Answer:
The value of x is -5/3.
The value of 1/3 - x is 2.
Step-by-step explanation:
-3( x+2)-5=x-(6+x) Distribute
-3x + -6 - 5 = x - 6 - x Combine llike terms
-3x + -11 = -6 <em><u>POSITIVE AND NEGATIVE IS NEGATIVE</u></em>
-3x -11 = -6 Add 11 on both sides
-3x = 5 Isolate the variable by dividing -3 on both sides
x = -5/3
1/3 - x
= 1/3 - -5/3 <u><em> </em></u><u><em>NEGATIVE AND NEGATIVE IS POSITIVE</em></u>
= 1/3 + 5/3
= 6/3
<em>= 2</em>
<em>You must isolate the variable in order to solve equations with variables.

<em>Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on </em><u><em>ONLY </em></u><em>one side of the equation.

To solve for b
a+2b=c
subtract a from both sides
2b=c-a
divide both sides by 2
b=(c-a)/2
Answer:
36
Step-by-step explanation:
The variance of one human is σ² = 36 days. Each gestation time for each human of the sample is independant of the other.
Both variance and mean of the sum of identically distributed indipendant random variables is equivalent to the product of the variance/mean of one element of the sample by the sample length.
Therefore, if we take the sum n of random variables with variance 36, then the variance of the sum will be 36*n. The sampling distribution is obtained from the sum by dividing by n. If we divide by a number, then the variance will be divided by its square. So the variance of the sampling distribution is 36*n/n² = 36/n, and the standard deviation is 6/√n days.
If we want the sampling distribution to have standard deviation equal to 1 day, then we need n such that
This shows that the sample length should be 36.
