About 2% of the population has a particular genetic mutation. 500 people are randomly selected.
S_A_V [24]

The standard deviation for the number of people with the genetic mutation in such groups is 3.1305.

<h3>Standard Deviation</h3>

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Let X be the number of people with genetic mutation is a group of 500,

The formula of standard deviation is given as

SD=\sqrt{n*p(1-p)} \\SD=\sqrt{500*0.02*0.98} \\SD=3.1305

The standard deviation of the given sample is 3.1305

(18) POINTS pLEASE HELP
JulijaS [17]

Answer:

(x-4)(x-3)

Step-by-step explanation:

x^{2} -7x+12\\

multiply 1 and 12= 12

find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

plug in these numbers for -7x

x^{2} -3x-4x+12

x(x-3)-4(x-3)

the bolded is the first binomial and the second binomial is in the parenthesis.

(x-4)(x-3)

I hope this helps!
