Answer:
4 times 5 = 20, and 20 is... well.. 20
Step-by-step explanation:
When a number has another number in parentheses by it, it means you multiply the numbers together. So 4(5) is the same as 4 times 5, which equals 20
Median:(13+43)/2 so it is 28
The mean:(11+13+43+47)/4 = 28.5
Y = 1/csc(t) = 1/sin(t) = 1/x
A Cartesian equation of the curve is
y = 1/x . . . . . -1 ≤ x ≤ 1
