Answer:
Quantitative
Discrete
Ratio
Step-by-step explanation:
The number of days traveled by randomly selected employees is a quantitative variable because it can be presented meaningful numerical form and further the number of days traveled by randomly selected employees are discrete because the number of days can be counted. Now, the level of measurement for the variable "number of days traveled by employees" is  ratio scale because it has a meaningful zero. Meaningful zero in this case will means that none of the day is spent on travelling.

Answer:
b = 10
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =  bh ( b is the base and h the height )
 bh ( b is the base and h the height )
Here h = 3x + 15 and A = 15x + 75, thus
 × b × (3x + 15) = 15x + 75
 × b × (3x + 15) = 15x + 75
Multiply both sides by 2 to clear the fraction
b(3x + 15) = 30x + 150
Divide both sides by (3x + 15)
b =  ← factor numerator and denominator
 ← factor numerator and denominator
   =  ← cancel the factor (x + 5) on numerator/denominator
 ← cancel the factor (x + 5) on numerator/denominator
   = 
   = 10
