The equation of the sphere that passes through the point (4, 3, -1) and has a center at (3, 8, 1) is: (x - 3)^2 + (y - 8)^2 + (z - 1)^2 = 30.

To find the equation of the sphere passing through the point (4, 3, -1) with a center at (3, 8, 1), we can use the general equation of a sphere:

(x - h)^2 + (y - k)^2 + (z - l)^2 = r^2

where (h, k, l) represents the center of the sphere and r represents the radius.

First, we need to find the radius. The distance between the center and the given point can be calculated using the distance formula:

√[(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2]

Substituting the coordinates of the center (3, 8, 1) and the given point (4, 3, -1), we have:

√[(4 - 3)^2 + (3 - 8)^2 + (-1 - 1)^2]

Simplifying, we get:

√[1 + 25 + 4] = √30

Therefore, the radius of the sphere is √30.

Now we can substitute the center (3, 8, 1) and the radius √30 into the general equation:

(x - 3)^2 + (y - 8)^2 + (z - 1)^2 = 30

So, the equation of the sphere that passes through the point (4, 3, -1) and has a center at (3, 8, 1) is:

(x - 3)^2 + (y - 8)^2 + (z - 1)^2 = 30.

This equation represents all the points on the sphere's surface.

The z-score for an observation of 200 is approximately -2.000.

Here are the steps to calculate the z-score for an observation of 200 based on a normal distribution with a mean of 500 and a standard deviation of 150:

        x - μ = 200 - 500 = -300

        -300 / 150 = -2

        -2 ≈ -2.000

So, the z-score for an observation of 200 is approximately -2.000.

A z-score is a measure of how many standard deviations a given value is from the mean of a dataset. It is calculated by subtracting the mean of the dataset from a given value and dividing the result by the standard deviation of the dataset.

In the case of a normal distribution with a mean of 500 and a standard deviation of 150, a z-score of -2 would indicate that an observation of 200 is 2 standard deviations below the mean. This information can be used to determine the proportion of data within the dataset that is above or below a certain value, or to make comparisons between different datasets.

The two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

Independent events are those events whose occurrences do not depend on the other events.

A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested.

Consider the following events:

The probability of event A is,

\(P(A)=\dfrac{83}{240}\)

The probability of event B is,

\(P(B)=\dfrac{80}{240}=\dfrac{1}{3}\)

The probability of event C is,

\(P(C)=\dfrac{45}{240}=\dfrac{3}{16}\)

The probability of event D is,

\(P(A)=\dfrac{72}{240}=\dfrac{3}{10}\)

If the probability of an event is calculated given that the other is happened, only the probability of event B and D we get such that,

\(P(B\cap D)=P(B).P(D)\\\dfrac{24}{240}=\dfrac{1}{3}\times \dfrac{3}{10}\\\dfrac{1}{10}=\dfrac{1}{10}\)

Answer:

The coordinates of G' are \(G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)\).

Step-by-step explanation:

From Linear Algebra, we define the dilation of point G by the following expression:

\(G'(x,y) = O(x,y) + k\cdot [G(x,y)-O(x,y)]\) (1)

Where:

\(O(x,y)\) - Center of dilation, dimensionless.

\(k\) - Scale factor, dimensionless.

\(G(x,y)\) - Coordinates of point G, dimensionless.

\(G'(x,y)\) - Coordinates of point G', dimensionless.

If we know that \(O(x,y) = (0,0)\), \(k = \frac{1}{3}\), \(G(x,y) = (-2,4)\), then the point G' is:

\(G'(x,y) = (0,0) + \frac{1}{3}\cdot [(-2,4)-(0,0)]\)

\(G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)\)

The coordinates of G' are \(G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)\).

If the triangles ΔABC≅ΔDEF then the congruent to side BA is ED.

The dimensions of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size and shape are determined by its three sides and three angles, respectively. If pairs of corresponding sides and corresponding angles are equal, two triangles are said to be congruent. They are the exact same size and form. Triangles can satisfy a wide variety of congruence requirements.

From the ΔABC ≅ ΔDEF we observe that the corresponding segment to BA in triangle DEF is ED.

A 40 gram sample of a substance that’s used for drug research has a k-value of 0.1472. The substance's half-life, in days, is approximately 4.7 days.

The half-life of a substance is the time it takes for half of the substance to decay or undergo a transformation. The half-life can be determined using the formula:

t = (0.693 / k)

where t is the half-life and k is the decay constant.

In this case, we are given that the sample has a k-value of 0.1472. We can use this value to calculate the half-life.

t = (0.693 / 0.1472) ≈ 4.7 days

In order to calculate the difference p^D - p^E, we need to have the actual values or expressions for p^D and p^E.

The symbol ^ typically represents a statistical estimator, which is an estimate of a population parameter based on a sample. The difference between two estimators would depend on the specific context and the calculations used to obtain those estimators.

For example, if p^D represents the proportion of successes in a sample D and p^E represents the proportion of successes in a sample E, we would need to have the sample data or additional information about the samples in order to calculate their difference.

Similarly, if p^D and p^E represent the means or any other statistical measures, we would need the actual values or equations to perform the subtraction and find their difference.

Without further information, it is not possible to determine the value of the difference p^D - p^E.

It will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

To find the number of days it will take for $9500 to earn $800 at an annual interest rate of 8.25%, we need to use the formula for simple interest:

Interest = Principal * Rate * Time

In this case, we are given the interest ($800), the principal ($9500), and the annual interest rate (8.25%). We need to solve for time.

Let's denote the time in years as "t". Since we're looking for the number of days, we'll convert the time to a fraction of a year by dividing by 365 (assuming a standard 365-day year).

$800 = $9500 * 0.0825 * (t / 365)

Simplifying the equation:

800 = 9500 * 0.0825 * (t / 365)

Divide both sides by (9500 * 0.0825):

800 / (9500 * 0.0825) = t / 365

Simplify the left side:

800 / (9500 * 0.0825) ≈ 0.1083

Now, solve for t by multiplying both sides by 365:

0.1083 * 365 ≈ t

t ≈ 39.532

Therefore, it will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

To multiply these numbers, we multiply the decimal numbers and add the exponents:

(1.2588 × \(10^3\)) × (1.06 × \(10^-^2\)) = 1.333128 × \(10^1\)

Since the original numbers have five significant figures, we round the final answer to five significant figures:

1.3331 × \(10^1\)

(d) \((1.11)^(^1^/^2^)\)

To calculate the square root, we raise the number to the power of 1/2:

\((1.11)^(^1^/^2^)\)= 1.0524
