Answer:
93.99
Step-by-step explanation:
sin rule is:
sin A ÷ a = sin B ÷ b = sin C ÷ c
A B C are angles
a b c are the lengths opposite to each angle
to find angle opposite to x:
180- (90+57) = 33°
180: sum of angles in a traingle
90: since its a right angle traingle
to find x:
sin 57 ÷ 41 = sin 33 ÷ x
rearrange:
x= (sin 33 x 41) ÷ sin 57
x= 93.99 (2 d.p/2 decimal places)

Answer:
(a) 5
(b) 3rd quartile
(c) 2nd quartile
Step-by-step explanation:
There are four quartiles in a box plot <em>(or box and whisker plot).</em>
The 1st is from 5 to 13
The 2nd is from 13 to 35
The 3rd is from 35 to 40
The 4th is from 40 to 48
<em />
(a) The lowest that this box plot goes is 5 <em>(between the 4 and 6)</em>
(b) 3rd quartile — we can see that the left and right borders are close together, meaning that the data values for this quartile are close together, and therefore concentrated
(c) 2nd quartile — we can see that this quartile is the widest, and therefore the data values are spread out
15/24
4 2/3=(4*3)+2/3=14/3
simply 15/24
15/3/24/3=5/8
refine
5/8*14/3
8 and 14 share a factor of 2
8/2=4
14/2=7
refine
5/4*7/3
5*7/4*3
35/12
convert to mixed number
35/12=2.11
2 11/12
the answer is 2 11/12
