2/3y + v = s solve for y
DanielleElmas [232]

Answer:

y = \frac{3s-3v}{2}

Step-by-step explanation:

Given

\frac{2}{3} y + v = s ( subtract v from both sides )

\frac{2}{3} y = s - v

Multiply through by 3 to clear the fraction

2y = 3s - 3v ( divide both sides by 2 )

y = \frac{3s-3v}{2}

In a normal distribution, what percent of the values lie above the mean?​
Leya [2.2K]

Mkey [24]

Answer: B) A = 750(1.04)ⁿ

<u>Step-by-step explanation:</u>

The formula for compounded annually is: A = P(1 + r)ⁿ   where

  • A (amount accrued) = <em>unknown</em>
  • P (amount invested) = $750
  • r (interest rate) = 4% -->(0.04)
  • t (time in years) = <em>unknown</em>

A = 750(1 + 0.04)ⁿ

  = 750(1.04)ⁿ

What does it mean to say that data has a strong negative correlation?
ra1l [238]

indica que as duas variáveis movem-se em direções opostas, e que a relação também fica mais forte quanto mais próxima de menos 1 a correlção ficar. Duas variáveis que estão perfeitamente correlacionadas positivamente (r=1) movem-se essencialmente em perfeita proporção na mesma direção, enquanto dois conjuntos que estão perfeitamente correlacionados negativamente movem-se em perfeita proporção em direções opostas.
