which was 6 RM 6 which means he out 14 apples in hot water 6 times and he remains with 6 apples(I don't know what he does with those) but since he puts 14 apples 6 times for 3 hours multiply 6×3=18 hours again, I'm not sure if this is correct at all but I hope I at least triggered something that you can think of?

In linear programming, solutions that satisfy all of the constraints simultaneously are referred to as feasible solutions. These feasible solutions represent all the possible combinations of values for the decision variables that satisfy the constraints of the problem.

The main objective of linear programming is to find the optimal feasible solution that maximizes or minimizes a given objective function. The objective function represents the goal that needs to be achieved, such as maximizing profit, minimizing cost, or maximizing efficiency.

To find the optimal feasible solution, a linear programming algorithm is used to analyze all the possible combinations of decision variables and evaluate their objective function values. The algorithm starts by identifying the feasible region, which is the area that satisfies all the constraints.

Then, the algorithm evaluates the objective function at each vertex or corner of the feasible region to find the optimal feasible solution. The optimal feasible solution is the one that provides the best objective function value among all the feasible solutions.

Therefore, In linear programming, solutions that satisfy all of the constraints simultaneously are referred to as: linear programming

In summary, linear programming involves finding feasible solutions that satisfy all the constraints of the problem, and then selecting the optimal feasible solution that provides the best objective function value.

The notation used for a vector pointing into the point is X.

A quantity with a magnitude and direction is called a vector. A vector quantity will be identified in these annotations by a bold letter (such as the electric field vector E). Vectors appear graphically as straight arrows. The magnitude of the vector is commonly represented by the length of the arrow, and both the arrow and the vector point in the same general direction.

Arrows are drawn on the page to represent vectors in the page's plane. Typically, circles with an X engraved on them are used to represent vectors that enter the screen's plane. A vector that deviates from the screen's plane is often represented by circles with dots in the center.

If an acute angle increases, then its supplement decreases.

To give you a short quick answer, the supplement is going to have to decrease or get smaller.

Example

Suppose the acute angle is 10 (anything under 90 will do).

Then the supplement is going to be 180 - 10 = 170

Now suppose the acute angle increase to 50 degrees.

That means the supplement will go from 180 - 50 = 130

Conclusion

As the acute angle gets bigger, the supplement gets smaller. This is an important idea to get clear. Bigger and Smaller or More or Less can be ugly little words, so anytime you come across them, pay attention. It will make your life in science so much easier

Answer:

a, \(Books = 315\)

b, \(Total = 20s + 45l\)

Step-by-step explanation:

Given

\(Small\ Box = 20\)

\(Large\ Box = 45\)

Solving (a): Books using 5 small and 7 large boxes;

This is calculated as follows

\(Books = Size * quantity\)

For Small box

\(Books = 20 * 5\)

\(Books = 100\)

For large box:

\(Books = 45 * 7\)

\(Books = 315\)

\(Total = 100 + 315\)

\(Total = 415\ books\)

Solving (b): s small and l large

We use the same concept as (a) above:

For Small Box

\(Books = 20 * s\)

\(Books = 20s\)

For large box

\(Books = 45 * l\)

\(Books = 45l\)

\(Total = 20s + 45l\)

By compound interest, The initial amount in the account is $300.

What does compound interest mean ?

When you earn interest on your interest earnings as well as the money you have saved, this is known as compound interest. As an illustration, if you put $1,000 in an account that offers 1% yearly interest, you will receive $10 in interest after a year.

                             Compound interest allows you to earn 1 percent on $1,010 in Year Two, which equates to $10.10 in interest payments for the year. This is possible because interest is added to the principle in Year Two.

A = 300(1.035)t

As we know the formula "Compound Interest" :

A = P(1 + r/100)t

So, According to our question,

Rate of interest = 0.35 = 135%

So, equate the both the equations , we get that

Hence, The initial amount in the account = $300

Answer:

Step-by-step explanation:

I'm uncertain as to the "best statement."  None seem to accurately describe the situation. I picked the one that was least incorrect (if that makes any sense).

Step 1: Find dy/dx

If xy = 36, then y = 36/x or y = 36 x^(-1).

dy/dx = -36/x^2

Step 2: evaluate dy/dx at (9,4).

dy/dx at (9,4) = -36/(9^2) = -4/9

Step 3: put together your equation in point-slope form:

y - 4 = -4/9(x-9)

or put that into slope-intercept form:

y = -4/9x +8

The range thumb rule The minimum and maximum values for the usual value, which is two, are 812.14 and 885.85, respectively.

