© Mario buys one of the newspapers at random. What is the probability that it has
reviewed both performances?
4 >

Answers

Answer 1

The probability that the newspaper Mario buys has reviewed both performances, given that he buys the first newspaper, is 0.72 or 72%.

a) Let's assume the probability of the first newspaper reviewing his performance is 2/7 and the probability of the second newspaper reviewing his performance is 5/7. The probability of both papers reviewing his performance is (2/7) * (5/7) = 10/49.

b)Since Clarissa buys both newspapers, there are two scenarios: either the first newspaper reviews her performance and the second one doesn't, or the second newspaper reviews her performance and the first one doesn't. The probability of only one paper reviewing her performance is 2 * (3/7) * (4/7) = 24/49.

c) If Mario buys one newspaper at random, there is a 2/7 chance that he buys the first newspaper and a 5/7 chance that he buys the second newspaper. Since each newspaper has reviewed one performance, the probability that the newspaper he buys has reviewed both performances is (2/7) * (5/7) = 10/49.

Two airplanes leave an airport at the same time and travel in opposite directions. One plane travels 61 km/h slower than the other. If the two planes are 10458 kilometers apart after 6 hours, what is the rate of each plane?

Answers

Answer:

Step-by-step explanation:

Distance traveled by both the planes in 6hrs=10458

let x, x+61 be the speeds of both the planes

Distance traveled = speed*time

10458=(x*6) + [(x+61)*6}

10458=6x+(6x+366)

12x=10092

x=841

Answer:

one plane's rate = 841km/h. other plane's rate = 902km/h

Step-by-step explanation:

Let's say one plane goes to the left and the other to the right.

call the planes L and R, respectively.

L travels at x km/h. R travels at (x + 61)km/h.

after 6 hours, L has travelled 6xkm. R has travelled 6(x + 61)

= (6x + 366)km.

they are 10458 km apart.

so, 6x + 6x + 366 = 10458

12x = 10092

x = 841.

plane L travels at rate of 841 km/h.

plane R travels at rate of 841 + 61 = 902 km/h.

Answers

The answers are 1) 7/6, 2) 11/15, 3) 11/12 and 4) 3/5.

Given are fractions we need to operate them as mentioned.

1) 1/2 + 2/3 =

To add fractions with different denominators, you need to find a common denominator.

In this case, the common denominator is 6 because both 2 and 3 divide evenly into 6.

Let's convert both fractions to have a denominator of 6:

1/2 = (1/2) x (3/3) = 3/6

2/3 = (2/3) x (2/2) = 4/6

Now that both fractions have a common denominator, you can add them:

3/6 + 4/6 = 7/6

So, 1/2 + 2/3 = 7/6.

Similarly,

2) 9/10 - 1/6 =

Let's convert both fractions to have a denominator of 30:

9/10 = (9/10) x (3/3) = 27/30

1/6 = (1/6) x (5/5) = 5/30

Now we can subtract the fractions:

27/30 - 5/30 = (27 - 5)/30 = 22/30 = 11/15

3) 3/4 + 3/18 =

Let's convert both fractions to have a denominator of 36:

Now that both fractions have the same denominator, we can add them together:

(3/4) x (9/9) = 27/36

(3/18) x (2/2) = 6/36

27/36 + 6/36 = 33/36 = 11/12

4) 3/4 - 3/20 =

LCM of 4 and 20 is 20. We can convert both fractions to have a denominator of 20:

3/4 = (3/4) x (5/5) = 15/20

3/20 remains as it is.

Now, we can subtract the two fractions:

15/20 - 3/20 = (15 - 3) / 20 = 12/20 = 3/5

Hence the answers are 1) 7/6, 2) 11/15, 3) 11/12 and 4) 3/5.

The dimensions of a rectangular plot of ground is 12m by 10m. A rectangular pool is dug at the centre of the plot surrounded by a path of uniform width. If the area of the pool is 2/3 of the area of the plot, find the width of the path

Answers

To find the width of the path surrounding the rectangular pool, we can start by calculating the area of the rectangular plot and the area of the pool.

Given:

Dimensions of the rectangular plot: 12m by 10m

Step 1: Calculate the area of the rectangular plot

Area of the plot = length × width

Area of the plot = 12m × 10m = 120m²

Step 2: Calculate the area of the pool

Let's assume the width of the path surrounding the pool is denoted by "x."

The dimensions of the pool will be smaller than the plot by twice the width of the path.

