find the volume of the solid whose base is bounded by the circle x^2 y^2=4

The required answer is P(X=20) = 0.0919

To find the probability that Steph Curry shoots exactly 20 free throws (including the one he misses), we can use the binomial distribution formula:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

Where:
- X is the number of successes (made free throws)
- k is the specific number of successes we are interested in (20)
- n is the total number of trials (free throws attempted)
- p is the probability of success (making a free throw)

Since Steph Curry is a 91% free-throw shooter, we know that p = 0.91. We also know that he will keep shooting free throws until he misses, which means that the number of trials is not fixed. However, we can still use the formula by setting n = 20 (the maximum number of free throws he could make before missing).
A probability is a way of assigning every event a value between zero and one, with the requirement that the event made up of all possible results (in our example, the event {1,2,3,4,5,6}) is assigned a value of one. To qualify as a probability, the assignment of values must satisfy the requirement that for any collection of mutually exclusive events (events with no common results, such as the events {1,6}, {3}, and {2,4}), the probability that at least one of the events will occur is given by the sum of the probabilities of all the individual events

Now, we just need to calculate P(X=20):

P(X=20) = (20 choose 20) * 0.91^20 * (1-0.91)^(20-20)
P(X=20) = 0.0919
So the probability that Steph Curry shoots exactly 20 free throws (including the one he misses) is approximately 0.0919, or 9.19%.

We are given that Steph Curry is a 91% free-throw shooter, which means he has a 91% chance of making each free throw and a 9% chance of missing one. We want to find the probability that he shoots exactly 20 free throws, including the one he misses.
probability that at least one of the events will occur is given by the sum of the probabilities of all the individual events

In uniform probability distributions, the likelihood of each possible outcome happening or not is the same. This property means that, for any given trial, the probability that an event will be successful does not change

Step 1: Calculate the probability of making the first 19 free throws. Since each free throw has a 91% chance of success, the probability is 0.91^19.

Step 2: Calculate the probability of missing the 20th free throw. This is a 9% chance or 0.09.

Step 3: Multiply the probability of making the first 19 free throws by the probability of missing the 20th one to find the overall probability. This is (0.91^19) * 0.09.

The probability that Steph Curry shoots exactly 20 free throws, including the one he misses, is approximately 0.0357 or 3.57%.

Answer:

x > 1/6.

Step-by-step explanation:

–2(8x – 4) < 2x + 5

-16x + 8 < 2x + 5

-18x < -3

x > 1/6.

The solution to the inequality expression is x > 1/6

Given the inequality expression

–2(8x – 4) < 2x + 5

Expand the parenthesis

-16x + 8 < 2x + 5

Subtract 5 from both sides

-16x + 8 - 5 < 2x + 5 - 5

-16x + 3 < 2x

-16x - 2x < -3

-18x < -3

The statement ''the symbol μ ˆ p represents the proportion of a sample of size n, not the proportion of a sample of size n.'' is false because the symbol "μ ˆ p" does not represent the proportion of a sample of size n.

In statistical notation, the symbol "μ ˆ p" typically represents the sample proportion, which is an estimate of the population proportion. The sample proportion is obtained by dividing the number of occurrences of a specific event in the sample by the sample size.

On the other hand, the population proportion, denoted by "p," represents the proportion of the entire population that exhibits a certain characteristic or has a specific attribute.

The symbol "μ ˆ p" could be a typographical error or a confusion between different symbols used in statistics. The correct symbol to represent the sample proportion is usually denoted as "p ˆ" or "p-hat." The symbol "μ" typically represents the population mean.

Therefore, it is incorrect to state that "μ ˆ p" represents the proportion of a sample of size n.

The given statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is False.

The union of two events A and B represents the event that at least one of the events A or B occurs. The probability of the union of two events can be calculated using the formula:

P(A or B) = P(A) + P(B) - P(A and B)

On the other hand, the intersection of two events A and B represents the event that both events A and B occur. The probability of the intersection of two events can be calculated using the formula:

P(A and B) = P(A) * P(B|A)

where P(B|A) is the conditional probability of B given that A has occurred.

