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

1/2=3/6
4/6=4/6
4/6>3/6

Answer:
If the roots of any equation are equal then it means that their Discriminant = 0
So, b²-4ac = 0
We have given the equation 2x² + kx + 2, where,
a = 2
b = k (we have to find the value)
c = 2
Then, b²-4ac=0
b² - 4(2)(2) = 0
b² - 16 = 0
b² = 16
√16 = 4
Hence the vue of k is 4.