An efficient way to calculate the range from the standard deviation is to use the range rule of thumb. The range is normally around four times the standard deviation, according to this information. Inferring that your range is around eight if your standard deviation is 2, for example.

As an illustration of a binomial distribution, we'll utilize seeds.

According to given data;

Let "X" represent the number of tomato seeds that actually germinate based on the data provided.

With the knowledge provided above, we can now determine the:

The median number of seeds that we may anticipate to germinate

standard deviation (σ): sqrt of n*p*(1-p)

Once you calculate the mean and standard deviation, you can calculate the minimum usual value and the max usual value.

Now, in your problem:

n = 1415

p = 3/5

so,

the mean would be: (1415)(3/5) = 849

the standard deviation would be:  sqrt (mean)(1-3/5) = 18.4282

Next, we find the minimum and maximum usual values according to the equations you gave:

minimum:  mean - 2(standard deviation)

                = 849 - 2(18.4282)

                = 812.1436

maximum: mean + 2(standard deviation)

                = 849 + 2(18.4282)

                = 885.8564

Step-by-step explanation:

Option (E) there's a 99% chance the percentage of people with a college degree in the town is somewhere between 65% and 71%.

We can analyze the statements and determine which ones are correct conclusions based on the provided 99% confidence interval for the percentage of people in a town who have a college degree.

A. There is a 99% chance that a confidence interval constructed this way from a simple random sample contains the true percentage of people with a college degree in the town.

This statement is incorrect.

The interpretation of a confidence interval is not based on the probability of containing the true parameter value.

Instead, it means that if we were to repeat the sampling and construct confidence intervals in the same way, 99% of those intervals would contain the true parameter value.

B. Between 65% and 71% of people in the town have a college degree.

This statement is incorrect.

The confidence interval provides a range of values that is likely to contain the true percentage of people with a college degree in the town, but it does not guarantee that the true value lies within that range.

It only provides a level of confidence in the estimation.

C. All the values between 65% and 71% are reasonable estimates of the percentage of people with a college degree in the town.

This statement is incorrect.

The confidence interval provides a range of reasonable estimates, but individual values within that range cannot be considered as precise estimates.

The true percentage could be any value within the interval, not just the endpoints.

D. The sample percentage was 68.

This statement is not directly supported by the given information.

The sample percentage is not explicitly provided, and we cannot determine its value based solely on the confidence interval.

E. There's a 99% chance the percentage of people with a college degree in the town is somewhere between 65% and 71%.

This statement is correct. The confidence interval indicates that, with 99% confidence, the true percentage of people with a college degree in the town is likely to fall between 65% and 71%. It provides a range within which the true value is expected to lie.

Therefore, the correct conclusions based on this result are:

Statement E: There's a 99% chance the percentage of people with a college degree in the town is somewhere between 65% and 71%.

Statement: XW/UT = XV/UV Reason: Corresponding sides of similar triangles are proportional

Similar triangles are defined as triangles that have the same shape, but then their sizes may vary. Thus, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

Now, we see from the two column proof that ΔTVU ∼ ΔWVX. This means that corresponding sides of both triangles are proportional or have corresponding proportions.

The standard error for the estimate of the proportion of all persons aged 65 and over with osteoarthritis is 0.0092.

The subset chosen from the larger set to make assumptions is known as a random sample. Standard Error can be defined as the term that measures the accuracy of the sample distribution which represents the population.

We know that,

                   Standard Error   =   √ ( P ( 1 - P ) / n )    → 1

As per the given question,

Substitute the values in 1,

Standard Error ( SE )   =   √ ( P ( 1 - P ) / n )

                                    =   √ ( 0.115 ( 1 - 0.115 ) / 1200 )

                                    =   √ ( 0.115 ( 0.885 ) / 1200 )

                                    =   √ ( 0.101775 / 1200 )

                                    =   √ ( 0.0000848125)

Standard Error ( SE )   =   0.0092093702   ≅   0.0092

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

i.e.

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

So,

The proportion of a normal distribution is 38.2%.

Hence we can say that the proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.
