Answer:

a) 0.00019923%

b) 47.28%

Step-by-step explanation:

a) To find the probability of all sockets in the sample being defective, we can do the following:

The first socket will be in a group where 5 of the 38 sockets are defective, so the probability is 5/38

The second socket will be in a group where 4 of the 37 sockets are defective, as the first one picked is already defective, so the probability is 4/37

Expanding this, we have that the probability of having all 5 sockets defective is: (5/38)*(4/37)*(3/36)*(2/35)*(1/34) = 0.0000019923 = 0.00019923%

b) Following the same logic of (a), the first socket have a chance of 33/38 of not being defective, as we will pick it from a group where 33 of the 38 sockets are not defective. The second socket will have a chance of 32/37, and so on.

The probability will be (33/38)*(32/37)*(31/36)*(30/35)*(29/34) = 0.4728 = 47.28%

Answer:

[tex]\text{Unemployment rate}\approx 7.7\%[/tex]

[tex]\text{Labor force participation rate}\approx 92.9\%[/tex]

Step-by-step explanation:

We have been given that the number of employed persons equals 180 million. The number of unemployed persons equals 15 million, and the number of persons over age 16 in the population equals 210 million. We are asked to find the unemployment rate and the labor force participation rate.

[tex]\text{Unemployment rate}=\frac{\text{Number of unemployed person}}{\text{Labor force}}\times 100\%[/tex]

We know that labor force is equal to employed population plus unemployed population.

[tex]\text{Unemployment rate}=\frac{\text{15 million}}{\text{180 million + 15 million}}\times 100\%[/tex]

[tex]\text{Unemployment rate}=\frac{\text{15 million}}{\text{195 million}}\times 100\%[/tex]

[tex]\text{Unemployment rate}=0.0769230769\times 100\%[/tex]

[tex]\text{Unemployment rate}=7.69230769\%[/tex]

[tex]\text{Unemployment rate}\approx 7.7\%[/tex]

Therefore, the unemployment rate is approximately 7.7%.

[tex]\text{Labor force participation rate}=\frac{\text{Labor force}}{\text{Total eligible population}}\times 100\%[/tex]

[tex]\text{Labor force participation rate}=\frac{\text{195 million}}{\text{210 million}}\times 100\%[/tex]

[tex]\text{Labor force participation rate}=\frac{195}{210}\times 100\%[/tex]

[tex]\text{Labor force participation rate}=0.9285714285714286\times 100\%[/tex]

[tex]\text{Labor force participation rate}=92.85714285714286\%[/tex]

[tex]\text{Labor force participation rate}\approx 92.9\%[/tex]

Therefore, the labor force participation rate is approximately 92.9%.

The unemployment rate is 7.69% and the labor force participation rate is 92.86%.

The unemployment rate can be calculated by dividing the number of unemployed persons by the labor force and multiplying by 100. In this case, the number of unemployed persons is 15 million and the labor force is the sum of employed and unemployed persons, which is 180 million + 15 million.

The labor force participation rate can be calculated by dividing the labor force by the total number of persons over age 16 and multiplying by 100. In this case, the total number of persons over age 16 is 210 million.

Unemployment rate: (15 million / (180 million + 15 million)) x 100 = 7.69%

Labor force participation rate: ((180 million + 15 million) / 210 million) x 100 = 92.86%

Answer:

P ( 2 R , 4 O , 6 G ) = 0.0261

Step-by-step explanation:

Given:

- Red beans = 8

- Orange beans = 6

- Green beans = 9

Find:

What is the probability of reaching into the bag and randomly withdrawing 12 jellybeans such that the number of red ones is 2, the number of orange ones is 4, and the number of green ones is 6?

Solution:

- The question requires the number of selection of 12 jellybeans we can make from total available such that out of those 12 we choose 2 Red, 4 Orange and 6 Green.

