The required answer to the subtraction problem 83,456 - 728.88 is, 82,727.12

Subtraction is mathematical terminology that helps and elaborates the decrease in the original value by some value.

Here,
To perform the subtraction, you line up the decimal points and subtract the digits in each place value starting from the right. In this case, you subtract 8 from 6, which requires borrowing 1 from the digit to the left, giving you 16 - 8 = 8 in the one's place. You then subtract 2 from 5, giving you 3 in the tenth place. Continuing this process, you get the result of 82,727.12.

Thus, the answer to the subtraction problem 83,456 - 728.88 is, 82,727.12

Answer:

Answer is 6 because line are parallel

To answer this question, we need to know the median and upper quartile of the data set. Once we have these values, we can determine what percentage of the data falls to the right of the median and to the left of the upper quartile.
Let's say the median of the data set is 50 and the upper quartile is 75. To find the percentage of measurements to the right of the median, we need to look at the data values that are greater than 50 and divide that number by the total number of measurements. Let's say there are 40 data values greater than 50 and a total of 100 measurements.

Then, the percentage of measurements to the right of the median would be:

(40/100) x 100% = 40%

To find the percentage of measurements to the left of the upper quartile, we need to look at the data values that are less than or equal to 75 and divide that number by the total number of measurements. Let's say there are 60 data values less than or equal to 75 and a total of 100 measurements. Then, the percentage of measurements to the left of the upper quartile would be:

(60/100) x 100% = 60%


Your answer:
1. 40% of the measurements lie to the right of the median.
2. 60% of the measurements lie to the left of the upper quartile (Q3).

a. Regression equation: The regression equation for predicting yield of wheat from rainfall is:y = 14.757 + 5.958 xIt narrates that the predicted yield (y) of wheat in the county is equal to 14.757 plus 5.958 times the rainfall (x).

b. Scatter diagram:The scatter diagram with the regression line for the equation is shown below:

c. Predicting the average yield of wheat when the rainfall is 9 inches:

When the rainfall is 9 inches, we can use the regression equation to predict the average yield of wheat:

y = 14.757 + 5.958 (9) = 68.013

Therefore, the average yield of wheat is predicted to be approximately 68.013 when the rainfall is 9 inches.

d. Percentage of the total variation of wheat yield accounted for by differences in rainfall:

We can find the coefficient of determination (r2) to determine the percentage of the total variation of wheat yield accounted for by differences in rainfall:

r2 = SSR/SST = 23.575/34.8 ≈ 0.678 or 67.8%

Therefore, approximately 67.8% of the total variation of wheat yield is accounted for by differences in rainfall.

e. Correlation coefficient for this regression:

We can find the correlation coefficient (r) as the square root of r2:

r = √r2 = √0.678 ≈ 0.823

Therefore, the correlation coefficient for this regression is approximately 0.823.

While a common rule of thumb is to have a minimum sample size of 100 for continuous data to be statistically significant, the actual appropriate sample size may vary depending on the specific study design and research question. Option(D)

In statistics, the term "statistical significance" refers to whether an observed effect or relationship in the data is likely to be real and not just due to random chance. To determine statistical significance, we often perform hypothesis testing.

The sample size is a crucial factor in hypothesis testing. A larger sample size generally provides more reliable and precise estimates of population parameters and increases the statistical power of the test. With a larger sample size, even smaller effects or differences between groups can become statistically significant.

While there is no hard and fast rule for the minimum sample size to achieve statistical significance, a common guideline is to aim for at least 30 samples. This guideline is often used in the context of the Central Limit Theorem, which states that the sampling distribution of the sample mean becomes approximately normally distributed 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.

In practice, the appropriate sample size depends on various factors, including the nature of the data, the effect size being studied, the desired level of confidence, and the statistical test used. Researchers often conduct sample size calculations based on these factors before conducting their studies to ensure they have an adequate sample size to achieve meaningful results and detect significant effects if they exist.

Solve this problem using the golden ratio. Given the golden ratio (1 + √5) : 2 and the width of the door, we will find the height of the door.

