What is the standard deviation for the following dataset?
18 22 39 48 77 89
The standard deviation for the dataset is 28.89.
What is the standard deviation?
When we measure diversity in a data set, it is called standard deviation. We have to calculate the variance first. The square root of variance gives the standard deviation. The formula to calculate standard deviation is:
s= [tex]\sqrt{\frac{(x1-xm)^{2} + (x2-xm)^{2} +........+ (xn-xm)^{2} }{n-1} }[/tex]
First, we will calculate the mean of the data, xm
[tex]xm=\frac{18+22+39+48+77+89}{6}[/tex]
[tex]=48.83[/tex]
Then, we will calculate the following:
[tex](x1-xm)^{2}=(18-48.83)^{2} \\\\(x2-xm)^{2}=(22-48.83)^{2} \\\\(x3-xm)^{2}=(39-48.83)^{2} \\\\(x4-xm)^{2}=(48-48.83)^{2} \\\\(x5-xm)^{2}=(77-48.83)^{2} \\\\(x6-xm)^{2}=(89-48.83)^{2} \\[/tex]
The summation comes out to be 4174.83.
Therefore, the standard deviation becomes = [tex]\sqrt{\frac{4174.83}{5} }[/tex]

A normal distribution is observed from the number of points per game for a certain basketball player. The mean for this distribution is 20 points and the standard deviation is 3 points. Use the empirical rule for normal distributions to estimate the probability that in a randomly selected game the player scored less than 26 points. Provide the final answer as a percent rounded to one decimal place.
Answer: The empirical rule for normal distributions states that for a normal distribution with mean μ and standard deviation σ:
Approximately 68% of the data falls within one standard deviation of the mean, i.e., in the interval (μ - σ, μ + σ).
Approximately 95% of the data falls within two standard deviations of the mean, i.e., in the interval (μ - 2σ, μ + 2σ).
Approximately 99.7% of the data falls within three standard deviations of the mean, i.e., in the interval (μ - 3σ, μ + 3σ).
In this problem, the mean is μ = 20 points and the standard deviation is σ = 3 points. To estimate the probability that the player scored less than 26 points, we need to find the z-score for the value 26, which is given by:
z = (x - μ) / σ = (26 - 20) / 3 = 2
Using the empirical rule, we know that approximately 95% of the data falls within two standard deviations of the mean. Therefore, the probability that the player scored less than 26 points is approximately:
P(X < 26) = P(Z < 2) ≈ 0.9772
Converting to a percentage and rounding to one decimal place, we get:
P(X < 26) ≈ 97.7%
Therefore, the estimated probability that the player scored less than 26 points in a randomly selected game is 97.7%.

Dennis charges $1.75 for gasoline plus $7.50 per hour for mowing lawns. Which inequality represents xx, the number of hours Dennis must work to earn at least $100?
Dennis must work for at least 10.81 hours to earn at least $100.
What is inequality in mathematics?
An inequality in mathematics is a statement that compares two values or expressions using one of the inequality symbols: < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
For example, x < 5 is an inequality that says that the value of x is less than 5. Another example is y ≥ 2x + 3, which is an inequality that says that the value of y is greater than or equal to 2 times x plus 3.
Inequalities are often used to describe ranges of values, such as the set of all numbers that are less than or equal to 5 (written as x ≤ 5) or the set of all numbers that are greater than 2 and less than 7 (written as 2 < x < 7). Inequalities can be solved, graphed on a number line, and used to make comparisons between values or expressions.
Let's start by writing an expression for the total amount of money Dennis earns in x hours:
Total earnings = 1.75x + 7.5x
Simplifying this expression, we get:
Total earnings = 9.25x
Now, we want to find the inequality that represents the number of hours Dennis must work to earn at least $100. We can set up the inequality as follows:
9.25x ≥ 100
This inequality states that Dennis must earn at least $100, which is represented by the value on the right-hand side of the inequality. The left-hand side of the inequality represents Dennis's earnings, which we found to be 9.25x. Since we want to find the minimum number of hours Dennis must work to earn at least $100, we need to solve for x:
9.25x ≥ 100
x ≥ 100/9.25
Simplifying the right-hand side of the inequality, we get:
x ≥ 10.81
Therefore, the inequality that represents the number of hours Dennis must work to earn at least $100 is:
x ≥ 10.81
This means that Dennis must work for at least 10.81 hours to earn at least $100.

