A colony of 85 bacteria doubles in size every 126 minutes. What will the population be 378
minutes from now?
Answers
Answer:
680 Bacteria
Step-by-step explanation:
378 is evenly divisible by 126, which is equal to 3.
The first 126 minutes, the 85 bacteria will double to 170 bacteria.
The second 126 minutes (252 minutes total), the 170 bacteria will double to 340 bacteria.
The final 126 minutes (378 minutes total), the 340 bacteria will double to 680 bacteria total.

Answers
Answer:
Yo mean correct way??
yo can divide minute by 60 to convert minute into hour
For example
To convert 10 minute into hour. then we should divide 10 by 60. 10/60
Answer:
In any conversion you have to establish ratios (or rates) for the different units being converted.
The process will be performed by a series of multiplications that will cancel out the "unwanted" units.
multiplication by one (1) does not change the value in an equation.
you have to multiply by a "series of ones" that take into account the units being converted..
for example
1 minute/60 seconds or 1 inch = 2.54 cm or 1 day = 24 hours
in your problem you have minutes... lets say you have 100 minutes
100 minutes * 1 hour minutes cancel and you have 100/60 = 1 \(\frac{2}{3}\) hrs

Firm 1 chooses a function, and firm 2 chooses a number.
b.
Both firms chooses numbers.
c.
Both firms choose functions.
d.
Firm 1 chooses a number, and firm 2 chooses a function.
Answers
In the Subgame Perfect Equilibrium of a Stackelberg model, firm 1 chooses a number, and firm 2 chooses a function. Therefore, option (d) is the correct answer.
The Subgame Perfect Equilibrium (SPE) is a solution concept in game theory that analyzes strategic decision-making in sequential games. In a Stackelberg model, firm 1 acts as the leader and sets its output level first, followed by firm 2 as the follower, who observes firm 1's output before making its decision.
In the Subgame Perfect Equilibrium of this model, firm 1 chooses a number (output level) while firm 2 chooses a function (strategy). This implies that firm 1's decision is made independently as a quantity, and firm 2, observing firm 1's choice, formulates its strategy based on that information.
Therefore, option (d) is the correct answer: Firm 1 chooses a number, and firm 2 chooses a function in the Subgame Perfect Equilibrium of a Stackelberg model.

A simple random sample with n = 56 provided a sample mean of 22.5 and a sample standard deviation of 4.4. (Round your answers to one decimal place.)
a) Develop a 90% confidence interval for the population mean.
b) Develop a 95% confidence interval for the population mean.
c) Develop a 99% confidence interval for the population mean.
Answers
a) The 90% confidence interval for the population mean is approximately (21.52, 23.48).
b) The 95% confidence interval for the population mean is approximately (21.322, 23.678).
c) The 99% confidence interval for the population mean is approximately (20.926, 24.074).
To develop confidence intervals for the population mean, we can use the formula:
Confidence Interval = sample mean ± (critical value * standard error)
where the standard error is equal to the sample standard deviation divided by the square root of the sample size.
a) For a 90% confidence interval, we need to find the critical value corresponding to a confidence level of 90%. The critical value can be obtained from the t-distribution table with (n-1) degrees of freedom. Since the sample size is 56, the degrees of freedom is 56-1 = 55.
From the t-distribution table, the critical value for a 90% confidence interval with 55 degrees of freedom is approximately 1.671.
The standard error can be calculated as:
Standard Error = sample standard deviation / sqrt(sample size)
Standard Error = 4.4 / sqrt(56)
Standard Error ≈ 0.5882
Now we can calculate the confidence interval:
Confidence Interval = 22.5 ± (1.671 * 0.5882)
Confidence Interval = 22.5 ± 0.9816
Confidence Interval ≈ (21.52, 23.48)
b) For a 95% confidence interval, the critical value for 55 degrees of freedom is approximately 2.004 (obtained from the t-distribution table).
Standard Error = 4.4 / sqrt(56) ≈ 0.5882
Confidence Interval = 22.5 ± (2.004 * 0.5882)
Confidence Interval = 22.5 ± 1.178
Confidence Interval ≈ (21.322, 23.678)
c) For a 99% confidence interval, the critical value for 55 degrees of freedom is approximately 2.678 (obtained from the t-distribution table).
Standard Error = 4.4 / sqrt(56) ≈ 0.5882
Confidence Interval = 22.5 ± (2.678 * 0.5882)
Confidence Interval = 22.5 ± 1.574
Confidence Interval ≈ (20.926, 24.074)

