333333)²+ (180 +450.7333333)² + (213 + 450.7333333)²+ (250 +450.7333333)² + (350 + 450.7333333)² + (450 +450.7333333)²+ (1750 +450.7333333)² + (3000 +450.7333333)²]/15 - 1

=$ (- 412.7333333² + -400.7333333² + -400.7333333² + -395.7333333² + -395.7333333² + -355.7333333² + -355.7333333² + -320.7333333² + -270.7333333² + -237.7333333² + -200.7333333² + -100.7333333² + -0.7333333333² + 1299.266667² + 2549.266667²)/15 - 1

= $( 170348.8044+ 160587.2044, 160587.2044+ 156604.8711, 156604.8711+ 126546.2044, 126546.2044+ 102869.8711, 73296.53776+ 56517.13776, 40293.8711+ 10147.20444+ 0.5377777777+ 1688093.872, 6498760.539)/14

= $9527804.935/14

Variance = $680557.4954

c) Standard deviation = √Variance

Standard deviation = √$680557.4954

= $824.9590871

Question 2

Are there any​ outliers, and are they likely to have much of an effect on the measures of​ variation?

Yes, there are outliers present in the given sample data.

Answer:

The height and  width of the interior tile =  3·x + 4 - 4 = 3·x and 2·x + 4  - 4= 2·x

Please see attached diagram

Step-by-step explanation:

The given parameters are;

The given rectangular floor tile  with width = 3·x + 4 and height = 2·x + 4

Where, x is in centimetres

The interior tile maintains a height to width ration of 2:3

The dimension of the trim border = 2 cm

Therefore;

The relationship between the width and height of the interior and exterior tiles is given as follows

Width of exterior tile = Width of interior tile + 2 × The dimension of the trim border

Which gives;

Width of exterior tile = Width of interior tile + 2 × 2 = Width of interior tile + 4

Height of exterior tile = Height of interior tile + 2 × The dimension of the trim border

Height of exterior tile = Height of interior tile + 2 × 2 = Height of interior tile + 4

Where the interior tile maintains a height to width ration of 2:3, we have;

For a unit length x, The height and the width of the interior tiles are 2·x:3·x

Therefore, for a given height 2·x, the width will be 3·x

Given the width of the exterior tile =  3·x + 4

The height of the exterior tile will then be 2·x + 4 and the width of the exterior tile will be 3·x + 4

The sides ratio of the interior tiles remain 2·x:3·x = 2/3

Answer:

13.9 miles

Step-by-step explanation:

If we draw out the way he drove, the drive from his home to the intersection represents the long leg of a right triangle and the short leg can be represented by his drive from the intersection to the workplace.

A road from his home to work would represent the hypotenuse.

Since we know the distances of the legs, we can use the pythagorean theorem to find the hypotenuse, or the distance of the new road.

Plug in the values:

a² + b² = c²

12² + 7² = c²

193 = c²

13.9 = c

= 13.9 miles

The measure of the angle y is 120°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

The Sum of the three angles is 180 degrees.

33 + 87 + x = 180

x = 180 - 120

x = 60

Now,

x + y = 180

60 + y = 180

y = 180 - 60

y = 120

Thus,

The value of y is 120°.

Answer:

The area of the triangle is 24 [tex]\text{cm}^{2}[/tex].

Step-by-step explanation:

We are given that the length of the base of a right-angle triangle ABC is 6 cm and the length of the hypotenuse is 10 cm.

And we have to find the area of the triangle.

As we know that the area of the triangle is given by the following formula;

Area of the triangle =  [tex]\frac{1}{2}\times \text{Base} \times \text{Height}[/tex]

Firstly, we will find the height (perpendicular) of the triangle ABC bu using the Pythagoras Theorem.

[tex]\text{Hypotenuse}^{2} =\text{Perpendicular}^{2} +\text{Base}^{2}[/tex]

[tex]\text{10}^{2} =\text{Perpendicular}^{2} +\text{6}^{2}[/tex]

[tex]100=\text{Perpendicular}^{2} +36[/tex]

[tex]\text{Perpendicular}^{2} =100-36[/tex]

[tex]\text{Perpendicular}^{2} =64[/tex]

[tex]\text{Perpendicular} =\sqrt{64}[/tex]  = 8 cm.

Now, the area of the triangle =  [tex]\frac{1}{2}\times \text{Base} \times \text{Height}[/tex]

                                                =  [tex]\frac{1}{2}\times \text{6} \times \text{8}[/tex]

                                                =  24 [tex]\text{cm}^{2}[/tex]

Hence, the area of the triangle is 24 [tex]\text{cm}^{2}[/tex].

Answer:

From the given information:

the null hypothesis and the alternative hypothesis can be computed as follows:

[tex]\mathbf{H_o:}[/tex] The sample have a distribution that agrees with the distribution of state populations.

[tex]\mathbf{H_1:}[/tex] The sample have a distribution that does not agrees with the distribution of state populations.

The Chi-Square test statistics [tex]\mathbf{X^2 = \dfrac{(Observed \ value - Expected \ value )}{(Expected \ value ) ^2 }}[/tex]

Among the four northwestern states, Washington has 51% of the total population, Oregon has 30%, Idaho has 11%, and Montana has 8%. A market researcher selects a sample of 1000 subjects, with 450 in Washington, 340 in Oregon, 150 in Idaho, and 60 in Montana.

