Among the most famous of all meteor showers are the Perseids, which occur each year in early August. In some areas the frequency of visible Perseids can be as high as 40 per hour. What is the probability that an observer who has just seen a meteor will have to wait at least 5 minutes before seen another.

Answers

Answer 1

Answer:

the required probability is 0.0357

Step-by-step explanation:

Given the data in the question;

X-Exp( λ = 40/60 = 0.6667

Pdf: f( x ) = λe^(-λx), 0 < x

so

Cdf: P( X < x ) = 1 - e^(-λe)

( X ≤ x ) = 1 - e^(-λe), for x > 0 ⇒ p( X > x ) = e^(-λe)

now to wait at least 5 minutes before seen another

p(X  > 5 ) = e^(-λe)

we substitute

p(X  > 5 ) = e^(-0.6667 × 5)

p(X  > 5 ) = e^(-3.3335)

p(X  > 5 ) = 0.035668 ≈ 0.0357

Therefore,  the required probability is 0.0357

the daily info newspaper charges a fee of $650 plus $80 per week to run an ad. the peoples paper charges $145 per week. for how many weeks will the total cost at the peoples paper be less expensive

Answers

The total cost at the peoples paper be less expensive will represent by the inequality 650 + 80w <  145w.

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given that the daily info newspaper charges a fee of $650 plus $80 per week to run an ad.

Assume that after w weeks the total cost at the peoples paper be less expensive.

To run ad. for w week, the cost will be 80w.

The total cost of material of newspaper is p(w) = 650 + 80w

The peoples paper charges $145 per week.

The peoples paper charges after w week will be f(w) = 145w.

According to the question:

p(w) < f(w)

how can you divide polynomials

Answers

Polynomials can be divided using long division method and

synthetic division method.

What is a polynomial?

Algebraic expressions which are made up of coefficients and variables are called polynomials.

For example x + 3, 3y² -10, r³, t³ + 4t³ - 80, etc.

Polynomials can be classified as monomials, binomials and trinomials based upon the number of terms present.

According to the given question:

There are two methods that can be employed while dividing two given polynomials:

1. Long Division Method

The long division method is the most frequent and general method for dividing polynomials by binomials or any other form of polynomials.

Steps:

Step 1: Divide the dividend’s first term by the divisor’s first term, and use it as the quotient’s first term.

Step 2: Multiply the divisor, then place the product beneath the dividend

Step 3: To make a new polynomial, subtract.

Step 4: Use the new polynomial obtained after subtraction to repeat the operation.

2. Synthetic Division Method

It is a technique for dividing a polynomial by a linear binomial using only the coefficient values. We write the polynomials in standard form from the greatest degree term to the lowest degree term in this manner.

Steps:

Step 1: Ensure that the divisor is in the form of x − k.

Step 2: Write the dividend coefficients on the right and k on the left to set up the division.

Step 3: Now, reduce the coefficient of the dividend’s highest degree term to zero.

Step 4: Multiply k by that leading coefficient and write the product below the second coefficient on the dividend’s left side.

Step 5: Multiply the numbers in the second column.

Step 6: Multiply k by the number obtained in step 5 and write the result in the next column to the right.

Step 7: Finally, we’ll write the final solution, which will be one degree below the dividend.

the difference between the measure of two supplementary angles is 92. find the measure of both angles.

Answers

The measure of both angles on calculation is found to be 44° and 136° respectively.

What are supplementary angles ?

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.

Given : difference between the measure of two supplementary angles is 92 .

Let the two angles be x and y then , x - y = 92

Since , supplementary angles add up to 180 degrees

x + y = 180 (say 1)

x - y = 92(say 2)

---------------add(1 & 2)

2x = 272

x = 272/2

x = 136 <=== this is one angle

x + y = 180

136 + y = 180

y = 180 - 136

y = 44 <=== this is the other angle

Hence , the measure of both angles on calculation is found to be 44° and 136° respectively.

In ΔVWX, x = 77 cm, ∠X=74° and ∠V=16°. Find the length of w, to the nearest 10th of a centimeter.

Answers

Answer:

The length of w is 50.0 cm.

Step-by-step explanation:

To find the length of w, we can use the Law of Sines:

w / sin V = x / sin X

Plugging in the values given in the question, we get:

w / sin 16° = 77 cm / sin 74°

Solving for w, we get:

w = 50.0 cm

Rounding to the nearest 10th of a centimeter, we get:

w = 50.0 cm

Therefore, the length of w is 50.0 cm.

Answer:

w=80.1 cm

Step-by-step explanation:

According to the Law of Sines:

[tex]\frac{\sin(\alpha)}{a}=\frac{\sin(\beta)}{b}=\frac{\sin(C)}{c}[/tex]

For this problem, let

[tex]\alpha[/tex]=∠X=74°

[tex]\beta[/tex]=∠V=16°

Since the sum of the angle measures in all triangles must equal 180°, ∠w must equal 90°.  So, for this problem, let

C=∠W=90°.

And let

a=x=77 cm

c=w

So,

[tex]\frac{\sin(74)}{77\ cm}=\frac{\sin(90)}{w}\\0.01248\ cm=\frac{1}{w}\\w=80.1\ cm[/tex]

This can be checked using the Law of Sines with all values entered.

