please help!!
Answer:
B
Step-by-step explanation:
Let’s first look at the y-intercept. Since the equation is in y = mx + b form, we know that m is the slope and b is the y-intercept, so the slope is 1/2 and the y-intercept is 2, or (0,2). We can narrow down our search by noticing that C and D don’t intersect (0,2). That leaves A and B.
The slope is calculated by (y_1 - y_2)/(x_1 - x_2) given points (x_1, y_1) and (x_2, y_2). The slope for A is (4-0)/(2-(-2)) = 4/4 = 1 and the slope for B is (2-0)/(0-(-4)) = 2/4 = 1/2. The slope of B matches the slope that we are looking for. So, the answer is B.

Answer:
Step-by-step explanation:
Step 1. Calculate the measures of center (mean and median)
Mean= Average= All data values added together then divided by number of data values.
Median = middle of numbers
0: 14: 35: 86: 37: 18: 59: 210: 3So, number of data values = 3+2+5+1+3+8+3+1= 26
Data values added together = 0 + 4+4+4+5+5+5+5+5+5+5+5+6+6+6+7+8+8+8+8+8+9+9+10+10+10= 165
165/26= 6.34615384
Average = 6.3
Median: Arrange numbers from least to greatest and eliminate one on both sides until you get a middle number:
0 , 4,4,4,5,5,5,5,5,5,5,5,6,6,6,7,8,8,8,8,8,9,9,10,10,10
The median is 6.
Step 2: Calculate range, IQR, and MAD
Range: Maximum- minimum
IQR: The IQR is the difference between Q3 and Q1.
Q1 is the middle value in the first half of the data set.
Q3 is the middle value in the second half of the data set.
MAD:
Take the average. Find the distance of each value from that mean (difference between data values and mean) , then take absolute value of that distance. Find the mean of those distances.Range: 10-0= 10
IQR: 3
MAD (population) : 1.9378698224852

Let u1 = [ 1 , 0 , -5 , 2 ]u2 = [ 0 , -1 , 2 , 5 ]u3 = [ 5 , 2 , 1 , 0 ]u4 = [ 2 , -5 , 0 , -1 ]AND Let W1 = Span {u1 , u2} , Let W2 = Span {u3 , u4}.write the vector y = 2 8 4 −6 as a sum of a vector in w1 and a vector in w2.
To write the vector y = [2, 8, 4, -6] as a sum of a vector in W1 and a vector in W2, we need to find the scalar multiples of vectors u1 and u2 that can be added to scalar multiples of vectors u3 and u4 to obtain y.
Let's find the scalar multiples of u1 and u2 first:
a1u1 + a2u2 = [2, 8, 4, -6]
We can solve this system of equations to find the values of a1 and a2:
a1 + 0 = 2 --> a1 = 2
0 + (-a2) = 8 --> a2 = -8
-5a1 + 2a2 = 4 --> -5(2) + 2(-8) = 4 --> -10 - 16 = 4 --> -26 = 4 (not satisfied)
2a1 + 5a2 = -6 --> 2(2) + 5(-8) = -6 --> 4 - 40 = -6 --> -36 = -6 (not satisfied)
Since the last equation is not satisfied, we cannot write y as a sum of a vector in W1 and a vector in W2.
Therefore, there is no solution to this problem. The vector y cannot be expressed as a sum of a vector in W1 and a vector in W2.

The range of the data 112, 121, 184, 189, 177, 190 is 78. option A
How to find 4th proportional?It follows from the concept of proportions that the ratios can be represented as follows;
21 : 7 = 4 : 3a + 1
21/7 = 4 / (3a + 1)
cross product
21 × (3a + 1) = 4 × 7
63a + 21 = 28
subtract 21 from both sides
63a = 28 - 21
63a = 7
a = 7/63
a = 1/9
So,
3a + 1
= 3(1/9) + 1
= 3/9 + 1
= 1/3 + 1
= 1 ⅓
= 4/3
21 : 7 = 4 : 4/3
Range of the data:

