Consider the two number sets. Which set has the higher mean and what is that mean?
Otrada [13]

The mean is where you add all of the numbers in that set together, and divide it by the amount of numbers you have. E.g. For Set 1 - 10 + 15 + 20 + 25 + 30 + 50 = 150 ÷ 6 = 25

For Set 2 you just repeat the process:

1. Add the numbers in the set together, this gives you a total of 111

2. Then divide 111 by 5 as you have 5 numbers, giving you 22.2

Therefore set 1 has the higher mean :)

The answer is C, set 1, 25 :)

the speed that a tsunami can travel is modeled by the equation mc025-1.jpg , where s is the speed in kilometers per hour and d i
Flura [38]
The answer is a.0.32 km.

The speed that a tsunami can travel is modeled by the equation is s = 356√d.

It is given:
s = 200 km/h
d = ?

Now, let's substitute s in the equation and find d:
s = 356√d
200 = 356√d
√d = 200 ÷ 356
√d = 0.562

Now, let's square both sides of the equation:
(√d)² = (0.562)²
d = (0.562)² = 0.316 ≈ 0.32

Therefore, <span> the approximate depth (d) of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.</span>

using the coordinate plane shown below 1/3 point is plotted five units to the right of -4, for where should a four point be plan
Mrac [35]

we know that

the fourth point is plotted 5 units to the right of (-4,4)

so

the coordinate x of the fourth point is equal to

-4+5=1

the y-coordinate of the fourth point is the same y coordinate of (-4,4)

therefore

the coordinates of the fourth point is (1,4)
