Answer:
We need the picture.
Step-by-step explanation:
Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.
Answer:
The ship S is at 10.05 km to coastguard P, and 12.70 km to coastguard Q.
Step-by-step explanation:
Let the distance of the ship to coastguard P be represented by x, and its distance to coastguard Q be represented by y.
But,
<P = 048°
<Q = 
- 
= 0
Sum of angles in a triangle = 
<P + <Q + <S =
048° + 0 + <S =
+ <S =
<S = -
= 
<S =
Applying the Sine rule,
= 
= 
=
= 
= 
⇒ y = 
= 12.703
y = 12.70 km
=
=
=
⇒ x = 
= 10.0475
x = 10.05 km
Thus,
the ship S is at a distance of 10.05 km to coastguard P, and 12.70 km to coastguard Q.
-5= -5x-10
Plus 10 from both sides
5=-5x
X = -1
Distribute 2/5 and 3/5 into the ():
2/5(a+b)+3/5(a+c)
2/5 a+ 2/5 b+3/5 a+ 3/5 c
combine the like terms:
2/5 a+3/5 a= 5/5 a --> 1a --> a
new simplified equation:
a+2/5 b+3/5 c
Answer:
C
