Answer:
1 is biased, 2 isn't, 3 is biased, 4 isnt
Step-by-step explanation:
If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.
V=1024 pi m^3 and v=250 pi m^3
the similarity ratio of the smaller to larger similar cones is
k= V/v=1024 pi m^3/250 pi m^3= 4.096
the great cone is 4.096 times of the small cone (in volume)
The Answer is B. I hope this helped.
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
Hope this helps!!
Compounded depreciation formula:
A = P(1 - r)ⁿ , where P = original price, r= rate of depreciation, n = number of years and A = actual value (after depreciation):
A= $8000(1 - 11%)⁵ = 8000(0.89)⁵ = 4,467.24 ≈$4,467
