Answer:
Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
<u>Two different colored marbles are:</u>
- blue, then red or red, then blue
<u>Find the probability of each case:</u>
- P(b, r) = 3/8*5/7 = 15/56
- P(r, b) = 5/8*3/7 = 15/56
<u>Required probability is:</u>
- P(different color) = 15/56*2 = 15/28
30 square feet.
2 x 5 is 10. 4 x 2 is 8. 10 + 8 = 18. If you look at where the two is at the top and make a line above it’s in half. So it would add 2 more to the four in the second box. So 6 x 2 = 12. And 18 + 12= 30.
Given:
Actual: 9.0 lbs with standard deviation of 0.35 lbs
sample: 8.2 lbs
standard deviation means that the fish caught should be within the range of 8.65 and 9.35
9.00 + 0.35 = 9.35 lbs
9.00 - 0.35 = 8.65 lbs
The sample that had an average weight of 8.2 lbs is not a representative of the population because its weight goes beyond the standard deviation.
The coefficient of n-9 is 1 because is the number in front of the variable n
