The table of values
On the table, we have the following ordered pairs
(9, -6) and (11, -12)
The rate of the table is then calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (9, -6) and (11, -12)
Substitute the known values in the above equation
So, we have the following equation
Slope = (-12 + 6)/(11 - 9)

In a circle with radius 8, an angle intercepts an arc of length 16pi/3. Find the angle in radians in simplest form.
The angle in radians in simplest form is 2π/3 radians.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.
Given the radius of the circle = 8
and length of arc = 16π/3
the relation between angle and arc is given by,
s = rθ
where r = radius, s = arc length and θ = angle in radians,
so, θ = s/r
θ = (16π/3)/8
θ = 2π/3 radians
Hence the angle is 2π/3 radians.

For a moving object, the force acting on the object varies directly with the objects acceleration. When a force of 40 N acts on a certain object, the acceleration of the object is 4 m/s^2. If the acceleration of the object becomes 9 m/s^2, what is the score?
Answer:
Step-by-step explanation:
We can use the proportionality relationship between force and acceleration, which is given as:
force = constant × acceleration
Let's call the constant of proportionality k. Then we can write:
40 N = k × 4 m/s^2
Solving for k, we get:
k = 40 N / 4 m/s^2 = 10 Ns^2/m
Now we can use this value of k to find the force required for an acceleration of 9 m/s^2:
force = k × acceleration = 10 Ns^2/m × 9 m/s^2 = 90 N
Therefore, the force required for an acceleration of 9 m/s^2 is 90 N.

3. you want to determine whether the race of the defendant has an impact on jury verdicts. you assign participants to watch a trial with either a hispanic or caucasian defendant, and you measure on a 1 (not at all) to 7 (very) scale how guilty the defendant is. what is the best dv scale of measurement?
The best discrete variable of measurement for the situation is an interval.
What is the Scale of Measurement?Finding the scale of measurement for the variables is the next step in selecting a statistical test after identifying the independent and dependent variables. The dependent variable must be measured using an interval or ratio scale for each of the parametric tests that we have covered so far. Many psychologists also subject variables with roughly interval scales of measurement to parametric tests. You must decide whether to use "scale" or "interval" scores when performing parametric tests of means.
Given the condition about whether the race of the defendant has an impact on jury verdicts,
and measure on a 1 (not at all) to 7 (very) scale how guilty the defendant,
The best scale of measurement for the condition is an interval.
Although the interval scale has characteristics of nominal and ordered data, it also allows for the quantification of data point differences. The variables' actual positions in the order as well as their differences are both displayed by this form of data. They can be combined or split, but not added to or subtracted from.
The fact that zero is an existing variable adds another characteristic to this scale. Zero in the ordinal scale indicates that there is no data.
Hence the scale of measurement is an interval.

many would she make during the season if she had 135 total attempts?
If she makes 135 attempts, the number of throws will be 40.5 .
How to find the number she makes?Number of free throws made by a basketball player varies directly with number of attempts the player has. If she makes 12 out of 40 attempts, the amount of throws she will make during the season if she made 135 total attempts can be calculated as follows:

Are the domain and range of function F? F(x)=x-6\x^2-3x-18
Answer:
domain: all x except -3, 6range: all y except 0, 1/9Step-by-step explanation:
You want the domain and range of the function ...
F(x) = (x -6)/(x² -3x -18)
DomainWe can simplify the function to ...
[tex]F(x) = \dfrac{x-6}{x^2-3x-18}=\dfrac{x-6}{(x-6)(x+3)}\\\\F(x)=\dfrac{1}{x+3}\quad x\notin\{-3,6\}[/tex]
The domain is the set of x-values for which the function is defined. It is undefined where the denominator is zero. So, x=-3 and x=6 are excluded from the domain, which would otherwise be all real numbers.
RangeThe range is the set of values that the function may have. Here, the function can have any y-value except 0 (the value of the horizontal asymptote), and 1/9, the location of the "hole" at x=6.
The range is all real numbers except 0 and 1/9.
A charity needs to report its typical donations received. The following is a list of the donations from one week. A histogram is provided to display the data.

A graph titled Donations to Charity in Dollars. The x-axis is labeled 10 to 19, 20 to 29, 30 to 39, 40 to 49, and 50 to 59. The y-axis is labeled Frequency. There is a shaded bar up to 8 above 10 to 19, up to 6 above 20 to 29, up to 2 above 30 to 39, and up to 2 above 50 to 59. There is no shaded bar above 40 to 49.
Which measure of center should the charity use to accurately represent the data? Explain your answer.
The median of 22.7 is the most accurate to use to show that they have plenty of money.
The mean of 20 is the most accurate to use to show that they need more money.
The median of 20 is the most accurate to use, since the data is skewed.
The mean of 22.7 is the most accurate to use, since the data is skewed.
Answer: C. The most accurate measure of center to represent the data in this case is the median of 20.
Step-by-step explanation: The median is the middle value in a dataset when the data is arranged in ascending or descending order. In this case, the donations are: 10, 10, 10, 10, 15, 15, 15, 19, 20, 20, 20, 25, 25, 25, 30, 30, 55, 55.
When we arrange these values in ascending order, we get: 10, 10, 10, 10, 15, 15, 15, 19, 20, 20, 20, 25, 25, 25, 30, 30, 55, 55.
The median is the value that separates the dataset into two equal halves. In this case, there are 18 values, so the middle value is the 9th value, which is 20.
The reason the median is the most accurate measure of center to use in this case is because the data is skewed. Skewness refers to the asymmetry in the distribution of data. In this case, the data is skewed to the right because there are a few large values (55) that pull the mean higher than the majority of the values.
Using the mean, which is calculated by summing all the values and dividing by the total number of values, would be influenced by these large values and may not accurately represent the typical donations received by the charity.

