Answer: 56%

 

Probably that it will rain and she goes + probably that it will be sunny and she goes

 

=     0.4 * 0.2     +           0.6*0.8

 

=          0.08      +              0.48

 

=   0.56

 

56% chance

SOLVE. integration of (1-v) /(1+v^2)
Marta_Voda [28]
I think you have to first separate the integral:1/(1+v^2) + v/(1+v^2),
so the integral of the first term is ArcTan (v) and for the integral of the second term i recommend you to do a change of variable:

y= 1+v^2
 so
 dy= 2v
 and
v= dy/2and then you substitute:v/(1+v^2) = (1/2)(dy/y)
and the integral is
 (1/2) (In y)finally you plug in the initial variables:

(1/2)(In [1+v^2])

so the total integral is:

ArcTan (y) + (1/2)(In [1+v^2])

THIS IS THE T H I R D TIME IVE POSTED THIS P L E A S E ANSWER
Goshia [24]

Find common denominators. 10 is the common denominator. Multiply 2 to numerator and denominator of -3/5

(-3/5)(2/2) = -6/10

x + 1/10 = -6/10

Isolate the x. Subtract 1/10 from both sides

x + 1/10 (-1/10) = -6/10 (-1/10)

x = -6/10 - 1/10

x = -7/10

-7/10 is your answer for x

hope this helps

How to solve x=6y-11 and 3x-2y=-1 by substitution
vagabundo [1.1K]
Substitute x into the second equation:
3(6y-11)-2y=-1
18y-33-2y=-1
16y=32
y=2
Then put the y value into the first equation to get x:
x=6(2)-11
x=1
There you go!

Answer Question Pls? I need Help!!
QveST [7]

Answer:

option D

Step-by-step explanation:

Take the two through which the lines passes.

Let it be ( -5 , 0) and ( 0 , -3)

Step 1 : Find slope, m

     Slope,m = \frac{y_2 -y_1}{x_2 - x_1}

                  = \frac{-3-0}{0--5} = \frac{-3}{5}

Step 2 : Find the equation

      (y - y_ 1) = m( x - x_1)\\\\( y - 0) = \frac{-3}{5} (x --5) \\\\y = -\frac{3}{5}( x  + 5 ) \\\\y = -\frac{3}{5}x  - 3
