Answer:

The number of watches made is 8

Step-by-step explanation:

SO the equation is C=15n+85 where C is the total cost and N is the amount of watches

1)plug in C

385=15n+85

2)move 85 to the other side so it would become -85

385=15n+85 → 385-85=15n → 100=15n

3)divide 15 from both sides

100/15=15n/15 → 25/3=n

since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)

Pedro has determined that the probability his shot will score in a lacrosse game is 0.30.
Igoryamba

For two shots Pedro has four outcomes:

<u>1 shot | 2 shot</u>

score | score

score | not score

not score | score

not score | not score

The probability Pedro's shot will score in a lacrosse game is 0.30 and the probability his shot will not score in a lacrosse game is 1-0.30=0.70. So you can count probabilities for all cases:

1. 0.3·0.3=0.09;

2. 0.3·0.7=0.21;

3. 0.7·0.3=0.21;

4. 0.7·0.7=0.49.

In total 0.09+0.21+0.21+0.49=1. The first outcomes is that what you need.

Answer: 0.09.
