Step-by-step explanation:

there are four numbers in this data set we divide by 4 to get the mean which is 6.5/4 = 1.6251.

What  is mean ?

The mean is generally the average of a given set of numbers. It is the value that gives the central tendency from a given set of observations.

In statistics, three measures define the central values of the observed data they are mean, median, and mode

The mean for a given set of numbers can be computed in more than one way, including the arithmetic mean method, which uses the sum of the numbers in the series

The mean of a data set is calculated by adding up all the numbers in the data set and then dividing by the total number of values in the set.

In this case, we have a data set of

{1/2,1/3,2/3,11/2}.

Adding these numbers together gives us

1/2 + 1/3 + 2/3 + 11/2 = 6.5.

Since there are four numbers in this data set,

we divide by 4 to get the mean which is 6.5/4 = 1.6251.

Therefore, the volume of a cycle that is shaped like a cylinder with a height of 150 feet and a radius of 35 feet is 576975 ft^3.

They are asking us to calculate the volume of a cycle, formed by a cylinder (The cycle is shaped like a cylinder).

To calculate the volume, we apply the formula:

We know that the height you have is 150 feet, and the radius is 35 feet, we solve:

V = 3.14 × (35 ft)² × 150 ft

V = 3.14 × 1225 ft² × 150 ft

V = 576975 ft³

Therefore, the volume of a cycle that is shaped like a cylinder with a height of 150 feet and a radius of 35 feet is 576975 ft^3.

(A) This problem cannot be solved by subtracting A and B. If we subtract 1/3 from 1/2, we get 1/6, which is the amount of water that was poured out. However, this does not tell us how much water is left in the bowl. To solve the problem, we need to subtract 1/3 from 1/2 and then subtract the result from 1/2. This gives us

Answer:      from year 3 to 4, percentage is 32%

Step-by-step explanation:       the growth is th largest, showing a difference of eight. and 8% is so little it would not make sense

Using the empirical rule, the percentage of IQ scores that are greater than 79 is 84%.

The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution:

Since we know that the mean is 96 and the standard deviation is 17, we can calculate how many standard deviations away from the mean an IQ score of 79 is:

(79 - 96) / 17 = -1

This means that an IQ score of 79 is one standard deviation below the mean. This also means that approximately 68% of the data falls between 79 and (96 + 17) = 113.

Meanwhile, approximately 32% of the data falls outside of one standard deviation. We can say that half of this 32% are scores less than 79 and the other half are scores greater than 113. So the percentage of IQ scores greater than 79 is:

100 - (1/2 of 32) = 84%

f(x) = (140 + 30x) / 60 for the Orbit company

f(x) = (20 + 35x) / 60 for the Vision company

What is time complexity?

Time complexity refers to the amount of time an algorithm or program takes to run as the input size increases. It is a measure of the efficiency of an algorithm, and it is usually expressed in terms of the "big O" notation.

Cost of Orbit company subscription

= $140 + ($30/month * 12 months * 5 years) = $2140

Cost of Vision company subscription

= $20 + ($35/month * 12 months * 5 years) = $2120

Therefore, the average cost of each satellite television subscription per month for the given period is:

(Cost of Orbit subscription + Cost of Vision subscription) / (12 months * 5 years) = ($2140 + $2120) / (12 * 5) = $35.67 per month

Time complexity O(1), and space complexity V(1) because the calculation only involves basic arithmetic operations and a fixed number of variables.

So, the function to represent the average cost of each satellite television subscription per month would be:

f(x) = (140 + 30x) / 60 for the Orbit company

f(x) = (20 + 35x) / 60 for the Vision company

If the area of a circle is 2.0096 square miles. The circle's radius is 0.8 .

The final form of the exponential function is: f(t) = 750(0.8825)raise to the power t

what is exponential function?

An exponential function is a mathematical function of the form f(x) = a to the power x, where "a" is a positive constant (called the base of the exponential function) and "x" is a variable that can take on any real number value.

The key property of an exponential function is that the output value (or "y" value) grows or decays at a constant rate as the input value (or "x" value) increases or decreases. This constant rate of growth or decay is determined by the base "a" of the function.

When the base "a" is greater than 1, the function represents exponential growth, where the output value increases rapidly as the input value increases. When the base "a" is between 0 and 1, the function represents exponential decay, where the output value decreases rapidly as the input value increases.

Exponential functions are commonly used to model natural phenomena such as population growth, radioactive decay, and compound interest. They also have many applications in science, engineering, economics, and finance.

Starting with the given exponential function:

f(t) = 750(0.65)raise to the power (t/35)

We can rewrite 0.65 as 0.65, and 35 as 5 * 7. Then we have:

f(t) = 750(0.65)raise to the power (t/(5*7))

Using the exponent rule that (a to the power b)to the power c = a to the power (bc), we can simplify the expression inside the parentheses:

f(t) = 750(0.65 to the power (t/5))⁷

Letting a = 750 and b = 0.65 to the  power(1/5), we can write the function in the desired form:

f(t) = ab to the power , where a ≈ 750 and b ≈ 0.8825 (rounded to four decimal places)

Therefore, the final form of the exponential function is:

f(t) = 750(0.8825) to the power t

Expressions are widely used in arithmetic, mathematics, and shape. They are used in the representation of mathematical formulas, the solution of equations, and the simplification of mathematical relationships.

Because the dot plot is not symmetrical and the distribution appears to be skewed towards higher ratings, a rating of 6 may not be a good description of the centre of this data set. The numbers 8, 9, and 10 are more common than the numbers 0-7, indicating that the data set has a right skew.

For example, if y is inversely proportional to x, then we can write it as y = k/x, where k is the constant of variation. As x increases, y must decrease to keep the product of x and y constant.

Answer:

360 adult tickets and 800 student tickets were sold.

Step-by-step explanation:

Let's use a system of equations to solve this problem.

Let x be the number of adult tickets sold, and y be the number of student tickets sold. We know that a total of 1,160 tickets were sold, so:

x + y = 1160

We also know that the total amount collected was $2,600. The amount collected from adult tickets is $5 times the number of adult tickets sold, and the amount collected from student tickets is $1 times the number of student tickets sold. So:

5x + 1y = 2600

Now we have a system of two equations:

x + y = 1160

5x + y = 2600

We can solve for one of the variables in terms of the other, and substitute into the other equation to solve for the remaining variable. For example, we can solve the first equation for y:

y = 1160 - x

Now substitute this expression for y into the second equation:

5x + (1160 - x) = 2600

Simplifying and solving for x:

4x + 1160 = 2600

4x = 1440

x = 360

So 360 adult tickets were sold. To find the number of student tickets sold, we can use either equation. Let's use the first equation:

x + y = 1160

360 + y = 1160

y = 800

So 800 student tickets were sold.

Therefore, 360 adult tickets and 800 student tickets were sold.

The answer is that the z score is unusual. We can calculate it in the following manner.

To calculate the z-score for a score of 72, we can use the formula:

z = (x - μ) / σ

where x is the individual score, μ is the mean, and σ is the standard deviation.

Substituting the given values, we get:

z = (72 - 77) / 2 = -2.5

Rounding to two decimal places, the z-score is -2.50.

To determine if this z-score is unusual, we need to compare it to a standard normal distribution. In a standard normal distribution, about 95% of the data falls within 2 standard deviations of the mean (i.e., between a z-score of -2 and +2). A z-score beyond this range is generally considered unusual.

Since the z-score for a score of 72 is beyond this range (i.e., it is less than -2), it is considered unusual.

Therefore, the answer is:
