Just number 1- please help! thank you!!

Step-by-step explanation:

For no.1

sloution,

for small

Area(A1)=?

now,

A = π r²

A=3.14*2.5^2

A=19.6

A1=19.6cm^2

For,big square

L=10cm

A2=?

now,

A=L^2

A=10^2

A=100

A2=100cm^2

For shaded area

A=A2-A1

A=100-19.6

A=80.4cm^2

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
