It is a good sampling method because it will show a varied amount of hours per person. Not everyone works at the same business so they will all be different. If he was to survey everyone in the high school then he would have an even MORE varied chart of hours each person works.

One earthquake has MMS magnitude 3.9. If a second earthquake has 120 times as much energy (earth movement) as the first, find th
Anna71 [15]

Answer:

The right answer is "5.9". A further solving is provided below.

Step-by-step explanation:

The given values are:

Initial Magnitude,

M₁ = 3.9

Let Second magnitude be M₂.

Now,

⇒  M_2-M_1=log(\frac{l_2}{l_1} )

On substituting the values, we get

⇒  M_2-3.9 = log (120)

On putting the value of "log 120", we get

⇒  M_2-3.9=2.079

On adding "3.9" both sides, we get

⇒  M_2-3.9+3.9=2.079+3.9

⇒                    M_2=5.9

How to find unknown side
Elan Coil [88]

Answer:

C = 10

Step-by-step explanation:

Find the last side of the triangle using the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

You have a and b already, a = 6, b = 8

6^{2} +8^{2} =c^{2} \\\\

solve this to get

64 + 36 = \sqrt{100}

C = 10

Apply the same to the other 2 triangles. C is your longest side!

Xelga [282]
8 units

Circumference = pi * 2 * radius
50.24 = 3.14 * 2 * radius
50.24 = 6.28 * radius
8 = radius
