Answer:
C
Step-by-step explanation:
Since the graph hits 0 at x = 0, your y intercept is 0.
The graph is decreasing which means you have a negative slope.
They gave you a coordinate so use it to find the slope.
\(\frac{1-0}{-3-0} = \frac{-1}{3}\)
That's your slope.
C is the correct answer.

during his nba career, larry bird made approximately 89% of all free throws. suppose larry makes 10 free throws in a row. what is the probability he will make the next free throw?
Probability that he will make the next free throw is 0.89% if larry bird made approximately 89% of all free throws during his nba career.
During nba career he made approximate 89% of all free throws.
To calculate the probability of the next 10 free throws given which will be
= No. of possible outcome / Total no. of outcome
= 89 / 100
= 0.89 %
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcome like how likely they are.
P(A) = (# of ways A can happen) / (Total number of outcomes)

Let X1, X2 ..., Xn be a random sample of size n from a geometric distribution for which p is the probability of success. Use the method of moments to find a point estimate for p. Explain intuitively why your estimate makes good sense. Use the following data to give a point estimate of p: 3 34 7 4 19 2 1 19 43 2 22 4 19 11 7 1 2 21 15 16
This involves setting the sample mean equal to the theoretical mean and solving for p. Using the given data, we obtain a point estimate of p = 0.101.
The geometric distribution is commonly used to model the number of independent trials needed to obtain the first success in a sequence of Bernoulli trials with probability of success p. The theoretical mean of a geometric distribution is μ = 1/p, which represents the expected number of trials needed to obtain the first success.
To find a point estimate for p using the method of moments, we first calculate the sample mean of the given data, which is X' = 13.8. We then set this equal to the theoretical mean and solve for p:
X' = 1/p
13.8 = 1/p
p = 1/13.8
p ≈ 0.101
Intuitively, this estimate makes sense because it represents the proportion of successes expected in a single trial, based on the given sample. In other words, if we were to repeat the same sequence of trials many times, we would expect to see a success rate of approximately 0.101.
Additionally, since the geometric distribution is memoryless, meaning the probability of success does not depend on the number of previous trials, this estimate can be used to make predictions about future trials as well.

its a mutilpy choice question the choices are addition, multiplication, and subtraction
Answer:
Step-by-step explanation:
Use PEMDAS to determine order of operations.
P = Parentheses
E = Exponents
M/D = Multiplication/Division
A/S = Addition/Subtraction
The operation in the parentheses must be performed first, which is the addition of 6.1 + 12.
The next operation to perform is multiplication, which is 415 times (6.1 + 12).
The last operation to perform is the subtraction of 415 times (6.1 + 12) from 8.3.
6.1 + 12 = 18.1
8.3 - 415(18.1)
8.3 - 7511.5 = -7503.2
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
Answer:
m [ slope ] = 8/3
Step-by-step explanation:
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
m = ∆y / ∆x
m = y₂ – y₁ / x₂ – x₁
| (5, 1) → (x₁, y₁) | (2, -7) → (x₂, y₂) |
[each coordinate will correspond (directly go to) to the variables shown]
m = (-7) – (1) / (2) – (5)
m = -8 / -3
m = 8 / 3
This means that this line has a rise of 8 and a run of 3.
Up 8 and right 3 proportionally, it would touch the opposite corners of a plane that was 8 by 3 units.
Slope can be thought of as the steepness of a line, the greater the slope, the greater the steepness.
These points are generally known as cartesian coordinates.
____________
Once you have the slope, you can back track from one of the coordinates to find the equation of the line.
Just multiply the slope by the x of either coordinate, make it opposite, and then add that to the y of that coordinate to get b [the y-intercept; where it crosses the y axis, x is always 0]
Since (2, -7) is closer to the y axis than (5, 1) it is more convenient.
In (2, -7), 2 is the x variable and -7 is the y variable.
-mx + y = (-8/3)(2) + (-7) = -16/3 + (-21/3)
21/3 is the same as 7 [so it will have a common denominator].
-16 + -21 / 3 = -37/3 = b
Thus this line has an equation of
y = mx + b
↓ ↓
y = 8/3x – 37/3.
__________________________
Or you can refer to point slope which is what is taught:
y – y₁ = m(x – x₁).
You can tell that there are some similarities to this and the slope formula.
m = ( y₂ – y₁ / x₂ – x₁ ) →
m × ( x₂ – x₁ ) =
( y₂ – y₁ / x₂ – x₁ ) × ( x₂ – x₁ )
[multiply the denominator by both sides]
m ( x₂ – x₁ ) = y₂ – y₁
[x₂, and y₂ can just be x and y since you only need the initial coordinate and slope, because the second coordinate can be anything along that line]
m ( x – x₁ ) = y – y₁ →
y – y₁ = m(x – x₁)
[symmetric property of equality]

true or false: if you are given a graph with two shiftable lines, the correct answer will always require you to move both lines.
False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.
In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.
When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.
In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.
However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.
Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.

