Answer:
a) 50
Step-by-step explanation:
The variance will not change as all the observations are increased uniformly.
Proof:
Variance formula:
[tex]s^{2} = \frac{\sum x_i^{2} }{n} -\frac{(\sum x_i)^{2} }{n^{2} }[/tex]
When the obervations are inc by 20,
[tex]s_1^{2} = \frac{\sum (x_i + 20)^{2} }{n} -\frac{(\sum (x_i + 20))^{2} }{n^{2} }\\\\=\frac{\sum(x_i^{2} + 2*20*x_i + 20^{2} )}{n} - \frac{(\sum x_i +20n)^{2} }{n^{2} } \\\\=\frac{\sum x_i^{2} + 40\sum x_i + 20^{2}n }{n} - \frac{(\sum x_i)^{2} +2*20n\sum x_i + 20^{2} n^{2} }{n^{2} } \\\\= \frac{\sum x_i^{2}}{n} - \frac{(\sum x_i)^{2}}{n^{2} } +\frac{40\sum x_i}{n} + 20^{2} - \frac{40\sum x_i}{n} - 20^{2}\\\\s_1^{2}= \frac{\sum x_i^{2}}{n} - \frac{(\sum x_i)^{2}}{n^{2} }\\\\=s^{2}[/tex]
Therefore variance doesn't change
Antiderivative with the equation
The antiderivative of the function is f(x) = 2x + 5x³ + 2x⁶ - 9.
Find an antiderivative of f(x)To find an antiderivative of f(x), we can integrate each term of f'(x) individually.
Given:
f'(x) = 2 + 15x² + 12x⁵
To integrate 2, we get:
∫2 dx = 2x + C₁, where C₁ is the constant of integration.
To integrate 15x², we get:
∫15x² dx = 5x³ + C₂, where C₂ is another constant of integration.
To integrate 12x⁵, we get:
∫12x⁵ dx = 2x⁶ + C₃, where C₃ is another constant of integration.
Putting it all together, the antiderivative of f(x) is:
f(x) = 2x + 5x³ + 2x⁶ + C,
where C = C₁ + C₂ + C₃ represents the constant of integration.
To find the specific value of C, we are given that f(1) = 0. Substituting x = 1 into the antiderivative equation:
0 = 2(1) + 5(1)³ + 2(1)⁶ + C,
0 = 2 + 5 + 2 + C,
0 = 9 + C.
Therefore, C = -9.
The final expression for f(x) is:
f(x) = 2x + 5x³ + 2x⁶ - 9.

OThe presence of identical fossil plants in both Antarctica and Australia, within the same rock formations, supports the hypothesis of a supercontinent and the process of plate tectonics by providing evidence of past land connections and the subsequent separation of continents due to tectonic activity.
How to explain the informationThe presence of identical fossil plant species in rock formations of both Antarctica and Australia suggests that these two regions were once connected geographically. The similarity in the fossil record indicates that the plants existed in a shared ecosystem or environment at some point in the past.
The geological formations in which the fossil plants are found can provide further evidence. If the rock layers containing the fossils can be matched across Antarctica and Australia, it suggests that these regions were once part of the same landmass. This correlation supports the idea of a supercontinent.

cups of juice.
Which is the best estimate for the amount of juice Barry made?
The best estimate for the amount of juice Barry made is 235 cups.
In this question, Jessica and Barry squeezed oranges for juice. Jessica squeezed 235 cups of juice. Barry made 14 cups less than Jessica. Barry estimated that Jessica squeezed about 212 cups of juice. We need to find the best estimate for the amount of juice Barry made.
Let's begin by finding the amount of juice Barry actually made. Barry made 14 cups less than Jessica, which means he made: 235 - 14 = 221 cups of juice.
Now, let's compare this to Barry's estimate. Barry estimated that Jessica squeezed about 212 cups of juice. Since Jessica actually squeezed 235 cups of juice, her estimate was too low by:235 - 212 = 23 cups.
So, we can apply this error to Barry's estimate to get a better estimate for the amount of juice he made. If Barry's estimate was 212 cups, and he underestimated by 23 cups, then he actually made:212 + 23 = 235 cups of juice. Therefore, the best estimate for the amount of juice Barry made is 235 cups.

