graph of this equation x=3/5y
Answers
Step by step
Solve
3/5y = 1x
Divide both sides by 3/5 to isolate y
When you divide by a fraction, flip your fraction and multiply
3/5 * 5/3 y = 5/3 * 1x
y = 5/3x
There is no y intercept so your line passes through (0,0)
Your slope is 5/3, so from zero, you plot your point at rise 5 run 3, or up 5 and right 3, or x y pair ( 3, 5) and (0, 0)

What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

one sheet of paper in a notebook is 8 1/2 inches by 11. a smaller notebook has a similar shape, and its pages are 5 1/2 inches long. what is the width of the paper in the smaller notebook?
Answers
The width of the paper in the smaller notebook is 4 1/4 inches.
When two shapes are similar, the ratio of their corresponding sides are equal, and their corresponding angles are equal.
For two notebooks in the shape of a rectangle, the ratio of their lengths must be equal to the ratio of their widths.
If one sheet of paper in a notebook is 8 1/2 inches by 11, and the pages of the smaller similar notebook are 5 1/2 inches long, then the width of the paper in the smaller notebook is
11 inches / 5 1/2 inches = 8 1/2 inches / width of smaller notebook

Answers
There were three different treatments: erythropoietin, darbepoetin, and no treatment. This selection exemplifies the principle of randomization principle.
What is a treatment?In experiments, the word treatment refers to the use of a specific medicine, therapy, or condition that is controlled by the research to test the effect of the treatment on subjects. For example, if the researcher wants to find out the ideal amount of water for a plant to grow, the treatment would be the amount of water.
In the case presented, there are three treatments:
Erythropoietin (epo) three times a week.Darbepoetin once a week for several weeks.No treatment.What principle of experimental design does that address?Randomization is the principle applied because the subjects are selected randomly for each of the groups and this reduces bias.

The simplified expression is [tex]x^8[/tex].
What is exponent?Exponent is the power of the variable or constant to which it is raised.
The expression 1 over x is denoted by 1/x.
The exponent of the obtained expression will be -8. So, the expression will be [tex](\frac{1}{x})^{-8}=\frac{1}{x^{-8}}[/tex].
The exponents of the denominator change from negative to positive when they move from denominator to numerator.

The probability that mn has a units digit of 1 = 2/5
What is Euler's theorem ?According to Euler's Theorem, if gcd(a,n) = 1, then a(n) 1. (mod n). The number of relatively prime integers in the range of 1, 2,..., n-1 is represented by the Euler totient function, or (n). This theorem is simply Fermat's little theorem when n is a prime.The remainder of a(m), when divided by a positive integer m that is relatively prime to a, is 1, according to Euler's Theorem. Because Fermat's Theorem is merely a special case of Euler's Theorem, this is the only way we can demonstrate Euler's Theorem. This is because (p)=p1 holds for a prime number p.By Euler's Theorem, we have that [tex]$a^{4} \equiv 1 \pmod {10}$[/tex] if [tex]$\gcd(a,10)=1$[/tex] Hence[tex]$m=11,13,17,19$,[/tex][tex]$n=2000,2004,2008,2012,2016$[/tex] work.
Also note that [tex]$11^{\text{any positive integer}}\equiv 1 \pmod {10}$[/tex] because [tex]$11^b=(10+1)^b=10^b+10^{b-1}1+...+10(1)+1$[/tex], and the latter[tex]$\pmod {10}$[/tex]is clearly [tex]$m=11$[/tex], [tex]$n=1999,2001,2002,2003,2005,...,2018$[/tex] work (not counting multiples of 4 as we would be double counting if we did).
We can also note that [tex]$19^{2a}\equiv 1 \pmod {10}$[/tex] because[tex]$19^{2a}=361^{a}$[/tex], and by the same logic as why [tex]$11^{\text{any positive integer}}\equiv 1 \pmod {10}$[/tex]we are done. Hence [tex]$n=2002, 2006, 2010, 2014, 2018$[/tex] and [tex]$m=19$[/tex] work (not counting any of the aforementioned cases as that would be double counting).
We cannot make any more observations that add more[tex]$m^n$[/tex] with unit digit [tex]$1$[/tex], hence the number of [tex]$m^n$[/tex] that have units digit one is [tex]$4\cdot 5+1\cdot 15+1\cdot 5=40$.[/tex] And the total number of combinations of an element of the set of all [tex]$m$[/tex]and an element of the set of all n is [tex]$5\cdot 20=100$[/tex].

a binomial experiment with probability of success and trials is conducted. what is the probability that the experiment results in or more successes? do not round your intermediate computations, and round your answer to three decimal places. (if necessary, consult a list of formulas.)
Answers
The probability that the experiment results in 9 or more successes = 0.0676
A binomial distribution is given by,
P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ ,
where p is the probability of success and x is the random variable for success in n trials.
A binomial experiment has only two outcomes- success or failure.
Here, the number of trials, n = 10
Probability of success = 0.63
The probability for 9 or more success = P( X = 9, 10)
= P (X = 9) + P(X = 10)
So P( X = 9) = ¹⁰C₉ (0.63)⁹ (1-0.63)¹⁰⁻⁹
= 10 x 0.0156 x 0.37
= 0.05772
and P(X = 10) = ¹⁰C₁₀ (0.63)¹⁰(1-0.63)¹⁰⁻¹⁰
= 1 x 0.009849 x 1
= 0.009849
Hence probability for 9 or more success = 0.05772 + 0.009849
= 0.067569

Consider the line y = = 8 x-4. Find the equation of the line that is parallel to this line and passes through the point (7, -2). Find the equation of the line that is perpendicular to this line and passes through the point (7, -2).
Answers
Answer: y=8x-58
Step-by-step explanation:
1. find the slope
Since the new line is parallel to the first one that means the slope of 8x will remain the same.
2. plug it into the point slope formula y-y1=m(x-x1)
which would look like
y-(-2)=8(x-7)
3. solve for y
y-(-2)=8(x-7)
y+2=8x-56
y=8x-58
Parallel slope = 8
Perpendicular slope = -1/8
Use point slope. Use point and respective slope.
y-y1= m(x-x1)
y+2 = 8(x-7)
y+2 = 8x - 56
y= 8x - 58 (parallel equation)
y-y1= m(x-x1)
y+2 = -1/8(x-7)
y+2 = -1/8x +7/8
y= -1/8x - 11/8 (perpendicular equation)

Point(2,8) , (4,7.5) rise over run so what's the answer
Answers
The slope of the line with the given coordinates (2,8) and (4,7.5) is -0.25.
What is the slope of the line with the given coordinates?Slope is simply expressed as change in y over the change in x.
Rise over run.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Given the data in the question;
Point 1( 2,8) )
x₁ = 2y₁ = 8Point 2( 4,7.5 )
x₂ = 4y₂ = 7.5To find the slope, plug the given x and y values into the slope formula and simplify.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 7.5 - 8 )/( 4 - 2 )
Slope m = ( -0.5 )/( 2 )
Slope m = -0.5 / 2
Slope m = -0.25
Therefore, the slope of the line is -0.25.
