2. What is Standard Deviation? Given the data 12 14 16 18 and 20 ounces, find the mean. Find the distance each value is to the mean. What are the
distances squared? What is the sum of the distances squared? What is the
mean of the distances squared? What is the square root? State the
standard deviation for this set of data.

3.76%

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

-2 is the right
