Answer: 7.94

Step-by-step explanation:

The formula to calculate the standard deviation for binomial distribution :-

\sigma=\sqrt{np(1-p)}, where n is the number total of trials and p is the probability of getting success in each trial.

Given : The probability of the population has a particular genetic mutation=0.1

If 700 people are randomly selected, then the standard deviation for the number of people with the genetic mutation in such groups of 700 will be :-

\sigma=\sqrt{700\times0.1(1-0.1)}\\\\\Rightarrow\sigma=\sqrt{63}\\\\\Rightarrow\sigma=7.9372539331\approx7.94

Hence, the standard deviation for the number of people with the genetic mutation in such groups of 700 = 7.94

What is the answer to 1/7(x+3/4)=1/8
ivolga24 [154]

Answer:

<h3>x = 1/8</h3>

Step-by-step explanation:

1/7(x+3/4) = 1/8

Multiply 1/7 with x and 3/4

1/7x + 3/28 = 1/8

Multiply everything by 7, so x is a whole number

x + 21/28 = 7/8

Convert 21/28 into a similar like denominator to 7/8

x + 6/8 = 7/8

x = 7/8 -6/8

x = 1/8

Help me solve this please ill give good rating...
blagie [28]

Answer: For the first part, her total savings would be $88, and for the second part, (let's pretend s = the total savings) the equation would be s = 40 + w x 6.

Step-by-step explanation: As for the first part, we would need to multiply her money per week times the amount of weeks she works. We can do this by simply multiplying the amount she makes (6) by the amount of weeks she works (8), resulting in 48, but we still have to add that number to the amount she already has, or 40, making $88 in total, as for the second part, this does a great job of explaining the reasoning behind that as well. Hope this answered your question!
