Answer:
x = 3
y = 1
Step-by-step explanation:
(2x + 4y = 10) * 2 = (4x + 8y =20)
4x = 20 - 8y
Plug that into the other equation
(20 - 8y) - y = 11
-9y = -9
y = 1
Plug this value into one of the original equations
2x + 4(1) = 10
2x = 6
x = 3
Answer:
D
Step-by-step explanation:
The Median of the density is -6.
An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
It is clearly visible from the uniform density curve given in the question that the median of the population density is -6.
Because the area to the left and right of the density curve is the same.
Hence, the Median of density is -6.
