Answer:
Domain should be Df = {x>-1}
Step-by-step explanation:
Insert the g(x) into the x of f(x) function. Then let the denominator of the fg(x) = 0 <em>(</em><em>u</em><em>n</em><em>d</em><em>e</em><em>f</em><em>i</em><em>n</em><em>e</em><em>d</em><em>)</em>. Find x.
Answer:
Therefore

Answer:
0.75
Step-by-step explanation:
P(A | B) = P(A and B) / P(B)
P(vanilla | sundae) = P(vanilla and sundae) / P(sundae)
P(vanilla | sundae) = 0.15 / 0.2
P(vanilla | sundae) = 0.75
Answer:
19/50
Step-by-step explanation:
If you put this in decimal form, it's 0.38.
All you have to do is convert the decimal to a reduced fraction, which is 19 over 50 (19/15).
Hope this helps you!
Answer:
Step-by-step explanation:
Matrix'is determinat:
X1 Y1
X2 Y2
D=(X1*Y2) - (X2*Y1)
D=(3X-4) - (-3*4)
D=0
Determinant of X
I 1 Y1
I 2 Y2
DX=( I 1 *Y2) - ( I 2*Y1)
DX= (14* -4) - (-14*4)
DX=0
Determinant of Y
X1 I 1
X2 I 2
DY= (X1 * I2) - (X2* I1)
DY=(3X-14) - (-3*14)
DY=0
The result of the variables are solved by:
X=DX/D.... Y=DY/D
X=0/0 Y=0/0
X=NaN Y=NaN
