We don’t know the number of employees remaining at the company.

We don’t know the total number of employees remaining at the company.

The classification consists of gender, division, and employment type.

It doesn’t matter what order those attributes come in. A person who is male, age group 6, and employment type 10 has the same classification as someone who is of employment type 6, male, and age group10.

Therefore since order does not matter it is a combination question.

Assuming only two genders are allowed (you didn’t say and some people think there are about 10 of them)

It is either 120 (2 times 6 times 10) or "None of the above" if you believe there are more than 2 genders.

2×6×10=120

Answer: The answer to the question is Answer Choice "B"

Step-by-step explanation:

Proof that It's actually correct as you can see it on the screenshot :)

The given multipliers are factors of 9, the possible number will have 1 as first and last digit which gives the number as 101

The given numbers are;

18, 27, 36, 45, 54, 63, 72, 81, 99

Given that the first and the last figures are those of the multipliers, we have;

The first and last and last digit of the number can be 1, which gives;

Possible numbers includes; 11 and 101

By trying the possible numbers, the difference found is presented as follows;

99 × 11 = 1089 (The first and the last digit are not the same as the multiplier)

90 × 11 = 990

90 × 101 = 9090

The correct option is therefore 101

Answer:

about 8.2 cm

Step-by-step explanation:

The key is to realize that the volume never changes.
The formula for the volume of a sphere is (4/3)*pi*radius^3
22/7 is being substituted in place of pi in this problem
The volume of one of the small spheres is
(4/3)*(22/7)*2^3 is about 33.524 cm^3
64 of those spheres would have a volume of 33.524*64, or about 2145 cm^3
Now, the problem is to find a sphere with a volume of 2145 cm^3
Volume = (4/3)*(22/7)*radius^3
plug in and solve
2145 = 4.1905*r^3
r^3=511.87
r is about equal to 8.2 centimeters

a)The purpose of statistical inference is to make estimates or draw conclusions about a population based upon information obtained from the sample.

Statistical inference is the process of drawing conclusions about populations or scientific truths from data. There are many ways to make inferences, including statistical modeling, data-driven strategies, and the explicit use of designs and randomization in analyses.

Hypothesis testing is a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or population probability distribution.

First, a preliminary assumption is made about the parameter or distribution. This assumption is called the null hypothesis and is denoted H0.

An alternative hypothesis (denoted Ha) is then defined, which is the opposite of what is stated in the null hypothesis. The hypothesis testing procedure involves using sample data to determine whether or not H0 can be rejected. If H0 is rejected, the statistical conclusion is that the alternative hypothesis Ha is true.

A measure of the strength of the relationship between two variables is referred to as the correlation coefficient.

Correlation coefficients are used to evaluate the strength of the linear relationship between two variables.

When the correlation coefficient value is less than zero, it indicates a bad association, while a number higher than zero indicates a good relationship.

There is no correlation between the two variables being compared, as shown by a correlation coefficient of zero.

The idea of a negative correlation, also referred to as an inverse correlation, is essential to the construction of diversified portfolios that may be better able to withstand portfolio volatility.

It is often done by entering data into a calculator, computer, or statistics application because computing the correlation coefficient requires time.

Step-by-step explanation:

Adriana

E (earnings) = 6 + 2*x where x is the number of subscriptions

Sophie

E (earnings) = 4 + 3x

For them to earn the same amount, their right sides must be equated.

4 + 3x = 6  + 2x                    Subtract 2x from both sides

4 + 3x - 2x = 6+ 2x  - 2x       Combine

4 + x = 6                                Subtract 4 from both sides

Step-by-step explanation:

Let X be the total number of books, made up of nonfiction, animal, and all others.

(3/5)X are nonfiction books.

Of the nonfiction books, 1/4 are animal books:  (3/5)*(1/4)X = (3/20)X are animal books

Animal books make up (3/20) of all books.

The statement "The value of a is positive, so the vertex is a minimum" is correct.

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

The question is incomplete.

From the table we can find the quadratic function:

f(x) = ax² + bx + c

Plug (x, y) on the above function.

a + b + c = 3 ...(1)

9a + 3b + c = -3 ...(2)

25a + 5b + c = -5 ...(3)

Frequency is a physical quantity that relates to the number of cycles made by a wave per second. Therefore the required expression for the frequency of the lower note is:  [tex]\frac{2}{3}[/tex] f

A wave is a phenomenon that propagates through a material medium without any permanent effect on the molecules of the medium. It transmits energy from one end of the medium to another. Examples are sound waves, light waves, electromagnetic waves, etc.

The propagation of a wave gives rise to frequency. Which can be defined as the number of cycles made by a wave per second. And it is measured in Hertz.

Let the frequency of the higher note be represented by f, and that of the lower note by [tex]f_{l}[/tex]. Thus, we have;

[tex]f_{l}[/tex] = [tex]\frac{2}{3}[/tex] f

b) x = 1

Step-by-step explanation:

a) [tex]\frac{4x-1}{2} = x + 7[/tex] multiply both sides by 2 so we can simplify the fraction by getting rid of 2

4x - 1 = 2x + 7 transfer like terms to the same side of the equation

4x - 2x = 7 + 1

2x = 8 divide both sides by 2

x = 4

b) [tex]3x + 2 = \frac{2x+13}{3}[/tex] again, get rid of the fraction by multiplying both sides by 3

9x + 6 = 2x + 13 transfer like terms to the same side of the equation
