Answer:
dunt know just doing it for the points
Step-by-step explanation:
Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!
Answer:
2 a. x= -2, x=10 2 b. x= -7, x=7
Step-by-step explanation:
move the -6 to the left to get
-7 x lx-4l = -42
divide both sides of the equation by -7
lx-4l = 6
separate into
x-4=6 and x-4= -6
solve by adding 4 to both sides
then on the other one add 4 to both sides
2b you do the same steps just different numbers
The true statements are:
A. Tree A's heights are less spread out than tree B's heights and
B. Tree A has lower average height than tree B
Explanation:
Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.
The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.