To find b, use the Pythagorean Theorem:

[tex](80.1\ cm)^2=(77\ cm)^2+b^2\\6416.01\ cm^2=5929\ cm^2+b^2\\487.01\ cm^2=b^2\\b=22.07\ cm[/tex]

So,

[tex]\frac{\sin(74)}{77\ cm}=\frac{\sin(16)}{22.07\ cm}=\frac{\sin(90)}{80.1\ cm}\\0.0125\ cm=0.0125\ cm=0.0125\ cm[/tex]

Dr. Sparrow is a social psychologist who studies romantic relationships. Several researchers have found that there is a link between income and marital satisfaction (e.g., Dakin & Wampler, 2008). Dr. Sparrow is curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of marital satisfaction. He is confident that he cannot reasonably or ethically manipulate people's income level, so he decides to use a multivariate design. He is also curious as to whether there is a causal link between these two variables or if two other variables (number of arguments and life satisfaction) can explain the relationship.

Given Dr. Sparrow's design, his study is best able to overcome the issue of causality, as well as the issue of some potential third variables.

By using a multivariate design, Dr. Sparrow is able to examine the relationships between multiple variables simultaneously, which can help to identify the potential influence of each variable on the outcome of interest (marital satisfaction in this case). This can help to establish a causal link between the variables if one is present, as it allows for the examination of multiple variables at the same time, rather than just two variables as in a simple bivariate design.

Additionally, by controlling for other potential confounding variables, Dr. Sparrow is able to account for the potential influence of these variables on the relationship between income and marital satisfaction, which helps to establish a more robust understanding of the potential causal link between these two variables.

The interest charged on the loan was 7.5% APR compounded annually. He repaid the loan and interest in equal monthly installment for over a period of two years. Calculate the loan he made and the total amount to be repaid.

Answers

a) The loan that Neil made for the purchase of a new refrigerator is P33,030.

b) The total amount to be repaid over a period of two years is P35,672.16.

What is the loan amount?

The loan amount is the difference between the purchase price of a new refrigerator and the deposit (down payment).

The total amount to be repaid over the loan period includes the loan amount and the interest.

These amounts can be computed using an online finance calculator, including the monthly payments.

The cost of a new refrigerator = P36,700

Deposit (down payment) = 10%

The amount of the loan = P33,030 (P36,700 - P3,670)

N (# of periods) = 24 months (2 years x 12)

I/Y (Interest per year) = 7.5%

PV (Present Value) = P33,030

FV (Future Value) = P0

Results:

PMT = P1,486.34

Sum of all periodic payments = P35,672.16 ($1,486.34 x 24)

Why is it a rectangle?

To determine the special quadrilateral that is formed by connecting the midpoints of the sides of the quadrilateral with vertices (2,0), (0,-2), (-2,4) and (-4,2), we can find the midpoints of each side and then determine the shape formed by these points.

The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. To find the midpoint of a line segment, we can take the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.

We can find the midpoint of the side between (2,0) and (0,-2) by taking the average of the x-coordinates (2 and 0) and the average of the y-coordinates (0 and -2), which gives us the point (1,-1).

We can find the midpoint of the side between (0,-2) and (-2,4) by taking the average of the x-coordinates (0 and -2) and the average of the y-coordinates (-2 and 4), which gives us the point (-1,1).

We can find the midpoint of the side between (-2,4) and (-4,2) by taking the average of the x-coordinates (-2 and -4) and the average of the y-coordinates (4 and 2), which gives us the point (-3,3).

We can find the midpoint of the side between (-4,2) and (2,0) by taking the average of the x-coordinates (-4 and 2) and the average of the y-coordinates (2 and 0), which gives us the point (-1,1).

Help!!! It doesn’t give the isosceles congruent angles??

Answers

Answer: y = 11 , x =3

Step-by-step explanation:

Since its an isosceles triangle , two angles or two side are equal.

So lets take 5y - 3 as one of the equal angles, so

5y-3+ 5y-3 + 76 = 180 (angles in a triangles should add up to 180)

10y - 6 + 76 = 180

10y = 180 - 70

10y =110

y = 110/10

y = 11

Now, since we found y we need to find x.

Lets us take 8x and 13x - 15 as the equal sides.

8x = 13x - 15

8x - 13x = -15

-5x = -15

x = -15 / -5

x = 3

so we found the values of x and y !

Answer:

x = 3y = 11

Step-by-step explanation:

You want the values of x and y, given an isosceles triangle with congruent sides JK=8x and KL=13x-15, angle K=76°, and angle J=(5y-3)°.

Congruent sides

  JK = KL

  8x = 13x -15

  15 = 5x . . . . . . add 15-8x

  3 = x . . . . . divide by 5

Sum of angles

The sum of the angles in the triangle is 180°.

  2(∠J) +∠K = 180°

  2(5y -3) +76 = 180 . . . . substitute known values, divide by °

  10y +70 = 180 . . . . . . simplify

  y +7 = 18 . . . . . . . . divide by 10

  y = 11 . . . . . . . . . subtract 7

The values of x and y are 3 and 11, respectively.

f ( x ) = ( x − 2 ) ( x + 4 ) ( x + 5 ) ( x − 1 ) ( x − 9 ) has zeros at x = -5, x = -4, x = 1, x = 2, x = 9

What is the sign of F on the interval -4 < x < 1?

Answers

The sign of F on the interval -4<x<1 is 0

How to do substitution in a function?

We know that in mathematics,  a function from a set X to a set Y assigns to each element of X exactly one element of Y.

The given function is

f(x)=(x-2)(x+4)(x+5)(x-1)(x-9)

The Interval is given as -4<x<1

Substituting the values of x in the function we have

f(x)=(-5-2)(-4+4)(1+5)(2-1)(9-9)

This implies that

f(x)=(0)(0)(6)(1)(0)

Multiplying the brackets to have

f(x)=0

In conclusion, the sign of F on the interval -4<x<1 is 0
