After 18.8 years, Halle account exceed $10,000 if Halle deposited $4000 into an account that earns 5% interest, each year.

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \(\rm y = a^x\)

where a is a constant and a>1

We have an exponential equation:

\(\rm a = 4000(1+ 0.05)^t\)

Plug a = $10,000

\(\rm 10000 = 4000(1+ 0.05)^t\)

After calculating:

\(\rm 1.05^t= 2.5\)

t = 18.78 ≈ 18.8 years

Thus, after 18.8 years, Halle account exceed $10,000 if Halle deposited $4000 into an account that earns 5% interest each year.

We need a sample size of at least 665 drivers to estimate the proportion of all drivers exceeding the legal speed limit on the certain stretch of road between Los Angeles and Bakersfield with a margin of error of 0.04 and a 99% confidence level.

To estimate the proportion of all drivers exceeding the legal speed limit on a certain stretch of road between Los Angeles and Bakersfield with a margin of error of 0.04 and a 99% confidence level, we need to use the following formula:

\(n = (Z^2 * p * (1 - p)) / E^2\)

where n is the sample size, Z is the Z-score for the desired confidence level (2.576 for 99% confidence level), p is the estimated proportion of drivers exceeding the speed limit (we don't have an estimate, so we'll use 0.5 for maximum variability), and E is the margin of error we want (0.04).

Plugging in the values, we get:

\(n = (2.576^2 * 0.5 * (1 - 0.5)) / 0.04^2\)

n = 664.92

Therefore, we need a sample size of at least 665 drivers to estimate the proportion of all drivers exceeding the legal speed limit on the certain stretch of road between Los Angeles and Bakersfield with a margin of error of 0.04 and a 99% confidence level.

Hello there. To solve this question, we'll have to remember some properties about foci and asymptotes of hyperbolas.

First, the equation for a hyperbola with real axis a and imaginary axis b is:

centered at (x0, y0) and axis of symmetry being the x-axis.

The asymptotes are given by the equations:

The relationship between a, b (the real and imaginary axis) and the value c (that stands for the coordinates of the foci)

for hyperbolas is:

From the equation of the asymptotes, we find that:

Hence we get:

And from the coordinates of the foci, we get

Hence

Then from the relation with b, we get

Finally, the center is the midpoint between the foci. In this case, we get:

So we say the center is at the origin, or (x0, y0) = (0, 0).

Using fraction, the total number of cupcakes is obtained to be 5.

What is fraction?

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

If 4 cupcakes represent 80% of the order, then we can use proportional reasoning to find the total number of cupcakes.

Specifically, if x is the total number of cupcakes, then we can write -

4/x = 80/100

where the left-hand side represents the fraction of the order that is Nom-Nom-Nom cupcakes, and the right-hand side represents the percentage of the order that is Nom-Nom-Nom cupcakes.

Solving for x, we get -

x = 4 / (80/100) = 5

So the total number of cupcakes is 5. Since 4 of them are Nom-Nom-Nom cupcakes, the remaining 1 cupcake must be a Wow cupcake.

Therefore, in total there are 5 cupcakes.

We can express f(x) as a sum of partial fractions as:  f(x) = (-10 / (x + 6)) + (78 / (x - 4))

To write the function f(x) = \((68x + 168) / (x^2 + 2x - 24)\) as a sum of partial fractions, we first need to factor the denominator:

\(x^2 + 2x - 24 = (x + 6)(x - 4)\)

So we can write:

f(x) = (68x + 168) / ((x + 6)(x - 4))

Now we can use the method of partial fractions to express f(x) as a sum of simpler fractions:

f(x) = A / (x + 6) + B / (x - 4)

where A and B are constants that we need to find. To do this, we can multiply both sides of the equation by the common denominator (x + 6)(x - 4):

(68x + 168) = A(x - 4) + B(x + 6)

Expanding and collecting like terms, we get:

68x + 168 = (A + B) x + (6B - 4A)

Since this equation holds for all values of x, we can equate the coefficients of x and the constant terms separately:

68 = A + B

168 = 6B - 4A

Solving these two equations simultaneously, we get:

