Answer:

The amount Tobie invests in a bank, P = $25

The annual compound interest rate, i = 4%

a. The principal is amount invested in the bank, P = $25

The annual interest rate, i = 4%

b. The function that represents Tobie's account balance, A, after t years is given as follows;

\(A(t) = P \cdot (1 + i)^t\)

Where;

A(t) = The amount in the account after t years

P = The principal amount

i = The annual compound interest rate

t = The number of years

c. The values to place in the table are found as follows;

At t = 0, \(A(0) = 25 \times(1 + 0.04)^0\)  = 25

At t = 10, \(A(10) = 25 \times(1 + 0.04)^{10}\) = 37

The given table is presented as follows;

\(\begin{array}{ccc}t&&A(t)\\0&&25\\10&&37\end{array}\)

Answer:

A.) 4991/157216

B.) 2401/1336336

C.) 16399/314432

Step-by-step explanation:

Given the following :

Granny Smith = 23

Honey crisp = 14

Red delicious = 31

Probability = (number of required outcome / number of possible outcomes)

Number of possible outcomes = 23 + 14 + 31 = 68

With replacement :

A.) one of each :

P(granny Smith) × P(Honey crisp) × P(Red delicious)

P(granny Smith) = 23/68

P(Honey crisp) = 14/68 = 7/34

P(red delicious) = 31/68

(23/68 × 7/34 × 31/68) = 4991/157216

B) 4 honey crisp:

P(4 Honey crisp) = P(honey crisp) × P(honey crisp) × P(honey crisp) × P(honey crisp)

7/34 × 7/34 × 7/34 × 7/34 = 2401/1336336

C.) 2 granny Smith and 1 red delicious

P(granny Smith) × P(granny Smith) × P(red delicious)

23/68 × 23/68 × 31/68 = 16399/314432

95% t-interval for a population mean is Confidence Interval = [14.446, 15.554]

In statistics, estimating the value of a population parameter, like a population proportion or a population mean, is a common goal.

We normally choose a small, random sample to estimate these values, and then we compute the sample proportion or sample mean.

Then, in order to express our uncertainty over these estimations, we build a confidence interval.

To determine a confidence interval for a population proportion, we use the following formula:

The confidence Interval is equal to

Here is how to determine a population mean's 95% confidence interval:

The confidence Interval is equal to x z*(s/n).

Confidence Interval is equal to 15 1.96*(4/25).

Confidence Interval is equal to 15 1.568.

Interval of Confidence = [13.432, 16 .568]

Now imagine that we chose a 200-person sample size instead. Here is how we would determine the population's 95% confidence interval:

Confidence Interval = 15 ± 0.554

Step-by-step explanation:

The solution to this equation \(y" - 5y' + 4y = e^(3x)\) which is a non homogeneous differentia equation is  \(y(x) = c1 e^(4x) - (1/4) c1 e^(3x) + c2 e^(x) + (1/6) e^(4x)\), where c1, c2 are the arbitrary constants of  the integration.

The given equation is a non homogeneous second-order differential equation and to solve it using the method of variation of parameters, we must first find the the general solution of the corresponding homogeneous equation \(y" - 5y' + 4y = 0.\)

we have;

\(r^2 - 5r + 4 = 0\)

By factorization, it become;

(r - 4)(r - 1) = 0

With the roots as r = 4 and r = 1, The general solution of the homogeneous equation is given as;

\(y_h(x) = c1 e^(4x) + c2 e^(x)\)

Form of non homogenous equation is given as;

\(y_p(x) = u1(x) e^(4x) + u2(x) e^(x)\)

where u1(x) and u2(x) are functions to be determined.

First derivative of  y_p(x) '

\(y_p'(x) = u1'(x) e^(4x) + 4u1(x) e^(4x) + u2'(x) e^(x) + u2(x) e^(x)\)

Second derivative of  y_p(x) '

\(y_p''(x) = u1''(x) e^(4x) + 8u1'(x) e^(4x) + 16u1(x) e^(4x) + u2''(x) e^(x) + 2u2'(x) e^(x) + u2(x) e^(x)\)

When this y_p(x), y_p'(x), and y_p''(x) is inputed into the nonhomogeneous equation, we have

\(u1''(x) e^(4x) + 8u1'(x) e^(4x) + 16u1(x) e^(4x) + u2''(x) e^(x) + 2u2'(x) e^(x) + u2(x) e^(x) - 5[u1'(x) e^(4x) + 4u1(x) e^(4x) + u2'(x) e^(x) + u2(x) e^(x)] + 4[u1(x) e^(4x) + u2(x) e^(x)] \\= e^(3x)u1''(x) e^(4x) + 4u1'(x) e^(4x) + u2''(x) e^(x) + 2u2'(x) e^(x) = e^(3x)\)

\(u1''(x) + 4u1'(x) = 0\\u2''(x) + 2u2'(x) = e^(3x)\)

The solutions of the above equations are ;

\(u1'(x) = c1 e^(-4x)\\u2'(x) = (1/2) e^(3x)\)

Integrating u1'(x) with respect to x,

\(u1(x) = (-1/4) c1 e^(-4x) + c2\\u2(x) = (1/6) e^(3x) + c3\)

N.B: c1,c2,c3 are arbitrary constants of integration.