Length of the pool = 12m - 2x

Width of the pool = 10m - 2x

Area of the pool = (length of pool) × (width of pool)

Area of the pool = (12m - 2x) × (10m - 2x)

Given that the area of the pool is 2/3 of the area of the plot, we can set up the equation:

(12m - 2x) × (10m - 2x) = (2/3) × 120m²

Step 3: Solve the equation for x

Expand the equation and simplify:

(120m - 24xm - 20xm + 4x²) = (2/3) × 120m²

120m - 44xm + 4x² = (2/3) × 120m²

Multiply both sides by 3 to remove the fraction:

360m - 132xm + 12x² = 240m²

Rearrange the equation to get it in the standard form of a quadratic equation:

12x² - 132xm + (240m² - 360m) = 0

Simplify further:

12x² - 132xm + 120m(2m - 3) = 0

Now, we can solve this quadratic equation for x using factoring, completing the square, or the quadratic formula. However, it seems that there might be an error in the problem statement or calculation because there is a missing value for the length "m" in the given information.

Please double-check the given dimensions or provide any missing information so that I can assist you further in finding the width of the path surrounding the pool.

Given that vectors AB (20, 10) ,BC (16, -14) and point C = (12, -8) , find the cordinates of the point A.​

Answers

The coordinates of point A are,

A = (-24, -4).

Now, For the coordinates of point A, we use the fact that

⇒ vector AB + vector BC = vector AC.

So, We get;

AB + BC = (20, 10) + (16, -14)

             = (36, -4)

Now, we know that vector AC is equal to (36, -4)

since vector BC points from B to C.

We also know that point C has coordinates (12, -8).

So, to find the coordinates of point A, we can use the formula:

A = C - AC

Substituting in the values we have:

A = (12, -8) - (36, -4) = (-24, -4)

Therefore, the coordinates of point A are (-24, -4).

Elizabeth brought a box of donuts to share. There are​ two-dozen (24) donuts in the​ box, all identical in​ size, shape, and color are​ jelly-filled, are​ lemon-filled, and are​ custard-filled. You randomly select one​ donut, eat​ it, and select another donut. Find the probability of selecting two ​-filled donuts in a row.

Answers

The probability of selecting a matching donut on the second try is 7/23.There is a 10.14% chance of selecting two ​-filled donuts in a row from Elizabeth's box of two dozen donuts.

To find the probability of selecting two ​-filled donuts in a row, we first need to determine the total number of donut combinations.

Since there are three different fillings, there are three possible outcomes for the first donut and three possible outcomes for the second donut. Therefore, the total number of combinations is 3 x 3 = 9.

Next, we need to determine the number of combinations where both donuts are filled. There are 24 donuts in the box, and eight of them are jelly-filled, eight are lemon-filled, and eight are custard-filled.

So, the probability of selecting a filled donut on the first try is 8/24, or 1/3. Once the first donut is eaten, there are only 23 donuts left, and seven of them are filled with the same type of filling as the first donut.

To find the probability of selecting two ​-filled donuts in a row, we multiply the probabilities of each event. So, the probability of selecting two matching ​-filled donuts in a row is (1/3) x (7/23) = 7/69, or approximately 0.1014.

Use the image of circle B to answer the question. Choose a measure for angel ADC. Use your choice for angle ADC to determine the measure of arc ADC

Answers

The length of arc ADC is 29.33 units.

Let us take the measure of angle ADC to be 60 degrees.

We know that,

the angle formed by an arc on the center of a circle is twice the magnitude of the angle formed by the same arc on the circumference of the circle.

Now, arc AC forms angle ABC at the center and angle ADC at the circumference.

∴ angle ABC = 2 × angle ADC

                     = 2 × 60 degrees

                     = 120 degrees

Or, the magnitude of reflex angle ABC = 360 - 120 degrees.

                                                                 = 240 degrees.

Also, the circumference of the circle = 2πr

                                                       = 2 × 22/7 × 7

                                                       = 44 units.

∴ the length of arc ADC = magnitude of reflex angle ADC/total angle × circumference

                                         = 240/360 × 44

                                         = 29.33 units.

Darryl is using small unit cubes to make a big cube that is 3 units high. To complete the big cube, Darryl would need to determine the total number of small unit cubes required.

A cube is a three-dimensional figure that has six faces, eight vertices, and twelve edges of equal length. The small cubes are placed one on top of the other, in layers, to create a larger cube.

Therefore, if the big cube is 3 units high, there will be three layers of small cubes in the vertical direction, each with the same dimensions as the base.

The base of the cube would be a square, and each side would have three small cubes lined up next to each other.

