Answer:

x is 10.

Step-by-step explanation:

3x + 12 = 42

<em>Subtract 12 from both sides</em>

3x = 42 - 12

<em>Subtract 12 from 42 to get 30</em>

3x = 30

<em>Divide both sides by 3</em>

x = 30/3

<em>Divide 30 by 3 to get 10</em>

x = 10

About 10% of the population has a particular genetic mutation. 700 people are randomly selected. Find the standard deviation for
Oduvanchick [21]

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

Solve this system of equations by graphing. First graph the equations, and then type the solution.
Yakvenalex [24]

Answer:

The answer is below

Step-by-step explanation:

Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2

Solution:

The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.

After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:

The solution = (-4, -6)
