Answer:
29
Step-by-step explanation:
(5+1)^2-(12+3^2)/3 Add 5 and 1 = 6.
6^2-12+3^2/3 Calculate 6 to the power of 2 = 36.
36-12+3^2/3 Calculate 3 to the power of 2 = 9.
36-12+9/3 Add 12 and 9 = 21.
36-21/3 Divide 21 by 3 = 7.
36−7 Subtract 7 from 36 to get 29.
Answer:
Image result for Explain the 4 types of transformations
Lesson Summary

Answer:
16П or approximately 50.3)
Step-by-step explanation:
The area of a circle is equal to П*r²
Since the circle is inside a rectangle with side that is equal to 8, we know that d = 8
2r = d
r = 8/2
r = 4
A = П*r²
A = П*16
А = 16П ( or 16*3.141592653589793238... = 50.26548... ≈ 50.3)
Answer:
The expected number of keys she will try before she opens the door is 4.5.
Step-by-step explanation:
A woman has eight keys on a key ring, one of which fits the door she wants to unlock.
Each of them is equally as likely to be the one to work, which means that this situation is represented by an uniform distribution with lower bound and upper bound .
Find the expected number of keys she will try before she opens the door.
The expected value of the uniform distribution is given by:
Considering , as is the case in this exercise:
The expected number of keys she will try before she opens the door is 4.5.
