Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line.
Answers
Answer:
(a). y = 3x - 11 ; (b). y = [tex]-\frac{1}{3}[/tex] x - 1
Step-by-step explanation:
Parallel lines have the same slopes
Slopes of perpendicular lines are opposite reciprocals.
(3, - 2)
The slope of given line is 3
(a). Equation of ║ line is
y + 2 = 3(x - 3)
y = 3x - 11
(b). Slope of perpendicular line is [tex]-\frac{1}{3}[/tex]
y + 2 = [tex]-\frac{1}{3}[/tex] (x - 3)
y = [tex]-\frac{1}{3}[/tex] x - 1
The required equation of a line parallel to the line will be y = 3x - 7
The required equation of the perpendicular line is y = -1/3 - 7
Using the coordinate points to get the equation of the line (1, -4) and (2, -1)
The standard form of the equation is expressed as y = mx + b
m is the slope
b is the y-intercept
Get the slope:
m = y2-y1/x2-x1
m = -1+4/2-1
m = 3/1
m = 3
Get the y-intercept
-4 = 3(1) + b
b = -4-3
b = -7
The required equation of a line parallel to the line will be y = 3x - 7
For the equation of the line perpendicular, the slope of the line will be -1/3
The required equation of the perpendicular line is y = -1/3 - 7

If P is the incenter of triangle JKL find each measure
Answers
Answer:
Check explanation section (check the attached file for the diagram to the question).
Step-by-step explanation:
Without mincing words let's dive straight into the solution to the question/ problem above.
From the question above, we have that the point p = the point at which the bisecting angle of the triangles meets, that is the term known as incenter.
So, we have that; 7x - 6 = 5x + 4. Hence;
2x = 10; x = 5°.
Thus, the angle 5x + 4 = which is the angle KJP = 5x + 4. Recall from above that x = 5°.
Hence; 5x + 4 = 5(5) + 4 = 25 - 4 = 29°.
Also, the angle 7x - 6 = which is the angle KJP = 7x - 6. Recall from above that x = 5°.
Therefore, 7x - 6 = 7(5) - 6 = 35 - 6 = 29°.
The angle KJP + the angle LJP= the angle KJL.
Therefore, the angle KJL = 29° + 29° = 58°.
Angle KJL = 130 - ( angle KJL) - (angle KJL).
The angle KJL = 130° - ( 58°) - (52° ) = 70°

Answers
Answer:
Solving the equation [tex]a (c -b) = d[/tex] for c we get [tex]\mathbf{c=\frac{d+ba}{a} }[/tex]
Step-by-step explanation:
We need to solve the equation [tex]a (c -b) = d[/tex] for c
Solving the given equation:
[tex]a (c -b) = d[/tex]
Divide both sides by a
[tex]\frac{a(c-b)}{a}=\frac{d}{a}\\c-b=\frac{d}{a}[/tex]
Adding b on both sides
[tex]c-b+b=\frac{d}{a}+b\\c=\frac{d}{a}+b\\c=\frac{d+ba}{a}[/tex]
So, solving the equation [tex]a (c -b) = d[/tex] for c we get [tex]\mathbf{c=\frac{d+ba}{a} }[/tex]

(a) Find the mean, variance, and standard deviation of the probability distribution
Find the mean of the probability distribution
(Round to one decimal place as needed.)
Answers
Answer:
a) The mean of the probability distribution = 0.6
b) The variance of the probability distribution = 0.3
c) The standard deviation of the probability distribution = 0.5
Step-by-step explanation:
a) Data and Calculations:
number of dogs per household in a small town
Dogs Probability Expected Mean Diff Mean Diff.
Value Squared
0 0.650 0 -0.569 0.32376
1 0.216 0.216 -0.353 0.12461
2 0.087 0.174 -0.395 0.15603
3 0.026 0.078 -0.491 0.24108
4 0.014 0.056 -0.513 0.26317
5 0.009 0.045 -0.524 0.27458
The mean = 0.569 (Sum of expected value)
Variance = mean of squared differences = 0.27665 (1.38323/5)
Standard deviation = square root of variance = 0.526 = 0.5
The mean, variance and standard deviation of the considered probability distribution are evaluated to be:
Mean of the distribution = 0.569Variance of the distribution = 0.923 approxStandard deviation of the distribution = 0.96 approxHow to find the mean (expectation) and variance of a random variable?Supposing that the considered random variable is discrete, we get:
[tex]Mean = E(X) = \sum_{\forall x_i} f(x_i)x_i\\\\Variance = Var(X) = (\sum_{\forall x_i} f(x_i)x^2_i) - (E(X))^2\\[/tex]
As standard deviation is positive root of variance, thus,
[tex]\sigma = \sqrt {Var(X)}[/tex]
where [tex]x_i; \: \: i = 1,2, ... ,n[/tex] is its n data values
and [tex]f(x_i)[/tex] is the probability of [tex]X = x_i[/tex]
For this case, let we suppose that:
X = number of dogs per household in the considered town.
Then we have the probability distribution for values of X as:
Number of dogs Probability
0 0.650
1 0.216
2 0.087
3 0.026
4 0.014
5 0.009
Thus, we get:
Mean of X : E(X) = [tex]0 \times 0.650 + 1 \times 0.216 + 2 \times 0087 + 3 \times 0.026 + 4 \times 0.014 + 5 \times 0.009 = 0.569[/tex]
Variance of X:
Var(X) =
[tex](0^2 \times 0.650 + 1^2 \times 0.216 + 2^2 \times 0.087 + 3^2 \times 0.026 + 4^2 \times (0.014)\\ + 5^2 \times (0.009)) - (0.569)^2 \approx 0.923[/tex]
Standard deviation of X = [tex]\sigma = \sqrt {Var(X)} \approx \sqrt{0.923} \approx 0.96[/tex]
Thus, the mean, variance and standard deviation of the considered probability distribution are evaluated to be:
Mean of the distribution = 0.569Variance of the distribution = 0.923 approxStandard deviation of the distribution = 0.96 approxLearn more about expectation of a random variable here:

Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a + b )( a − b ) where a = t and b = 6

how many real solutions does x²+8x+20=0 have?
Answers
Answer:
No real solutions
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
D = b² - 4ac
Plug in b, a, and c:
D = b² - 4ac
D = (8)² - 4(1)(20)
D = 64 - 80
D = -16
Since the discriminant is negative, there are no real solutions
Since the solution is a complex value, hence the equation has no real solutions
Givne the quadratic expression x²+8x+20 = 0
Factorizing the function
x²+8x+20 = 0
x = -8±√8²-4(20)/2
x = -8±√64-80/2
x = -8±√-16/2
x = -8±4i/2
x = -4±2i
Since the solution is a complex value, hence the equation has no real solutions
