Answers

Answer 1

The probability that less than 8.4% of the individuals in the sample hold multiple jobs is approximately 0.0681 or 6.81%.

What is Probability ?

Probability can be defined as ratio of number of favourable outcomes and total number outcomes.

To determine whether it is appropriate to use the normal approximation, we need to check whether the conditions for using the normal distribution are met.

We can use the following criteria:

The sample size is large enough: n × p ≥ 10 and n × (1 − p) ≥ 10

The observations are independent

Here, we are given that the sample size is n = 66. To check the first condition, we need to find the expected number of individuals who hold multiple jobs in the sample, which is given by:

np = 0.12 × 66 = 7.92

n(1-p) = 66 - 7.92 = 58.08

Both np and n(1-p) are greater than or equal to 10. So, the sample size is large enough and the first condition is met.

Additionally, we can assume that the observations are independent since the sample is random and represents less than 10% of the population of employed adults in the United States.

Therefore, it is appropriate to use the normal approximation.

To find the probability that less than 8.4% of the individuals in the sample hold multiple jobs, we need to standardize the sample proportion using the formula:

z = (p'- p) / [tex]\sqrt{(p(1-p) / n)}[/tex]

where p' is the sample proportion, p is the population proportion (0.12), n is the sample size (66), and sqrt represents the square root.

Substituting the values, we get:

z = (0.084 - 0.12) / [tex]\sqrt{((0.12)(1-0.12) / 66)}[/tex] = -1.496

Using a standard normal distribution table, we can find that the probability of z being less than -1.496 is approximately 0.0681.

Therefore, the probability that less than 8.4% of the individuals in the sample hold multiple jobs is approximately 0.0681 or 6.81%.

What is a circle?

A circle is a two-dimensional geometric figure that consists of all the points in a plane that are equidistant from a given point called the center. The distance from the center to any point on the circle is called the radius, which is denoted by the letter "r".

To find the cardinality of n(A∩B∩C^c), we need to know the number of elements that are in the intersection of A and B but not in C.

One way to approach this is to use the principle of inclusion and exclusion. This states that:

n(A ∪ B ∪ C) = n(A) + n(B) + n(C) - n(A ∩ B) - n(A ∩ C) - n(B ∩ C) + n(A ∩ B ∩ C)

We can rearrange this formula to solve for n(A ∩ B ∩ C^c):

n(A ∩ B ∩ C^c) = n(A ∩ B) - n(A ∩ B ∩ C) - n(B ∩ C) + n(A ∩ C) + n(B) + n(C) - n(A)

Plugging in the values we have been given, we get:

n(A ∩ B ∩ C^c) = 4 - 3 - 9 + 7 + 11 + 15 - 10

Simplifying this expression, we get:

n(A ∩ B ∩ C^c) = 15

Therefore, there are 15 elements in the intersection of sets A and B but not in set C.

The conditional relative frequency that a student rides the bus, given that the student is in middle school is 0.16 / 0.96 ≈ 0.17.

Describe conditional relative frequency ?

Conditional relative frequency is a statistical measure that describes the proportion or percentage of a specific group or category within a subset of data. It is calculated by dividing the frequency of the specific category in the subset by the frequency of the total subset.

To find the conditional relative frequency that a student rides the bus, given that the student is in middle school, we need to divide the frequency of middle school students who ride the bus by the total number of middle school students.

From the table, we see that the frequency of middle school students who ride the bus is 0.16. The total number of middle school students is the sum of the frequencies in the first row, which is 0.20 + 0.16 + 0.12 + 0.48 = 0.96.

So, the conditional relative frequency that a student rides the bus, given that the student is in middle school is:

0.16 / 0.96 ≈ 0.17

Rounded to the nearest hundredth, the answer is 0.17. Therefore, about 17% of middle school students ride the bus.

Among the given equations, the equation E. y = 5x - 3x + 4 is the only equation that is in the form y = mx + b.

What is linear equation ?

A linear function is defined as a function that has a constant rate of change, meaning that as x increases by a certain amount, y also increases by a certain amount. Therefore, the equation that defines y as a linear function of x is of the form y = mx + b, where m is the slope and b is the y-intercept.

Among the given equations, the equation E. y = 5x - 3x + 4 is the only equation that is in the form y = mx + b. By combining like terms, we can simplify it to y = 2x + 4. This equation has a constant rate of change of 2, which means that for every 1 unit increase in x, y will increase by 2 units.

The other equations are not linear functions because they either have an x² term, which causes a non-constant rate of change, or they have multiple variables, which means that changes in x will not produce a consistent change in y.

Therefore, the answer is E. y = 5x - 3x + 4.

Answer: D. Square

Step-by-step explanation:

The shape created by the cross section of the cut through a square pyramid is a square.

