Answer:

3^16

Step-by-step explanation:

12^8 * 9^12

Rewrite 12 as 3*4 and 9 as 3*3

(3*4)^8 * (3*3)^12

We know that (ab)^c = a^c * b^c

3^8 4^8 3^12 3^12

We can write 4 as 2^2

3^8 2^2^8 3^12 3^12

We know a^b^c = a^(b*c)

3^8 2^(2*8) 3^12 3^12

3^8 2^(16) 3^12 3^12

We also know that a^b *a^c *a^d = a^(b+c+d)

2^(16) 3^8 3^12 3^12

2^(16) 3^(8+12+12)

2^16 3^(32)

But we need 6 ^16 so we will need a 3^16 3^32 = 3^16 * ^16 (16+16=32)

2^16 *3^16 *3^16

Remember a^b*c^b = (ac)^b

(2*3)^16 3^16

6^16 3^16

The question is incomplete. The complete question is :

The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed.

Required:

a. Find the mean μ.

b. Find the standard deviation σ.

c. The standard deviation σ.

Solution :

a). Percentage of the US adults who drinks coffee daily = 62%

Therefore, the mean, μ = 0.62

b). We know, p = μ = 0.62

And n = 225

Therefore, the standard deviation is given by :

$\sigma=\sqrt{\frac{p\times (1-p)}{n}}$

$=\sqrt{\frac{0.62\times (1-0.62)}{225}}$

$=\sqrt{\frac{0.62\times 0.38}{225}}$

$=0.0324$

c). Standard deviation, σ = 0.0324

139 = x + (2x + 10)
139 = 3x + 10
129 = 3x
/3 /3
43 = x

Therefore
