Hello!

The mean is 12

The data has a standard deviation of 4

Look and see how far away 18 is from 12 using 4

12 + 4 = 16

16 is one deviation

16 + 4 = 20

20 is two deviation

18 is right in the middle

The answer is C. 1.5 deviations

Hope this helps!

Which expression is equivalent to 144^3/2?
ira [324]

we are given

(144)^{\frac{3}{2} }

we can write it as

144=12 \times 12

144=12^2

we can replace it as

(144)^{\frac{3}{2} }=(12^2)^{\frac{3}{2} }

(144)^{\frac{3}{2} }=(12)^{2*\frac{3}{2} }

(144)^{\frac{3}{2} }=(12)^{3 }

(144)^{\frac{3}{2} }=1728...............Answer

katrin [286]

Answer:

Write a time equation, time = dist/speed

:

go time + return time = total time

d%2F16 + d%2F15 = 7.75 hrs

multiply equation by the least common multiple 240, cncel the denominators:

 

15d + 16d = 240(7.75)

31d = 1860

d = 1860/31

d = 60 km one way

total dist = 120 km

:

Check this, find the actual time each way

60/16 = 3.75 hrs

60/15 = 4 hrs

-----------------

total time 7.75 hrs
