whats the probability of suriving the second try given his survival in the first try if he doesn't spin the cylinder

Answer:

Step-by-step explanation:

We can use the proportionality relationship between force and acceleration, which is given as:

force = constant × acceleration

Let's call the constant of proportionality k. Then we can write:

40 N = k × 4 m/s^2

Solving for k, we get:

k = 40 N / 4 m/s^2 = 10 Ns^2/m

Now we can use this value of k to find the force required for an acceleration of 9 m/s^2:

force = k × acceleration = 10 Ns^2/m × 9 m/s^2 = 90 N

Therefore, the force required for an acceleration of 9 m/s^2 is 90 N.

Charlie's utility function is given by U(A, B) = AB, where A is the number of apples he consumes and B is the number of bananas he consumes. The price of apples is $1, and the price of bananas is $2.

If Charlie's income is $120, he has a budget constraint given by:

1A + 2B = 120

To maximize his utility subject to this budget constraint, Charlie must use his income to purchase the combination of apples and bananas that gives him the greatest value of U(A, B).

The solution to this problem can be found by using the method of Lagrange multipliers. From the budget constraint, we can solve for A in terms of B:

A = 120 - 2B

Substituting this into the utility function, we have:

U(B) = (120 - 2B)B = 120B - 2B^2

To maximize U(B), we must find the value of B that maximizes this expression. Taking the derivative of U(B) with respect to B and setting it equal to zero, we find that:

dU/dB = 120 - 4B = 0

Solving for B, we find that:

B = 30

Thus, if Charlie chose the bundle that maximizes his utility subject to his budget constraint, he would consume 30 units of bananas. The answer is therefore a. 30.

The approximate percent increase in consumption from 1986 to 1997 is:

B. 20%

The initial consumption level for the year, 1986 is 62 million barrels per day and by 1997, the percent increase in consumption shot up to 74 million barrels per day.

When we subtract the latter consumption levels from the former, we will have a total of 12 million barrels per day. So, the percentage increase will be:

12 million barrels per day/ 62 million barrels per day × 100

= 19.35 %

Thus, we can arrive at the conclusion that the total consumption levels per day increased by 19.35%, which is approximately 20%.

-9x-7i > 9x-21u

-7i > -21u

-i > -3u

i < 3u

Answer:

Step-by-step explanation:

You want the domain and range of the function ...

  F(x) = (x -6)/(x² -3x -18)

We can simplify the function to ...

  [tex]F(x) = \dfrac{x-6}{x^2-3x-18}=\dfrac{x-6}{(x-6)(x+3)}\\\\F(x)=\dfrac{1}{x+3}\quad x\notin\{-3,6\}[/tex]

The domain is the set of x-values for which the function is defined. It is undefined where the denominator is zero. So, x=-3 and x=6 are excluded from the domain, which would otherwise be all real numbers.

The range is the set of values that the function may have. Here, the function can have any y-value except 0 (the value of the horizontal asymptote), and 1/9, the location of the "hole" at x=6.

The range is all real numbers except 0 and 1/9.

The counterexample proves that the converse of the theorem is not always true, and we have to be careful when making statements about limit points and convergence of sequences.

A sequence is a set of numbers that are generated one after the other in a specific pattern.

The theorem states that if a sequence converges, it will have exactly one limit point. In other words, if a sequence is getting closer and closer to a certain number, there will be only one number that it approaches. This is a fundamental idea in mathematics, and it is important to understand why it is true.

To prove this theorem, let's consider a sequence (a_n) that converges to a limit L. If there were two different limit points, say L1 and L2, then there would be a contradiction. This is because by definition, the sequence (a_n) would be getting closer and closer to L1 and L2 at the same time, which is not possible. Hence, it must be true that the sequence (a_n) has exactly one limit point, L.

The converse of this theorem is not always true. In other words, just because a sequence has exactly one limit point, it doesn't necessarily mean that it converges to that limit. To see why this is the case, let's consider the following sequence:

(2, 3, 4, 5, 6, ...)

In this sequence, the limit point is 6. However, the sequence does not converge to 6 because it is not getting closer and closer to 6 as it goes on. Instead, it is increasing by 1 with each term, and therefore it does not converge.

Answer:

To turn -5/7 and 8 into a quadratic equation, we first need to convert 8 into an equation by adding 8 to both sides. The equation becomes: -5/7 = x^2 + 8. Then, we can expand the right side into a complete square, using the formula (b/2)^2. The equation becomes:

-5/7 = (x^2 + 8) + (4/2)^2

-5/7 = x^2 + 8 + 4

-5/7 = x^2 + 12

Finally, we can rearrange the equation to make the right side equal to 0, and then factor it. The final equation is:

x^2 + 12 + 5/7 = 0

x^2 + 12 + 5/7 = (x + 6/√7)(x + 6/√7) = 0

Step-by-step explanation:

In the first step, we added 8 to both sides to make the equation -5/7 = x^2 + 8. In the next step, we added 4 to the right side to complete the square. The purpose of completing the square is to get a perfect square on the right side, which will make it easier to factor the equation.

Next, we rearranged the equation to make the right side equal to 0, so that we can factor the equation. The equation x^2 + 12 + 5/7 = 0 can be factored as (x + 6/√7)(x + 6/√7) = 0, where (x + 6/√7) is a binomial that satisfies the equation.

Answer: C. The most accurate measure of center to represent the data in this case is the median of 20.

Step-by-step explanation: The median is the middle value in a dataset when the data is arranged in ascending or descending order. In this case, the donations are: 10, 10, 10, 10, 15, 15, 15, 19, 20, 20, 20, 25, 25, 25, 30, 30, 55, 55.

When we arrange these values in ascending order, we get: 10, 10, 10, 10, 15, 15, 15, 19, 20, 20, 20, 25, 25, 25, 30, 30, 55, 55.

The median is the value that separates the dataset into two equal halves. In this case, there are 18 values, so the middle value is the 9th value, which is 20.

The reason the median is the most accurate measure of center to use in this case is because the data is skewed. Skewness refers to the asymmetry in the distribution of data. In this case, the data is skewed to the right because there are a few large values (55) that pull the mean higher than the majority of the values.

Using the mean, which is calculated by summing all the values and dividing by the total number of values, would be influenced by these large values and may not accurately represent the typical donations received by the charity.

Answer:

12% of the items in the group are red and have stripes.

Step-by-step explanation:

Aassume that there is 100 items, 40 items red.

In the 40 items, 30% are striped.

40×(30/100)=12%

12% of the items in the group are red and have stripes. This is found by multiplying the proportion of red items (40%) by the proportion of these red items that also have stripes (30%).

We are given that 40% of items in a group are red. This is represented as 40/100, or 0.40. The question mentions that out of these red items, 30% also have stripes. This can be represented as 30/100, or 0.30. The question requires us to find out what percentage of the total items in the group are red and have stripes. To find this, we multiply 0.30 (the proportion of red items that are striped) by 0.40 (the proportion of items that are red).

So, 0.30 x 0.40 = 0.12 or 12%.

Therefore, 12% of the items in the group are red and have stripes.
