Step-by-step explanation:

well because it says =20 and the bottom one has a 6 and so does the space the that means 3+20+23

The value of the integral is ln(1/6) + (3/2) ln(3). To evaluate the integral S18 1 (√3/z)dz, we can use the substitution u = √3/z, which implies du/dz = (-√3/z²) and dz = (-z²/√3) du.

Substituting u = √3/z and dz = (-z²/√3) du, the integral becomes:

S18 1 (√3/z)dz = -S√3/18 ∞ √3/1 u du

= -S√3/18 ∞ √3/1 (√3/u) du

= -S1 18 (3/u) du

= -3ln(u) |1 18

= -3ln(18/√3) + 3ln(1/√3)

= -3ln(6) + 3ln(√3)

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

= ln(1/6) + (3/2) ln(3)

Therefore, the value of the integral is ln(1/6) + (3/2) ln(3).

Answer:

  y = kx . . . . . k is the constant of proportionality

where k = 7.6.

The constant of proportionality is 7.6.

The probability that a student learns more than 11 years is approximately 0.0548 or 5.48%

To find the probability that a student learns more than 11 years, we need to calculate the area under the normal distribution curve to the right of 11.

Given that the mean of the distribution is 7 years and the standard deviation is 2.5 years, we can standardize the value of 11 using the formula:

z = (x - μ)/σ

= (11 - 7)/2.5

= 1.6

We can then use a standard normal distribution table or calculator to find the probability that a standard normal random variable is greater than 1.6. Using a calculator, we get:

P(Z>1.6) = 0.0548

Therefore, the probability that a student learns more than 11 years is approximately 0.0548 or 5.48%

The option that is not a valid point of comparison between histograms and graphs is: C. Histograms represent quantitative data, while bar graphs represent qualitative data.

Histograms are a way of displaying data in a graph that gives an idea of the frequency distribution of that data.

It is a graphical representation of numerical data that is divided into segments or bins.

They are a sort of bar graph where the bars represent the frequency distribution of the data.

How do histograms work?

Histograms represent the frequency distribution of data in a visual format.

It is done by dividing the data into segments and plotting their frequency distribution using vertical bars.

The bars' height is proportional to the number of data points that fall within that range, while the bars' width represents the range of values the data encompasses.

Additionally, the bars in histograms touch since they represent a continuous range of values, whereas in bar graphs, they don't have to.

Answer:

P(A n B) = 1/4

Step-by-step explanation:

We know that:

P(A U B) = P(A) + P(B) - P(A n B)

Substituting the given values, we get:

3/8 = 1/2 + 3/4 - P(A n B)

Simplifying, we get:

P(A n B) = 1/4

Answer: P ( A n B ) = 7/8

Step-by-step explanation:  P ( A U B ) = P(A) + P(B) - P( A n B )

                                                         3/8   =   1/2  + 3/4 - P( A n B )

                                                         3/8   =   5/4 - P ( A n B )

Step-by-step explanation:

The percent increase from 200 to 460 is 130% increase

The numbers are given as

200 and 460.

460 is greater than 200

So, the percentage is an increment

The percentage increment is then calculated as

Percentage = (Final value - Initial value)/Initial value * 100%

Substitute the known values in the above equation

Percentage = (460 - 200)/200 * 100%

Evaluate the difference

So, we have

Percentage = 260/200 * 100%

Evaluate the quotient

So, we have

Percentage = 1.3 * 100%

Evaluate the product

So, we have

Percentage = 130%

Hence, the percent increase from 200 to 460 is 130% increase

Using the elimination method, the price of one t-shirt is $30 and one key-chain is $11.

In the given question, Elizabeth's family went to NYC for their vacation.

At the gift shop on Liberty Island, Valerie bought three t-shirts and four key chains for $134, and Jennifer bought four t-shirts and five key chains for $175.

We have to find the price of each item.

Let the price of one t-shirt = $x

Let the price of one Key chain = $y

According to question

Price of three t-shirts and four key chains = $134

So the equation is

3x + 4y = $134……………….(1)

Also,

Price of four-shirts and five Key chains = $175

So the equation is

4x+5y = $175……………………..(2)

Now solving the equation using the elimination method.

Multiply Equation (1) by 5 and Equation (2) by 4, we get

15x+20y = 670....................(3)

16x+20y = 700......................(4)

Subtract equation 4 and 3, we get

x = 30

Now put the value of x in equation 1,

3*30 + 4y = $134

90+4y=$134

Subtract 90 on both side, we get;

4y = 44

Divide by 4 on both side, we get;

y = 11

Hence, the price of one t-shirt is $30 and one key-chain is $11.

Answer:

Step-by-step explanation:

The altitude of the airplane after 6 minutes is 15900 feet

The altitude of the airplane at the beginning = 28500 feet

The distance that they descend per minutes = 2100 feet

The distance that airplane descend after 6 minutes = The distance that they descend per minutes × 6

Substitute the values in the equation

The distance that airplane descend after 6 minutes = 2100 × 6

= 12600 feet

The airplane's altitude after 6 minutes = The height of the airplane at the beginning - The distance that airplane descend after 6 minutes

= 28500 - 12600

= 15900 feet

Hence, the altitude of the airplane after 6 minutes is 15900 feet

The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.

Then time taken for the first trip will be

t₁ = 867 / 612

t₁ = 1.4167 hours

Then time taken for the second trip will be

t₂ = 1984 / 744

t₂ = 2.6667 hours

Then the average speed is the ratio of the total distance to the total time.

The total distance will be

Total distance = 867 + 1984

Total distance = 2851 miles

The total time will be

Total distance = 1.4167 + 2.6667

Total distance = 4.0834 hours

Then the average speed will be

Average speed = 2851 / 4.0834

Average speed = 698.19 mi/h

In an isosceles trapezoid, two pairs of adjacent angles are supplementary. It means that the sum of the adjacent angles is 180°

Looking at the diagram, angle X and angle W are adjacent angles. It means that

X + W = 180

Since X = 105, then

105 + W = 180

W = 180 - 105 = 75°

Since W = b + 25°, then

b + 25° = 75

b = 75 - 25 = 50°
