is the following statement true or false? all other things being equal, outliers tend to have a greater effect on the value of the mean, as compared to the value of the median.

Answers

All other things being equal, outliers tend to have a greater effect on the value of the mean, as compared to the value of the median. The given statement is true.

What is the mean and median?

Outliers are values that are significantly different from the other values in a data set, and their presence can greatly affect the value of measures of central tendency, such as the mean and the median.

The mean is a measure of central tendency that is calculated as the sum of all the values in a data set divided by the number of values. The presence of outliers can greatly affect the mean because outliers can have a large impact on the sum of the values in the data set. For example, if a data set has a few very large outliers, the mean will be pulled up to be much higher than the median, which represents the midpoint of the data set.

On the other hand, the median is a measure of central tendency that is calculated as the middle value of a data set when the values are arranged in order. The median is not as sensitive to outliers as the mean because outliers do not affect the median unless the number of outliers is so large that it changes the value of the middle value.

Hence, all other things being equal, outliers tend to have a greater effect on the value of the mean than on the value of the median.

What is the simplified form of 4 log3x + 6 log3y - 7 log3z?

Answers

The simplified form of 6 log₃x - 7 log₃y + 4 log₃z is  log₃{(x⁶z⁴)/y⁷}.

What are exponents?

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You can write this as 64. In this case, the exponent is 4 and the base is 6.

The simplification of the provided logarithmic expression can be done as follows:-

6 log₃x - 7 log₃y + 4 log₃z,

= log₃x⁶ - log₃y⁷ + log₃z⁴ {Using the Power law}

= log₃x⁶ + log₃z⁴ - log₃y⁷

= log₃x⁶z⁴ - log₃y⁷ {Using the Product law}

= log₃{(x⁶z⁴)/y⁷} {Using the Quotient law}.

Hence, the simplified form of 6 log₃x - 7 log₃y + 4 log₃z is  log₃{(x⁶z⁴)/y⁷}.

Answers

The optimum sampling strategy is (iii), which is listed below.

By selecting a student's initial name from each page of the cam pus phone book, you may measure the heights of the chosen pupils.

What is Sampling?

Sampling is a technique for selecting a small group of people or a subset of the population in order to make generalizations and estimate the features of the population. In order to acquire relevant information without studying the entire society, researchers commonly use a variety of sampling approaches in market research.

To ascertain the average height of all students at a certain institution and guarantee that the result is statistically reliable, the sampling process must be applied.

a. Measure the heights of 50 students found in the gym during basketball intramurals.

This approach is not ideal since you would only sample basketball players while leaving all other university students out; hence, your sample would not be representative of all students, simply those who play basketball.

b. Measure the heights of all engineering majors.

This approach is flawed since the sample exclusively includes engineering majors, leaving out students studying other courses.

c. Measure the heights of the students selected by choosing the first name on each page of the campus phone book.

This strategy, which is the finest of the three, allows you to select students independent of the sport or subject they are pursuing. It is more representative of the university student population.

A ball thrown upwards hits a roof and returns back to the ground.
The upward movement is modeled by a function s=−t2+3t+4
and the downward movement is modeled by s=−2t2+t+7
, where s is the distance (in metres) from the ground and t
is the time in seconds.
Find the height of the roof from the ground.

Answers

Answer: To find the height of the roof, we need to find the point where the ball reaches the maximum height, i.e., the point where the velocity of the ball is equal to 0.

The velocity of the ball can be found by taking the derivative of the function s. The derivative of the function s = −t^2 + 3t + 4 is given by v = ds/dt = 3 − 2t, and the derivative of the function s = −2t^2 + t + 7 is given by v = ds/dt = 1 − 4t.

Setting v = 0, we get 3 − 2t = 0 and t = 3/2 seconds.

Plugging t = 3/2 seconds into the first equation, s = −t^2 + 3t + 4, we get s = −(3/2)^2 + 3(3/2) + 4 = 9/4 + 9/2 + 4 = 7 metres.

Therefore, the height of the roof from the ground is 7 metres.

determine if the statements are true or false. an even degree polynomial must be an even function. true false every polynomial of odd degree has at least one zero. true false every rational function that is not a polynomial has a vertical asymptote. a. true b. false

Answers

A rational function does not have any factors in the denominator that can be equal to 0, then it will not have a vertical asymptote.

An even degree  must be an even function is true. This is because a polynomial with an even degree has an even-numbered power, such as f(x)=x^2. This means that the function is symmetrical when its graph is reflected over the y-axis. This means that the graph will look the same if the x-values are reflected over the y-axis. For example, if f(3)=9, then f(-3)=9 as well.

Every polynomial of odd degree has at least one zero is true. This is because a polynomial with an odd degree will always have at least one x-value for which the equation is equal to 0. This is because the highest power of the equation must be odd, and the equation must cross the x-axis at least once. For example, f(x)=x^3 will have at least one x-value, such as x=0, where f(x)=0.

Every rational function that is not a polynomial has a vertical asymptote is false. A rational function that is not a polynomial may have a vertical asymptote, but it is not guaranteed. A vertical asymptote is created when the denominator of a rational equation has a factor that is equal to 0. This means that when this factor is equal to 0, the equation has an undefined value. If a rational function does not have any factors in the denominator that can be equal to 0, then it will not have a vertical asymptote.

Number of marbles drawn = 2

a) Sample points are different possible combinations.

  { R,R} , {R,B}, {B, R}, {B,B}

b) Probablitiy of  { R,R} = 3/5 * 2/4 = 6/20 = 3/10 = 0.3

    Probablitiy of {R,B} = 3/5 * 2/4 = 0.3

    Probablitiy of {B,R} = 2/5* 3/4 = 0.3

     Probablitiy of {B,B} = 2/5 * 1/4 = 0.1

c) A: { Two blue marbles are drawn. }

    Probability = 2/5 * 1/4 = 0.1

  B:{ A red and a blue marble are drawn. }

Suppose a function f(x) is defined on the domain [-8,4]. If we define a new function g(x) by g(x) = f(-2x), then what is the domain of g(x)? Express your answer in interval notation

Answers

The required domain of the function If g(x) = f(-2x) is [-16, 8] in interval notation.

How to find domain of function?

The domain of g(x) is the set of all x for which the function g(x) is defined. If g(x) = f(-2x), then the domain of g(x) is the same as the domain of -2x, subject to the restriction that f(x) is defined for the corresponding values of x.

According to question:

In interval notation, the domain of -2x is (-∞, ∞).

However, since f(x) is defined only on the interval [-8, 4], the domain of g(x) must be restricted to values of x that correspond to values of -2x within the interval [-8, 4].

To find the corresponding values of x, we need to solve the equation -2x = t for x, where t is a number in the interval [-8, 4].

Solving for x, we get x = -t/2. So, the domain of g(x) is the set of all x such that -t/2 is in the interval [-8, 4], or equivalently, t is in the interval [-16, 8]. In interval notation, this is [-16, 8].

So, the domain of g(x) is [-16, 8] in interval notation.
