To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20

Answer:
x=10
Step-by-step explanation:
Using Pythagoras theorem
H^2=O^2+A^2
26^2=24^2+A^2
676= 576+A^2
676-576= A^2
100= A^2
square root both sides
10= A
Therefore, x=10
Answer:
-15
Step-by-step explanation:
Sea-level can be seen as 0 on a number line. The Diver is going below the sea-level, so think of this as him going below the number zero, into the negatives. He is going down 15km, so -15km would represent the integer (whole number) that you're looking for.
The answer would be A. Radical sign 3.
Answer:
Tomas
Step-by-step explanation:
Let's use miles per hour
Maren:<em> 60 miles/hour</em> (It's given to us)
Safiya: 120 miles/3 hours
Let's divide both by three to get to miles/hour.
120/3=40
<em>40 miles/hour</em>
Tomas: 84 miles/1.2 hours
Let's divide both by 1.2 to get to miles/hour
84/1.2=70
<em>70 miles/hour</em>
Cam: 75 miles/1.5 hours
Let's divide both by 1.5 to get to miles/hour
75/1.5=50
<em>50 miles/hour</em>
After comparing all the speeds we can conclude that Tomas drove the fastest.
