The dimensions are in centimetres.
The volume of the cone is 22500 cm³.
Work out the value of p

How do i work this out?

The p - value of the given hypothesis is P(2<x<6.75) is 0.49974

How to calculate p - value?

In statistics,  p-value is calculated using integral calculus from the area under the probability distribution curve for all values of statistics that are at least as far from the reference value as the observed value is, relative to the total area under the probability distribution curve.

Here we have given that an article in neurology (1998, vol. 50, pp. 1246-1252) discussed that monozygotic twins share numerous physical, psychological, and pathological traits. the investigators measured an intelligence score of 10 pairs of twins, and the data.

And we need to find the value of p from it.

Here we have the following sample data,

=>2,5.73,5.80,6.08,6.22,7.99,7.44,6.48,7.99,6.32,7.60,6.03,7.52,8.42,6.84,6.43,8.76,6.32,7.62,6.59,7.67

Through the sample data we ahve identified the following values,

Standard Deviation, σ: 1.3737491940207

Count, N: 21

Sum, Σx: 141.85

Mean, μ: 6.7547619047619

Variance, σ2:  1.8871868480726

in order to find the p-value, we have to calculate the z score for the given data,

Z score = (x - μ)/σ

=> (2 - 6.75)/ 1.37

=> -3.46715

P-value from Z-Table:

=> P(x<2) = 0.000263

=> P(x>2) = 1 - P(x<2) = 0.99974

=> P(2<x<6.75) = 0.5 - P(x<2) = 0.49974

Answer:

  A, B, C

Step-by-step explanation:

You want to find the dimensions, perimeter, and area of a foundation such that the length is 6 feet more than twice the width, and the area is 1046 more that the value of the perimeter.

We can let x and y represent the length and width, respectively. Then the given relations translate to the equation ...

  A = LW . . . . . . . area formula

  P = 2(L +W) . . . . perimeter formula

  y = 2x +6 . . . . . relation between dimensions

  xy = 2(x +y) +1046 . . . . . relation between perimeter and area

Using the first equation to substitute for y, we have ...

  x(2x +6) = 2(x +(2x +6)) +1046

  2x² +6x = 6x +1058 . . . . . . . . . . . . eliminate parentheses

  x² = 529 . . . . . . . . . . . . . subtract 6x and divide by 2

  x = √529 = 23 . . . . . . . . . width; matches B

  y = 2(23) +6 = 52 . . . . length

  area = (23)(52) = 1196 . . . area; matches A

  perimeter = 2(23 +52) = 2(75) = 150 . . . . matches C

The area is 1196 square feet. (A)

The arithmetic mean of a and b in the expression  1/a + 1/b = 1/c is 2c.

Arithmetic mean or average can be obtained by adding all the given values and then dividing the total sum by the number of values.

Given, An expression of the form 1/a + 1/b = 1/c.

We know average of two numbers is sum of those numbers divided by 2.

So,  {(1/a) + (a/b)}/2 = 1/c.

Now to keep the equality we also have to divide the RHS by 2.

Therefore,   {(1/a) + (a/b)}/2 = (1/c)/2.

{(1/a) + (a/b)}/2 = (1/c)×((1/2).

{(1/a) + (a/b)}/2 = 1/2c.

So, The arithmetic mean of 1/a + 1/b is 1/2c.

Now taking the reciprocal of 1/a and 1/b which is a and b the arithmetic mean is

Step-by-step explanation:

The measure of angle 1, m∠1, found using the congruency of the angles and the angle sum property of a triangle is 55°

The angle sum property of a triangle specifies that the sum of the interior angles of a triangle is 180°

Please find attached the presentation of the details of the question as a drawing of the triangles created with MS Word

The parameters of the question are;

The number of arcs on angles b and q = Single arcs

Therefore, based on the arc markings indicating congruency of the angles, we get;

Angle b is congruent to angle q ∠b ≅ ∠q

Therefore, ∠b = ∠q, by the definition of congruency

The number of arcs on angle a and angle s = Double arcs

Therefore, angle a is congruent to angle s based on the arc markings, which indicates;

∠a ≅ ∠s
∠a = ∠s by the definition of congruency

The label on angle ∠a = 45°

The label on angle ∠b = 80°

∠a = ∠s, therefore, ∠s = 45°, by substitution property

∠b = ∠q, therefore, ∠q = 80° by substitution

∠s + ∠q + ∠1 = 180° Angle sum property of a triangle

45° + 80° + m∠1 = 180°

m∠1 = 180° - (45° + 80°) = 55°

The expressions for the total costs are 2L + 0.7L  and 2.7L

From the question, we have the following parameters that can be used in our computation:

Number of litres = 3

Regular price = L

Discount = 30%

This means that there is a discount on the third item

So, we have the following expression

Total amount = 2 * L + L * (1 - discount)

Substitute the known values in the above equation, so, we have the following representation

Total amount = 2 * L + L * (1 - 30%)

Total amount = 2 * L + L * 0.7

This gives

Total amount = 2L + 0.7L

Evaluate the sum

Total amount = 2.7L

The population we're trying to predict is the population that is going to be Voters in our area, the where should probably be well as above our area, and the how now, generally speaking, we want to do a simple, random, or a random sample of some sort, random sample.

