To determine if a misspelled name is repeated throughout a dataset, a data analyst can use the COUNT function. This function counts the number of occurrences of a value in a range of cells.
Alternatively, the data analyst could use the COUNTA function, which counts the number of cells in a range that contain data (including text and numbers, but not empty or blank cells). The COUNTA function would also count the number of occurrences of the misspelled name in the dataset.
What is a dataset, using an example?
A collection of numbers or values pertaining to one subject constitutes a data set. An example of a data set might be each student's test scores for a certain class. The amount of fish that each dolphin eats in an aquarium is a data set.

points on a perpendicular bisector of a line segment are equidistant from the segment’s endpoints. is the meaning of _____
Points on a perpendicular bisector of a line segment are equidistant from the segment’s endpoints is the meaning of perpendicular bisector theorem
The perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment ,then it is equidistant from the segment's endpoints.
The perpendicular bisector of a triangle is the line segment that is drawn from a vertex to the opposite side bisecting the side at a right angle. The perpendicular of a triangle is perpendicular to the sides drawn from the opposite vertices and divides the sides into two equal parts. The point at which all the three perpendicular bisectors of a triangle meets is called the circumcenter of a triangle.

The solution of the quadratic equation using the quadratic formula is
x = 4 + 2√6 or 4 - 2√6
How to solve a quadratic equation using quadratic formula?The quadratic formula is a formula used to solve quadratic equations, which are equations of the form ax² + bx + c = 0 where a, b, and c are constants. The quadratic formula is:
x = (-b±√(b²-4ac))/(2a)
Given: x² - 8x - 84 = 0
Here, a = 1, b = -8 and c = -84
x = (-b±√(b²-4ac))/(2a)
x = [-(-8)±√((-8)²-[4×1×(-8)])]/(2a)
x = [8±√(96)]/2
x = (8± 4√6)/2
x = 4 ± 2√6
x = 4 + 2√6 or 4 - 2√6

A cell phone is originally priced at $120. The store owner gives a discount and the cell phone is now priced at $90. Find the percentage discount for the cost of the cell phone,.
Answer:
25%
Step-by-step explanation:
To find the percentage discount for the cost of the cell phone, we need to first find the difference between the original price and the discounted price:
$120 - $90 = $30
Then we need to divide this amount by the original price and multiply by 100% to express the result as a percentage:
($30 / $120) * 100% = 25%
Therefore, the percentage discount for the cost of the cell phone is 25%.

What are linear equations and functions?
What are the different ways of representing a linear function?
How are key features of a linear function identified and interpreted from a graph?
How are key features of a linear function identified and interpreted from a table?
How are key features of a linear function identified and interpreted from an equation?
How are key features of a linear function identified and interpreted from a description?
Step-by-step explanation:
first of all, a function is an equation.
it associates a function result variable (typically called y) with a calculation based on an input variable (usually caked x), or in more complex mathematics based on a group of input variables.
but not every equation is a function. to be a function every valid x value must have exactly one associated y value.
e.g. x = 5 is an equation. but it does not restrict y in any way. so, any value of y (infinitely many) is valid for x = 5.
therefore, this is not a function.
a linear equation/function is a straight line (hence the name).
it is characterized by an inclination (typically called slope or rate of change) and its absolute position typically incentives by the interception points particularly with the y-axis on a coordinate grid.
there are various ways to describe a line in a formal way.
the slope-intercept form :
y = ax + b
a being the slope, b being the y-intercept (y-value when x = 0).
the point-slope form
y - y1 = a(x - x1)
again, a is the slope, (x1, y1) is an identified point (coordinates) on the line.
the general (often called standard) form
gx + hy = c
g, h, c are not describing anything directly, but after transforming this standard form they build the "a" and "b" terms of the other forms.
the slope is the ratio of (y coordinate change / x coordinate change) when going from one point on the line to another. for a line this is constant for any pair of points you can pick on the line.
in other words it tells us how many units y changes, when x changes by a certain amount of units
basically, a line is the collection of all the points for which the given equation is true (when using the x coordinate in the equation we get the corresponding y as calculation result, or when using x and y of any point on the line in the equation, then the equation is true).
graph :
the slope is found by checking 2 points and calculating the y diff / x diff ratio. e.g. starting with (0, 0) if that point is in the line, we increase x by 1 and check the y value there : (1, y).
so, the slope is for that example (y - 0)/(1 - 0) = y.
the y-intercept is found by checking the y-value for x = 0.
the y-interception point is therefore (0, b).
the x-intercept is the x-value when y = 0.
the x-interception point is therefore (x-intercept, 0).
table :
for the slope we pick again 2 data points of the table and calculate y diff / x diff.
as explained this has to be constant for any picked pair of data points of the table. then you know it is a linear equation.
if we are lucky, the table contains data points with x = 0 and/or y = 0. then we have the corresponding intercept values.
but if not, we need to use the coordinates of 1 point in the e.g. slope-intercept form to create an equation with 1 variable : b. and then we solve it to get b.
equation :
we need to bring the equation into a form that we get
y = ...
then the factor of x is the slope. and the constant term (even if it is not there, as it means it is 0) defines the y-intercept
everything else is as described above
description :
the description needs to give us either data points or an indication about the slope and the y-intercept.
when we have 2 points, we can define a line through them. in other words, any pair of points defines a line.

Answer:
(x + 6)^2 + (y - 8)^2 = 81
Step-by-step explanation:
Simplify: -3x + 6 - 3x - 24 + 2y
-6x + 2y - 18
2y - 18
6x + 2y - 30
None of these choices are correct.
Answer:
To simplify the expression -3x + 6 - 3x - 24 + 2y, you can start by combining like terms.
-3x and -3x are both negative, so they can be combined to give -6x.
6 and -24 are both constants, so they can be combined to give -18.
So the simplified expression is: -6x - 18 + 2y
If you want to write the expression in standard form, you can rearrange the terms to give: 2y - 6x - 18
CORRECT ME IF I'M WRONGa party store has 54 packs of plates in stock. the packs are either sets of 8 or sets of 12. if the store has 496 total plates in stock, how many plates would a customer but if he or she buys all of the packs of 12 that the store has in stock?
If the customer purchases every pack of 12 which the shop has 192 plates in stock.
Explain the method of substitution?Three steps make up the substitution technique: For each of the variables, solve one equation. Put this expression (or plug it in) into the other equation, then solve it. To identify the matching variable, rewrite the value's original equation.Total number of packs of plates = 54.
The set are either sets of 8 or sets of 12.
Let x represent the overall number of 12-plate packets.
There will therefore be in total packs of 8 plates: 54 - x.
Thus,
8(54−x) + 12x = 496
432 − 8x + 12x = 496
4x = 64
x = 16
Thus, there are 16 packs of 12 plates in the store.
So, if a consumer purchases all of the 12-packs of plates, he will ultimately purchase 1216 = 192 plates.

If the interest charged on a $50,000, 60-day note payable, at the rate of 6%, would be $500.
In the given question, we have to find the interest charged on a $50,000, 60-day note payable, at the rate of 6%.
The note payable = $50,000
Rate = 6% = 0.06
Period outstanding = 60
The total interest formula is a way to calculate the total simple interest on a sum of money over time at a specific interest rate.
Total Interest charged = Note Payable * rate * period outstanding
Total Interest charged = $50,000 * 0.06 * 60/360
Total Interest charged = $500
Hence, if the interest charged on a $50,000, 60-day note payable, at the rate of 6%, would be $500.
