Answer:

a = 25 m²

b = 5 m

c = 7.94 m

d = 35.73 m²

Code:    H I A B

Step-by-step explanation:

Formulae

Pythagoras’ Theorem:    \(a^2+b^2=c^2\)

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Area of a square = x²  (where x is the side length)

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

Assuming that all the quadrilaterals are squares.

Side length of blue square with area 16 m² = √16 = 4 m

Side length of yellow square with area 9 m² = √9 = 3 m

Use Pythagoras' Theorem to find the length of b:

\(\implies 4^2+3^2=b^2\)

\(\implies b^2=25\)

\(\implies b=\sqrt{25}\)

\(\implies b=5\: \sf m\)

Now we have found length b, we can find area a:

\(\textsf{Area a}=b^2=5^2=25\: \sf m^2\)

Side length of purple square with area 144 m² = √144 = 12 m

Side length of green square with area 81 m² = √81 = 9 m

Use Pythagoras' Theorem to find the length of c:

\(\implies 9^2+c^2=12^2\)

\(\implies c^2=63\)

\(\implies c=\sqrt{63}\)

\(\implies c=3\sqrt{7}\)

\(\implies c=7.94\: \textsf{(nearest hundredth)}\)

Now we have found length d, we can find area d:

\(\textsf{Area d}=\dfrac{1}{2}(9)(7.94)=35.73\: \sf m^2\)

The correct answer is 90%, because as the level of confidence decreases, the corresponding critical value of z (z-score) also decreases, resulting in a wider confidence interval. Option B is correct.

A confidence interval is a range of values that is likely to contain the true population parameter with a certain degree of confidence. The width of the confidence interval depends on several factors, including the sample size, the standard deviation of the population, and the level of confidence.

Assuming all other factors remain constant, decreasing the level of confidence from 99% to 90% would result in a lower critical value of z (z-score) and a wider confidence interval. This is because a lower level of confidence allows for a greater margin of error, meaning that we are willing to accept a wider range of values as being plausible for the true population parameter.

Conversely, increasing the level of confidence from 90% to 99% would result in a higher critical value of z and a narrower confidence interval, because a higher level of confidence requires a higher degree of precision and accuracy in estimating the true population parameter.

Hence, B. 90%, because as the level of confidence​ decreases, z Subscript czc decreases is the correct option.

The solution to the problem is the simplified expression: 5x³ - x² - 3x + 13.

To solve the given problem, you need to simplify and combine like terms. Start by adding the coefficients of the same degree terms.

(3x³ - x² + 4) + (2x³ - 3x + 9)

Combine the like terms:

(3x³ + 2x³) + (-x²) + (-3x) + (4 + 9)

Simplify further:

5x³ - x² - 3x + 13

In this expression, the highest power of x is ³, and the corresponding coefficient is 5. The term -x² represents the square term, -3x represents the linear term, and 13 is the constant term. The simplified expression does not have any like terms left to combine, so this is the final solution.

2x - y - 8 = 0

Step-by-step explanation:

x1 = 2

y1 = -4

m = 2

using the formula,

y-y1 = m(x-x1)

y+4 = 2(x-2)

y+4 = 2x - 4

y-2x+4+4 = 0

y-2x+8 = 0 (×-1)

2x - y - 8 = 0

Therefore the equation of the line is;

Using distributive property, the simplified form of (5x - 7)(4x + 1) is 20x^2- 23x - 7.

In the given question we have to solve the given expression.

The given expression is (5x - 7)(4x + 1).

To simplify the given expression we use the distributive property.

According to property; a(b+c) = ab+bc

Now simplifying the expression;

(5x - 7)(4x + 1)=5x(4x + 1) - 7(4x + 1)

(5x - 7)(4x + 1)=(5x*4x + 5x*1) - (7*4x + 7*1)

(5x - 7)(4x + 1)=(20x^2 + 5x) - (28x + 7)

Simplifying

(5x - 7)(4x + 1)=20x^2+5x -28x - 7

(5x - 7)(4x + 1)=20x^2- 23x - 7

The simplified form of (5x - 7)(4x + 1) is 20x^2- 23x - 7.

The null hypothesis (H0) proposed by the friend is H0: p^ = 0.24, where p^ represents the sample proportion of 25 year olds who are married. The alternative hypothesis (Ha) is Hα: p^ ≠ 0.24.

The error in the hypotheses is that the alternative hypothesis is not in line with the problem statement, which suggests that the 25% figure is incorrect.

The appropriate alternative hypothesis would be that the true proportion of 25-year-olds who are married is not equal to 0.25. Therefore, the correct alternative hypothesis would be Ha: p^ ≠ 0.25.

In summary, the correct set of hypotheses for this problem would be:

H0: p^ = 0.25 (Null hypothesis)

Ha: p^ ≠ 0.25 (Alternative hypothesis)

learn ur multiplication!!!!!! and it'll be easy as cake!

Answer/step-by-step explanation:

We know that during their first year, the company caught 95,000 fish, and the amount of fish caught decreased 4% each year. First, let's calculate 4% of 95,000, by doing the equation: 95,000 x 0.04 = 3,800

So, each year, the company catches 3,800 less fish.

In order to find out how many fish the company caught in ten years, we need to multiply 3,800 x 10 and then subtract it from 95,000. Then we need to multiply that number by 10.

3,800 x 10 = 38,000

95,000 - 38,000 = 57,000 x 10 = 570,000.

Therefore, the company caught a total of 57,000 fish in the first ten years.

The three major categories of determinants that influence building energy use are:

1. Building design and construction: The design and construction of a building have a significant impact on its energy consumption. Factors such as building orientation, insulation, glazing, and ventilation systems can affect the amount of energy required for heating, cooling, and lighting. For example, a well-insulated building with energy-efficient windows and airtight construction will require less energy for heating and cooling compared to a poorly insulated building with drafty windows.

2. Occupant behavior: How occupants use and interact with the building can greatly influence energy consumption. Actions such as adjusting the thermostat, using natural daylight instead of artificial lighting, and turning off lights and appliances when not in use can help reduce energy usage. For instance, setting the thermostat to a moderate temperature and utilizing natural ventilation during favorable weather conditions can significantly decrease energy demand.

3. Building systems and equipment: The efficiency of the building's systems and equipment also plays a crucial role in energy consumption. This includes heating, ventilation, and air conditioning (HVAC) systems, lighting fixtures, and appliances. Energy-efficient technologies like programmable thermostats, LED lighting, and energy-star-rated appliances can minimize energy consumption. Upgrading older equipment to more efficient models can result in substantial energy savings.
