Find the mean:

6 + 6 +10 + 8 + 10 +8 = 48

48 / 6 = 8

The mean is 8.

Now for each number, subtract the mean and square the result:

6 -8 = -2, -2^2 = 4

6 – 8 = -2, -2^2 = 4

10 – 8 = 2, 2^2 = 4

8 – 8 = 0, 0^2 = 0

10 – 8 = 2, 2^2 = 4

8 – 8 = 0, 0^2 = 0

Now find the mean of those results:

4 + 4 +4 +0 +4 + 0 = 16

16 / 6 = 2.6666

Now find the square root:

SQRT(2.666) = 1.63

The answer is A.

Find X, Y, Z,<br> (I believe X is 12?)
Serggg [28]

Answer:

x = 12    y = 24     z = 12\sqrt{3}

Step-by-step explanation:

you are correct.  x = 12

The dotted line has a length of 12 also

The dotted line is the shorter leg of the 30-60-90 triangle.

So, z = 12\sqrt{3} and y = 24

PLEASE HELP FAST!! I MIGHT GIVE BRAINLIEST TO FASTEST AND ACCURATE
goldenfox [79]

Answer:

1/6

Step-by-step explanation:

We want to find how long it takes for the bacteria to lose half its size. We can do this by taking one point of the bacteria and finding how long it takes to go to half its size. When t=0, 9300 * (1/64)^t = 9300 * 1 = 9300 as anything to the power of 0 is 1. Therefore, we can solve for t when the end result of the bacteria is 9300/2= 4650, making our equation

4650 = 9300 * (1/64)^t

divide both sides by 9300

1/2 = (1/64)^t

First, we can tell that 2^6 = 64*. Because of this, we can say that (1/2)^6 = 1^6/2^6 = 1/64, so (1/64)^(1/6) = 1/2. We know this because

(1/2)^6 = 64

take the 6th root of both sides

(1/2) = (64)^(1/6)

. This means that t=1/6, so the bacterial culture loses 1/2 of its size every 1/6 seconds

* if this is harder to figure out, e.g. 3 and 729, we can plug (log₃729) into a calculator
