A^2 - ab + b^2
This is the factoring formula
Answer:
4^(5+2) + 7 - (4^(-3+2) +7)
--------------------------------------
5 +3
Step-by-step explanation:
The average rate of change is given by
h(5) - h(-3)
---------------
5 - -3
h(5) - h(-3)
---------------
5 +3
h(5) = 4^(5+2) + 7
h(-3) = 4^(-3+2) +7
4^(5+2) + 7 - (4^(-3+2) +7)
---------------
5 +3
Step-by-step explanation:
From given data,
n = 1496
x = 478
Proportion estimate ( p ) = 
=
= 0.3195 ≅ 0.31
Proportion estimate ( p ) = 0.31
∴ The proportion of new car buyers who prefer foreign cars -> 0.31
Answer:
6/5
Step-by-step explanation:
Answer:
≈11.4
Step-by-step explanation:
We know that, Ryan lives 2 blocks west and 5 blocks south of Devin
=> Coordinate of Ryan: (-2,-5). Because:
- 2 blocks west = 2 unit to the left = -2
- 5 blocks south = 5 unit go down= -5
Andy lives 7 blocks east and 2 block north of Devin.
=>Coordinate of Andy: (7,2), because:
- 7 blocks east = 7 unit ti the right = 7
- 2 block north = 2 unit go up = 2
Hence, to find out the distance of Ryan and Andy, we use distance formula as below:
≈11.4
