Suponha que uma variável assume os valores: 11 – 8 – 7 – a – 16 – 10 Determine a de modo que a média aritmética seja igual 11.

Elenna [48]

Answer:

a = 14

Step-by-step explanation:

The mean is the sum of the values divided by the number of values.

$\begin{array}{rcl}\text{Mean}&= &\dfrac{11 + 8 + 7 + a + 16 + 10}{6}\\\\\dfrac{52 + a}{6}& = & 11\\52 + a & = & 66\\a & = & 66 - 52\\& = & \mathbf{14}\\\end{array}$

Find the missing factor. Write your answer in<br> exponential form.<br> 6^-8 = blank 6^7

Keith_Richards [23]

Answer:

6^ (-15) = x

Step-by-step explanation:

6^-8 = blank 6^7

6^-8 = x* 6^7

Divide each side by 6^7

6^-8 / 6^7 = x 6^7 / 6^7

6^-8 / 6^7 = x

Since the bases are the same, we can subtract the exponents

6^ ( -8-7) = x

6^ (-15) = x
