Given statement "3-2 Roof area can be broken down into three basic shapes: rectangle, triangle, and trapezoid"

Given statement is True.
Because: When calculating the roof area, we can generally break it down into three basic shapes:

The term "roof area" typically refers to the total surface area of a roof. This can be calculated by measuring the length and width of each section of the roof, and multiplying those measurements together to get the area of each section.

Then, the areas of all the sections can be added together to get the total roof area.

It's important to accurately measure the roof area when planning for construction or repairs, as it will affect the amount of materials needed and the cost of the project.

Roof area can also be used to calculate the amount of insulation needed or to estimate the potential energy savings of installing solar panels.

Rectangle:

A four-sided polygon with opposite sides parallel and equal in length.
Triangle:

A three-sided polygon with three vertices and three angles.
Trapezoid:

A four-sided polygon with one pair of parallel sides.
By dividing a roof's surface into these shapes, you can calculate the total area more easily.

Hence statement is True.

The number of oranges that are expected to weigh more than 4 oz is:

1400 - (1400 × 0.0228)≈ 1368.

The mean weight of the oranges growing in an orchard is 8 oz and standard deviation is 2 oz, the distribution of the weight of oranges can be represented as normal distribution.

From the batch of 1400 oranges, the number of oranges is expected to weigh more than 4 oz can be found using the formula for the Z-score of a given data point.

\(z = (x - μ) / σ\)

Wherez is the Z-score of the given data point x is the data point

μ is the mean weight of the oranges

σ is the standard deviation

Now, let's plug in the given values.

\(z = (4 - 8) / 2= -2\)

The area under the standard normal distribution curve to the left of a Z-score of -2 can be found using the standard normal distribution table. It is 0.0228. This means that 0.0228 of the oranges in the batch are expected to weigh less than 4 oz.

The recursive formula that represents the same sequence of numbers as the explicit formula an = 3n + 4 is an = an-1 + 3, with the initial term a1 = 7.

A recursive formula defines a sequence by expressing each term in terms of previous terms. In this case, the explicit formula an = 3n + 4 gives us a direct expression for each term in the sequence.

To find the corresponding recursive formula, we need to express each term in terms of the previous term(s). In this sequence, each term is obtained by adding 3 to the previous term. Therefore, the recursive formula is an = an-1 + 3.

To complete the recursive formula, we also need to specify the initial term, a1. We can find the value of a1 by substituting n = 1 into the explicit formula:

a1 = 3(1) + 4 = 7

Hence, the complete recursive formula for the sequence is an = an-1 + 3, with the initial term a1 = 7. This recursive formula will generate the same sequence of numbers as the given explicit formula.

just going by the trend this makes the most sense

The following equation O y = x² + 1 can be a possible answer to the given question. Hence, the correct option is "y=z² - 1".

In the given question, we are given with 4 different equations. We need to select the equation which could be possible. We can check the options one by one . Option 1: O y = x² + 1Option 2: y=z² - 1Option 3: y = (x - 1)²

Now, we can check the first option y = x² + 1. Let's check whether the given option can be possible or not.

If we see the equation y = x² + 1, it is a second-degree equation, which is in the form of a quadratic equation.

Hence, it could be possible. Therefore, option 1 could be the equation.

Next, If we see the equation y = z² - 1, we can understand that it is also a second-degree equation. Hence, it could be possible.

Therefore, option 2 could be the equation. Let's check the third option.

If we see the equation y = (x - 1)², we can understand that it is also a second-degree equation.

Therefore, option 3 could be the equation. Finally, we have the option 4, which is 22.

We can understand that 22 is a number, not an equation.

Hence, option 4 is not an equation.

In conclusion, we have checked all the given options, and we can see that all the options except option 4 could be possible.

Hence, the correct option is "y=z² - 1".

The ratio of false positives to true positives is 8 over 54.

According to the Question

Results of a strep throat test performed on a sample of 400 ill people are displayed in the table's data. People who have the flu and those who don't are separated into two categories. The patients are then separated into groups based on whether they tested positive or negative for strep throat within each of these categories.

We must first define what a true positive and a false positive are in order to calculate the ratio of false positives to true positives. A patient who tests positive for strep throat but does not actually have the illness is said to have a false positive. The 8% of patients in this instance who tested positive for strep throat but did not have the flu would fall under that category. A patient who tests positive for strep throat and truly has the illness is said to have a true positive. That would be the 54% of patients who tested positive for both the flu and strep throat in this instance.

We divide the percentage of false positives (8%) by the percentage of true positives (54%), which gives us the ratio of false positives to true positives.

As a result, the ratio becomes 8% / 54%, or 8/54.

It's critical to remember that this ratio is dependent on the sample and test performed and may not be the same for different populations or testing methodologies.

Answer:

like:-

1/9x20 = 2 2/9

1/9-20 = 19 8/9

Step-by-step explanation:

Answer: The constant rate change would be \(\frac{1}{9}\).

Step-by-step explanation: The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval: f (x) = \(x^{2}\) , [2,3]

Write y = \(\frac{1}{9}\)x - 20 as a function which is f (x) = \(\frac{1}{9}\)x - 20

Consider the difference quotient formula which is \(\frac{f (x +h) - f (x) }{h}\).

Find the components of the definition. \(\frac{f (x+h) = \frac{h}{9} + \frac{x}{9} - 20}\)simplify then it would be \(\frac{f (x) = \frac{x}{9} - 20 }\).

Lastly plug in all the components.

\(\frac{f (x + h) - f (x)}{h} = \frac{\frac{h}{9} +\frac{x}{9} - 20 - (\frac{x}{9} - 20) }{h}\)

After solving all this the answer would be \(\frac{1}{9}\)

Answer:

x and y are proportional. Two quantities are proportional if there is a constant ratio between them. In this case, the ratio between y and x is always 16:

4/0.25=16

8/0.5=16

12/0.75=16

Since the ratio between y and x is always the same, x and y are proportional.

Answer:

160 in ^2

Step-by-step explanation:

First we need to find the area of each shape and add them together

1. Triangles:

The formula for a triangle is (base x height)/2, so we can replace them as (5 * 4)/2 * 2( Because there are two triangles), so therefore the two triangles will add up to 20 inches

2. The Rectangles

The Big Rectangle:

The big rectangle is just l x w or 5 * 20 which is 100

The small rectangle:

To find the width of the small rectangle you have to do 20 - (5 + 5) because we are not including the triangles. 20 - (5 +  5) = 10, so that would be 10 * 4 = 40.

3.Add them together

20 + 100 + 40 = 160 inches ^2

The statistical model is not good, and this is true for a negatively skewed curve.

It is a statistical term implies that a curve is skewed at the left side.

In a statistical data for a certain distribution, we can get a negatively skewed curve when most of the data values are located on the right side of the distribution graph. The high concentration of values on the right side of distribution curve forms a long tail in the negative direction.

In general, negatively skewed curve is not good because it expresses the tendency of left tail events. Negatively skewed curves indicate a poor return from an investment. That means a person might be earn lower or no profit from his business. In case of an exam scores, negative skewed data value implies the question was too easy to perform better than usual.

In a word, left skewed or negatively skewed curve or data values inform us to be aware about the current statistical model and inspire us to take proper steps for wellbeing.

Mutually exclusive events are those events that do not occur at the same time. For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.

Examples of mutually exclusive events are:

When a coin is tossed, getting heads and tails are mutually exclusive. Because the probability of getting both heads and tails is 0.

In a six-sided die, the events "2" and "5" are mutually exclusive. We cannot get events 2 and 5 at the same time with one die.