So, the base of the cube would have dimensions of 3 units by 3 units. To fill one layer of the cube, Darryl would need 3 x 3 x 1 = 9 small cubes.

Please help I’ll mark you as brainliest if correct!

Answers

Answer:

x = 110°

y = 110°

z = 70°

Explanation:

A rhombus' interior angles (the ones we're looking for) always equal to 360°.

A rhombus also has the same degree as the side opposite of it, so since z is the opposite side of the current 70°, we also know that z is equal to 70°.

This also means that x and y are equal to each other, so to find these sides, we need to subtract the other known values from 360.

70° + 70° = 140°

360° - 140° = 220°

Since the amount we have left is 220°, and our last 2 values are equal to each other, we can divide this by 2 in order to find their individual degrees.

220/2 = 110°

Both x and y are equal to 110°.

Find the coordinates of the intersection of the diagonals of ABCD with vertices 4(0, 3), B(10,3).c(8,-1), and D(-2,-1).
The coordinates of the intersection of the diagonals are CD.

Answers

The diagonals of ABCD do not intersect. There is no intersection point for the diagonals CD.

To discover the coordinates of the intersection of the diagonals of ABCD, we want to calculate the factor of intersection between the line section connecting factors C and D and the line section connecting factors A and B.

Given the coordinates:

A(0, 3)

B(10, 3)

C(8, -1)

D(-2, -1)

We first locate the equations of the two lines:

Line AD:

The slope of line AD can be calculated as (change in y) / (change in x):

m_AD = (3 - (-1)) / (0 - (-2))

= four / 2

= 2

Using the point-slope form, we have the equation of line AD as:

y - three = 2(x - 0)

y - three = 2x

Line BC:

The slope of line BC can be calculated as (change in y) / (change in x):

m_BC = (3 - (-1)) / (10 - 8)

= four / 2

= 2

Using the point-slope form, we have the equation of line BC as:

y - three = 2(x - 10)

y - three = 2x - 20

Now, we have the equations:

y = 2x (Equation for line AD)

y = 2x - 17 (Equation for line BC)

To discover the intersection point, we set these two equations equal to every other:

2x = 2x - 17

This equation is contradictory and has no solution, indicating that the strains AD and BC are parallel and do now not intersect.

What size sample should be obtained if he wishes the estimate to be within 4 percentage points (in other words the margin of error is 0.04) with 95% confidence if he uses a previous estimate of 27.5% (round up to the next integer).

Answers

The researcher should obtain a sample size of 1700 to estimate the percentage of adults who support abolishing the penny with a 95% confidence level and a margin of error of 4 percentage points.

To determine the sample size needed to estimate the percentage of adults who support abolishing the penny with a 95% confidence level and a margin of error of 4 percentage points, we can use the following formula:

Sample size = (Z^2 * P * (1 - P)) / E^2

Where:

Z = Z-score for the desired confidence level (for 95% confidence level, Z ≈ 1.96)

P = Estimated proportion (expressed as a decimal)

E = Margin of error

Given:

Estimated proportion (P) = 27.5% (0.275 as a decimal)

Margin of error (E) = 0.04

Substituting the values into the formula:

Sample size = (1.96^2 * 0.275 * (1 - 0.275)) / 0.04^2

Sample size = (3.8416 * 0.275 * 0.725) / 0.0016

Sample size ≈ 1699.63

Rounding up to the next integer, the required sample size is 1700.

Therefore, the researcher should obtain a sample size of 1700 to estimate the percentage of adults who support abolishing the penny with a 95% confidence level and a margin of error of 4 percentage points.

select one topic in the caps document for a grade 4 class , illustrate how you will teach it using the meaning of doing mathematics: the topic should come from the content area : data handling​

Answers

ANSWER:

Topic: Data Handling - Collecting and Representing Data

Objective: Students will learn how to collect and represent data using different methods and graphical representations.

Teaching Approach: Meaning of Doing Mathematics

1. Introduction (5 minutes):

- Begin the lesson by asking students to think about why data is important and how it can be used in everyday life.

- Engage students in a discussion about the different types of data they encounter in their daily lives (e.g., favorite colors, sports, ice cream flavors, etc.).

2. Data Collection Activity (15 minutes):

- Explain to students that they will collect data on a topic of their choice, such as favorite animals, hobbies, or TV shows.

- Provide each student with a data collection sheet and ask them to survey their classmates to gather data.

- Emphasize the importance of asking clear and specific questions and recording responses accurately.

3. Data Representation (20 minutes):

- Once the data is collected, guide students in representing the data using different methods.

- Discuss the importance of selecting appropriate representations based on the type of data collected (e.g., tally marks, bar graphs, pictographs).