To see why, imagine the pyramid sitting on a table with its square base flat against the surface. The cut goes through the vertex, which is the point at the top of the pyramid. Since the cut is perpendicular to the base, it divides the pyramid into two smaller pyramids with congruent, but not identical, bases. Each of these smaller pyramids has a triangular base that is an isosceles right triangle. The two triangles share a common hypotenuse, which is the line of the cut.

The cross section of the cut is the shape formed where the two triangles meet along the hypotenuse. Since both triangles are congruent and the hypotenuse is the same for both, the cross section is a square. The sides of the square are equal to the base of the original pyramid, which is one of the legs of the isosceles right triangles formed by the cut. Therefore, the answer is D, a square.

A water cooler springs a leak and empties in 2 minutes. The graph below shows the rate at which water leaks from the cooler as a function of time.

Answers

The amount of water that was in the cooler before it started leaking was 6 gallons.

Describe Integration?

Integration is a mathematical process that involves finding the integral of a function. It is the reverse operation of differentiation, which involves finding the derivative of a function. The integral of a function is a measure of the area under the curve of the function, between two given limits of integration.

The graph shows the rate at which water leaks from the cooler as a function of time, which means that the y-axis represents the rate of leakage in gallons per minute (gal/min), and the x-axis represents the time in minutes.

Since we know that the cooler emptied in 2 minutes, we can integrate the leakage rate over the time interval [0, 2] to find the total amount of water that leaked out:

Total amount of water leaked = ∫[0,2] leakage rate(t) dt

The leakage rate is given by the graph, which consists of a straight line connecting two points: (0,6) and (2,0). We can express this line as a linear equation in slope-intercept form:

leakage rate(t) = mt + b

where m is the slope of the line and b is the y-intercept. To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0,6) and (x2, y2) = (2,0). Plugging in the values, we get:

m = (0 - 6) / (2 - 0) = -3

So the equation of the line is:

leakage rate(t) = -3t + 6

Now we can integrate this equation over the time interval [0, 2] to get the total amount of water leaked:

Total amount of water leaked = ∫[0,2] (-3t + 6) dt

= [-3t²/2 + 6t] from 0 to 2

= (-3(2)²/2 + 6(2)) - (-3(0)²/2 + 6(0))

= (6 - 0) - (0 - 0)

= 6 gallons

Therefore, the amount of water that was in the cooler before it started leaking was 6 gallons.

Find the surface area of the triangular pyramid. The side lengths of the base are equal.

Answers

The surface area of the triangular pyramid is the sum of the lateral surface area and the base area.

Lateral Surface Area: The lateral surface area of a triangular pyramid is equal to the product of the slant height and the perimeter of the base.

Slant height = √ ( (length of side)2 + (height)2 )

Perimeter of the base = 3 x length of side

Therefore, the lateral surface area = √ ( (length of side)2 + (height)2 ) x 3 x length of side

Base Area: The base area of the triangular pyramid is equal to one-half of the product of the three side lengths.

Therefore, the base area = 1/2 x (length of side) x (length of side) x (length of side)

Surface Area: The total surface area of the triangular pyramid = lateral surface area + base area

Therefore, the surface area = √ ( (length of side)2 + (height)2 ) x 3 x length of side + 1/2 x (length of side) x (length of side) x (length of side)

It is November 1 of Year 1. Sales for Dee Company for November and December of Year 1 and January of Year 2 are forecasted to be as follows:

November, 400,000; December 600,000; January, 200,000

60% of sales are credit sales; the remaining sales are cash sales. Of these credit sales, 5% are collected during the month of sale, 25% in the following month, and 65% in the second following month; 5% are never collected. Total sales for September and October of Year 1 were 100,000 and 150,000, respectively.

What is the forecasted amount of total cash collections in November of Year 1?

Answers

Answer:

Step-by-step explanation:

To find the forecasted amount of total cash collections in November of Year 1, we first need to determine the credit sales for September, October, November, and December of Year 1, and January of Year 2.

Credit sales for September and October of Year 1 have already been given as 100,000 and 150,000, respectively.

For November, credit sales are 60% of 400,000 = 240,000.

For December, credit sales are 60% of 600,000 = 360,000.

For January of Year 2, credit sales are 60% of 200,000 = 120,000.

Now, we need to calculate the amount of credit sales that will be collected in November of Year 1.

5% of credit sales for November will be collected in November itself, which is 5% of 240,000 = 12,000.

25% of credit sales for November will be collected in December, which is 25% of 240,000 = 60,000.

65% of credit sales for November will be collected in January of Year 2, which is 65% of 240,000 = 156,000.

The remaining 5% of credit sales for November, which is 5% of 240,000 = 12,000, will never be collected.

Therefore, the total cash collections in November of Year 1 will be the sum of cash sales for November, and the amount of credit sales collected in November:

Cash sales for November = 40% of 400,000 = 160,000

Indeed, the intermediate value theorem demonstrates that the equation   [tex]x + sin(x) = -1[/tex] must have at least one solution on the interval [-/2, /4]. Thus option B is correct.

