Answer:
Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]

What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Consider the equation: x^2=-8x-7
1) Rewrite the equation by completing the square. Write it as (x+c)^2=d or (x-c)^2=d
Here the equation: x^2=-8x-7
x^2 + 8x + 7 = 0
Where a = 2, b = 8 , c = 7
(x+c)^2 = d or (x + 7)^2 = 16
(x-c)^2=d or (x - 7)^2 = 16
2) The solutions to the equation are;

Compare: 2/3×(9+12)◯15×2/3
Answer:
[tex]\frac{2}{3}[/tex] (9 + 12) > 15 * [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] (9 + 12) = [tex]\frac{2}{3}[/tex] * 21 = 2 * 7 = 14
15 * [tex]\frac{2}{3}[/tex] = 5 * 2 = 10

What are the dependent and independent
variables?
Answer:
The dependent variable depends on the value of some other number also known as the independent variable. Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.
