Answer:
the median will go up 2.5 points from 76 to 78.5
Step-by-step explanation:
You want to know the effect on the median of adding 85 to the list of scores: 76, 96, 81, 69, 41.
MedianThe median is the middle value when the list is sorted into order. The ordered list is ...
41, 69, 76, 81, 96
The median is 76.
New MedianWhen 85 is added to the list, the sorted list becomes ...
41, 69, 76, 81, 85, 96
There are two middle scores, so the median is their average:
(76+81)/2 = 78.5
The median increases 2.5 points from 76 to 78.5 when the score is added.
f(x) = -1/2x^2 + 3/2x - 2 I need to find the zeros
Answer:
{-1, 4}
Step-by-step explanation:
In the given f(x) = -1/2x^2 + 3/2x - 2
set f(x) = 0 and then multiply all the numeric terms by -2 to remove the fractions:
f(x) = -1/2x^2 + 3/2x - 2 = 0 => 1x^2 - 3x - 4 = 0
This factors into (x - 4)(x + 1) = 0, whose roots are {-1, 4}. These are the zeros.

The value u > -16 that makes the inequality 5u > -80 is true.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
We have the inequality,
5u > -80
To find the solution set of the inequality;
Divide by 5 to both sides,
5u/5 > -80/5
u > -16.
That means, the inequality is true for u > -16.
Therefore, the inequality is true for u > -16.

Carlton is using the following data samples to make a claim about the house values in his neighborhood:House ValueA $100,000B $600,000C $650,000D $700,000E $900,000Based on the data, should Carlton use the mean or the median to make an inference about the house values in his neighborhood?He should use the median because there is an outlier that affects the mean.He should use the mean because there are no outliers that affect the mean.He should use the mean because it is in the center of the data.He should use the median because it is in the center of the data.
The option A "He should use the median because there is an outlier that affects the mean." is correct.
It is clear from the data that option E's house is much more expensive than those in the other options. A $9,00,000 price is therefore an outlier in this set of data.
In symmetrically distributed data, an inference is made using the mean. Due to the inclusion of an outlier, the data is not symmetrical. As a result, the mean won't accurately depict the data's centre. As a result, we shall refrain from drawing conclusions about the pricing of the residences using the mean.
Therefore, since the median is unaffected by outliers, we shall use it.
Therefore, since there is an outlier that influences the mean, we will utilise the median. The answer is (A).
Your sincere criticism is crucial for better outcomes.

The volume of a cylinder would be the area of the circle times the height of the cylinder. The height of the cylinder represents how many circles are in the stack.
The explanation can be used to informally derive the formula for the volume of a cylinder, which is the correct answer would be option (D).
What is a cylinder?Usually, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric forms. It is a prism with a circle as its basis in elementary geometry. In some recent fields of geometry and topology, a cylinder can alternatively be defined as an infinite curved surface.
Given that, Which explanation can be used to informally derive the formula for the volume of a cylinder
We know that the volume of a cylinder = πr²h
So, consider option (D).
A cylinder is similar to a circular stack. The volume of the cylinder would be equal to the area of the circle multiplied by the cylinder's height. The height of the cylinder reflects the number of circles in the stack.
Therefore, we get the formula πr²h, where πr² represents the area of the circle and h the height of the circle.
Hence, With this reasoning, we may get the formula for cylinder volume informally.

What is the value of N mean?In mathematical operations, “n” is a variable, and it is often found in equations for accounting, physics and arithmetic sequences. A variable is a letter or symbol that stands for a number and is used in mathematical expressions and equations. In an arithmetic sequence, which is a list of numbers that follow a pattern, “n” is a variable representing the number of the term to find.For instance, if students want to find the value of the seventh term, “n” would be 7. In physics, an equation for standing waves uses “n” as an integer symbolizing the harmonic number or number of antinodes. The equation evaluates the length of the string in terms of its wavelength. In accounting, “n” is used in the equation for compound interest. It represents the number of compounding in 1 year.We are given the information that Sonji has 21 dimes (which means that d=21). We can use the equation to find the number of nickels n.

probability:
a) A family wants to have 4 children. Design and do a simulation to determine the probability that, if they do have 4 children, they will have two boys and two girls. (Hint: Use coins.)
b) A basketball player is shooting free throws blindfolded. He shoots in groups of 4 shots. Assume that it is equally likely that he will hit or miss a shot. Design and do a simulation to determine the probability that he will hit at least 75% of his shots within the groups. (Hint: Use coins.)
a) A simulation of the probability that a family with 4 children will have 2 boys and 2 girls can be done using coins. We can represent boys as heads (H) and girls as tails (T).
To simulate the birth of one child, we will flip a coin. If it comes up heads, it represents the birth of a boy, and if it comes up tails, it represents the birth of a girl. We will repeat this process four times to simulate the birth of four children.
We can use the simulation to estimate the probability of the family having 2 boys and 2 girls. We can do this by performing the simulation multiple times (e.g. 100, 1000 or more) and counting the number of times that the family has 2 boys and 2 girls.
The probability can be calculated by dividing the number of successful outcomes (2 boys and 2 girls) by the total number of simulations.
b) A simulation of the probability that a basketball player will hit at least 75% of his shots within the groups can be done using coins. We can represent hitting a shot as heads (H) and missing a shot as tails (T). To simulate one shot, we will flip a coin. If it comes up heads, it represents hitting the shot, and if it comes up tails, it represents missing the shot. We will repeat this process four times to simulate the shooting of four shots.
To determine the probability of hitting at least 75% of the shots, we will perform the simulation multiple times (e.g. 100, 1000 or more) and count the number of times that the player hits at least 3 out of 4 shots.
The probability can be calculated by dividing the number of successful outcomes (3 or 4 shots hit) by the total number of simulations

What are the 5 operations of functions?
The 5 operations of functions are
1. Input
2. Processing
3. Output
4. Storage
5. Maintenance
Input: When a function is used, it takes in an input value. This input value is used to compute the output. For example, if a function is used to calculate the area of a circle, the input would be the radius of the circle.
Processing: Once the input value is taken, the function will use the input to perform some type of operation on it. For example, if the function is used to calculate the area of a circle, the operation would be to multiply the input by itself and then multiply it by the constant pi.
Output: The output of a function is based on the input. For example, if the function is used to calculate the area of a circle, the output would be the area of the circle.
Storage: Once the output of a function is computed, it can be stored for later use. This allows the same output to be used multiple times without having to recalculate the output.
Maintenance: Functions need to be maintained and updated over time. This can include updating the input, operation, and output, as well as any additional changes that might be needed. This ensures the function is up-to-date and still provides accurate results.