- Model how to create a bar graph or pictograph using the collected data on the board or chart paper.

- Encourage students to interpret the graphs, identify patterns, and draw conclusions from the data represented.

4. Analyzing and Interpreting Data (15 minutes):

- Engage students in a class discussion about the different patterns and trends they notice in the data represented.

- Guide them in making comparisons, finding the most common and least common responses, and discussing the significance of the findings.

- Encourage students to express their thoughts and reasoning behind their observations.

5. Application and Reflection (10 minutes):

- Provide students with additional data sets or ask them to create their own data sets to practice representing and interpreting data.

- Ask students to reflect on the importance of collecting and representing data accurately and how it helps in understanding and making informed decisions.

6. Wrap-up and Extension (5 minutes):

- Summarize the key concepts covered in the lesson and highlight the importance of data handling in real-life situations.

- Assign a small project or task where students can apply their data collection and representation skills in a different context.

By adopting the "Meaning of Doing Mathematics" approach, students actively engage in the process of collecting and representing data. They develop a deeper understanding of the purpose and significance of data handling in real-life situations. The emphasis is on hands-on activities, critical thinking, and making connections between mathematics and their everyday experiences.

A company takes care of cats and dogs overnight when their owners are out of town. The company charges $18 per cat per night and $30 per dog per night. On Saturday
of 16 cats and dogs. The system of equations shows the total amount the company charged on Saturday night for the number of cats, the number of dogs, y, that were taken care of.
X+ y = 16
18x + 30y = 432
How many cats did the company take care of on Saturday night?

Answers

The number of cats that company take to care of on Saturday night = 72.

The given system of equation is,

       x + y = 16     .....(i)  

18x + 30y = 432  .....(ii)

Where x represents the number of dog

And y represents the number of cat

One strategy for solving a system of linear equations is the elimination method. To get the equation in one variable, either add or subtract the equations. If the coefficients of one of the variables are the same and their signs are opposite, we can use the equation to delete the variable. Similarly, if the coefficients of one of the variables are the same, as well as their sign, we can subtract the equation to yield the equation in one variable.

Now  multiply 18 with (i) we get,

18x + 18y = 288    .....(iii)

Subtract (iii) from (ii)

⇒ 2y = 144

⇒   y = 72

Hence,

there were 72 cats.

√(126539.1 / 171) =

To calculate the appropriate measure of skewness for the given data, we can use the formula:

Skewness = [3(mean - median)] / standard deviation

First, we need to find the mean, median, and standard deviation of the data set.

To find the mean, we use the formula:

mean = (Σ(xi * fi)) / N

where xi is the midpoint of each class, fi is the frequency of each class, and N is the total number of workers.

Calculating the midpoint of each class:

5, 15, 25, 35, 45, 55

Multiplying each midpoint by its corresponding frequency, and summing the results:

(5*10) + (15*12) + (25*25) + (35*35) + (45*40) + (55*50) = 6300

Dividing by the total number of workers:

6300 / 172 = 36.63

So the mean is approximately 36.63.

To find the median, we need to first calculate the cumulative frequency for each class:

Class: 0-10 10-20 20-30 30-40 40-50 50-60

Frequency: 10 12 25 35 40 50

Cumulative: 10 22 47 82 122 172

The median is the middle value of the data set, which is the 86th value in this case. Looking at the cumulative frequencies, we see that the median falls in the 30-40 class. So the median class is 30-40, with a cumulative frequency of 82. The width of the class interval is 10, and the frequency of the median class is 35.

Using the formula:

median = L + [(N/2 - CF) / f] * w

where L is the lower limit of the median class, N is the total number of workers, CF is the cumulative frequency of the class preceding the median class, f is the frequency of the median class, and w is the width of the median class interval.

Substituting in the values, we get:

median = 30 + [(86/2 - 82) / 35] * 10 = 31.71

So the median is approximately 31.71.

To find the standard deviation, we can use the formula:

standard deviation = √[Σ(fi * (xi - mean)²) / (N - 1)]

where xi and fi are as before, mean is the mean of the data set, and N is the total number of workers.

Calculating the squared deviation of each midpoint from the mean, and multiplying by the frequency of each class:

[(5 - 36.63)² * 10] + [(15 - 36.63)² * 12] + [(25 - 36.63)² * 25] + [(35 - 36.63)² * 35] + [(45 - 36.63)² * 40] + [(55 - 36.63)² * 50] = 126539.1

Dividing by (N-1) and taking the square root:

√(126539.1 / 171) =
