Factor by using the perfect-square trinomial formula.

100x^2+20x+1

Answers

Answer 1
Answer: to factor first multily 100 and 1 and get 100

then find what 2 numbers multiply to get 100 and add to get 20

the numbers are 10 and 10

so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
Answer 2
Answer: sincethis is a perfect square problem, the answer will be in the form (ax +b) ^ 2. what can you tell from looking at the original equation? x^2does not have a coefficient in front of it, so a = 1. the second term isnegative, so b must be negative. finally, the last number 100 is thesquare of + or - 10, so b must be +10 or -10, but we already figured bhas to be negative, so b = -10

The process of correcting data to reduce them to the sample scale by subtracting the sample mean and dividing by the standard deviation- Options Generalization Scale transformation Standardization Variable re – specification

Answers

Standardization 

Or to produce the one of the statistical concepts, the z-score. The z-score is yielded when the sample mean deducts the observed sample score and is divided by the standard deviation. This is used to standardize the scale into numbers from or before 0.

Which statements are true for irrational numbers written in decimal form? A. Irrational numbers are nonterminating. B. Irrational numbers are repeating. C. Irrational numbers are nonrepeating. D. Irrational numbers are terminating.

Answers

The correct options are A and C because irrational numbers are nonterminating and nonrepeating.

Given:

Some statements for irrational numbers are written in decimal form.

Explanation:

Rational number: A rational number can be defined in the form of (p)/(q),q\neq 0. Rational numbers are either terminating or repeating decimal numbers.

Examples: (3)/(5),2.555...,4.5 etc.

Irrational number: An irrational number cannot be defined in the form of (p)/(q),q\neq 0. Irrational numbers are nonterminating and nonrepeating decimal numbers.

Examples: √(3),\pi ,1.35742784... etc.

Therefore, the correct options are A and C.

The correct answers are

A. Irrational numbers are nonterminating; and C. Irrational numbers are nonrepeating.

Explanation:

Irrational numbers are numbers that cannot be written as rational numbers, or fractions.

Terminating decimals have a specific endpoint; this means we can find the place value of the last digit of the number and write it as a fraction (if it ends in the tenths place, it is a fraction over 10; if it ends in the hundredths place, a fraction over 100; etc.).

Repeating decimals can also be written as a fraction; for example, 0.3 repeating is 1/3; 0.6 repeating is 2/3; 0.1 repeating is 1/9; etc.

This means that irrational numbers must be nonrepeating and nonterminating.
