Answer:

$-54\ \frac{ft}{sec}$

Step-by-step explanation:

we know that

To find out the mean change of altitude, divide the total change by the amount of time it takes

so

$-\frac{378}{7}=-54\ \frac{ft}{sec}$ ---> is negative because the airplane is descending

Suppose I have an urn with 9 balls: 4 green, 3 yellow and 2 white ones. I draw a ball from the urn repeatedly with replacement.

Mrrafil [7]

Answer:

$E(X_n)=\frac{2(n-1)}{27}$

$E(y)=\frac{14}{9}$

Step-by-step explanation:

From the question we are told that:

Sample size n=9

Number of Green $g=4$

Number of yellow $y=4$

Number of white $w=4$

Probability of Green Followed by yellow P(GY) ball

$P(GY)=\frac{4}{9}*\frac{3}{9}$

$P(GY)=\frac{4}{27}$

Generally the equations for when n is even is mathematically given by

$Probability of success P(S)=\frac{4}{27}$

$Probability of Failure P(F)=\frac{27-4}{27}$

$Probability of Failure P(F)=\frac{23}{27}$

Therefore

$E(X_n)=\frac{n}{2}*P$

$E(X_n)=\frac{n}{2}*\frac{4}{27}$

$E(X_n)=\frac{2n}{27}$

Generally the equations for when n is odd is mathematically given by

$\frac{n-1}{2}$

$E(X_n)=\frac{n-1}{2}*\frac{4}{27}$

$E(X_n)=\frac{2(n-1)}{27}$

b)

Probability of drawing white ball

$P(w)=\frac{2}{9}$

Therefore

$E(w)=\frac{1}{p}$

$E(w)=\frac{1}{\frac{2}{9}}$

$E(w)=\frac{9}{2}$

Therefore

$E(y)=[E(w)-1]\frac{4}{9}$

$E(y)=[\frac{9}{2}-1]\frac{4}{9}$

$E(y)=\frac{14}{9}$

Miller's Bank is offering a new certificate of deposit (CD) with daily compounding and an annual interest rate of 4.65% for a te

ladessa [460]

Answer:

$20,086.35

Step-by-step explanation:

To calculate the maturity value by compound interest, we will use the formula

$A=P(1+\frac{r}{n})^{nt}$

where,

A = Maturity amount

P = Principal amount = $10,000

r = rate of interest = 4.65% = 0.0465

n = number of compounding periods = 365

t = time in years = 15 years

Now substituting the values,

$A=10,000(1+\frac{0.0465}{365})^{(365)(15)}$

= $10,000(1+0.000127)^{(365)(15)}$

$=10,000(1.000127^{5475})$

= 10,000(2.008635)

= 20086.353758 ≈ $20,086.35

The final value of your investment would be $20,086.35.
