D = r * t is the formula that will be used to find the distance traveled.
Serenity: d = 17 * 2
Serenity = 34 miles

Mystic: d = 20 * 2
Mystic = 40 miles

34 + 40 = 74 miles
They are 74 miles apart after 2 hours

What is the mean of this data set? {6, 11, 5, 2, 7} Enter your answer as a decimal in the box.
Elenna [48]

Answer:

The mean is 6.2.

Step-by-step explanation:

The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.

So:

Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31

You find the average by dividing the sum of the terms (31) by the number of terms (5).

31/5 = 6.2

The mean is 6.2.

I hope this helped! :)

What is 12a equal to if 4a plus 6b = 10 and 2a-4b=12?
hram777 [196]
12a=x
4a+6b=10
2a+3b=5
2a-4b=12
a-2b=6
2a+3b+1=a-2b
a+5b+1=0
a=-1-5b

2(-1-5b)+3b=5
-2-10b+3b=5
-2-7b=5
-7b=7
7b=-7
b=-1

-1-5*-1=a
-1+5=a
4=a

4*12=48
12a=48

Hope this helps :)
