Answer:

  D.  2x² +74x +644

Step-by-step explanation:

The first number can be written as (x +23).

The second number can be written as 2(x+23)-18 = (2x +28).

The product of these numbers can be found using the distributive property:

  P(x) = (x +23)(2x +28) = x(2x +28) +23(2x +28)

  = 2x² +28x +46x +644 . . . . . . . already you know the correct answer choice

  P(x) = 2x² +74x +644

Consider the following binomial experiment: A newspaper publisher claims that 52% of the people in a certain community read his
AURORKA [14]

Answer:

SD = 8.4932

Step-by-step explanation:

Given

Sample\ Size (n) = 289

proportion, p= 52\%

Required

Determine the standard deviation (SD)

The standard deviation of a binomial distribution is calculated as thus:

SD = \sqrt{np(1-p)}

Substitute values for n and p

SD = \sqrt{289 * 52\% * (1-52\%)}

Convert to decimals

SD = \sqrt{289 * 0.52 * (1-0.52)}

SD = \sqrt{289 * 0.52 * 0.48}

SD = \sqrt{72.1344}

SD = 8.49319727782

SD = 8.4932 --- <em>approximated</em>

<em>Hence, the calculated standard deviation is approximately 8.4932</em>
