Jonah has chosen the greater number.
Given, Sue and Jonah chose numbers for a place value game.
As a way to express numbers, a number system is a way of expressing them. It is a method of describing numbers from a particular set mathematically by consistently employing digits or other symbols. Every number is given a distinct representation, and the figures' algebraic and mathematical structures are also shown.
Sue chose the number = one hundred fifty two thousand
= 152000
= 1.52 lakhs
Jonah chose the number = five million
= 5,000,000
we know that 10 lakhs = 1 million = 1,000,000
therefore, 5 million = 5 × 10 lakhs
= 50 lakhs
50 lakhs > 1.5 lakhs
the greater number is 5 million.
Therefore , the greater number chose by Sue and Jonah is of Jonah's that is 5 million.

What is the equation of the line that passes through the point (-2,-1)(−2,−1) and has a slope of 5/2
The equation of line having slope of 5/2 is given as 2y -5x = 8.
What is termed as the equation of line in point-slope form?A line's equation written in point slope form is (y - y₁) = m(x – x₁).When the line passing through the origin the equation of a line with slope m is: y - 0 = m(x = 0), i.e. y = mx.where m is the slope and (x₁, y₁) are the coordinates passing point on the line .As, per the given question;
The slope of the line is given as; m = 5/2
The coordinates of the passing points (-2, -1).
Thus, (x₁, y₂) = (-2, -1).
The equation of the becomes.
(y - y₁) = m (x – x₁)
Put the values;
y - (-1) = (5/2)(x - (-2))
Simplifying
y + 1 = (5/2)(x + 2)
2y + 2 = 5x + 10
2y -5x = 8
The equation of line is calculated as 2y - 5x = 8.

Solve the following system of equations using either Gaussian elimination or a matrix. Write your answer as a point and explain how you would check your work:
2xy + 4z = 33
x + 2y - 3z = -26
-5x - 3y + 5z = 23
Using Gaussian elimination, the solution to the given system of equations is given as follows:
x = 5, y = -11, z = 3.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the equations are given as follows:
2x - y + 4z = 33.x + 2y - 3z = -26.-5x - 3y + 5z = 23.(I suppose there was a typing mistake on the first equation, as Gaussian elimination can only be applied to solve linear systems).
For Gaussian elimination, the first step is building the matrix of the system, in which:
The first three columns contain the coefficients of x, y and z, respectively.The last column contains the results of the operations.Hence, the matrix of the system is given as follows:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\1&2&-3&-26\\-5&-3&5&23\end{array}\right][/tex]
Then, we need to make the coefficient of x zero in the second and third rows, hence:
R2 -> 2R2 - R1.R3 -> 5R1 + 2R3.Then the matrix will be given by:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&-11&30&211\end{array}\right][/tex]
Now we need to make the coefficient of y on the third row zero, hence:
R3 -> 11R2 + 5R3.
Then:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&0&40&120\end{array}\right][/tex]
From the third row, we have that:
40z = 120
z = 120/40
z = 3.
From the second row, we have that:
5y - 10z = -85
5y - 30 = -85
5y = -55
y = -11.
From the first row, we have that:
2x - y + 4z = 33
2x + 11 + 12 = 33
2x = 10
x = 5.
Hence the solution of the system is given by:
x = 5, y = -11, z = 3.

Eileen is 3y years old now. Her mother is 4 times as old as her. Find their total age in 7 years' time. Give your answer in terms of y.
Answer:
15y+14
Step-by-step explanation
Answer: 14 + 15y
Step-by-step explanation:
E = Eileen’s age = 3y
M = Mum’s age
Total Age = 14 + 3y + 4(3y)
= 14 + 15y
Total age in 7 years time is their current ages plus 7 years for each (14 years)
Eileen is 3y, and her mum is 4 times that, which is 12y, meaning that their total ages are 3y + 12y, or, 15y.
Total age is then 15y + 14. Since we don’t know what y equals, we cannot add these two terms, and we can just leave them like that!
So, the answer is 14 + 15y.

