Which value or in the solution set of the inequality − 2/3 x + 13 ≥ − 1
Svetach [21]

Answer:

x\leq21

Step-by-step explanation:

(-2/3)x+13≥ -1

    (-2/3)x≥ -14 (I subtracted by 13 on both sides)

             x\leq-14*(-3/2) (I divided by -2/3 on both sides)

             x\leq21

About 5% of the population has a particular genetic mutation. 300 people are randomly selected.
xz_007 [3.2K]

The standard deviation for the number of people with the genetic mutation is 3.77

<h3>How to determine the standard deviation?</h3>

The given parameters are:

Sample size, n = 300

Proportion that has the particular genetic mutation, p = 5%

The standard deviation for the number of people with the genetic mutation is calculated as:

Standard deviation = √np(1 - p)

Substitute the known values in the above equation

Standard deviation = √300 * 5% * (1 - 5%)

Evaluate the product

Standard deviation = √14.25

Evaluate the exponent

Standard deviation = 3.77

Hence, the standard deviation for the number of people with the genetic mutation is 3.77
