Pauline, Patricia and Polly are pie bakers at their bakery, Perfect Pies. They bake four different pie flavors: cherry, blueberry, apple and pecan. I understand question #1 but I need someone to help with questions 2-6 please.

a. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores. b. The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.

(a) To find the probability that the sample mean will be within ±5 of the population mean, we can use the Central Limit Theorem (CLT) and the properties of a normal distribution.

The sample mean, is an unbiased estimator of the population mean, μ. According to the CLT, the distribution of sample means approaches a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

     = 200 / √400

     = 200 / 20

     = 10

To find the probability that the sample mean will be within ±5 of the population mean, we can standardize the interval using the z-score:

For the lower bound (-5), the z-score is (-5 - 0) / 10 = -0.5.

For the upper bound (+5), the z-score is (5 - 0) / 10 = 0.5.

We can now use a standard normal distribution table or technology (such as a calculator or statistical software) to find the probability associated with the z-scores -0.5 and 0.5. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores.

(b) To find the probability that the sample mean will be within ±10 of the population mean, we follow the same steps as in part (a).

The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.

Note: Since the question mentions rounding answers to four decimal places, please use the appropriate table or technology to obtain the precise probabilities for parts (a) and (b).

The value of 5 - 4x is 7/3, which is equivalent to option (d) d. 17

If 7x³ = 24, we can solve for x by taking the cube root of both sides:

\((7x^3)^{1/3} = (24)^{1/3} \\x = (24)^{1/3} \div7^{1/3}\)

To find the value of 5 - 4x, we can substitute the expression for x into the second equation:

5 - 4x = \(5 - 4(24)^{1/3} \div 7^{1/3\)

Simplifying, we get

5 - 4x = 5 - 4(2/3)

5 - 4x = 5 - (8/3)

5 - 4x = (15/3) - (8/3)

The dimensions of the dumpster that will minimize its surface area are Length = 4.43 yds ,Width  = 2.215 yds and Height  = 2.956 yds

since l = 2w.

Now, the formula for a cube's surface area is;

S = 2lw + 2lh + 2wh.

Changing 2w to l yields;

S = 4wh + 4w² + 2wh.

S = 4w² + 6wh

in the meantime, the formula for a cube's volume is;

V = lwh

add 2w for l to receive;

V = 2w²h

h = V/2w²

In the SA equation, substitute V/2w² for h to get;

SA = 4w² + 6w(V/2w²)

SA = 4w² + 3V/w

V is stated to equal 29 yd3.

Thus;

S = 4w² + 87/w

Let's find the first derivative of S as we want to reduce the surface area;

S' = 8w - 87/w²

At S' = 0;

8w - 87/w² = 0

8w = 87/w²

w³ = 87/8

w = ∛(87/8)

w = 2.215 yds

L = 2 x 2.215= 4.43

since, l = 2w.

l = 4.43 yds

h = V/2w²;

h = 29/(2 × 2.215²)

h = 2.956 yds

Hence, The dimensions of the dumpster that will minimize its surface area is l = 4.43 yds, w = 2.215 yds and h = 2.956 yds

Answer:

it will take Larissa 4 17/27 hours to finish 5lbs of goldfish

Step-by-step explanation:

1.5 pound = 1 1/2 pound equivalent to 3/2 pounds

3/5 of a 1.5-pound

= 3/5 × 3/2 pounds

= 9/10 lbs of goldfish eaten in 5/6 hours

how long, in hours, would it take her to finish a 5-lb box of goldfish?

Find the ratio

9/10 lbs of goldfish : 5/6 hours = 5lbs of goldfish : t hours

9/10 ÷ 5/6 = 5 / t

Solve for t

9/10 × 6/5 = 5 / t

54 / 50 = 5 / t

Cross multiply

54 × t = 50 × 5

54t = 250

Divide both sides by 54

t = 250 / 54

= 4 34/54

= 4 17/27 hours

Therefore, it will take Larissa 4 17/27 hours to finish 5lbs of goldfish

The area between z = -1.30 and z = 1.50 is B. 0.0968.

To get the area between z = -1.30 and z = 1.50, we need to subtract the area to the left of z = -1.30 from the area to the left of z = 1.50.
The area to the left of z = -1.30 is the same as the area to the right of z = 1.30, which is 1 - 0.4032 = 0.5968.
The area to the left of z = 1.50 is 0.4332.
Therefore, the area between z = -1.30 and z = 1.50 is 0.4332 - 0.5968 = 0.0968.

John's savings amount as a function of time is S(t) = $24,000 / 25. Initially, he needs to save $24,000 for a new car. After the first month, he has saved $1,000. The savings amount is directly proportional to the time elapsed. The constant of proportionality is 1/24. Thus, John's savings amount can be determined based on the remaining amount he needs to save.

