A square fits exactly inside a circle with all of its vertices being on the circumference of the circle.
The square has sides of lengths x cm
The area of the circle is 56cm^2
Give your answer to 3sf.
The side of the square is 5.9 cm
Step-by-step explanation:
Area of the circle = 56 square cm
Side of the square= x
Area = π(r x r)
56 = π (r x r)
√17.83 = r
r = 4.22 cm
Diameter = 8.44cm
The diameter is equal to the diagonal of the square.
8.44 = x√2
x = 8.44/√2
= 5.9 cm
The side of the square is 5.9 cm

A tree is 11 meters tall. What is its height in feet?use the following conversion 1 meter is 3.3 feet
Answer:
The tree is 36.3ft
Explanation:
Tree=11m
If 1 meter is equal to 3.3 feet we multiple the number of meters(11) to 3.3
To convert from meters to feet, we multiply the given length in meters by the conversion ratio of 3.3. The tree, being 11 meters tall, is therefore approximately 36.3 feet tall.
Explanation:The question asks us to convert the height of a tree from meters to feet. The tree is 11 meters tall and we'll use the conversion rate of 1 meter being equal to 3.3 feet. To do this, we multiply the height of the tree in meters by the conversion ratio: 11 meters * 3.3 feet/meter. This gives us a height of 36.3 feet. So the tree is 36.3 feet tall.

A fashion store is having a sale advertising 'one
third' off all prices. If a pair of trousers costs £47.46
in the sale, what did it cost before?
To find the original price before the 'one third' discount, divide the sale price by 2 and then multiply by 3. The original price of the trousers would be £71.19.
Explanation:The fashion store sale offers a 'one-third' discount off regular prices. To find the original price of a pair of trousers that cost £47.46 after the discount, we should understand that this sale price represents two-thirds of the original price, as the discount removed one-third of the original price. Hence, to find the original price, we need to divide the sale price by 2 and then multiply the result by 3 (since the original price is equivalently 3 parts if two parts is the sale price). So, the original price is (£47.46 ÷ 2)*3 = £71.19.

Scores on a test have a mean of 66 and a standard deviation of 9. Michelle has a score of 57. Convert Michelle’s score to z-score
Answer:
-1
Step-by-step explanation:
We have that the mean (m) is equal to 66, the standard deviation (sd) 9
They ask us for P (x <57)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (57 - 66) / (9)
z = -1
57 score to z-score is -1
Write a cosine function that has a midline of 5, an amplitude of 3 and a frequency of 4/5
The cosine function with a midline of 5, an amplitude of 3 and a frequency of 4/5 is: f(x) = 3 * cos((8π/5) * x) + 5.
Given:
Amplitude (A) = 3
Frequency (f) = 4/5
Midline = 5
A cosine function with a midline of 5, an amplitude of 3, and a frequency of 4/5 can be expressed as:
f(x) = A cos(2π f x) + midline
Substituting these values into the equation, we get:
f(x) = 3 * cos(2π * (4/5) * x) + 5
Therefore, the cosine function is f(x) = 3 * cos((8π/5) * x) + 5.

2. symmetric
3. positively skewed
4. exponentially skewed
Answer:
1. Negatively skewed
General Formulas and Concepts:
Statistics
Analyzing data graphsCorrelations and skew-ageStep-by-step explanation:
If we define left of the graph as "negative" and right of the graph "positive", we can see how most data points are shifted to the left.
∴ It would be negatively skewed.
It would not be 2. Symmetric because if we draw a line of symmetry, it is in fact unsymmetrical.
It would not be 3. Positively skewed because the data would be grouped towards the right.
It would not be 4. Exponentially skewed because the data is not strictly increasing bigger and bigger.
Here is the histogram of a data distribution. All class widths are 1.
1 2 3 4 5 6 7 8 9 10
What is the median of the distribution
The required median of the distribution is 7. Option B is correct.
What is the median?When a dataset is ordered, the median is the value that is exactly in the middle. It is a measure of central tendency that distinguishes between the lowest and top 50% of data.
Here,
To find the median of a distribution, we need to arrange the data in order from lowest to highest, and then identify the middle value. If there are an odd number of data points, the median is the middle value. If there are an even number of data points, the median is the average of the two middle values.
So, let's first list the values in ascending order:
1, 2, 3, 3, 4, 5, 5, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9
The total number of data points is 20, which is even. Therefore, we need to find the average of the two middle values, which are the 10th and 11th values.
The 10th value is 7 and the 11th value is 7 as well, so the median is the average of these two values:
Median = (7+7)/2 = 7
Therefore, the median of the distribution is 7.

