Answer:
.Lower quartile = 3.5
Step-by-step explanation:
Rearranging the data from lowest to highest.
2, 3, 4, 5, 6, 7, 8, 9 , 10, 15
First finding the median to make it easier to find the lower quartile.
median : 6 and 7 but right now they're irrelevant so we don't honestly need to work that out.
The lower quartile would be 3 and 4
3+4= 7 divide by 2 = 3.5 is your lower quartile
Answer:
#adult tickets sold = 346
#student tickets sold = 812
Step-by-step explanation:
let 'x' = # adult tickets sold
let 'y' = # students tickets sold
System of Equations:
x + y = 1158
5x + y = 2542
I used the elimination method and multiplied the first equation by -1
-x - y = -1158
+<u> 5x + y = 2542</u>
4x = 1384
x = 346
346 + y = 1158
y = 812
(6+9i) is the answer I got.
For question 1:
Part i)
2.6 x 2.6 = 6.76 cm squared
No unit conversions needed
Part ii)
1.2 dm = 1.2 / 1000000 = 0.0000012 cm
0.0000012 x 0.0000012 = 0.00000000000144 cm squared
Question 2:
16.5dm = 16.5/ 1000 = 0.0165 m
0.0165 x 0.0165 = 0.00027225 m squared
I hope this has helped
