Answer:45
Step-by-step explanation:
Any number raised to the 0 power equals 1. So, 5 x 10^0 is the the same as (5x1)x(9x1)
5x1=5 9x1=9 5x9=45
Answer:
15/32
3/4 x 5/8 = 15/32 in fraction form.

0.03.
Step-by-step explanation:
Answer:
Step-by-step explanation:
levels of organic pollutants with 99.7% accuracy
levels of volatile solvents with 99.92% accuracy
levels of chlorinated compounds with 89.7% accuracy
samples:
60% contaminated with organic pollutants
27% contaminated with volatile solvents
13% contaminated with traces of chlorinated compounds
a) probability that the test will signal?
P = 0.997*0.6 + 0.9992*0.27 + 0.897*0.13 = 0.5982
+ 0.269784 + 0.11661 = 0.984594 = 98.45%
b) If the test signals, the probability that chlorinated compounds are present?
P = 0.897*0.13/0.984594 = 0.11661/0.984594 = 0.1184346035 = 11.84%
Answer:
2, 3, 4, 5, 6, 7 or 8.
Step-by-step explanation:
We know that the sum of two sides on a triangle should ALWAYS be greater than the third side. Then we have:
5-4 < x < 5 + 4
1 < x < 9
Therefore, the lenght of the third side could be any number between 1 and 9. If the lenght of the third side is an integrer, then the lenght could be:
2, 3, 4, 5, 6, 7 or 8.
