A quantitative variable that has a finite or countable number of values is called

Answers

Answer 1
A countable quantitative variable that is finite is called a discrete variable while a non finite or infinite quantitative variable is known as a continuous variable. Discrete variables can only be a certain set of numbers while a continuous variable can be any number of values.
Answer 2

A quantitative variable with a countable number of values is known as a discrete variable, which includes whole number counts such as the number of yellow M&Ms or total M&Ms in a sample

A quantitative variable that has a finite or countable number of values is called a discrete variable. Quantitative discrete data such as the number of phone calls received each day can only take certain numerical values, which are typically integers like zero, one, two, or three. This is different from continuous data, which can take any value within a certain range, like weight or percentage values that can include fractions and decimals.

For example, in the case of counting M&Ms, the number of yellow M&Ms and the total number of M&Ms would be discrete data because they can only be whole numbers. In contrast, the weight of the M&Ms in ounces and the percentage that are red are examples of continuous data because these can take on any value, including fractions, within the range.

The distinction between discrete and continuous data is important for selecting appropriate statistical methods for analysis, as certain methods are more suitable for discrete data, while others are better for continuous data

The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 22i. Which statement must be true about the complex numbers?

Answers

Answer: The complex numbers have opposite real numbers.

This a prove of that conclusion:

Let A + Xi be one complex number and B + Yi the other complex number, then:

A + Xi + B + Yi = 0 + 22i

=>  A + B = 0 => A = -B, which means that the real part of one of the complex number is the opposite of the real part of other complex number. The imaginary part is not relevan for the question.

Find the midpoint of the line segment whose endpoints are (0,1/2 ) and (0,3/4 ).

Answers

Formula of the midpoint:
x =(x₁+x₂)/2    and y = (y₁+y₂)/2

Plugin the respective value
for A(0,1/2)  and B(0, 3/4)

x= (0+0)/2 = 0
y = (1/2 + 3/4)/2 = 5/8

A circle with a radius of inches has a central angle of 0.25 radians that intercepts an arc of inches.

Answers

arc length  = c* r    where  c = angle in radians and r = radius

                = 0.25 * 4

                = 1 inch

Answer:

Step-by-step explanation:

Given that there is a circle of .... inches with central angle 0.25 inches

by formula we have arc = radius *central angle in radians

The radii are given three options as 10,20,4 and corresponding arcs as

25,5, 16 inches.

By matching we find that 10(0.25) not equals 25

But 20(0.25) = 5 inches

Also 4(0.25) not equals 16 inches

Hence correct answer is radius = 20 and central arc = 5 inches

For what value of the constant c is the function f continuous on (-infinity, infinity) for the equation f(x) = cx^2 + 2x if x < 2 and x^3 - cx if x> or = 2

Answers

Replace  x  by 2 in th 2 functions and soslve for c:_

4c + 4 = 8 - 2c

6c = 4

c = 2/3

Answer is c = 2/3
Final answer:

To find the constant c that makes the given piecewise function continuous for all real numbers, the two parts of the piecewise function need to be equal at x = 2. By setting these two equal and solving for c, you will find the value that makes the function continuous.

Explanation:

The question presents a piecewise function and asks for which value of the variable c does it become continuous for all real numbers. To make a function continuous at a certain point, both parts of the function must be equal at that point. In this case, the two parts meet at x = 2. We need to set the two parts equal to each other at x = 2 and then solve for c.

For the first part of the piecewise function,

[tex]f(x) = cx^2 + 2x[/tex]

, when we substitute x = 2, it becomes f(2) = 4c + 4.

For the second part of the piecewise function,

[tex]f(x) = x^3 - cx[/tex]

, substituting x = 2 again gives us f(2) = 8 - 2c.

In order for the function to be continuous, these two results must be equal. We set 4c + 4 = 8 - 2c and solve it for c. Solving this equation will provide the value of c for which the function is continuous for all x .

One fourth of a number q is 3 more than three times a number w. Solve for q.

Answers

1/4q = 3w + 3...multiply both sides by 4
q = 4(3w + 3)
q = 12w + 12 <===
Final answer:

To solve for q, multiply both sides of the equation 1/4q = 3 + 3w by 4. This eliminates the fraction and gives us q = 12 + 12w.

Explanation:

To solve for q, we need to translate the given information into an equation. The problem states that one fourth of q is 3 more than three times a number w. Written as an equation, this is represented as:



1/4 q = 3 + 3w



To solve for q, we can multiply both sides of the equation by 4 to eliminate the fraction:



q = 12 + 12w

Answers

If we  draw a perpendicular line from one of the vertices of the triangle we get  2 right angled triangles  each with  altitude 9 ins  and vertex angle = 30 degrees.   So:-

cos 30 = 9 /h     where h = one of the sides of the equilateral triangle

h =  9 / cos 30  =  10.392 inches

Therefore the perimeter of the triangle = 3 * 10.392 =  31.1769 ins

Hello! “x” equals the number of containers. Each container contains 125 flowers. Therefore, C and D are not the right answers. Adding 15,625 to 300,000 would carry you out of your limit. The one equation that works here is A, because you are solving this equation by doing 125x + 15,625 = 300,000. The answer is A.

Which normal distribution has a wider​ spread: the one with mean 3 and standard deviation 4 or the one with mean 4 and standard deviation 3 ​? the normal distribution with mean 4 and standard deviation 3 has the wider spread?

Answers

Answer:

The correct option is 1. The normal distribution with mean 3 and standard deviation 4 has a wider spread.

Step-by-step explanation:

Normal distribution is defined by two variables, mean and standard deviation.

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

The spread of a normal distribution is not dependent on mean, it is completely dependent of standard deviation. Larger standard deviation means wider​ spread.

It is given that first normal distribution has

[tex]\mu_1=3[/tex]

[tex]\sigma_1=4[/tex]

Second normal distribution has

[tex]\mu_2=4[/tex]

[tex]\sigma_2=3[/tex]

Since [tex]\sigma_1>\sigma_2[/tex], therefore the normal distribution with mean 3 and standard deviation 4 has a wider spread.

Hence the correct option is 1.

Final answer:

The normal distribution with a mean of 3 and a standard deviation of 4 has a wider spread than a normal distribution with a mean of 4 and a standard deviation of 3, as the spread is determined by the standard deviation.

Explanation:

The question is asking which of the two normal distributions has a wider spread. The spread of a normal distribution is determined by its standard deviation. A normal distribution with a higher standard deviation will have a wider spread. In this case, the normal distribution with a mean of 3 and a standard deviation of 4 will have a wider spread compared to the normal distribution with a mean of 4 and a standard deviation of 3. Thus, the statement 'the normal distribution with mean 4 and standard deviation 3 has the wider spread' is incorrect.

In a normal distribution, as the standard deviation increases, the distribution curves become wider and shorter, reflecting a greater spread in the data. Because both distributions are normally distributed, we can compare the standard deviations directly to determine the spread: a standard deviation of 4 indicates a wider spread than a standard deviation of 3.

The maximum of f(x) is y = 3. This is the y coordinate of the vertex (6,3). 

Note how y = -4(x-6)^2 + 3 is in the form y = a(x-h)^2 + k, which is vertex form. So we can see that the vertex is (h,k) = (6,3), since h = 6 and k = 3.

Note: This graph is an upside down parabola with (6,3) as the highest point.

---------------------------------------

In contrast, the max of g(x) is y = 6. This is the y coordinate of the highest point on the curve. One such point is (pi/2, 6). There are infinitely max points because the up and down pattern goes on forever.

So g(x) has the larger max compared to f(x).
