If a confidence interval for a difference in proportions (p1-p2) is (-6%, 12%), the correct conclusion is that we are not sure which of p1 or p2 is larger.

The confidence interval includes both positive and negative values, indicating that the difference could be positive (p1 is larger than p2), negative (p1 is smaller than p2), or even zero (p1 is equal to p2). Therefore, based on the given confidence interval, we cannot make a definitive claim about the relative sizes of p1 and p2.

Using the Riemann sum, we divide the interval [2, 4] into n equal subintervals, where Δx = (4 - 2) / n.

To find the expression for the area under the graph of the function f(x) = x^2 √(1/2x) as a limit, we can use the definition of a Riemann sum and take the limit as n approaches infinity of the sum from i = 1 to n.

The Riemann sum is a method to approximate the area under a curve by dividing it into smaller rectangular regions. In this case, we need to express the area under the graph of f(x) as a limit of a Riemann sum.

The expression for the area under the graph of f(x) as a limit is given by:

lim n → ∞ Σ i=1^n [f(xi) Δx]

In this formula, xi represents the ith subinterval, Δx represents the width of each subinterval, and f(xi) represents the value of the function at a point within the ith subinterval.

To calculate the Riemann sum, we divide the interval [2, 4] into n equal subintervals, where Δx = (4 - 2) / n. Then, for each subinterval, we evaluate f(xi) and multiply it by Δx. Finally, we sum up all these values as n approaches infinity.

However, without evaluating the limit or specifying the specific method of partitioning the interval, it is not possible to provide a more precise expression for the area. The given information is insufficient to calculate the exact value.

The implicit general solution is:
x - 1 = -5/(5(1-y)^5)

The explicit solution for the initial value problem y(0) = 0 is:

y = 1 - ((x - 1)^(-1/5)).

To find the explicit solution for the initial value problem y(0) = 0 for the first-order separable equation y' = ((1-y)^6)/5, follow these steps:

Step 1: Separate variables
Rearrange the equation to separate the variables, y and x:
(dy/dx) = ((1-y)^6)/5
5 dy/((1-y)^6) = dx

Step 2: Integrate both sides
Integrate both sides with respect to their respective variables:
∫ 5 dy/((1-y)^6) = ∫ dx

Step 3: Evaluate the integrals
Evaluate both integrals:
-5/5(1-y)^5 = x + C1

Step 4: Solve for the constant, C1, using the initial condition y(0) = 0:
-5/5(1-0)^5 = 0 + C1
C1 = -1

Step 5: Write the implicit general solution:
x - 1 = -5/(5(1-y)^5)

Step 6: Solve for y to find the explicit solution:
(1-y)^5 = -1/(x - 1)
1 - y = ((x - 1)^(-1/5))
y = 1 - ((x - 1)^(-1/5))

The explicit solution for the initial value problem y(0) = 0 is y = 1 - ((x - 1)^(-1/5)).

Answer:

(4,4)

Step-by-step explanation:

The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.

x^2 - 6x + 12 = 2x - 4

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x = 4

Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.

y = 2x - 4 = 2(4) - 4 = 4

Therefore, the solution of this system of equations is (4, 4).

Therefore, the correct answer is (4, 4).

The expected value is the long-term average outcome of a random variable. It is calculated by multiplying each possible outcome by its probability and summing them up. In simpler terms, it represents the average value we expect to get over many trials.

The expected value is a concept in probability and statistics that represents the long-term average outcome of a random variable. It is also known as the mean or average. To calculate the expected value, we multiply each possible outcome by its probability and sum them up.

For example, let's say we have a fair six-sided die. The possible outcomes are numbers 1 to 6, each with a probability of 1/6. To find the expected value, we multiply each outcome by its probability:

Summing up these values gives us:

1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6 = 21/6 = 3.5

Therefore, the expected value of rolling a fair six-sided die is 3.5. This means that if we roll the die many times, the average outcome will be close to 3.5.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The commutative property of addition can be used to change the order of the addends.

The associative property of addition can be used to change the grouping of the addends.

