7 pairs of a are sold and 9 pairs of b are sold.

The equation that will be used in solving the equation will be:

a + b = 16 ......... i

45a + 30b = 585 ......... ii

From equation i,

a = 16 - b ...... iii

Put equation iii into ii

45a + 30b = 585.

45(16 - b) + 30b = 585.

720 - 45b + 30b = 585.

Collect like terms

-45b + 30b = 585 - 720

-15b = -135

b = 135/15.

b = 9

Since a + b = 16

a = 16 - b

a = 16 - 9

a = 7

Therefore, 7 pairs of a are sold and 9 pairs of b are sold.

If the variables "r" and "s" are inversely proportional and r=7 when s=6 , then when r = 10 , value of "s" will be 4.2 .

When the two variables are inversely proportional, their product is constant. That means, for two variables "r" and "s" , the it is represented in equation as :

⇒ r × s = k, where k is a constant ;

the value of variable "r" = 7 when s = 6,

First , we have to find the value of k:

⇒ k = r × s = 7 × 6 = 42 ;

So, for any value of r and s, the product "rs" will always be equal to 42.

When r = 10, we can use the equation to find s:

⇒ s = k/r = 42/10 = 4.2

Therefore , when r = 10 , the variable "s" is 4.2.

Option E should be chosen, which is to explore the assignable causes because the second, fourth, and fifth samples are above the mean.

In an x-bar chart, the control limits (UCL and LCL) are based on the process variability and are used to determine if the process is in control. The central line represents the mean of the process.

Looking at the given sample means of 18, 23, 17, 21, 24, and 16, we can see that the second, fourth, and fifth samples are above the mean of 20. This suggests a potential shift or deviation from the expected process mean.

In an x-bar chart, if any sample mean falls outside the control limits or exhibits a non-random pattern, it indicates the presence of assignable causes, which are factors that can be identified and addressed to improve the process. Since the second, fourth, and fifth samples are above the mean, it is advisable to explore the assignable causes, as stated in option E.

Therefore, the correct option is (b) 46 that is the number of students who like Twix and Reese's peanut butter cups only (region D) by principle of inclusion-exclusion, we need to subtract the number of students who like Snickers, as well as the number of students who like all three kinds of candy, from the number of students who like Twix and Reese's peanut butter cups along with one or both of the other kinds of candy.

We can start by using the principle of inclusion-exclusion, which tells us that:

|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|

where |X| denotes the number of elements in set X.

Using the numbers given in the problem, we have:

|A| = 129

|B| = 118

|C| = 145

|A ∩ B| = 22

|B ∩ C| = 54

|A ∩ C| = 55

|A ∩ B ∩ C| = 8

Substituting these values into the formula, we get:

|A ∪ B ∪ C| = 129 + 118 + 145 - 22 - 55 - 54 + 8 = 269

This tells us that 269 students like at least one of the three kinds of chocolate candy.

To find the number of students who like Twix and Reese's peanut butter cups only (region D), we need to subtract the number of students who like Snickers, as well as the number of students who like all three kinds of candy, from the number of students who like Twix and Reese's peanut butter cups along with one or both of the other kinds of candy:

Step by step Explanation:

The question is incomplete as the plots that show the distance traveled is not given.

So, I will answer the question with the attached plots.

The number of dots on each day represents the number of miles travelled on that day.

From Elizabeth's plot, the shortest is 1 mile on day 4 (i.e. 1 dot on day 4)

From Izak's plot, the shortest is 2 miles on day 3 (i.e. 2 dots on day 3)

Calculate the difference between both distances

\(d = 2\ miles - 1\ mile\)

\(d = 1\ mile\)

Hence, the shortest distance travelled by Izak is 1 mile more than the shortest by Elizabeth

Answer: Domain is \([0,\infty)\) and range is [0,4000].

Step-by-step explanation:

It is given that, the set of ordered pairs (t,d), where

t = the time in seconds after  someone jumps out of a plane at  4000 meters to go skydiving

d = is the displacement above the  ground.

It means t is independent variable and it is represented on the x-axis.

d is dependent variable and it is represented on the y-axis.

We need to find the domain and Range.

Domain is the set of input values.

Here, input is time and time can not be negative.

Domain \(=0\leq t=[0,\infty)\)

Range is the set of output values.

Here, output is displacement above the  ground which can not be negative or more than 4000 meters.

Step-by-step explanation:

it depends on how many choices there are

If there is 1 choice for an appetizer, 1 choice for an entrée, and 1 choice for a dessert

(1 * 1 * 1 = 1)

then there is 1 meal choice

If there are 7 choices of appetizers, 12 choices of entrée, and 6 choices of dessert.

(7 * 12 * 6 = 504)

then there are 504 different options

If there are 5 choices for an appetizer, 12 choices for an entrée, and 3 choices for a dessert

(5 * 12 * 3 = 180)

then there are 180 options

12 choices for entrées, 10 choices for side dishes, and 6 choices for dessert

(12 * 10 * 6 = 3240)

then there are 3240 meal options

you have to multiply the number of entrées (e), meals (m), and desserts (d)

e * m * d = x

you are solving for x, which is the different meals available aka your answer.

