Answer:
Mr. Li
Step-by-step explanation:
$447.75 is 4.5% of $9,950 - Mr. Li earns a 4.5% commission
$453.20 is 4.4% of $10300 - Ms. Brown earns a 4.4% commission
P(centre engine and left fail) = 0.004 x 0.007 = 0.000028
P(centre engine and right fail) = 0.004 x 0.007 = 0.000028
P(all three engines fail) = 0.004 x 0.007 x 0.007 = 0.000000196
P(plane will crash) = 0.000028 x 2 + 0.000000196 = 0.000056196
Answer:
Solution given:
now
f(x)+g(x)=
....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m
=
=now
opening bracket
=
So
answer is :
B. 
For a segment AB, the coordinates of the middle point C are:
xc=(xa+xb)/2,
yc=(ya+yb)/2.
Now, you know points A and C. Thus we get:
xb=2×xc-xa
yb=2×yc-ya
With numerical values:
xb=2×2-(-1)=4+1=5
yb=2×3-(-5)=6+5=11
Answer: B(5, 11)
I think it is a statistical question
