Answer:
A. Carla is on the right track because she is finding the slopes of consecutive sides to check for perpendicular sides.
Step-by-step explanation:
Only adjacent sides can be perpendicular, so Jonah's approach of finding slopes of opposite sides cannot work.
Carla is on the right track; choice A.
Answer:
2.8, 8.8, and -17 respectively.
Step-by-step explanation:
We need to find roots of the equation.
Answer:
Part 1) The algebraic expression is equal to
or 
Part 2) The algebraic expression is equal to 
Step-by-step explanation:
Part 1) Algebraic expression of (n-1) increased by 110%
we know that
110%=110/100=1.10
so
The algebraic expression of (n-1) increased by 110% is equal to multiply 1.10 by (n-1)

Distributed

Part 2) Algebraic expression of n^(-1) increased by 110%
we know that
110%=110/100=1.10
so
The algebraic expression of n^(-1) increased by 110% is equal to multiply 1.10 by n^(-1)
Remember that

so

Answer: 0.9013
Step-by-step explanation:
Given mean, u = 10, standard deviation =8
P(X) =P(Z= X - u /S)
We are to find P(X> or =12)
P(X> or = 12) = P(Z> 12-10/8)
P(Z>=2/8) = P(Z >=0.25)
P(Z) = 1 - P(Z<= 0.25)
We read off Z= 0.25 from the normal distribution table
P(Z) = 1 - 0.0987 = 0.9013
Therefore P(X> or=12) = 0.9013