It is possible for the probability of the union of two events to be greater than the probability of the intersection of two events if the two events are not mutually exclusive.

In this case, the probability of both events occurring together (the intersection) may be relatively small, while the probability of at least one of the events occurring (the union) may be relatively high.

In summary, the probability of the union of two events occurring can sometimes be greater than the probability of the intersection of two events occurring, depending on the relationship between the events.

She did mistake in Step 2 when she take -3y common then the term should be: -3y(x+5) instead she wrote -3y(x-5)

Correcting the mistake:

\(Step \ 1: 4x^2 + 20x - 3xy - 15y\\Step \ 2: 4x(x + 5)\mathbf{- 3y(x +5)}\\Step \ 3: (x+5)(4x - 3y)\)

We have found two quadratic functions with x-intercepts (-5,0) and (5,0): f(x) =\(x^2 - 25\), which opens upward, and g(x) = \(-x^2 + 25\), which opens downward.

For the quadratic function that opens upward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:

f(x) = a(x + 5)(x - 5)

where a is a constant that determines the shape of the parabola. If this function opens upward, then a must be positive. Expanding the equation, we get:

f(x) = a(x^2 - 25)

To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open upward, we need the coefficient of x^2 to be positive, so we can set a = 1:

f(x) = x^2 - 25

For the quadratic function that opens downward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:

g(x) = a(x + 5)(x - 5)

where a is a constant that determines the shape of the parabola. If this function opens downward, then a must be negative. Expanding the equation, we get:

g(x) = a(x^2 - 25)

To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open downward, we need the coefficient of x^2 to be negative, so we can set a = -1:

g(x) = -x^2 + 25

We note that c is a positively-oriented, smooth, simple closed curve. Green's theorem tells us that in this situation, if d is the region bounded by c, then p dx + q dy = (∂q/∂x - ∂p/∂y) dA

Based on the given information, we can apply Green's Theorem, which states that for a positively-oriented, smooth, simple closed curve c and the region d bounded by c, the line integral of the vector field (p, q) over c is equal to the double integral of the curl of (p, q) over d.

Green’s theorem is mainly used for the integration of the line combined with a curved plane. This theorem shows the relationship between a line integral and a surface integral.

It is related to many theorems such as Gauss theorem, Stokes theorem.

Green’s theorem is used to integrate the derivatives in a particular plane. If a line integral is given, it is converted into a surface integral or the double integral or vice versa using this theorem.

Green’s theorem is one of the four fundamental theorems of calculus, in which all of four are closely related to each other.

Green’s theorem defines the relationship between the macroscopic circulation of curve C and the sum of the microscopic circulation that is inside the curve C. Using the notation for the partial derivatives, we can express this as:

p dx + q dy = (∂q/∂x - ∂p/∂y) dA

Therefore, the missing terms in the equation would be q and p, respectively:
p dx + q dy = (∂q/∂x - ∂p/∂y) dA
p dx + q dy = (∂q/∂x - ∂p/∂y) dA
p dx + q dy = (∂q/∂x - ∂p/∂y) dA

The cost of nails can be represented as 12.99n, and the cost of screws can be represented as 14.99s.

The cost of buying nails and screws can be represented by a system of inequalities where "n" represents the number of boxes of nails and "s" represents the number of boxes of screws.

The cost of one box of nails is $12.99 and the cost of one box of screws is $14.99. Hence, the cost of "n" boxes of nails is represented by 12.99n and the cost of "s" boxes of screws is represented by 14.99s. The carpenter has a budget of $60 and can spend no more than that.

Therefore, the combined cost of buying nails and screws must be less than or equal to $60. This requirement can be represented by the inequality 12.99n + 14.99s <= 60.

To make the calculation easier, we can also express the inequality as n + s <= 4.62, where 4.62 is obtained by dividing $60 by $12.99. This system of inequalities represents the carpenter's budget constraint and helps to determine the number of boxes of nails and screws that can be purchased within the budget.
