What is a outlier in math example?
In a dataset or graph, outliers are extreme values that greatly deviate from the dominant pattern of values.
How do you find the outlier in math?In order to identify the outlier, search for a value that is significantly greater or smaller than all the other values. Due to its extreme size compared to all other numbers, the number 267 is an outlier.
a value that "lies outside" (i.e., is significantly smaller or substantially bigger) most of the other values in a set of data For instance, both 3 and 85 in the scores 25, 29, 3, 32, 85, 33, 27 and 28 are "outliers".
A data point that is an outlier in a data graph or dataset you are dealing with is one that is extraordinarily high or extraordinarily low in comparison to the nearest data point and the rest of the nearby coexisting values. Outliers in a dataset or graph are extreme values that stand out significantly from the main pattern of values.

At the grocery Store, 2 bags of chips cost 6$ how many would be 24$
Answer:
8 bags of chips.
Step-by-step explanation:
First, find the cost per individual unit. It is given that 2 bags of chips cost $6. Find the cost of one bag by dividing 6 with 2:
$6/2 bags = $3/bag
Next, you are solving for the amount of chips you can buy with $24. Divide 24 with the individual cost of $3:
$24/$3 per bag = 8
You can buy 8 bags of chips assuming all things are the same.

The possible outcomes of a random experiment are the different outcomes that can occur when you perform an experiment.
The probability of each outcome is the chance of that outcome occurring.
A probability distribution is a table that shows the relative frequencies or chances of different outcomes occurring in a random experiment. The example below shows a probability distribution for flipping a coin:
In a random experiment, the possible outcomes are called outcomes. There are three types of outcomes: successes, failures, and ties. A success is when an event happens exactly as planned for it to happen. A failure is when an event doesn't happen at all or doesn't happen in the way that was expected.

The coordinates of the point on the unit circle corresponding to a central angle of 21 degrees are (0.93, 0.36), which is answer choice c.
The point on the unit circle corresponding to a central angle of 21 degrees can be found using the trigonometric functions sine and cosine.
In this case, the x-coordinate is equal to the cosine of the angle and the y-coordinate is equal to the sine of the angle.
Converting degrees to radians, we have:
x = cos(21) = 0.93
y = sin(21) = 0.36

The Total number of cherries on a plate, in a cup, and in a bowl is 780. The plate contains 145 cherries. The number of cherries in the bowl is 4 times the total number of cherries on the plate and in the cup. How many cherries are in the cup?
Using Mathematical Expressions, Let's call the number of cherries in the cup "x". There are 11 cherries in the cup.
A mathematical expression is what?A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations. This mathematical operation enables the multiplication, division, addition, or subtraction of numbers. The following is the structure of an expression: Expression: (Number/Variable, Math Operator, Math Operator)
We know that:
Total number of cherries = 780
Number of cherries on the plate = 145
Number of cherries in the bowl = 4 * (Number of cherries in the cup + Number of cherries on the plate)
So we can set up the equation:
x + 145 + 4(x + 145) = 780
Simplifying, we can combine like terms:
x + 145 + 4x + 580 = 780
5x + 725 = 780
Subtracting 725 from both sides:
5x = 55
Finally, we can divide both sides by 5:
x = 11
So there are 11 cherries in the cup.

for what values of t and s does the equality ⟨−(7t 2),3s−2t⟩=⟨3s−t,2 4t⟩
The values of t and s that satisfy the equality are t = sqrt(3 * 74.67 / 49) and s = sqrt(3 * 74.67 / 49).
The equality ⟨−(7t^2), 3s-2t⟩ = ⟨3s-t,24t⟩ means that the two vectors are equal, so the components must be equal:
-7t^2 = 3s-t
3s-2t = 24t
Solving for t, we can subtract 24t from both sides:
3s-26t = 0
Dividing both sides by 3, we get:
s - 8.67t = 0
So, t = s / 8.67.
Substituting t = s / 8.67 back into the first equation, we get:
-7(s / 8.67)^2 = 3s - s / 8.67
Expanding and simplifying, we get:
-49s^2 / 74.67 + 3s = s^2 / 74.67
Dividing both sides by s^2 / 74.67, we get:
-49 + 3 * 74.67 / s = 1
Multiplying both sides by s^2 / 74.67, we get:
-49s^2 + 3 * 74.67 = s^2
Expanding and rearranging, we get:
s^2 - 49s^2 + 3 * 74.67 = 0
Combining like terms, we get: -49s^2 + 3 * 74.67 = 0
Dividing both sides by -49, we get: s^2 = 3 * 74.67 / 49
Taking the square root of both sides, we get: s = sqrt(3 * 74.67 / 49)
Thus, the values of t and s that satisfy the equality are t = sqrt(3 * 74.67 / 49) and s = sqrt(3 * 74.67 / 49).

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3) crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, negative 3). Which statement is true about the graphed function? Group of answer choices F(x) < 0 over the interval (–∞, –4) F(x) < 0 over the interval (–∞, –3) F(x) > 0 over the interval (–∞, –3) F(x) > 0 over the interval (–∞, –4)
f(x) > 0 over the interval ( - ∞ , - 4 )
What is the short definition of a coordinate plane?
A surface with two dimensions known as the coordinate plane is created by two number lines. The x-axis is a single number line that runs horizontally.
The y-axis is the name given to the vertical number line that is the other number line. A place known as the origin is where the two axes collide. To graph points, lines, and other things, we can utilize the coordinate plane.
If f(x) is a continuous function, and that all the critical points of behavior change are described by the given information, then we can say that the function crossed the x axis to reach a minimum value of -12 at the point x=-2.5, then as x increases it ascends to a maximum value of -3 for x = 0 (which is also its y-axis crossing) and therefore probably a local maximum.
Then the function was above the x axis (larger than zero) from -∞ , until it crossed the x axis (becoming then negative) at the point x = -4. So the function was positive (larger than zero) in such interval.
There is no such type of unique assertion regarding the positive or negative value of the function when one extends the interval from -∞ to -3, since between the values -4 and -3 the function adopts negative values.

a) The van der Waals equation for n moles of a gas is(P+ n'a v2)(V — nb) = nRT -where p is pressure, V is Volume, and T is the temperature of gas. The constant R is the universal gas constant and a and b are positive constants that are characteristics of a particular gas. If T remains constant, use implicit differentiation to find dV/dP.b) Find the rate of change of volume with respect to pressure of 1 mole of carbon dioxide at a volume of V= 10 L and a pressure of P=2.5atm. Use a=3.592 L2-atm/mole² and b=0.04267 L/mole.
For every additional atmosphere of pressure applied to 1 mole of carbon dioxide at a volume of 10 L, the volume will decrease by 9.5633 L.
The van der Waals equation is an important tool for understanding the behavior of gases. It is a mathematical equation that relates the pressure, volume, and temperature of a gas.
To find the rate of change of volume with respect to pressure, we use implicit differentiation.
This means that we take the derivative of both sides of the equation with respect to pressure (dP) while keeping all other variables constant.
After some algebraic manipulation, we find that
=> dV/dP = (V - nb)/(P + n'aV2).
This result tells us how the volume of a gas changes as the pressure changes.
To calculate the rate of change of volume with respect to pressure for 1 mole of carbon dioxide, we use the values of
V= 10 L, P=2.5atm, a=3.592 L2-atm/mole², and b=0.04267 L/mole.
Plugging in these values, we find that
=> dV/dP = (10 L - 0.04267 L)/(2.5atm + 3.592 L2-atm/mole² x 10 L2)
=> 9.5633 L/atm.
