The Buddha taught that just as individual states had laws, there was a universal law. Each person's station in life was a reflection of their karma, or the cumulative extent to which they had followed or broken the universal law in previous lives. Chinese leaders began to appoint skilled bureaucrats rather than solely employing hereditary officeholders, and Confucian thinkers held that people became fully developed members of society through a process of education, rather than simply by noble birth.
Help me with these questions 15points
if f(x)=mx+b what are the values of m and b
The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.
example 1
y = mx + b
m = slope b = y-intercept
y = 3x - 1
m = 3 and b = -1
example 2
y = b + mx
b = y-intercept m = slope
y = 5 - 1/2x
m =- 1/2 and b = 5

The simplified expression is:
[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]
[tex]=\frac{2}{5}y+\frac{1}{5}x-0.2y-6-2[/tex]
[tex]\mathrm{Group\:like\:terms}[/tex]
[tex]=\frac{2}{5}y-0.2y+\frac{1}{5}x-6-2[/tex]
Add similar elements
[tex]=0.2y+\frac{1}{5}x-6-2[/tex]
[tex]=0.2y+\frac{x}{5}-6-2[/tex]
[tex]=0.2y+\frac{x}{5}-8[/tex]
[tex]=0.2y+0.2x-8[/tex]
Thus, the simplified expression is:
[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]
Jordan bought a new sketchbook with 150 pages in it for art class. Each day, he uses 2 pages for assignments and sketchings. Which equation represents the total number of blank pages, p, remaining after d days?
A. p= -2d - 150
B. p= -2d + 150
C. p= 2d - 150
D. p= 2d + 150
Answer:
B.
Step-by-step explanation:
He uses two pages each day so they would be negative two and he had positive 150 pages, so the answer would be B.

What is the standard deviation? Round your answer to two decimal places. s_x\approxs x ≈s, start subscript, x, end subscript, approximately equals \text{kg}kgstart text, k, g, end text
Answer:
The standard deviation of the weight, σ, is approximately 4.73 kg
Step-by-step explanation:
The weights of the six puppies are;
[tex]x_i[/tex] = 1, 2, 7, 7, 10, and 15
The number of puppies, n = 6
Therefore, we have;
The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7
The standard deviation, σ, is given as follows;
[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}[/tex]
By substituting, we have;
[tex]\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}[/tex]
Simplifying gives;
[tex]\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}[/tex]
[tex]\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582[/tex]
The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.

6x - 8-10 = 2 (2x+8) + 2x + 2
Answer:
0 = 36 (No Solution)
Step-by-step explanation:
6x - 8 - 10 = 2(2x + 8) + 2x + 2
Add -8 and -10 = -18
6x + -18 = 2(2x + 8) + 2x + 2
Distributing. 2 x 2x & 2 x 8
6x + -18 = 4x + 16 + 2x + 2
Combine light terms.
6x + -18 = 6x + 18
Add 18 to both sides.
6x = 6x + 36
Subtract 6x
0 = 36
Final Answer: 0 = 36 (No Solution)
statistics what is meant by re-expressing or transforming data? what is the purpose of re expressing or transforming data
Re-expressing data means making the facts more appropriate for evaluation by our methods.
We can not use a linear version until the connection among the 2 variables is linear. Often re-expression (transformation) can save the day, straightening bent relationships in order that we are able to suit and use a easy linear version.
• Two easy approaches to re-specific facts are with logarithms and reciprocals.
• Re-expressions may be visible in regular life— all and sundry does it.
We can re-specific gas performance as gallons in step with hundred miles (a reciprocal) and get rid of the bend in the authentic scatterplot.
Therefore, re-expressing data means making the facts more appropriate for evaluation by our methods.

The difference between 1/3 of a certain number and 1/4 of the same number is 3.
What is the number?
24. 36. 48. 60. or 72?
Answer:
36
Step-by-step explanation:
Let the required number be x.
[tex] \frac{1}{3} \: of \: x = \frac{1}{3}x = \frac{x}{3} \\ \\ \frac{1}{4} \: of \: x = \frac{1}{4}x = \frac{x}{4} \\ \\ according \: to \: the \: given \: condition \\ \\ \frac{x}{3} - \frac{x}{4} = 3 \\ \\ \frac{4x - 3x}{3 \times 4} = 3 \\ \\ \frac{x}{12} = 3 \\ \\ x = 12 \times 3 \\ \\ \huge \red{ \boxed{ x = 36}}[/tex]
The number is 36.
Given that,
The difference between one-third of a certain number and one-fourth of the same number is 3.Here we assume the number be x.
Based on the above information, the calculation is as follows:
[tex]\frac{x}{3} - \frac{x}4} = 3 \\\\\frac{4x - 3x}{12} = 3\\\\x = 36[/tex]
