Using the quadratic formula we get
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
Answer:
Step-by-step explanation:
Total number of coins in the bag = 5 + 4 + 5 + 2 = 16 coins
Number of nickels in the bag = 4
We have to find the probability that Marissa draws a nickels from the bag.
Probability is defined as the ratio of Number of "Favorable Outcomes" to "Total number of possible outcomes"
In this case total number of possible outcomes is the total number of coins which is 16.
Favorable/Desires outcome is drawing a Nickle from the bag which are 4 in number. So, number of favorable outcomes is 4
Therefore, the probability that she will draw a nickel =
Hey there!
Ratio = division
now, division of boys over girls
= 6 / 15
= 2 / 5
Ratio = 2 : 5
Hope helps!
