option 1

2sqrt3/3

Step-by-step explanation:

Given in the question

csc(-4π/3)

we know that csc(x) = $\frac{1}{sin(x)}$ that means

$csc(\frac{-4\pi}{3})=\frac{1}{sin(\frac{-4\pi}{3} )}$

sin(-4π/3) = $\frac{\sqrt{3}}{2}$

so,

$csc(\frac{-4\pi}{3})=\frac{1}{\frac{\sqrt{3}}{2} }$

$\frac{1}{\sqrt{3}/2 }$ = $\frac{2}{\sqrt{3}}=\frac{2\sqrt{3}}{3}$

Theresa school has greater % of girls

Step-by-step explanation:

Given

Number of girl in the Anthony school = 260

Total student in Anthony school = 500

% of girl in the Anthony school = 260/500 * 100 = 52 %

Number of girl in the Theresa school = 360

Total student in Theresa school = 600

% of girl in the Theresa school = 360/600 * 100 = 60%

Theresa school has greater % of girls
