Use cylindrical coordinates. Evaluate x2 + y2 dV, E where E is the region that lies inside the cylinder x2 + y2 = 9 and between the planes z = −2 and z = 5.

Answers

Answer 1

 The region that lies inside the cylinder between the planes z = −2 and

z = 5 is 324π

Using cylindrical coordinates,

the integral becomes

∫∫∫ (r2) drdθdz, E

where E is the region that lies inside the cylinder r2 = 9 and between the planes z = −2 and z = 5.

The integral can be evaluated as follows:

=  ∫₋₂⁵∫₀²π∫₀³ [tex]r^2[/tex]drdθdz

= ∫₋₂⁵∫₀²π(3[tex]r^3[/tex]/3) dθdz

=  ∫₋₂⁵ (2π × (3 × 93/3)) dz

=  ∫₋₂⁵ (108π) dz

= (108π × (5 − (−2)))

= 324π

A basketball player has a constant probability of 0.4 of making any given shot, independent of previous shots. Let an be the ratio of shots made to shots attempted after n shots. The probability that a10 = 0.4 and an ≤ 0.4 for all n such that 1 ≤ n ≤ 9 is given to be p^aq^br/s^c where p,q,r and s are primes, and a, b, and c are positive integers. Find (p+q+r+s)(a+b+c)

Answers

The value of (p+q+r+s) / (a+b+c) is 3.66 if the basketball player has probability 0.4 to make a perfect shot.

We know that if probability is given for r distribution and if question is asking distribution for n terms, we need to use binomial probability distribution which is given by [tex]^nC_r[/tex][tex]p^r[/tex][tex]q^r[/tex] where p is defined as the success probability and q is called as failure probability.

We have success probability =0.4

Failure probability(q) = 1-p=1-0.4=0.6

From 9 terms, we need to choose single term having success probability =0.4 and failure probability=0.6

So, this can be given by =[tex]^9C_1[/tex] × (0.4)¹ ×(0.6)⁹⁻¹

which is equivalent to =9 × (0.4) × (0.6)⁸

On comparing with the given equation =([tex]p^a[/tex] × [tex]q^b[/tex]×[tex]r^d[/tex]) / [tex]s^c[/tex] ,we get

p=9,a=1,q=0.4,b=1,r=0.6,d=8,s=1,c=1.

So,value of p+q+r+s = 9+0.4+0.6+1=11

and value of a + b + c = 1+1+1=3

So, value of (p + q + r + s) / (a + b + c)= 11 / 3=3.66

Hence, required value is 3.66

Answers

The error in computing the area of triangle is 10.75 and the percentage error in computing the area of triangle is 1.194%.

Given that, base of the triangle is 36 cm (a)

Altitude of the triangle is 50 cm (b)

Error in each measurement is 0.25 cm

We know that, area of the triangle (s) = 1/2 * base * altitude

Let us consider base as ' a ' and altitude as ' b '

So, the maximum error of ' s ' can be calculated as

⇒ ds/da * da + ds/db * db

⇒ 1/2* b * da + 1/2 *a * db

⇒ 1/2* 36 * 0.25 + 1/2* 50* 0.25

⇒ 4.5 + 6.25 = 10.75

Now, let us calculate the percentage error in computing the area of the triangle.

dA/A * 100 = [(1/2* b* da + 1/2* a * db)/ 1/2* b *h] * 100

⇒ [(1/2* 36 * 0.25 + 1/2* 50 * 0.25)/ 1/2* 36 * 50] * 100

⇒ [ 21.5/ 1800 ] * 100

⇒ 1.194%

Thus, the error in computing the area of the triangle is 10.75 and the percentage error in computing the area of the triangle is 1.194%.

sin(theta) * sec(theta) - 2sin(theta) = 0

Solve with all possible answers for theta

Answers

Answer:

θ = 2 π n_1 + π/3 for n_1 element Z

or θ = 2 π n_2 + (5 π)/3 for n_2 element Z

or θ = π n_3 for n_3 element Z

θ = π n_3 for θ element Z and cos(θ)!=0 and n_3 element Z

Step-by-step explanation:

Solve for θ:

tan(θ) - 2 sin(θ) = 0

Factor sin(θ) from the left hand side:

sin(θ) (sec(θ) - 2) = 0

Split sin(θ) (sec(θ) - 2) into separate parts with additional assumptions.

