Step-by-step explanation:
in how many years will Rs.1200 at the rate of 15% interest amount to Rs. 1740
Answers
Find the interest amount.
\(I=1740-1200=540\)
Use the formula for simple interest.
\(I=prt/100\)
Solve for t.
\(540=1200 \times 15\% \times t\)
\(540=1200 \times \frac{15}{100} \times t\)
\(540=180t\)
\(t=\frac{540}{180}\)
\(t=3\)
3 years.The number of years will be 3 for Rs.1200 at the rate of 15% interest amounting to Rs. 1740.
What is simple interest?
Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.
Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.
Given that Rs.1200 at the rate of 15% interest amount to Rs. 1740. The number of years will be calculated as:-
SI = ( P x R x T ) / 100
1740 - 1200 = ( 1200 x 15 x T ) / 100
T = ( 540 x 100 ) / ( 1200 x 15)
T = 3 years
Hence, the time will be 3 years.

In a random sample of 200 school district residents, 94 stated they are in favor of starting the school day 15 minutes later each day. Calculate a 90% confidence interval for the true proportion of district residents who are in favor of starting the day later
Answers
The 90% confidence interval for the proportion of district residents in favor of starting the school day 15 minutes later is (0.392, 0.548). The true proportion is estimated to lie within this interval with 90% confidence.
To calculate the 90% confidence interval for the true proportion of district residents who are in favor of starting the school day 15 minutes later, we can use the following formula:
CI = p ± z*(√(p*(1-p)/n))
where:
CI: confidence interval
p: proportion of residents in favor of starting the day later
z: z- score based on the confidence level (90% in this case)
n: sample size
First, we need to calculate the sample proportion:
p = 94/200 = 0.47
Next, we need to find the z- score corresponding to the 90% confidence level. Since we want a two-tailed test, we need to find the z- score that cuts off 5% of the area in each tail of the standard normal distribution. Using a z-table, we find that the z- score is 1.645.
Substituting the values into the formula, we get:
CI = 0.47 ± 1.645*(√(0.47*(1-0.47)/200))
Simplifying this expression gives:
CI = 0.47 ± 0.078
Therefore, the 90% confidence interval for the true proportion of district residents who are in favor of starting the school day 15 minutes later is (0.392, 0.548). We can be 90% confident that the true proportion lies within this interval.

Assume the probability of Lukas Podolski scores in a soccer match is 25%.
a) Assuming that Lukas performs independently in different matches, what is the probability that Lukas will score in world cup quarter final match and semifinal match? Use 4 decimal places _______
b) Assume again that Lukas performs independently in different games, what is the probability of Lukas scoring in quarter final OR semi final? Use 4 decimal places _______
Answers
(a) The probability that Lukas Podolski will score in both the World Cup quarter-final and semi-final matches is 0.0625 (or 6.25%).
(b) The probability of Lukas Podolski scoring in either the World Cup quarter-final OR the semi-final match is 0.5 (or 50%).
What is Probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated.
a) To find the probability that Lukas Podolski will score in both the World Cup quarter-final and semi-final matches, we multiply the probabilities of him scoring in each match since the events are independent.
Probability of scoring in the quarter-final match = 0.25 (or 25%)
Probability of scoring in the semi-final match = 0.25 (or 25%)
Probability of scoring in both matches = 0.25 * 0.25 = 0.0625
Therefore, the probability that Lukas Podolski will score in both the World Cup quarter-final and semi-final matches is 0.0625 (or 6.25%).
b) To find the probability of Lukas Podolski scoring in either the quarter-final OR the semi-final match, we can use the principle of addition. Since the events are mutually exclusive (he can't score in both matches simultaneously), we can simply add the probabilities of scoring in each match.
Probability of scoring in the quarter-final match = 0.25 (or 25%)
Probability of scoring in the semi-final match = 0.25 (or 25%)
Probability of scoring in either match = 0.25 + 0.25 = 0.5
Therefore, the probability of Lukas Podolski scoring in either the World Cup quarter-final OR the semi-final match is 0.5 (or 50%).

