Step-by-step explanation:
Share 20pounds in the ratio 2:3
Total ratio=2+3=5
2/5×20=8
20-8=12
Sharing 20pounds in that ratio gives 8pounds:12pounds
Share 15cm in the ratio 1:3
Total ratio=1+4=4
¼×15=3.75
15-3.75=11.25
Sharing 15cm in that ratio gives 3.75:11.25
Answer:
A
Step-by-step explanation:
to find (g ￮ f)(3) , evaluate f(3) and substitute the value obtained into g(x)
f(3) = | 3 + 2 | = 5 , then
g(5) = - 5² = - 25
Answer:
attached below
Step-by-step explanation:
Attached below is a detailed solution to your problem above
a) show that the maximum likelihood estimator of Ï2 is Xi and Yi.
attached below is the detailed solution
Y = -2x + 6....so we sub in -2x + 6 for y in the other equation
3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3
now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0
so ur solution is : (3,0)
Answer:
