2(y-4)+5=3(y+2)
multiply the first bracket by 2
(2)(y)=2y
(2)(-4)=-8
multiply the second bracket by 3
(3)(y)=3y
(3)(2)=6
2y-8+5=3y+6
2y-3=3y+6
move 3y to the other side
sign changes from +3y to -3y
2y-3y-3=3y-3y+6
-y-3=6
move -3 to the other side
-y-3+3=6+3
-y=9
multiply both sides by -1 to get +y
(-1)(-y)=9(-1)
Answer:
y=-9
Answer:
Step-by-step explanation:
Given 
a)
we know that 
therefore 
on integrating we get
c=(1/6640)
b)
on doing the integration we get
=0.37349
c)
marginal density of X is
on doing integration we get
f(x)=(4x+3)/3320 ; 0<x<40
marginal density of Y is
on doing integration we get
d)
solve the above integration we get the answer
e)
solve the above integration we get the answer
f)
Two variables are said to be independent if there jointprobability density function is equal to the product of theirmarginal density functions.
we know f(x,y)
In the (c) bit we got f(x) and f(y)
f(x,y)cramster-equation-2006112927536330036287f(x).f(y)
therefore X and Y are not independent
Given a right triangle with the side lengths of legs = 9 and 13
For the required angle :
opposite side = 9
adjacent side = 13
so,

Answer:
33.6 seconds
Step-by-step explanation:
if he begins at 136 feet and wants to go to 42 feet, the distance is 94 feet
d = 94
r = 2.8
d = rt; solving this formula for 't':
t = d/r
t = 94/2.8
t = 33.6 seconds
Answer:
9 months
Step-by-step explanation:
Becase in 8 months he can pay 3200 but another month also need to pay ramining money