Han make sparkling juice by mixing 1. 5 liter of juice and 500 milliliter of sparkling water
Han will have 2 liters (or 2000 milliliters) of sparkling juice after combining 1.5 liters of juice and 500 milliliters of sparkling water.
To make sparkling juice, Han mixes 1.5 liters of juice and 500 milliliters of sparkling water.
To add the quantities together, we need to convert the units to the same measurement. We can convert the liters to milliliters since 1 liter is equal to 1000 milliliters.
1.5 liters is equal to 1.5 x 1000 = 1500 milliliters.
Now we have 1500 milliliters of juice and 500 milliliters of sparkling water.
To find the total quantity of the sparkling juice, we add the volumes of juice and sparkling water together:
1500 milliliters + 500 milliliters = 2000 milliliters
Therefore, Han will have a total of 2000 milliliters (or 2 liters) of sparkling juice by mixing 1.5 liters of juice and 500 milliliters of sparkling water.

For two invertible n by n matrices A, B,

is the following always true?
"rank(AB) = n"
If so,
I wonder how we can prove it.
If not,
I'd appreciate you if you show me a counterexample.
Thank you in advance.
The statement "rank(AB) = n" is not always true for invertible n by n matrices A and B with rank(A) = rank(B) = n.
Counterexample:
Consider the following counterexample:
[tex]A = \begin{bmatrix} 1 & 0 \ 0 & 1 \end{bmatrix}\\B = \begin{bmatrix} 1 & 0 \ 0 & 0 \end{bmatrix}[/tex]
Both matrices A and B are invertible, as they are both identity matrices. However, when we multiply them together, we get:
[tex]AB = \begin{bmatrix} 1 & 0 \ 0 & 0 \end{bmatrix}[/tex]
The rank of AB is 1, not n. In this case, n = 2, but rank(AB) = 1. Therefore, the statement "rank(AB) = n" is not always true for all invertible n by n matrices A and B with rank(A) = rank(B) = n.
In general, the rank of the product AB is less than or equal to the minimum of the ranks of A and B. So, in order for rank(AB) to be equal to n, both A and B need to have rank n individually, but that does not guarantee the rank of their product to be n as well.

1. A student determines that one solution to a system of quadratic-quadratic equations is (2.1).
Determine the value of n if the equations are:
4x² - my=10
mx² + ny=20
Answer: -4
The value of n is approximately -0.327.
To determine the value of n, we can substitute the given solution (x = 2.1) into the system of equations:
4x² - my = 10 ...(1)
mx² + ny = 20 ...(2)
Substituting x = 2.1 into equation (1), we get:
4(2.1)² - my = 10
8.4 - my = 10
-my = 10 - 8.4
-my = 1.6
Now, substituting x = 2.1 into equation (2), we get:
m(2.1)² + ny = 20
4.41m + ny = 20
Since we already have an expression for -my from equation (1), we can substitute it into equation (2):
4.41m + (-1.6) = 20
4.41m - 1.6 = 20
4.41m = 20 + 1.6
4.41m = 21.6
To solve for m, we divide both sides by 4.41:
m = 21.6 / 4.41
m ≈ 4.9
Now that we have the value of m, we can substitute it back into equation (1) to solve for n:
4(2.1)² - 4.9y = 10
8.4 - 4.9y = 10
-4.9y = 10 - 8.4
-4.9y = 1.6
Finally, to solve for y, we divide both sides by -4.9:
y = 1.6 / -4.9
y ≈ -0.327
Consequently, n has a value of roughly -0.327.

£1
Exchange rate
= €1.13
Gabby can get €23.73 for £21 when using the exchange rate of £1 = €1.13.
To calculate how many euros Gabby can get for £21, we need to use the exchange rate of £1 = €1.13.
To find the number of euros, we multiply the amount in pounds (£21) by the exchange rate (€1.13):
£21 * €1.13 = €23.73
Therefore, Gabby can get €23.73 for £21 when using the exchange rate of £1 = €1.13.
This means that for every pound exchanged, Gabby will receive €1.13. So, by multiplying the amount in pounds (£21) by the exchange rate (£1 = €1.13), we can determine the equivalent amount in euros.
It's important to note that exchange rates can fluctuate, and the rate provided here is just an example.