- For selection we will use the combinations. So to choose 2 Red from 8; Choose 4 Orange from 6 and 6 green from 9 available. The number of possible outcomes with such condition is:

          Outcomes ( 2 R , 4 O , 6 G ) = 8C2 * 6C4 * 9C6

                                                         = 28*15*84

                                                         = 35280

- The total number of outcomes if we randomly select 12 beans irrespective how many of each color we select from available 23 we have:

          Outcomes ( Select 12 from 23 ) = 23C12

                                                               = 1352078

- Hence, the probability for the case is given by:

P ( 2 R , 4 O , 6 G ) = Outcomes ( 2 R , 4 O , 6 G ) / Outcomes ( Select 12 from 23 )

P ( 2 R , 4 O , 6 G ) = 35280 / 1352078 = 0.0261

Answer:

Therefore the radius of curvature at A is 432.03 m.

Step-by-step explanation:

Radius of curvature : If an object moves in curvilinear motion, then any point of the motion, the radius of circular arc path which best approximates the curve at that point is called radius of curvature.

Radius of curvature =[tex]\rho = \frac{V^2_p}{a}[/tex]

[tex]V_p[/tex]= velocity

a = acceleration perpendicular to velocity.

Velocity at the point A = [tex]V_A= 100 \ km/h[/tex] [tex]=\frac{100 \ km}{1 \ h}= \frac{100\times 1000 \ m}{3600 \ s}=\frac{250}{9}[/tex] m/s

Velocity at the point C [tex]=V_C=50 \ km/ h=\frac{125}{9} \ m/s[/tex]

The distance between A and B is 120 m.

To find the declaration between the point A and C we use the following formula

[tex]V^2_C=V^2_A+2a_ts[/tex]

[tex]\Rightarrow( \frac{125}{9})^2=(\frac{250}9})^2+2a_t.120[/tex]

⇒[tex]a_t[/tex] = -2.41 m/s²

[tex]a_t[/tex]= tangential acceleration

Given the passengers experience a total acceleration of 3 m/s².

Total acceleration= 3 m/s².

[tex]a = \sqrt{a^2_t+a^2_n[/tex]

[tex]\Rightarrow a^2_n= a^2- a^2_t[/tex]

[tex]\Rightarrow a_n=\sqrt{3^2-(-2.41)^2}[/tex]

       = 1.786 m/s²

Radius of curvature  [tex]\rho_A=\frac{V^2_A}{a_n}[/tex]

                                   [tex]=\frac{(\frac{250}{9})^2}{1.786}[/tex]

                                  = 432.03 m

Therefore the radius of curvature at A is 432.03 m.

The probability of picking a red marble 3 times in a row  = [tex](\frac{8}{125})[/tex]

Step-by-step explanation:

Here, the total number of red marbles  =  4

The total number of blue marbles  = 6

Now, as the Repetition is allowed.

Let E: The event of picking a red marble

[tex]P(E) = \frac{\textrm{The total number of red marbles}}{\textrm{Total marbles}}[/tex]

So, [tex]P(E) = \frac{4}{10} = \frac{2}{5}[/tex]

Now, as we know after first picking, the chosen red marble is REPLACED in the bowl.

So, again the bowl has 4 red marbles and 10 in total.

⇒P(picking a red marble again)  = 2/5

And similarly for the third time.

So, the probability of picking a red marble 3 times in a row  = [tex](\frac{2}{5}) \times (\frac{2}{5})\times (\frac{2}{5}) = \frac{8}{125}[/tex]

The probability of selecting a red marble on each of the three picks is 2/55.

To determine the probability of selecting a red marble on each of the three picks, we need to consider the number of red and blue marbles in the bowl and the fact that a marble is replaced after each pick.

First, there are 4 red marbles and 6 blue marbles in the bowl. For the first pick, the probability of selecting a red marble is 4/10. After the pick, the bowl will have 5 red marbles and 6 blue marbles.

