Liam works at a zoo. He was looking at some data showing the masses of their 5 African elephants. The mean mass of the elephants was 3,800 kilograms and the median mass was 3,600 kilograms. The heaviest elephant, named Omar, was recorded as 6,000 kilograms. Liam then found out that Omar's mass was written down incorrectly, and that Omar actually has a mass of 7,000 kilograms. How will increasing Omar's mass affect the mean and median?
The increase of Omar's mass from 6000kg to 7000kg will raise the mean mass of the elephants because the mean involves all values. However, it won't affect the median mass because the position of the middle value in the set won't change.
Explanation:The correction of Omar's mass from 6,000 kilograms to 7,000 kilograms will affect both the mean and the median mass of the elephants. However, the effect on each measure of central tendency will be different.
The mean is the average, calculated by adding up all values and then dividing by the number of values. If Omar's weight is increased, the total mass of the elephants will increase, leading to an increase in the mean mass of the elephants.
However, the median, which is the middle value when all values are arranged in ascending order, will not change because it only depends on the arrangement of values, not their actual size. Since Omar's mass is already the largest value, an increase in his mass will not change the position of the middle value.

Which ordered pair (a, b) is a solution to the given system of linear equations?
A (1, 7)
B (3, 1)
C (11, –23)
D (23, –11)
Answer:
C. (11,-23)
Step-by-step explanation:
The given equations are
[tex]3a+b=10[/tex].....................equation 1
[tex]-4a-2b=2[/tex]...................equation 2
Multiply first equation by 2
[tex]6a+2b=20[/tex]
Now add this new equation to 2nd equation
[tex]6a-4a +2b-2b = 20+2[/tex]
[tex]2a = 22[/tex]
Divide both sides by 2
[tex]a=11[/tex]
We got a=11 , plug this value in anyone equation
3(11)+b=10[tex][/tex]
[tex]33+b=10[/tex]
Subtract 33 from both sides
[tex]b=-23[/tex]
So solution is (a,b) = ( 11,-23)
Two large numbers of the Fibonacci sequence are f(50)=12,586,269,025 and f(51)= 20,365,011,074 if these two numbers are added what number results
Answer:
f(52) = 32,951,280,099
Step-by-step explanation:
In Fibonacci sequence, the sum of the two preceding sequence of the sequence is always equivalent to the next sequence.
For example, this is a Fibonacci sequence 1,2,3,5,8... As you can see that the sum of the two preceding sequence gave the next sequence i.e 1+2 = 3, 2+3 = 5, 3+5 = 8 etc and the chain continues like that.
If we are now given two large numbers of. Fibonacci sequence to bef(50)=12,586,269,025 and f(51)= 20,365,011,074
The next sequence f(52) will be the sum of the preceding sequences f(50) and f(51) that is;
f(52) = f(50) + f(51)
f(52) = 12,586,269,025 + 20,365,011,074
f(52) = 32,951,280,099
The resulting numbers if they are added is 32,951,280,099.

At LaMar’s birthday party, his parents served slices of plain, sausage, or pepperoni pizza. They also served cups of milk, orange juice, apple juice, or lemonade. If each guest at the party chose one slice of pizza and one type of drink, how many different combinations were possible?
Answer: 12 different combinations were possible.
Step-by-step explanation:
Given: At LaMar’s birthday party, his parents served slices of plain, sausage, or pepperoni pizza.
i.e. The number of types of pizza = 3
They also served cups of milk, orange juice, apple juice, or lemonade.
i.e. The number of types of drinks = 4
Now, if each guest at the party chose one slice of pizza and one type of drink, then the number of different possible combinations are :
[tex]3\times4=12[/tex]
Hence, there were 12 different combinations .

