Answer:

\( \sf \: 6 + 3b + 8 = 32\)

Step-by-step explanation:

Given expression,

→ 6 + 3b + 8

Now we have to use,

→ b = 6

Let's solve the expression,

→ 6 + 3b + 8

→ 6 + 3(6) + 8

→ 6 + 18 + 8

→ 24 + 8

→ 32 => final value

Hence, the answer is 32.

(a) `dy/dx = (2y - 2x)/(3y - 2x)`.

(b) The slope of the tangent line at points where x = 6 is 0.

(c) the curve has a vertical tangent line when x = (3/2)y.

(a) To show that `dy/dx = (2y - 2x)/(3y - 2x)`, we need to find the derivative of `y` with respect to `x`. We can do this by implicitly differentiating the given equation.

Differentiating both sides of the equation with respect to `x`, we get:

4x(dx/dx) + 6y(dy/dx) - 4[(dx/dx)y + x(dy/dx)] = 0

Simplifying the equation, we have:

4x + 6y(dy/dx) - 4xy - 4xy - 4x(dy/dx) = 0

Rearranging the terms and combining like terms, we get:

(6y - 4x)(dy/dx) = 8x - 8xy

Dividing both sides by (6y - 4x), we obtain:

dy/dx = (8x - 8xy)/(6y - 4x)

Simplifying further, we have:

dy/dx = (2x(4 - 4y))/(2(3y - 2x))

Canceling out the common factors, we get:

dy/dx = (2y - 2x)/(3y - 2x)

Therefore, `dy/dx = (2y - 2x)/(3y - 2x)`.

(b) To find the slope of the tangent line at the points where x = 6, substitute x = 6 into the expression we found for `dy/dx` in part (a):

dy/dx = (2(6) - 2(6))/(3y - 2(6))

      = 0/(3y - 12)

      = 0

The slope of the tangent line at points where x = 6 is 0.

(c) To find the value of x at which the curve has a vertical tangent line, we need to find the point(s) where the slope `dy/dx` is undefined. In other words, we need to find the values of x where the denominator of `dy/dx` becomes zero.

Setting the denominator equal to zero and solving for x:

3y - 2x = 0

2x = 3y

x = (3/2)y

So, the curve has a vertical tangent line when x = (3/2)y.

I hope this helps

a) The rate of people leaving the health club, L(t), can be calculated as:

L(11) = 0.013(11)^2 - 0.25(11) + 8

b) To find the number of people, we integrate the net rate of change over the time interval:

Number of People at t=20 = Integral of (E(t) - L(t)) dt, from t=0 to t=20

c) This can be done by finding the critical points of the net rate of change and evaluating them to determine whether they correspond to maximum or minimum values.

To determine whether the number of people in the facility is increasing or decreasing at time t=11, we need to compare the rates of people entering and leaving the health club at that time.

a) At time t=11 hours:

The rate of people entering the health club, E(t), can be calculated as:

E(11) = -0.018(11)^2 + 11

Similarly, the rate of people leaving the health club, L(t), can be calculated as:

L(11) = 0.013(11)^2 - 0.25(11) + 8

By comparing the rates of people entering and leaving, we can determine if the number of people in the facility is increasing or decreasing. If E(t) is greater than L(t), the number of people is increasing; otherwise, it is decreasing.

b) To find the number of people in the health club at time t=20, we need to integrate the net rate of change of people over the time interval 0≤t≤20 hours.

The net rate of change of people can be calculated as:

Net Rate = E(t) - L(t)

To find the number of people, we integrate the net rate of change over the time interval:

Number of People at t=20 = Integral of (E(t) - L(t)) dt, from t=0 to t=20

c) To determine the time t at which the number of people in the health club is a maximum, we need to find the maximum value of the number of people over the interval 0≤t≤20.

This can be done by finding the critical points of the net rate of change and evaluating them to determine whether they correspond to maximum or minimum values.

Let's calculate these values and solve the problem.

Note: Since the calculations involve a series of mathematical steps, it would be best to perform them offline or using appropriate computational tools.

The area to the right of z = -1.15 is 1 - 0.6251, or 0.3749

The area under the standard normal curve to the right of z = -1.81 and z = -1.15The normal distribution is one of the most widely utilized statistical distributions in the real world. It's a bell-shaped curve that's symmetrical around the mean. The mean and the standard deviation, which measures the variability of the data, are the two fundamental parameters of a normal distribution. The standard normal curve, or z-distribution, is a special form of the normal distribution that has a mean of zero and a standard deviation of one. The majority of normal distribution calculations are converted to z-score values. To find the area under the standard normal curve to the right of z = -1.81 and z = -1.15, follow these steps:Step 1: Draw the standard normal curve with a mean of zero and a standard deviation of one, and label the points z = -1.81 and z = -1.15 on it.Step 2: Determine the standard normal curve's total area to the left of z = -1.81 and z = -1.15, since the area under the standard normal curve to the right of z = -1.81 and z = -1.15 is the same as the area to the left of z = 1.81 and z = 1.15. Use a standard normal distribution table or calculator to locate the area. The table gives a value of 0.0352 for z = -1.81 and 0.1251 for z = -1.15. The total area to the left of z = -1.81 is therefore 0.0352 + 0.5000, or 0.5352. The total area to the left of z = -1.15 is 0.1251 + 0.5000, or 0.6251.Step 3: Determine the area to the right of z = -1.81 and z = -1.15 by subtracting the total area to the left of z = -1.81 and z = -1.15 from 1. The area to the right of z = -1.81 is 1 - 0.5352, or 0.4648. The area to the right of z = -1.15 is 1 - 0.6251, or 0.3749.