For the second pick, the probability of selecting a red marble is 5/11. After the pick, the bowl will have 6 red marbles and 6 blue marbles. Finally, for the third pick, the probability of selecting a red marble is 6/12, which simplifies to 1/2.

To find the probability of all three picks being red, we multiply the probabilities of each pick: (4/10) * (5/11) * (1/2) = 2/55.

Therefore, the probability of selecting a red marble on each of the three picks is 2/55.

[tex]3\frac{3}{10} = \frac{33}{10}[/tex]

Step-by-step explanation:

For a given data set, the equation of the least squares regression line will always pass through the point [tex]\((\bar{x}, \bar{y})\),[/tex] where [tex]\(\bar{x}\)[/tex] is the mean of the x-values and[tex]\(\bar{y}\)[/tex] is the mean of the y-values.

The least squares regression line minimizes the sum of squared differences between the observed y-values and the values predicted by the line. The equation of the line is given byy = mx + b, where m is the slope and bis the y-intercept. The slopem and y-intercept b are determined by formulas involving the means[tex](\(\bar{x}\)[/tex] and [tex]\(\bar{y}\))[/tex]and other statistical measures from the data set.

The specific formulas for the least squares regression line are:

[tex]\[ m = \frac{\sum_{i=1}^{n} (x_i - \bar{x})(y_i - \bar{y})}{\sum_{i=1}^{n} (x_i - \bar{x})^2} \]\[ b = \bar{y} - m\bar{x} \][/tex]

It can be observed from the formulas that when [tex]\(x = \bar{x}\)[/tex], the corresponding y value is[tex]\(\bar{y}\)[/tex]. Therefore, the least squares regression line passes through the point[tex]\((\bar{x}, \bar{y})\)[/tex]. This point represents the centroid of the data set and ensures that the line adequately represents the overall trend of the data.

Answer:

V = 11.3 ft^3

Step-by-step explanation:

The volume of a cone is given by one third of its base area multiplied by its height:

V = (1/3)*A*h

This cone have a circular base, so the base area is given by

A = pi*r^2, where r is the base radius

The length of a circumference is given by L = 2*pi*r

the base circumference is 5 ft, so we can calculate the base radius:

5 = 2*pi*r -> r = 5/(2*pi)

Using this value, we can calculate A:

A = pi*r^2 = pi * [5/(2*pi)]^2 = pi * 25/(4*pi^2) = 25/(4*pi) = 1.9894

Now, we use the formula to calculate the volume:

V = (1/3)*A*h = (1/3) * 1.9894 * 17 = 11.2735 ft^3

rounding it, we have V = 11.3 ft^3

Answer:

The probability of selecting a  person which is  self-employed but not married equals 1/8.

Step-by-step explanation:

Here, the given survey says:

Total number of people surveyed = 248

Number of people married = 156

The number of people are self employed = 70

Now, 25% of people who are married are SELF EMPLOYED.

Now, calculating 25% of 156 , we get:

[tex]\frac{25}{100} \times 156 = 39[/tex]

⇒ out of total 156 married people, 39 are self employed.

So, number of  self employed people but  not married

= Self employed people - Self employed people PLUS  married

=  70  -  39   =  31.

So, the probability that the person selected will be self-employed but not married = [tex]\frac{\textrm{The total number of people self-employed but not married}}{\textrm{Total Number of people}}[/tex] =  [tex]\frac{31}{248} = \frac{1}{8}[/tex]

Hence The probability of selecting a  person which is  self-employed but not married equals 1/8.

