What is right-angled triangle?

Triangle that has one angle 90 degree is called right-angled. In case of a right triangle the square of the largest side length is equal of the sum of the square of the other two side length.

SA triangle has three side length 11-unit, 60 unit and 61 unit respectively.

The triangle is verified as a right-angled triangle by Pythagorean theorem.

And as the properties of a Pythagorean theorem the sum of the square of two side length is equal to the square of the largest side length.

if we say, one side length, a = 11 unit

             second side length, b = 60 unit

    the largest side length, c

now we will check,  

√(11²+60²) = c² =√3721 = 61

the value of c = 61 unit.

hence, the SA is right-angled triangle.

Answer:

y = \(\frac{1}{3}\) x - 10

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = \(\frac{1}{3}\) , then

y = \(\frac{1}{3}\) x + c ← is the partial equation

to find c substitute (12, - 6 ) into the partial equation

- 6 = \(\frac{1}{3}\) (12) + c = 4 + c ( subtract 4 from both sides )

- 10 = c

y = \(\frac{1}{3}\) x - 10 ← equation of line

Answer:

£15.6

Step-by-step explanation:

Method 1:

You are trying to find 30% of £52.

Therefore:

\(\frac{30}{100} * 52 = \frac{30 * 52}{100}\)

If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.

So, the answer is £15.6.

Method 2:

You can solve 30% of £52 by using an algebra equation.

By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.

Now, in order to write the equation, you will have to include 0.3 and 52.

The equation is:

0.3 * 52 = x

Once you multiply, you will find that the answer is £15.6.

The type of error that explains the variability in the results between groups is "random error."Explanation:Random error is the variability between the groups' results due to the imprecision of the measuring instrument or technique.

It is caused by minor differences in the experimental conditions that are unpredictable and can not be controlled or accounted for in the experiment. Random error can lead to imprecise results that fluctuate from the main answer, which means that it is not biased towards one particular direction.The other type of error that is commonly known is "systematic error" which is characterized by consistent errors that occur in a specific direction due to the method or instrument used.

Systematic error is due to the inaccuracy of the measuring instrument or incorrect experimental design, and it can affect the accuracy of the main answer. Mistakes or human errors, on the other hand, are due to human error, such as incorrect calculations or transcriptions, and are not part of the sources of errors.

The function f(x) = x³ - 6x² + 12x - 11 has a domain of all real numbers. The critical points are found by taking the derivative and setting it equal to zero, resulting in x = -1 and x = 2.

The function is not symmetric about the y-axis or the origin. The relative extrema are a local minimum at x = -1 and a local maximum at x = 2. The function increases on the intervals (-∞, -1) and (2, ∞) and decreases on the interval (-1, 2). The inflection point is at x = 0. The function is concave up on the intervals (-∞, 0) and (2, ∞) and concave down on the interval (0, 2). There are no vertical or horizontal asymptotes. The graph of the function exhibits these characteristics.

The domain of the function f(x) = x³ - 6x² + 12x - 11 is all real numbers since there are no restrictions on the input values.

To find the critical points, we take the derivative of f(x) and set it equal to zero. The derivative is f'(x) = 3x² - 12x + 12. Setting f'(x) = 0, we find x = -1 and x = 2 as the critical points.

The function is not symmetric about the y-axis or the origin because the exponents of x are odd.

By analyzing the sign of the derivative, we determine that f(x) increases on the intervals (-∞, -1) and (2, ∞), and decreases on the interval (-1, 2). Thus, the relative extrema occur at x = -1 (local minimum) and x = 2 (local maximum).

To find the inflection point, we take the second derivative of f(x). The second derivative is f''(x) = 6x - 12. Setting f''(x) = 0, we find x = 0 as the inflection point.

By examining the sign of the second derivative, we determine that f(x) is concave up on the intervals (-∞, 0) and (2, ∞), and concave down on the interval (0, 2).

There are no vertical or horizontal asymptotes in the function.

Combining all these characteristics, we can sketch the graph of the function f(x) = x³ - 6x² + 12x - 11, showing the domain, critical points, symmetry, relative extrema, regions of increase/decrease, inflection points, concavity, and absence of asymptotes.

Esther missed including the surface area of the square sides of the pyramid. The correct surface area is found by adding the surface area of the four triangular faces, base, and sides. The total surface area is 104cm².

Esther's error was that she only considered the surface area of the triangular faces and the base of the pyramid. She failed to include the surface area of the pyramid's square sides.

To find the correct surface area of the pyramid, we need to add the surface area of the four triangular faces and the surface area of the square base and sides. The surface area of the square base is 4² = 16cm², and the surface area of each triangular face is (1/2)bh = (1/2)(4)(7) = 14cm². The surface area of each square side is 4 x 4 = 16cm².

Therefore, the correct surface area of the square pyramid is:

4 x 14cm² (for the four triangular faces) + 16cm² (for the base) + 4 x 16cm² (for the four square sides) = 104cm².

1. The probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5. 2. For Option a), Option c), Option d) the event not happening. Probabilities must fall between 0 and 1, inclusive, and cannot be negative or greater than 1.

