First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
Answer:
Solution given:
sin y = -4/5
p/h=4/5
p=4
h=5
b=√{5²-4²)=3
cos y = b/h=-3/5
again
cos x=12/13
b/h=12/13
b=12
h=13
p=√(13²-12²)=5
sin x=p/h=5/13
now
sin[x-y]=sinxcosy-cosxsiny
=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.
Answer:
see the explanation
Step-by-step explanation:
we know that
In a Rhombus opposite angles are congruent and consecutive angles are supplementary
The diagonals are perpendicular and bisect the angles
so
step 1
Find the measure of angle 4
we know that
--->by the diagonals bisect the angles
step 2
Find the measure of angle 1
we know that
----> by opposite angles are congruent
step 3
Find the measure of angle 2
we know that
----> by the diagonals bisect the angles
so
step 4
Find the measure of angle 3
we know that
----> by the diagonals are perpendicular
step 5
Find the measure of angle 5
we know that
----> by complementary angles
step 6
Find the measure of angle 6
we know that
----> by the diagonals bisect the angles
