Here are ten numbers

Solution,

Given data=3, 7 , 2 , 4, 7, 5, 7, 1, 8, 8

a.Mode= 7 because it has more frequency in comparison to others.

b.Arranging the data in ascending order:

: 1,2,3,4,5,7,7,7,8,8

N(total number of items)=10

Median=(N+1/2)th item

= (10+1/2)th item

= (11/2)th item

= 5.5th item

Again,

5th item+6th item/2

= 5+7/2

=12/2

= 6

c. summation FX=52

N=10

Mean= summationfx/N

=52/10

=5.2

D. Range= highest score- lowest score

= 8-1

=7

Hope it helps

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