could someone explian to me how to do these two? i’m not sure if i’m doing it right plz help
Step-by-step explanation:
Before I discuss how to graph both equations, I believe that it is essential to understand the variables and constant related to linear equations.
The slope-intercept form is: y = mx + b, where:
m = slope (which tells you the steepness of the line).
b = y-intercept: this is the point on the graph where it crosses the y-axis. Its coordinates is always formatted as, (0, b). The b is the y-coordinate of the y-intercept that you use for the equation.
The standard form of linear equations is: Ax + By = C, where:
A, B, C are integers (whole numbers, and cannot be in fraction or decimal forms). A and B ≠ 0, and A must be a positive integer.
Now that I have defined what the slope-intercept and standard form of linear equations are, we can proceed with working on graphing both equations.
7. y = -6x - 4In this equation, the slope (m) = -6, and the y-intercept (b) = -4. As an ordered pair, the y-intercept is (0, -4). In order to graph this equation, start by plotting the y-intercept on the graph. Then, use the slope (rise over run) to plot other points on the graph (6 units down, 1 unit run). Your next point should occur at (1, -10).
You could simply connect these two points and draw a line, or plot another point on the graph using the slope technique mentioned in this post.
8. 3x - 4y = 12This equation is in standard form, Ax + By = C. It is easier to graph a linear equation when it is in its slope-intercept form, y = mx + b.
In order to transform this equation into its slope-intercept form, start by subtracting 3x from both sides of the equation:
3x - 4y = 12
3x - 3x - 4y = - 3x + 12
-4y = -3x + 12
Next, divide both sides by -4 to isolate y:
\(\frac{-4y}{-4} = \frac{-3x + 12}{-4}\)
y = ¾x - 3 ⇒ This is the slope-intercept form where the slope, m = ¾, and the y-intercept is b = -3.
Similar to how we graphed the equation from question 7, start by plotting the y-intercept, (0, -3). Then, use the slope of the equation, m = ¾ (3 units rise, 4 units run) to plot the next point. The next point should occur at (0, 4).

For this rule, you should repeat the base and multiply the exponents.Exponent negative - For this rule, you should write the reciprocal number with the exponent positive.Zero Exponent. When you have an exponent equal to zero, the result must be 1.For solving this question, you should apply the power rules and check the options are equivalent to the given expression \(6*(36)^{\frac{x}{2}+3}*(2)^{5x}\).
From the power rules, you can simplify the given expression, as shown below.
\(6*(36)^{\frac{x}{2}+3}*(2)^{5x}=6*(6^2)^{\frac{x}{2}+3}*(2)^{5x}\\ \\ 6*(36)^{\frac{x}{2}+3}*(2)^{5x}=6*(6)^{x+6}*(2)^{5x}\\ \\ 6*(36)^{\frac{x}{2}+3}*(2)^{5x}=6*6^x*6^6*(2)^{5x}\\ \\ 6*(36)^{\frac{x}{2}+3}*(2)^{5x}=6^{(x+7)}*(2)^{5x}\)

The term which is used for describing the number of voters who casted their votes using the ballots is called as voter turnout.
The process of selecting a candidate for a suitable post who takes care of the policies which will be framed for the people is called as voting. In this process, the members/ citizens casts their vote in the favor of their suitable candidate. Many times voters are not valid and their votes are considered as null and void.
The voter turnout is either the percentage of registered voters, eligible voters, or all voting-age people ( this varies from place to place depending upon the minimum voting age required). The voter turnout is also referred to the number of people who go to it or take part in it. High voter turnout is generally considered a sign of a healthy democracy.

in rolling a pair of fair dice, what is the probability that a sum of 7 is rolled before a sum of 8 is rolled ?
There are 36 possible outcomes when rolling a pair of fair dice, and each outcome is equally likely. Therefore, the probability of rolling a sum of 7 before a sum of 8 is 1/6.
We want to find the probability of rolling a sum of 7 before a sum of 8.
One way to approach this problem is to use the concept of conditional probability.
Let A be the event that a sum of 7 is rolled before a sum of 8, and let B be the event that a sum of 7 or 8 is rolled on the first roll. Then, we can express the probability of A as:
P(A) = P(A | B) * P(B) + P(A | B^c) * P(B^c)
where B^c is the complement of B (i.e., the event that neither a sum of 7 nor 8 is rolled on the first roll).
Since the sum of 7 and the sum of 8 are the only ways to win the game, P(B) = 6/36 + 5/36 = 11/36. Also, if a sum of 7 or 8 is rolled on the first roll, the game continues with the same rules, but with one fewer roll.
Therefore, we have:
P(A | B) = P(win on next roll) = P(sum of 7) / P(sum of 7 or 8) = 6/11
P(A | B^c) = P(win after next roll)
=P(sum of 7 on second roll) / P(neither sum of 7 nor 8 on first roll)
= (6/36 * 5/30) / (20/36)
= 1/12
Substituting these values into the equation above, we get:
P(A) = (6/11) * (11/36) + (1/12) * (25/36) = 1/6
Therefore, the probability of rolling a sum of 7 before a sum of 8 is 1/6.

