Prolific will bike 2 miles to get to the mechanic at the 6th gas station if the pattern continues.

Assuming the rate remains constant, we can use the equation d = rt, where d is the distance, r is the rate, and t is the time. In this case, we want to find the equation to determine the distance of the Nth gas station.

Let's analyze the given information:

The first gas station is 1.5 miles away.

From the second gas station onwards, each gas station is located at a distance 0.1 miles greater than the previous one.

Based on this pattern, we can write the equation for the distance of the Nth gas station as follows:

d = 1.5 + 0.1(N - 1)

B. To find the distance Prolific will bike to get to the 6th gas station, we can substitute N = 6 into the equation from part A:

d = 1.5 + 0.1(6 - 1)

= 1.5 + 0.1(5)

= 1.5 + 0.5

= 2 miles

Step-by-step explanation:

There are 6 family members over 3 years old.

Let's assume that the number of family members over 3 years old is "x".

The cost of admission for each family member over 3 years old is $3.25. Since the twins are 6 months old, they are not counted in the total cost of admission. Therefore, the total cost of admission for the family, including the twins, is $19.50.

The equation representing the total cost of admission can be set up as:

3.25x = 19.50

To find the value of "x," we can divide both sides of the equation by 3.25:

x = 19.50 / 3.25

x = 6

We are given the 95% confidence interval for the population mean of the change in AHE between 1992 and 2008 as [4.393, 9227].

This means that if we were to take multiple random samples and compute the confidence intervals for the change in AHE using the same method, approximately 95% of those intervals would contain the true population mean.

CI = X ± z* (s/√n)

where X is the sample mean, s is the sample standard deviation, n is the sample size, and z* is the critical value of the standard normal distribution for the desired confidence level.

However, we can conclude that the confidence interval has a lower bound of 4.393 and an upper bound of 9227, which means that we are 95% confident that the population mean of the change in AHE between 1992 and 2008 falls between these two values.

The functions that are solutions of the differential equation y''?4y'+4y=e^t are: (B) y=e^(2t)+te^t & (E) y=e^(2t)+e^t.The given differential equation is, y''+4y'+4y=e^t ...(1)

We have to find the solutions of the differential equation. Let's solve the differential equation:(1) => r²+4r+4=0Now, solve the quadratic equation using the quadratic formula: r= (-(4)+√((4)²-4(1)(4))) / 2(1)= -2 (repeated)So, the solution of the corresponding homogeneous equation is:(2) yh= (c₁+c₂t)e^(-2t) ---------------(2)Now, we have to find a particular solution of the non-homogeneous differential equation (1).

Let, yp= Ae^t. Now, yp'= Ae^t, yp''= Ae^t. Substitute yp and its derivatives in the equation (1):yp''+4yp'+4yp= e^tAe^t+4Ae^t+4Ae^t= e^t9Ae^t= e^tA= 1/9Therefore, the particular solution is,(3) yp= e^t/9 ------------(3)

Hence, the general solution of the given differential equation is,(4) y= yh+yp= (c₁+c₂t)e^(-2t) + e^t/9Now, substitute the initial conditions in the general solution to get the constants c₁ and c₂:Let, y(0)=0 and y'(0)=0, then,c₁= -1/9 and c₂= 5/9Finally, the solution of the differential equation y''?4y'+4y=e^t is,(5) y= -(1/9)e^(-2t) + (5/9)te^(-2t) + e^t/9 =(e^(2t)+te^(2t))/9+ e^t ...

Suppose you have two random samples, A and B from the same population with population mean \($\mu$\).

Sample A B has \($n_{a}$\) observations with the sample mean \($\bar{A}$\)

and sample B has \($\eta_{b}$\) observations with the sample mean \($\bar{B}$\)\(\bar{B}\)

\(\Rightarrow \quad E(\bar{A})=\mu \text { and } E(\bar{B})=\mu\)

since sample mean is an unbiased estimator of the population mean

\(1) $\begin{aligned} \hat{\theta}_{1} &=\frac{1}{4} \bar{A}+\frac{1}{2} \bar{B} \\ \Rightarrow E\left(\hat{\theta}_{1}\right) &=\frac{1}{4} E(\bar{A})+\frac{1}{2} E(\bar{B}) \\ &=\frac{1}{4} \mu+\frac{1}{2} \mu \\ \Rightarrow E\left(\hat{\theta}_{1}\right) &=\frac{3}{4} \mu \end{aligned}$\)

\($\hat{\theta}_{1}$\) is not unbiased estimator of population mean \(\mu\).