Step-by-step explanation:
We can find the other point using the axis of symmetry.
The axis of symmetry for a parabola passes through the x coordinate of the vertex.
So our axis of symmetry is x=4, which is a vertical line.
For any point on a parabola curve except the vertex, there will two points that share the same y value. The two x coordinates of those points midpoints should be the axis of symmetry.
So,
If we know (0,-6) and the vertex is 4, let's find the other point
\(( \frac{0 + b}{2} = 4\)
\(b = 8\)
So our other point is
(8,-6).
So the answer to #1 is we found point (8,-6) by using the axis of symmetry. By reflecting the point (0,-6) about the vertical line x=4, we end up getting the point (8,-6)
To find q, q(x) has the same vertex, so it is (4,10).
We know the axis of symmetry is x=4, we also know the y intercept is 18 so we have point (0,18)
Using the axis of symmetry we will get (8,18).
So the graphs above are the graphs of p and q
The graph facing upwards is q
The graph facing downwards is p.
For #2, you can say we know the vertex is (4,10) and using the y intercept and axis of symmetry we found the other point on the curve.
I don't fully see the table but if the other coordinates have a higher y value, the vertex is a minimum.
Else, of the other coordinates have a lower y value, the vertex is a maximum.

Write an algebraic expression for the sum of the measures of the angles for a polygon with n sides.
The algebraic expression for the sum of the measures of the angles for a polygon with n sides is given by (n-2) * 180 degrees.
In a polygon, the sum of the measures of the interior angles is determined by the number of sides it has. It is known that the sum of the measures of the angles in a triangle is 180 degrees.
For each additional side added to the polygon, an extra triangle is formed, and therefore, an additional 180 degrees is added to the total sum of the angles.
To express this algebraically, we start with the base case of a triangle (n=3), where the sum of the measures of the angles is (3-2) * 180 = 180 degrees. From here, we can observe that for each additional side (n-2), we multiply by 180 to find the total sum of the angles for the polygon.
Thus, the algebraic expression for the sum of the measures of the angles for a polygon with n sides is (n-2) * 180 degrees.

The formula for the positive value of b in terms of a and c is:
b = √(c^2 - a^2)
The Pythagorean Theorem is given by the formula a^2 + b^2 = c^2. It relates the three sides of a right triangle. To solve the formula for the positive value of b in terms of a and c, we will first need to isolate b by itself on one side of the equation:
Begin by subtracting a^2 from both sides of the equation:
a^2 + b^2 = c^2
b^2 = c^2 - a^2
Then, take the square root of both sides to get rid of the exponent on b:
b^2 = c^2 - a^2
b = ±√(c^2 - a^2)
However, we want to solve for the positive value of b, so we can disregard the negative solution and get: b = √(c^2 - a^2)
Therefore, the formula for the positive value of b in terms of a and c is b = √(c^2 - a^2)

if one flag pole is y feet tall and casts a shadow x feet long, then how tall is another nearby flag pole that casts a shadow p feet long at the same time of day?
If one flag pole is y feet tall and casts a shadow x feet long, and another nearby flag pole casts a shadow p feet long at the same time of day, we can use similar triangles to determine the shadow of the second flag pole.
In this scenario, the two flag poles and the ground form two similar right triangles. The height of the first flag pole (y) corresponds to one leg of the first triangle, and the length of its shadow (x) corresponds to the other leg.
Similarly, the height of the second flag pole (h) corresponds to one leg of the second triangle, and the length of its shadow (p) corresponds to the other leg.
Therefore, the height of the second flag pole is equal to the product of the height of the first flag pole and the length of the shadow of the second flag pole, divided by the length of the shadow of the first flag pole.

The statements "A has a pivot position in every row" and "the columns of A span R5" are logically equivalent. C. The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. D. The columns of a 5x7 matrix cannot span R5 because having more columns than rows makes the columns of the matrix dependent.
The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.
A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.
The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.
