find the time in which birr 168.40 will earn a simple interest of birr 29.47 at 5% per year.​

Answers

It will take 3.5 years for birr 168.40 to earn a simple interest of birr 29.47 at 5% per year.

How to determine the time

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

Principal = 168.40

Rate = 5% = 0.05

Interest = 29.47

We can use the simple interest formula to solve this problem:

I = Prt

Where I is the interest earned, P is the principal amount, r is the annual interest rate as a decimal, and t is the time in years.

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

29.47 = 168.40 * 0.05 * t

So, we have

t = 29.47 / (168.40 * 0.05)

Evaluate

t = 3.5

Hence, the time is 3.5 years

Please help me, due soon, i will give brainliest!! pre-calc question: according to the intermediate value theorem, in what interval must cos x= 2^x-6 have a solution? show work!

Answers

According to the Intermediate Value Theorem, if a function f(x) is continuous on a closed interval [a, b], and if f(a) and f(b) have opposite signs, then there exists at least one value c in the interval (a, b) such that f(c) = 0. According to the Intermediate Value Theorem, the interval in which the equation cos(x) = 2^(x-6) must have a solution is (0, π/2).

Let's apply this theorem to the function f(x) = cos(x) - 2^(x-6).
First, we need to find two values a and b such that f(a) and f(b) have opposite signs. Let's start with a = 0 and b = π/2.
f(0) = cos(0) - 2^(0-6) = 1 - 1/64 > 0
f(π/2) = cos(π/2) - 2^(π/2-6) = 0 - 1/4 < 0
Since f(a) and f(b) have opposite signs, there exists at least one value c in the interval (0, π/2) such that f(c) = 0. Therefore, the equation cos(x) = 2^(x-6) has at least one solution in the interval (0, π/2).
To summarize, according to the Intermediate Value Theorem, the interval in which the equation cos(x) = 2^(x-6) must have a solution is (0, π/2).

Think of a vending machine on campus. The vending machine has a coin collector that should be emptied regularly. In the past, the vending machine company emptied the coin collector every 14 days, and recorded the weight of the coin collector when it is emptied. In the past 100 visits, the average weight of the coin collector was 22 pounds and the standard deviation was 8.
If the coin collector is full, the vending machine is unusable. But emptying the collector is also an expense. The company finds that it is optimal to empty a coin collector when it weighs 20 pounds. The company wants to test the following hypotheses:
Null hypothesis: the mean weight of the coin collector emptied every 14 days is 20 pounds.
Alternative hypothesis: the mean weight of the coin collector emptied every 14 days is not 20 pounds.
Find the t-statistic of the test, and determine if the null hypothesis is rejected at the significance level of 5%. (Round the t-statistic to the second decimal place.)
a. t-statistic is 2, so the null hypothesis is not rejected.
b. t-statistic is 1.25, so the null hypothesis is not rejected.

Answers

The sampling distribution of the mean is approximately normal, follows the Central Limit Theorem, has a mean equal to the population mean, and decreases in variability with larger sample sizes.

The sampling distribution of the mean is a distribution that represents the possible values of the sample means obtained from repeated sampling of a population. It tends to follow a normal curve shape, regardless of the shape of the population distribution, as long as the sample size is large enough due to the Central Limit Theorem.

The mean of the sampling distribution is equal to the population mean, making it an unbiased estimator. Additionally, the standard deviation of the sampling distribution, known as the standard error, decreases as the sample size increases, indicating that larger samples lead to more precise estimates of the population mean with reduced variability in the sample means.

On average number of beds filled in the maternity ward at any given time = 5

Total patient days per year is,

⇒ Total patient days = Average number of beds filled x Number of days in a year

Since there are 365 days in a year,

⇒Total patient days = 5 x 365

                                 = 1,825

Use the formula,

Average length of stay = Total patient days / Total number of patients

⇒Average length of stay = 1,825 / 1,500

The given points are (-5, 1) and (1, 3)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Then,

(y - 1) / (x - (-5)) = (3 - 1) / (1 - (-5))

Answer for the entire contract. For example, if the profit is .01 per unit and the contract is for 5000 units, then the profit on the contract is 50.

Answers

The profit for the option writer is $3,900.

In this scenario, the option writer sold a put option on the Canadian dollar with an exercise price of USD 0.76/CAD. The premium received for the option was $0.039/CAD. The contract size is CAD 100,000, and the spot price at maturity is $0.76/CAD. However, since the spot price at maturity is equal to the exercise price of $0.76/CAD, the option is not exercised. As the option writer, the profit is determined by the premium received. In this case, the premium received per contract is $0.039/CAD. Multiplying this by the contract size of CAD 100,000, we get $3,900.

It's important to note that if the spot price at maturity had been lower than the exercise price, the option would have been exercised, resulting in a loss for the option writer equal to the difference between the exercise price and the spot price, multiplied by the contract size.

Step-by-step explanation:

Question 1

1.  Solve for s:

\(\implies 2r = \dfrac{5s}{2}-\dfrac{s}{4}\)

\(\implies 2r = s\left(\dfrac{5}{2}-\dfrac{1}{4}\right)\)

\(\implies 2r = s\left(\dfrac{10}{4}-\dfrac{1}{4}\right)\)

\(\implies 2r = s\left(\dfrac{9}{4}\right)\)

\(\implies 4(2r) = 9s\)

\(\implies 8r = 9s\)

\(\implies s=\dfrac{8r}{9}\)

2.  When r = ⁹/₂ :

\(\implies s=\dfrac{8\left(\frac{9}{2}\right)}{9}\)

\(\implies \dfrac{8}{9} \times \dfrac{9}{2}\)

\(\implies \dfrac{8 \times9}{9 \times2}\)

\(\implies s=\dfrac{72}{18}\)

\(\implies w+z=\dfrac{x}{y}\)

\(\implies y(w+z)=x\)

\(\implies x=y(w+z)\)

2.  When x = -8,  y = -5,  z = 6:

The given differential equation is a second-order homogeneous linear differential equation with constant coefficients. The characteristic equation is r^2 + 2 = 0, which has roots r = ±sqrt(2)i. Since the roots are complex conjugates, the general solution can be written as u(t) = c1*cos(sqrt(2)t) + c2*sin(sqrt(2)t), where c1 and c2 are constants determined by the initial conditions.

To find the particular solution for the non-homogeneous term cos(t), we can use the method of undetermined coefficients. Since the characteristic equation has imaginary roots, the guess for the particular solution must be of the form u(t) = Acos(t) + Bsin(t), where A and B are constants to be determined. Taking the derivatives of this guess and substituting them into the differential equation, we can solve for A and B.

The final solution is the sum of the homogeneous and particular solutions: u(t) = c1*cos(sqrt(2)t) + c2*sin(sqrt(2)t) + (1/2)*(cos(t) - sqrt(2)*sin(t)). This is the general solution to the given differential equation.

Answers

The maximum number of possible effects that could be tested in a 2x2x2 factorial design with 3 main effects, 3 two-way interactions, and 1 three-way interaction is 7.

In a 2 x 2 x 2 factorial design, we can test the following maximum number of possible effects:
Main effects:

There are 3 main effects in this design, one for each factor (A, B, and C). You would analyze the effect of each factor independently on the outcome variable.

Two-way interactions:

There are 3 possible two-way interactions that can be tested in this design: AxB, AxC, and BxC.

These interactions examine the combined effects of two factors on the outcome variable.
Three-way interactions:

There is 1 possible three-way interaction that can be tested in this design: AxBxC.

This interaction examines the combined effect of all three factors (A, B, and C) on the outcome variable.