there are 52 contacts in your phone. the only family members' numbers you have are your dad's, mom's, and brother's. what are the odds of selecting a number in your phone that is not your family?
Answers
The odds of selecting a number in your phone that is not your family are approximately 0.9423 or 94.23%.
To calculate the odds of selecting a number in your phone that is not your family, we need to determine the number of contacts that are not family members and divide it by the total number of contacts.
Given that you have 52 contacts in total, and you have the numbers of your dad, mom, and brother, we can assume that these three contacts are family members. Therefore, we subtract 3 from the total number of contacts to get the number of non-family contacts.
Non-family contacts = Total contacts - Family contacts
Non-family contacts = 52 - 3
Non-family contacts = 49
So, you have 49 contacts that are not family members.
To calculate the odds, we divide the number of non-family contacts by the total number of contacts.
Odds of selecting a non-family number = Non-family contacts / Total contacts
Odds of selecting a non-family number = 49 / 52
Simplifying the fraction:
Odds of selecting a non-family number ≈ 0.9423
Therefore, the odds of selecting a number in your phone that is not your family are approximately 0.9423 or 94.23%.

Find a plane containing the point (6,-6,5) and the line of intersection of the planes -6 x+y+7 z=-15 and 5 x+4 y-7 z=-26 Question Help: Message instructor
Answers
A plane containing the point (6, -6, 5) and the line of intersection of the planes -6x + y + 7z = -15 and 5x + 4y - 7z = -26 is 23x - 8y + 10z = -84.
To find a plane that contains a given point and the line of intersection of two planes, we can use the following steps:
1. Find the direction vector of the line of intersection by taking the cross product of the normal vectors of the two planes.
2. Determine a specific point on the line of intersection by setting one of the variables (such as z) to a value and solving for the remaining variables using the equations of the planes.
3. Use the point on the line and the direction vector to form the equation of the plane using the point-normal form.
First, let's find the direction vector of the line of intersection. The normal vectors of the given planes are [ -6, 1, 7] and [5, 4, -7]. Taking their cross product gives us the direction vector [ -59, 13, -34].
Next, we need to find a specific point on the line of intersection. We can choose any of the two planes to solve for the variables. Let's use the first plane, -6x + y + 7z = -15. If we set z = 0, we can solve the resulting system of equations to find the point (x, y, z) on the line: -6x + y = -15. By substituting y = -6x - 15 into the second plane equation, we obtain -25x - 57z = -11. Solving this system of equations, we find x = -84/23, y = -528/23, and z = 0.
Now, we have a point (-84/23, -528/23, 0) on the line of intersection and the direction vector [ -59, 13, -34]. Using the point-normal form, we can write the equation of the plane:
23x - 8y + 10z = -84.
This equation represents the plane that contains the given point and the line of intersection of the two planes.

The speed equals 10.0 m/s at t = 2.35 s.
The velocity v of a particle moving in the xy plane is given by v=(5.50t−5.00t2)i^+9.00 j^, with v in meters per second and (>0) in seconds. At t=1.40 s and in unit-vector notation, the x component and y component of the acceleration are
(a) -5.00i^+0.00j^ m/s^2 and
(b) 9.00i^+0.00j^ m/s^2, respectively.
Here's the solution to the remaining parts of the problem:
(c) When (if ever) is the acceleration zero
To find when the acceleration is zero, we need to determine the time when dv/dt = 0. Differentiating the velocity vector with respect to time, we getdv/dt = (5.50 - 10.00t) i^At dv/dt = 0,5.50 - 10.00t = 0t = 0.55 s
Hence, the acceleration is zero at t = 0.55 s.
(d) At what positive time does the speed equal 10.0 m/s
To determine the time when the speed equals 10.0 m/s, we need to solve the equation v = 10.0 m/s.
Substituting the given values, we get10.0 = (5.50t - 5.00t^2)^2 + 9.00^2
On solving the above quadratic equation, we gett = 2.35 s and t = 0.15 s
At t = 0.15 s, the velocity vector points downwards and at t = 2.35 s, the velocity vector points upwards.
Hence, the speed equals 10.0 m/s at t = 2.35 s.