Option A. 264 ft² ; 4 gallons

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

From the picture attached,

Area of the barn to be painted = Area of the (rectangular base + Triangular top) - Area of the window

Area of the rectangular base = 12 × 18

                                                = 216 ft²

Area of the triangular top = [tex]\frac{1}{2}(\text{Base}\times \text{Height})[/tex]

                                          = [tex]\frac{1}{2}(12)(28-18)[/tex]

                                          = 60 square feet

Area of the window = 3 ft × 4 ft

                                 = 12 ft²

Total area to be painted = 216 + 60 - 12

                                         = 264 ft²

∵ 70 square feet of the barn is covered by the amount of paint = 1 gallon

∴ 1 square feet will be covered by the amount = [tex]\frac{1}{70}[/tex] gallons

∴ 264 square feet will be painted by = [tex]\frac{264}{70}[/tex]

                                                             = 3.77 gallons

                                                             ≈ 4 gallons

The only x-intercept is x = 1

Step-by-step explanation:

The equation is:

[tex]r(x)=\frac{x-1}{x+4}[/tex]

We can substitute y for r(x), to write in the notation:

[tex]r(x)=\frac{x-1}{x+4}\\y=\frac{x-1}{x+4}[/tex]

To get y-intercept, we put x = 0

and

To get x-intercept, we put y =0

We want to find x-intercepts here, so we substitute 0 into y and solve for x. Shown below:

[tex]y=\frac{x-1}{x+4}\\0=\frac{x-1}{x+4}\\0(x+4)=x-1\\0=x-1\\x=1[/tex]

The only x-intercept is x = 1

The equation representing the scenario is [tex]x+\frac{5}{4}-\frac{3}{4} = \frac{21}{4}[/tex].

Step-by-step explanation:

Given:

Amount of food in the container = [tex]x \ cups[/tex]

Amount of food added in the container = [tex]2\frac12\ cups[/tex]

We will now convert the mixed fraction into Improper fraction by Multiplying the whole number part by the fraction's denominator and then add that to the numerator  and then write the result on top of the denominator.

[tex]2\frac12\ cups[/tex] can be rewritten as [tex]\frac{5}{4}\ cups[/tex]

Amount of food added in the container =  [tex]\frac{5}{4}\ cups[/tex]

Amount of food removed from container to feed dog  = [tex]\frac34 \ cups[/tex]

Amount of food remaining = [tex]5\frac{1}{4} \ cups[/tex]

[tex]5\frac{1}{4} \ cups[/tex] can be Rewritten as = [tex]\frac{21}{4}\ cups[/tex]

Amount of food remaining =  [tex]\frac{21}{4}\ cups[/tex]

We need to write the equation for above scenario.

Solution:

Now we can say that;

Amount of food remaining is equal to Amount of food in the container plus Amount of food added in the container minus Amount of food removed from container to feed dog.

framing in equation form we get;

[tex]x+\frac{5}{4}-\frac{3}{4} = \frac{21}{4}[/tex]

Hence the equation representing the scenario is [tex]x+\frac{5}{4}-\frac{3}{4} = \frac{21}{4}[/tex].

Answer:

Therefore, we have 36 different treatment groups.

Step-by-step explanation:

We know that the 7 subjects are selected from the 9 that are​ available, and the 7 selected subjects are all treated at the same​ time.

We calculate how many different treatment groups are​ possible.

We get:

[tex]C_7^9=\frac{9!}{7!(9-7)!}=\frac{9\cdot 8\cdot 7!}{7!\cdot 2\cdot 1}= 36[/tex]

Therefore, we have 36 different treatment groups.

The computer algorithm executes twice as many operations when the input size increases by 1. By using this information and calculating the operations for each input size, we find that it executes 26,624 operations for an input size of 26.

To find out how many operations the computer algorithm executes when it is run with an input of size 26, we can use the given information. The algorithm executes twice as many operations when the input size increases by 1. So, if it executes 7 operations for an input size of 1, it would execute 14 operations for an input size of 2, 28 operations for an input size of 3, and so on.

Since the algorithm executes twice as many operations for each increase in input size, we can see that it follows a pattern of doubling. We can calculate the number of operations for an input size of 26 by doubling the number of operations for an input size of 25. Continuing this calculation, we get:

Input Size 1: 7 operations
Input Size 2: 14 operations
Input Size 3: 28 operations
...

