A triangle is a polygon with three sides and three angles. Types of triangles are isosceles. scalene, equilateral, acute, obtuse and right angled triangle.

A right angled triangle is a triangle in which one of the angles is 90 degrees. Trigonometric ratios show the relationship between the angles of a right angle triangle and its sides.

Let h represent the height of the house above water, hence using trigonometric ratios:

tan(26) = h / 531

h = 531 * tan(26)

h = 259 ft.

Step-by-step explanation:

A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.

If the mean is greater than the median, the histogram would be skewed to the right

If the mean is less than the median, the histogram would be skewed to the left.

The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left

A regular hexagon has 6 congruent sides.

The dimension of the rectangle is 8 inches by \(4\sqrt 3\) inches

Start by calculating the value of x using the following cosine ratio

\(\cos(60) = \frac{x}{4}\)

Make x the subject

\(x = 4 * \cos(60)\)

Evaluate cos(60)

\(x = 4 * 0.5\)

\(x = 2\)

So, the dimension of the rectangle is:

\(Length = 2x + 4\)

\(Width = 2x\sqrt 3\)

This gives

\(Length = 2 * 2 + 4\)

\(Length = 8\)

\(Width = 2 * 2\sqrt 3\)

\(Width = 4\sqrt 3\)

Hence, the dimension of the rectangle is 8 by \(4\sqrt 3\)

If the algorithm has a constant number of steps independent of the input size, s(n) remains the same when n is doubled.

Then the effect on the number of steps required, denoted as s(n), when the number of items being processed (n) is doubled will depend on the specific algorithm and its complexity.

Here are a few possibilities:

1. Constant Time Complexity (O(1)): If the algorithm has a constant time complexity, it means that the number of steps required remains the same, regardless of the input size. In this case, doubling n would not have any impact on s(n).

2. Linear Time Complexity (O(n)): If the algorithm has a linear time complexity, it means that the number of steps required is directly proportional to the input size. Doubling n would approximately double the number of steps as well. Thus, s(n) would increase in a linear manner.

3. Quadratic Time Complexity (O(n^2)): If the algorithm has a quadratic time complexity, it means that the number of steps required grows quadratically with the input size. When n is doubled, the number of steps would be approximately four times the original amount. Thus, s(n) would increase significantly.

4. Logarithmic Time Complexity (O(log n)): If the algorithm has logarithmic time complexity, doubling n would not have a substantial impact on the number of steps required. The increase in s(n) would be relatively small compared to the increase in n.

These are just a few examples, and there are various other complexities that algorithms can exhibit.

Each algorithm has its own time complexity, which determines how the number of steps required changes as the input size is doubled.

Step-by-step explanation:

The number of black beads is 42, the number of white beads is 12, and there are 30 more black beads than white beads.

Mabel has a total of 54 decorative beads, some are black, and some are white. The ratio of the number of black beads to the number of white beads is 7:2. We have to find how many more black beads than white beads.

Let the total number of black beads be 7x, and that of white beads be 2x, respectively.

So, according to the problem, 7x + 2x = 54⇒ 9x = 54⇒ x = 6

Hence, the total number of black beads = 7x = 7 × 6 = 42

And the total number of white beads = 2x = 2 × 6 = 12

Therefore, the required difference between the number of black beads and white beads is 42 - 12 = 30.

Therefore, there are 30 more black beads than white beads.

The value of x , y and z in the parallel line is 50 degrees.

When parallel lines are crossed by a transversal line, angle relationships are formed such as vertically opposite angles, alternate interior angles, alternate exterior angles, adjacent angles, corresponding angles etc.

Therefore, let's use the angle relationships to find the angle, x, y and z as follows:

Therefore,

x = 360 - 310(sum of angles in a point)

x = 50 degrees

Therefore,

x = y(alternate interior angles)

Alternate interior angles are congruent.

Hence,

y = 50 degrees

Therefore,

x = z(alternate interior angles)

z = 50 degrees.

The anticipated variability or widespread deviation of the means from MANY unique random samples is known Sampling distribution.

The standard deviation of this distribution, i.e. the standard deviation of sample means, is called the standard error. The standard error tells you how accurate the mean of any given sample from that population is likely to be compared to the true population mean.

What is the suggest variance and fashionable deviation of the sampling distribution of the pattern mean?

a) The area of the first circle is approximately 254.34 square inches

b) The area of the second circle is approximately 70650 square inches.

a) The area of a circle can be calculated using the formula A = πr², where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

For the first circle with a diameter of 18 inches, we can find the radius by dividing the diameter by 2:

r = 18/2 = 9 inches

Now we can calculate the area using the formula:

A = πr² = 3.14 x 9² = 254.34 square inches

Therefore, the area of the first circle is approximately 254.34 square inches.

b) For the second circle with a diameter of 25 feet, we need to convert the diameter to inches, since our formula uses radius in inches:

25 feet = 25 x 12 inches = 300 inches

Then we can find the radius by dividing by 2:

r = 300/2 = 150 inches

Now we can calculate the area using the formula:

A = πr² = 3.14 x 150² = 70650 square inches

Therefore, the area of the second circle is approximately 70650 square inches.

Note that the units for the second calculation are in square inches, not square feet, because we used the formula that requires radius in inches.

The critical value if the hypothesis is to be tested at the 0.05 level of significance is 1.96 . So, option C is the correct answer.

To test the hypothesis that Woof Chow has a market share of 25%, we need to conduct a hypothesis test with the null hypothesis that the true proportion of dog owners who use Woof Chow is 0.25, and the alternative hypothesis that the true proportion is not 0.25.

Since the sample size n is large (n = 100), we can use the normal distribution to perform this test. The critical value for a two-tailed test at the 0.05 level of significance is given by:

z_critical = ±1.96

This value corresponds to the 2.5th and 97.5th percentiles of the standard normal distribution. The critical value is ±1.96 because we want to be 95% confident that the true proportion of dog owners who use Woof Chow is within a certain range, and the 95% confidence interval corresponds to two standard deviations from the mean.

To determine whether or not to reject the null hypothesis, we would calculate a test statistic (z-score) based on the sample proportion, and compare it to the critical value. If the test statistic falls outside the critical value, we would reject the null hypothesis and conclude that Woof Chow does not have a market share of 25%.

The solution which we get for the given question is , x = 5/2 and y = 5/4 answer.

Isolating x,

2x = 9x - 14y

2x-9x = 9x-9x -14y

-7x = -14y

-7x/-7 = -14y/-7

x = 2y

Therefore substituting value of x on equation 2,

9(2y) = 40 - 14y

18y = 40 - 14y

18y+14y = 40 -14y+14y

32y = 40

32y/32 = 40/32

y = 5/4

Therefore , x = 10/4 = 5/2

as because x =2y.

Answer:

£500,000.00

Step-by-step explanation:

Principal = x

Saving rate  = 2% PA simple

Time = 5 years

Final amount = £550,000

Principal amount is £500,000

Answer:

\(\huge \boxed{{x=500,000}}\)

Step-by-step explanation:

\(A=P(1+rt)\)

\(A\) = amount   ⇒  550000

\(P\) = principal amount   ⇒  x

\(r\) = rate   ⇒  2%

\(t\) = time   ⇒  5

\(\displaystyle 550000=x(1+\frac{2}{100} (5))\)

Solve for the brackets.

\(\displaystyle 550000=\frac{11}{10}x\)

Multiply both sides of the equation by \(\frac{10}{11}\).
