Argument
You have a total of 8 + 9 + 3 balls = 20
The first ball is 17/20 Probability that no ball drawn is red the first time
The Second ball is 16/19 Probability that no ball drawn is red the 2nd time
The third ball is 15/18 Probability that no ball drawn is red the 3rd time
Answer
Total Probability = 17/20 * 16/19 * 15/18 = 34/57
My calculator figures out fractions. You can do this just as easily with decimals.
0.85 * 0.8421 * 0.8333333 = 0.5964
34/57 = 0.5965 which is close enough.
If you have choices, choose the one that coincides with my answer. Otherwise use the decimal value.
Answer:
805.5 out of 900
Step-by-step explanation:
A test is out of 100 and because there are 9 tests: 9 x 100 which equals 900.
To get the average we add up each test mark and divide by the number of tests. The same can be applied here but reversed. So because there were 9 tests we can multiply 89.5 by 9 which gives us 805.5. Beverly scored 805.5 marks out of 900 which makes her average 89.5% for 9 tests.
10% is 8.35. 1% is 0.83 so 2% is 1.66. 8.35+1.66=10.01. 83.47+10.01=93.48. 93.48x12=1121.76. The bill will cost £1121.76.
Answer:
x = 12W
Step-by-step explanation:
Let x = power consumption of the LED bulbs.
Writing the ratio as a fraction;
Cross multiplying, we have;
x = 12
Therefore, the power consumption of the LED bulbs is 12W.
