Answer:
b. Continuous
Step-by-step explanation:
Continuous variable is a variable that can take on any value between its minimum value and its maximum value. A continuous variable is a type of quantitative variable used to describe data that is measurable while Discrete variables are countable in a finite amount of time. Now, justifying whether the gallons of gasoline pumped by a filling station during a day is continuous or discrete. The number of gallons of gasoline pumped by a filling during during a day is a continuous variable because it has a measurable volume which can take value from the minimum to maximum values of the total volume of gasoline the filling station have in the storage tank.
I got 54.90196 for that problem
Answer: 0.09
Step-by-step explanation:
From the question, in a physical education class, there are 21 boys and 9 girls. Each day, the teacher randomly selects a team captain randomly.
The probability that the team captain will be a girl two days in a row assuming no student is absent will be:
Boys = 21
Girls = 9
Total = 21 + 9 = 30
P(pick a girl) = 9/30 = 3/10 = 0.3
P(pick a girl 2 days in a row) = (0.3)²
= 0.09
