Ravi sells real estate. Based on previous data, he knows that 5% of home tours result in a sale. Assume that the results of these tours are independent from each other. Which of the following choices are binomial random variables? Choose all answers that apply: A. Take a random sample of 30 tours and let L = the number of tours that result in a sale. B. Take a random sample of 3 tours and let K = the number of tours that result in a sale. C. Take a random sample of 3 tours and let M = the amount of sales (in dollars) generated by the tours

Answers

Answer 1

The following choices are binomial random variables: A. Take a random sample of 30 tours and let L = the number of tours that result in a sale. B. Take a random sample of 3 tours and let K = the number of tours that result in a sale.

Choice A is a binomial random variable because it represents the number of tours that result in a sale in a random sample of 30 tours. The trials are independent, as the results of one tour do not affect the results of other tours, and the probability of success (a sale) is constant at 5%.

Choice B is also a binomial random variable because it represents the number of tours that result in a sale in a random sample of 3 tours. The trials are independent and the probability of success is constant at 5%.

Choice C is not a binomial random variable because it represents the number of sales generated by a random sample of 3 tours, which is a continuous variable. Binomial random variables are always discrete, as they represent the number of successes in a sequence of trials.

The principal that would need to be invested is  $4202.

What is the principal?

We know that the principal has to  do with the amount of money that you have to invest so as to be able to obtain an interest. The interest in this case is a simple interest and it is charged on the principal. The amount is the sum of the principal and the interest.

We now have;

A = I + P

A = amount

I = interest

P = principal

But I = PRT/100

R = rate

T = time

We have;

A = PRT/100 + P

5000 = P * 9.5 * 2/100 + P

5000 = 19P/100 + P

5000 = 19P + 100P/100

5000 * 100 = 119P

P = 500000/119

Great job , you’ve already earned 1300 points, it there are 5 more days in this month. How many points a day do you need to reach your goal of 1580 points?

Answers

Answer:

56 points

Step-by-step explanation:

Let's say that for the next 5 days, you earn x points each day. This means that you will earn 5x more points before the month ends.

Since you already earned 1300 points, you will have earned 1300 + 5x points, which through the question we know is equal to 1580 points. Using this knowledge, we can set up the equation below:

1300 + 5x = 1580

5x = 280

x = 56

Therefore, you will need 56 points each day to reach your goal.

Richard will increase the amount of time he studies each night from a period of 40 minutes to a period of 50 minutes. By what percentage will Richard increase the amount of time he studies each night?

Answers

Richard will increase the amount of time he studies each night by 25%.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

To find the percentage increase, we need to first find the difference between the two amounts of time.

In this case, the difference is 50 minutes - 40 minutes = 10 minutes.

Next, we need to divide the difference by the original amount of time and multiply by 100% to express the answer as a percentage.

In this case, the percentage increase is :

⇒ (10 / 40) x 100% = 25%.

Therefore, he will increase the amount of time he studies each night by 25%.

convert the given rectangular coordinates to polar coordinates

(-2, 5)

Answers

So in this question, we have to convert the rectangular coordinates to polar coordinates.

Polar coordinates are (r, Q).

To convert rectangular coordinates to polar coordinates we use that x is equal to  rcosQ and y is equal to rsinQ

In this question x is equal to -2 and y is equal to 5.

Hence we have -2 is equal to rcosQ and 5 is equal to rsinQ .

From here, we have tanQ equal to -2.5 . Hence, Q = tan⁻¹ (-2.5)

We have x²+y² =r² and also x²+y² = 5²+2²=29 .

Hence, r=√29 and Q = tan⁻¹ (-2.5) .

Therefore the polar coordinates of (-2,5) are ( √29, tan⁻¹ (-2.5)).

What is a triangle?

The three-sided shape known as a triangle is sometimes used to allude to it.

The area of a triangle is defined as (1/2) base height, and the sum of all three angles within a triangle will be 180°.

