Is it just asking me a congruence theorem, does it want me to say what’s congruent to what, or does it just want the angles and or sides?

The difference between the two items are depends on sample size, the method of counting, or the criteria for classification can all impact the percentage calculation.

Percentage is a measure of the proportion of one value to another expressed as a fraction of 100. For example, if there are 100 apples, and 25 of them are red, then the percentage of red apples is 25%. Similarly, if there are 200 bananas, and 50 of them are ripe, then the percentage of ripe bananas is also 25%.

However, the context in which these percentages are calculated can be different. For instance, the way in which the 25% of red apples was calculated could be different from how the 25% of ripe bananas was calculated.

To illustrate this, let's consider an example. Suppose there are two cities, A and B, with populations of 10,000 and 5,000, respectively. In city A, 2,500 people have blue eyes, while in city B, 1,250 people have blue eyes. At first glance, it may seem that the percentage of people with blue eyes is the same in both cities, at 25%.

However, if we look closer, we can see that the actual number of people with blue eyes is different between the two cities. City A has twice as many people with blue eyes as city B, even though the percentage is the same.

Answer: The null hypothesis for this scenario is that the proportion of readers who own a personal computer is 0.51 or less:

H0: p <= 0.51

The alternative hypothesis is that the proportion of readers who own a personal computer is greater than 0.51:

Ha: p > 0.51

To test this hypothesis, we would need to collect a random sample of readers and determine the proportion of readers who own a personal computer in the sample. We could then use a one-sample proportion test to determine whether the proportion in the sample is significantly different from the null hypothesis value of 0.51. If the p-value is less than 0.05, we would reject the null hypothesis and conclude that there is sufficient evidence to substantiate the publisher's claim that more than 51% of their readers own a personal computer. If the p-value is greater than or equal to 0.05, we would fail to reject the null hypothesis and conclude that there is not sufficient evidence to substantiate the publisher's claim.

On solving the provided question we can say that equation  As a result, the expedition can go 476 kilometres before running out of fuel.

A mathematical equation is a formula that connects two statements and denotes equivalence with the equals symbol (=). An equation is a mathematical statement that shows the equality of two mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the variables 3x + 5 and 14. A mathematical formula describes the connection between the two sentences that occur on opposite sides of a letter. The symbol and the single variable are frequently the same. As in 2x - 4 equals 2, for instance.

To calculate how far the expedition can travel before running out of gas, apply the following formula:

Miles = (Gallons of gas) x (Miles per gallon)

Plugging in the given values, we get:

Miles = 28 gallons x 17 mpg

Miles = 476 miles

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.

P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

We can determine if events A and B are independent or dependent by comparing the probability of both events occurring together with the product of their individual probabilities.

P(A and B) = 1/7

P(A) = 2/3

P(B) = 3/7

If A and B are independent events, then P(A and B) = P(A) * P(B). However, in this case, P(A and B) is not equal to P(A) * P(B):

P(A) * P(B) = (2/3) * (3/7) = 2/7

Since P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

Events A and B are dependent since the probability of their intersection is not equal to the product of their individual probabilities. Specifically, P(A and B) = 1/7 while P(A)*P(B) = 2/7.

Therefore, P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

A statement 'The function f(x)=log0. 75x is decreasing' is True.

We know that a function, y = f(x) is a decreasing function when (dy/dx) ≤ 0 for all such values of interval (a, b).

Consider a function  f(x)=log(0.75^x)

We write a function f(x) as,

f(x) = log(0.75^x)

f(x) = log[(3/x)^x]

f(x) = log([tex]\frac{3^x}{4^x}[/tex])

Now we find the derivative of above function with respect to x.

f'(x) = d/dx [ log([tex]\frac{3^x}{4^x}[/tex])]

f'(x) = [tex]1/(\frac{3^x}{4^x} )[/tex] [d/dx ([tex]\frac{3^x}{4^x}[/tex])]

f'(x) = [tex](\frac{4^x}{3^x})[\frac{4^x[3^xlog(3)]-3^x[4^xlog(4)]}{4^{2x}} ][/tex]

f'(x) = log(3) - log(4)

Answer: The compound interest is $409.49, and the total amount after one year is $3,665.49.

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where:

P = the principal (in this case, $3,256)

r = the annual interest rate (100%, or 1 as a decimal)

n = the number of times the interest is compounded per year (4, since it's compounded quarterly)

t = the number of years (1)

Plugging in the values we know, we get:

A = $3,256(1 + 1/4)^(4*1)

A = $3,256(1.25)^4

A = $3,665.49 (rounded to the nearest cent)

To find the compound interest, we can subtract the principal from the total amount:

Compound interest = $3,665.49 - $3,256 = $409.49

Therefore, the compound interest is $409.49, and the total amount after one year is $3,665.49.

Answer:

To find the hypotenuse (c) of a right triangle with a height of 4 units and a base of 12 units, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The Pythagorean Theorem can be expressed as:

c^2 = a^2 + b^2

where c is the hypotenuse, and a and b are the lengths of the other two sides.

In this case, the height (a) is 4 units and the base (b) is 12 units.

Plugging these values into the Pythagorean Theorem equation, we get:

c^2 = 4^2 + 12^2

c^2 = 16 + 144

c^2 = 160

Taking the square root of both sides to solve for c, we get:

√(c^2) = √160

c = √160

So, the hypotenuse (c) of the triangle is √160