O
c. 2x - 4
O
D. 4X – 15
Answer:
To find the width of the rectangle, we can use the formula for the area of a rectangle, which is the product of its length and width. In your question, you provided the area (A) as A = 8x^2 - 10x - 12, and the length is given as 4x + 3.
Let's denote the width as "w." So, we have:
Area (A) = Length (L) × Width (w)
A = (4x + 3)w
Now, we can solve for the width (w):
w = A / (4x + 3)
w = (8x^2 - 10x - 12) / (4x + 3)
Now, we need to simplify the expression for w. We can factor the numerator to see if there are any common factors:
w = [(2x - 4)(4x + 3)] / (4x + 3)
Now, we can cancel out the common factor of (4x + 3) in the numerator and denominator:
w = 2x - 4
So, the width of the rectangle is 2x - 4, which corresponds to option (C).
Step-by-step explanation:
The width of the rectangle is (8x^2 - 10x - 12) / (4x + 3)
Explanation:To find the width of the rectangle, we need to equate the expression for the area of the rectangle to a product of its length and width. In this case, we have the area A = 8x2 - 10x - 12 and the length is given by 4x + 3. So, we can set up the equation (4x + 3) * width = A. Let's solve for the width:
So, the width of the rectangle is given by the expression (8x2 - 10x - 12) / (4x + 3).

What is the surface area of the triangular prism made by folding up this net? Given:
a= 20 cm b= 25 cm C= 28 cm
The surface area of a triangular prism can be found by adding the areas of all faces. The triangular faces are calculated using the formula for the area of a triangle, and the rectangular faces are calculated using the given dimensions of the sides of the triangles. The total surface area is the sum of these areas.
Explanation:The question is asking for the surface area of a triangular prism. In order to find this, you need to add the areas of all the faces. A triangular prism has 5 faces, 2 are triangles, and 3 are rectangles.
For the triangular faces, we use the formula for the area of a triangle which is 1/2ab, where a and b are the provided dimensions. Thus, the triangle's area is 1/2 * 20 cm * 25 cm = 250 cm². Since there are two of these, the total area is 500 cm².
The rectangular faces are more challenging since it seems like we don't have enough information. The rectangle is made up of the sides of the triangles, so one side is 20 cm. However, we don't know the length (C) of the triangle which would be the other side of the rectangle. Assuming C is given, multiply each corresponding side to get the area of each rectangle, and add all together.
The final step is to add the area of the triangles and rectangles together to find the total surface area of the prism.

Solve: 2/v+1/5=3/w for w
Final answer:
To solve for w in the equation 2/v + 1/5 = 3/w, a series of algebraic steps including taking reciprocals and simplifying complex fractions leads to w = (15v)/(10 + 2v).
Explanation:
To solve the equation 2/v + 1/5 = 3/w for w, we must isolate w. This involves several algebraic steps. First, we can take the reciprocal of both sides of the equation in order to get w on one side:
∑1/(2/v + 1/5) = 1/(3/w)
Through the properties of reciprocals and complex fractions, the equation simplifies down to:
w = ∑3 × (v × 5)/(2×5 + v)
This can be further simplified by multiplying through by 3 and combining terms under a single denominator. After simplification, we obtain the relationship:
w = (15v)/(10 + 2v)

The measure of angle Y is 76 degrees.
Step-by-step explanation:
A kite is a quadrilateral, so its angles must add up to 360 degrees. We can represent this with an equation:
W+X+Y+Z = 360
W+132+Y+76 = 360
We know that W=Y because side WX = side WY.
Y+ 208+Y = 360
2Y = 152
Y = 76 degrees
