expand 0.55\pm 2sqrt((0.55(1-0.55))/(50))

expand

0.55 \pm 2 \frac{0.55 ( 1 - 0.55 )}{50}

2 \cdot 0.55 \cdot \frac{0.49749 \dots}{5 2} \pm

Solution steps

0.55 \pm 2 \frac{0.55 ( 1 - 0.55 )}{50}

Apply radical rule:

\frac{a}{b} = \frac{a}{b}

\frac{0.55 ( 1 - 0.55 )}{50} = \frac{0.55 ( 1 - 0.55 )}{50}

= 2 \cdot 0.55 \cdot \frac{0.55 ( 1 - 0.55 )}{50} \pm

0.55 (1 - 0.55) = 0.49749 \dots

= 0.55 \pm 2 \cdot \frac{0.49749 \dots}{50}

50 = 52

= 0.55 \pm 2 \cdot \frac{0.49749 \dots}{5 2}

x^{2} e^{- 2 y}

π r^{2} \cdot 3 π r^{2}

\frac{1}{3} π (30)^{2} (30)

e^{- x} \frac{( 1 - cos ( x ) )}{x}

3.33 \cdot 1 0^{- 6}
