Firstly, arrange the data.
19 23 26 28 28 30 31 35 38 40 43 46
a) 5 number summary
-min value = 19
- Q1= (26+28/2) = 27
- Q2/ Median = (30+31/2)= 30.5
- Q3= (38+40/2)= 39
- Max value- 46
b) range= max value-min value
∴46-19= 21
c)interquartile range = Q3-Q1
= 39-27
=12
y=(-2/3)x+11/3
Step-by-step explanation:
3y=-2x-5
y=(-2/3)x-5/3
y-3=(-2/3)(x-1)
y-3=(-2/3)x+2/3
y-9/3=(-2/3)x+2/3
y=(-2/3)x+11/3
Answer:-6
Step-by-step explanation:
Open the brackets
-x is the same as -1x
(2
x -
)(3
)
- The bases will be multiplied while the powers will be multipled
-2
x 3
- In the law of indices(multiplication), provided the bases are equal,they are to be added.
-6 
= -6
