Question

A quality control officer is randomly checking the weights of flour bags being filled by an automatic filling machine. Each bag is advertised as weighing 750 grams. A bag must weigh within 3.2 grams in order to be accepted. What is the range of rejected bags, x, for the bags of flour?
746.8 < x < 753.2

x < 750.0 and x > 753.2

750.0 < x < 753.2

x < 746.8 and x > 753.

Answer 1

I think the correct answer from the choices listed above is the last option. The range of the rejected bags, x, for the bags of flour. A bag of flour is said to  weigh within 3.2 grams in order to be accepted. Therefore, it should weigh within 746.8 to 753.2 grams. Outside that range is rejected.
