explanation:
7/8 x 8/3=56/24—simplify—-> 7/3
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:
40

Answer:
8 Minutes
Step-by-step explanation:
since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.
666-562 = 104
Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.
104 / 13 = 8
Polynomials can have REAL ZEROS or COMPLEX ZEROS. Real Zeros to a polynomial are POINTS where the graph crosses the x-axis when y=0. When we graph each function, we can see these points. Complex Zeros are the SOLUTIONS of the equation that ARE NOT VISIBLE on the graph.