Input Size 25: 13,312 operations
Input Size 26: 26,624 operations

Product of the point values of the removed beads = 147000

So, the possible way is given by

[tex]2^3\times 3\times 5^3\times 7^2=147000[/tex]

Since no other beads is a multiple of 7.

So, there must be two red beads removed.

Hence, Option 'D' is true.

Hence correct option is b with 4 colors.

Step by-step explanation:

We are given a graph in which we need to color every vertex or node such that no adjacent vertex or node should have the same color, ex:- If color of node B is blue than it's adjacent vertex A and D must not have the same blue color. Now, Let's start coloring of graph :

Color vertex A as red : Now, it's adjacent vertex as B,C,D,E must not have red color we know this!.

Color vertex B as blue: Now, it's adjacent vertex A and D must not have blue color!

Color vertex C as blue:  Now, it's adjacent vertex A,E and D must not have blue color!

Color vertex D as green:  Now, it's adjacent vertex A,B,C and E must not have green color!

Color vertex E as purple:  Now, it's adjacent vertex C and D must not have purple color!

Hence correct option is b with 4 colors.

Answer:

Probability that at least three would be yellow = 0.556 .

Step-by-step explanation:

We are given that In Europe, 53% of flowers of the reward less orchid, Dactylorhiza sambucina are yellow.

The Binomial distribution probability is given by;

P(X = r) = [tex]\binom{n}{r}p^{r}(1-p)^{n-r}[/tex] for x = 0,1,2,3,.......

Here, n = number of trials which is 5 in our case

          r = no. of success which is at least 3 in our case

         p = probability of success which is probability of yellow flower of

                0.53 in our case

So, P(X >= 3) = P(X = 3) + P(X = 4) + P(X = 5)

      = [tex]\binom{5}{3}0.53^{3}(1-0.53)^{5-3} + \binom{5}{4}0.53^{4}(1-0.53)^{5-4} + \binom{5}{5}0.53^{5}(1-0.53)^{5-5}[/tex]

      = [tex]10*0.53^{3}(0.47)^{2} + 5*0.53^{4}(0.47)^{1} + 1*0.53^{5}(0.47)^{0}[/tex]

      = 0.556

Therefore, the probability that at least three would be yellow is 0.556 .        

The interest expense for West Company in Year 1 is approximately $1,141, calculated using the principal of $38,000, the annual interest rate of 9%, and the time from the loan date to the end of Year 1, which is ⅓ of a year.

The student's question involves calculating the amount of interest expense to be reported on the income statement for West Company in Year 1, given that the company borrowed $38,000 on September 1, Year 1 at an annual interest rate of 9% with an 18-month term. To calculate the interest expense for Year 1, we need to consider the amount of time from the loan initiation date (September 1, Year 1) to the end of Year 1 (December 31, Year 1), which is 4 months or ⅓ of a year.

Interest Expense calculation:

Interest Expense = Principal Amount × Annual Interest Rate × Time in Years

Interest Expense for West's Year 1 = $38,000 × 9% × (⅓)

Interest Expense for West's Year 1 = $38,000 × 0.09 × 0.3333

Interest Expense for West's Year 1 = $1,141 (approximately)

Therefore, the interest expense appearing on West's Year 1 income statement would be approximately $1,141.

                          [tex]N(t_{1} )[/tex] = 20,000

         and [tex]N(t_{1}+10 )=100,000[/tex]

(a) For population growth

[tex]N(t)=N_{0}e^{kt}=10000e^{kt}[/tex]

[tex]N(t_1)=10,000e^{kt_1}=20,000[/tex]

[tex]e^{kt}=2[/tex]

[tex]ln(e^{kt_1})=ln(2)[/tex]

[tex]kt_1=ln(2)[/tex]

[tex]t_{1}=\frac{ln2}{k}[/tex] ----------(1)

[tex]N(t_1+t_{10})=100,000[/tex]

[tex]100,000=10,000e^{k(t_1+10)}[/tex]

