Answer:
Use the equation h(t)=-b/2a to find the x value of the vertex, then plug that back into the equation to find the y value which is your height.
Step-by-step explanation:
You can also complete the square to get the equation into vertex form, then your height is the y value of your vertex. Remember the maximum height is always at the vertex of an inverted parabola.
they took one from 273 and added it back to the fraction but the fraction is /45 so you would add 45 to 9/45
Answer:
Step-by-step explanation:
Problem A
There are four outcomes for the cards
and three outcomes for the marbles
The total number of outcomes is 3 * 4 = 12
Problem B
Now you need 1 in three chances of getting a blue marble while any card will do. So your chances of drawing a blue marble are 1 in 3 and that is your final outcome because the cards don't affect the outcome.
Answer: 1/3
<span>There are several possible events that lead to the eighth mouse tested being the second mouse poisoned. There must be only a single mouse poisoned before the eighth is tested, but this first poisoning could occur with the first, second, third, fourth, fifth, sixth, or seventh mouse. Thus there are seven events that describe the scenario we are concerned with. With each event, we want two particular mice to become diseased (1/6 chance) and the remaining six mice to remain undiseased (5/6 chance). Thus, for each of the seven events, the probability of this event occurring among all events is (1/6)^2(5/6)^6. Since there are seven of these events which are mutually exclusive, we sum the probabilities: our desired probability is 7(1/6)^2(5/6)^6 = (7*5^6)/(6^8).</span>
