the probability of picking rotten apple in a box is 1/100 .if there are 6 boxes containing 1200 apples each how many rotten appl

bulgar [2K]

<h3>Answer:</h3>

$\huge{\boxed{72}}$

<h3>Explanation:</h3>

First, find the total number of apples. $6*1200=7200$

Now, multiply this by the probability of picking a rotten apple, which is $\frac{1}{100}$ . This is also the same as dividing by $100$ , or moving the decimal point two places to the left. $7200*\frac{1}{100}=72$

This means that based on the probability given, $72$ rotten apples will be picked.

The measure of each interior angle of a regular polygon is 150 how many sides does the polygon have?

Dmitry [639]

The exterior and an interior angles always add up to 180 degrees.
180-150=One exterior angle
180-150=30
We know that all of the exterior angles add up to 360
360/30= the number of sides
360/30=12
The shape has 12 sides.
