Ten thousand marbles were produced on a production line. the first 100 marbles off the line were taken and tested for roundness. does this sampling result in a simple random sample?

1. minimum

2. 6400

3. eight

hope this !

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