Assume cos(θ)!=0 from sec(θ):

sec(θ) - 2 = 0 or sin(θ) = 0 for cos(θ)!=0

Add 2 to both sides:

sec(θ) = 2 or sin(θ) = 0 for cos(θ)!=0

Take the reciprocal of both sides:

cos(θ) = 1/2 or sin(θ) = 0 for cos(θ)!=0

Take the inverse cosine of both sides:

θ = 2 π n_1 + π/3 for n_1 element Z or θ = 2 π n_2 + (5 π)/3 for n_2 element Z

or sin(θ) = 0 for cos(θ)!=0

Take the inverse sine of both sides:

θ = 2 π n_1 + π/3 for n_1 element Z

or θ = 2 π n_2 + (5 π)/3 for n_2 element Z

or θ = π n_3 for cos(θ)!=0 and n_3 element Z

The roots θ = π n_3 never violate cos(θ)!=0, which means this assumption can be omitted:

Answer: θ = 2 π n_1 + π/3 for n_1 element Z

or θ = 2 π n_2 + (5 π)/3 for n_2 element Z

or θ = π n_3 for n_3 element Z

Solve for θ over the integers:

tan(θ) - 2 sin(θ) = 0

Factor sin(θ) from the left-hand side:

sin(θ) (sec(θ) - 2) = 0

Split sin(θ) (sec(θ) - 2) into separate parts with additional assumptions.

Assume cos(θ)!=0 from sec(θ):

sec(θ) - 2 = 0 or sin(θ) = 0 for cos(θ)!=0

Add 2 to both sides:

sec(θ) = 2 or sin(θ) = 0 for cos(θ)!=0

Take the reciprocal of both sides:

cos(θ) = 1/2 or sin(θ) = 0 for cos(θ)!=0

Take the inverse cosine of both sides:

θ = 2 π n_1 + π/3 for θ element Z and n_1 element Z or θ = 2 π n_2 + (5 π)/3 for θ element Z and n_2 element Z

or sin(θ) = 0 for cos(θ)!=0

The roots θ = 2 π n_1 + π/3 violate θ element Z for all n_1 element Z:

θ = 2 π n_2 + (5 π)/3 for θ element Z and n_2 element Z

or sin(θ) = 0 for cos(θ)!=0

What is a p- value or chi square test?

A chi square ( χ2) test is performed in order to find a co relation between two unrelated variables. The main objective of the test is to prove whether the relationship holds true or is just a product of mere chance. For example, if we are conducting a survey of two different paramters, first being the population of people who are married and the other about their educational qualififcation, we will get two distinct table of values without any significant corelation. But now if we wnt to establish a relationship, lets say that married people have less educational qualifications, we need to prove our statement by performing a chi square test. The final value can either be a null hypothesis which states that their is no convinving relationship betwwen the two paramters or can be a alternate hypothesis with significant corelation.

How de we tackle this specific problem with the test?

For this problem lets focus on the male fish population alone and perform the test:

                                                       Population (Observed)

                              A                      B                    C                 D           TOT

Male fish                49                   44                   49               39           181

Female fish            41                    46                   36               44           167

                              90                   90                   85               83           348

                                                        Population(Expected)

Male fish                 46.81              46.81               44.20           43.16

Female fish              43.18             43.18               40.79           39.83

χ2 = ∑[tex]\frac{(Obsereved-Expected)^2}{Expected}[/tex];

=[tex]\frac{4.79}{46.81} +\frac{7.89}{46.81} +\frac{23.04}{44.20} +\frac{17.30}{43.16}[/tex]

= 0.10+0.16+0.52+0.40 = 1.18

Now to calculate degree of freedom= (coulmn-1)(row-1)= 3×1= 3.

Looking at the reference table at 0.05 significance level, the value shows 7.815

Thus as our value of 1.18 is less than the given value, null hypothesis cannot be rejected.

Hence the population proportions are not equal at all four locations. Whether this conclusive difference in gender proportions is due to varied contaminants cant be answered with this single observation and further tests are needed to be performed to construct a well found connection.

Here we have

Martina, Ahmad, and Ryan served a total of 87 orders

Since we don't how many orders served each one

Let's assume that each of them with different variables

Martina served 'm' orders

Ahmad served 'a' orders

Ryan served 'r'

Given that

Ahmad served 9 fewer orders than Martina  

=> a = m - 9 ---- (1)

Ryan served 2 times as many orders as Martina.