A = -10

B = 78

Therefore, we can express f(x) as a sum of partial fractions as:

f(x) = (-10 / (x + 6)) + (78 / (x - 4))

Answer:

17/2 units^3

Explanation:

The volume of the rectangular prism is given by

Volume = width * height* length

Now we are already given that

width * height = 2 1/8 units

Therefore, our equation for volume becomes

Volume = 2 1/ 8* length

since length = 4 units, we have

Volume = 2 1/8 * 4

Volume = 17 /2 units

Answer: Solution = (- 3, 2)

Explanation:

The system of equations is

6x + 8y = -2

-5x - 7y = 1

We would eliminate x. The first step is to multiply equation 1 by 5 and equation 2 by 6. We have

30x + 40y = - 10

- 30x - 42y = 6

By adding both equations, we have

30x + - 30x + 40y + - 42y = - 10 + 6

30x - 30x + 40y - 42y = - 4

- 2y = - 4

Dividing both sides by - 2,

- 2y/- 2 = - 4/- 2

y = 2

Substitu4ing y = 2 into equation 1, we hav

6x + 8 * 2 = -2

6x + 16 = - 2

Subtracting 16 from bth sides,

6x + 16 - 16 = - 2 - 16

6x = - 18

Dividing both sides by 6,

6x/6 = - 18/6

x = - 3

Solution = (- 3, 2)

The matrix equation that could show the total books is \(\left[\begin{array}{cc}7&1\\2&6\end{array}\right] + \left[\begin{array}{cc}4&3\\6&1\end{array}\right] = \left[\begin{array}{cc}11&4\\8&7\end{array}\right]\)

The given parameters are the two-way tables attached to the question.

From the tables, we have the following matrices

\(June = \left[\begin{array}{cc}7&1\\2&6\end{array}\right]\)

\(July = \left[\begin{array}{cc}4&3\\6&1\end{array}\right]\)

The sum of these matrices is represented as:

June + July =  Total

So, we have:

\(\left[\begin{array}{cc}7&1\\2&6\end{array}\right] + \left[\begin{array}{cc}4&3\\6&1\end{array}\right]\)

Add the elements at corresponding positions

Answer:

To create a line plot for this data, we can first convert all the fractions to a common denominator, such as eighths:

Monday: 6/8 of an hour

Wednesday: 4/8 of an hour

Friday: 2/8 of an hour

Sunday: 4/8 of an hour

Then, we can draw a number line with tick marks representing each day of the week and plot a dot for each amount of time spent working out:

0         1         2         3         4

|---------|---------|---------|---------|   <- Number line

         .     .

       .             .

   .                     .

.                             .

To find out how much time June should work out each day to spend an even amount of time working out, we can first find the total amount of time she spent working out:

6/8 + 4/8 + 2/8 + 4/8 = 16/8 = 2 hours

Since there are four days she worked out, to find out how much time she should work out each day, we can divide the total time by four:

2 hours ÷ 4 = 0.5 hours

Therefore, June should work out for 0.5 hours, or 30 minutes, each day to spend an even amount of time working out.

The probability that the child spends less than 1 hour per day unsupervised is approximately 0.1335.

To find the probability that the child spends less than 1 hour per day unsupervised, we can use the normal distribution and the given mean and standard deviation.

Given:
Mean (μ) = 3 hours
Standard Deviation (σ) = 1.8 hours

We want to find the probability that the child spends less than 1 hour per day unsupervised, which is equivalent to finding the area under the normal distribution curve to the left of 1 hour.

Using the Z-score formula:
Z = (x - μ) / σ

Substituting the values:
Z = (1 - 3) / 1.8
Z = -1.11

Now, we can use a Z-table or a calculator to find the probability associated with the Z-score of -1.11. The probability can be found as the area to the left of the Z-score.

Looking up the Z-score of -1.11 in the Z-table, we find the corresponding probability to be 0.1335.

So, the probability that the child spends less than 1 hour per day unsupervised is approximately 0.1335.

The probability statement is: p(x < 1) = 0.1335.