A small cylindrical can of tuna has a radius of 4 centimeters and a height of 3.8 centimeters. A larger and similar can of tuna has a radius of 5.2 centimeters.
a. What is the scale factor of the cylinders?
The scale factor of the two similar cylindrical cans of tuna is 13/10.
Solids of the same type that have proportional corresponding linear measures are similar solids. In the case of similar cylinder:
height of A / height of B = radius of A / radius of B
Scale factor refers to the ratio of the corresponding dimensions of similar solids.
If the smaller cylindrical can of tuna has a radius of 4 centimeters and the larger and similar can of tuna has a radius of 5.2 centimeters, then the scale factor is:
scale factor = radius of larger can/ radius of smaller can
scale factor = 5.2 cm / 4 cm

Lee is laying out a design for the tiles of a section of his bathroom floor. he will use 1 white tile for every 6 black tiles to have a total of 28 tiles in the design. how many of each type of tile will lee use?
If Lee is laying out a design for the tiles of a section of his bathroom floor and he will use 1 white tile for every 6 black tiles to have a total of 28 tiles in the design then the number of white and black tiles Lee will use is equal to 4 and 24 respectively.
The number of white and black tiles Lee will use can be determined by using an algebraic expression.
As 1 white tile is used for every 6 black tiles, an algebraic expression can be represented as,
x + 6x = 28
By solving the value of x, the number of each type of tile that Lee will use can be calculated,
x + 6x = 28
7x = 28
x = 28 ÷ 7
x = 4
As there is one white tile for every six black tiles,
White tiles = 1(x) = 1(4) = 4
Black tiles = 6(x) = 6(4) = 24
Hence the number of white tiles Lee will use is equal to 4 and the number of black tiles Lee will use is equal to 24.

For any correlation, people often assume that change in one quantity causes change in the second quantity. This is not always true. For each situation, do you think that change in the first quantity causes change in the second quantity? What else may have affected the change in the second quantity?
a person's age and the number of cassette tapes he or she owns
For the given situation, we can clearly say that the change in one quantity will cause a change in the second quantity as well.
Correlation is a relationship between the values of two variables. A scatter plot is a useful tool for displaying data about two variables as a series of points in the x and y plane and determining whether there is a correlation between the variables.
Causality means that one event causes another. Causality can only be determined by well-designed experiments. In such experiments, similar groups receive different treatments, and the results of each group are examined.
From the above information, we concluded that a person's age and the number of cassette tapes he/she owns are correlated more he lives the more he buys the cassette tapes. So we can make relation from this,
Person's Age ∝ Number of Cassette
This clearly states that by increasing/changing one quantity we will increase/change the other quantity as well.
Similarly, now that they have a direct relation if we decrease the Age of the person, the number of Cassette's will also decrease. A positive correlation we can call it.

A circle is a curve sketched out by a point moving in a plane. The diameter and circumference of the circle are (x/4) units and (x/4)π units, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that radius of the circle is x/8 units. Therefore, the diameter and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
= 2 × (x/8) units
= x/4 units
Circumference of circle = 2 × π × (Radius of the circle)

Use the formula for the probability of two dependent events P(A and B) to derive the conditional probability formula for P(B | A) .
The conditional probability formula for P(B | A) has been derived from two dependent events P(A and B).
What is said to be dependent events?When the outcome from one event influences the outcome of the other, two events are referred to as dependent.
Dependent events in probability are generally real-life events that depend on another event to occur. Sam, for example, did well on his math test because he prepared; the gym class used to have a football session even though Adam brought a football from home. When you look at these examples, you will realize that one occurrence is dependent on the other.Derivation of conditional probability from two dependent events P(A and B) is-
The probability multiplication rule is used to derive the conditional probability formula, P(A and B) = P(A)×P(B|A).
This rule is also known as P(AB). The Union symbol (∪) represents "and," as in event A occurring and event B occurring.
Step 1: Write the multiplication rule down:
P(A and B) = P(A)*P(B|A)
Step 2: P(A) divides both sides of the equation:
P(A and B) / P(A) = P(A)*P(B|A) / / P(A)
Step 3: On the right side of the equation, cancel P(A):
P(A and B) / P(A) = P(B|A)
Step 4: Rewrite the equation as follows:
P(B|A) = P(A and B) / P(A)
Therefore, P(B | A) conditional probability formula is compiled from two dependent events P (A and B).

Describe the transformation of the parent function f(x) . h(x)=0.25 f(x)
The transformation applied to the parent function is vertical compression by a factor of 0.25.
In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value.
Vertical compression helps shrink features vertically. Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.
