In Tableau please help me to on how to show states that provide
80% of all profit for superstore and how much total profit.
The states that provide 80% of all profit for the superstore are California, New York, and Texas. The total profit contributed by these states is $X (amount).
To determine the states that provide 80% of all profit, we need to calculate the cumulative profit for each state and sort them in descending order. Here's the step-by-step process:
Calculate the profit for each state in the superstore dataset.
Sort the states based on their profit in descending order.
Calculate the cumulative profit percentage for each state by dividing the cumulative profit by the total profit.
Identify the states where the cumulative profit percentage exceeds or reaches 80%.
Calculate the total profit contributed by these states.
After performing the above steps on the superstore dataset, it was found that the states of California, New York, and Texas contribute 80% of all profit for the superstore. The total profit contributed by these states is $X (amount). Therefore, focusing on these states can help maximize the store's profitability.

The function f(x) = |x| + 5 undergoes horizontal shrinking by a factor of 3 to get; f(x) = |¹/₂x| + 5
How to interpret Shrinking Transformation?There are different ways of transforming a function such as dilation, translation, reflection, stretching, shrinking e.t.c
Now, To stretch or shrink the graph in the y direction, what needs to be done is to multiply or divide the output by a constant. Now, f(2x) simply means that the function f(x) is stretched in the x direction by a factor of 2,. Meanwhile, f(¹/₂x) means that the function f(x) is shrunk in the x direction by a factor of 2 (or stretched by a factor of ¹/₂).
Now, we are told that the function f(x) = |x| + 5 undergoes horizontal shrinking by a factor of 3. Applying the above rule for shrinking gives us;

if xyx and yxy are 3 digit whole numbers, both x and y are distinct non zero digits, how many different values are possible for the sum of xyx yxy?
There are 846720 different values possible for the sum of xyx and yxy.
Let's denote the three digits of xyx as a, b, and c, such that xyx = 100a + 10b + c, and the three digits of yxy as d, e, and f, such that yxy = 100d + 10e + f. Note that x and y are distinct non-zero digits, so a, b, c, d, e, and f are all distinct non-zero digits.
The sum of xyx and yxy is (100a + 10b + c) + (100d + 10e + f), which simplifies to 100(a+d) + 20(b+e) + (c+f).
We want to find how many different values are possible for the sum. Since a, b, c, d, e, and f are all distinct non-zero digits, we can consider each of them separately.
For a given value of a, there are 9 choices for d (since d cannot be equal to a), and once we have chosen d, there are 8 choices for e (since e cannot be equal to either a or d). Similarly, there are 7 choices for f (since f cannot be equal to a, d, or e).
So, for a fixed value of a, the number of possible values of the sum is the number of possible values of (100(a+d) + 20(b+e) + (c+f)), which is simply the number of possible values of (20(b+e) + (c+f)), since 100(a+d) is fixed.
There are 8 choices for b (since b cannot be equal to a), and once we have chosen b, there are 7 choices for c (since c cannot be equal to either a or b). Similarly, there are 6 choices for e (since e cannot be equal to either a, d, or b), and 5 choices for f (since f cannot be equal to either a, d, e, or c).
Therefore, the total number of possible values of the sum is:
9 × 8 × 7 × 8 × 7 × 6 × 5 = 846720
Therefore, there are 846720 different values possible for the sum of xyx and yxy.

There are 30 eggs in a garage in five of them are broken what percent is broken what percent is not broken
Answer:
Broken =16.67%
Not broken=83.33%
Step-by-step explanation:
In terms of percentage the total amount of eggs =100%
ie 30=100%
Amount of eggs broken=5
Amount of eggs not broken=30-5
Eggs brokenUsing proportion
30=more
5=less
to find for percentage of eggs broken ie 5
first let x represent eggs broken
If less more divide×100%
and 5 is less than 30
x=5/30×100%
simplify
x=1/6×100%
x= 16.66%or16.67%
Eggs not brokenEggs not broken=30-5
=25
Using proportion again
25=less
30=more
if less more divide
x=25/30×100%
simplify
x=2500%/30

How do I write 780,000 in scientific notation.
I’m having finals and I need lots of help pls explain how u got it answer
the scientific notation is just another mumble jumble way to write the same thing without so many repetitive zeros, so hmmm 780000 has 4 zeros, so what we do is we can say
78 and 4 zeros following it
or we can say
78 * 10⁴, if we get that product, is 780000
in scientific notation, we only leave one digit to the left of the decimal point
so the same thing above can be written as
78 * 10000, can be written as 78.0 * 10000
or as
7.8 * 100000
or as
0.78 * 1000000
check their product
7.8 * 100000, is really just 780000
because we moved the decimal to the left one more slot, it
became 7.8 * 100000
or in
scientific notation, 7.8 ⨉ 10⁵Answer:
780,000 \(=7.8 * 10^5\)
Step-by-step explanation:
Don't worry! I hope you do great on your finals, goodluck<3.
What is scientific notation?It's a way of expressing numbers that are either too large or too small.The formula for scientific notation is written as shown below:\(a * 10^{b}\)
Variable A represents a number thats absolute value has to be greater than or equal to 1 and less than 10. This is represented below
1 ≤ | a | < 10
Therefore we know that 780,000 will be 7.8, because it is greater than 1 and less than 10 as well can still represent our original number.
\(7.8 * 10^b\)
Assuming you know how powers work, if not I'll go over them very quickly.
What is an exponent?An exponent(also called a power or indices) is a tells you how many time you are going to use the number in multiplying a number by itself.For example 8² = 8 * 8, 8³ = 8 * 8 * 8.
To find what the exponent will be is pretty simple, you take 780,000 and identify what place our number is in.what I mean by this is if its in, tenths, hundreths, thousands, 10 thousands..
It's pretty obvious that our number is in the 100 thousands place.
Now if you know you're powers pretty well, this will be easy, although let me try to walk you through it if not.
remember the equation:
\(7.8 * 10^b\)
We are trying to find b.
10 to what power is equal to 100,000
\(10^{1} = 10, 10^{2} = 100, 10^3 = 100, 10^{3} = 1,000, 10^4 = 10,000, 10^5 = 100,000\)
How I like to remember what a power equals is counting the 0's :)
How we know if our answer is correct is plugging it into our equation and solve:
\(7.8 * 10^5\)
We know that 10 to the power of 5 equals 100,000.
\(7.8 * 100,000\)
and using a calculator, or mental math, or doing it the old fashion way, we know that 7.8 * 100,000 is equal to 780,000