Bias \($\left(\hat{\theta}_{1}\right) =E\left(\hat{\theta}_{1}\right)-\mu \\\)

\(=\frac{3}{4} \mu-\mu \\\)

Bias \($\left(\hat{\theta}_{1}\right) &=-\frac{\mu}{4}\)

\(2) $\begin{aligned} \hat{\theta}_{2} &=\frac{\eta_{a}}{n_{a}+\eta_{b}} \bar{A}+\frac{\eta_{b}}{n_{a}+n_{b}} \bar{B} \\ \Rightarrow E\left(\hat{\theta}_{2}\right) &=\frac{n_{a}}{n_{a}+n_{b}} E(\bar{A})+\frac{n_{b}}{n_{a}+n_{b}} E(\bar{B}) \\ &=\frac{n_{a}}{n_{a}+n_{b}} \mu+\frac{n_{b}}{n_{a}+n_{b}} \mu \end{aligned}$\)

\(\begin{aligned}=\frac{h_{a}+h_{b}}{n_{a}+h_{b}} \mu \\E\left(\hat{\theta}_{2}\right) &=\mu\end{aligned}\)

\($\hat{\theta}_{2}$\) is an unbiased estimator for population mean \($\mu$\)

So, the Bias \($\left(\hat{\theta}_{2}\right)=E\left(\hat{\theta}_{2}\right)-\mu=\mu-\mu=0$\)

\(Bias}\left(\hat{\theta}_{2}\right)=0\)

The equity of the entity, according to the basic accounting equation, is R6 000. The basic accounting equation is Assets = Liabilities + Equity. To find the equity of the entity, we need to subtract the total liabilities from the total assets.

Bank balance: R5 000

Machinery balance: R3 000

Trade payables: R2 000

Total assets = Bank + Machinery

            = R5 000 + R3 000

            = R8 000

Total liabilities = Trade payables

                 = R2 000

Equity = Total assets - Total liabilities

      = R8 000 - R2 000

      = R6 000

Therefore, the equity of the entity, according to the basic accounting equation, is R6 000.

1) P(ANB) = 0.1

2) We cannot determine P(AUB) using the given information.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event

To find P(ANB), we can use the formula: P(ANB) = P(A) + P(B) - P(AUB).

Plugging in the given values, we get:

P(ANB) = 0.3 + 0.4 - 0.6

= 0.1

Therefore, P(ANB) is 0.1.

2)Since A and B are not mutually exclusive events, we cannot use the formula P(AUB) = P(A) + P(B) - P(ANB) to find P(AUB). Instead, we need to use the formula: P(AUB) = P(A) + P(B) - P(ANB) only if A and B are mutually exclusive events.

Therefore, we cannot determine P(AUB) using the given information.

Answer:

Todd has 540540 songs in his playlist.

Vlad has 270270 songs in his playlist.

Becca has 162162 songs in her playlist.

Step-by-step explanation:

# of songs Todd has = T

# of songs Vlad has = V

# of songs Becca has = B

1) Todd has twice as many songs in his playlist as Vlad:

T=2V

2) Becca has three times as many songs in her playlist as Todd:

B=3T

3) All three people have a total of 243243 songs in their playlists:

T+V+B=243243

Because T=2V then you can substitute T as 2V in the second equation:

B=3(2V)

B=6V

Now in the final equation, you can substitute everything for V:

2V+V+6V=243243

9V=243243

V=27027

Now substitute for T:

T+1/2T+3T=243243

9/2T=243243

T=54054

Now substitute for B:

1/3B+1/6B+B=243243

3/2B=243243

B=162162
