Answer:

Well I don’t know which one your using but I’m gonna list the two most common ones.

For the π sign The answer is

50.27km^2

For repalcing π with 3.14, the answer is

50.24km^2

Step-by-step explanation:

SO circumference forumla is Diameter*π

Well we have 8π as the circumference

So basically 8π=diameter*π

Since π is the same 8 is the diameter

Area = πr^2

8/2=4 which is the radius

4^2=16

16π now since the answer asks for final answer rounded to the first 2 decimal places.

Step-by-step explanation:

-30+9x=-0.5 |x-1| -2

from the graph, we can see that both curves intersect at (3,-3)⇒x=3

put x=3 in LHS&RHS

⇒LHS=-30+9(3)=-3

RHS=-0.5 |3-1|-2=

-1/2×2-2=-1-2=-3

so the answer will be 3..

hope it helps..

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

Arrange the value into the ascending order:

$62, 88, 89, 90, 92, 95, 96, 98, 100, 100$

Calculating the Range:

$= Greatest - Lowest\\\\= 100 - 62\\\\ = 38$

Outlier = This might be the value "far" from other data values= 62

The range of scores would be, sans outlier,

$88, 89, 90, 92, 95, 96, 98, 100, 100$

Calculating the range without outlier $= 100 - 88 = 12$

Inter Quartile Range $= Q_3 - Q_1$

$IQR = 98 - 89 = 11$

Calculating the IQR without outlier $= 99 - 89.5 = 9.5$

Therefore,

Option a is "True".

Option b is "True".

Option c is "True".

Option d is "False".

Option e is "False".

Option f is "True".
