b). A pupil solved a fraction task as follows: 3/5 + 1/2 = 4/7. Identify what the child did wrongly. Explain how you would solve the task correctly, leaving your answer as a common fraction.
The correct answer to the fraction task is 3/5 + 1/2 = 11/10 expressed as a fraction and 4/7 is incorrect answer
The pupil made an error in their addition of 3/5 and 1/2, resulting in an incorrect answer of 4/7.
To solve the task correctly, we need to find a common denominator for 3/5 and 1/2.
The least common multiple of 5 and 2 is 10, so we can rewrite the fractions with a denominator of 10 as follows:
3/5 = 6/10
1/2 = 5/10
Now we can add the fractions:
6/10 + 5/10 = 11/10
Hence, the correct answer to the fraction task is 3/5 + 1/2 = 11/10 expressed as a fraction.

The solution to the system of equations is given as follows:
x = 3z + 3.y = -2z + 4.z = z.How to solve the system of equations?Considering the augmented matrix, the system of equations is defined as follows:
x + y - z = 7.2x + 3y = 18.-5x - 7y + z = -43.Adding the first and third equations, we have that:
-4x - 6y = -36.
From the second equation, we have that:
2x + 3y = 18.
The addition equation is a multiple of this equation, hence the system has an infinite number of solutions.
From the second equation, we have that:
2x + 3y = 18.
x + 1.5y = 9
x = 9 - 1.5y.
The definition for z is given as follows:
z = x + y - 7.
Hence the variable y is:
y = z - x + 7.
The variable x is of:
x = 9 - 1.5(z - x + 7)
x = 9 - 1.5z + 1.5x - 10.5
0.5x = 1.5 + 1.5z
x = 3z + 3.
The variable y is:
y = z - 3z - 3 + 7
y = -2z + 4.
Hence the solution is:
x = 3z + 3.y = -2z + 4.z = z.More can be learned about a system of equations at https://brainly.com/question/13729904

The probability of just thunder is 0.196.
We have,
The probability of rain P(A) = 1/2
The probability of thunder and raining P(A ∩ B) = 1/3
The probability of rain and thunder P(A U B) = 11/30
Now,
Using the addition rule of probability.
P(A U B) = P(A) + P(B) - P(A∩B)
Substituting.
11/30 = 1/2 + P(B) - 1/3

The distance, along the ground, from the bottom of the ladder to the building is 8 feet. The distance from the bottom of the building to the point where the ladder is touching the building is unknown.
Determine the distance from the bottom of the building to the point where the ladder is touching the building for triangle 2.
27 feet
18 feet
12 feet
5 feet
The distance from the bottom of the building to the point where the ladder is touching the building for triangle 2, obtained using trigonometric ratio of tangent is 12 feet. The correct option is therefore;
12 feet
What are the trigonometric ratios?The trigonometric ratios are the value relationship between an interior angle of a right triangle and two of the sides of the triangle.
The right triangles are similar, therefore, the tangent of the angle the ladder makes with the ground are the same, which indicates;
tan(θ) = (Length of the side facing the angle θ) ÷ (Length of the side adjacent to the angle θ)
The side facing the angle is the distance from the bottom to the point where the ladder touches the building.
The adjacent to the angle is the horizontal distance from the bottom to the ladder to the building.
Therefore; tan(θ) = 18/12 = x/8
Where x = The distance from the bottom of the building to the point the ladder touches the building for triangle 2
18/12 = x/8
x = 18/12 × 8 = 12

The table below shows some of the data that were used to find this model. Year 1995 1998 2001 2004 2006 Number of People Who Moved to Another State (millions) a. When t O what is the value of n ? What does it mean in this situation? Select an answer 1.7 1.1 1.0 1.5 2.1 b. Estimate the number of people who moved to another state in 2005. million (Round to the nearest tenth of a million.) c. Predict the number of people who moved to another state in 2014. million (Round to the nearest tenth of a million.)
When t = 0, the value of n is approximately 3.93 million. The estimated number of people who moved to another state in 2005 is approximately 1.68 million. The predicted number of people who moved to another state in 2014 is approximately 6.81 million.
we need to substitute the given values of t (years since 1990) into the equation n = 0.03t² - 0.6t + 3.93. Let's calculate the values accordingly:
a. When t = 0 (which corresponds to the year 1990), we substitute this value into the equation:
n = 0.03(0)² - 0.6(0) + 3.93
n = 0 + 0 + 3.93
n ≈ 3.93
So, when t = 0, the value of n is approximately 3.93 million. In this context, it means that in the year 1990, around 3.93 million people moved to another state.
b. To estimate the number of people who moved to another state in 2005 (t = 2005 - 1990 = 15), we substitute this value into the equation:
n = 0.03(15)² - 0.6(15) + 3.93
n = 0.03(225) - 9 + 3.93
n = 6.75 - 9 + 3.93
n ≈ 1.68
Therefore, the estimated number of people who moved to another state in 2005 is approximately 1.68 million.
c. To predict the number of people who moved to another state in 2014 (t = 2014 - 1990 = 24), we substitute this value into the equation:
n = 0.03(24)² - 0.6(24) + 3.93
n = 0.03(576) - 14.4 + 3.93
n = 17.28 - 14.4 + 3.93
n ≈ 6.81
Hence, the predicted number of people who moved to another state in 2014 is approximately 6.81 million.

What is the slope of the line?
Write your answer as an integer or simplified fraction.
The slope of the line passing through the given points is -2.5.
To find the slope of a line passing through two points, we need to use the formula:
Slope = (Change in y) / (Change in x
We can choose any two points from the given table to find the slope of the line. Let's choose the points (4, 19) and (6, 14).
Change in y = 14 - 19 = -5
Change in x = 6 - 4 = 2
Slope = (-5) / 2 = -2.5
Therefore, the slope of the line passing through the given points is -2.5.
The slope of a line represents the steepness of the line. If the slope is positive, the line is increasing as we move from left to right. If the slope is negative, the line is decreasing as we move from left to right. A slope of 0 represents a horizontal line, while an undefined slope represents a vertical line.
In this case, the slope of -2.5 indicates that the line is decreasing at a moderate rate as we move from left to right. The higher the absolute value of the slope, the steeper the line.
It is important to note that the slope is constant for any two points on a straight line. Therefore, we can choose any other two points from the table to find the slope, and we will get the same result.

The pair of solids is similar. Find the volume of each solid. Round to the nearest tenth, if necessary.
The volume of small solid is 24 cm³ and volume of big solid is 216 cm³.
Given that
Height of small solid = 4 cm = h₁
Width of small solid = 2 cm = w₁
Length of small solid = 3 cm = L₁
Width of big solid = 6 cm = w₂
Let,
Height of small solid = h₂
Length of small solid = L₂
Since we know that volume of solid = length x width x height
Therefore, volume of small solid = 4x2x3 = 24 cm³
Since both the solids are similar,
So,
⇒ w₁/w₂ = h₁/h₂
⇒ 2/6 = 4/h₂
⇒ h₂ = 12 cm
Also,
w₁/w₂ = L₁/L₂
⇒2/6 = 3/L₂
⇒ L₂= 9 cm