The observed and the expected value can be computed as follows:

States           Observed           Expected                        [tex]X^2 = \dfrac{(O- E)^2}{E}[/tex]

Washington     450             0.51 × 1000 = 510

Oregon            340              0.30 × 1000 = 300

Idaho                150               0.11  × 1000 = 110

Montana             60              0.08 × 1000 = 80

Total                 1000                                1000

For washington :

[tex]X^2 = \dfrac{(O- E)^2}{E}[/tex]

Answer:

[tex]P(X\leq 1) = 0.331[/tex]

Step-by-step explanation:

Given

Poisson Distribution;

Average rent in a week = 2.3

Required

Determine the probability of renting no more than 1 apartment

A Poisson distribution is given as;

[tex]P(X = x) = \frac{y^xe^{-y}}{x!}[/tex]

Where y represents λ (average)

y = 2.3

Probability of renting no more than 1 apartment = Probability of renting no apartment + Probability of renting 1 apartment

Using probability notations;

[tex]P(X\leq 1) = P(X=0) + P(X =1)[/tex]

Solving for P(X = 0) [substitute 0 for x and 2.3 for y]

[tex]P(X = 0) = \frac{2.3^0 * e^{-2.3}}{0!}[/tex]

[tex]P(X = 0) = \frac{1 * e^{-2.3}}{1}[/tex]

[tex]P(X = 0) = e^{-2.3}[/tex]

[tex]P(X = 0) = 0.10025884372[/tex]

Solving for P(X = 1) [substitute 1 for x and 2.3 for y]

[tex]P(X = 1) = \frac{2.3^1 * e^{-2.3}}{1!}[/tex]

[tex]P(X = 1) = \frac{2.3 * e^{-2.3}}{1}[/tex]

[tex]P(X = 1) =2.3 * e^{-2.3}[/tex]

[tex]P(X = 1) = 2.3 * 0.10025884372[/tex]

[tex]P(X = 1) = 0.23059534055[/tex]

[tex]P(X\leq 1) = P(X=0) + P(X =1)[/tex]

[tex]P(X\leq 1) = 0.10025884372 + 0.23059534055[/tex]

[tex]P(X\leq 1) = 0.33085418427[/tex]

[tex]P(X\leq 1) = 0.331[/tex]

Answer:

4 ounces

Step-by-step explanation:

If you divide the 164 ounces by the 8 ounces per glass, you get 20.5 glasses filled. So, half of the last glass would be 4.

Answer:

4 ounces

Step-by-step explanation:

We're looking for the remainder of ounces.

To find how many FULL glasses will be made, we divide 8 by 164 and look at the integer part of the number.

[tex]164\div8=20.5[/tex]

So 2 full glasses were made.

To find the remainder, we multiply 20 by 8 and subtract from 164.

Answer:

a.) mean = 9.23

ii) The mean represents the centre (A)

b) Median = 9

ii) The median represents the centre (A)

c) Mode = 8

ii)  The​ mode(s) does​ (do) not represent the center because it​(one) is the smallest data value. (D)

Step-by-step explanation:

Arranging the data in ascending order:

8 8 8 8 8 8 9 9 9 10 11 12 12

a) calculating for mean

[tex]\bar x = \frac{sum\ of\ data}{number\ of\ data}\\ \bar x = \frac{8+8+8+8+8+8+9+9+9+10+11+12+12}{13} \\\bar x =\frac{120}{13} \\\bar x = 9.23[/tex]

ii) does the mean represent the centre of the data?

The measure of central tendency/location is a statistical tool used to accurately depict values that are at the central location of the data set

Yes, the mean represents the centre of the data, because there are no outliers in the data set. Outliers are unusual values compared to the rest of the values in the dataset.

b) calculating the median (M)

[tex]M =( \frac{n\ +\ 1}{2})th\ term\\ \\where:\\n = number\ of\ data\ in\ the\ dataset = 13\\\\\therefore M = \frac{13+1}{2}\\ M = \frac{14}{2} \\M= 7th\ term[/tex]

The 7th term after arranging in ascending or descening order, is the median term

8 8 8 8 8 8 9 9 9 10 11 12 12

∴ Median = 9

ii) Yes, the Median represents the center of the data, because it litterally tells the data at the middle of the distribution  

c) The mode is the data with the highest number of occurrence in the dataset (highest frequency);  8 8 8 8 8 8 9 9 9 10 11 12 12

The data with the highest number of occurrence is 8, which occurred 6 times.

Mode = 8

ii) The mode does not represent the centre of the data because it is the smallest value in the dataset, hence it doesn't tell the value that is the middle term.

However, if you just add zeros, they essentially just become placeholders. 3 already has 0 for decimals, so it is equal to 3.0 and 3.00.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{a = 8}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{4a + 10 = 2a + 26}[/tex]

Move 2a to left hand side and change it's sign

Similarly, move 10 to right hand side and change it's sign

⇒[tex] \sf{4a - 2a =26 - 10}[/tex]

Collect like terms

⇒[tex] \sf{2a = 26 - 10}[/tex]

Subtract 10 from 26

⇒[tex] \sf{2a = 16}[/tex]

Divide both sides of the equation by 2

⇒[tex] \sf{ \frac{2a}{2} = \frac{16}{2} }[/tex]

Calculate

⇒[tex] \sf{a = 8}[/tex]

Answer:

0

Step-by-step explanation:

We need to solve the given expression for the value of h.

- 4(-5h-4)=2(10h+8)

Opening brackets on both sides of the above equation

+20h+4=20h+16

Taking h terms on the one side and the constants on the another side

20h-20h=16-4

0=20

It means that the value of - 4(-5h-4)=2(10h+8) is equal to 0.