Scores on the Wechsler Adult Intelligence Scale for the 20 to 34 age group are approximately Normally distributed with mean 110 and standard deviation 15. How high must a person score to be in the top 4% of all scores? (Round your answer to the nearest whole number, if necessary.)
Answer:
The person must score 136 to be in the top 5% of all scores in wechsler adult intelligence scale.
Step-by-step explanation:
What is defined as the normal distribution?
A normal distribution is a data set arrangement in which the majority of values cluster inside the center of the range and the remainder taper off symmetrically toward any extreme.
A histogram inside a normal distribution curve is sometimes used to design the curve.
The formula for the normal distribution is;
z = (x - μ)/σ
where,
z = z- score, taken fro table
Mean μ = 110
Standard deviation σ = 15
Sample mean x.
If we want to be in the top 5%, we must outperform 95% of the remaining scores. So we must investigate.
In with us standard normal probability table, look up 0.95 and get the Z score that corresponds to that.
z = 1.7
Put the value in formula ad find x.
1. 7 = (x - 110)/15
x = 25.5 + 110
x = 135.5
x = 136 (whole number)
Thus, the person must score 136 to be in the top 5% of all scores in wechsler adult intelligence scale.
when 24/5and another number are added together the answer is 9. what is the number
The number we're looking for, which when added to 24/5 results in 9, is 21/5 or 4.2 in decimal form.
Let's solve the equation: 24/5 + x = 9, where x represents the unknown number we're trying to find.
To isolate x, we'll start by subtracting 24/5 from both sides of the equation:
x = 9 - 24/5
To add these two fractions, we need a common denominator. The denominator of 9 is 1, and the denominator of 24/5 is 5. To find a common denominator, we multiply 1 by 5:
x = (9 * 5)/5 - 24/5
This gives us:
x = 45/5 - 24/5
Now we can combine the fractions with the same denominator:
x = (45 - 24)/5
Simplifying the numerator:
x = 21/5
Therefore, the number we're looking for is 21/5. In decimal form, it can be written as 4.2.

F(x)=square root of 9-kx^2/k show your work
Sure! Here’s the solution:
F(x)=k9−kx2
First, let’s square both sides to get rid of the square root:
F(x)2=k9−kx2
Now, let’s multiply both sides by k to isolate the term with x^2:
kF(x)2=9−kx2
Next, let’s move all terms to one side of the equation:
kF(x)2+kx2=9
Finally, let’s factor out x^2:
x2(k+kF(x)2)=9
And solve for x^2:
x2=k+kF(x)29
Answer:
√((9 - kx^2) / k)Step-by-step explanation:
To show the work for evaluating the function f(x) = √(9 - kx^2) / k, we can follow these steps:
Step 1: Simplify the expression under the square root:9 - kx^2
Step 2: Divide the expression by k:(9 - kx^2) / k
Step 3: Take the square root of the expression:√((9 - kx^2) / k)
Note: It is important to consider any domain restrictions or assumptions about the values of k and x that would make the expression valid. For example, if k is negative, the expression would have an imaginary result.Find x intercepts y=(x+3) (6x-2)
Answer:
x = - 3 , x = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
to find the x- intercepts let y = 0 , that is
(x + 3)(6x - 2) = 0
equate each factor to zero and solve for x
x + 3 = 0 ( subtract 3 from both sides )
x = - 3
6x - 2 = 0 ( add 2 to both sides )
6x = 2 ( divide both sides by 6 )
x = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
the x- intercepts are then x = - 2 and x = [tex]\frac{1}{3}[/tex]
A 18-foot ladder leaning against a building forms an 22angle with the side of the building How far is the base of the ladder from the base of the building?
Answer:
Using the sine function, we have:
sin(angle) = opposite / hypotenuse
sin(22 degrees) = opposite / 18 feet
We can rearrange this equation to solve for the opposite side (height of the building):
opposite = sin(22 degrees) * 18 feet
Calculating this:
opposite ≈ 6.24 feet
Therefore, the base of the ladder from the base of the building is approximately 6.24 feet.

Answer:
x-intercepts = (-3, 0) and (-1, 0)
y-intercept = (0, 3)
Vertex = (-2, -1)
Axis of symmetry: x = -2
Step-by-step explanation:
Given quadratic function:
[tex]g(x) = x^2 + 4x + 3[/tex]
[tex]\hrulefill[/tex]
x-interceptsTo find the x-intercepts of the given function g(x), set g(x) equal to zero and solve for x.
Set g(x) = 0:
[tex]x^2 + 4x + 3 = 0[/tex]
Factor the quadratic equation:
[tex]x^2+x+3x+3=0[/tex]
[tex]x(x+1)+3(x+1)=0[/tex]
[tex](x + 3)(x + 1) = 0[/tex]
Set each factor equal to zero and solve for x:
[tex]x + 3 = 0 \implies x = -3[/tex]
[tex]x + 1 = 0 \implies x = -1[/tex]
Therefore, the x-intercepts are at (-3, 0) and (-1, 0).
[tex]\hrulefill[/tex]
y-interceptTo find the y-intercept of g(x), substitute x = 0 and solve for y.
[tex]\begin{aligned}x=0 \implies y&= (0)^2 + 4(0) + 3\\y& = 0 + 0 + 3 \\y&= 3\end{aligned}[/tex]
Therefore, the y-intercept is at (0, 3).
[tex]\hrulefill[/tex]
VertexThe x-value of the vertex of a parabola in the form y = ax² + bx + c is x = -b/2a.
For the function g(x), a = 1, and b = 4.
Therefore, the x-coordinate of the vertex is:
[tex]\textsf{$x$-coordinate of vertex} = \dfrac{-b}{2a} = \dfrac{-4}{2(1)} = -2[/tex]
To find the y-coordinate of the vertex, substitute x = -2 into function g(x):
[tex]\begin{aligned}x=-2 \implies y &= (-2)^2 + 4(-2) + 3\\y& = 4-8 + 3 \\y&= -1\end{aligned}[/tex]
Therefore, the vertex is at (-2, -1).
[tex]\hrulefill[/tex]
Axis of symmetryThe axis of symmetry of a vertical parabola is the x-coordinate of its vertex.
As the x-coordinate of the vertex is -2, the axis of symmetry is x = -2.

