Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
Answer:
263.76 m^3
Step-by-step explanation:
Using 3.14 as pi
pi * radius^2 * height / 3
3.14 * 6^2 * 7 / 3
3.14 * 36 * 7 /3
3.14 * 252 /3
3.14 * 84
263.76
The correct answers are B and D.
A is false because, even though it's true that 4 points are not necessarily on the same line, it is not required that they are collinear in order for them to be coplanar.
B is true: two points always lie on the same line (and thus also in infinite same planes), but four points are not always coplanar
C is false. As a counterexample pick the four points (0,0, 0), (1, 0, 0), (0, 1, 0), (0, 0, 1).
D is true: two points are always on the same line, three points always lie in a common plane, but 4 points are not necessarily coplanar.
Y=1/2x-2
Since y is 2 less than half of x, you subtract to from 1/2x to equal y.
The answer is 7/5 th. You can add fractions without first having a common denominator so you would change the 8's by multiplying it by 5 to get 40 and you would multiply the 5 by 8 to get 40 as well. And the rule whatever you do to the bottom you have to do to the top so whatever you multiplied 8 by do the same for the numerator and whatever you multiplied 5 by you do the same for the numerator. So your new equation would be (75/40+16/40)+(-35/40). you would then add the numerator's across to get 56 and the denominator would stay the same so the answer is 56/40. But you have to now simplify 56/40 down to 14/10 and then once more to 7/5 which is the final answer.
