Answer:
mean =503.75
median=400
mode=400
range=691
Step-by-step explanation:
mean= 211+351+359+400+400+659+748+902=4030/8= 503.75
range= highest number -lowest number = 902-211=691
median= 400+400 =800/2= 400
So you need to find a number that goes into both of these numbers:
3 goes into both, so divide both by 3
27/3 = 9
42/3 = 14
so your answer is 9/14
Answer:
Step-by-step explanation:
x³-6x²+11x-6
put x=1
1³-6×1²+11×1-6=1-6=11-6=0
by synthetic division
1| 1 -6 11 -6
| 1 -5 6
|----------------
| 1 -5 6 |0
x²-5x+6=0
x²-2x-3x+6=0
x(x-2)-3(x-2)=0
(x-2)(x-3)=0
x=1
x-1=0
so x³-6x²+11x-6=(x-1)(x-2)(x-3)
Answer:
Ihorangi uses 7.65 litres of petrol to and from work
Step-by-step explanation:
If the car Ihorangi drives consumes 7.5 L/100 km
Then for 1 km journey, the car will consume 7.5/100 L
= 0.075 L
If Ihorangi travels 51 km to work and 51 km from work
Therefore Ihorangi travel (51 + 51) km daily to and from work
= 102 km daily
The fuel he consumes daily is 102*0.075 L
= 7.65 L
Y=x+70