We can regroup the addends in a way that makes the addition easier. For example, we can group the like terms together as follows:

(7 + 1) + (4 + 2 + 3 + 4 + 2 + 2) + (3 + 3 + 1 + 1) + (4 + 2 + 2 + 1) + (7 + 1)

This regrouping makes it easier to add the like terms together, since we can add the terms within each parentheses first, and then add the resulting sums together. For example, we have:

8 + 17 + 8 + 9 + 8

This simplifies to:

50

A gallon's volume is about equivalent to 3.78541 litres. Thus, a gallon is more than three liters.

4 quarts, 8 pints, or 128 fluid ounces make up a gallon. For instance, it's simple to convert between litres and gallons by remembering that a quart is slightly smaller than a litre and that 4 litres is little larger than 1 gallon. To be precise, 1 litre is equal to 0.264 gallon (just over a quart), and 4 litres are equal to 1.06 gallons. For example, 0.26 gallons is around 1 litre of water. Hence, if you were to fill a half-gallon water container with one litre of water, the bottle would be filled to about halfway. The volume of a gallon is about equal to 3.78541 liters. A gallon is therefore larger than 3 litres.

It's important to remember that using the binomial approximation assumes a large population size, which may not be the case here.

To answer your questions, we will use R commands to calculate the probabilities.

(a) To find the probability that exactly 6 of the students will be full-time, we can use the "dhyper" function in R. The parameters are x = 6, m = 30 (number of full-time students), n = 20 (number of part-time students), and k = 10 (sample size).

R command:
```R
dhyper(x = 6, m = 30, n = 20, k = 10)
```

(b) To find the probability that at most 8 of the students will be full-time, we can use the "phyper" function in R, which calculates the cumulative probability. We need to calculate P(X ≤ 8).

R command:
```R
phyper(q = 8, m = 30, n = 20, k = 10)
```

(c) To use the binomial approximation, we can use the "dbinom" function in R with p = 0.6 (probability of full-time student) and n = 10 (sample size). We want to calculate P(X = 6).

R command:
```R
dbinom(x = 6, size = 10, prob = 0.6)
```

Compare this result with the answer in part (a). If the difference is relatively small, it's appropriate to use the binomial approximation in this scenario.

Add 1 to both sides.

-2(-2x + 3) - x = -27

Use distributive property

-2 · (-2x) = 4x

-2 · 3 = -6

Your equation should look like this now:

4x - 6 - x = -27

Add 6 to both sides

4x - x = -21

Subtract x from 4x

3x = -21

Divide both sides by 3

To evaluate the given integrals, we can use the properties of definite integrals and the given information. The integral ∫₀⁷ f(x) dx can be evaluated by splitting it into two parts: ∫₀⁵ f(x) dx and ∫₅⁷ f(x) dx.

Given: ∫₀⁵ f(x) dx = 13 and ∫₅⁷ f(x) dx = 6

a) To evaluate ∫₀⁷ f(x) dx, we split it into two parts:

∫₀⁵ f(x) dx + ∫₅⁷ f(x) dx

Using the given information, we substitute the known values:

∫₀⁷ f(x) dx = ∫₀⁵ f(x) dx + ∫₅⁷ f(x) dx

∫₀⁷ f(x) dx = 13 + 6

∫₀⁷ f(x) dx = 19

b) To evaluate ∫₀⁵ f(x) dx, we already know that ∫₀⁵ f(x) dx = 13.

c) To evaluate ∫₅⁵ f(x) dx, we can observe that the interval is from 5 to 5, which means there is no interval or area under the curve. Therefore, ∫₅⁵ f(x) dx = 0.

d) To evaluate ∫₀⁵ 2f(x) dx, we can use the property of scaling. Since we multiply the integrand by 2, the integral also gets multiplied by 2:

∫₀⁵ 2f(x) dx = 2 * ∫₀⁵ f(x) dx

Using the given information, we substitute the known value:

∫₀⁵ 2f(x) dx = 2 * 13

∫₀⁵ 2f(x) dx = 26

Therefore, the values of the given integrals are:

a) ∫₀⁷ f(x) dx = 19

b) ∫₀⁵ f(x) dx = 13

c) ∫₅⁵ f(x) dx = 0

d) ∫₀⁵ 2f(x) dx = 26
