The mean is 7.5 you add up all the numbers and then divide by the amount of numbers there is
Answer:
24-3=21 , 36-4=32 , 3+4=7 , 7 x 5 , which equals 35
Step-by-step explanation:
C. 40
30x30=900
40x40=1600
total of 2500 take the square root and your left with 50 so everything balances out
Step-by-step explanation:
Ermm you're gonna have to write the entire question here for assistance
Each petal of the region

is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length

, which implies the segment is subtended by an angle of

. This means the area of the segment is


This means the area of one petal is

, and the area of

is four times this, or

.
Meanwhile, the area of

is simply the area of the square minus the area of

, or

.
So



(provided these regions are indeed disjoint; it's hard to tell from the picture)
