Answer:
Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:
2, 2, 3, 4, 6, 6, 9.
7 numbers total.
2 + 2 + 3 + 4 + 6 + 6 + 9 = 32
32 ÷ 7 = 4.57
The mean would be 4.57.
Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:
2, 2, 3, 4, 6, 6, 9
2, 3, 4, 6, 6
3, 4, 6
4
4 would be the median.
Mode- the largest number on the data.
Range- subtract the mode (largest number) from the smallest number to get range. For example:
2, 2, 3, 4, 6, 6, 9
9 - 2 = 7
7 would be the range.

Complete the number sentence:
7 2/5 + ___ = 8
Answer:
3/5Step-by-step explanation:
7 2/5 + ___ = 8
(As on left side there is 7 2/5 on right side it will be -7 2/5)
=> ____ = 8 - 7 2/5
(Converting - 7 2/5 to improper fraction that is -37/5)
=> ____ = 8 - 37/5
=> ____ = (40 - 37)/5
=> ____ = 3/5
Hence,
3/5 is the answer

Compare the numbers 6x10-6 to 2x10-8.
Which number has the greater value?
Which number has the lesser value?
How many times greater is the greater number?
Answer:
6×10-6 have greater value than 2×10-8
Step-by-step explanation:
6×10-6
60-6
=54
And
2×10-8
20-8
=12
Thus, 6×10-6 had the greatest value by 42 more than 2×10-8
6×10-6 have greater value than 2×10-8
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Compare the numbers 6 x 10⁻⁶ and 2 x 10⁻⁸.
Then the numbers can be written as,
⇒ 6 x 10⁻⁶ and 2 x 10⁻⁸
⇒ 600 x 10⁻⁸ and 2 x 10⁻⁸
The number 600 x 10⁻⁸ times greater than the number 2 x 10⁻⁸ will be
⇒ 600 x 10⁻⁸ / 2 x 10⁻⁸
⇒ 300
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.

How much money must you set aside at age 40 to accumulate retirement funds of $100,000 at age 65, assuming a rate of interest of 7 percent?
Answer:
$18,424.92
Step-by-step explanation:
Assuming this is compound interest, we'll have to use this formula
A = P(1 + r)ⁿ
A = Final amount (100,000)
P = Starting amount (?)
r = Rate (.07)
n = Years (?)
65 - 40 = 25
This means you will save for 25 years, making n = 25
So far, our equation looks like this: 100,000 = P(1.07)²⁵
To isolate the variable, P, divide both sides by 1.07²⁵
100,000/1.07²⁵ = P(1.07)²⁵/1.07²⁵
P = 18,424.917752223962
You would need to set aside around $18,424.92 if you want to accumulate $100,000 in 25 years with 7% compound interest rate.

Answer:
Three non-collinear points determine a plane.
Step-by-step explanation:
This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is
In a sample, 11 out of 25 marbles are
green. Predict approximately how
many green marbles are in a box of
100 marbles.
Answer:
11x4=44
Step-by-step explanation:
Cus 11/25, change the 25 to 100 by multiplying by 4 so you also have to multiply 11 by 4 too and yeah...answer
Answer:44
Step-by-step explanation: You want to multiply your denominator by a certain number that will turn it into 100. In this case 25 time 4 is 100. so now that you've multiplied your denominator you also need to multiply your numerator by 4. So the next step would be 11 times 4, which is 44.