The Height of the building = 215ft
Consider an object AB of height h such that its shadow of length s is formed and angle of elevation is θ.
The object AB depicts a right triangle in which ∠ABO = 90o.
Now we know that in trigonometry, the tangent ratio for an angle is equal to the opposite side to that angle divided by its adjacent side.
So, for the angle of elevation θ, we have
=> tan θ = AB/OB
Putting AB = h and OB = s, we get

The mean daily pocket money of 35 pupils in another class is m cents. Given that the mean daily pocket money of the 80 pupils from these two classes is 72.25 cents, calculate the value of m.
Answer:-0.696
Step-by-step explanation:Let the total daily pocket money of the 35 pupils in the other class "A" and the total daily pocket money of all 80 pupils "B".
The mean daily pocket money of the 35 pupils in the other class is m cents, so:
A = 35 * m
The mean daily pocket money of all 80 pupils is 72.25 cents, so:
B = 80 * 72.25
Since we know the total pocket money of both classes, we can use this information to solve for m:
A + B = 115 * m
35 * m + 80 * 72.25 = 115 * m
35 * m = 115 * m - 80 * 72.25
35 * m = 115 * m - 5780
5780 = 115 * m - 35 * m
5780=80 * m
Finally, we can solve for m:
m = 5780/80
m = 72.25
Is 20 - 5x = 50- 10x true ?
Answer:
Step-by-step explanation:
that is incorrect.
if it were to be equal, one side should equal each other when multiplied to make the ratio equal.
20-5x=40-10x (when multiplied by 2 on each side)
It CANNOT equal 50, if it were there would not be -10x
20-5x=100-25x
DIVIDE BY 2 to get 50 WOULD GIVE:
20-5x=50-17.5x
Answer:
Yes
Step-by-step explanation:
solve the equation for x , then evaluate and compare both sides
20 - 5x = 50 - 10x ( add 10x to both sides )
20 + 5x = 50 ( subtract 20 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
then
left side = 20 - 5x = 20 - 5(6) = 20 - 30 = - 10
right side = 50 - 10x = 50 - 10(6) = 50 - 60 = - 10
since both sides are equal then
20 - 5x = 50 - 10x is true

To find 4f(-2) + 5f(1), we need to first find the values of f(-2) and f(1). Using the given equation, we have:
An easy definition of a function
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
f(-2) = -(-2) - 11 = 9
f(1) = -1 - 11 = -12
So, 4f(-2) + 5f(1) = 4 * 9 + 5 * -12 = 36 - 60 = -24.
To find 3f(5) * 2, we need to first find the value of f(5). Using the given equation, we have:

f(12) = -12 - 11 = -23
f(-9) = -(-9) - 11 = 2
So, -5f(12) - 2f(-9) = -5 * -23 - 2 * 2 = 115 + 4 = 119
To find f(9)/f(-6), we need to first find the values of f(9) and f(-6). Using the given equation, we have:
f(9) = -9 - 11 = -20
f(-6) = -(-6) - 11 = 5
So, f(9)/f(-6) = -20 / 5 = -4.

General Sherman, a tree located in Sequoia National Park, stands 275
feet tall. To see the top of the tree, Carlos looks up at a 15° angle of elevation. If Carlos is 6 feet tall, how far is he from the base of the tree to the nearest foot? There are 4 options A.1004 B.1020 C.1026 D.1049
Answer:
Step-by-step explanation:
If Carlos is 6ft tall and looks up at the tree that is 275 ft tall, subtract those two.
275 - 6 = 269
Use tangent with the given angle and the new height. The distance is x.
tan15 = 269/x
x = 269/tan15
x = 1004ft
The distance from Carlos to the tree, given he is 6 feet tall and looks up at a 15° angle of elevation to see the top of a 275-foot tall tree located in Sequoia National Park, is 1026.
Hence option C is correct.
According to the information given,
We can set up a right triangle with Carlos's eye level, the top of the tree, And the base of the tree as the three points of the triangle.
Carlos's height of 6 feet can be used as one side of the triangle,
And we can use the tangent function to find the length of the adjacent side.
A tangent of 15 degrees is equal to the opposite side (height of the tree) divided by the adjacent side (distance from Carlos to the tree).
So, we can solve for the adjacent side by multiplying the height of the tree by the tangent of 15 degrees:
tan(15) = height of the tree / distance from Carlos to the tree
Distance from Carlos to the tree = height of the tree / tan(15)
Plugging in the values given:
Distance from Carlos to the tree = 275 / tan(15)
≈ 1026
Therefore,
The nearest foot to the distance from Carlos to the tree is option C. 1026.
