Answer:
B(2,4)
Step-by-step explanation:
A(-1,-9)
M(0.5,-2.5)
with M we can find x₂ and y₂
x = 0.5
x = x₁+x₂/2
0.5 = (-1 + x₂)/2
(x₂ -1)/2 = 0.5
x₂-1=0.5×2
x₂-1=1
x₂=2
for y₂
y= -2.5
y=(y₁+y₂)/2
y=(-9+y₂)/2
-2.5=(-9+y₂)/2
-9+y₂=-2.5×2
-9+y₂=-5
y₂=-5+9
y₂=4
.: coordinates are B(2,4).
Shifts the graph left 2, would look like
(x+2)^2
Answer:
Step-by-step explanation:
AB = a
AP = 2PQ = 2QB
AB = AP + PQ + QB
= AP + 
+
AB = 2AP
AP = 
-----(1)
And we know QB =
QB= AP/2 = 
---------(2)
Now midpoint of AP = × 
=
and midpoint of QB = × =
distance between these midpoints = -
=
E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
All except combine like terms. Since you only have 1 variable.
Hope this helps.