John's savings amount can be represented as a function of time and is proportional to the amount he still needs to save. Let's denote the amount John needs to save as N(t) at time t, and his savings amount as S(t) at time t. Initially, John needs to save $24,000, so we have N(0) = $24,000.

We know that John has saved $1,000 after the first month, which means S(1) = $1,000. Since his savings amount is proportional to the amount he still needs to save, we can write the proportionality as:

S(t) = k * N(t)

where k is a constant of proportionality.

We need to find the value of k to determine John's savings amount at any given time.

Using the initial values, we can substitute t = 0 and t = 1 into the equation above:

S(0) = k * N(0)  =>  $1,000 = k * $24,000  =>  k = 1/24

Now we have the value of k, and we can write John's savings amount as a function of time:

S(t) = (1/24) * N(t)

Since John's savings amount is proportional to the amount he still needs to save, we can express the amount he still needs to save at time t as:

N(t) = $24,000 - S(t)

Substituting the expression for N(t) into the equation for S(t), we get:

S(t) = (1/24) * ($24,000 - S(t))

Simplifying the equation, we have:

24S(t) = $24,000 - S(t)

25S(t) = $24,000

S(t) = $24,000 / 25

Therefore, John's savings amount at any given time t is S(t) = $24,000 / 25.

For a study to allow conclusions about causality, researchers must randomly assign participants to conditions and manipulate the independent variable.

For a study to establish causality, there are several key requirements that researchers must adhere to:

Randomly assign participants to conditions:

Random assignment is crucial to ensure that participants have an equal chance of being assigned to different experimental conditions.

By randomly assigning participants, researchers can minimize the potential confounding effects of individual differences and distribute them evenly across groups.

This helps establish a causal link between the independent variable (manipulated condition) and the dependent variable (outcome).

Manipulate the independent variable:

Researchers must deliberately manipulate the independent variable, which is the factor believed to have a causal effect on the dependent variable.

By manipulating the independent variable and observing the resulting changes in the dependent variable, researchers can infer causality.

The manipulation allows for comparisons between different conditions, enabling researchers to draw conclusions about the causal relationship between variables.

Gather a random sample of participants:

It is important to collect a random sample of participants from the target population.

Random sampling helps ensure that the sample is representative of the larger population, increasing the generalizability of the study's findings.

A random sample reduces the risk of sampling bias, where the characteristics of the sample deviate significantly from those of the population.

Control extraneous variables:

To establish causality, researchers must control for extraneous variables, factors other than the independent variable that could influence the dependent variable.

This can be achieved through techniques like random assignment, matching participants on relevant characteristics, or using statistical methods such as regression analysis to account for these variables.

It is worth noting that making sure participants are all of the same socio-economic status is not a requirement for establishing causality.

In fact, including participants with diverse socio-economic backgrounds can enhance the external validity and generalizability of the study's findings.

The focus should be on minimizing confounding variables and establishing a clear causal relationship between the independent and dependent variables.

The possibility that something will occur, prior measures, and conventional objective measurements all influence the likelihood that something will occur.

What is probability and what types are there in total?

The study of probability is a field of mathematics that determines the probability of an event occurring, which is represented by a number between 1 and 0. When an event has a probability of 1, it can be said to be a certainty. For instance, if the coin lands flat, the likelihood that it will come up  "heads or  tails" is 1. There are no other possible outcomes. A probability of .5 indicates that there is an equal chance that an event will occur or not.

Probability can be quantitatively represented in the simplest form as follows: the total number of possible outcomes multiplied by the ratio of the number of occurrences of a targeted event divided by the sum of the occurrences and failures of occurrences:

P(a) = P(a)/[P(a) + P(b)]

As a result, the floor's perimeter in the size illustration is 38,016 inches.

The perimeter of an object is the space surrounding its border. Find the perimeter of different forms by combining the lengths of their sides.

We can start by finding the scale factor that relates the length of the actual floor to the length of the scale drawing.

The length of the actual floor is 32 feet = 384 inches (since there are 12 inches in a foot).

The length of the scale drawing is given as 16 inches.

Therefore, the scale factor is:

384 inches / 16 inches = 24

This means that one inch on the scale drawing represents 24 inches in the actual floor.

To find the perimeter of the floor in the scale drawing, we need to multiply the perimeter of the actual floor by the scale factor.

The perimeter of the actual floor is:

2(32 feet) + 2(34 feet) = 64 feet + 68 feet = 132 feet

Converting to inches, we get:

132 feet x 12 inches/foot = 1584 inches

Multiplying by the scale factor of 24, we get:

1584 inches x 24 = 38,016 inches

The parameters of the SDEs are learned by maximizing the likelihood of the data under the model, which can be achieved by minimizing a loss function that is derived from the score function.

One advantage of this approach is that it can be used to model complex, high-dimensional data distributions, such as images or videos, that are difficult to model using traditional parametric methods. Another advantage is that it can handle missing data or irregularly sampled data, which can be common in many real-world datasets.
