Answer: Radius = 10 cm and Arc length = 5 cm
Step-by-step explanation:
The area of a sector with radius r and central angle
(In radian) is given by :-

Given : A sector of a circle has area
and central angle 0.5 radians.
Let r be the radius , then we have

Thus, radius = 10 cm
The length of arc is given by :-

Hence, the length of the arc = 5 cm

Step-by-step explanation:
we know each card is 1/3 of a mm as 81 times 1/3 is equal to 27 so simply divide your friends cards by 3 to find out the total
Answer:
a) "=T.INV(1-0.02,7)"
And we got 
b) "=T.INV(0.85,7)"
And we got 
Step-by-step explanation:
For this case we have a sample size of n=8, so we can find the degrees of freedom like this:

Part a
For this case we need a value who accumulates 0.02 of the area in the right of the t distribution with 7 degrees of freedom so we can use the following excel code:
"=T.INV(1-0.02,7)"
And we got 
Part b
For this case we need a value who accumulates 0.85 of the area in the left of the t distribution with 7 degrees of freedom so we can use the following excel code:
"=T.INV(0.85,7)"
And we got
