Answer:
its hard to do this without a graph to draw on for you but see explanation
Step-by-step explanation:
from each point count how many units it is from the mirror line and then count that many in the opposite direction. for example, the top left point is 3 away from the mirror line from the left so count 3 units to the right of the mirror line and that is where that point will be.
It says that mean of six nos is 4.7
So, that means ( no pun intended), the average of six numbers give a value of 4.7
the same goes for the average of the other four numbers=6.5
If we're talking about the mean ( average) of all the ten numbers , we usually would need the ten numbers ( their values and their frequency) , but since its already given as mean itself , we could just add up the values.
4.7+6.5=11.2
10 : 18 2 into 10 is 5, 2 into 18 is 9.
5 : 9.
You can also choose to multiply 10 : 18 by 2.
2*10 : 2*18
20 : 36.
Therefore 5 : 9 and 20 : 36 are two ratios that are equivalent to 10 : 18.
Answer:

Answer:
Step-by-step explanation:
Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.
From the above we find that population proportion is 0.03 and observed sample proportion is 0.04
So option a) is wrong
b) Correct
c) correct
d) Wrong
e) wrong
