The standard deviation is the best measurement of spread for games and movies.
To determine the spread of data, various measures can be used. These measures are referred to as measures of spread, dispersion, or variability.
The two most widely used measures of spread are the interquartile range (IQR) and standard deviation (SD).The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
That is, IQR = Q3 - Q1. The IQR gives the range of the middle 50% of data points.
The main advantage of using IQR is that it is not affected by outliers. Outliers are extreme values that lie far away from the bulk of the data points. IQR is more robust than SD when it comes to outliers.
However, IQR ignores the values in the top and bottom 25% of data, which may not give a complete picture of the spread of the data.SD is calculated by first finding the mean of the data and then finding the deviation of each data point from the mean.
The deviations are then squared, summed, and divided by the total number of data points minus one.
The square root of this value gives the SD. SD measures the average ditance of data points from the mean. Unlike IQR, SD takes into account all the data points.
The advantage of using SD is that it gives a complete picture of the spread of the data. SD is also more sensitive to small changes in data than IQR.
Based on the above explanations, it is clear that the standard deviation is the best measurement of spread for games and movies.

Four candidates participated in a school election. Bianca received 1/2 of the votes, Chelsea received 0.28 of the votes, Darnell received 20% of the votes, and Francisco received the rest of the votes. What percent of the votes did Francisco receive?
The percentage of the votes did Francisco receive is = 2%
Given that:
Four candidates participated in a school election.
Bianca received 1/2 of the votes
Chelsea received 0.28 of the votes
Darnell received 20% of the votes
Francisco received the rest of the votes.
Solution:
We know that the sum of all the votes received by the candidates is 100%.
Bianca received 1/2 of the votes
Chelsea received 0.28 of the votes
Darnell received 20% of the votes
Francisco received the rest of the votes.
Therefore, the sum of the votes received by Bianca, Chelsea, Darnell, and Francisco is:
Bianca + Chelsea + Darnell + Francisco = 1/2 + 0.28 + 20% + Francisco%
We know that the sum of all the votes received by the candidates is 100%.
Bianca + Chelsea + Darnell + Francisco = 100%
Converting Bianca's fraction to percent, we get:
Bianca = 1/2 × 100%
Bianca = 50%
Now substituting the values in the expression we get:
50% + 28% + 20% + Francisco% = 100%
Simplify the expression by adding 50%, 28% and 20%
50% + 48% + Francisco% = 100%
98% + Francisco% = 100%
Now we can solve for Francisco by subtracting 98% from each side.
100% - 98% = Francisco%
2% = Francisco%
Hence, Francisco received 2% of the votes.

slove the linear equation x+4+3x=72.state the property that justiflies your first step and why you chose it
\
The solution to the equation is x = 9.71 (rounded to two decimal places). To solve the equation x + 4 + 3x = 72, we will combine like terms and then isolate the variable x.
To solve the linear equation x + 4 + 3x = 72, we'll combine like terms on the left side of the equation. The property that justifies this step is the distributive property. We distribute the coefficient 3 to both x terms, which results in 4x + 3x = 7x.
So, rewriting the equation with the combined like terms, we have 4x + 3x + 4 = 72.
The reason we chose to apply the distributive property is to simplify the equation by adding the coefficients of the x terms together. This allows us to work with a simpler equation and proceed with solving for x.

The approximate probability that a student chooses a computer elective and an art elective is 1 or 100%.
To determine the approximate probability that a student chooses a computer elective and an art elective, we need to consider the total number of electives available and the specific choices a student can make.
To calculate the probability, we can follow these steps:
Determine the total number of possible elective combinations: Since each student can choose two electives, we multiply the number of options for each elective category. In this case, it would be 3 art electives * 5 computer electives = 15 possible combinations.
Determine the number of favorable outcomes: We want to find the number of combinations where a student chooses one art elective and one computer elective. Since there are 3 art electives and 5 computer electives, the number of favorable outcomes is 3 art electives * 5 computer electives = 15 combinations.
Calculate the probability: To find the approximate probability, we divide the number of favorable outcomes by the total number of possible combinations. Therefore, the probability is 15/15 = 1. Therefore, the approximate probability that a student chooses a computer elective and an art elective is 1 or 100%.