Step 1: Write the ratio as a fraction.
The golden ratio can be written as a fraction: (1 + √5) / 2.

Step 2: Set up a proportion.
Let the height of the door be h. Then we can write the proportion:

height : width = (1 + √5) / 2
h / 36 = (1 + √5) / 2

Step 3: Solve for h.
To find the height of the door, we'll cross-multiply and solve for h:

h = 36 * (1 + √5) / 2

Step 4: Simplify the expression.
First, we'll distribute the 36:

h = (36 + 36√5) / 2

Next, we'll divide each term by 2:

h = (18 + 18√5)

So, the height of the door is 18 + 18√5 inches, which is in simplest radical form.

The given function is

The expression f(-16) means we have to evaluate the function when x = -16.

A hypothesis is a statement regarding a characteristic of one or more populations. The null hypothesis is a statement of no change, no effect, or no difference. The alternative hypothesis is a statement we are trying to find evidence to support.

Generally, the null hypothesis expresses that there is no change, no difference, no effect, and in another way, no relationship between the independent and dependent variables. Because we are hypothesizing that nothing is happening, then it is called the null hypothesis.

The null and alternative hypothesis are two conflicting claims which researchers weigh evidence for and against using a statistical test. Null hypothesis (H0) means there is no effect in the population. Meanwhile, alternative hypothesis (Ha or H1) means there is an effect in the population.

Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.

Simplifying

3x + 3 = 6x + -57

Reorder the terms:

3 + 3x = 6x + -57

Reorder the terms:

3 + 3x = -57 + 6x

Solving

3 + 3x = -57 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

3 + 3x + -6x = -57 + 6x + -6x

Combine like terms: 3x + -6x = -3x

3 + -3x = -57 + 6x + -6x

Combine like terms: 6x + -6x = 0

3 + -3x = -57 + 0

3 + -3x = -57

Add '-3' to each side of the equation.

3 + -3 + -3x = -57 + -3

Combine like terms: 3 + -3 = 0

0 + -3x = -57 + -3

-3x = -57 + -3

Combine like terms: -57 + -3 = -60

-3x = -60

Divide each side by '-3'.

x = 20

The last column evaluates to "T" in all rows. Therefore, the argument is valid since the conclusion always follows from the premises.

Let's assign symbols to represent the statements in the argument:

P: The boss snaps at you.

Q: You make a mistake.

R: The boss is irritable.

The argument can be symbolically represented as follows:

[(P ∧ Q) → R] ∧ ¬P → ¬R

To determine the validity of the argument, we can construct a truth table:

P | Q | R | (P ∧ Q) → R | ¬P | ¬R | [(P ∧ Q) → R] ∧ ¬P → ¬R

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

T | T | T |      T      |  F |  F |          T          |

T | T | F |      F      |  F |  T |          T          |

T | F | T |      T      |  F |  F |          T          |

T | F | F |      F      |  F |  T |          T          |

F | T | T |      T      |  T |  F |          F          |

F | T | F |      T      |  T |  T |          T          |

F | F | T |      T      |  T |  F |          F          |

F | F | F |      T      |  T |  T |          T          |

The last column represents the evaluation of the entire argument. If it is always true (T), the argument is valid; otherwise, it is invalid.

Looking at the truth table, we can see that the last column evaluates to "T" in all rows. Therefore, the argument is valid since the conclusion always follows from the premises.

Function transformation involves changing the form of a function

The function that represents the three hills is given as:

\(f(x) = (x - 1)(x -3)(x -4)\)

The above function represents the base equation.

When the function is then transformed, we have:

\(g(x) =- (x - 1)(x -3)(x -4) + 3\)

The first mistake in teen 1's design is that, the function f(x) has 3 x-intercepts

For the function to have three peaks, then the function must have three different vertices

A function with three x intercepts will have three zeros.

However, these three zeros does not mean the function has three peaks i.e. three vertices

Also, the transformed function g(x) is simply a reflection of f(x) across the x-axis, and a vertical shift up by 3 units.

This also does not mean that the function has three peaks
