The ordered pair (0,0)(1,4)(2,16)(3,36)(4,64). write a rule that represents the function.
gayaneshka [121]
Let x represent first number in pair and y represent second number. We can see that x numbers are increasing by 1 on each next pair. y numbers are square of 0,2,4,6 and 8

Knowing all of that let "n" represent the position of the pair starting from 0!

than we can write that the rule is:
(n,(2n)^2)

HELP PLEASE!!!!!!!!!!!!!!!!!!!!!
rewona [7]

Answer:

Considerations:

$y=-(x) \left \{ {{\text{if } x0} \atop {{\text{if } x> 0\text{ then }y

$y=x\left \{ {{\text{if } x0}} \right. $

Also,

$-\frac{a}{b}=\frac{-a}{b}=\frac{a}{-b}, b\neq0         $

A positive number divided by a positive number results in a positive quotient, and its opposite is always negative.

The fraction $\frac{5}{-12} $  can be described as a positive number divided by a negative number, which always result in a negative quotient.

The fractions have same value, so Liam is correct.

Alex777 [14]

Complete question :

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.

Construct a confidence interval for the mean jump height of gray kangaroos.

Answer:

(271, 301)

Step-by-step explanation:

Given that:

Mean (x¯) = 286

Margin of Error = 15 inches

The confidence interval :

(Mean - Margin of Error), (mean + margin of error)

(286 - 15), (286 + 15)

(271, 301)

Hence confidence interval equals : (271, 301)
