The difference between 1/5 and 2/10 is that they are different representations of the same value.

The ratio is a comparison of two quantities while proportional reasoning involves finding an equivalent ratio.

"Fifth" can refer to the ordinal number of a position or the unit fraction 1/5.

The diagram can be used to illustrate fraction concepts.

1/5 is simple, but 2/10 can be reduced to 1/5 by dividing both numbers by 2. They are both 0.2 or 20%. 1/5 and 2/10 are different fractions with different purposes.

Use 1/5 for 5 parts and 1/5 (simplified from 2/10) for 10 parts. 1/5 and 2/10 = 0.2, ratio reasoning emphasizes ratios between quantities. A 2:3 boys-to-girls ratio compares the constant ratio between changing quantities.

Proportional reasoning maintains constant ratios between quantities, while ratio reasoning uses fractions or ratios to compare relationships. For instance, if distance doubles, so does speed.

Step 3/5: "Fifth" is the ordinal number for the object five places away in a sequence. See diagram. The fifth circle is 1/5 of a whole in unit fraction sequence. Imagine a rectangle divided into five equal parts, each shaded to show 1/5. Shaded part = 1/5 of whole.

To show 25/7 with area model, make 7x25 rectangle and split into 7 equal parts. 25/7 per part.

1.2 The set model:

To represent 25/7, divide 25 objects into 7 equal sets, resulting in 3 objects per set with 1 left over. This represents the fraction of 25/7.

1.3 The length model:

To show 25/7 on a length model, draw a line of 25 units and divide it into seven equal parts. Each part represents 1/7 or 25/7.

Step 5/5

Let's assume the width of the rectangular piece of paper as x cm. Then the length of the paper would be:

Now we know that the perimeter of the rectangle is given by the formula:

So, for this rectangle:

54 = 2(5x + x)

Simplifying and solving for x, we get:

54 = 2(6x)

27 = 6x

x = 4.5 cm

Therefore, the width of the paper is 4.5 cm and the length is 5 times the width which is 22.5 cm.

The difference between 1/5 and 2/10 is that they are different representations of the same value.

The sum of money is approximately Rs. 6250.

Given that the difference is Rs. 40, we must calculate the difference between compound interest and simple interest over a period of two years at an annual rate of 8%.

Assume that P represents the principal amount of money.

The formula for simple interest is: SI = (P * R * T) / 100

The formula for compound interest is: [tex]CI = P * (1 + R/100)^T^ - ^P[/tex]

Where

The difference between compound interest and simple interest is Rs. 40. Therefore:

CI - SI = Rs. 40

Substituting the formulas and values into the equation:

[tex](P * (1 + 8/100)^2 - P) - (P * 8 * 2 / 100) = 40[/tex]

Simplifying further:

[tex](P * (1.08^2) - P) - (0.16P) = 40[/tex]

[tex](P * 1.1664 - P) - 0.16P = 40[/tex]

The words that has to be kept in the blank space to prove the similarity are (a, 0), (0, a) and scale factor.

Here we have to choose the words to finish the explanation of how to plan a coordinate proof to show that all isosceles right triangles are similar.

Isosceles right triangles are the right triangles which has the two legs of same length.

For that first consider an isosceles right triangle with legs having length "a".

Then if we place the triangle with one of the vertices at origin, then since the length of the legs is "a", the other vertices will be at (a, 0) and (0, a).

If we place another triangle similarly with length of legs "b", then we have to prove that they are similar.

For them to be similar, there must exist a scale factor that maps one triangle on to the other.

Hence the spaces are (a, 0), (0, a) and scale factor.

The Probability of Boris' character casting a spell is 8/15, based on the given odds in favor of 8/7.

The probability of Boris' character casting a spell, we can use the odds in favor of casting a spell. The odds in favor are given as 8/7.

Odds in favor of an event are calculated as the ratio of the number of favorable outcomes to the number of unfavorable outcomes. In this case, the favorable outcomes are the instances where Boris' character casts a spell, and the unfavorable outcomes are the instances where his character does not cast a spell.

Let's represent the probability of casting a spell as P(casting spell). We can use the formula for odds in favor to find the probability:

Odds in favor = Favorable outcomes / Unfavorable outcomes

8/7 = Favorable outcomes / Unfavorable outcomes

To solve for the probability, we need to convert the odds into a fraction. We can do this by considering the odds as a ratio of favorable outcomes to the total number of outcomes.

The odds can be written as:

8/(8+7) = Favorable outcomes / (Favorable outcomes + Unfavorable outcomes)

8/(8+7) = Favorable outcomes / Total outcomes

8/15 = Favorable outcomes / Total outcomes

Since the total outcomes represent all possible outcomes, the denominator represents the total number of outcomes, which includes both the favorable and unfavorable outcomes.

Therefore, the probability of Boris' character casting a spell is 8/15.

In summary, the probability of Boris' character casting a spell is 8/15, based on the given odds in favor of 8/7.

The solutions to the circle equations in the attached figure are: (5) (x + 2)² + (y - 1)² = 20, (6) x² + y² = 9, (7) (x + 3)² + (y - 1)² = -9 and (8) (x - 4)² + (y - 3)² = -16

Equation of a Circle in the Cartesian coordinate system (x, y) is given by:

(x - h)² + (y - k)² = r²

where

(h, k) = coordinates of the center of the circle

r = radius.