A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 54 months and a standard deviation of 11 months. Using the 68-95-99.7 rule, what is the approximate percentage of cars that remain in service between 21 and 32 months?
Therefore , the solution of the given problem of percentage comes out to be 11.31% of the vehicles in use are between 21 and 32 months old.
Describe percentages.In statistics, a percentage is a figure or a figure that is expressed as a fraction of 100. Furthermore, "pct.," "pct," as well as "pc," are rarely used. However, it is commonly denoted by the "%" sign. There are no dimensions; the percentage total is flat. Percentages are essentially numbers because their numerator is 100. To indicate that a number is a percentage, the percent sign (%) or the phrase "percent" must appear before the number.
Here,
This rule states that for a normal distribution, which is presumed here because of the bell-shaped curve:
The data is within yet another standard deviation of the median for 68% of the time.
The data is within 2 standard deviations of the median for 95% of the time.
The data is now within three standard deviations of the mean in 99.7% of the cases.
As a result, z1 = (21 - 54) / 11 = 3 and z2 = (32 - 54) / 11 = 2
The numbers -3 and -2 represent the number of standard deviations that each figure is from the mean.
determine what percentage of the data lies in between two values:
P(-3 ≤ Z ≤ -2) = 0.1359 - 0.0228 = 0.1131
According to this, 11.31% of the vehicles in use are between 21 and 32 months old.

sebastian is creating a rectangular garden in his backyard. the length is 11 feet. the perimeter of the garden must at least be 56 feet and no more than 76 feet. what is the width of the garden must at least be?
The garden must be at least 17 feet wide.
Let's use w to represent the garden's breadth.
The perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width.
Assuming that the length is 11 feet, the expression for the perimeter can be written as follows:
P = 2(11) + 2w = 22 + 2w
The perimeter is stated to be at least 56 feet and not to exceed 76 feet. Hence, we can create the inequality shown below:
56 ≤ 22 + 2w ≤ 76
When we take 22 out of every aspect of the inequality, we get:
34 ≤ 2w ≤ 54
By multiplying every aspect of the inequality by 2, we obtain:
17 ≤ w ≤ 27
Thus, the garden must be at least 17 feet wide.

Julio wears a blue shirt every 3 days. Larry wears a blue shirt every 4 days.on April 12 ,both Julio and Larry wore blue shirt.what is the next date that they will both wear a blue shirt?
Answer:
Step-by-step explanation:
We need to find the least common multiple (LCM) of 3 and 4, which will give us the number of days after which both Julio and Larry will wear a blue shirt on the same day again.
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
The multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, ...
We can see that the least common multiple of 3 and 4 is 12, because it is the smallest number that appears in both lists.
This means that Julio and Larry will wear a blue shirt on the same day every 12 days.
Since they both wore blue shirts on April 12, the next date that they will both wear a blue shirt is 12 days later, on April 24.
Answer:
To find the next date that they will both wear a blue shirt, we need to find the least common multiple (LCM) of 3 and 4, which is 12.
So, Julio will wear a blue shirt on April 12, 15, 18, 21, and so on.
Larry will wear a blue shirt on April 12, 16, 20, 24, and so on.
The next date they will both wear a blue shirt is when their dates coincide, which is April 24.
Therefore, Julio and Larry will both wear a blue shirt again on April 24.

Answer:
212.5ft^2
Step-by-step explanation:
First, go ahead and find the area of the total square. To do this, multiply the length by the height (15*15) to get 225. This is not our final answer, but it will help us solve the problem later.
Next, we need to find the area of the lower-left triangle that is cut off. To do this, we will find the side lengths of just that section. Because the left side of the square and the right side are the same total length, we can just subtract 10 from 15 to get a length of 5.
Now, to find the area of the triangle we will use b*h/2:
5*5/2=12.5
All that's left is to subtract this area from the initial area (225) to get our final answer of 212.5ft^2.