The probability of not drawing a queen from a standard deck of 52 cards is 12/13

In a standard deck of 52 cards, we have

Total number of cards = 52

Queen cards = 4

The probability of not drawing a queen from a standard deck of 52 cards is calculated as

P = 1 - P(Queen)

Where

P(Queen) = Queen cards/Total number of cards

So, we have

P(Queen) = 4/52

Substitute P(Queen) = 4/52 in the equation P = 1 - P(Queen)

This gives

P = 1 - 4/52

Evaluate the difference

P = 48/52

Simplify

P = 12/13

Hence, the probability of not drawing a queen from a standard deck of 52 cards is 12/13

The table layout and relationship structure of a relational database is called its schema.

A schema in a relational database refers to the overall structure and organization of tables, their attributes (columns), and the relationships between them. It defines the blueprint for how the data is organized and stored in the database.

The schema includes information such as the table names, column names, data types, constraints, and the relationships established through keys (such as primary keys and foreign keys). It provides a logical representation of the database structure and helps ensure data integrity and consistency.

The schema serves as a guide for creating, modifying, and querying the database tables. It defines the structure that enforces rules and relationships between tables, facilitating data manipulation and retrieval.

By designing a well-defined schema, database administrators and developers can establish the foundation for efficient data storage, retrieval, and management within a relational database system.

Answer:

11.66 meters

Step-by-step explanation:

First draw a diagram. See attachment.

We notice that if we draw everything out, we get a right triangle.

The flag pole and its shadow are the two legs, with lengths 10 and 6 meters. We want to find the distance from the top of the pole to the end of the shadow, so we need to use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, a = 10 and b = 6, and we want to find c:

a² + b² = c²

10² + 6² = c²

100 + 36 = c²

136 = c²

c = √136 = 2√34 ≈ 11.66 meters

Answer:

11.7

Step-by-step explanation:

To find the union and intersection of the intervals I₁ = (-2, 2] and I₂ = [1, 5), let’s consider the overlapping values and the combined range.

The union of two intervals includes all the values that belong to either interval. Taking the union of I₁ and I₂, we have:

I₁ U I₂ = (-2, 2] U [1, 5)

To find the union, we combine the intervals while considering their overlapping points:

I₁ U I₂ = (-2, 2] U [1, 5)
= (-2, 2] U [1, 5)

So the union of the intervals I₁ and I₂ is (-2, 2] U [1, 5).

Now let’s find the intersection of the intervals I₁ and I₂, which includes the values that are common to both intervals:

I₁ ∩ I₂ = (-2, 2] ∩ [1, 5)

To find the intersection, we consider the overlapping range between the two intervals:

I₁ ∩ I₂ = [1, 2]

Therefore, the intersection of the intervals I₁ and I₂ is [1, 2].

The first thing to do is calculate the dimensions of the pizza box. Based on our data, we know 256 = s2. Solving for s (by taking the square root of both sides), we get 16 = s (or s = 16).

Now, we know that the diameter of the pizza is four inches less than 16 inches. That is, it is 12 inches. Be careful! The area of the circle is given in terms of radius, which is half the diameter, or 6 inches. Therefore, the area of the pizza is π * 62 = 36π in2. If the pizza is 8-slices, one slice is equal to 1/8 of the total pizza or (36π)/8 = 4.5π in2.

Assuming Alice has 2 apples, there are 19 ways to split the rest of the apples with Becky and Chris.

The total number of ways to split 24 apples between the three friends is equal to 19 + 18 + 17 + 16 + 15 + ...……+ 2 + 1 = 20 x ( 19 / 2 ) = 190

Alice can share them with Becky and Chris in a variety of ways, as long as each person has at least 2 apples. For example, Alice could give Becky 8 apples and Chris 16 apples, or she could give Becky 10 apples and Chris 14 apples. As long as each person has at least 2 apples, there are many ways for Alice to share her apples.To split the apples, we employ the Ball-and-urn method, also referred to as "Sticks and Stones" or "Stars and Bars."

the correct decimal answer is 196.54

Okay, here are the steps:

1) For the new drug group, the mean reduction is 25 points and standard deviation is 3.1.

To get the 90% CI, we calculate:

Mean ± (1.645 * SD)

= 25 ± (1.645 * 3.1)

= 24.584 to 25.416

2) For the placebo group, the mean reduction is 18 points and standard deviation is 2.8.

To get the 90% CI, we calculate:

Mean ± (1.645 * SD)

= 18 ± (1.645 * 2.8)

= 17.624 to 18.376

3) Since the CI for the new drug (24.584 to 25.416) lies above the CI for the placebo (17.624 to 18.376), there is evidence that the drug is working.

The other options are incorrect. The CI for the new drug does not lie below the placebo CI, so there is evidence the drug is working, not not working.

Thekey is to compare the CI ranges for the two groups. If the CI range for the new drug group lies above the CI range for the placebo group, that indicates the new drug is likely more effective in reducing blood sugar levels, providing evidence that the drug is working.
