Answer: Variance = 0.858

Step-by-step explanation: The variance formulae for a probability distribution is given below as

Variance = √npq

Where n = number of times experiment was performed = 9

p = probability of success = 0.09

q = probability of failure = 1 - p = 1 - 0.09 =0.91

Variance = √9×0.09×0.91

Variance = √0.7371

Variance = 0.858

For x=2

substitute

\begin{gathered} P(x)=\operatorname{\ln}\lvert4(2)+1\rvert+3(2)-(2)^2 \\ P(x)=\operatorname{\ln}\lvert9\rvert+2 \\ P(x)=4.20\text{ millions of dollars} \end{gathered}

_______

Note that the "611" ; after the decimal point;  this goes to the "thousandths";  

place (is "3 (three) digits long.").

_______

As such; we rewrite the number as:

_______

" \frac{33.611}{1} " ;  

and we multiply BOTH the "numerator" And the "denominator" by: "1000" :

_______

  →  " \frac{(33.611)*(1000)}{(1)*(1000)} " ;

to get:

  →  " \frac{33611}{1000} " ;  →  which cannot be reduced any further.

_______

The correct answer is: " \frac{33,611}{1,000} " .

_______

There are three consecutive integers such that the sum of the two smallest integers is 17 less than three times the largest.What
abruzzese [7]
ANSWER:

Let the smallest integer = x

x + x + 1 = 3 ( x + 2 ) - 17

2x + 1 = 3x + 6 - 17

2x - 3x = 6 - 17 - 1

- x = - 12

x = 12

FINAL ANSWER:

Therefore, the smallest integer is 12.

The Kroger Company is one of the largest grocery retailers in the United States with over two thousand grocery stores across the
Ilia_Sergeevich [38]

Answer:

1) Categorical

2) Norminal

Step-by-step explanation:

1)

The data collected by Kroger in this example categorical or quantitative identified below:

From the given information, Kroger uses an online customer opinion to obtain the data about its products and services. All the questions based on yes or no type questions. Here the questions are ‘products that have a brand name, products that are environmentally friendly, products that are organic’ these type of questions cannot be expressed numerically so the data collected by Kroger Company is categorical variable because these answers of the questions cannot be counted.

Any variable which is grouped into two or more attributes then it is a categorical variable. The data collected by Kroger Company is categorical variable and any variable which can be counted or measured in numerical then it is quantitative variable.

2)

The measurement scale is identified below:

Here the variable cannot be counted in numerical sale so the level of measurement cannot be ratio, interval because ratio and interval scale can be used for numerical data. The nominal scale can be used to identify the ‘products that have a brand name, products that are environmentally friendly, products that are organic, products that have been recommended by others’ because natural order need not be used.

The ratio and interval scale can be used for Quantitative data and nominal and ordinal scale can be used for Qualitative data. When the order is needed to categorize the objects Ordinal scale is used, when the order is not needed to categorize the objects Nominal scale is used.