Answers
Some likely questions can be (i)What is the intuition behind Stirling's formula? (ii) How is the gamma function related to Stirling's formula? and many more,
Some likely questions on the proof of Stirling's formula, which approximates the factorial of a large number, may include:
What is the intuition behind Stirling's formula? How is the gamma function related to Stirling's formula? Can you explain the derivation of Stirling's formula using the method of steepest descent? What are the key steps in proving Stirling's formula using integration techniques? Are there any assumptions or conditions necessary for the validity of Stirling's formula?
The proof of Stirling's formula typically involves techniques from calculus and complex analysis. It often begins by establishing a connection between the factorial function and the gamma function, which is an extension of factorials to real and complex numbers. The gamma function plays a crucial role in the derivation of Stirling's formula.
One common approach to proving Stirling's formula is through the method of steepest descent, also known as the Laplace's method. This method involves evaluating an integral representation of the factorial using a contour integral in the complex plane. The integrand is then approximated using a stationary phase analysis near its maximum point, which corresponds to the dominant contribution to the integral.
The proof of Stirling's formula typically requires techniques such as Taylor series expansions, asymptotic analysis, integration by parts, and the evaluation of complex integrals. It often involves intricate calculations and manipulations of expressions to obtain the desired result. Additionally, certain assumptions or conditions may need to be satisfied, such as the limit of the factorial approaching infinity, for the validity of Stirling's formula.

Answers
The probability that Chase is selected for lighting, Jaden is selected for props, and Emelina for spotlighting in the high school production of A Raisin in the Sun is: \[ P(\text{Chase for lighting}) \times P(\text{Jaden for props}) \times P(\text{Emelina for spotlighting}) \]
What is the probability of Chase being selected for lighting, Jaden for props, and Emelina for spotlighting?In this scenario, there are 18 students in each freshman English class. The crew members are decided at random, which means each student has an equal chance of being selected for a particular role.
To calculate the probability, we need to determine the individual probabilities for each student to be selected for their respective roles. Assuming there are no restrictions or biases in the selection process, each student has a 1 in 18 chance of being chosen for any given role.
Therefore, the probability of Chase being selected for lighting is \( \frac{1}{18} \), the probability of Jaden being selected for props is also \( \frac{1}{18} \), and the probability of Emelina being selected for spotlighting is \( \frac{1}{18} \).
Multiplying these probabilities together, we get:
\[ P(\text{Chase for lighting}) \times P(\text{Jaden for props}) \times P(\text{Emelina for spotlighting}) = \frac{1}{18} \times \frac{1}{18} \times \frac{1}{18} \]

A lump sum of $1000 is invested at 4.6% compounded continuously. (a) Write the function for the model that gives the future value of the investment in dollars after t years.
Answers
The investment would be worth about $1315.94. Similarly, we can find the future value at any other time by plugging in the appropriate value of t.
To find the future value of an investment that is compounded continuously, we can use the formula:
A = Pe^(rt)
Where A is the future value, P is the initial principal, r is the annual interest rate, and t is the time in years.
In this case, we have P = $1000, r = 0.046 (since the interest rate is 4.6%), and t is the number of years. Plugging these values into the formula, we get:
A = 1000*e^(0.046t)
This is the function for the model that gives the future value of the investment in dollars after t years. To find the future value at a specific time, we just need to substitute the value of t into the function and evaluate it. For example, if we wanted to find the value after 5 years, we would plug in t = 5:
A = 1000*e^(0.046*5) = 1000*e^(0.23) ≈ $1315.94
