The probability that they have an average weight of greater than 10 pounds and less than 15 pounds is 0.84134

In this question we have been given there are 250 dogs at a dog show who weigh an average of 15 pounds, with a standard deviation of 6 pounds. of 10 dogs are chosen at random.

We need to find the probability that they have an average weight of greater than 10 pounds and less than 15 pounds.

Given, μ = 12, σ = 8, n = 4

P(X > 8)

= P(z > (8 - 12 / 8/√4))

= P(z > -1)

= 1 - P(z ≤ -1)

= 1 - [1 - P(z ≤ 1)]

=  P(z ≤ 1)

= 0.84134

Therefore, the required probability is 0.84134

The correlation coefficients are expressed on a standard scale that always ranges from -1.00 up to +1.00.

Correlation does not mean equal causation. Just because two variables have a relationship does not necessarily mean that changes in one variable cause changes in the other. Correlations indicate that there is a relationship between variables, but this does not necessarily determine that one variable causes the other to change.

Correlations range from -1.00 to +1.00. The correlation coefficient (expressed as r ) shows the strength and direction of a relationship between two variables. The closer the r value is to +1 or -1, depending on how stronger the linear relationship between the two variables is.

Answer:

z = - 1 , z = 5

Step-by-step explanation:

| 3z - 6 | = 9

the absolute value function always gives a positive result, however, the expression inside can be positive or negative, that is

3z - 6 = 9 ( add 6 to both sides )

3z = 15 ( divide both sides by 3 )

z = 5

or

- (3z - 6) = 9

- 3z + 6 = 9 ( subtract 6 from both sides )

- 3z = 3 ( divide both sides by - 3 )

z = - 1

As a check

substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 5

| 3(5) - 6 | = | 15 - 6 | = | 9 | = 9 = right side

x = - 1

| 3(- 1) - 6 | = | - 3 - 6 | = | - 9 | = 9 = right side

then solutions are z = - 1 , z = 5

The point(s) on the curve y = x²/6 closest to the point (0,0) are (0,0) and (±√2, 2/3).

To find the point(s) on the curve y = x²/6 closest to the point (0,0), we can use the distance formula between two points:

d = √((x₁ - x₂)² + (y₁ - y₂)²)

where (x₁, y₁) is a point on the curve and (x₂, y₂) is the point (0,0).

We want to minimize the distance d, which is equivalent to minimizing d². Therefore, we can minimize:

d² = (x₁ - 0)² + (y₁ - 0)²

= x₁² + y₁²

subject to the constraint that the point (x₁, y₁) is on the curve y = x²/6.

Substituting y = x²/6 into the expression for d², we get:

d² = x₁² + (x₁²/6)

= (7/6)x₁²

To minimize d², we minimize x₁². Since x₁² is always non-negative, the minimum occurs when x₁² = 0 or when the derivative of d² with respect to x₁ is zero.

Taking the derivative of d² with respect to x₁, we get:

d²/dx₁ = (7/3)x₁

Setting this equal to zero, we get x₁ = 0.

Therefore, the point (0,0) is one of the closest points on the curve to the point (0,0).

To find the other closest point(s), we can solve y = x²/6 for x² and substitute it into the expression for d²:

x² = 6y

d² = 7x²/6 = 7y

Therefore, to minimize d², we need to minimize y. Since y is always non-negative, the minimum occurs when y = 0 or when the derivative of d² with respect to y is zero.

Taking the derivative of d² with respect to y, we get:

d²/dy = 7

Setting this equal to zero, we get y = 0.

Substituting y = 0 into y = x²/6, we get x = 0. Therefore, the point (0,0) is one of the closest points on the curve to the point (0,0).

To find the other closest point, we can solve y = x²/6 for x:

x² = 6y

x = ±√(6y)

Substituting this into the equation for y, we get:

y = (√(6y))²/6 = 2/3

Therefore, the other closest points are (±√2, 2/3).

Step-by-step explanation:

Angles that form a straight line add up to equal 180 degrees

Hence, e + 8 + 3e - 4 = 180

                      ^ ( note that we just created an equation that we can use to

                          solve for e )

Using the equation created, we then solve for e

e + 8 + 3e - 4 = 180

step 1 combine like terms

3e + e = 4e

8 - 4 = 4

we now have 180 = 4e + 4

step 2 subtract 4 from each side

180 - 4 = 176

4 - 4 cancels out

we now have 176 = 4e

step 3 divide each side by 4

176 / 4 = 44

4e / 4 = e

we're left with e = 44

Therefore, the surface represented by the given equation is a sphere centered at the origin with a radius of 6 units.

