One institute mandates that for every 100 items scanned through the electronic checkout scanner at a retail​ store, no more than

2 should have an inaccurate price. A recent study of the accuracy of checkout scanners at the stores of a certain company showed​ that, of the 70 company stores​ investigated, 56 violated the​ institute's scanner accuracy standard. If 1 of the 70 company stores is randomly​ selected, what is the probability that that store does not violate the institute scanner accuracy​ standard?

Answer:

There is a 20% probability that the store selected does not violate the institute scanner accuracy​ standard

Step-by-step explanation:

70 company stores were investigared.

56 violated the​ institute's scanner accuracy standard.

70-56 = 14 did not violate the institute scanner accuracy​ standard.

If 1 of the 70 company stores is randomly​ selected, what is the probability that that store does not violate the institute scanner accuracy​ standard?

This is 14 divided by 70, so:

P = \frac{14}{70} = 0.2

There is a 20% probability that the store selected does not violate the institute scanner accuracy​ standard

Find each measurement indicated. Round your answers to the nearest tenth.
Crazy boy [7]

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

\frac{AB}{sin(C)} = \frac{AC}{sin(B)}

Thus:

\frac{AB}{sin(40)} = \frac{47}{sin(103)}

Multiply both sides by sin(40)

\frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40)

AB = \frac{47*Sin(40)}{sin(103)}

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)