The expression (x - h)² + (y - k)² represents the squared distance between any point (x, y) on the circle and the center point (h, k). By setting this expression equal to the square of the radius, r², we ensure that all points on the circle are equidistant from the center.

You can also expand the equation to get the standard form:

x² - 2hx + h² + y² - 2ky + k² = r².

Using the information above, let us solve the circle equations:

5) y² + 4x - 20 - 2y = -x²

First we need to find the coordinates (h, k) of the circle

x² + 4x + y² - 2y = 20

-2h = 4 => h = -2

-2k = -2 => k = 1

(h,k) = (-2, 1)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (-2))² + (y - (1))² = 20

(x + 2)² + (y - 1)² = 20

Therefore the solution to the circle equation is: (x + 2)² + (y - 1)² = 20 and the curve is attached.

6) -9 = -y² - x²

First we need to find the coordinates (h, k) of the circle

x² + y² = 9

-2h = 0 => h = 0

-2k = 0 => k = 0

(h, k) = (0, 0)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (0))² + (y - (0))² = 9

x² + y² = 9

Therefore the solution to the circle equation is: x² + y² = 9 and the curve is attached.

7) 9 = 2y - y² - 6x - x²

First we need to find the coordinates (h, k) of the circle

x² + 6x + y² - 2y = -9

-2h = 6 => h = -3

-2k = -2 => k = 1

(h, k) = (-3, 1)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (-3))² + (y - (1))² = -9

(x + 3)² + (y - 1)² = -9

Therefore the solution to the circle equation is: (x + 3)² + (y - 1)² = -9 and the curve is attached

8) 16 + x² + y² - 8x - 6y = 0

First we need to find the coordinates (h, k) of the circle

x² - 8x + y² - 6y = -16

-2h = -8 => h = 4

-2k = -6 => k = 3

(h,k) = (4, 3)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (4))² + (y - (3))² = -16

(x - 4)² + (y - 3)² = -16

Therefore the solution to the circle equation is: (x - 4)² + (y - 3)² = -16 and the curve is attached.

The experimental probability that the next train to pull into Lakeside Station will be full is 7/10.

The experimental probability of the next train to pull into Lakeside Station being full can be calculated by dividing the number of times a full train occurred by the total number of trains observed.

Given that out of the last 20 trains, 14 were full, we can express the experimental probability as a fraction:

P(full) = Number of full trains / Total number of trains observed

P(full) = 14 / 20

Two of the side lengths are given, to find the third side length, we use the following equation based on similarity ratio:

[tex] \frac{kj}{nm} = \frac{kl}{no} [/tex]

[tex] \frac{8}{18.4} = \frac{9}{no} [/tex]

8NO = 165.6

NO = 20.7

20.7 + 23 + 18.4 = 62.1 square units.

Answer:

Number of TAILS outcomes = 100 - 58 = 42

Experimental probability of TAILS = Number of TAILS outcomes / Total number of outcomes = 42/100 = 0.42

The theoretical probability of getting HEADS or TAILS is 0.5 each, assuming the penny is fair.

The experimental probability of HEADS is 58/100 = 0.58, which is close to the theoretical probability of 0.5. This suggests that Aaron's experiment is consistent with the theoretical probability. Similarly, the experimental probability of TAILS is 0.42, which is also close to the theoretical probability of 0.5. This further supports the idea that the penny is fair.

The correct solution is,

D. Mean = 50.4,

Variance = 27.2,

Standard deviation = 5.2.

Now, Formula for the mean, variance, and standard deviation of the given values,

Mean (μ) = (Σx) / n

Variance (σ) = (Σ(x-μ)) / n

Standard deviation (σ) = sqrt(σ)

where: Σx = sum of the values

Σ(x-μ)² = sum of the squared differences between each value and the mean

n = number of values

Substituting the given values into these formulas, we get:

Mean (μ) = (50 + 46 + 53 + 51 + 52) / 5

Mean (μ) ≈ 50.4

Variance (σ) = [(14 - 50.4)² + (50 - 50.4)² + (-0.4 - 50.4)² + ... + (2.6 - 50.4)] / 13

Variance (σ) ≈ 27.2

Standard deviation (σ) = √(27.2)

Standard deviation (σ) ≈ 5.2

Answer: the present age of son is 15 years, and the present age of father is 45 years.

Step-by-step explanation:

Let the age of son be 'x' and that of his father be 'y'.

So according to the question, the 1st equation that can be formed will be:

y = 3(x) ->(1)

[as father's age is 3 times the age of son]

Now after 5 years:

Age of son = (x+5)

Age of father = (y+5)

So according to the question, the 2nd equation that can be formed will be:

(y+5) = 2.5×(x+5) ->(2)

[as father is now two and half times old as his son]

Substituting the value of equation (1) in (2), we get:

(3x+5) = 2.5×(x+5)

=> 3x + 5 = 2.5x + 12.5

=> 3x - 2.5x = 12.5 - 5

=> 0.5x = 7.5

=> x = 7.5/0.5 = 15

Thus, the present age of son is 15 years.

Note : we can calculate the age of father by putting the value of x in equation (1) or (2):

y = 3(x) = 3 × 15 = 45 (putting x in equation 1)

Thus, the present age of father is 45 years.