As the given triangular garden has been drawn below,

By Pythagoras' theorem,

x² + (x + 7)² = (x + 8)²

x² + x² + 49 + 14x = x² + 64 + 16x

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x(x - 5) + 3(x - 5) = 0

(x + 3)(x - 5) = 0

x = -3,5

Since length can never be negative thus x = 5.

The smallest leg = 5 feet

Biggest leg = 5 + 7 = 12 feet

Hence "The triangular garden's smallest leg is 5 feet long, while its longest leg is 12 feet".

The equation [tex]0.4^3 = 0.064[/tex] is a counterexample to the given conjecture because 0.064 is less than 0.4. This shows that the cube of a number is not always greater than the number.

In general, the cube of a number is the result of multiplying the number by itself three times. For example, the cube of 2 is [tex]2 * 2 * 2 = 8[/tex], and the cube of 5 is [tex]5 * 5 * 5 = 125[/tex]. The cube of a number is always greater than the number when the number is positive, because a positive number multiplied by itself three times is always a larger number. However, when the number is negative or a decimal, this is not always the case.

In the given equation, 0.4 is a decimal number, and [tex]0.4^3[/tex] is the cube of 0.4. The result of this calculation is 0.064, which is less than 0.4. This means that the cube of 0.4 is not greater than 0.4, and therefore the given conjecture is false.

Suppose you have the following three student loans: $12,000 with an APR of 7.5% for 17 years, $18,000 with an APR
of 8% for 22 years, and $13,500 with an APR of 9% for 12 years.
a. Calculate the monthly payment for each loan individually.
b. Calculate the total you'll pay in payments during the life of all three loans.
c. A bank offers to consolidate your three loans into a single loan with an APR of 8% and a loan term of 22 years.
What will your monthly payments be in that case? What will your total payments be over the 22 years?

Answers

a) The monthly payment for each loan individually is as follows:

                                 Loan A        Loan B         Loan C          Total

Monthly payments $133.82        $188.18      $195.00      $517.00

b) The total payments during the life of all three loans is $105,060, classified as follows:

                                 Loan A        Loan B         Loan C          Total

Total amount          $27,300     $49,680     $28,080    $105,060

c) The monthly payments after consolidating the three loans are $350.69.

d) The total payments over the 22 years period will be $92,581.47.

How are the monthly payments determined?

Note that student loans attract simple interest and not compound interest.

After the bank consolidates it, the interest system changes to compounding.

The total interest is computed by applying the annual percentage rate (APR) to the principal and the loan term.  The result is added to the principal to obtain the total payment for each loan.

The total payment is divided by the loan period to get the monthly payments.

But for the consolidated loan by the bank, we can use an online finance calculator to determine the monthly payments and total payment over the loan term as follows.

                                 Loan A        Loan B         Loan C          Total

Student loan            $12,000      $18,000       $13,500     $43,500

APR                             7.5%               8%              9%

Loan term                 17 years      22 years     12 years

Period in months        204              264           144

Total interests         $15,300      $31,680       $14,580      $61,560

Total amount          $27,300     $49,680     $28,080    $105,060

Monthly payments $133.82        $188.18      $195.00      $517.00

Consolidated Loans:

Total amount of loans = $43,500 ($12,000 + $18,000 + $13,500)

Bank APR = 8%

Loan term = 22 years

N (# of periods) = 264 months (22 years x 12)

I/Y (Interest per year) = 8%

PV (Present Value) = $43,500

FV (Future Value) = $0

What is Solution of Root Equations?

An Equations with roots , such as the square root cannot be solved until its root is eliminated. Once we have isolated the square root on one side, we can eliminate it by raising both sides of the equation to powers equal to the square root. For example, if the square root is only one-sided, we can square both sides. We have , An airline offers daily flights between Chicago and Denver. Cost function of flight is,

C = 0.2x + 1

where x represents the number of passengers (in thousands) in flight.

