In order to find which one is greater, get them to a common denominator.
We can get them to a common denominator of 100.
This would be:
and
As you can see
.
is greater.
Hope this helps but I think the mean is the average of the numbers so to find the mean you add 9,8,12,6,and 10 together and then divide by 5 because that is the total numbers you have.So that means the mean is 9. The median is the middle number of the whole set to do that first put all the numbers in order.
6,8,9,10,12 , then find the middle number.In this the middle number is 9 because either side of 9 ha the same amount of numbers (2).There are 2 numbers on the left side of 9 and there are 2 numbers on the right side of 9.

Answer:
(c) 5.4°
Step-by-step explanation:
We can simply determine the difference between the angles of the vectors:
arctan(8/-5) -arctan(8/-4) = 122.005° -116.565° = 5.440°
The angle between the vectors is about 5.4°.

<em>Alternate solutions</em>
1) We could also determine the angle of their ratio.
u/v = (-5 +8i)/(-4 +8i) = (-5 +8i)(-4 -8i)/(4² +8²) = (84 +8i)/80 = 1.05 +0.1i
angle = arctan(0.1/1.05) = 5.440°
__
2) Tan(a-b) = (tan(a)+tan(b))/(1 -tan(a)(tan(b))
tan(∠u -∠v) = ((tan(∠u) -tan(∠v))/(1 +tan(∠u)tan(∠v))
= (-1.6 -(-2))/(1 +(-1.6)(-2)) = 0.4/4.2
∠u -∠v = arctan(2/21) = 5.440°
Answer:
x=-3 I promise that this is the Answer
Step-by-step explanation:
Answer:
im not sure but i think its 0.15
Step-by-step explanation:
the number of students are 40
there are 6 blonde girls out of those 40
6/40 simplified is 3/20
3/20 converted to decimal is 0.15