This is a right triangle trig problem. Picture a right triangle. The height of the triangle is the height of the lighthouse, your distance from the base of the lighthouse is what we are solving for, and the reference angle is 2 degrees, which is the angle of inclination from where you stand to the top of this lighthouse. We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:

You invested $1200 into an account that earned interest that was compounded semiannually. After 10 years, the amount in the account is now $4034.22. What was the interest rate of the investment?
Answers
the interest rate of investment is r = 6.25 %.
Principal amount = $ 1200
Time = 10 years
Since the interest is compounded semi annually, the time period will become:
n = 2 × 10 = 20
Amount after 10 years = $ 4034.22
Using the formula for compound interest, we get that:
A = P (1 + r)ⁿ
Substitute the values, we get that:
4034.22 = 1200 ( 1 + r)²⁰
3.36185 = ( 1 + r)²⁰
( 1 + r)²⁰ = 3.36185
( 1 + r) = 1.06245
r = 0.0625
Interest Rate will be:
r = 6.25 %
Therefore, we get that the interest rate of investment is r = 6.25 %.

use the method of laplace transforms to find the solution y(t) to the initial value problem y 00 2y 0 2y
Answers
To find the solution y(t) to the initial value problem y'' + 2y' + 2y = 0, we can use the method of Laplace transforms.
Step 1: Take the Laplace transform of both sides of the differential equation.
The Laplace transform of y''(t) is s^2Y(s) - sy(0) - y'(0), where Y(s) is the Laplace transform of y(t).
The Laplace transform of y'(t) is sY(s) - y(0).
The Laplace transform of y(t) is Y(s).
Step 2: Substitute the Laplace transforms into the differential equation.
We get (s^2Y(s) - sy(0) - y'(0)) + 2(sY(s) - y(0)) + 2Y(s) = 0.
Step 3: Solve for Y(s).
Rearrange the equation to solve for Y(s):
s^2Y(s) + 2sY(s) + 2Y(s) - sy(0) - y'(0) - 2y(0) = 0.
Combining like terms, we have:
(Y(s)(s^2 + 2s + 2)) - s(y(0) + 2y(0)) - y'(0) = 0.
Simplifying further, we have:
Y(s)(s^2 + 2s + 2) = s(3y(0)) + y'(0).
Dividing both sides by (s^2 + 2s + 2), we get:
Y(s) = (s(3y(0)) + y'(0))/(s^2 + 2s + 2).
Step 4: Inverse Laplace transform to find y(t).
To find y(t), we need to find the inverse Laplace transform of Y(s).
Using partial fraction decomposition, we can express Y(s) as:
Y(s) = A/(s^2 + 2s + 2) + B/(s^2 + 2s + 2).
To find the values of A and B, we can use the method of inverse Laplace transforms or solve the system of equations formed by equating the coefficients of the powers of s.
Once we have the partial fraction decomposition of Y(s), we can take the inverse Laplace transform to find y(t).
This step involves finding the inverse Laplace transforms of each term separately, which can be done using standard Laplace transform tables or by using the method of completing the square.
After finding the inverse Laplace transforms, we obtain the solution y(t) to the initial value problem y'' + 2y' + 2y = 0.
Please note that the specific values of y(0) and y'(0) need to be given in order to find the solution y(t) accurately.
