Answer:
the mean is 8 and the absolute deviation is 1.5
Step-by-step explanation:
to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!
Answer:
5400
Step-by-step explanation:
so 90% of 850 is 765 (0.90x850)
765 is 10 years
so 1 year is 765/10 = 76.5 per year. So 76.5x59 = 4,513.5 add the initial ammount and you got 5,363.5 in the nearest hundredth you get 5400
Probability of green die being even: 3/6, which simplifies to 1/2 (2, 4, 6 are even and 1, 3, 5 are odd)
Probability of blue die being even: 3/6, which simplifies to 1/2.
Compound probability:
1/2* 1/2= 1/4
Final answer: 1/4
Answer is 2( x + 2 )^2 - 5 I think
<u>Answer:</u>
The correct answer option is 'Every tenth student in the main hallway between class.'
<u>Step-by-step explanation:</u>
Every tenth student in the main hallway between class would best represent the sample population since majority of the students transit this hallway unlike the rest of the options.
For instance, polling every tenth student in the library at lunch would result in the favor of views of students who frequently visit the library and polling every tenth student in the student section at the school football game would go in favor of those who prefer sports.