A cone with a radius of 12 cm and a height of 12 cm has the same volume as a cylinder with a radius of 8 cm. What is the height of the cylinder?
A) 3 cm
B) 6 cm
C) 9 cm
D) 12 cm
Answer:
The correct option is C. The height of the cylinder is 9 cm.
Step-by-step explanation:
The radius of cone is 12 cm and the height of cone is 12 cm.
The volume of cone is
[tex]V=\frac{1}{3}\pi r^2h[/tex]
[tex]V_1=\frac{1}{3}\pi (12)^2(12)[/tex]
[tex]V_1=576\pi[/tex]
The radius of cylinder is 8 cm. The volume of cylinder is
[tex]V=\pi r^2h[/tex]
[tex]V_2=\pi (8)^2h[/tex]
[tex]V_2=64\pi h[/tex]
It is given that the volume of cone and cylinder is same.
[tex]V_1=V_2[/tex]
[tex]576\pi=64\pi h[/tex]
[tex]\frac{576\pi}{64\pi}=h[/tex]
[tex]9=h[/tex]
Therefore the height of the cylinder is 9 cm and option C is correct.
To find the height of the cylinder that has the same volume as a cone, we can compare their volumes. By setting the volumes equal to each other and simplifying the equation, we find that the height of the cylinder is 9 cm.
Explanation:To find the height of the cylinder, we need to compare the volumes of the cone and the cylinder. The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height. The volume of the cone with radius 12 cm and height 12 cm is (1/3)π(12^2)(12) = 576π cm³. Now, let's calculate the volume of the cylinder using the formula V = πr^2h, with radius 8 cm. We know that the volumes of the cone and the cylinder are equal, so 576π = π(8^2)h. Simplifying this equation, we get 576π = 64πh. Dividing both sides of the equation by 64π, we find h = 9 cm. Therefore, the height of the cylinder is 9 cm.

Use synthetic division to find the quotient and the remainder for the problem: (12x^4 + 5^3 + 3x^2 - 5)/(x+1)?,
To use synthetic division to divide a polynomial by a linear expression, follow the steps: arrange the terms, change the sign of the linear expression, bring down the coefficient, multiply and add, write the result, and determine the quotient and remainder.
Explanation:To use synthetic division to divide a polynomial by a linear expression, follow these steps:
Arrange the terms of the polynomial in descending order of their degrees.Change the sign of the linear expression you're dividing by.Write down the coefficient of the term with the highest degree of the polynomial and bring it down.Multiply this coefficient by the changed sign of the linear expression and write the result under the next coefficient.Add these two values together and write the result under the next coefficient. Repeat this process until you've reached the constant term.Write the final result as the quotient and the last value as the remainder.In this case, the quotient is[tex]9x^3 + 4x^2 + 5x + 2[/tex].

We have been given a line on coordinate plane. We are asked to find the equation of our given line.
First of all, we will find slope of our given line using points [tex](-2,3)[/tex] and [tex](0,-1)[/tex] in slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], where,
[tex]y_2-y_1[/tex] = Difference between two y-coordinates,
[tex]x_2-x_1[/tex] = Difference between two x-coordinates of same y-coordinates.
Upon substituting our given values in slope formula, we will get:
[tex]m=\frac{-1-3}{0--2}[/tex]
[tex]m=\frac{-4}{0+2}[/tex]
[tex]m=\frac{-4}{2}[/tex]
[tex]m=-2[/tex]
Now, we will use slope-intercept form of equation [tex]y=mx+b[/tex], where,
m = Slope of line,
b = The y-intercept.
Upon looking at our given graph, we can see that y-intercept is [tex]-1[/tex].
Therefore our required equation would be [tex]y=-2x-1[/tex] and option D is the correct choice.

A radius is a0 the diameter
Answer:
Hence, A radius is half the diameter.
Step-by-step explanation:
The question is asked as:
A radius is [tex]a_0[/tex] the diameter.
i.e. what is the value of the constant [tex]a_0[/tex] such that the radius and the diameter are related to each other.
We know that:
The Radius is the length of the line through the center that touches a point on the edge of the circle.
The diameter is the length of the line through the center that touches two points on the edge of the circle.
Hence Radius is half the diameter.
so the value of [tex]a_0=\dfrac{1}{2}[/tex]
( Or we can say Diameter is twice the radius of the circle.
[tex]d=2r\\\\r=\dfrac{1}{2}d[/tex]
where d denotes the diameter of the circle and r denotes the radius of the circle ).