Solve. x/4 + ½ = 1/8
x = ____ (Simplify your answer.)
Answer:
\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)
\( \frac{x}{4} = - \frac{3}{8} \)
\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.
Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.
x/4 + 1/2 = 1/8
Take the 1/2 term on the other side,
x/4=1/8 - 1/2
Taking the LCM on the Right side,
x/4 = (1-4) / 8
x/4 = -3/8
Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,
x = ( -3/8) * 4
x = -3/2
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Answers:
tan(A) = 8/15
sin(A) = 8/17
cos(A) = 15/17
==================================================
Explanation:
The tangent ratio involves the opposite over adjacent. With respect to angle A, the opposite side is 8 units long as this side is as far as possible away from angle A. In contrast, the adjacent side is 15 units long because this leg is closest possible and the two are right next to one another.
Therefore,
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 8/15

As for the other trig ratios, they are:
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse

find two incomparable elements in these posets. a) (p({0,1,2}),⊆) b) ({1,2,4,6,8},|)
To find two incomparable elements in a poset, we need to identify two elements that cannot be compared using the partial order relation of the poset.
a) In the poset (P({0,1,2}), ⊆), we are dealing with the power set of {0,1,2} ordered by set inclusion. This means that for any two sets A and B, if A is a subset of B, then A is less than or equal to B in the partial order. To find two incomparable elements, we need to find two sets that are not subsets of each other. For example, {0,1} and {2} are incomparable since neither is a subset of the other. Another example would be {0,1} and {1,2}, since neither is a subset of the other.
b) In the poset ({1,2,4,6,8}, |), we are dealing with the set of positive integers {1,2,4,6,8} ordered by divisibility. This means that for any two integers a and b, if a divides b (i.e. b is a multiple of a), then a is less than or equal to b in the partial order. To find two incomparable elements, we need to find two integers that do not divide each other. For example, 2 and 8 are incomparable since 8 is not divisible by 2, and neither is 2 divisible by 8. Another example would be 4 and 6, since they have no common factors and therefore are not divisible by each other.

f(x) = 2x + 1 where x ∈ N , x < 5
Here x belongs to natural numbers less than 5 which implies x is equal to 1, 2, 3, 4.
Substitute the values of x to get the range (output values ).
f(1) = 2(1) + 1
= 3
f(2) = 2(2) + 1
= 5
f(3) = 2(3) + 1
= 7
f(4) = 2(4) + 1
= 9
Range of f(x) = { 3, 5, 7, 9 }.
Therefore, the range of any function is its output values example
f(x) = 2x + 1 , x ∈ N , x < 5 have range = { 3,5,7,9}.

il change facility follows the uniform probability distribution between 21 and 38 minutes. What is the probability that a randomly selected car will require exactly 30 minutes to service
The probability that a randomly selected car will require exactly 30 minutes to service is approximately 0.0588 or 5.88%.
To find the probability that a randomly selected car will require exactly 30 minutes to service, we need to determine the probability density function (PDF) of the uniform distribution.
In a uniform distribution, the PDF is constant within the given interval and zero outside of it. The interval for this problem is between 21 and 38 minutes.
Since the distribution is uniform, the PDF is given by:
f(x) = 1 / (b - a)
where a is the lower bound of the interval (21 minutes) and b is the upper bound of the interval (38 minutes).
Plugging in the values:
f(x) = 1 / (38 - 21) = 1 / 17
Now, to find the probability that a randomly selected car will require exactly 30 minutes, we need to calculate the area under the PDF curve at x = 30.
The probability is equal to the value of the PDF at x = 30:
P(X = 30) = f(30) = 1 / 17 ≈ 0.0588
Therefore, the probability that a randomly selected car will require exactly 30 minutes to service is approximately 0.0588 or 5.88%.