To calculate how many passengers flew each day in June, we need to set the function to 2.5 (since the cost is in millions of dollars) and solve for the variables. This means taking the square root equal to 2.5. Therefore, to solve for the variables contained in its square root, we need to square both sides. This process and solution are described below,

√(0.2x + 1) = 2.5

Squaring both sides

=> (√(0.2x + 1) )² = ( 2.5 )²

=> 0.2x + 1 = 6.25

=> 0.2 x = 6.25 - 1 = 5.25

=> x = 5.25/0.2

=> x = 26.25

Now, we know that our variable i.e x measures passengers in thousands, so total passenger flew in June are 26.25 × 1000 = 26, 250 .

We can assume both of the figures display the ladder, ground, and wall forming a right triangle because the assignment is titled "apply the Pythagorean theorem", suggesting we should use the Pythagorean theorem and both figures are right triangles.

The Pythagorean theorem states that the sum of each leg squared is equal to the hypotenuse squared, or a^2 + b^2 = c^2, where "a" and "b" are legs and "c" is the hypotenuse.

At what height does the ladder in Figure 1 rest on the wall?

First, identify which sides are the legs and which is the hypotenuse. The hypotenuse is always the longest side and is the side opposite from the right angle. Thus, the hypotenuse in Figure 1 is the ladder length, and the two legs are the distance the ladder is from the wall and the height of the ladder against the wall. In other words, c = 10, a = 8, and b = the missing side length. Now, plug in the values to the Pythagorean theorem:

8^2 + b^2 = 10^2

64 + b^2 = 100

b^2 = 36

b = 6

The height at which the ladder in Figure 1 rests on the wall is 6 ft.

Approximately how much higher up the wall does the ladder in Figure 2 rest compared to the ladder in Figure 1?

We can set up the equation: Figure 2 ladder height - Figure 1 ladder height. We already know how where the ladder height of Figure 1 is, so we only need to solve for the ladder height in Figure 2 to get the result. Applying the same method as in the previous problem, we can input the values of Figure 2 into the Pythagorean theorem:

4^2 + b^2 = 10^2

16 + b^2 = 100

b^2 = 84

b = sqrt84

b ~ 9 ft

Now, we can find the difference between the Figure 2 ladder height and Figure 1 ladder height to get the answer to the question:

9 ft - 6 ft = 3 ft

Last year, Reagan grew 9/10 of an inch and her brother grew 2/5 of an inch. How much more did Reagan grow than her brother?

Answers

Reagan will grow 1/2 inch than her brother if Reagan grew 9/10 of an inch and her brother grew 2/5 of an inch by using ratio and proportion concept,

What is ratio and proportion?

When b does not equal 0, an ordered pair of numbers a and b, represented as a / b, is said to be a ratio. Two ratios are set to be equal in an equation called a proportion. For instance, if there is 1 boy and 3 girls, the ratio would be written as 1: 3 (there are 3 girls for every boy), meaning that there are 1 in 4 boys and 3 in 4 girls.

A: b a/b is the ratio formula, which may be used to calculate any two values. A:b::c:da:b::c:da, on the other hand, is how the percentage formula is written.

Given,

The height grown by Reagan=9/10 inch

The height grown by Reagan brother=2/5 inch

(9/10)-(2/5)

=1/2 inch

Therefore, Reagan will grow 1/2 inch than her brother.

Therefore,

What is the equation for the hyperbola shown?

Answers

The hyperbola's standard equation is [(x2/a2) - (y2/b2)] = 1, where X denotes the transverse axis and Y denotes the conjugate axis.

Define hyperbola.

A hyperbola is a particular kind of smooth curve that lies in a plane and is classified by its geometric characteristics or by equations for which it is the solution set. A hyperbola is made up of two mirror images of one another that resemble two infinite bows. These two sections are known as connected components or branches. A hyperbola is a geometric shape in mathematics where the difference between the lengths from any point on the figure to two fixed locations is a constant (the Greek letter o literally means "overshooting" or "excess"). We refer to the two fixed spots as foci (plural of focus).