For instance, what you could do would be something like choose: random addresses in the area and send a survey, but sending a survey could introduce self-selection bias. So it would be ideal to visit in person basically and ask a few questions making sure the representative sample or how to ensure that we're getting a representative sample would be to, for instance, filter the random results and make sure that we have an even distance.

Ensure that there's an equal number within each quadrant of the town, basically split up the town.  Split towns into regions of populations or population densities and make sure we get the same proportion from each region.  However, we end up splitting the town into different regions. We show the proportion or show who is the most popular candidate in each 1 of the regions, so it could be something like this. That was supposed to be an alternative to a bar graph. The number of results for each different candidate depends on whether or not there's a sort of well-defined districts or areas in the town, but most sorts of relatively large cities have things like that. So the idea would be to represent not just the location, but also the information that you gain separately.

Split up the town so that there are an equal amount in each of its four quadrants. Make sure we receive the same proportion from each region by dividing towns into population or population density regions. But ultimately, we divide the town into many parts. It might look something like this since we display the percentage or the candidate who is most supported in each location. That was meant to be a bar graph substitute. Whether or not a town has clearly defined districts or areas affects the amount of results for each candidate, although this is true of most types of moderately large cities.

The general indefinite integral of ([tex]e^{x}[/tex]+ 1/8x) is ∫([tex]e^{x}[/tex]+ 1/8x) dx

= [tex]e^{x}[/tex]+ 1/4x + C

An integral is considered to be indefinite if it has no upper or lower bounds.

The most generic anti-derivative of f(x) is known as an indefinite integral and denoted, in mathematics, by F(x), which is any anti-derivative of f(x).

f(x) dx = F(x) + C

The integral of [tex]e^{x}[/tex] = [tex]e^{x}[/tex]

so ∫[tex]e^{x}[/tex] dx = [tex]e^{x}[/tex] + C

The integral of 1/8x = 1/4x,

so ∫1/8x dx = 1/4x + C

To find the integral of ([tex]e^{x}[/tex] + 1/8x), add the integrals of each term:

In an arithmetic sequence, each term is obtained by adding the common difference to the previous term. In this case, the common difference is 3, so the formula for the nth term of the sequence can be written as:

a^n = a^1 + (n-1) * d

where a^1 is the first term of the sequence, and d is the common difference.

Since the first term of the sequence is -25 and the common difference is 3, we can plug these values into the formula to find the 30th term of the sequence:

a^30 = (-25) + (30-1) * 3

= (-25) + 29 * 3

= (-25) + 87

To find the total time required to produce each product, we can add up the machining, polishing, and assembling hours for each product. For example, for Product I, the total time required would be:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

We can do this for each product to find the total time required for all four products:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

Total time for Product II = 2 hours + 1 hour + 1 hour = 4 hours

Total time for Product III = 2 hours + 2 hours + 2 hours = 6 hours

Total time for Product IV = 4 hours + 3 hours + 1 hour = 8 hours

So, the total time required to produce all four products is 6 hours + 4 hours + 6 hours + 8 hours = 24 hours.

Christopher can work average 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Christopher is working two summer jobs and has a maximum of 16 hours to work in a given week. He is making $7 per hour babysitting and $10 per hour washing cars. To meet the minimum wage requirement of $130, he needs to make a total of $130 in a week. We can represent this using a system of inequalities. The first inequality is 7xx + 10yy ≥ 130, which means that the total wages (7 times the hours babysitting plus 10 times the hours washing cars) must be greater than or equal to $130. The second inequality is xx + yy ≤ 16, which means that the total hours (babysitting plus washing cars) must be less than or equal to 16. Graphically, we can solve this system of inequalities to find the possible solutions. One possible solution is x = 9 and y = 7, meaning Christopher can work 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Graphically:

7xx + 10yy ≥ 130

xx + yy ≤ 16

7xx + 10yy = 130

xx + yy = 16

Therefore, the solution is x = 9 and y = 7.

Answer:

The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, 95% lies within two standard deviations, and 99.7% lies within three standard deviations.

In this case, the mean is 100 and the standard deviation is 15, so approximately 95% of the data lies within two standard deviations of the mean. Since two standard deviations of 100 is 30 (15 * 2), this means that approximately 95% of the data lies within the range of 70 to 130. Therefore, approximately 5% of the data lies outside of this range, with 2.5% lying below 70 and 2.5% lying above 130.

Therefore, the percent of IQ scores that are above 130 is approximately 2.5%.

∠N° = 19°

∠M° = 35°

∠L° = 126°

Step-by-step explanation:

Total angle in a triangle: 180°

∠N° = x°

∠M° = ( 2x - 3 )°

∠L° = ( 7x - 7 )°

180 = N + M + L

180 = x + 2x - 3 + 7x - 7

180 = 10x - 10

10x = 180 + 10

10x = 190

Divide both side by 10

x = 19

∠N° = x° = 19°

∠M° = ( 2x - 3 )° = ( 2(19) - 3 )° = 35°

∠L° = ( 7x - 7 )° = ( 7(19) - 7 )° = 126°
