1) The initial volume of a balloon is 0.50 L. The initial temperature of the balloon is 150K. The volume in the balloon increase

d to 1.00 L.
What is the final temperature?

Use the below equation. Round to the nearest whole number and do not use units in your final answer.

T2=V2 x T1V1

2) A 2.5L container of an unknown gas has a pressure of 300kPa. The container is squeezed and has a final volume of 2.0L.

What is the final pressure of the container?
Use the below equation. Round to the nearest whole number and do not use units.

P2 =P1V1/V2

3) Charles’ law is
V1T1=V2T2
A closed container has an initial temperature of 300K. The container volume is changed until the final volume is 2L and the final temperature is 425K.

Calculate the initial volume using the equation from Charles' Law.

Use 2 decimal points in your answer and do not use units.

Is the number of members of Club X greater than the number of members of Club Y ? (1) Of the members of Club X, 20 percent are a
Oliga [24]

Answer:

Yes

Step-by-step explanation:

The 20% of members of club X that are also members of club Y can be written as: P(Y/X) = 20% (that is, the probability of belonging to Y given that it belongs to X)

The 30% of members of club Y that are also members of club X can be written as: P(X/Y) = 30% (that is, the probability of belonging to X given that it belongs to Y)

The formula of conditional probability of A given B is  

P(A/B) = (A∩B) / P(A)

Where (A∩B) is the probability that both events A and B occur and P(A) is the probability of A.

Based on that, we can write,

P(Y/X) = P(Y∩X) / P(X) = 20 % = 0.2

P(X/Y) = P(Y∩X) / P(Y) = 30 % = 0.3

Clearing P(Y∩X) of both equations and equalizing,

P(Y/X).P(X) = P(X/Y).P(Y)

Moving terms ,

P(X) / P(Y) = P(X/Y) / P(Y/X) = 0.3 / 0.2 = 1.5

That is, P(X) is 1.5 times P(Y), which means that the amount of members of X is greater than the members of Y.

James estimated the total cost of groceries to be $50. The actual cost of the groceries is $65. What is the percent error? Round
Yuki888 [10]

The percentage error is 23%

Explanation:

The estimated total cost of the groceries = $50

The actual cost of the groceries = $65

To find the error value, we need to subtract the value of actual cost and total cost of the groceries.

Thus,

error value = actual cost - total cost

error value = 65-50=15

Hence, error value = $15

The formula to determine the percent error is given by

Percent error $=\left(\frac{\text { error value}}{\text {actual value}}\right) \times 100$

Substituting the values in the formula, we get,

$\begin{aligned} \text { Percent error } &=\left(\frac{15}{65}\right) \times 100 \\ &=0.231 \times 100 \\ &=23.1 \end{aligned}$

Rounding off the value, we have, 23%

Thus, the percentage error is 23%
