We know that
[area of a circle ]=pi*r²
diameter=4 in
r=4 in/2-----> 2 in
so
area=pi*2²-----> area of the circle=4*pi in²
the answer is
the area, in square inches, of the circle is <span>3.14 • 2²</span>

Factors of 8: 1, 2, 4, 8
Factors of 6: 1, 2, 3, 6
Factors of 10: 1, 2, 5, 10
- 1 3/5= -8/5 ( Multiply the denominator and whole number ) -1*5= -5 -3= -8
-8/5 ÷ -5/6
-8/5*-6/5 ( whenever dividing flip over the second fraction )
=48/25 ( whenever multiplying - negative and - negative = + positive number
48/25= 1 23/25
Answer :48/25 or 1 23/25
10 pieces of silverware laid in a row if 3 are identical spoons, 4 are identical forks, and 3 are identical knifes
The arrangement of 'm' objects on which 'n' objects are of same kind is 
Given: 10 pieces of silverware so its 10!
3 are identical spoons so its 3!
4 are identical forks so its 4!
and 3 are identical knifes so its 3!
Arrangements made =
= 4200
Answer:
0.86
Step-by-step explanation:
The z-score we need to make the comparison is given by
where
= the standard deviation established in the study
n = the sample size
and for the Normal distribution N(0,1) we want to find
<em>P(X > -1.0801)
</em>
By using a spreadsheet or the table attached, we find that
P(X > -1.0801) = 0.86
