The current mean is 3 (15/3)
adding 9 would make the mean 4 (24/6)
therefore the mean would increase by 1
Answer:
The change in elevation=2,400 feet
Step-by-step explanation:
The expression to determine the change in elevation after 6 minutes is a s follows;
D=S×T
where;
D=change in elevation in feet
S=speed/ descending rate
T=time
In our case;
D=unknown
S=400 feet/minute
T=6 minutes
replacing;
D=400×6=2,400 feet
The change in elevation=2,400 feet
Answer:
x=8
AC=148
Step-by-step explanation:
Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC
Knowing that AB=BC, we can sub the values given by the question:
AB = BC
9x+2 = 5x+34
9x-5x = 34-2
4x = 32
x = 8
Now that we know the value of x, we can find AC, since AC=AB+BC
AC = AB + BC
= 9x+2 + 5x+34
= 14x+36
= 14(8)+36
=112+36
=148
Hello,
Answer B
Is y=(5,t) a solution of -5x+y=-40
==>-5*5+t=-40
==>t=-40+15
==>t=-15
Now change the t to y (all is done to make you not to find the answer)
y=-15.
