Answer:

Part 1) The ordered pair is (0,0)

Part 2) The ordered pair is (-2,-4)

Part 3) The ordered pair is (4,8)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a direct variation

$y=2x$

Complete the ordered pairs

Part 1) we have (0,?)

For x=0

Substitute in the equation and solve for y

$y=2(0)=0$

therefore

The ordered pair is (0,0)

Part 2) we have (-2,?)

For x=-2

Substitute in the equation and solve for y

$y=2(-2)=-4$

therefore

The ordered pair is (-2,-4)

Part 3) we have (4,?)

For x=4

Substitute in the equation and solve for y

$y=2(4)=8$

therefore

The ordered pair is (4,8)

Marat540 [252]

They are all averages

mean=average 4+6=10, 10 divded by 2= 5, the mean is 5

median= middle number, 5 6 7, 6 is the median
mode= most repeated number, so 4,4,4,4,4,4,4,5.5,6 4 is the mode

In Mr. Harold's class there are 12 students. They each have 5 pencils. Some of the students, s, each lost 2 pencils. Now, the st

Katena32 [7]

The answer would be C. (12 x 5) - (s x 2) = 38.

This is because if there are 12 students with 5 pencils per student, we can say 12 x 5. Then, think of the phrase, two pencils lost per student. That would be 2s, or (s x 2). Since it’s lost, we would subtract that amount from 12 x 5.

<span>To acquire knowledge, thought is a fundamental necessity -It must be "thought about" before any new ideas can be formulated (e.g., a student who is learning English as a second language must be competent in his primary native language before he can "think" or understand new concepts in another language) -Initial emergence of language and thought are separate from each other, until about the age of 3 when a transition takes place in the child from the external to the internal -Children practice private speech (self-talk) to become more competent ---The use of private speech helps children to self-regulate through organizing, guiding, and controlling their behavior ---Private speech is responsible for all higher levels of mental functioning Noam Chomsky Language Acquisition -Language learning is innate -Chomsky believes that children are prewired to learn language and that infants have a language acquisition device (LAD) built-in neurologically so that they can intuitively understand grammar -There is a critical period when children find it easy to learn language Language development milestones: Infant (0-12 months) -Early vocalizations are spontaneous sounds of cooing (vowels) or crying -Then babbling sounds (phonemes) begin with sounds more like patterned speech with consonant-vowel strings ("da-da-da-da")</span>