How many zeros are in the product of any nonzero whole number
Answer:
2 zeros for odd numbers less than 10
3 zeros for even numbers less than 10
Step-by-step explanation:
Non-zero whole numbers less than 10 are;
1, 2, 3,4, 5, 6, 7, 8, and 9
The odd numbers include:
3, 5, 7, and 9
The product of 500 and any of these numbers will contain 2 zeros, the ones in the number 500.
On the other hand, the even numbers include;
2, 4, 6, and 8
The product of 500 and any of these numbers will contain 3 zeros of which 2 are the ones in the number 500 and 1 zero is as a result of multiplying 5 by an even number.
Ten less than the product of 5 and the difference of a number and one is twice the number. What is the number?
Answer: 5
Step-by-step explanation:
5(n-1)-10=2n
5n-5-10=2n
5n-2n = 10+5
3n = 15
n = 15/3
n = 5
Find the flux of the vector field F = 〈e-z,4z,6xy) across the curved sides of the surface S = {(x,y,z): z= cos y, lys π, 0sxs4} . Normal vectors point upward. Set up the integral that gives the flux as a double integral over a region R in the xy-plane.
I'll go ahead and assume you meant to say that S is the surface given by
[tex]S = \left\{(x,y,z) \mid z = \cos(y)\text{ with } 0\le y\le \pi\text{ and }0\le x\le4\right\}[/tex]
This immediately gives us a parameterization for the surface,
[tex]\vec r(x, y) = \left\langle x, y, \cos(y)\right \rangle[/tex]
The upward-pointing normal vector to this surface is then
[tex]\vec n = \dfrac{\partial\vec r}{\partial x} \times \dfrac{\partial\vec r}{\partial y} = \left\langle0,\sin(y),1\right\rangle[/tex]
Then the flux of [tex]\vec F(x,y,z) = \left\langle e^{-z}, 4z, 6xy\right\rangle[/tex] across S is
[tex]\displaystyle \iint_S \vec F(x,y,z)\cdot\mathrm d\vec s = \int_0^4\int_0^\pi \vec F(x,y,\cos(y))\cdot\vec n\,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi \left\langle e^{-\cos(y)},4\cos(y),6xy\right\rangle \cdot \left\langle0,\sin(y),1\right\rangle \,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi (4\sin(y)\cos(y)+6xy)\,\mathrm dy\,\mathrm dx \\\\ = 2 \int_0^4\int_0^\pi (\sin(2y) + 3xy)\,\mathrm dy\,\mathrm dx = \boxed{24\pi^2}[/tex]

how to differentiate ?
Use the power, product, and chain rules:
[tex]y = x^2 (3x-1)^3[/tex]
• product rule
[tex]\dfrac{\mathrm dy}{\mathrm dx} = \dfrac{\mathrm d(x^2)}{\mathrm dx}\times(3x-1)^3 + x^2\times\dfrac{\mathrm d(3x-1)^3}{\mathrm dx}[/tex]
• power rule for the first term, and power/chain rules for the second term:
[tex]\dfrac{\mathrm dy}{\mathrm dx} = 2x\times(3x-1)^3 + x^2\times3(x-1)^2\times\dfrac{\mathrm d(3x-1)}{\mathrm dx}[/tex]
• power rule
[tex]\dfrac{\mathrm dy}{\mathrm dx} = 2x\times(3x-1)^3 + x^2\times3(3x-1)^2\times3[/tex]
Now simplify.
[tex]\dfrac{\mathrm dy}{\mathrm dx} = 2x(3x-1)^3 + 9x^2(3x-1)^2 \\\\ \dfrac{\mathrm dy}{\mathrm dx} = x(3x-1)^2 \times (2(3x-1) + 9x) \\\\ \boxed{\dfrac{\mathrm dy}{\mathrm dx} = x(3x-1)^2(15x-2)} [/tex]
You could also use logarithmic differentiation, which involves taking logarithms of both sides and differentiating with the chain rule.
On the right side, the logarithm of a product can be expanded as a sum of logarithms. Then use other properties of logarithms to simplify
[tex]\ln(y) = \ln\left(x^2(3x-1)^3\right) \\\\ \ln(y) = \ln\left(x^2\right) + \ln\left((3x-1)^3\right) \\\\ \ln(y) = 2\ln(x) + 3\ln(3x-1)[/tex]
Differentiate both sides and you end up with the same derivative:
[tex]\dfrac1y\dfrac{\mathrm dy}{\mathrm dx} = \dfrac2x + \dfrac9{3x-1} \\\\ \dfrac1y\dfrac{\mathrm dy}{\mathrm dx} = \dfrac{15x-2}{x(3x-1)} \\\\ \dfrac{\mathrm dy}{\mathrm dx} = \dfrac{15x-2}{x(3x-1)} \times x^2(3x-1)^3 \\\\ \dfrac{\mathrm dy}{\mathrm dx} = x(15x-2)(3x-1)^2[/tex]