The sequence of steps that an accountant generally follows to prepare a bank reconciliation statement is as follows:
Compare the bank statement and the checkbook records to look for differences.
Look for outstanding checks paid by the company but not yet paid by the bank.
Look for debit and credit memoranda and make adjustments in the checkbook balance.
Look for deposits to account for any deposit.
The first step in preparing a bank reconciliation statement is to compare the bank statement and the checkbook records. This involves carefully reviewing the transactions on both documents and identifying any discrepancies or differences between them. These differences can include items such as missing transactions, errors in recording, or timing differences.
Next, the accountant looks for outstanding checks that have been paid by the company but have not yet been paid by the bank. These checks have been deducted from the checkbook balance but may not have cleared the bank yet. Adjustments need to be made to account for these outstanding checks and reconcile the balances.
The accountant then looks for debit and credit memoranda, which are additional transactions recorded by the bank, such as service charges or interest earned. These items are considered in the bank reconciliation process and may require adjustments in the checkbook balance.
Lastly, the accountant examines the deposits made to the bank account to ensure that all deposits have been recorded in the checkbook. Any deposits that have not been accounted for need to be added to the checkbook balance during the reconciliation process.

The half-life of a radioactive kind of europium is 15 years. If you start with 90,624 grams of it, how much will be left after 75 years?
Answer: To determine how much of the radioactive europium will be left after 75 years, we can use the half-life formula:
Amount remaining = Initial amount * (1/2)^(time elapsed / half-life)
Given that the half-life of the radioactive europium is 15 years and the initial amount is 90,624 grams, we can substitute these values into the formula:
Amount remaining = 90,624 * (1/2)^(75 / 15)
Calculating the exponent first:
(75 / 15) = 5
Substituting this back into the formula:
Amount remaining = 90,624 * (1/2)^5
Simplifying the exponent:
(1/2)^5 = 1/32
Substituting this back into the formula:
Amount remaining = 90,624 * 1/32
Simplifying the calculation:
Amount remaining = 2,832 grams
Therefore, after 75 years, there will be approximately 2,832 grams of the radioactive europium left.
Devi bought 7 skits at $x each, n skirts at $12 each, (2n+1) skirts at $15 each and 4 skirts at $3x each. find the total costs of the skirts she bought.
(pls give step by step answers!!)
The total cost of the skirts Devi bought is $19x + $42n + $15. The cost can be calculated by multiplying the number of skirts (4) by the cost per skirt ($3x).
To find the total cost of the skirts Devi bought, we need to calculate the sum of the costs of each type of skirt.
Let's break down the cost of each type of skirt:
Cost of 7 skirts at $x each: The cost can be calculated by multiplying the number of skirts (7) by the cost per skirt ($x).
Cost = 7 * $x = $7x
Cost of n skirts at $12 each: The cost can be calculated by multiplying the number of skirts (n) by the cost per skirt ($12).
Cost = n * $12 = $12n
Cost of (2n+1) skirts at $15 each: The cost can be calculated by multiplying the number of skirts (2n+1) by the cost per skirt ($15).
Cost = (2n+1) * $15 = $15(2n+1) = $30n + $15
Cost of 4 skirts at $3x each: The cost can be calculated by multiplying the number of skirts (4) by the cost per skirt ($3x).
Cost = 4 * $3x = $12x
Now, let's calculate the total cost by summing up the costs of each type of skirt:
Total Cost = Cost of 7 skirts + Cost of n skirts + Cost of (2n+1) skirts + Cost of 4 skirts
Total Cost = $7x + $12n + $30n + $15 + $12x
Total Cost = $7x + $12x + $12n + $30n + $15
Total Cost = $19x + $42n + $15
Therefore, the total cost of the skirts Devi bought is $19x + $42n + $15.

D:The femur length for someone with an expected height of 44 centimeters.
The length of the femur in Centimeters for an individual who has an expected height of 169 centimeters based on the given linear relationship between femur length and expected height.
The formula h = 63.8 + 2.39f represents the relationship between the length of someone's femur (f) and their expected height (h) in centimeters. To determine the meaning of the f-value when h = 169, we need to solve the equation for f.
Given that h = 169, we can substitute this value into the formula:
169 = 63.8 + 2.39f
To isolate the f-term, we can subtract 63.8 from both sides:
169 - 63.8 = 2.39f
105.2 = 2.39f
To find the value of f, we divide both sides by 2.39:
105.2 / 2.39 = f
The approximate value of f is 44.019. Therefore, the meaning of the f-value when h = 169 is:

Calculate the reciprocal of -0. 06, correct to 1 decimal place
The reciprocal of -0.06 is 1666.7.
To calculate the reciprocal of -0.06, we can use the definition of a reciprocal, which states that the reciprocal of a number is 1 divided by that number.
Reciprocal = 1 / Number
In this case, the number is -0.06. Therefore, we have:
Reciprocal = 1 / (-0.06)
To simplify, we can multiply both the numerator and the denominator by -100 to remove the decimal point:
Reciprocal = -100 / (-0.06)
Simplifying further, the negative signs cancel out:
Reciprocal = 100 / 0.06
Now, we can perform the division:
Reciprocal ≈ 1666.6667
Rounding to one decimal place, the reciprocal of -0.06 is approximately 1666.7.
The reciprocal of a number is the value that, when multiplied by the original number, yields a product of 1. In this case, if we multiply -0.06 by its reciprocal (1666.7), the result would be very close to 1 (-0.06 * 1666.7 ≈ -0.9999).