The solution of the nonhomogeneous equation is given as;

\(y_p(x) = (-1/4) c1 e^(-x) e^(4x) + (1/6) e^(3x) e^(x)\\y_p(x) = (-1/4) c1 e^(3x) + (1/6) e^(4x)\\y(x) = y_h(x) + y_p(x)\)

By substituting \(y_h(x)\)and \(y_p(x)\) into the above equation, we have

\(y(x) = c1 e^(4x) + c2 e^(x) - (1/4) c1 e^(3x) + (1/6) e^(4x)\\y(x) = c1 e^(4x) - (1/4) c1 e^(3x) + c2 e^(x) + (1/6) e^(4x)\)

Thus, the general solution of the non homogeneous equation \(y" - 5y' + 4y = e^(3x) is y(x) = c1 e^(4x) - (1/4) c1 e^(3x) + c2 e^(x) + (1/6) e^(4x)\), where c1, c2 are arbitrary constants of integration.

There are 28 ways to choose 6 teams for the playoffs if there are 8 college basketball teams in a certain sub-division.

To determine the number of ways to choose 6 teams for the playoffs out of the 8 college basketball teams in a certain Sub-Division, we can use the combination formula. The formula for combinations is given by

nCr = n! / (r! * (n-r)!),

where n represents the total number of teams and r represents the number of teams to be chosen.

In this case, n = 8 and r = 6.

Plugging in these values, we have

8C6 = 8! / (6! * (8-6)!) = 8! / (6! * 2!) = (8 * 7) / (2 * 1) = 28.

a) Approximately 79.38% of the phones have a battery life of at least 4 hours and 45 minutes.

b) Approximately 34.13% of the phones have a battery life between 4.5 hours and 5.25 hours.

c) Approximately 50% of the phones have a battery life less than 5 hours or greater than 5.5 hours.

a) What percentage battery life of 4 hours and 45 minutes?

a) For phones with a mean battery life of 5 hours and a standard deviation of 15 minutes, we can calculate the percentage of phones with a battery life of at least 4 hours and 45 minutes. By converting 4 hours and 45 minutes to minutes (4*60 + 45 = 285 minutes) and using the z-score formula, we find that the z-score is (285 - 300) / 15 = -1. Hence, the percentage is approximately 1 - 0.8359 = 0.1641, which is about 16.41%.

b) What percentage battery life between 4.5 hours and 5.25 hours?

b) To determine the percentage of phones with a battery life between 4.5 hours and 5.25 hours, we need to calculate the z-scores for both values. Converting the hours to minutes, we have 4.5 hours = 270 minutes and 5.25 hours = 315 minutes. The z-scores are (270 - 300) / 15 = -2 and (315 - 300) / 15 = 1. By referring to the standard normal distribution table, we find that the area between -2 and 1 is approximately 0.6141. Thus, the percentage is 0.6141 * 100 = 61.41%.

c) For the percentage of phones with a battery life less than 5 hours or greater than 5.5 hours, we need to calculate the z-score for both cases. The z-score for 5 hours is (300 - 300) / 15 = 0, and the z-score for 5.5 hours is (330 - 300) / 15 = 2. By referring to the standard normal distribution table, we find that the area to the left of 0 is 0.5 and the area to the right of 2 is 1 - 0.9772 = 0.0228. Adding these percentages, we get 0.5 + 0.0228 = 0.5228, which is approximately 52.28%.

What is a parallelogram?

A parallelogram is the name given to a quadrilateral in geometry. In a parallelogram, the opposing sides are parallel and of equal length. The rhombus, rectangle, and square are just a few shapes that are parallelograms.

Having two sets of parallel sides makes a quadrilateral a parallelogram. A parallelogram has opposite sides that are the same length and angles that are the same size. Additionally, the internal angles on the same transverse side are supplementary. 360 degrees are equal to the total of all internal angles.

If both pairs of opposite sides of a quadrilateral are congruent , then the quadrilateral is a parallelogram.

Bri           3                       24 oz

Angela    4                        32 oz

Start by checking if the table has a constant rate

Constant rate = Smoothie Size/Mango Used

Constant rate = 8/1 = 8

Constant rate = 24/3 = 8

Constant rate = 32/4 = 8

Answer: g = -0.32

Step-by-step explanation:

Given

6 (-2g - 1) = (13g + 2)

Expand parentheses and apply the distributive property

6 · (-2g) - 6 · 1 = 13g + 2

-12g - 6 = 13g + 2

Add 12g on both sides

-12g - 6 + 12g = 13g + 2 + 12g

-6 = 25g + 2

Subtract 2 on both sides

-6 - 2 = 25g + 2 - 2

-8 = 25g

Divide 25 on both sides

-8 / 25= 25g / 25