[tex]10=e^{k(t_1+10)}[/tex]

[tex]ln10=ln[e^{k(t_1+10)}][/tex]

[tex]k(t_1+10)=ln10[/tex]

[tex]k(t_1)=ln10-10k[/tex]

[tex]t_1=\frac{ln10-10k}{k}[/tex] ----------(2)

from equation (1) and (2)

[tex]\frac{ln_2}{k}=\frac{ln10-10k}{k}[/tex]

[tex]ln10-ln2=10k[/tex]

[tex]k=\frac{ln5}{10}[/tex]

so expression will be

[tex]N(t)=10000e^{(\frac{ln5}{10})t }[/tex]

(b) for t = 20

    [tex]N_{(20)}=10,000e\frac{ln5}{10}\times 20[/tex]

             =  [tex]10,000\times e^{2ln5}[/tex]

            = 10,000 × 25

            = 25,000

(c) Since [tex]t_1=\frac{ln2}{k}[/tex]   [from equation (1)]

                  [tex]=\frac{ln2}{\frac{ln5}{10} }[/tex]

                  [tex]=\frac{ln2}{ln5}\times 10[/tex]

                  = 4.3068

                 = 4.3068 min.

Answer:

See explanation

Step-by-step explanation:

The given functions are:

[tex]f(x) = {x}^{2} - 5[/tex]

and

[tex]g(x) = f(x - 7)[/tex]

We substitute x-7, wherever we see x in f(x) to obtain:

[tex]g(x) = {(x - 7)}^{2} - 5[/tex]

This means g(x) is obtained by shifting f(x) 7 units to the right.

Also we can say g(x) is obtained by shifting the parent quadratic function, 7 units left and 5 units down.

You have not provided the options, but I hope this explanation helps you check the correct answers.

Answer:

#13:  0

#14:  -99

Step-by-step explanation:

#13:  g(x) = 2x^3 - 5x^2 + 4x - 1;  x = 1

Step 1:  Substitute 1 for x

2(1)^3 - 5(1)^2 + 4(1) - 1

2(1) - 5(1) + 4 - 1

2 - 5 + 4 - 1

0

Answer:  0

#14:  h(x) = x^4 + 7x^3 + x^2 - 2x - 6;  x = -3

Step 1:  Substitute -3 for x

(-3)^4 + 7(-3)^3 + (-3)^2 - 2(-3) - 6

81 + 7(-27) + 9 + 6 - 6

81 - 189 + 9 + 6 - 6

-99

Answer:  -99

Answer:

The answer to your question is Perimeter = 24.1 u

Step-by-step explanation:

Data

F (-4, 5)

G (1, 10)

H (-9, 10)

Process

1.- Calculate the distance from FG

dFG = [tex]\sqrt{(1 + 4)^{2} + (10 - 5)^{2}}[/tex]

dFG = [tex]\sqrt{5^{2} + 5^{2}}[/tex]

dFG = [tex]\sqrt{25 + 25}[/tex]

dFG = [tex]\sqrt{50}[/tex]

dFG = [tex]5\sqrt{2}[/tex] = 7.07

2.- Calculate the distance from GH

dGH = [tex]\sqrt{(-9 - 1)^{2} + (10 - 10)^{2}}[/tex]

dGH = [tex]\sqrt{10^{2} + 0^{2}}[/tex]

dGH = [tex]\sqrt{100}[/tex]

dGH = 10

3.- Calculate the distance from FH

dFH = [tex]\sqrt{(-9 + 4)^{2} + ( 10 - 5)^{2}}[/tex]

dFH = [tex]\sqrt{-5^{2}+ 5^{2}}[/tex]

dFH = [tex]\sqrt{25 + 25}[/tex]

dFH = [tex]\sqrt{50}[/tex]

dFH = [tex]5\sqrt{2}[/tex] = 7.07

4.- Calculate the perimeter

Perimeter = 7.07 + 10 + 7.07

                 = 24.1 units