The given equation rho^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 represents a surface in spherical coordinates. Let's break down the equation to identify the surface:

ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36

Here, ρ represents the radial distance, φ is the polar angle, and θ is the azimuthal angle.

By analyzing the equation, we can see that it combines both the azimuthal and polar angles. The terms sin^2(φ)sin^2(θ) and cos^2(φ) involve both angles.

The equation ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 describes a sphere centered at the origin with a radius of 6 units. The constant value of 36 indicates that the squared radial distance from the origin to any point on the surface is 36.

Option C is the best model that describes the amount, A, in dollars with respect to time in the given scenario.

Here is the main answer:Option C is the best model that describes the amount, A, in dollars with respect to time in the given scenario.

This is because the formula for compound interest is A=P(1+r/n)^(n*t) where, A is the amount after t years, P is the principal or initial amount, r is the interest rate, and n is the number of times interest is compounded annually.So, in this case, A=10000(1+0.08/1)^(1*t)A=10000(1.08)^tTherefore, the correct option is C.

To solve this problem, we have to understand the concept of compound interest. Compound interest is the addition of interest to the principal amount of a loan or deposit, which results in an increase in the interest paid over time. The formula for compound interest is A=P(1+r/n)^(n*t) where,

A is the amount after t years, P is the principal or initial amount, r is the interest rate, and n is the number of times interest is compounded annually. Let's solve the problem.

Adam gets a student loan for $10,000 to start his school at 8% per year compounded annually.

He will have to repay the loan after t years from now. Which one of the following models best describes the amount,

A, in dollars with respect to time?We know that the principal amount is $10,000 and the interest rate is 8% per year compounded annually.

So, we can write the formula as follows:A=P(1+r/n)^(n*t)where P=$10,000, r=0.08, n=1, and t is the number of years. Now we can substitute these values in the formula and simplify to get the answer.A=10000(1+0.08/1)^(1*t)A=10000(1.08)^tTherefore, the correct option is C

. In conclusion, Option C is the best model that describes the amount, A, in dollars with respect to time in the given scenario.

Answer:

2/9 = approximately 0.22.

Step-by-step explanation:

There are a total of 12 possible outcomes when the spinner is spun once, so the probability of getting a result that is not green is 8/12, or 2/3. Similarly, the probability of getting green on the second spin is 4/12, or 1/3.

To find the probability of getting a result that is not green on the first spin and green on the second spin, you can multiply the probabilities of each individual event. Therefore, the probability of getting not green then green is (2/3) * (1/3) = 2/9 = approximately 0.22.

Alternatively, you could also use the principle of complementary probabilities to calculate the probability of getting not green on the first spin and green on the second spin. The probability of getting not green on the first spin is 1 - (4/12) = 8/12 = 2/3, and the probability of getting green on the second spin is still 4/12 = 1/3. Multiplying these probabilities gives a result of (2/3) * (1/3) = 2/9 = approximately 0.22.

No, the probability that a continuous random variable equals a certain value is zero does not imply that the probability of finding even or odd values is also zero.

The reason for this is that even and odd values are not specific points in the continuous probability distribution, but rather sets of points. For example, if we consider a uniform distribution over the interval [0, 1], the probability of any particular point in the interval is zero, including both even and odd values. However, the probability of finding an even value in the interval is 1/2, since half of the values in the interval are even. Similarly, the probability of finding an odd value is also 1/2. Therefore, the fact that the probability of a continuous random variable taking a certain value is zero does not imply anything about the probability of finding even or odd values.

The probability that Robert is approved on both the written application and the interview is approximately 0.5531

To find the probability that Robert is approved on both the written application and the interview, we can use the formula for conditional probability

P(A and B) = P(B | A) × P(A)

where A and B are events, P(A) is the probability of event A, and P(B | A) is the probability of event B given that event A has occurred.

Let's define the events

A = "Robert is approved on the written application"

B = "Robert is approved by the interview committee"

We know that P(A) = 0.67, and P(B | A) = 0.83. We want to find P(A and B), which represents the probability that both events A and B occur.

Using the formula for conditional probability, we have
