Answer:

The correct answer is C. (8x+3)(8x+3)

Step-by-step explanation:

In order to obtain the correct answer we have to analyze the terms of the polynomial. Notice that the first term has 64 as coefficient, and 64=8*8 and the third term is 9, and 9=3*3. Those facts suggest that the factorization can be done in term of a square binomial. This assumption is confirmed noticing that 48=2*8*3. Therefore, 64x^2+48x+9 = (8x+3)(8x+3).

The answer can be checked expanding the product (8x+3)(8x+3).

.) A population of values has a normal distribution with μ=27.5 and σ=71.5. You intend to draw a random sample of size n=180.

Paraphin [41]

Answer: a) 27.5, b) 5.33.

Step-by-step explanation:

Since we have given that

$\mu =27.5\\\\\sigma =71.5$

and n = 180

We need to calculate the sample mean and sample standard deviation.

So, the mean of the distribution of sample means is

$\mu = \mu_x=27.5$

The standard deviation of the distribution of sample means is

$s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{71.5}{\sqrt{180}}=5.329=5.33$

Hence, a) 27.5, b) 5.33.

25.3 = s + 6.2 s= unknown

Answer:

s = 19.1

Step-by-step explanation:

Simplifying

25.3 = s + 6.2

Solving

25.3 = 6.2 + s

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-1s' to each side of the equation.

25.3 + -1s = 6.2 + s + -1s

Combine like terms: s + -1s = 0

25.3 + -1s = 6.2 + 0

25.3 + -1s = 6.2

Add '-25.3' to each side of the equation.

25.3 + -25.3 + -1s = 6.2 + -25.3

Combine like terms: 25.3 + -25.3 = 0.0

0.0 + -1s = 6.2 + -25.3

-1s = 6.2 + -25.3

Combine like terms: 6.2 + -25.3 = -19.1

-1s = -19.1

Divide each side by '-1'.

s = 19.1

Simplifying

s = 19.1