1. The probability of obtaining an even number when rolling a fair die can be determined by dividing the number of favorable outcomes (even numbers) by the total number of possible outcomes (all numbers on the die). In the case of a standard six-sided die, there are three even numbers (2, 4, and 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, and 6). Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.

2. In terms of the numbers provided, the one that cannot be a probability is c) 1.001. Probabilities always range between 0 and 1, inclusive. A probability of 1 means that an event is certain to occur, while a probability of 0 means that an event will not occur. Any value greater than 1, such as 1.001, is not a valid probability because it implies that the event is more certain than certain. It is important to note that probabilities cannot exceed 1 or be negative.

In probability theory, a probability is a measure of the likelihood of an event occurring. It is always expressed as a value between 0 and 1, inclusive. A probability of 0 means that the event is impossible and will not occur, while a probability of 1 indicates that the event is certain to occur. Intermediate values between 0 and 1 represent different levels of likelihood.

Option a) −0.00001 cannot be a probability because probabilities cannot be negative. Negative values imply the presence of an event's complement (the event not happening) rather than the event itself.

Option b) 0.5 is a valid probability, representing an equal chance of an event occurring or not occurring. It indicates that there is a 50% chance of the event happening.

Option d) 0 is also a valid probability, indicating that the event is impossible and will not happen.

Option e) 1 is a valid probability, denoting that the event is certain to occur. The probability of an event occurring is 100%.

Option f) 20% is a valid probability, but it can also be expressed as the decimal fraction 0.2. It represents a 20% chance or a 1 in 5 likelihood of the event happening.

In conclusion, probabilities must fall between 0 and 1, inclusive, and cannot be negative or greater than 1.

The solution to the equation\(4^5 - 3x - \frac{1}{256 }\)is x = 128.

To solve the equation \(4^5 - 3x - \frac{1}{256}\) = 0, we need to isolate the variable x. We start by simplifying the expression \(4^5\), which is equal to 1024.

The equation then becomes 1024 - 3x - \(\frac{1}{256}\) = 0.

To eliminate the fraction, we can multiply the entire equation by 256, resulting in 256(1024) - 256(3x) - 1 = 0.

This simplifies to 262,144 - 768x - 1 = 0.

Combining like terms, we have -768x + 262,143 = 0. To isolate x, we subtract 262,143 from both sides, giving us -768x = -262,143.

Finally, we solve for x by dividing both sides by -768, yielding x = 128.

The condition that has not been met for conducting a z-test for a proportion is (b) The sample size is less than 10% of the population size.

In order to conduct a z-test for a proportion, certain conditions need to be met. The first condition is that the data should be a random sample from the population of interest (condition a), which has been met in this case as the students entering the room can be considered a random sample of the statistics class.

The third condition is that the product of the population proportion (p) and the sample size (n) should be greater than or equal to 10, and the product of the complement of the population proportion (1-p) and the sample size (n) should also be greater than or equal to 10 (condition c). However, the second condition (b) has not been met in this scenario. The sample size of 5 students is not less than 10% of the population size, which is 30.

Therefore, the sample size is not large enough to meet this condition. Consequently, the correct answer is (e) More than one condition is violated, as the other conditions are still satisfied.

Answer:

A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7.

Step-by-step explanation:

We have the equation:

|8 - 2*p| = 6

Remember that the equation:

|f(x)| = A

with A > 0

means that:

f(x) = A

or

f(x) = -A

Then for our case, we can rewrite:

|8 - 2*p| = 6

as:

(8 - 2*p) = 6

or

(8 - 2*p) = -6

Now we can solve these two equations to find the two possible values of p.

From the first one, we get:

8 - 2*p = 6

8 - 6 = 2*p

2 = 2*p

2/2 = p = 1

so one solution is  p = 1

Now from the other equation, we can get the other solution:

(8 -2*p) = -6

8 - 2*p = -6

8 + 6 = 2*p

14 = 2*p

14/2 = p = 7

So the two solutions are p = 1 and p = 7

Then the correct option is:

"A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7."

The ratio of green marbles to all marbles is 39:47, or approximately 8:9.

6 blue : 47 total = 6:47

2 red : 47 total = 2:47

green : 47 total = (47-6-2):47 = 39:47

The ratio of green marbles to all marbles in the jar is 39:47. This can be determined by taking the number of green marbles (39) and dividing it by the total number of marbles in the jar (47). This results in a ratio of approximately 8:9. It is important to note that this ratio does not take into account the other colors of marbles in the jar, only the green ones. To find out the ratio of all marbles in the jar, including blue and red, we must first calculate the ratio of blue and red marbles to the total. This can be done by taking the number of blue marbles (6) and dividing it by the total number of marbles (47), which gives us a ratio of 6:47. Similarly, the ratio of red marbles to the total can be calculated by taking the number of red marbles (2) and dividing it by the total number of marbles (47), giving us a ratio of 2:47. Finally, we can calculate the ratio of all marbles in the jar by adding the ratios of blue and red marbles to the ratio of green marbles, which gives us a ratio of (39+6+2):47, or 39:47.
