B. There may be a correlation between having a restaurant and having a greater number of annual visitors.
Correlation can be defined as a relationship between two things. Here, the correlation is between the restaurants and the number of visitors. When they don't have restaurant, the number of visitors must have been low.
A,b are both 45 degrees
c, d are both 90 degrees
add it all together 270 degrees
"2x2 + 3x = −5" should be re-written as 2x^2 + 3x +5 = 0. This is a quadratic equation with a=2, b=3 and c=5. Thus, the roots are:
-3 plus or minus √(9-4[2][5])
x = ---------------------------------------------
4
or:
-3 plus or minus √(-31)
x = ----------------------------------
4
or:
-3 plus or minus i*√31
x = ----------------------------------
