After 8 points are added to each score in a sample, the mean is found to be M= 40. What was the value for the original mean
MArishka [77]

Answer:

The value for the original mean = 32

Step-by-step explanation:

Here, we want to calculate the original value of the mean.

Let the number of samples be n

Mathematically;

mean = Total value/n

Now, we added 8 to each of values; total value added = 8 * n = 8n

Now, for the new mean of 40; we have

(Total value + 8n)/n = 40

Total value + 8n = 40n

Total value = 40n -8n

Total value = 32n

kindly recall from the beginning of the solution;

mean = Total value/n

mean = 32n/n

mean = 32

So the original value of the mean is 32

I need the answer please. Because I think i got mine wrong
Gekata [30.6K]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• a^{-m} ⇔ \frac{1}{a^{m} }

• a^{0} = 1

• a^{m} × a^{n} ⇔ a^{(m+n)}

Given

(a)

8^{-2} = \frac{1}{8^{2} }

(b)

\frac{1}{3^{-3} } = 3³

(c)

6^{-12} × 6^{8} × 6^{0}

= 6^{(-12+8)} × 1

= 6^{-4}

= \frac{1}{6^{4} }
