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

Answer:
$100
Step-by-step explanation:
We assume you're interested in the revenue collected by the food truck.
6 1/4 pizzas = (6·4+1)/4 = 25/4 = 50/8 pizzas = 50×(1/8 pizza)
If each 1/8 pizza slice is sold for $2, then the revenue is ...
50 × $2 = $100 . . . . revenue from 6 1/4 pizzas
Answer:
I believe the answer is
-14 • 0 + 2x = 6
anything multiplied by zero is zero therefore x equals 3