The number of crimes that occurred in a certain city per 1000 people had decreased from 45.3 in 1920 to 44.3 in 1970. Find the average rate of change in the number of crimes per 1000 people that occurred from 1920 to 1970.
The average rate of change in the number of crimes per 1000 people in a certain city from 1920 to 1970 was a decrease of 0.1 crimes per 1000 people per year.
To find the average rate of change, we can use the formula:
Average rate of change = (final value - initial value) / (final year - initial year)
In this case, the initial value is 45.3 crimes per 1000 people in 1920, and the final value is 44.3 crimes per 1000 people in 1970. The initial year is 1920, and the final year is 1970.
Substituting the values into the formula, we get:
Average rate of change = (44.3 - 45.3) / (1970 - 1920)
= (-1) / 50
= -0.02 crimes per 1000 people per year
Therefore, the average rate of change in the number of crimes per 1000 people from 1920 to 1970 is a decrease of 0.02 crimes per 1000 people per year. This means that, on average, the number of crimes per 1000 people decreased by 0.02 every year during that period.

A number cube, labeled 1-6, is rolled 4
times. What is the probability that cube
will land on an even number three out of
four rolls?
When rolling a number cube four times, the probability of obtaining an even number in three of the four rolls is 1/4.
To calculate the probability that a number cube will land on an even number three out of four rolls, we need to consider the total number of possible outcomes and the number of favorable outcomes.
The total number of possible outcomes when rolling a number cube four times is 6^4, which is equal to 1,296. This is because each roll has six possible outcomes (numbers 1 to 6), and the rolls are independent events, so we multiply the number of outcomes for each roll.
Now, let's consider the favorable outcomes. We want the cube to land on an even number three out of four times. There are two cases that satisfy this condition: either the first, second, and third rolls are even, or the second, third, and fourth rolls are even.
Case 1: First, second, and third rolls are even.
The probability of rolling an even number on a single roll is 3/6, or 1/2 since there are three even numbers (2, 4, and 6) out of six total numbers on the cube.
So, the probability of the first, second, and third rolls being even is (1/2) * (1/2) * (1/2) = 1/8.
Case 2: Second, third, and fourth rolls are even.
Again, the probability of rolling an even number on a single roll is 1/2.
So, the probability of the second, third, and fourth rolls being even is (1/2) * (1/2) * (1/2) = 1/8.
Now, we need to add the probabilities from both cases because we are interested in the probability of either of these events occurring:
1/8 + 1/8 = 2/8 = 1/4.
Therefore, the probability that the cube will land on an even number three out of four rolls is 1/4.

Alexa was riding her motorcycle on a freeway at 480 kilometers north of her exit. She was riding south toward the exit at a constant velocity. If it took her 2 hours to get one quarter of the way to her exit. What was her velocity
Let's solve the problem step by step:
1. Alexa was riding her motorcycle on a freeway at 480 kilometers north of her exit.
2. She was riding south toward the exit at a constant velocity.
3. It took her 2 hours to get one quarter of the way to her exit.
Let's denote Alexa's velocity as [tex]\(v\)[/tex] (in kilometers per hour) and the total distance to her exit as [tex]\(D\)[/tex] (in kilometers).
According to the information given, Alexa traveled one quarter of the total distance in 2 hours. This can be represented by the equation:
[tex]\(\frac{1}{4} \times D = v \times 2\)[/tex]
Simplifying this equation, we have:
[tex]\(\frac{D}{4} = 2v\)[/tex]
Next, we know that Alexa started 480 kilometers north of her exit. So the total distance to her exit is:
[tex]\(D = 480 + \text{distance traveled}\)[/tex]
Substituting this expression for [tex]\(D\)[/tex] into our equation, we get:
[tex]\(\frac{480 + \text{distance traveled}}{4} = 2v\)[/tex]
Simplifying further:
[tex]\(120 + \frac{\text{distance traveled}}{4} = 2v\)[/tex]
From this equation, we can see that the velocity [tex]\(v\)[/tex] is independent of the distance traveled. Therefore, the velocity [tex]\(v\)[/tex] remains constant.
To determine the exact value of [tex]\(v\)[/tex], we need more information about the distance traveled by Alexa.
Please provide the additional information, such as the distance traveled or the time taken to cover a specific distance, to calculate the velocity accurately.