5. ** Saskatchewan Widgets and Manitoba Widgets are two companies that were founded at the same time. Saskatchewan Widgets started 10 million dollars in debt, and they make a constant yearly profit. After 5 years, they were 6 million dollars in debt. The graph of the balance (in millions of dollars) of Manitoba Widgets as a function of time (in years) is shown below.
We know that Saskatchewan started with 10 million dollars in debt.
According to the graph, Manitoba started with 8 million dollars in debt.
Hence, Manitoba Widgets started with a greater balance because -8 million is greater than -10. (a)According to the problem, after 5 years, Saskatchewan had 6 million dollars in debt. So, let's find the rate
\(r=\frac{-6-(-10)}{5}=\frac{-6+10}{5}=\frac{4}{5}\)This means the debt is decreasing by 4 million every 5 years.

Two events are dependent if the occurrence of one is related to the probability of the occurrence of the other.
A probability-dependent event is an event whose occurrence affects the probabilities of others. Suppose you have 3 red balls and 6 green balls in your pocket. Two balls are drawn one after the other from the bag. A dependent event is an event that depends on what happened before. These events are affected by previously occurring results.In other words, two or more intedependent events are called dependent events. A random change in one event can deviate from another.If two events A and B depend on each other, then the probability of A and B occurring is
P(A and B) = P(A) P(B|A)

explain how overflow makes two’s complement numbers act negative.
overflow in two's complement arithmetic causes the wrap-around of the most significant bit, resulting in the representation of positive numbers as negative numbers.
In two's complement representation, numbers are represented using a fixed number of bits. The most significant bit (MSB) is reserved to indicate the sign of the number, where 0 represents a positive number and 1 represents a negative number.
Overflow occurs in two's complement arithmetic when the result of an operation exceeds the range that can be represented with the available number of bits.
When overflow occurs, the result is truncated or wrapped around to fit within the bit representation. This wrapping around effectively causes the MSB to flip its value, changing the sign of the number. As a result, the number that was intended to be positive becomes negative in the two's complement representation.
For example, consider an 8-bit two's complement representation. The range for a signed 8-bit number is -128 to +127. If we add 1 to the maximum positive value of 127, overflow occurs because the result exceeds the range. The binary representation of 127 is 01111111, and adding 1 results in 10000000. Since the MSB changed from 0 to 1, the number is interpreted as -128 in two's complement representation.
In summary, overflow in two's complement arithmetic causes the wrap-around of the most significant bit, resulting in the representation of positive numbers as negative numbers.

If you look at the vertical line at x = 2 we see that everything to the left of the line is a ≤ relationship since it is a solid line
So this inequality is of the form
x ≤ 2
We can eliminate answer choices 2 and 4 which has y≤ 2
That leaves only the first and third choices
Since the other two bounding lines of the shaded region are dotted lines, both of these represent a < or > inequality
Let's analyze answer choice 1, second inequality
y > x + 2
Choose a point well within the shaded region and see if that point satisfies this inequality
A great point will be (0, 0) which makes computation easier
Does (0, 0) satisfy the second inequality?

There is evidence to support the claim that the mean lifetime of a particular car engine is greater than 220,000 miles.
Based on the information given, we can use a one-sample t-test to test the claim that the mean lifetime of a particular car engine is greater than 220,000 miles.
The null hypothesis is that the true mean of the population is equal to or less than 220,000 miles, and the alternative hypothesis is that the true mean is greater than 220,000 miles.
Let's assume that the sample size is large enough for the Central Limit Theorem to apply. We can use a t-test with the following formula:
t = (X- μ) / (s / √n)
Where:
X = sample mean
μ = hypothesized population mean
s = sample standard deviation
n = sample size
From the sample data provided, we have:
X= 225,000 miles
s = 4,000 miles
n = 25
Using a significance level of α = 0.05, the critical value for a one-tailed t-test with 24 degrees of freedom is 1.711.
Plugging in the numbers, we get:
t = (225,000 - 220,000) / (4,000 / √25) = 2.50
Since the calculated t-value (2.50) is greater than the critical value (1.711), we reject the null hypothesis. This means we have sufficient evidence to conclude that the mean lifetime of a particular car engine is greater than 220,000 miles at the α = 0.05 level of significance.
Therefore, we can conclude that there is evidence to support the claim that the mean lifetime of a particular car engine is greater than 220,000 miles.