What is the intermediate valve theorem?

The intermediate value theorem states that if a continuous function exhibits values with opposite signs at two places, there must be at least one location in the interval where it equals zero (or crosses the x-axis).

Note that x + sin(x) is a continuous function to see why. When x + sin(x) is evaluated at the interval's left endpoint, x = -/2, the result is  [tex]-/2 + sin(-/2) = -/2 - 1[/tex] , which is less than -1.

The intermediate value theorem states that because x + sin(x) is continuous and can have values both less than and greater than -1 at either end of the range, it must also have a value of -1 somewhere in between.

Therefore, When x + sin(x) is evaluated at the interval's right endpoint, x = /4, the result is  [tex]x + sin(x) = x + 2/2,[/tex]  Which is greater than -1.

Answer:

Difference=£2.4

Step-by-step explanation:

Here in shop A

130 cm=£1.82

1 cm=£1.82/130

1 cm=0.014

Now

400 cm=0.014*400

=£5.6

Again, In shop B

235cm=£1.88

1 cm=£1.88/235

1 cm=£0.008

Estimate a 15% tip on a dinner bill of $58.12 by first rounding the bill amount to the nearest ten dollars.

Answers

Answer: an estimated 15% tip on a dinner bill of $58.12 would be $8.72.

Step-by-step explanation:

First, we can calculate 10% of $58.12 by moving the decimal point one place to the left, which gives us $5.81.

Then, we can calculate half of 10%, which is 5%, by dividing $5.81 by 2, giving us $2.91.

Finally, we add 10% and 5% to get the estimated tip amount:

$5.81 + $2.91 = $8.72

Therefore, an estimated 15% tip on a dinner bill of $58.12 would be $8.72.

A system of equations is shown below.y=4xy=x-6 what is the x-value in the solution to the system? Which of these should not be included in a summary of this article?A.Experts suspect that listening to loud music on earbuds is causing the rise in hearing loss.B.A study found that 19.5 percent of teens tested between 2005 and 2006 had hearing loss.C.Some of Matthew Brady's favorites groups are Daughtry, Bon Jovi, and U2.D.The percentage of teens with hearing loss has increased since about 1990. BOSTON, Massachusetts. A recent study revealed that one in fiveMost of the hearing loss in the teens was "slight." Researchers defined "slight" as an inability to hear at 16 to 24 decibels. A teen with slight hearing loss might not be able to hear sounds such as leaves rustling or someone whispering. Dr. Gary Curhan was the study's senior author.According to Curhan, people with slight hearing loss can hear vowel sounds clearly. However, they might miss sounds from some consonants, such as t, k, and s. Experts warn that this minor loss of hearing is sufficient to cause problems in school. It also sets the stage for hearing aids later in life."Although speech will be detectable, it might not be fully intelligible," Curhan said. Researchers lack final evidence that listening to iPods and other music devices is to blame for hearing loss in teens. However, researchers did note a significant increase in high-frequency hearing loss.This particular type of hearing loss, researchers said, indicates that noise may be to blame. Researchers cited a 2010 Australian study. The study linked the use of personal listening devices with a 70 percent increased risk of hearing loss in young people"I think the evidence is out there that prolonged exposure to loud noise is likely to be harmful to hearing, but that doesn't mean kids can't listen to MP3 players," Curhan said. "Our hope is we can encourage people to be careful."Loud music isn't anything new, of course. Each recent generation of teens has found a new technology to blast music. Teens listened to bulky headphones in the 1960s and used the handheld Sony Walkmans in the 1980s. Today's teens, however, spend more time than ever listening to music. In fact, according to audiologist Brian Fligor, young people spend more than twice as much time listening to music than previous generationOne of Fligor's patients is 17-year-old Matthew Brady of Foxborough, Massachusetts. Matthew has a mild hearing loss. He has trouble hearing his friends in the school cafeteria. He has admitted to occasionally faking comprehension. Matthew used to listen to an iPod turned up too loud and for too long. Fligor believes this caused Matthew's muffled hearing.Matthew used to crank up the volume on his favoritesDaughtry, Bon Jovi, and U2while walking on a treadmill. He did this at least four days a week for 30-minute stretches at a time. One day last summer, he got off the treadmill and couldn't hear anything with his left ear. His hearing gradually returned, but it was never the same.Matthew's fondness for listening to loud music in not uncommon. During a study of college students, Fligor found that more than half of those tested listened to music at 85 decibels or louder. That's about as loud as a hair dryer or a vacuum cleaner. According to Fligor, regular listening at those levels can turn microscopic hair cells in the inner ear into scar tissue. Fligor believes that some people, such as Matthew, may be more likely to experience damage than others.These days, Matthew still listens to his digital music player. But now he listens at lower volumes."Do not [blast] your iPod," Matthew cautions other teens. "It's only going to hurt your hearing. I learned this the hard way."
