Answer:
3a, 13cm 5, 1:200
Step-by-step explanation:
In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm
then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200
I had difficulties with these as well. If you need extra help with the task 3 please pm me :)
Answer:
Data Set 1: 20
Data Set 2: 25
Step-by-step explanation:
Range = maximum value - minimum value
Range of Data Set 1:
Maximum value of data set 1 = 40
Minimum value of data set 1 = 20
Range of Data Set 1 = 40 - 20 = 20
Range of Data Set 2:
Maximum value of data set 2 = 60
Minimum value of data set 2 = 35
Range of Data Set 2 = 60 - 35 = 25
Answer:
1.)
The Venn diagram is in the attachment
2).
percentage of the population that owns only television== 16%
Step-by-step explanation:
The Venn diagram Is represented in the attached photo.
Let's call The total people x
X = people that own only television+ people that own only radio+ people that own both television and radio+ people that own neither the two.
X= (0.68x -y) +(y) +(0.72x-y)+(0.12x)
X= 0.68x-y+y+0.72x-y+0.12x
X= 1.52x-y
Y= 1.52x-x
Y= 0.52x
People that own both= 52%
people that own only television
= (0.68x -y)
= 0.68x-0.52x
= 0.16x
percentage of the population that owns only television= 0.16*100
percentage of the population that owns only television= 16%
9x es la respuesta porqe el -2xy se va por el
