Answer:
240 more girls
Step-by-step explanation:
210 + 160 = 370
100 + 30 = 130
370 - 130 = 240
C is your correct answer. Good luck.
Answer:
m=1/300 du
Step-by-step explanation:
we have that m=∫∫rho(x,y)dA for this we must find the limits of integration (according to the graph1)
On the x axis: if y=2x and x+2y=1 then y=2x and y=(1-x)/2 ⇒ 2x=(1-x)/2 ⇒ 4x=1-x ⇒ 5x=1 ⇒ x=1/5; on the y axis y=0 and y=1/2
m=∫∫rho(x,y)dA (view the graph 2)
1/4 is 25 percent so it is still 40.00