=> r = 2m --- (1)    

Given that total served orders = 87

=> m + a + r = 87

=> m + m - 9  + 2m = 87        [ from (1) and (2) ]

=> 4m = 87 + 9

=> 4m = 96

=> m = 24

Number of orders served by Ahmad, a = 24 - 9 = 15  

Number of orders served by Ryan, r = 2(24) = 48

A 6 inch personal pizza has 610 calories, with 240 of those from fat. A 12 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 12 inch pizza.
A circle's area goes up with the square of its radius (A = πr2). Since the 12-inch pizza has twice the radius of the six-inch pizza it has 22 = 4 times the area. In addition, since the 12-inch pizza is then cut into 8 slices, each slice has 4/8 = 1/2 times the area of the 6-inch pizza, so each slice has approximately 1/2*610 = 305 calories.

Answers

If the 12 inch pizza is cut into 8 (equal) slices, the number of calories in one slice is 2440/8 = 305.

"Information available from the question"

In the question:

A 6 inch personal pizza has 610 calories, with 240 of those from fat. A 12 inch pizza is cut into 8 slices.

Estimate the number of calories in one slice of a 12 inch pizza.

Now, According to the question:

The 6 inches and 12 inches are  the diameters of the two pizzas.

Consider the two pizzas as similar figures with a ratio of similarity of 2:1. By a basic geometric principle, the ratio of the areas of the two pizzas is the square of that ratio. So the area of the 12 inch pizza is 2^2=4 times the area of the 6 inch pizza.

The number of calories in the 6 inch pizza is 610.

The number of calories in the 12 inch pizza is 610 x 4  = 2440.

Hence, If the 12 inch pizza is cut into 8 (equal) slices, the number of calories in one slice is 2440/8 = 305.

Likewise, let's let y = the number of hours working at the pizza place. Her total pay there would be 9.25y.

Her all together over all pay would be:

bookstore$ + pizza$

8.25x + 9.25y

= 247

8.25x + 9.25y = 247

here is one equation. It tells us her total pay from both jobs is 247.

Also, her hours totaled 28. So,

x + y = 28

Solve the system of equations:

8.25x + 9.25y = 247

x + y = 28

You could use substitution or elimination. If you are learning matrices or a graphing program you could use that.

Here is the substitution work.

x + y = 28

y = 28 - x

8.25x + 9.25y = 247

substitute. y = 28-x

8.25x+9.25(28-x)=247

use distributive property.

8.25x+259 - 9.25x=247

combine like terms.

259 - x = 247

subtract 247, add x

12 = x

This means that Rosemary worked 12 hours at the bookstore. And since 28 - 12 = 16.

She works 16 hours at the pizza delivery

12 + 16 is 28, the number of hours she worked.

Also, 8.25(12)+9.25(16)

= 99 + 148

= 247

So these number check out.

Suppose Y is a dichotomous dependent variable, and the data-generating process for Y can be expressed as: Yi=0.1+0.03X1i−0.02X2i+Ui, Interpret the coefficients on X1 and X2

Answers

The coefficient of x1 = 0.03 and the coefficient of  x2 = - 0.02.

The coefficient of x1 is  positive we can say there is a positive relationship  between x1 and y as the x1  value increases, the y value also increases

If the x1 value increases as 1 unit then the y  value increases as 0.03 unit while x2 keeps constant.

The coefficient of x2 is negative we can say there is a negative relationship between x2 and y as the x2 value increases y  value decreases.

If the x2 value increases as 1 unit then the y value decreases as 0.02 unit while x1 keeps constant.

A dichotomous variable is one that takes on one of just two potential qualities when noticed or estimated. The worth is most frequently a portrayal of a deliberate variable (e.g., mature: under 65/65 and over) or a quality (e.g., orientation: male/female).

The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

the spearman correlation coefficient differs from the pearson correlation coefficient in that only the spearman correlation coefficient makes use of significance testing

Answers

The Spearman correlation coefficient is used to calculate a significance test, whereas the Pearson correlation coefficient is not.

The Spearman correlation coefficient is a non-parametric measure of correlation that uses ranks rather than raw data to assess the strength of the relationship between two variables. This makes it more robust than the Pearson correlation coefficient, which relies on the assumption that the two variables have a normal distribution. Additionally, Spearman correlation coefficients are used to measure the degree of monotonicity between two variables, while Pearson correlation coefficients are not. Finally, the Spearman correlation coefficient is used to calculate a significance test, whereas the Pearson correlation coefficient is not.