Answer:
x = 6
Step-by-step explanation:
the diagonal AC divides the rectangle into 2 right triangles.
Consider the right triangle ABC with legs AB , BC and hypotenuse AC
using Pythagoras' identity in right triangle ABC
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² + BC² = AC² ( substitute values )
x² + (x + 2)² = (x + 4)² ← expand factors using FOIL
x² + x² + 4x + 4 = x² + 8x + 16
2x² + 4x + 4 = x² + 8x + 16 ( subtract x² + 8x + 16 from both sides )
x² - 4x - 12 = 0 ← in standard form
(x - 6)(x + 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
however , x > 0 , then x = 6

Paxton invests $4850 at 7.6%/a simple interest. If she wants the money to increase to $8000, how long will she need to invest her money?
Therefore, Paxton will need to invest her money for approximately 21.62 years to increase her investment from $4850 to $8000 at a simple interest rate of 7.6% per year.
To determine how long Paxton needs to invest her money in order for it to increase to $8000, we can use the formula for simple interest:
I = P * r * t
Where:
I = Interest earned
P = Principal (initial investment)
r = Interest rate per year (expressed as a decimal)
t = Time (in years)
Given that Paxton invests $4850 at an interest rate of 7.6% per year, we have:
4850 * 0.076 * t = 8000
Simplifying the equation:
369.8t = 8000
To find t, we divide both sides of the equation by 369.8:

What is a factored form?In Mathematics and Geometry, a factored form simply refers to a type of quadratic expression that is typically written as the product of two (2) linear factors and a constant.
In this scenario and exercise, we would complete the table above by showing the factored form and expanded form of each of the given expressions as follows;
x 12
2 2x 24
Note: 2x/2 = x.
24/2 = 12.
Next, we would write the expression 2x + 24 as a product as follows;
(2x + 24) = 2(x + 12).

what is e^0? and e^infinity?
e^0 equals 1. e^infinity is undefined.
In mathematics, e^0 is equal to 1. This is because any number raised to the power of 0 is always equal to 1. The number e, which is approximately equal to 2.71828, follows this rule as well. So, when e is raised to the power of 0, the result is 1.
On the other hand, e^infinity is undefined. As the exponent approaches infinity, the value of e^infinity increases without bound. It does not converge to a specific number or approach any finite value.
In calculus and mathematical analysis, this is expressed by saying that the limit of e^x as x approaches infinity is equal to infinity.
The exponential function e^x is a fundamental mathematical concept with many applications in various fields such as physics, engineering, and finance.
Understanding the behavior of this function at different values of x, including 0 and infinity, is important for solving equations, modeling growth and decay processes, and studying the properties of exponential functions.

If the base of a square building and an equilateral triangle building have the same perimeter, how do the areas of their floors compare?
Answer:
let, perimeter of square = 4a
where a = side of square
let, perimeter of the equilateral triangle = 3b
where b= side of triangle
therfore, 4a=3b
a/b = 3/4
area of the square = [tex]a^{2}[/tex]
are of the triangle = [tex]\frac{\sqrt{3} }{4} b^{2}[/tex]
dividing both the areas we get,
[tex]\frac{a^{2} }{\frac{\sqrt{3} }{4}b^{2} }[/tex]
[tex]a^{2}*\frac{4}{\sqrt{3} b^{2}}[/tex]
[tex]\frac{a^{2} }{b^{2} } * \frac{4}{\sqrt{3} }[/tex]
[tex]\frac{3^{2} }{4^{2} } * \frac{4}{\sqrt{3} }[/tex]
[tex]\frac{3\sqrt{3} }{4}[/tex]