For f(x) to be a valid PDF, integrating f(x) dx over the support of x must be equal to 1. The above statement is true.

For a function f(x) to be a valid probability density function (PDF), it must satisfy two conditions:
1. f(x) must be non-negative for all values of x within its support, meaning that f(x) ≥ 0 for all x.
2. The integral of f(x) dx over the support of x must equal 1. This condition ensures that the total probability of all possible outcomes is equal to 1, which is a fundamental property of probability.
In mathematical terms, if f(x) is a PDF with support A, then the following conditions must be satisfied:
1. f(x) ≥ 0 for all x in A.
2. ∫(f(x) dx) over A = 1.

Answer:

Step-by-step explanation:

Answer:

The probability of  getting B=40 is \(0.11\times 10^{-11}\) which is negligible.

Step-by-step explanation:

Given that 31 percent of the residents of a certain state who are age 25 years or older have a bachelor’s degree.

Assuming the population of the state aged 25 years or more is Bernoulli's population.

So, when 1 person aged 25 years or more from the state selected randomly, the probability of that person, p, having a bachelor’s degree,

\(p= 31/100=0.31\cdots(i)\)

Now, according to Bernoulli's formula, the probability of exactly r success from the total number of sample n is

\(P(r)=\binom{n} {r}p^r(1-p)^{n-r}\cdots(ii)\)

where p is the probability of success.

Here, a random sample of 50 residents of the state, age 25 years or older, will be selected.

So, n=50.

Given that variable B represents the number in the sample who have a bachelor’s degree,

We have to find the probability that B will equal 40.

So, r=B= 40.

Now, putting these values in equation(ii) and using p=0.25 from equation (i), we have

\(P(r=40)=\binom{50} {40}(0.31)^{40}(1-0.31)^{50-40}\)

\(=\frac {50!}{40! (50-40)!}(0.31)^{40}(0.69)^{10} \\\\=\frac {50!}{40! \times 10!}(0.31)^{40}(0.69)^{10} \\\\=0.11\times 10^{-11}\)

So, the probability of  getting B=40 is \(0.11\times 10^{-11}\) which is negligible.

Using the binomial distribution, it is found that there is a \(1.13 \times 10^{-12}\) probability that B will equal 40.

-----------------------------

For each resident, there are only two possible outcomes. Either they have a bachelor's degree, or they do not. The probability of a resident having a bachelor degree is independent of any other resident, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)  

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

p is the probability of a success on a single trial.

In this problem:

The probability is:

\(P(B = 40) = C_{50,40}(0.31)^{40}(0.69)^{10} = 1.13 \times 10^{-12}\)  

\(1.13 \times 10^{-12}\) probability that B will equal 40.

Answer:

To increase a price, add the percentage you wish to increase it by to 100%, convert the percentage into a decimal by dividing by 100, then multiply this by the original price.

To decrease a price, subtract the percentage you wish to decrease it by from 100%, convert the percentage into a decimal by dividing by 100, then multiply this by the original price.

-------------------------------------------------------------------------------------------------

100% represents the original price.

Therefore, 100% = $599.99

A 20% discount means that the price is now 80% of the original price,
as 100% - 20% = 80%

To find 80% of the original price, convert 80% to a decimal and multiply it by the original price:

80% = 80/100 = 0.8

Therefore, 80% of $599.99 = 0.8 x $599.99

                                              = $479.992

Finally, we need to apply a sales tax of 6%.  We can do this in 2 ways:

Way 1

Work out 6% of the discounted price, then add this to the discounted price to find the final price:

Sales tax = 6% of $479.992

               = 0.06 x $479.992

               = $28.79952

Final price = discounted price + sales tax

                  = $479.992 + $28.79952

                  = $508.79 (nearest cent)

Way 2

We need to increase the discounted price of $479.992 by 6%.  Therefore, the final price will be 106% of the discounted price as
100% + 6% = 106%

Final price = 106% of discounted price

                  = 1.06 x $479.992

                  = $508.79 (nearest cent)

False. The statement is not true. The inclusion or exclusion of Investor-State Dispute Settlement (ISDS) provisions in the Free Trade Agreement (FTA) between the United States and Australia does not directly impact Philip Morris USA's decision to establish a subsidiary in Malaysia and sue the Australian government over the Tobacco Plain Packaging Act.

Philip Morris USA, a subsidiary of Philip Morris International, did take legal action against the Australian government over the Tobacco Plain Packaging Act. However, the basis for the lawsuit was not related to the ISDS provisions in the FTA between the US and Australia. Instead, Philip Morris argued that the plain packaging legislation violated its intellectual property rights, specifically the trademark and branding of its tobacco products.

It's important to note that the US-Australia FTA, which came into effect in 2005, did not include an ISDS mechanism. Therefore, the false statement in question incorrectly connects the absence of ISDS in the FTA with Philip Morris USA's decision to file a lawsuit in Malaysia against the Australian government.
